Triple-negative breast cancer (TNBC) has poor prognosis. Carboplatin (Crb) is a widely used chemotherapeutic agent, in TNBC but with serious systemic toxicity and poor tumor targeting. Bioinspired drug-loaded platelets (Plt) and Plt-coated nanocarriers evade macrophage phagocytosis by membrane proteins like CD47. The goal of this study was preparation of a novel alginate-poly (β-amino ester) (PβAE) nanoparticles (NPs) for targeted delivery of Crb to TNBC cells by developing and comparison of two bioinspired carriers of Plt membrane (PltM) coated Crb-loaded alginate-poly (β-amino ester) nanoparticles (PltM@Crb-PβAE-ALG NPs) and Plt loaded Crb (Plt@Crb). The NPs were prepared by ionic gelation and subsequently were coated by platelet membrane using ultra-sonication method. The loading efficiency, release profile, and in vitro cytotoxicity of both formulations were evaluated on HUVEC and 4 T1 cells. Additionally, the in vivo tumor targeting, therapeutic efficacy, and organ toxicity of the two formulations were assessed in a murine tumor model. Results showed both Plt@Crb and (PltM@Crb-PβAE-ALG NPs) exhibited high drug loading efficiency, sustained release, enhanced cytotoxicity against 4 T1 cells, and decreased cytotoxicity in normal cells (HUVEC) in vitro. In vivo studies revealed that although both formulations considerably improved tumor inhibition compared to free Crb, but the PltM@Crb-PβAE-ALG NPs demonstrated superior cytotoxicity and therapeutic efficacy, thanks to improved Crb's internalization efficiency, enhanced stability, and controlled release properties., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Background: Perioperative immunotherapy improves short-term outcomes in resectable non-small-cell lung cancer (NSCLC). We now report 5-year survival from the NADIM trial to assess its long-term benefit., Methods: NADIM was a multicentre, single-arm, phase 2 trial conducted across 18 hospitals in Spain. Patients were aged 18 years or older, had an Eastern Cooperative Oncology Group performance status of 0 or 1, and had histologically or cytologically confirmed, treatment-naive, resectable stage IIIA NSCLC (American Joint Committee on Cancer, 7th edition criteria). The neoadjuvant treatment consisted of three cycles of intravenous paclitaxel (200 mg/m 2 ) and carboplatin (area under the curve 6 mg/mL per min) with nivolumab (360 mg). After surgery, 1 year of adjuvant treatment with intravenous nivolumab monotherapy was administered (240 mg every 2 weeks for 4 months, followed by 480 mg every 4 weeks for 8 months). The primary endpoint was 24-month progression-free survival, with 5-year progression-free survival and overall survival as secondary endpoints, assessed in the intention-to-treat population (ie, all patients who received neoadjuvant treatment). Toxicity profile was also assessed as a secondary endpoint. This trial is registered at ClinicalTrials.gov (NCT03081689) and is complete; this is the final report of the trial., Findings: Between April 26, 2017, and Aug 25, 2018, 51 patients were assessed for eligibility, of whom 46 comprised the intention-to-treat population (34 [74%] male and 12 [26%] female, median age 63 years [IQR 58-70]). Follow-up was concluded at 60 months (data cutoff July 11, 2023; median follow-up 60·0 months [IQR 60·0-60·0]). 5-year progression-free survival in the intention-to-treat population was 65·0% (95% CI 49·4-76·9), and overall survival was 69·3% (53·7-80·6). Disease progression occurred in 11 (24%) patients; 14 (30%) patients died, including nine (20%) from disease relapse and five (11%) from non-tumour-related causes. Treatment-related adverse events (TRAEs) of grade 3 or worse occurred in 14 (30%) of 46 patients during neoadjuvant treatment and in seven (19%) of 37 during adjuvant treatment. The most common grade 3 or worse TRAEs were increased lipase and febrile neutropenia (three [7%] each) during neoadjuvant treatment, and elevated serum lipase (four [7%]) and elevated serum amylase (three [8%]) during adjuvant treatment. Serious TRAEs included elevated serum lipase and neutropenia (one [2%] each) during neoadjuvant treatment, and elevated serum lipase (one [3%]) during adjuvant treatment. No treatment-related surgery delays, deaths, or unexpected long-term toxicities were reported., Interpretation: Perioperative chemoimmunotherapy showed a promising long-term benefit with no concerning safety data, reinforcing its use in resectable stage IIIA NSCLC., Funding: Bristol-Myers Squibb, Spanish Ministry of Science, Instituto de Salud Carlos III, European Union., Competing Interests: Declaration of interests MP reports non-financial support (reagents for T-cell receptor sequencing) from ThermoFisher Scientific; grants, consulting fees, and non-financial support from Bristol Myers Squibb, Roche, and AstraZeneca; and consulting fees from MSD and Takeda; outside the submitted work.

Purpose: We assessed the 27-gene RT-qPCR-based DetermaIO assay and the same score calculated from RNA sequencing (RNA-seq) data as predictors of sensitivity to immune checkpoint therapy in the neoTRIPaPDL1 randomized trial that compared neoadjuvant carboplatin/nab-paclitaxel chemotherapy (CT) plus atezolizumab with CT alone in stage II/III triple-negative breast cancer. We also assessed the predictive function of the immuno-oncology (IO) score in expression data of patients treated with pembrolizumab plus paclitaxel (N = 29) or CT alone (N = 56) in the I-SPY2 trial., Experimental Design: RNA-seq data were obtained from pretreatment core biopsies from 242 (93.8%) of the 258 patients in the per-protocol-population. The DetermaIO RT-qPCR test, performed in the CAP/CLIA-accredited laboratory of Oncocyte Corp., was available for 220 patients (85.3%). A previously established threshold was used to assign DetermaIO-positive versus DetermaIO-negative status. Publicly available microarray data were used from I-SPY2., Results: IO scores calculated from RNA-seq and RT-qPCR data were highly concordant. In neoTRIPaPDL1, DetermaIO-positive cancers (N = 92, 41.8%) had pathologic complete response (pCR) rates of 69.8% and 46.9% in the CT + atezolizumab and CT arms, respectively. In DetermaIO-negative cases, pCR rates were similar in both arms (44.6% vs. 49.2%; interaction test P = 0.04). PDL1 protein expression and stromal tumor-infiltrating lymphocyte count were not predictive of differential benefit from atezolizumab. In I-SPY2, IO-positive cancers (45.9%) had pCR rates of 85.7% and 16%, with and without immunotherapy, respectively. In IO-negative cancers, pCR rates were 46.7% versus 16.1%., Conclusions: DetermaIO identified patients who benefited from neoadjuvant immunotherapy resulting in improved pCR rate, independently of PDL1., (©2024 The Authors; Published by the American Association for Cancer Research.)

Introduction: SCT510 is a biosimilar to bevacizumab (Avastin) reference product (RP) that is approved for various metastatic cancers. In this study, we aimed to demonstrate the equivalence of SCT510 and bevacizumab in terms of efficacy, safety, immunogenicity and pharmacokinetics (PK) in patients with advanced non-squamous non-small cell lung cancer (NSCLC)., Methods: Patients with non-squamous NSCLC were randomized equally to the SCT510 group (comprising SCT510, paclitaxel, and carboplatin) and the bevacizumab group (comprising bevacizumab, paclitaxel, and carboplatin) for 4-6 cycles, followed by maintenance monotherapy with SCT510. The primary endpoint was the objective response rate (ORR) at week 12. Secondary endpoints included 18-week ORR, disease control rate (DCR), duration of response (DoR), progression-free survival (PFS), overall survival (OS), and 1-year survival rate, as well as assessments of safety, immunogenicity, and multi-dose PK analysis., Results: Between March 29, 2019, and April 27, 2021, 989 patients were screened and 567 eligible patients were randomly assigned to the SCT510 group (285 patients) and the bevacizumab group (282 patients). The ORR at week 12 was 52.6% [95% confidence interval (CI) 46.66-58.55%] in the SCT510 group and 52.5% (95% CI 46.47-58.47%) in the bevacizumab group. The ORR at week 18 was 55.4% (95% CI 49.46-61.30%) for SCT510 and 55.7% (95% CI 49.68-61.62%) for bevacizumab. The ORR risk ratio (RR) at weeks 12 and 18 was 0.99 (90% CI 0.873-1.133) and 0.99 (90% CI 0.872-1.114), respectively, both within the pre-specified equivalence margin of 0.75-1.33. There were no differences between the two groups in relation to other secondary endpoints, specifically DCR, DOR, PFS, OS, and 1-year survival rate. The overall safety findings were similar between the two treatment groups, and both SCT510 and bevacizumab RP exhibited low immunogenicity., Conclusions: SCT510 is similar to bevacizumab in clinical efficacy, safety, immunogenicity, and PK in patients with advanced non-squamous NSCLC. The totality of the evidence supports the clinical equivalence of SCT510 and bevacizumab., Trial Registration: NCT03792074., (© 2024.

Aims: Thymic carcinoma (TC) is a rare form of highly invasive tumors. Currently, the standard first-line therapy involves paclitaxel plus carboplatin treatment, while the recommended regimen for second-line therapy remains uncertain. The purpose of this study is to explore the second-line mode of TC patients., Materials and Methods: We evaluated the outcome of subjects with advanced TC between 2009 and 2023 in three medical centers, retrospectively. Tumor response was evaluated according to the Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST v1.1). Kaplan-Meier was used for calculating Progression-free survival (PFS) and overall survival (OS). The factors affecting survival in the real world were evaluated by Cox analysis., Results: Totally 136 patients were included in this study, the median PFS (mPFS) for all subjects was 5.97 months, and the median OS (mOS) was 25.03 months. According to patient's treatment modes, they are divided into monotherapy (n = 95) and combination therapy (n = 41), PFS manifested the difference between two groups (5.17 vs. 9.00 months, P = 0.043). OS also indicated a significant distinction (22.50 vs. 38.00 months, P = 0.017). Furthermore, there was a significant difference in PFS between patients using immunotherapy combined with chemotherapy and those with antivascular therapy (8.57 vs. 13.10 months, P = 0.047)., Conclusion: In the second-line therapy for advanced TC, the efficacy of combination therapy was better than monotherapy, especially for immunotherapy combined with antivascular therapy., (Copyright © 2024.

Despite improvements in survival, metastatic castration-resistant prostate cancer (mCRPC) remains a significant clinical challenge. While taxanes, new hormonal agents, radiopharmaceuticals, and PARP inhibitors offer valuable treatment options, this review explores the potential of platinum chemotherapies (carboplatin, cisplatin, and oxaliplatin) as alternative choices. Existing research demonstrates promising preliminary results for platinum-based therapies in mCRPC showing PSA response rates (7.7-95 %) and improved overall survival (8-26.6 months). However, chemotherapy-related cytopenias are a frequent side effect. Further research is underway to evaluate the efficacy of platinum regimens against specific mCRPC histopathological variants, particularly aggressive subtypes where the carboplatin and cabazitaxel combination is already recommended. The unique DNA-targeting action of platinum therapy holds promise for patients with deficient DNA repair (dDDR), especially those with BRCA mutations. This potential is supported by both preclinical and ongoing clinical research. Given the limited success of immunotherapy in mCRPC, researchers are exploring the potential for platinum therapies to enhance its efficacy. Additionally, trials are investigating the synergy of combining platinum therapy with both immunotherapy and PARP inhibitors. Further exploration into the effectiveness of platinum therapies in specific mCRPC subpopulations, particularly those with dDDR, is crucial for optimizing their future use. In conclusion, this review highlights the promising potential of platinum-based chemotherapy as a valuable treatment option for mCRPC. While current evidence is encouraging, ongoing research is essential to further optimize its efficacy, identify optimal combinations with other therapies, and better understand its impact on specific mCRPC subpopulations., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Background: The safety and efficacy of combination of gefitinib with chemotherapy and bevacizumab in treatment patients with epidermal growth factor receptor (EGFR) mutations are currently unknown. This study was designed to evaluate the safety and preliminary efficacy of a combination therapy consisting of gefitinib, bevacizumab, pemetrexed, and carboplatin in patients with advanced non-squamous non-small cell lung cancer (NSCLC) harboring EGFR mutations., Methods: Eligible patients with EGFR-mutated advanced non-squamous NSCLC were recruited and received gefitinib combination with bevacizumab plus pemetrexed and carboplatin treatment. The primary endpoints were safety and progression-free survival (PFS). Secondary endpoints included objective response rate (ORR), disease control rate (DCR), duration of response (DOR), and overall survival (OS)., Results: From June 2019 to June 2021, 20 patients were enrolled in this study. The median follow-up was 33.8 months (95% CI, 31.0-36.6). Grade ≥ 3 adverse events was 65%, including neutropenia (30%), thrombocytopenia (20%), nausea (20%), skin rash (20%), bleeding (10%), and increased ALT (10%). There was no death related to toxicity occurred. The median PFS was 28 months (95% CI, 20.4-35.6). the ORR was 95% (95% CI, 75.1-99.9%), the DCR was 100% (95% CI, 83.2-100%), and the median DOR was 26.4 months (95% CI, 18.9-33.9). The median OS has not been reached., Conclusion: The results of this study demonstrate that the four-drug combination regimen, led by gefitinib, is manageable and tolerated and effective for patients with EGFR-mutated advanced non-squamous NSCLC., (© 2024.

