Background: The study is to evaluate the efficacy and safety of combined anlotinib and EGFR-tyrosine kinase inhibitors (TKIs) in patients with advanced non-small cell lung cancer (NSCLC) who had gradual, oligo, or potential progression after previous EGFR-TKIs treatment., Methods: We conducted an open-label, single-arm, multicenter, phase II trial in China. Eligible patients were 18-75 years old with histologically or cytologically confirmed NSCLC who were EGFR mutation positive and showed gradual, oligo, or potential progression after EGFR-TKIs. Anlotinib (12 mg/day) was administered orally for 2 weeks and then off 1 week in a 3-week cycle. EGFR-TKIs were continue used. The primary endpoint was progression-free survival (PFS). The secondary endpoints included 6- and 12-month PFS rate, objective response rate (ORR), disease control rate (DCR), overall survival (OS) and safety., Results: From July 2019 to December 2022, 120 patients were enrolled. The median PFS (mPFS) was 9.1 months (95% CI 6.8-11.7). The PFS rates at 6 and 12 months was 68.5% and 38.8% respectively. For 86 patients with first-line 1st /2nd generation EGFR-TKIs, the mPFS was 9.2 months (95% CI 6.7-12.6). For 32 patients with first-line 3rd generation EGFR-TKIs, the mPFS was 10.3 months (95% CI 6.1-13.3). Overall ORR and DCR were 6.7% (95% CI 2.9-12.7) and 87.5% (95% CI 80.2-92.8), respectively. 52.5% of patients had grade 3 or higher treatment-emergent adverse events (TEAEs)., Conclusion: Anlotinib in combination with continuation of EGFR-TKIs prolonged the clinical benefit of EGFR-TKIs, demonstrating favorable survival outcomes and manageable toxicity in NSCLC treated with EGFR-TKIs and had specific progression modes, such as gradual progression., Trial Registration: NCT04007835., Competing Interests: Declarations.

Background: Anti-programmed cell death 1 (PD-1) antibody combined with chemotherapy simultaneously is regarded as the standard treatment for patients with advanced non-small cell lung cancer (NSCLC) by current clinical guidelines. Different immune statuses induced by chemotherapy considerably affect the synergistic effects of the chemo-anti-PD-1 combination. Therefore, it is necessary to determine the optimal timing of combination treatment administration., Methods: The dynamic immune status induced by chemotherapy was observed in paired peripheral blood samples of patients with NSCLC using flow cytometry and RNA sequencing. Ex vivo studies and metastatic lung carcinoma mouse models were used to evaluate immune activity and explore the optimal combination timing. A multicenter prospective clinical study of 170 patients with advanced NSCLC was performed to assess clinical responses, and systemic immunity was assessed using omics approaches., Results: PD-1 expression on CD8 + T cells was downregulated on day 1 (D1) and D2, but recovered on D3 after chemotherapy administration, which is regulated by the calcium influx-P65 signaling pathway. Programmed cell death 1 ligand 1 expression in myeloid-derived suppressor cells was markedly reduced on D3. RNA sequencing analysis showed that T-cell function began to gradually recover on D3 rather than on D1. In addition, ex vivo and in vivo studies have shown that anti-PD-1 treatment on D3 after chemotherapy may enhance the antitumor response and considerably inhibit tumor growth. Finally, in clinical practice, a 3-day-delay sequential combination enhanced the objective response rate (ORR, 68%) and disease control rate (DCR, 98%) compared with the simultaneous combination (ORR=37%; DCR=81%), and prolonged progression-free survival to a greater extent than the simultaneous combination. The new T-cell receptor clones were effectively expanded, and CD8 + T-cell activity was similarly recovered., Conclusions: A 3-day-delay sequential combination might increase antitumor responses and clinical benefits compared with the simultaneous combination., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Purpose: Many cancer patients express interest in using herbal medicine during chemotherapy, but little is known about its benefits and risks. This study aimed to evaluate the effects of the Chinese herbal medicine JianPi-BuShen formula (JPBS) on adjuvant chemotherapy completion in colon cancer patients., Patients and Methods: This multi-center, phase III, randomized, placebo-controlled trial included patients with stage II (high risk for recurrence) and stage III colon cancer following surgery, planning to receive CAPOX (capecitabine and oxaliplatin) chemotherapy. Patients were randomized 1:1 to receive either JPBS or a placebo. The primary outcome was the completion rate of planned chemotherapy cycles. Secondary outcomes included relative dose intensity (RDI), chemotherapy-induced toxicities, quality of life (measured by the Edmonton Symptom Assessment System - ESAS), adverse events (AEs), and serious AEs (SAEs). Predefined subgroup analyses were performed by age (>65/≤65) and TNM stage (II/III)., Results: A total of 376 participants were analyzed, with a median age of 60.3 years; 56.9 % were male, and 67.6 % had stage III disease. Chemotherapy completion was significantly higher in the JPBS group than in the placebo group (63.0 % vs. 47.6 %, P = 0.003). Oxaliplatin RDI was also higher in the JPBS group (P = 0.049). Subgroup analyses showed JPBS significantly improved completion rates for stage II patients (73.0 % vs. 42.4 %, P = 0.001) and younger patients (66.9 % vs. 48.8 %, P = 0.004). JPBS reduced grade ≥ 2 vomiting (3.8 % vs. 6.4 %, P = 0.007) but increased grade ≥ 2 thrombocytopenia (16.2 % vs. 12.4 %, P = 0.012). Quality of life improved in stage II and younger patients., Conclusion: JPBS improved chemotherapy completion rates in stage II and younger colon cancer patients without compromising tolerability. Further research is needed to explore its mechanisms and long-term effects., Competing Interests: Declaration of Competing Interest All authors have no conflicts of interests to disclose., (Copyright © 2024 Elsevier Ltd.