Background: Neoadjuvant chemotherapy may be considered for patients with ovarian cancer (OC) whose tumors are deemed unlikely to be completely cytoreduced to no gross residual disease (R0) or who are poor surgical candidates. This Ib/II study was designed to assess the efficacy and safety of nanoparticle albumin-bound paclitaxel (nab-paclitaxel) plus carboplatin as neoadjuvant chemotherapy for stages III-IV, unresectable OC., Methods: Eligible patients with stage III-IV, unresectable OC were enrolled in this phase Ib/II study. All patients received neoadjuvant nab-paclitaxel (260 mg/m 2 , day 1, every 3 weeks) plus carboplatin (AUC 5, day 1, every 3 weeks) for 3 cycles before surgery, followed by 3-6 cycles of adjuvant chemotherapy. The phase Ib primary endpoint was safety; the phase II primary endpoint was the R0 resection rate. Secondary endpoints were progression-free survival (PFS), overall survival (OS), objective response rate (ORR), and safety (for all populations)., Results: Sixty-two patients were enrolled and were given neoadjuvant therapy treated between October 2019 and December 2020, of whom 9 were in the phase Ib portion and 53 in the phase II portion. A total of 53 patients underwent surgery with an R0 resection rate of 73.6% (95% CI, 59.7-84.7%). With a median follow-up of 17.5 (range 0.7-36.7) months, for all patients, the best ORR was 83.9% (95% CI, 71.7-92.4%) with 47 partial responses, the median PFS was 18.6 (95% CI, 13.8-23.3%) months, and median OS was not reached. During the neoadjuvant chemotherapy, treatment-related adverse events (TRAEs) of any grade occurred in 91.9% (57/62) of all patients. The most common hematologic TRAEs were neutropenia (55/62, 88.7%), and non-hematologic toxicity was alopecia (36/62, 58.1%). Forty-nine patients (79.0%) experienced at least one grade 3-4 TRAEs, with the most common was neutropenia (44/62, 71.0%). Besides, delays in neoadjuvant chemotherapy and surgery due to AEs were observed in 9 (1 in phase Ib; 8 in phase II) and 7 (phase II) patients, respectively., Conclusions: The study demonstrated an encouraging efficacy and manageable safety profile of neoadjuvant chemotherapy nab-paclitaxel plus carboplatin in stage III-IV, unresectable OC. In addition, AEs resulting in chemotherapy and surgery delays should be cautiously considered in this clinical setting., Trial Registration: ClinicalTrials.gov, ChiCTR1900026893.

Background: Despite promising outcomes of treatment with anti-programmed cell death (PD)-1/PD-ligand (L)1 agents in combination with platinum-doublet chemotherapy (PDC) in the first-line setting, a significant unmet medical need remains in patients with PD-L1-unselected non-small cell lung cancer (NSCLC)., Methods: This multicenter, open-label, phase 1b study comprising dose-confirmation and dose-expansion parts investigated the combination of spartalizumab and various PDC regimens, with or without canakinumab, in treatment-naïve patients with PD-L1-unselected, metastatic NSCLC. The primary objectives were to determine maximum tolerated dose (MTD) and/or recommended dose for expansion (RDE) of spartalizumab, with or without canakinumab, in combination with PDC in the dose-confirmation part and antitumor activity of spartalizumab in the dose-expansion part., Results: The MTD/RDE of spartalizumab was 300 mg every 3 weeks (Q3W) when administered with either gemcitabine (1250 mg/m 2 )/cisplatin (75 mg/m 2 ) (group A; no dose-limiting toxicities [DLTs]), pemetrexed (500 mg/m 2 )/cisplatin (group B; 2 DLTs: grade 2 posterior reversible encephalopathy syndrome and grade 4 hyponatremia), or paclitaxel (200 mg/m 2 )/carboplatin area under the curve 6 min*mg/mL (group C; 1 DLT: grade 4 neutropenic colitis). The RDE of canakinumab combined with spartalizumab and pemetrexed/cisplatin (group E; no DLTs) was 200 mg Q3W (no dose-expansion part was initiated). No new safety signals were identified. In groups A, B, C, and E, the overall response rates were 57.6%, 55.3%, 51.5%, and 57.1%, respectively. Group B compared with other groups had the longest median progression-free survival (10.4 months vs. 6.2-7.5 months), overall survival (29.7 months vs. 16.1-21.0 months), and duration of response (30.1 months vs. 6.0-8.2 months)., Conclusions: The combination of spartalizumab and PDC, with or without canakinumab, was well tolerated across treatment groups. The antitumor activity across treatment groups was comparable with that of pembrolizumab and pemetrexed combination. Canakinumab did not appear to improve the antitumor activity when combined with spartalizumab, pemetrexed and cisplatin., Trial Registration: The trial was registered in Clinicaltrials.gov with identifier no. NCT03064854. Date of Registration: 06 February 2017., (© 2024. The Author(s).)

Background: Locally advanced cervical cancer is treated with chemoradiotherapy (standard of care), but many patients still relapse and die from metastatic disease. We investigated chemoradiotherapy with or without induction chemotherapy to determine whether induction chemotherapy improves both progression-free survival and overall survival., Methods: The INTERLACE trial was a multicentre, randomised phase 3 trial done at 32 medical centres in Brazil, India, Italy, Mexico, and the UK. Adults (aged ≥18 years) with locally advanced cervical cancer (FIGO 2008 stage IB1 disease with nodal involvement, or stage IB2, IIA, IIB, IIIB, or IVA disease) were randomly assigned (1:1), by minimisation, using a central electronic system, to standard cisplatin-based chemoradiotherapy (once-a-week intravenous cisplatin 40 mg/m 2 for 5 weeks with 45·0-50·4 Gy external beam radiotherapy delivered in 20-28 fractions plus brachytherapy to achieve a minimum total 2 Gy equivalent dose of 78-86 Gy) alone or induction chemotherapy (once-a-week intravenous carboplatin area under the receiver operator curve 2 and paclitaxel 80 mg/m 2 for 6 weeks) followed by standard cisplatin-based chemoradiotherapy. Stratification factors were recruiting site, stage, nodal status, three-dimensional conformal radiotherapy or intensity modulated radiotherapy, age, tumour size, and histology (squamous vs non-squamous). Primary endpoints were progression-free survival and overall survival within the intention-to-treat population. This trial is registered with ClinicalTrials.gov, NCT01566240, and EUDRACT, 2011-001300-35., Findings: Between Nov 8, 2012, and Nov 17, 2022, 500 eligible patients were enrolled and randomly assigned to the chemoradiotherapy alone group (n=250) or the induction chemotherapy with chemoradiotherapy group. Of 500 patients, 354 (70%) had stage IIB disease and 56 (11%) stage IIIB disease. Pelvic lymph nodes were positive in 215 (43%) patients. 230 (92%) patients who received induction chemotherapy had at least five cycles. Median interval between induction chemotherapy and chemoradiotherapy was 7 days. Four or more cycles of cisplatin were given to 212 (85%) participants in the induction chemotherapy with chemoradiotherapy group and to 224 (90%) of participants in the chemoradiotherapy alone group. 462 (92%) participants received external beam radiotherapy and brachytherapy with a median overall treatment time of 45 days. After a median follow-up of 67 months, 5-year progression-free survival rates were 72% in the induction chemotherapy with chemoradiotherapy group and 64% in the chemoradiotherapy alone group with a hazard ratio (HR) of 0·65 (95% CI 0·46-0·91, p=0·013). 5-year overall survival rates were 80% in the induction chemotherapy with chemoradiotherapy group and 72% in the chemoradiotherapy alone group, with an HR of 0·60 (95% CI 0·40-0·91, p=0·015). Grade 3 or greater adverse events were reported in 147 (59%) of 250 individuals in the induction chemotherapy with chemoradiotherapy group versus 120 (48%) of 250 individuals in the chemoradiotherapy alone group., Interpretation: Short-course induction chemotherapy followed by chemoradiotherapy significantly improves survival of patients with locally advanced cervical cancer., Funding: Cancer Research UK and University College London-University College London Hospitals Biomedical Research Centre., Competing Interests: Declaration of interests GE reports consulting fees from MSD and Eisai; payment or honoraria from Eisai and GSK; support for attending meeting from MSD; and participation on Data Safety Monitoring Board or Advisory Board for GSK, MSD, and Eisai, outside the submitted work.

Background: Current treatment options for patients with locally advanced vulvar cancer are limited and associated with high morbidity. Therefore, it is important to develop new and safe treatment strategies for this vulnerable patient group., Primary Objective: To compare the efficacy and safety of neoadjuvant chemotherapy followed by surgery with definitive chemoradiation in patients with locally advanced vulvar cancer., Study Hypothesis: Neoadjuvant chemotherapy followed by surgery is oncologically safe, potentially more effective than primary chemoradiation in establishing long lasting locoregional control, and associated with an improved quality of life., Trial Design: This study is a multicenter, prospective, phase II randomized controlled trial. Patients will be randomized 1:1 to the standard treatment arm (primary chemoradiation, consisting of a tumor dose of 64.5 Gy in 30 fractions of external beam radiotherapy with weekly cisplatin for 6 weeks) or the experimental treatment arm (neoadjuvant chemotherapy, consisting of carboplatin and paclitaxel in a 3 weekly scheme, followed by surgery)., Major Inclusion/exclusion Criteria: Eligible patients must have a histologically confirmed primary or recurrent locally advanced squamous cell carcinoma of the vulva (International Federation of Gynecology and Obstetrics (FIGO) stages Ib-Iva; Lesions larger than 2 cm in size or stromal invasion larger than 1 mm (T1b or higher), any status of lymph node involvement (any N), no distant metastasis including pelvic lymph nodes (M0)) with the size or localization of the tumor requiring treatment through primary chemoradiation or extensive surgery. Patients with documented metastases of the pelvic lymph nodes will be excluded from participation in this study., Primary Endpoint: Locoregional control at 24 months., Sample Size: 98 patients will be included in the study., Estimated Dates for Completing Accrual and Presenting Results: Expected complete accrual in 2028 with presentation of results by 2030., Trial Registration: ClinicalTrials.gov NCT05905315., Competing Interests: Competing interests: None declared., (© IGCS and ESGO 2024.

Definitive chemoradiotherapy (dCRT) is a potentially curative therapy for esophageal cancer. As indications for dCRT differ widely, it is challenging to draw conclusions on outcomes and survival. The aim of this study was to evaluate overall survival (OS) and recurrence patterns according to indications for treatment. Patients who underwent dCRT (50.4 Gy concomitant with carboplatin/paclitaxel) for esophageal cancer between 2012 and 2022 were identified. Indications for dCRT were: cervical tumor, irresectable disease, unfit for surgery, and patient and/or physician preference. The primary endpoint was OS calculated with the Kaplan-Meier method. Secondary endpoints included the proportion of patients that completed the dCRT regimen, 30- and 90-day mortality, and disease recurrence. One hundred and fifty-seven patients were included (72.6% esophageal squamous cell carcinoma) with a median follow-up of 20 months (IQR 10.0-43.9). The full dCRT regimen was completed by 116 patients (73.9%). Thirty- and 90-day mortality were 2.5% and 8.3%, respectively. Median and 5-year OS for all patients were 22.9 months (95% CI 18.0-27.9) and 31.4%, respectively. The median OS per indication was 23.7 months (95% CI 6.5-40.8) for patients with cervical tumors, 10.9 months (95% 0.0-23.2) for irresectable disease, 28.2 months (95% CI 12.3-44.0) for unfit patients, and 22.9 months (95% CI 15.4-30.5) for patients' preference for dCRT (P = 0.11). Disease recurrence was observed in 74 patients (46%), located locoregionally (46%), distant (19%), or combined (35%). Patients who underwent dCRT had a 5-year OS of 31.4%, but OS differed according to indications for treatment with patients who had irresectable disease having the worst prognosis., (© The Author(s) 2024.