The present study aimed to assess the efficacy and safety of immune checkpoint inhibitor (ICI)-based therapy in patients with metastatic breast cancer (MBC). Therefore, eligible patients with histologically confirmed MBC, treated with ICI-based therapy, were enrolled. The primary endpoint was progression-free survival (PFS) and the secondary endpoints included objective response rate (ORR), disease control rate (DCR), overall survival (OS) and safety. A total of 90 patients with MBC, treated with ICI-based therapy, with different treatment lines, were included in the present study. The median age was 50 years (range, 27-76). The predominant tumor subtypes were triple negative (53.3%) and luminal (31.1%) breast cancer. The majority of patients (61.1%) were heavily pretreated (lines of treatment, ≥3). Approximately half of the patients (46.7%) had ≥3 metastatic sites. The overall ORR was 36.7% (33/90 patients), while a DCR of 78.9% (71/90 patients) was also recorded. With a median follow-up of 16.0 months, the median PFS and OS were 4.9 months [95% confidence interval (CI), 3.8-6.1] and 13.9 months (95% CI, 9.5-18.2), respectively. Patients treated with ICIs as first-line therapy exhibited notable improvement, with a median PFS of 11.0 months (95% CI, 6.0-16.0) and a median OS of 24.3 months (95% CI, 11.4-37.2). In addition, the pretreatment blood platelet-to-lymphocyte ratio was an independent risk factor for PFS [hazard ratio (HR)=2.406; 95% CI, 1.325-4.370; P=0.004] and OS (HR=2.376; 95% CI, 1.059-5.328; P=0.036). The most common adverse events were nausea (44.4%), neutropenia (42.0%) and alanine aminotransferase/aspartate aminotransferase elevation (22.2%). Furthermore, three (3.3%) patients developed grade 1/2 immuno-related toxicity and recovered after supportive care. Overall, the present study suggested that the ICI-based therapy exhibited encouraging clinical outcomes with manageable toxicity in patients with MBC in real-world settings, with the most favorable efficacy in first-line treatment., Competing Interests: The authors declare that they have no competing interests., (Copyright: © 2024 Qian et al.)

The main cause of gastric cancer (GC)-related death is due to malignant cell unregulated distant metastasis and proliferation. Heterogeneous nuclear ribonucleoprotein A1 (hnRNPA1) has been shown to play an important role in carcinogenesis and the development of metastasis in several tumors. However, its downstream regulatory mechanism in GC is not well defined. Our study aims to investigate the function and regulatory mechanism of hnRNPA1 in GC. We analyzed the differential expression of hnRNPA1 in gastric cancer and paired adjacent normal tissues in the TCGA database. Kaplan-Meier analysis was employed for survival assessment. The expressions of hnRNPA1 in GC cells were measured by qRT-PCR and Western blot. Transwell assay, CCK8 and colony formation assay were used to detect the effect of hnRNPA1 on the metastasis and proliferation ability of GC cells. Additionally, Western blotting was performed to examine the expression of proteins related to the Wnt/β-catenin signaling pathway as well as epithelial-mesenchymal transition (EMT), while further investigations were carried out to explore potential regulatory mechanisms. The results showed that hnRNPA1 was highly expressed differentially in GC over normal gastric tissue. Knocking down hnRNPA1 inhibited the metastasis and proliferation of human gastric cancer cells. Overexpression of hnRNPA1 significantly enhanced the metastatic potential and proliferative capacity of human GC cells. Further mechanism exploration revealed that knocking down hnRNPA1 inhibited the Wnt/β-catenin signaling pathway and WNT1 inducible signaling pathway protein-2 (WISP2), an activator of the Wnt/β-catenin signaling pathway. Whereas overexpression of hnRNPA1 had the opposite effects. Our results demonstrated that hnRNPA1 promoted metastasis and proliferation of GC cells by activating Wnt/β-catenin signaling pathway via WISP2. hnRNPA1 may serve as a potential biomarker and novel therapeutic targets for GC., (© 2024.

Background: In the initial analysis of a pivotal phase 2 single-arm study (NCT03861156), befotertinib (D-0316) showed clinical benefit with a manageable safety profile in pretreated patients with EGFR T790M mutated non-small cell lung cancer (NSCLC), including those with brain metastases., Methods: Eligible patients received oral befotertinib of 50 mg (cohort A) or 75-100 mg (cohort B) once daily until disease progression, withdrawal of informed consent, or death. The primary endpoint for the initial analysis was objective response rate (ORR) assessed by an independent review committee. OS and safety were secondary endpoints. Herein, we present the final OS and safety data., Results: A total of 176 patients in cohort A and 290 patients in cohort B were finally enrolled. At data cutoff (May 31, 2023), the median duration of follow-up was 47.9 months (95 % CI: 47.1-48.3) in cohort A and 36.7 months (35.9-37.9) in cohort B. The median OS was 23.9 months (95 % CI: 21.1-27.2) in cohort A and 31.5 months (26.8-35.3) in cohort B. The median OS for patients with and without brain metastasis in cohort A was 18.6 months (95 % CI: 14.9-26.3) and 26.4 months (95 % CI: 23.0-29.0), respectively. In cohort B, these data was 23.0 months (95 % CI: 18.6-29.1) and 35.5 months (95 % CI: 29.3-NE), respectively. The safety profile of befotertinib remained consistent with previous data. Grade 3 or higher treatment-emergent adverse events were 38.1 % in the cohort A and 50.3 % in the cohort B, and 22.2 % and 31.7 % were related to the study drug., Conclusion: Befotertinib demonstrated a more profound OS benefit compared to other 3rd-generation EGFR TKI, despite that cross trial data comparison should be interpreted with caution. The safety profile was manageable and consistent with previously report data in pretreated patients with confirmed T790M mutation-positive NSCLC., 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: Garsorasib (D-1553; InventisBio, Shangai, China), a potent KRAS G12C inhibitor, has shown promising antitumour activity in patients with KRAS G12C -mutated (ie, Gly12Cys) non-small-cell lung cancer (NSCLC) in a phase 1 study. We report results from a phase 2 study conducted to evaluate the efficacy and safety of garsorasib in patients with locally advanced or metastatic KRAS G12C -mutated NSCLC., Methods: This open-label, multicentre, single-arm, phase 2 trial enrolled adult patients with KRAS G12C -mutated NSCLC who had previously been treated with platinum-based chemotherapy and immune checkpoint inhibitors from 43 hospitals in China. Participants received 600 mg garsorasib orally twice per day. Tumour assessments were performed at baseline, at the end of every two cycles (of 21 days) for the first eight cycles, and at the end of every three cycles thereafter. The primary endpoint was objective response rate (ORR) as assessed by an independent review committee (IRC) following the guidelines in Response Evaluation Criteria in Solid Tumours, version 1.1. Efficacy and safety were assessed in all patients who received at least one dose of garsorasib. This trial is registered at ClinicalTrials.gov, NCT05383898, and is active but no longer recruiting., Findings: From June 17, 2022, to May 17, 2023, of 225 patients screened for eligibility, 123 patients were enrolled and treated with garsorasib. Of these 123 participants, the median age was 64 years (IQR 59-68), 108 (88%) were male and 15 (12%) were female. At data cutoff (Nov 17, 2023), the median follow-up duration was 7·9 months (IQR 6·3-10·4), and 82 (67%) of 123 patients had discontinued treatment. The IRC-confirmed ORR was 50% (61 of 123 patients; 95% CI 41-59). 117 (95%) of 123 patients reported treatment-related adverse events, with 61 (50%) experiencing grade 3 or higher events. The most common types of adverse events of grade 3 or higher associated with garsorasib were hepatic and gastrointestinal events, including increased liver enzymes, such as aspartate aminotransferase (21 [17%] of 123 participants), alanine aminotransferase (19 [15%] of 123 participants), and gamma-glutamyltransferase (28 [23%] of 123 participants); nausea (2 [2%] of 123 participants); and vomiting (2 [2%] of 123 participants). No new safety signals were identified, and most of the adverse events were well managed., Interpretation: The results show that garsorasib has a high response rate, long duration of response, and an acceptable and manageable safety profile in patients with previously treated KRAS G12C -mutated NSCLC. Garsorasib potentially provides a promising treatment option for this patient population., Funding: InventisBio., Competing Interests: Declaration of interests ZL has received speaker fees from AstraZeneca, Roche, and Hansoh.