Purpose: First-line tislelizumab plus chemotherapy significantly improved progression-free survival (PFS) versus chemotherapy alone in advanced squamous non-small-cell lung cancer (sq-NSCLC) at the interim analysis of the phase III RATIONALE-307 trial. We present the final analysis of this trial., Patients and Methods: Patients with treatment-naive, stage IIIB/IV, sq-NSCLC were randomized (1 : 1: 1) to 21-day cycles of i.v.: tislelizumab plus paclitaxel and carboplatin (arm A); tislelizumab plus nab-paclitaxel and carboplatin (arm B); or paclitaxel and carboplatin (arm C). The primary endpoint was independent review committee-assessed PFS; overall survival was a secondary endpoint., Results: In total, 360 patients were randomized; 355 received treatment. At the final analysis (median study follow-up: 16.7 months), tislelizumab plus chemotherapy had a manageable safety profile, consistent with that at the interim analysis. Improvement in PFS was maintained for arms A and B versus C {hazard ratio (HR) 0.45 [95% confidence interval (CI) 0.33-0.62] and 0.43 (95% CI 0.31-0.60), respectively}. Overall survival HRs for arms A and B versus C were 0.68 (95% CI 0.46-1.01) and 0.75 (95% CI 0.50-1.12), respectively., Conclusions: The RATIONALE-307 final analysis demonstrated superior clinical benefit with addition of tislelizumab to chemotherapy, and a manageable safety profile, as first-line treatment of advanced sq-NSCLC., (Copyright © 2024 The Authors.

An intracoelomic mass was palpated on an annual exam of a 24-year-old male Solomon Island eclectus parrot ( Eclectus roratus solomonensis ). The initial diagnostic workup included a complete blood count, plasma biochemistry panel, and coelomic ultrasound. Computed tomography was highly suggestive of a testicular mass. Tamoxifen and the gonadotropin-releasing hormone agonists leuprolide and deslorelin were administered as neoadjunctive endocrine therapies. Biopsy and histologic examination confirmed a testicular mass consistent with a round cell tumor. Four doses of carboplatin 15 mg/kg IV were administered as neoadjunctive chemotherapy, and testicular size decreased by approximately 95%. The remaining gross tumor was removed via orchidectomy with clean but narrow margins. Seven months following surgery, a contrast CT scan did not show any evidence of recurrence of or metastasis from the original mass. This is the first report of successful treatment of a testicular tumor in a psittacine with neoadjuvant chemotherapy and orchidectomy.

Purpose: Epidermal growth factor receptor (EGFR) pathway activation causes chemotherapy resistance, and inhibition of the EGFR pathway sensitizes triple-negative breast cancer (TNBC) cells to chemotherapy in preclinical models. Given the high prevalence of EGFR overexpression in TNBC, we conducted a single-arm phase II study of panitumumab (anti-EGFR monoclonal antibody), carboplatin, and paclitaxel as the second phase of neoadjuvant therapy (NAT) in patients with doxorubicin and cyclophosphamide (AC)-resistant TNBC (NCT02593175)., Patients and Methods: Patients with early-stage, AC-resistant TNBC, defined as disease progression or ≤80% reduction in tumor volume after four cycles of AC, were eligible for this study and received panitumumab (2.5 mg/kg i.v., every week × 13), paclitaxel (80 mg/m2 i.v. every week × 12), and carboplatin (AUC = 4 i.v., every 3 weeks × 4) as the second phase of NAT. A two-stage Gehan-type design was used to detect an improvement in the pathological complete response (pCR)/residual cancer burden class I (RCB-I) rate from 5% to 20%. Whole-exome sequencing was performed on diagnostic tumor biospecimens, where available., Results: From November 3, 2016, through August 23, 2021, 43 patients with AC-resistant TNBC were enrolled. The combined pCR/RCB-I rate was 30.2%. The most common treatment-related adverse events were neutropenia (72%) and anemia (61%), with 7 (16%), 16 (37%), and 8 (19%) patients experiencing grade 4 neutropenia, grade 3 neutropenia, and grade 3 anemia, respectively. No new safety signals were observed., Conclusions: This study met its primary endpoint (pCR/RCB-I = 30.2% vs. 5% in historical controls), suggesting that panitumumab should be evaluated as a component of NAT in patients with chemotherapy-resistant TNBC in a larger, randomized clinical trial., Significance: The epidermal growth factor receptor (EGFR) pathway has been implicated as a driver of chemotherapy resistance in triple-negative breast cancer (TNBC). Here, we evaluate the combination of panitumumab, carboplatin, and paclitaxel as the second phase of neoadjuvant therapy (NAT) in patients with AC-resistant TNBC. This study met its primary efficacy endpoint, and molecular alterations in EGFR pathway genes did not seem to influence response to the study regimen., (©2024 The Authors; Published by the American Association for Cancer Research.)

Immunotherapy with anti-PD-1 antibodies significantly improved the prognosis in advanced melanoma patients, but most of them develop primary or secondary resistance to the treatment. In this study, we evaluated efficacy and safety of a chemotherapy regimen with weekly carboplatin plus paclitaxel (wCP) in patients previously treated with anti-PD-1 antibodies. We retrospectively identified 30 patients with advanced melanoma treated at our Institute over the last eight years with wCP. The co-primary endpoints of the study were overall survival (OS) and progression-free survival (PFS). In addition, we evaluated treatment tolerability. For this patient cohort, median PFS and OS were 3.25 and 7.69 months, respectively. All included patients had previously received anti-PD-1 immunotherapy, most of them had ECOG PS 0-1, and only 5 patients had a BRAF V600 mutation. In univariable analysis, we observed shorter OS in patients with > 2 involved metastatic sites, superficial spreading histology, and serum lactate dehydrogenase (LDH) values above the median. Liver metastases were associated with worse outcomes, while radiotherapy treatment of brain metastases was associated with improved OS. However, in a multivariable Cox regression model, only LDH above the median, superficial spreading histology, and female sex were significantly associated with worse OS. We reported grade 3 and 4 treatment-related toxicities in 4 and 0 patients, respectively. In conclusion, chemotherapy with wCP is a valid palliative treatment in advanced melanoma who progressed with anti-PD-1 antibodies., (© 2024. The Author(s).)

Treatment of relapsed or refractory diffuse large B-cell lymphoma is difficult. The de novo diffuse large B-cell lymphoma has better prognosis than the transformed diffuse large B-cell lymphoma. The response of CHOP or a similar regimen has an important role in determining response to salvage therapy, in relapse or refractory diffuse large B-cell lymphoma patients. Patients who are non-responder to initial treatment have a very poor chance of responding to therapy for relapse. This was a small scale observational study and was conducted from January 2017 to December 2020 in National Institute of Cancer Research and Hospital, Bangladesh. A total of 34 patients with relapsed or refractory diffuse large B-cell lymphoma were identified at hematology department in National Institute of Cancer Research and Hospital, 28 of them were treated with ICE chemotherapy and 6 with R-ICE chemotherapy as second line regimen. Overall response rate to 2nd line chemotherapy was 64.8%, with 32.4% (11 patients) complete remission and 32.4% (11 patients) partial remission. Median overall survival to second line regimen was 10 months, corresponding to a 4 year overall survival of 32.4% and a 4 year progression free survival was 17.6%. Patient with stable disease/progressive disease median overall survival was 7 months compared with 15 months for complete remission and 9 months for partial remission (p<0.001). Median overall survival was significantly better in patients with international prognostic index 0-2 compared in those with international prognostic index >2 (p=0.010). However improvement of salvage efficacy is an urgent need with new drugs. Further studies are necessary to determine whether this regimen will improve outcomes of relapsed or refractory diffuse large B-cell lymphoma patients.

Objectives: Certain guidelines recommend caution when administering immunotherapy in patients with pre-existing interstitial lung disease (ILD) owing to the high incidence of pneumonitis induced by anti-cancer therapy. A prospective clinical trial assessing the safety of chemoimmunotherapy in patients with small-cell lung cancer (SCLC) and pre-existing ILD is warranted. Therefore, this study evaluated the safety and efficacy of chemoimmunotherapy in patients with extensive-stage (ES)-SCLC and mild idiopathic interstitial pneumonia (IIP)., Methods: In this multicenter prospective trial, patients with ES-SCLC and pre-existing mild chronic fibrosing IIP were recruited. Mild IIP was defined as the exclusion of poor pulmonary function, a definite usual interstitial pneumonia (UIP) pattern, and positivity for autoantibodies in blood tests. The patients received durvalumab, etoposide, and carboplatin every three weeks (induction phase), followed by 1,500 mg durvalumab every four weeks (maintenance phase). The primary endpoint was severe pneumonitis-free rate., Results: Twenty-one patients were included in the analysis. Among them, 13 patients displayed a probable UIP pattern, whereas eight patients exhibited an indeterminate for UIP pattern. Two patients (9.5 %) had pneumonitis of any grade during the induction phase; one had Grade 1 and the other had Grade 5 pneumonitis. No other patient developed pneumonitis during the maintenance phase. The severe pneumonitis-free rate was 95.2 % (95 % confidence interval (CI): 77.3-99.2 %). The median progression-free survival was 5.5 months (95 % CI: 3.6-6.4 months). Median overall survival was 10.7 months (95 % CI: 6.0 months to not reached)., Conclusions: Chemoimmunotherapy is a feasible treatment approach for patients with ES-SCLC and mild IIP., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: [Daichi Fujimoto reports financial support provided by AstraZeneca K.K.

Objectives: IMbrella A is a Phase III extension study that allowed rollover from Roche/Genentech-sponsored atezolizumab trials, including IMpower133, a Phase I/III trial of first-line atezolizumab or placebo plus carboplatin/etoposide in extensive-stage small cell lung cancer. We report outcomes from an exploratory analysis of IMpower133 with extended time-to-event data for patients who rolled over to IMbrella A., Materials and Methods: IMpower133 patients could roll over to IMbrella A to receive atezolizumab 1200 mg intravenously every three weeks if they continued to receive atezolizumab at IMpower133 closure or were in survival follow-up after atezolizumab discontinuation. Overall survival and safety were assessed; only serious adverse events and AEs of special interest were collected in IMbrella A., Results: Eighteen of 26 eligible patients rolled over to IMbrella A. At clinical cutoff (March 16, 2023), median follow-up in the atezolizumab plus carboplatin/etoposide arm (IMpower133 and IMbrella A) was 59.4 months. The three-, four-, and five-year overall survival (95 % CI) estimates were 16 % (11 %-21 %), 13 % (8 %-18 %), and 12 % (7 %-17 %), respectively. In IMbrella A, serious adverse events occurred in three patients (16.7 %), and one adverse event of special interest was reported (grade two hypothyroidism)., Conclusion: This long-term analysis of patients from IMbrella A previously enrolled in IMpower133 provides the first report of five-year overall survival outcomes in patients with extensive-stage small cell lung cancer treated with first-line cancer immunotherapy and chemotherapy. While limited by small patient numbers and lack of long-term data for the IMpower133 control arm, exploratory overall survival analyses in patients treated with atezolizumab plus carboplatin/etoposide compared favorably with historical data with chemotherapy alone.