Since its initial report in 2015, CD47 has garnered significant attention as an innate immune checkpoint, raising expectations to become the next "PD-1." The optimistic early stages of clinical development spurred a flurry of licensing deals for CD47-targeted molecules and company mergers or acquisitions for related assets. However, a series of setbacks unfolded recently, starting with the July 2023 announcement of discontinuing the phase 3 ENHANCE study on Magrolimab plus Azacitidine for higher-risk myelodysplastic syndromes (MDS). Subsequently, in August 2023, the termination of the ASPEN-02 program, assessing Evorpacept in combination with Azacitidine in MDS patients, was disclosed due to insufficient improvement compared to Azacitidine alone. These setbacks have cast doubt on the feasibility of targeting CD47 in the industry. In this review, we delve into the challenges of developing CD47-SIRPα-targeted drugs, analyze factors contributing to the mentioned setbacks, discuss future perspectives, and explore potential solutions for enhancing CD47-SIRPα-targeted drug development., Competing Interests: Author WT is the founder of the company ImmuneOnco Biopharmaceuticals Shanghai Inc.

Over 944 thousand tonnes of shrimp carcasses are produced worldwide during the shrimp production cycle, and black soldier fly larvae (BSFL) are a potential solution for this shrimp carcass accumulation. In this study, we evaluated the performance of BSFL feeding on shrimp carcasses. Six combinations of wheat bran and shrimp carcass powder (with replacement increments of 20 %) and one whole shrimp carcasses treatment were tested. The bioconversion rate (27.15 ± 3.66 %; p = 0.001), crude protein (55.34 ± 1.27 %; p < 0.001), and crude lipid (14.37 ± 1.86 %; p = 0.007) values of BSFL reared on whole shrimp carcasses were significantly higher than those of BSFL reared on wheat bran. Increasing the shrimp carcass amount in the feeding media resulted in significant increases in BSFL docosahexaenoic acid (with the highest value occurring for BSFL reared on whole shrimp carcasses; 1.46 ± 0.09 %; p < 0.001). Conversely, BSFL docosahexaenoic acid was not detected for BSFL reared on wheat bran. The detected heavy metal concentrations in BSFL were below the limits of the published international guidelines for animal feed. In the obtained BSFL, Salmonella was not detected, and the mould count was <10 CFU/g. The total bacterial count (Lg transformation) of obtained BSFL ranged from 7.88 to 8.07 CFU/g, and no significant differences among all treatments (p = 0.424). Overall, this study demonstrates that BSFL-based bioconversion presents a resource recovery technology for converting shrimp carcasses into high-value nutritional biomass., 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.

Patients with triple-negative breast cancer (TNBC) have a poor prognosis due to the lack of effective molecular targets for therapeutic intervention. Here we found that the long noncoding RNA (lncRNA) MILIP supports TNBC cell survival, proliferation, and tumorigenicity by complexing with transfer RNAs (tRNA) to promote protein production, thus representing a potential therapeutic target in TNBC. MILIP was expressed at high levels in TNBC cells that commonly harbor loss-of-function mutations of the tumor suppressor p53, and MILIP silencing suppressed TNBC cell viability and xenograft growth, indicating that MILIP functions distinctively in TNBC beyond its established role in repressing p53 in other types of cancers. Mechanistic investigations revealed that MILIP interacted with eukaryotic translation elongation factor 1 alpha 1 (eEF1α1) and formed an RNA-RNA duplex with the type II tRNAs tRNALeu and tRNASer through their variable loops, which facilitated the binding of eEF1α1 to these tRNAs. Disrupting the interaction between MILIP and eEF1α1 or tRNAs diminished protein synthesis and cell viability. Targeting MILIP inhibited TNBC growth and cooperated with the clinically available protein synthesis inhibitor omacetaxine mepesuccinate in vivo. Collectively, these results identify MILIP as an RNA translation elongation factor that promotes protein production in TNBC cells and reveal the therapeutic potential of targeting MILIP, alone and in combination with other types of protein synthesis inhibitors, for TNBC treatment., Significance: LncRNA MILIP plays a key role in supporting protein production in TNBC by forming complexes with tRNAs and eEF1α1, which confers sensitivity to combined MILIP targeting and protein synthesis inhibitors., (©2024 The Authors; Published by the American Association for Cancer Research.)

Background: The initial phase II stuty (NCT03215693) demonstrated that ensartinib has shown clinical activity in patients with advanced crizotinib-refractory, anaplastic lymphoma kinase (ALK)-positive non-small cell lung cancer (NSCLC). Herein, we reported the updated data on overall survival (OS) and molecular profiling from the initial phase II study., Methods: In this study, 180 patients received 225 mg of ensartinib orally once daily until disease progression, death or withdrawal. OS was estimated by Kaplan‒Meier methods with two-sided 95% confidence intervals (CIs). Next-generation sequencing was employed to explore prognostic biomarkers based on plasma samples collected at baseline and after initiating ensartinib. Circulating tumor DNA (ctDNA) was detected to dynamically monitor the genomic alternations during treatment and indicate the existence of molecular residual disease, facilitating improvement of clinical management., Results: At the data cut-off date (August 31, 2022), with a median follow-up time of 53.2 months, 97 of 180 (53.9%) patients had died. The median OS was 42.8 months (95% CI: 29.3-53.2 months). A total of 333 plasma samples from 168 patients were included for ctDNA analysis. An inferior OS correlated significantly with baseline ALK or tumor protein 53 (TP53) mutation. In addition, patients with concurrent TP53 mutations had shorter OS than those without concurrent TP53 mutations. High ctDNA levels evaluated by variant allele frequency (VAF) and haploid genome equivalents per milliliter of plasma (hGE/mL) at baseline were associated with poor OS. Additionally, patients with ctDNA clearance at 6 weeks and slow ascent growth had dramatically longer OS than those with ctDNA residual and fast ascent growth, respectively. Furthermore, patients who had a lower tumor burden, as evaluated by the diameter of target lesions, had a longer OS. Multivariate Cox regression analysis further uncovered the independent prognostic values of bone metastases, higher hGE, and elevated ALK mutation abundance at 6 weeks., Conclusion: Ensartinib led to a favorable OS in patients with advanced, crizotinib-resistant, and ALK-positive NSCLC. Quantification of ctDNA levels also provided valuable prognostic information for risk stratification., (© 2024 The Authors.

Although antiprogrammed death 1 antibody plus chemotherapy has recently been approved for first-line esophageal squamous cell carcinoma (ESCC), antiprogrammed death-ligand 1 antibody may offer another combination option in this setting. In this multicenter, randomized, double-blinded phase 3 trial a total of 540 adults (aged 18-75 years) with unresectable, locally advanced, recurrent or metastatic ESCC and who had not received systemic treatment were enrolled. All patients were randomized at 2:1 to receive either sugemalimab (an anti-PD-L1 antibody; 1,200 mg) or placebo every 3 weeks for up to 24 months, plus chemotherapy (cisplatin 80 mg m - 2 on day 1 plus 5-fluorouracil 800 mg m - 2  day -1 on days 1-4) every 3 weeks for up to six cycles. At the prespecified interim analysis this study had met dual primary endpoints. With a median follow-up of 15.2 months, the prolongation of progression-free survival was statistically significant with sugemalimab plus chemotherapy compared with placebo plus chemotherapy (median 6.2 versus 5.4 months, hazard ratio 0.67 (95% confidence interval 0.54-0.82), P = 0.0002) as assessed by blinded independent central review. Overall survival was also superior with sugemalimab chemotherapy (median 15.3 versus 11.5 months, hazard ratio 0.70 (95% confidence interval 0.55-0.90, P = 0.0076). A significantly higher objective response rate (60.1 versus 45.2%) as assessed by blinded independent central review was observed with sugemalimab chemotherapy. The incidence of grade 3 or above treatment-related adverse events (51.3 versus 48.4%) was comparable between the two groups. Sugemalimab plus chemotherapy significantly prolonged progression-free survival and overall survival in treatment-naïve patients with advanced ESCC, with no unexpected safety signal.