BACKGROUND AND OBJECTIVE: Recent trials have shown that immune checkpoint inhibitors (ICIs), atezolizumab and durvalumab, in combination with chemotherapy, are effective in treating extensive-disease small-cell lung cancer (ED-SCLC). However, owing to the expensiveness of ICIs, monetary issues arise. The cost-effectiveness of ICI combination treatment with carboplatin plus etoposide (CE) as first-line therapy for patients with ED-SCLC was examined to aid public health policy in Japan., Methods: IMpower 133 and CASPIAN data were used to create a partitioned survival model. Medical expenses and quality-adjusted life years (QALYs) were considered. The analysis period, discount rate, and threshold were set at 20 years, 2%, and 15 million Japanese yen (JPY) [114,068 US dollars (USD)] per QALY, respectively. The incremental cost-effectiveness ratio (ICER) was calculated by gathering reasonable parameters from published reports and combining the costs and effects using parametric models. Monte Carlo simulations, scenario analysis, and one-way sensitivity analyses were employed to quantify uncertainty., Results: After comparing atezolizumab plus CE (ACE) and durvalumab plus CE (DCE) with CE, it was found that the ICERs exceeded the threshold at 35,048,299 JPY (266,527 USD) and 36,665,583 JPY (278,826 USD) per QALY, respectively. For one-way sensitivity and scenario assessments, the ICERs exceeded the threshold, even with considerably adjusted parameters. For the probabilistic sensitivity analyses, there was no probability that the ICER of the ICI combination treatment with chemotherapy would fall below the threshold., Conclusion: ACE and DCE were not cost-effective compared with CE as first-line therapy for ED-SCLC in Japan. Both these therapies exhibited high ICERs., (© 2024. The Author(s).)

Background: Concurrent chemoradiotherapy is the standard therapy for locally advanced non-small cell lung cancer (NSCLC). However, there is little evidence supporting its use in older adults. Low-dose daily carboplatin combined with thoracic radiotherapy is considered a standard regimen for this population. To establish a simple and feasible carboplatin administration method, we conducted a study of weekly carboplatin and concurrent radiotherapy for older adults with locally advanced NSCLC., Methods: This prospective, single-arm, multicenter, phase II clinical trial included patients aged ≥75 years with unresectable stage III NSCLC and Eastern Cooperative Oncology Group performance status 0-1. Patients received chemoradiotherapy (60 Gy/30 fractions plus concurrent weekly carboplatin at an area under curve of 2 mg mL -1  min -1 ). The primary endpoint was the overall response rate (ORR). Key secondary endpoints included progression-free survival (PFS), overall survival (OS), and safety., Results: From July 2020 to June 2022, 37 patients were enrolled from 15 institutions, and 36 patients were evaluable for efficacy and safety. The ORR was 63.9% (95% confidence interval [CI] = 47.6-77.5). Median PFS was 14.6 months (95% CI = 9.1-18.1). Median OS was 25.5 months (95% CI = 17.4-not reached). Grade 4 leucopenia, neutropenia, and thrombocytopenia were observed in one patient (2.8%) each., Conclusion: Weekly carboplatin and concurrent radiation therapy was safe in older adults with locally advanced NSCLC, and promising activity was observed., (© 2024 The Author(s).

Pulmonary tumor thrombotic microangiopathy (PTTM) is a rapidly progressive cancer-related disease with a dismal clinical course. The patient in this report was a 43-year-old man with metastatic salivary duct carcinoma arising from the parotid gland. Combined androgen blockade therapy was administered started as first-line treatment, but failed after 5 months, followed by docetaxel plus carboplatin therapy as second-line treatment, which failed after 3 months. Genomic profiling revealed a BRAF V600E mutation, and combined BRAF and MEK inhibitor therapy was started as third-line treatment. The cancer remained stable during the first 10 months of third-line treatment, but treatment was subsequently discontinued due to the onset of symptoms of fatigue, myalgia and arthritis. Twenty days after the onset of these symptoms and interruption of third-line treatment, the patient was urgently admitted to hospital with respiratory distress and severe thrombocytopenia. CT images at the time of admission led our radiologist to the possibility of PTTM, but the patient died the day after admission and autopsy findings indicated that PTTM was the cause of death. This report describes a very informative case of PTTM with sequential imaging and detailed autopsy findings were available and provides a literature review., Competing Interests: Declaration of competing interest Three of the authors (Yoshitaka Honma, Ken Kato, Masahiko Kusumoto) declare the following financial interests/personal relationships which may be considered as potential competing interests: 1) Yoshitaka Honma has received compensation as a member of the advisory role of Janssen, Eisai, and Rakuten Medical Japan; received honoraria from Novartis, Chugai pharma, MSD, Ono pharmaceutical, Bristol Myers Squibb, Merck Biopharma, Eisai, Eli Lilly, Nutri, Teijin pharma, Bayer, and Taiho pharmaceutical; and received research funding from Taiho pharmaceutical, Chugai pharma, MSD, GlaxoSmithKline, Janssen, Adlai Nortye Biopharma, Maruho, Merck Biopharma, Genmab, Astellas pharma, Rakuten Medical Japan, and AstraZeneca. 2) Ken Kato reports funding to the institution from Merck Sharp & Dohme Corp (MSD), Ono Pharmaceuticals, Bristol Myers Squibb (BMS), Beigene, Shionogi, Merck Biopharma, Oncolys BioPharma, Daiichi Sankyo, Novartis, Taiho Pharmaceutical, Janssen, AstraZeneca, and Chugai. 3) Masahiko Kusumoto received honoraria for lecture fees from Daiichi-Sankyo Co.,Ltd.

Immunochemotherapy is the first-line standard for extensive-stage small-cell lung cancer (ES-SCLC). Combining the regimen with anti-angiogenesis may improve efficacy. ETER701 was a multicenter, double-blind, randomized, placebo-controlled phase 3 trial that investigated the efficacy and safety of benmelstobart (a novel programmed death-ligand 1 (PD-L1) inhibitor) with anlotinib (a multi-target anti-angiogenic small molecule) and standard chemotherapy in treatment-naive ES-SCLC. The ETER701 trial assessed two primary endpoints: Independent Review Committee-assessed progression-free survival per RECIST 1.1 and overall survival (OS). Here the prespecified final progression-free survival and interim OS analysis is reported. Patients randomly received benmelstobart and anlotinib plus etoposide/carboplatin (EC; n = 246), placebo and anlotinib plus EC (n = 245) or double placebo plus EC ('EC alone'; n = 247), followed by matching maintenance therapy. Compared with EC alone, median OS was prolonged with benmelstobart and anlotinib plus EC (19.3 versus 11.9 months; hazard ratio 0.61; P = 0.0002), while improvement of OS was not statistically significant with anlotinib plus EC (13.3 versus 11.9 months; hazard ratio 0.86; P = 0.1723). The incidence of grade 3 or higher treatment-related adverse events was 93.1%, 94.3% and 87.0% in the benmelstobart and anlotinib plus EC, anlotinib plus EC, and EC alone groups, respectively. This study of immunochemotherapy plus multi-target anti-angiogenesis as first-line treatment achieved a median OS greater than recorded in prior randomized studies in patients with ES-SCLC. The safety profile was assessed as tolerable and manageable. Our findings suggest that the addition of anti-angiogenesis therapy to immunochemotherapy may represent an efficacious and safe approach to the management of ES-SCLC.

Background: In KEYNOTE-522 (NCT03036488), neoadjuvant pembrolizumab plus chemotherapy and then adjuvant pembrolizumab significantly improved pathological complete response and event-free survival vs neoadjuvant chemotherapy in early-stage triple-negative breast cancer (TNBC). We report patient-reported outcomes (PROs) from KEYNOTE-522., Methods: Patients were randomized 2:1 to neoadjuvant pembrolizumab 200 mg or placebo every 3 weeks, plus 4 cycles of paclitaxel plus carboplatin and then 4 cycles of doxorubicin (or epirubicin) plus cyclophosphamide. After surgery, patients received adjuvant pembrolizumab or placebo for up to 9 cycles. European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) and EORTC Breast Cancer-Specific Quality of Life Questionnaire (EORTC QLQ-BR23) were prespecified secondary objectives. Between-group differences in least squares (LS) mean change from baseline (day 1 of cycle 1 in both neoadjuvant and adjuvant phases) to the prespecified latest time point with at least 60% completion and at least 80% compliance were assessed using a longitudinal model (no alpha error assigned)., Results: Week 21 (neoadjuvant phase) and week 24 (adjuvant phase) were the latest time points at which completion/compliance rates were ≥60%/80%. In the neoadjuvant phase, between-group differences (pembrolizumab plus chemotherapy [n = 762] vs placebo plus chemotherapy [n = 383]) in LS mean change from baseline to week 21 in QLQ-C30 global health status/quality of life (GHS/QoL), emotional functioning, and physical functioning were -1.04 (95% confidence interval = -3.46 to 1.38), -0.69 (95% CI = -3.13 to 1.75), and -2.85 (95% CI = -5.11 to -0.60), respectively. In the adjuvant phase, between-group differences (pembrolizumab [n = 539] vs placebo [n = 308]) in LS mean change from baseline to week 24 were -0.41 (95% CI = -2.60 to 1.77), -0.60 (95% CI = -2.99 to 1.79), and -1.57 (95% CI = -3.36 to 0.21)., Conclusions: No substantial differences in PRO assessments were observed between neoadjuvant pembrolizumab plus chemotherapy followed by adjuvant pembrolizumab vs neoadjuvant placebo plus chemotherapy in early-stage TNBC., Trial Registration: ClinicalTrials.gov, NCT03036488., (© The Author(s) 2024.

Purpose: We aimed to investigate the safety and efficacy of HL301, a standardized combination product of 7 medicinal plants, in radiation pneumonitis in patients with unresectable non-small cell lung cancer undergoing curative concurrent chemoradiotherapy., Methods and Materials: The target accrual was 87 and a total of 63 patients were enrolled due to poor accrual rate. We randomly assigned the 63 patients to receive a placebo (arm A), or 1200 mg HL301 (arm B), or 1800 mg HL301 (arm C). Patients received weekly paclitaxel and carboplatin concurrently with intensity-modulated radiation therapy at 60 to 66 Gy in conventional fractionation. Durvalumab was administered as a maintenance treatment according to standard clinical practice. HL301 was administered orally, daily for 12 weeks. The primary endpoint was incidence of grade ≥2 radiation pneumonitis at 24 weeks postchemoradiotherapy., Results: The baseline characteristics of the patients were well balanced. The drug was tolerable with a compliance rate of 86.6%, 86.2%, and 88.8% in arms A, B, and C, respectively (P = .874). None of the patients experienced severe drug-related adverse events. No significant difference in the rate of adverse events were observed between the treatment arms. The incidence of grade ≥2 radiation pneumonitis at 24 weeks postchemoradiotherapy was 37.5% (95% CI, 18.5%-61.4%), 55.6% (95% CI, 33.7%-75.4%), and 52.4% (95% CI, 32.4%-71.7%) in arms A, B, and C, respectively (P = .535)., Conclusions: This is the first exploratory clinical trial to test the safety and efficacy of HL301 in patients with non-small cell lung cancer. Safety and feasibility of HL301 were established but no signals of efficacy in reducing radiation pneumonitis was observed in this dose level., (Copyright © 2024 Elsevier Inc. All rights reserved.)

Background: Pre-clinical data suggests a potential synergistic effect of eribulin and platinum. However, clinical data on the combination for metastatic breast cancer (mBC) is lacking. We evaluated the efficacy and safety of eribulin plus carboplatin (ErCb) in patients with mBC., Patients and Methods: This multicenter, real-world cohort study included patients with pre-treated metastatic triple negative breast cancer (TNBC) or endocrine-refractory hormone receptor (HR) positive, HER2-negative mBC who received ErCb. Eribulin (1.4 mg/m2) and carboplatin (target AUC = 2) were administered intravenously on day 1 and 8 of 21-day cycle. Objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and adverse events (AEs) were evaluated., Results: From March 2022 to December 2023, a cohort of 37 patients were recruited to the study. Among them, 22 patients have TNBC and 15 have HR + HER2 - mBC. Of the 22 patients with TNBC, 8 had an initial diagnosis of the HR + HER2 - subtype. The median treatment was 6 cycles (range, 2 - 8 cycles). In the full cohort, TNBC, and HR + HER2 - subgroup, the ORR were 51.4%, 54.5% and 46.7%, the DCR were 81.1%, 81.8% and 80%, and the median PFS were 5 months, 5 months, and 5.2 months, respectively. The median OS was 12.7 months in the entire cohort and 12.8 months in TNBC subgroup. The most common grade 3/4 hematological AEs were neutropenia (37.8%), leukopenia (35.1%), febrile neutropenia (10.8%), thrombocytopenia (5.4%), and anemia (2.7%). No grade 3/4 non-hematological AEs were observed., Conclusion: ErCb demonstrated favorable efficacy and tolerability in patients with heavily pre-treated mBC, especially TNBC. The findings of the current study warrant further investigation of the application of this combination in earlier lines of mBC treatment., (© 2024. The Author(s).)

Objectives: This qualitative study explored patients' experiences and perceptions of the SCOPE2 trial. SCOPE2 examined radiotherapy dose escalation in patients with inoperable oesophageal cancer treated with definitive chemoradiotherapy (dCRT)., Setting: Recruitment at five clinical sites in England and Wales, UK., Participants: SCOPE2 trial participants were invited to take part in interviews from across five clinical sites. Participants self-selected to take part in up to three interviews across four different time points: baseline (before treatment) and at 2-3 months, 3-6 months or 6 months+ after baseline. There were five female and five male interview participants., Interventions: Participants were randomised to standard dose dCRT prescribed carboplatin/paclitaxel or cisplatin/capecitabine, or an escalated dose dCRT prescribed carboplatin/paclitaxel or cisplatin/capecitabine., Methods: This qualitative study used semistructured longitudinal interviews to explore the impact of treatment on patient outlook and quality of life and the impact of the COVID-19 pandemic. Interview data were thematically analysed., Results: 10 patients participated in 16 longitudinal interviews. Three participants were accompanied by companions. Participants experienced side-effects from radiotherapy and chemotherapy including nausea, throat pain, difficulties eating and regaining appetite, thrombosis and fatigue, although most of these symptoms gradually improved. Participants required more ongoing information and support regarding treatment side-effects and cancer status in order to improve their overall quality of life. Best practice examples involved key contacts providing practical advice and signposting support., Conclusion: Participants of the SCOPE2 trial reported short and longer-term side-effects from chemoradiotherapy, but these usually lessened over time. Participants attempted to be positive about their survival prospects by readjusting their expectations, priorities and lifestyles. Providing patients with ongoing opportunities to discuss detailed and timely information regarding treatment side-effects, aftercare and cancer status could improve the overall health and well-being of patients during oesophageal cancer trials and pathways., Trial Registration Number: NCT02741856; ISRCTN: 97125464., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

A Japanese clinical trial (JGOG3016) showed that dose-dense weekly paclitaxel in combination with carboplatin extensively prolonged overall survival (OS) in patients with advanced ovarian cancer. However, in other clinical trials, dose-dense paclitaxel regimens were not superior to triweekly paclitaxel regimens. In this study, causal tree analysis was applied to explore subpopulations with different treatment effects of dose-dense paclitaxel in a data-driven approach. The 587 participants with stage II-IV ovarian cancer in the JGOG3016 trial were used for model development. The primary endpoint was treatment effect in terms of 3-year OS in patients receiving dose-dense vs. conventional paclitaxel therapies. In patients <50 years, the 3-year OS was similar in both groups; however, it was higher in the dose-dense group in patients ≥50 years. Dose-dense paclitaxel showed strong positive treatment effects in patients ≥50 years with stage II/III disease, BMI <23 kg/m 2 , non-CC/MC, and residual tumor ≥1 cm. In contrast, although there was no significant difference in OS; the 3-year OS rate was 23% lower in dose-dense paclitaxel than conventional paclitaxel in patients ≥60 years with stage IV cancer. Patients in this group had a particularly lower performance status than other groups. Our causal tree analysis suggested that poor prognosis groups represented by residual tumor tissue ≥1 cm benefit from dose-dense paclitaxel, whereas elderly patients with advanced disease and low-performance status are negatively impacted by dose-dense paclitaxel. These subpopulations will be of interest to future validation studies. Personalized treatments based on clinical features are expected to improve advanced ovarian cancer prognosis., (© 2024 The Authors.

Background: Patients with relapsed primary mediastinal nonseminomatous germ cell tumor have low cure rates with salvage chemotherapy or surgery. The authors report survival outcomes of patients who received high-dose chemotherapy (HDCT) and peripheral blood stem cell transplantation (PBSCT) at Indiana University., Methods: The prospectively maintained Indiana University germ cell tumor database identified 32 patients with primary mediastinal nonseminomatous germ cell tumor who progressed after first-line cisplatin-based combination chemotherapy and received HDCT and PBSCT between 2006 and 2021. Therapy included two consecutive courses of HDCT consisting of 700 mg/m 2 carboplatin and 750 mg/m 2 etoposide, each for 3 consecutive days, and each followed by PBSCT. A second course was not given if the patient experienced progressive disease or prohibitive toxicity. Progression-free survival and overall survival were analyzed using the Kaplan-Meier method. Medians with 95% confidence intervals were also calculated along with 2-year probabilities., Results: The median age at HDCT was 30 years (range, 18-61 years). With a median follow-up of 4.7 years (range, 1-14 years), the 2-year progression-free survival rate was 31% (95% confidence interval, 16%-47%), and the 2-year overall survival rate was 35% (95% confidence interval, 19%-52%). At last follow-up, nine patients (28%) remained without evidence of disease, including two platinum-refractory patients and two patients who were receiving HDCT as third-line therapy. There were three treatment-related deaths., Conclusions: Salvage HDCT and PBSCT is an active combination in patients who have relapsed primary mediastinal nonseminomatous germ cell tumor with curative potential and prolonged survival, including in platinum-refractory and third-line settings. The authors recommend this approach for initial salvage chemotherapy in this patient population., (© 2024 The Authors.

Purpose: The phase II, multiarm, signal-searching BALTIC study (NCT02937818) assessed novel treatment combinations for platinum-refractory/resistant extensive-stage small cell lung cancer (ES-SCLC)., Patients and Methods: Patients with ES-SCLC with progressive disease during or within 90 days of completing first-line platinum-based chemotherapy received one of three regimens: durvalumab plus tremelimumab followed by durvalumab monotherapy (arm A), adavosertib plus carboplatin (arm B), or ceralasertib plus olaparib (arm C). The primary endpoint was the objective response rate. Prespecified exploratory biomarker analyses were conducted in arms A and C., Results: In arm A (n = 41), arm B (n = 10), and arm C (n = 21), the confirmed objective response rates were 7.3%, 0%, and 4.8%, respectively. Safety profiles in all arms were consistent with those of the individual drugs. In arm A, patients with PD-L1 expression (tumor cells or immune cells) ≥1% seemed to have a greater likelihood of achieving disease control with durvalumab plus tremelimumab than those with PD-L1 (tumor cells and immune cells) <1%, and lower baseline ctDNA and reduction in the on-treatment ctDNA level were both associated with longer overall survival. Among patients treated with ceralasertib plus olaparib in arm C, specific immune response-relevant circulating chemokines and cytokines were identified as early biomarkers of survival and pharmacodynamic biomarkers., Conclusions: In BALTIC, all combination regimens demonstrated tolerable safety profiles, but antitumor activity was limited in refractory/resistant ES-SCLC. Among patients treated with durvalumab plus tremelimumab, an association of on-treatment reduction in ctDNA with longer overall survival suggests the potential use of ctDNA as a surrogate of treatment response, warranting further investigation., (©2024 The Authors; Published by the American Association for Cancer Research.)

Aim: Dose-dense paclitaxel /carboplatin (ddTC) therapy was shown to be more effective against ovarian cancer than conventional tri-weekly TC in the JGOG3016 study. However, two phase III studies performed after JGOG3016 did not show the same positive results. Because we have been using ddTC in the frontline or first platinum-sensitive relapse of ovarian cancer, we investigated the clinical outcome of the patients treated with ddTC., Methods: We retrospectively examined the response rate (RR), progression free survival (PFS) and adverse events of the patients who were treated with ddTC for stage III and IV epithelial ovarian, tubal and peritoneal cancer from January 2012 to December 2018., Results: We analyzed 50 patients for frontline treatment and 11 patients for first platinum-sensitive relapse treatment, excluding those receiving maintenance therapy. Among the patients that received frontline ddTC treatment, RR was 82.9% for those in a neo-adjuvant chemotherapy (NACT) setting and 85.0% for those in an adjuvant setting. The median progression-free survival (PFS) was 20 months after initial therapy. Among 31 cases that achieved remission by frontline surgery and the following ddTC, 22 had a platinum-sensitive relapse. RR of 11 patients treated with ddTC therapy alone for the first platinum-sensitive relapse was 81.8%, and the median PFS of these patients was 22 months after the first recurrence., Conclusions: ddTC therapy for advanced ovarian cancer achieved high response rates in all settings (NACT, adjuvant or platinum-sensitive relapse). ddTC therapy was effective for improving the prognosis of patients with stages III and IV of ovarian cancer., (© 2024 Japan Society of Obstetrics and Gynecology.)

Background: At the time of AtTEnd trial design, standard treatment for advanced or recurrent endometrial cancer included carboplatin and paclitaxel chemotherapy. This trial assessed whether combining atezolizumab with chemotherapy might improve outcomes in this population., Methods: AtTEnd was a multicentre, double-blind, randomised, placebo-controlled, phase 3 trial done in 89 hospitals in 11 countries across Europe, Australia, New Zealand, and Asia. Enrolled patients were aged 18 years or older, and had advanced or recurrent endometrial carcinoma or carcinosarcoma, an Eastern Cooperative Oncology Group performance status of 0-2, and received no previous systemic chemotherapy for recurrence. Patients were randomly assigned (2:1) using an interactive web response system (block size of six) to either atezolizumab 1200 mg or placebo given intravenously with chemotherapy (carboplatin at area under the curve of 5 or 6 and paclitaxel 175 mg/m 2 intravenously on day 1 every 21 days) for 6-8 cycles, then continued until progression. Stratification factors were country, histological subtype, advanced or recurrent status, and mismatch repair (MMR) status. Participants and treating clinicians were masked to group allocation. The hierarchically tested co-primary endpoints were progression-free survival (in patients with MMR-deficient [dMMR] tumours, and in the overall population) and overall survival (in the overall population). Primary analyses were done in the intention-to-treat population, defined as all randomly assigned patients who gave their full consent to participation in the study and data processing. Safety was assessed in all patients included in the intention-to-treat population who received at least one dose of study treatment. Here, we report the primary progression-free survival and the interim overall survival results. This study is ongoing and is registered with ClinicalTrials.gov, NCT03603184., Findings: Between Oct 3, 2018, and Jan 7, 2022, 551 patients were randomly assigned to atezolizumab (n=362) or placebo (n=189). Two patients in the atezolizumab group were excluded from all analyses due to lack of consent. Median follow-up was 28·3 months (IQR 21·2-37·6). 81 (23%) patients in the atezolizumab group and 44 (23%) patients in the placebo group had dMMR disease by central assessment. In the dMMR population, median progression-free survival was not estimable (95% CI 12·4 months-not estimable [NE]) in the atezolizumab group and 6·9 months (6·3-10·1) in the placebo group (hazard ratio [HR] 0·36, 95% CI 0·23-0·57; p=0·0005). In the overall population, median progression-free survival was 10·1 months (95% CI 9·5-12·3) in the atezolizumab group and 8·9 months (8·1-9·6) in the placebo group (HR 0·74, 95% CI 0·61-0·91; p=0·022). Median overall survival was 38·7 months (95% CI 30·6-NE) in the atezolizumab group and 30·2 months (25·0-37·2) in the placebo group (HR 0·82, 95% CI 0·63-1·07; log-rank p=0·048). The p value for the interim analysis of overall survival did not cross the stopping boundary; therefore, the trial will continue until the required number of events are recorded. The most common grade 3-4 adverse events were neutropenia (97 [27%] of 356 patients in the atezolizumab group vs 51 [28%] of 185 in the placebo group) and anaemia (49 [14%] vs 24 [13%]). Treatment-related serious adverse events occurred in 46 (13%) patients in the atezolizumab group and six (3%) patients in the placebo group. Treatment-related deaths occurred in two patients (pneumonia in one patient in each group)., Interpretation: Atezolizumab plus chemotherapy increased progression-free survival in patients with advanced or recurrent endometrial carcinoma, particularly in those with dMMR carcinomas, suggesting the addition of atezolizumab to standard chemotherapy as first-line treatment in this specific subgroup., Funding: F Hoffmann-La Roche., Competing Interests: Declaration of interests EB, FG, ER, and SU report grants from Roche to their institution to support the conduct of the study.