Background: Distant metastasis is the major cause of lung adenocarcinoma (LUAD)-associated mortality. However, molecular mechanisms involved in LUAD metastasis remain to be fully understood. While the role of long non-coding RNAs (lncRNAs) in cancer development, progression, and treatment resistance is being increasingly appreciated, the list of dysregulated lncRNAs that contribute to LUAD pathogenesis is also rapidly expanding., Methods: Bioinformatics analysis was conducted to interrogate publicly available LUAD datasets. In situ hybridization and qRT-PCR assays were used to test lncRNA expression in human LUAD tissues and cell lines, respectively. Wound healing as well as transwell migration and invasion assays were employed to examine LUAD cell migration and invasion in vitro. LUAD metastasis was examined using mouse models in vivo. RNA pulldown and RNA immunoprecipitation were carried out to test RNA-protein associations. Cycloheximide-chase assays were performed to monitor protein turnover rates and Western blotting was employed to test protein expression., Results: The expression of the lncRNA LINC01559 was commonly upregulated in LUADs, in particular, in those with distant metastasis. High LINC01559 expression was associated with poor outcome of LUAD patients and was potentially an independent prognostic factor. Knockdown of LINC01559 diminished the potential of LUAD cell migration and invasion in vitro and reduced the formation of LUAD metastatic lesions in vivo. Mechanistically, LINC01559 binds to vimentin and prevents its ubiquitination and proteasomal degradation, leading to promotion of LUAD cell migration, invasion, and metastasis., Conclusion: LINC01559 plays an important role in LUAD metastasis through stabilizing vimentin. The expression of LINC01559 is potentially an independent prognostic factor of LUAD patients, and LINC01559 targeting may represent a novel avenue for the treatment of late-stage LUAD., (© 2024.

The combination of immune-checkpoint blockade with chemotherapy for the first-line treatment of advanced triple-negative breast cancer (TNBC) has generated mixed results. TORCHLIGHT is a randomized, double-blinded phase 3 trial evaluating the efficacy and safety of first-line toripalimab and nab-paclitaxel (nab-P) (n = 353; experimental arm) versus placebo and nab-P (n = 178; control arm) for the treatment of women with metastatic or recurrent TNBC. The primary end point was progression-free survival (PFS) assessed by a blinded independent central review in the PD-L1-positive and intention-to-treat populations. The secondary end points included overall survival and safety. Overall, 200 and 100 patients, in the toripalimab and placebo arm respectively had PD-L1-positive TNBC. At the prespecified interim analysis, a statistically significant improvement in PFS assessed by a blinded independent central review was demonstrated in the experimental arm in the PD-L1-positive population (median PFS 8.4 versus 5.6 months; hazard ratio (HR) = 0.65, 95% confidence interval (CI) 0.470-0.906, P = 0.0102). The median overall survival was 32.8 versus 19.5 months (HR = 0.62, 95% CI 0.414-0.914, P = 0.0148). Similar incidences of treatment-emergent adverse events (AEs) (99.2% versus 98.9%), grade ≥3 treatment-emergent AEs (56.4% versus 54.3%) and fatal AEs (0.6% versus 3.4%) occurred in the experimental and control arms. The addition of toripalimab to nab-P provided a significant improvement in PFS for PD-L1-positive patients with metastatic or recurrent TNBC with an acceptable safety profile.

Objective: DNA damage response (DDR) deficiency has emerged as a prominent determinant of tumor immunogenicity. This study aimed to construct a DDR-related immune activation (DRIA) signature and evaluate the predictive accuracy of the DRIA signature for response to immune checkpoint inhibitor (ICI) therapy in gastrointestinal (GI) cancer., Methods: A DRIA signature was established based on two previously reported DNA damage immune response assays. Clinical and gene expression data from two published GI cancer cohorts were used to assess and validate the association between the DRIA score and response to ICI therapy. The predictive accuracy of the DRIA score was validated based on one ICI-treated melanoma and three pan-cancer published cohorts., Results: The DRIA signature includes three genes ( CXCL10 , IDO1 , and IFI44L ). In the discovery cancer cohort, DRIA-high patients with gastric cancer achieved a higher response rate to ICI therapy than DRIA-low patients (81.8% vs. 8.8%; P < 0.001), and the predictive accuracy of the DRIA score [area under the receiver operating characteristic curve (AUC) = 0.845] was superior to the predictive accuracy of PD-L1 expression, tumor mutational burden, microsatellite instability, and Epstein-Barr virus status. The validation cohort demonstrated that the DRIA score identified responders with microsatellite-stable colorectal and pancreatic adenocarcinoma who received dual PD-1 and CTLA-4 blockade with radiation therapy. Furthermore, the predictive performance of the DRIA score was shown to be robust through an extended validation in melanoma, urothelial cancer, and pan-cancer., Conclusions: The DRIA signature has superior and robust predictive accuracy for the efficacy of ICI therapy in GI cancer and pan-cancer, indicating that the DRIA signature may serve as a powerful biomarker for guiding ICI therapy decisions., Competing Interests: No potential conflicts of interest are disclosed., (Copyright © 2024 Cancer Biology & Medicine.)