Objective: First-line bevacizumab plus carboplatin and paclitaxel (CP) is approved for stage III/IV ovarian cancer treatment following initial surgical resection, based on global phase III GOG-0218 and ICON7 trials. This study evaluated the efficacy and safety of bevacizumab + CP as first-line ovarian cancer therapy in Chinese patients., Methods: Patients with newly diagnosed, International Federation of Gynecology and Obstetrics (FIGO) stage III/IV epithelial ovarian, fallopian tube, or primary peritoneal cancer post-primary surgery were randomized 1:1 to receive 6 cycles of CP with bevacizumab/placebo, followed by bevacizumab/placebo maintenance until unacceptable toxicity or disease progression. Primary endpoint was investigator-assessed progression-free survival (PFS). Stratification factors were FIGO stage and debulking status (stage III optimally debulked vs stage III suboptimally debulked vs stage IV) and Eastern Cooperative Oncology Group performance status (0 vs 1 or 2)., Results: Of randomized patients, 51 received bevacizumab + CP and 49 received placebo + CP. Median PFS was 22.6 months with bevacizumab + CP (95% confidence interval [CI]=18.6, not estimable) and 12.3 months (95% CI=9.5, 15.0) with placebo + CP (stratified hazard ratio=0.30; 95% CI=0.17, 0.53). Treatment-related grade 3/4 adverse events occurred in 46 of 49 (94%) patients receiving bevacizumab + CP, and 34 of 50 (68%) receiving placebo + CP., Conclusion: Bevacizumab + CP showed clinically meaningful improvement in PFS vs placebo + CP, consistent with GOG-0218 results. Safety data were aligned with the known bevacizumab safety profile. These results support first-line bevacizumab + CP therapy in Chinese patients with ovarian cancer., Trial Registration: ClinicalTrials.gov Identifier: NCT03635489., Competing Interests: W.X., L.J., A.R., Y.R., Z.Y., Z.H., H.A., W.L., Z.J., L.Z., D.W., Z.J., L.G., C.G., C.Y., and X.F. received institute research funding from F.

Introduction: Chemotherapy-induced nausea and vomiting (CINV) is one of the adverse events that most affects oncologic patients' quality of life. Carboplatin AUC ≥ 4 belongs to agents with high emetic risk (moderate risk in ASCO guidelines). We aimed to compare the effectiveness of netupitant/palonosetron and dexamethasone triple combination (TC) therapy versus ondansetron and dexamethasone double combination (DC) therapy as antiemetic prophylaxis in patients with carboplatin AUC ≥ 4. As a secondary endpoint, in TC group we evaluated the effectiveness of changing NEPA administration timing from 1 h to 15 min before chemotherapy., Methods: Open-label prospective study conducted in a tertiary-care hospital in patients receiving carboplatin AUC ≥ 4. CINV was evaluated using MASCC antiemetic tool, in acute (<24 h) and delayed phase (24-120 h). Results were analyzed using χ 2 test., Results: Two-hundred four completed questionnaires (CQ) were analyzed (76 in DC and 128 in TC). The proportion of patients who remained emesis-free was superior for TC-treated group compared to DC, either in acute (99.2% vs 92.1%, p  = 0.0115) and delayed phase (97.6% vs 90.7%, p  = 0.043). Likewise, a higher proportion of TC-treated patients compared to DC remained nausea-free for the first 24 h after treatment (90.6% vs 71%, p  = 0.0004) and between 24 and 120 h (82.3% vs 62.7%, p  = 0.0025). The change of NEPA administration time showed similar effectiveness in terms of CINV control (81.6% vs 74.5%, p  = 0.70)., Conclusions: TC showed superiority in early and delayed CINV control in carboplatin AUC ≥ 4 regimens, with no significant differences among cancer types. Change in NEPA administration timing has beneficial implications; it allows NEPA to be administered at hospitals before chemotherapy session., Competing Interests: Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Importance: Outcomes for patients with unresectable stage III non-small cell lung cancer (NSCLC) treated with chemoradiation therapy (CRT) have improved with adjuvant immune checkpoint inhibitors, with a reported 5-year overall survival benefit of approximately 10% for adjuvant durvalumab vs placebo after completion of CRT without progression and with preserved performance status. Starting atezolizumab prior to CRT may allow more patients to benefit from immunotherapy., Objective: To evaluate clinical outcomes of patients treated with atezolizumab before and after CRT for unresectable stage III NSCLC., Design, Setting, and Participants: This single-cohort, phase II, nonrandomized controlled trial was conducted at 11 US sites. Patients with pathologically confirmed, unresectable stage III NSCLC who were treatment naive and had good performance status were enrolled between January 3, 2018, and July 24, 2019. Data were locked on March 21, 2023., Interventions: Patients received four 21-day cycles of atezolizumab, 1200 mg intravenously, with therapy administered on day 1 of each cycle. Patients not experiencing tumor progression continued to CRT (60 Gy to involved fields) concurrent with weekly carboplatin area under the curve of 2 and paclitaxel, 50 mg/m2, followed by planned consolidation carboplatin area under the curve of 6 and paclitaxel, 200 mg/m2, for two 21-day cycles. Patients not experiencing progression continued atezolizumab, 1200 mg, every 21 days to complete 1 year of therapy., Main Outcomes and Measures: The primary end point was the disease control rate at 12 weeks. Secondary end points were progression-free survival, overall survival, overall response rate, safety, and translational science end points., Results: A total of 62 patients (median [range] age, 63.9 [38.1-86.5] years; 32 female [51.6%]) were enrolled and received at least 1 dose of atezolizumab. The disease control rate at 12 weeks was 74.2% (80% CI, 65.7%-81.4%). Median progression-free survival was 30.0 months (95% CI, 15.8 to not evaluable), and the median overall survival was not reached. The overall survival rate at 24 months was 73.7% (95% CI, 63.4%-85.7%), and the overall response rate was 66.2%. Seventeen patients (27.4%) experienced grade 3 or higher immune-related adverse events, including 1 with grade 5 pneumonitis and 1 with grade 4 Guillain-Barré syndrome. Thirty patients (48.4%) experienced grade 3 or higher treatment-related adverse events., Conclusions and Relevance: These findings suggest that neoadjuvant atezolizumab merits further study based on safety and encouraging outcomes., Trial Registration: ClinicalTrials.gov Identifier: NCT03102242.

Background: Thoracic radiation intensification is debated in patients with stage III non-small-cell lung cancer (NSCLC). We aimed to assess the activity and safety of a boost radiotherapy dose up to 74 Gy in a functional sub-volume given according to on-treatment [ 18 F]fluorodeoxyglucose ([ 18 F]FDG)-PET results., Methods: In this multicentre, randomised, controlled non-comparative phase 2 trial, we recruited patients aged 18 years or older with inoperable stage III NSCLC without EGFR mutation or ALK rearrangement with an Eastern Cooperative Oncology Group performance status of 0-1, and who were affiliated with or a beneficiary of a social benefit system, with evaluable tumour or node lesions, preserved lung function, and who were amenable to curative-intent radiochemotherapy. Patients were randomly allocated using a central interactive web-response system in a non-masked method (1:1; minimisation method used [random factor of 0·8]; stratified by radiotherapy technique [intensity-modulated radiotherapy vs three-dimensional conformal radiotherapy] and by centre at which patients were treated) either to the experimental adaptive radiotherapy group A, in which only patients with positive residual metabolism on [ 18 F]FDG-PET at 42 Gy received a boost radiotherapy (up to 74 Gy in 33 fractions), with all other patients receiving standard radiotherapy dosing (66 Gy in 33 fractions over 6·5 weeks), or to the standard radiotherapy group B (66 Gy in 33 fractions) over 6·5 weeks. All patients received two cycles of induction platinum-based chemotherapy cycles (paclitaxel 175 mg/m 2 intravenously once every 3 weeks and carboplatin area under the curve [AUC]=6 once every 3 weeks, or cisplatin 80 mg/m 2 intravenously once every 3 weeks and vinorelbine 30 mg/m 2 intravenously on day 1 and 60 mg/m 2 orally [or 30 mg/m 2 intravenously] on day 8 once every 3 weeks). Then they concomitantly received radiochemotherapy with platinum-based chemotherapy (three cycles for 8 weeks, with once per week paclitaxel 40 mg/m 2 intravenously and carboplatin AUC=2 or cisplatin 80 mg/m 2 intravenously and vinorelbine 20 mg/m 2 intravenously on day 1 and 40 mg/m 2 orally (or 20 mg/m 2 intravenously) on day 8 in 21-day cycles). The primary endpoint was the 15-month local control rate in the eligible patients who received at least one dose of concomitant radiochemotherapy. This RTEP7-IFCT-1402 trial is registered with ClinicalTrials.gov (NCT02473133), and is ongoing., Findings: From Nov 12, 2015, to July 7, 2021, we randomly assigned 158 patients (47 [30%] women and 111 [70%] men) to either the boosted radiotherapy group A (81 [51%]) or to the standard radiotherapy group B (77 [49%)]. In group A, 80 (99%) patients received induction chemotherapy and 68 (84%) received radiochemotherapy, of whom 48 (71%) with residual uptake on [ 18 F]FDG-PET after 42 Gy received a radiotherapy boost. In group B, all 77 patients received induction chemotherapy and 73 (95%) received radiochemotherapy. At the final analysis, the median follow-up for eligible patients who received radiochemotherapy (n=140) was 45·1 months (95% CI 39·3-48·3). The 15-month local control rate was 77·6% (95% CI 67·6-87·6%) in group A and 71·2% (95% CI 60·8-81·6%) in group B. Acute (within 90 days from radiochemotherapy initiation) grade 3-4 adverse events were observed in 20 (29%) of 68 patients in group A and 33 (45%) of 73 patients in group B, including serious adverse events in five (7%) patients in group A and ten (14%) patients in group B. The most common grade 3-4 adverse events were febrile neutropenia (seven [10%] of 68 in group A vs 16 [22%] of 73 in group B), and anaemia (five [7%] vs nine [12%]). In the acute phase, two deaths (3%) occurred in group B (one due to a septic shock related to chemotherapy, and the other due to haemotypsia not related to study treatment), and no deaths occurred in group A. After 90 days, one additional treatment-unrelated death occurred in group A and two deaths events occurred in group B (one radiation pneumonitis and one pneumonia unrelated to treatment)., Interpretation: A thoracic radiotherapy boost, based on interim [ 18 F]FDG-PET, led to a meaningful local control rate with no difference in adverse events between the two groups in organs at risk, in contrast with previous attempts at thoracic radiation intensification, warranting a randomised phase 3 evaluation of such [ 18 F]FDG-PET-guided radiotherapy dose adaptation in patients with stage III NSCLC., Funding: Programme Hospitalier de Recherche Clinique National 2014., Competing Interests: Declaration of interests EM declared payment or honoraria for lectures, presentations, speakers bureaus, manuscript writing, or educational events from Varian Medical Systems, AstraZeneca, MSD, Janssen, and Sanofi; support for attending meetings or travel, or both, from Ipsen, Janssen, and AstraZeneca; and participation on a data safety monitoring board or advisory board for AstraZeneca and Janssen.