Importance: Gastric and gastroesophageal junction cancers are diagnosed in more than 1 million people worldwide annually, and few effective treatments are available. Sintilimab, a recombinant human IgG4 monoclonal antibody that binds to programmed cell death 1 (PD-1), in combination with chemotherapy, has demonstrated promising efficacy., Objective: To compare overall survival of patients with unresectable locally advanced or metastatic gastric or gastroesophageal junction cancers who were treated with sintilimab with chemotherapy vs placebo with chemotherapy. Also compared were a subset of patients with a PD ligand 1 (PD-L1) combined positive score (CPS) of 5 or more (range, 1-100)., Design, Setting, and Participants: Randomized, double-blind, placebo-controlled, phase 3 clinical trial conducted at 62 hospitals in China that enrolled 650 patients with unresectable locally advanced or metastatic gastric or gastroesophageal junction adenocarcinoma between January 3, 2019, and August 5, 2020. Final follow-up occurred on June 20, 2021., Interventions: Patients were randomized 1:1 to either sintilimab (n = 327) or placebo (n = 323) combined with capecitabine and oxaliplatin (the XELOX regimen) every 3 weeks for a maximum of 6 cycles. Maintenance therapy with sintilimab or placebo plus capecitabine continued for up to 2 years., Main Outcomes and Measures: The primary end point was overall survival time from randomization., Results: Of the 650 patients (mean age, 59 years; 483 [74.3%] men), 327 were randomized to sintilimab plus chemotherapy and 323 to placebo plus chemotherapy. Among the randomized patients, 397 (61.1%) had tumors with a PD-L1 CPS of 5 or more; 563 (86.6%) discontinued study treatment and 388 (59.7%) died; 1 patient (<0.1%) was lost to follow-up. Among all randomized patients, sintilimab improved overall survival compared with placebo (median, 15.2 vs 12.3 months; stratified hazard ratio [HR], 0.77 [95% CI, 0.63-0.94]; P = .009). Among patients with a CPS of 5 or more, sintilimab improved overall survival compared with placebo (median, 18.4 vs 12.9 months; HR, 0.66 [95% CI, 0.50-0.86]; P = .002). The most common grade 3 or higher treatment-related adverse events were decreased platelet count (sintilimab, 24.7% vs placebo, 21.3%), decreased neutrophil count (sintilimab, 20.1% vs placebo, 18.8%), and anemia (sintilimab, 12.5% vs placebo, 8.8%)., Conclusions and Relevance: Among patients with unresectable locally advanced or metastatic gastric and gastroesophageal junction adenocarcinoma treated with first-line chemotherapy, sintilimab significantly improved overall survival for all patients and for patients with a CPS of 5 or more compared with placebo., Trial Registration: ClinicalTrials.gov Identifier: NCT03745170.