Purpose: HER2-targeted therapies have dramatically improved outcomes of patients with HER2-positive breast cancer (BC), as demonstrated in neoadjuvant trials. This study aims to provide real-world evidence on the use and effectiveness of combined pertuzumab, trastuzumab and chemotherapy (CT) in early-stage HER2-positive BC., Methods: A retrospective, multicentre study was conducted on patients diagnosed with HER2-positive early BC treated with neoadjuvant pertuzumab and trastuzumab plus CT at 13 Spanish sites. The primary endpoint was pathological complete response (pCR)., Results: A total of 310 patients were included. Pertuzumab and trastuzumab were combined with anthracyclines and taxanes, carboplatin and docetaxel, and taxane-based CT in 77.1%, 16.5%, and 6.5% of patients, respectively. Overall, the pCR rate was 62.2%. The pCR was higher amongst patients with hormone receptor-negative tumours and with tumours expressing higher levels of Ki-67 (> 20%). After postoperative adjuvant treatment, 13.9% of patients relapsed. Those patients who did not achieve pCR, with tumours at advanced stages (III), and with node-positive disease were more likely to experience distant relapse. Median overall survival (OS) and distant disease-free survival (D-DFS) were not reached at the study end. The estimated mean OS and D-DFS times were 7.5 (95% CI 7.3-7.7) and 7.3 (95% CI 7.1-7.5) years, respectively (both were significantly longer amongst patients who achieved pCR). Grade 3-4 anti-HER2 related toxicities were reported in six (1.9%) patients., Conclusion: Neoadjuvant pertuzumab and trastuzumab plus CT achieve high pCR rates in real-life patients with HER2-positive early BC, showing an acceptable safety profile. Innovative adjuvant strategies are essential in patients at high risk of distant disease recurrence., (© 2024. The Author(s).)

Introduction: Atezolizumab, bevacizumab, carboplatin, and paclitaxel (ABCP) combination therapy is a standard of care for advanced non-squamous non-small cell lung cancer (NSQ-NSCLC); however, the lack of safety data limits its clinical application in Japan., Methods: This study compared the safety of ABCP with that of bevacizumab, carboplatin, and paclitaxel (BCP) combination for the treatment of advanced NSQ-NSCLC in Japanese patients by evaluating the clinical background and incidence of adverse events (AEs) based on data extracted from the Diagnosis Procedure Combination (DPC) database. Incidence rates and restricted mean survival times (RMSTs) for up to 1 year were analyzed for 19 clinically important AEs. Covariates were adjusted using the inverse probability weighting method., Results: A search conducted using the International Statistical Classification of Diseases and Related Health Problems 10th Revision codes identified 350,987 patients, of whom 202 were included in the ABCP cohort and 232 in the BCP cohort. Among the 19 AEs, the incidence of skin disorder and febrile neutropenia (FN) was significantly higher in the ABCP cohort versus the BCP cohort. The adjusted incidence rate ratios were 2.65 [95% confidence interval (CI) 1.43-4.91] for skin disorder and 1.70 (95% CI 1.01-2.85) for FN. The adjusted RMST differences were - 64.2 days (95% CI - 93.0 to - 35.4 days) and - 46.0 days (95% CI - 73.5 to - 18.5 days) for skin disorder and FN, respectively. These results were comparable to those of other pivotal clinical trials., Conclusions: The findings of this DPC database study highlight the safety of ABCP in Japanese clinical practice, and this methodology may facilitate more efficient research in real-world settings., Trial Registration: UMIN Clinical Trials Registry ID UMIN000041507., (© 2024.

Background: Platinum/taxane (TC) chemotherapy with debulking surgery stays the mainstay of the treatment in ovarian cancer patients with peritoneal metastasis, and recently its novel modality, intraperitoneal carboplatin with dose-dense paclitaxel (ddTCip), was shown to have greater therapeutic impact. Nevertheless, the response varies among patients and consequent recurrence, or relapse often occurs. Discovery of therapeutic response predictor to ddTCip and/or TC therapy is eagerly awaited to improve the treatment outcome., Methods: Using datasets in 76 participants in our ddTCip study and published databases on patients received TC therapy, we first validated a total of 75 previously suggested markers, sought out more active biomarkers through the association analyses of genome-wide transcriptome and genotyping data with progression-free survival (PFS) and adverse events, and then developed multiplex statistical prediction models for PFS and toxicity by mainly using multiple regression analysis and the classification and regression tree (CART) algorithm., Results: The association analyses revealed that SPINK1 could be a possible biomarker of ddTCip efficacy, while ABCB1 rs1045642 and ERCC1 rs11615 would be a predictor of hematologic toxicity and peripheral neuropathy, respectively. Multiple regression analyses and CART algorithm finally provided a potent efficacy prediction model using 5 gene expression data and robust multiplex toxicity prediction models-CART models using a total of 4 genotype combinations and multiple regression models using 15 polymorphisms on 12 genes., Conclusion: Biomarkers and multiplex models composed here could work well in the response prediction of ddTCip and/or TC therapy, which might contribute to realize optimal selection of the key therapy., (© 2024.

Background: Chemotherapy has limited efficacy in advanced digestive high-grade neuroendocrine neoplasms (HG-NEN) and prognosis is dismal. Predictive markers for palliative chemotherapy are lacking, and prognostic markers are limited., Methods: Digestive HG-NEN patients (n = 229) were prospectively included 2013-2017. Pathological re-assessment revealed 188 neuroendocrine carcinomas (NEC) and 41 neuroendocrine tumours (NET G3). Tumour-DNA was sequenced across 360 cancer-related genes, assessing mutations (mut) and copy number alterations. We linked sequencing results to clinical information and explored potential markers for first-line chemotherapy efficacy and survival., Results: In NEC given cis/carboplatin and etoposide (PE), TP53mut predicted inferior response rate in multivariate analyses (p = 0.009) and no BRAFmut NEC showed response. In overall assessment of PE-treated NEC, no genetic alterations were prognostic for OS. For small-cell NEC, TP53mut were associated with longer OS (p = 0.011) and RB1 deletions predicted lack of immediate-progression (p = 0.003). In non-small cell NEC, APC mut were associated with immediate-progression and shorter PFS (p = 0.008/p = 0.004). For NET G3, ATRXmut, ARID1A- and ERS1 deletions were associated with shorter PFS., Conclusion: Correlations between genetic alterations and response/immediate-progression to PE were frequent in NEC but affected PFS or OS only when subdividing for cell-type. The classification of digestive NEC into large- and small-cell seems therefore molecularly and clinically relevant., (© 2024. The Author(s).)

Background: Evidence regarding chemosensitivity to different therapeutic regimens in epithelial ovarian cancer (EOC) remains limited. This study aimed to investigate EOC implementation in daily clinical practice and reveal favorable regimens for EOC among Japanese patients., Methods: We retrospectively collected clinical data of patients newly diagnosed with EOC from 2012 to 2021 at our affiliated institutions. We evaluated overall survival (OS) and progression-free survival (PFS) of conventional paclitaxel plus carboplatin (TC) vs. dose-dense TC (ddTC) according to the eligibility of GOG262 and JGOG3016 and those with bevacizumab (BEV) vs. without BEV based on GOG218. Further, we evaluated OS and PFS of ddTC and ddTC + BEV to TC + BEV among patients with stage III/IV., Results: The ddTC group (n = 402) demonstrated longer PFS and OS than the TC group (n = 165) (adjusted hazard ratios [aHRs] [95% confidential intervals (CIs)]: 0.69 [0.55-0.88] and 0.67 [0.50-0.90], respectively). The group with BEV (n = 158) demonstrated a longer PFS than those without BEV (n = 296) (0.74 [0.57-0.95]), but not for OS (0.84 [0.60-1.17]). The ddTC and ddTC + BEV groups (n = 259 and 117) demonstrated no statistically significant differences in PFS and OS than the TC + BEV group (n = 75) (1.09 [0.79-1.50] and 0.74 [0.52-1.08] for PFS and 0.89 [0.59-1.34] and 0.73 [0.50-1.05] for OS, respectively)., Conclusion: Our study may indicate ddTC, BEV, and their combination regimen as the promising first-line chemotherapy option among Japanese patients with advanced EOC., (© 2024.

Background: Thymic carcinoma (TC) is a rare tumor with aggressive behavior. Chemotherapy with carboplatin plus paclitaxel represents the treatment of choice for advanced disease. Antiangiogenic drugs, including ramucirumab, have shown activity in previously treated patients. The RELEVENT trial was designed to evaluate the activity and safety of ramucirumab plus chemotherapy as first-line treatment in advanced TC., Patients and Methods: This phase II trial was conducted within the Italian TYME network. Eligible patients had treatment-naïve advanced TC. They received ramucirumab, carboplatin and paclitaxel for six cycles, followed by ramucirumab maintenance until disease progression or intolerable toxicity. Primary endpoint was objective response rate (ORR) according to RECIST v1.1 as assessed by the investigator. Secondary endpoints were progression-free survival (PFS), overall survival (OS) and safety. Centralized radiologic review was carried out., Results: From November 2018 to June 2023, 52 patients were screened and 35 were enrolled. Median age was 60.8 years, 71.4% of patients were male and 85.7% had Masaoka-Koga stage IVB. The Eastern Cooperative Oncology Group performance status was 0 in 68.5% and 1 in 31.4% of patients. At the present analysis carried out some months after the interim analysis (earlier than expected) on 35 patients, ORR was 80.0% [95% confidence interval (CI) 63.1% to 91.6%]. At the centralized radiological review of 33/35 assessable patients, ORR was 57.6% (95% CI 39.2% to 74.5%). After a median follow-up of 31.6 months, median PFS was 18.1 months (95% CI 10.8-52.3 months) and median OS was 43.8 months (95% CI 31.9 months-not reached). Thirty-two out of 35 patients (91.4%) experienced at least one treatment-related adverse event (AE), of which 48.6% were AE ≥ grade 3., Conclusions: In previously untreated advanced TC, the addition of ramucirumab to carboplatin and paclitaxel showed the highest activity compared to historical controls, with a manageable safety profile. Despite the small number of patients, given the rarity of the disease, the trial results support the consideration of this combination as first-line treatment in TC., (Copyright © 2024 The Authors.

Electrochemotherapy (ECT) with intravenous (IV) and/or intratumoral (IT) bleomycin has shown considerable efficacy in the treatment of non-resectable feline cutaneous squamous cell carcinoma (cSCC), boasting response rates of up to 95%, but other chemotherapy protocols have not yet been investigated. The objective of this prospective multicentre study was to compare the overall response rate (ORR) and progression-free interval (PFI) between cats with cSCC treated with ECT using IT and IV carboplatin (IV + IT), IV carboplatin (IV) or IV bleomycin (IV). A total of 44 cats with unresectable cSCC across three centres were enrolled and treated with ECT using carboplatin IV + IT (n = 10), carboplatin IV (n = 11) or bleomycin IV (n = 23). Treatment response according to RECIST criteria was recorded at 2 and 4 weeks post-treatment, and patients were followed until disease progression and/or death. All three groups were comparable regarding age, sex, weight, and lesion size. Adverse events were generally mild, localised and similar between groups. ORRs were 90.0% (carboplatin IV + IT), 90.9% (carboplatin IV) and 95.6% (bleomycin IV) and were not significantly different (p = 0.79). Median PFI was not reached for carboplatin IV + IT or carboplatin IV and was 566 days for bleomycin IV, with no significant difference between the three groups (p = 0.81). This study suggests that ECT using IV or IV + IT carboplatin is a reasonable alternative therapeutic option for managing cSCC, and further studies are warranted to compare outcomes between treatment protocols., (© 2024 The Author(s).

Purpose: Standard-of-care first-line treatment for recurrent/metastatic head and neck squamous cell carcinoma (R/M HNSCC) is pembrolizumab plus platinum and fluorouracil (FU). However, FU is associated with potential challenges (continuous 4-day infusion, high administration costs, and cardiovascular and gastrointestinal toxicities), creating a clinical need for alternative chemotherapy combinations. We evaluated the efficacy and safety of first-line pembrolizumab plus carboplatin and paclitaxel for R/M HNSCC in the open-label, single-arm, phase IV KEYNOTE-B10 study (ClinicalTrials.gov identifier: NCT04489888)., Methods: Eligible adults had previously untreated, histologically or cytologically confirmed R/M HNSCC regardless of PD-L1 status, measurable disease per RECIST v1.1 by blinded independent central review (BICR), and an Eastern Cooperative Oncology Group performance status of 0 or 1. Patients received pembrolizumab 200 mg intravenously once every 3 weeks for ≤35 cycles and carboplatin AUC 5 mg/mL/min intravenously once every 3 weeks for ≤6 cycles and investigator's choice of paclitaxel 100 mg/m 2 on days 1 and 8 or 175 mg/m 2 on day 1, intravenously once every 3 weeks. The primary end point was objective response rate per RECIST v1.1 by BICR., Results: Between October 27, 2020, and April 29, 2022, 149 patients were screened and 101 received treatment. As of February 20, 2023, the median follow-up was 18.9 months (range, 9.1-27.0). At this final analysis, 49 (49%) of 101 patients had an objective response (95% CI, 38.4 to 58.7), including seven patients (7%) with a confirmed complete response. Of the 101 treated patients, grade 3-5 and serious treatment-related adverse events occurred in 76 (75%) and 27 (27%), respectively. There were no new safety signals., Conclusion: Pembrolizumab plus carboplatin and paclitaxel showed promising antitumor activity and a manageable safety profile in first-line R/M HNSCC, suggesting this combination may be an alternative option for this patient population.

Postoperative radiotherapy remains the gold standard for malignant glioma treatment. Clinical limitations, including tumor growth between surgery and radiotherapy and the emergence of radioresistance, reduce treatment effectiveness and result in local disease progression. This study aimed to develop a local drug delivery system to inhibit tumor growth before radiotherapy and enhance the subsequent anticancer effects of limited-dose radiotherapy. We developed a compound of carboplatin-loaded hydrogel (CPH) incorporated with carboplatin-loaded calcium carbonate (CPCC) to enable two-stage (peritumoral and intracellular) release of carboplatin to initially inhibit tumor growth and to synergize with limited-dose radiation (10 Gy in a single fraction) to eliminate malignant glioma (ALTS1C1 cells) in a C57BL/6 mouse subcutaneous tumor model. The doses of carboplatin in CPH and CPCC treatments were 150 μL (carboplatin concentration of 5 mg/mL) and 15 mg (carboplatin concentration of 4.1 μg/mg), respectively. Mice receiving the combination of CPH-CPCC treatment and limited-dose radiation exhibited significantly reduced tumor growth volume compared to those receiving double-dose radiation alone. Furthermore, combining CPH-CPCC treatment with limited-dose radiation resulted in significantly longer progression-free survival than combining CPH treatment with limited-dose radiation. Local CPH-CPCC delivery synergized effectively with limited-dose radiation to eliminate mouse glioma, offering a promising solution for overcoming clinical limitations., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Background: Optic pathway gliomas (OPG) are rare tumors in children. Lesion extent, visual functions, neurofibromatosis 1 (NF1), and age are factors that guide treatment. This study evaluates the clinical characteristics, treatment, and outcome of children and adolescents with OPG treated over a 31-year period in a single center., Methods: Ninety-five patients with OPG diagnosed between January 1990 and December 2021 were retrospectively evaluated. First-line chemotherapy regimen consisted of vincristine and carboplatinum for 1 year. Radiotherapy was not used as first-line treatment and tried to be avoided in the ones who progressed after first-line treatment., Results: Ninety-five children (44 male, 51 female) with a median age of 52 (1-216) months were evaluated. Sixty-three (66.3%) had NF1 and 10 (10,5%) diencephalic syndrome. The most common presenting symptoms were visual abnormalities and/or proptosis, nistagmus, and behavioral changes. Twenty-one (22.1%) patients with NF1 had stable disease throughout the follow-up period and received no treatment. Sixty-three of 74 patients received treatment at diagnosis and 11 due to progression during follow-up. Only one adolescent received radiotherapy at progression. Patients who progressed, received further line systemic treatment (vinblastine; bevacizumab; vincristine-cisplatinum-etoposide). Ten-year overall survival in all patients, in patients with NF1, and without NF1 were 97.2%, 98%, and 95.8% (p > .05), respectively; 10-year progression-free survival (PFS) in all patients, in patients with NF1, and without NF1 were 71.6%, 85.7%, and 54.2% (p = .001), respectively., Conclusions: In children with symptomatic/progressive OPG, chemotherapy consisting of vincristine-carboplatinum (VC) is effective. Radiotherapy may be avoided, especially in patients with NF1., (© 2024 The Author(s). Pediatric Blood & Cancer published by Wiley Periodicals LLC.)

Background: High dose rate (HDR) image-guided brachytherapy with Cobalt-60 isotope is a relatively recent approach. The aim of the study is to evaluate the clinical and dosimetric parameters in terms of tumour response, bladder, and rectal toxicity in patients undergoing Co-60 HDR brachytherapy., Materials and Method: All patients were initially treated with chemoradiation (CT-RT) at our center or other referral centers with external beam radiation therapy (EBRT) for a dose of 45 Gy-60 Gy at 1.8-2Gy/fraction (including nodal boost) with concomitant chemotherapy with either cisplatin or carboplatin. Patients were then scheduled for brachytherapy within 1 week after completion of CT-RT and are assessed by local examination. Depending on local examination parameters at the time of brachytherapy they were eligible either for intracavitary brachytherapy (ICBT) or interstitial brachytherapy (ISBT)., Results: The complete response (CR) observed in stage I, II, III, IVA were 60%, 79.4%, 86% and 76.2% respectively. Complete response was seen in patients with mean EQD2 of 78.67 Gy 10 , 83.33 Gy 10 , 84.23 Gy 10 , 85.63 Gy 10 in stages I, II, III, IVA respectively. 79.2% of cisplatin-treated patients and 87.5% of carboplatin-treated patients had a complete response indicating that patients treated with either chemotherapy had similar response rates., Conclusions: According to results obtained from the study we conclude by saying that higher rates of complete response to treatment in cervical cancer is seen in patients with shorter overall treatment time (OTT), shorter interval between end of definitive CT-RT and beginning of brachytherapy and squamous cell histology. The study also noted the trend of increasing mean EQD2 to tumor with increasing stage for achieving complete response. Higher acute bladder and rectal toxicity is seen in patients who received EQD2 of ¿70-90Gy 3 and ¿70Gy 3 respectively. The study findings suggest that the clinical outcomes and the toxicities are clinically comparable with other radioisotope based HDR brachytherapy treatment., Competing Interests: The authors declare there are no competing interests., (©2024 Makkapati et al.)

Background: TCbHP (taxane + carboplatin + trastuzumab + pertuzumab) is the preferred neoadjuvant therapy regimen for human epidermal growth factor receptor 2 (HER2)-positive breast cancer. However, no consensus exists regarding whether specific populations may be exempt from carboplatin, allowing for de-escalation to the THP (taxane + trastuzumab + pertuzumab) regimen. Additionally, the optimal number of cycles for neoadjuvant THP remains unclear. We compared the efficacy and safety of neoadjuvant TCbHP and THP regimens, providing clinicians with a nuanced perspective to guide their treatment regimen selection., Methods: This multicenter real-world study included patients with HER2-positive breast cancer undergoing neoadjuvant TCbHP or THP between March 2019 and February 2023. Efficacy was assessed through the pathological complete response (pCR) rate, while safety was evaluated through monitoring adverse events., Results: Among 220 patients, 103 received 6 cycles of TCbHP (TCbHP×6), 83 received 6 cycles of THP (THP×6), and 34 received 4 cycles of THP (THP×4). The TCbHP×6 cohort exhibited a 66% pCR rate compared with 53% in the THP×6 cohort (P = 0.072). Subgroup analysis revealed that in patients aged ≤ 50 years, those with hormone receptor (HR)-negative status, and those with clinical stage T2, the pCR rate of the TCbHP×6 regimen was significantly higher than the THP×6 regimen (P < 0.05). The TCbHP×6 cohort reported higher frequencies of any-grade adverse events (99% versus 86.7%) and grade 3-4 events (49.5% versus 12%) than the THP×6 cohort. Propensity score matching identified 27 patient pairs between the THP×6 and THP×4 cohorts, indicating a significantly higher pCR rate for the THP×6 regimen than the THP×4 regimen (63% versus 29.6%, P = 0.029)., Conclusions: The TCbHP×6 regimen is favored for individuals aged ≤ 50 years and those aged > 50, ≤60 years with HR-negative status or clinical stage T2-4. For patients in compromised general condition or lacking the specified indications, the THP×6 regimen emerges as a lower-toxicity alternative with satisfactory efficacy. To ensure treatment efficacy, a minimum of 6 cycles of neoadjuvant THP is required., (© 2024. The Author(s).)

This single-arm phase 2 trial (ChiCTR2100046715) examined previously untreated patients with advanced esophageal squamous cell carcinoma (ESCC) who received four cycles of paclitaxel with carboplatin every 3 weeks. Toripalimab was infused intravenously every 3 weeks for 12 months, or until disease progression or intolerable toxicity. Radiotherapy that encompassed the primary lesions and metastases commenced in the third cycle. The median progression-free survival time was 9.8 months (95% confidence interval [CI]: 6.8-not estimable) in the intent-to-treat population, failing to meet the pre-specified primary endpoints. Secondary endpoints included an objective response rate of 45.5%, a disease control rate of 57.6%, and a median duration of response of 11.5 months (interquartile range, 6.4-15.0). The 1-year progression-free survival and overall survival rates were 41.9% (95% CI: 27.7-63.5) and 69.7% (95% CI: 55.7-87.3), respectively. Lymphopenia was the most frequent grade ≥3 adverse event (82%), and an esophageal fistula developed in three patients (9.1%). No treatment-related deaths occurred. In prespecified exploratory biomarker analysis, higher densities of CD8 + T cells, CD11c+ dendritic cells, and CD68+ macrophages correlated with improved tumor response and prognosis. Radiotherapy supplementation to first-line chemo-immunotherapy for treatment-naive advanced ESCC demonstrated some antitumor activity and manageable safety profiles, warranting further randomized controlled trials., (© 2024.

Importance: For patients with non-small cell lung cancer whose disease progressed while receiving EGFR tyrosine kinase inhibitor (EGFR-TKI) therapy, particularly third-generation TKIs, optimal treatment options remain limited., Objective: To compare the efficacy of ivonescimab plus chemotherapy with chemotherapy alone for patients with relapsed advanced or metastatic non-small cell lung cancer with the epidermal growth factor receptor (EGFR) variant., Design, Setting, and Participants: Double-blind, placebo-controlled, randomized, phase 3 trial at 55 sites in China enrolled participants from January 2022 to November 2022; a total of 322 eligible patients were enrolled., Interventions: Participants received ivonescimab (n = 161) or placebo (n = 161) plus pemetrexed and carboplatin once every 3 weeks for 4 cycles, followed by maintenance therapy of ivonescimab plus pemetrexed or placebo plus pemetrexed., Main Outcomes and Measures: The primary end point was progression-free survival in the intention-to-treat population assessed by an independent radiographic review committee (IRRC) per Response Evaluation Criteria in Solid Tumors version 1.1. The results of the first planned interim analysis are reported., Results: Among 322 enrolled patients in the ivonescimab and placebo groups, the median age was 59.6 vs 59.4 years and 52.2% vs 50.9% of patients were female. As of March 10, 2023, median follow-up time was 7.89 months. Median progression-free survival was 7.1 (95% CI, 5.9-8.7) months in the ivonescimab group vs 4.8 (95% CI, 4.2-5.6) months for placebo (difference, 2.3 months; hazard ratio [HR], 0.46 [95% CI, 0.34-0.62]; P < .001). The prespecified subgroup analysis showed progression-free survival benefit favoring patients receiving ivonescimab over placebo across almost all subgroups, including patients whose disease progressed while receiving third-generation EGFR-TKI therapy (HR, 0.48 [95% CI 0.35-0.66]) and those with brain metastases (HR, 0.40 [95% CI, 0.22-0.73]). The objective response rate was 50.6% (95% CI, 42.6%-58.6%) with ivonescimab and 35.4% (95% CI, 28.0%-43.3%) with placebo (difference, 15.6% [95% CI, 5.3%-26.0%]; P = .006). The median overall survival data were not mature; at data cutoff, 69 patients (21.4%) had died. Grade 3 or higher treatment-emergent adverse events occurred in 99 patients (61.5%) in the ivonescimab group vs 79 patients (49.1%) in the placebo group, the most common of which were chemotherapy-related. Grade 3 or higher immune-related adverse events occurred in 10 patients (6.2%) in the ivonescimab group vs 4 (2.5%) in the placebo group. Grade 3 or higher vascular endothelial growth factor-related adverse events occurred in 5 patients (3.1%) in the ivonescimab group vs 4 (2.5%) in the placebo group., Conclusions: Ivonescimab plus chemotherapy significantly improved progression-free survival with tolerable safety profile in TKI-treated non-small cell lung cancer., Trial Registration: ClinicalTrials.gov Identifier: NCT05184712.