Background/aim: Cervical cancer (CC) poses a significant threat to women's health and has a relatively poor prognosis due to local invasion and metastasis. It is, therefore, crucial to elucidate the molecular mechanisms of CC metastasis. SNHG3 has been implicated in various tumor metastasis processes, but its involvement in CC has not been thoroughly studied. Our study aimed to investigate the role of SNHG3 in metastasis and elucidate its underlying mechanisms in CC., Materials and Methods: LncRNA SNHG3 expression in CC tissues was analyzed using TCGA and GSE27469 databases. Normal cervical epithelial cells and CC cell lines were used to detect mRNA expression of SNHG3 via quantitative reverse transcription polymerase chain reaction (qRT-PCR). With RNA interference (RNAi) technology, antisense oligonucleotides (ASO) can act on HeLa cells to knockdown target gene expression. The influence of SNHG3 on cell migration and invasion were determined by wound healing and transwell assays. Transcriptome sequencing (RNA-seq) was used to seek abnormally expressed genes between SNHG3 knockdown cells and control cells. The expressions of epithelial-mesenchymal transition (EMT) and Wnt/β-catenin signaling related proteins were detected using western blot., Results: SNHG3 was obviously up-regulated in CC tissues and cell lines, and ectopic expression of SNHG3 was associated with lymph node metastasis of CC. Knockdown of SNHG3 significantly inhibited cell migration and invasion in CC. Further molecular mechanism studies showed that SNHG3 knockdown could down-regulate the expression of WNT1 Inducible Signaling Pathway Protein 2 (WISP2) so as to inhibit the activation of the Wnt/β-catenin signaling pathway, and regulated the expression of EMT-related markers, that promoted the protein expression of E-cadherin, as well as decreased the expression of N-cadherin and vimentin., Conclusion: SNHG3 appears to exert a pro-metastatic effect in CC, as evidenced by inhibition of cell migration and invasion upon SNHG3 knockdown. EMT also appears to be attenuated. Of interest is the down-regulation of WISP2 following SNHG3 knockdown leads to the inactivation of the Wnt/β-catenin signaling pathway., (Copyright © 2023, International Institute of Anticancer Research (Dr. George J.

Background: Befotertinib (D-0316) is a novel, selective oral third-generation epidermal growth factor receptor (EGFR) tyrosine-kinase inhibitor. This phase 3 trial compared the efficacy and safety of befotertinib with icotinib as a first-line treatment for patients with EGFR mutation-positive locally advanced or metastatic non-small-cell lung cancer (NSCLC)., Methods: This study was a multicentre, open-label, randomised, controlled phase 3 study at 39 hospitals in China. Eligible patients were 18 years of age or older, had histologically confirmed locally advanced or metastatic stage IIIB, IIIC, or IV unresectable NSCLC, and had confirmed exon 19 deletions or exon 21 Leu858Arg mutation. Patients were randomly assigned (1:1) via an interactive web response system to receive either oral befotertinib (75-100 mg once daily) or oral icotinib (125 mg three times per day) in 21-day cycles until disease progression or withdrawal criteria were met. Randomisation was stratified by type of EGFR mutation, CNS metastasis status, and gender, and participants, investigators, and data analysts were not masked to treatment allocation. The primary endpoint was independent review committee (IRC)-assessed progression-free survival in the full analysis set, which comprised all randomly assigned patients. All patients who received at least one dose of the study drug were included in safety analyses. This study was registered with ClinicalTrials.gov, NCT04206072, and the overall survival follow-up is still in progress., Findings: Between Dec 24, 2019, and Dec 18, 2020, 568 patients were screened, of whom 362 were randomly assigned to the befotertinib (n=182) or icotinib (n=180) group; all 362 patients were included in the full analysis set. Median follow-up was 20·7 months (IQR 10·2-23·5) in the befotertinib group and 19·4 months (10·3-23·5) in the icotinib group. Median IRC-assessed progression-free survival was 22·1 months (95% CI 17·9-not estimable) in the befotertinib group and 13·8 months (12·4-15·2) in the icotinib group (hazard ratio 0·49 [95% CI 0·36-0·68], p<0·0001). Grade 3 or higher treatment-related adverse events occurred in 55 (30%) of 182 patients in the befotertinib group and in 14 (8%) of 180 patients in the icotinib group. Treatment-related serious adverse events were reported in 37 (20%) patients in the befotertinib group and in five (3%) patients in the icotinib group. Two (1%) patients in the befotertinib group and one (1%) patient in the icotinib group died due to treatment-related adverse events., Interpretation: Befotertinib demonstrated superior efficacy compared with icotinib in first-line treatment for patients with EGFR mutation-positive NSCLC. Although serious adverse events were more common in the befotertinib than the icotinib arm, the safety profile of befotertinib was manageable overall., Funding: Betta Pharmaceuticals (China)., Translation: For the Chinese translation of the abstract see Supplementary Materials section., Competing Interests: Declaration of interests SL received research support from AstraZeneca, Hutchison, BMS, Heng Rui, Beigene and Roche, Hansoh, and Lilly Suzhou Pharmaceutical; received speaker fees from AstraZeneca, Roche, Hansoh, and Heng Rui Therapeutics; and served as an advisor and consultant of AstraZeneca, Pfizer, Boehringer Ingelheim, Hutchison MediPharma, Zai Lab, GenomiCare, Yuhan Corporation, Menarini, InventisBio, and Roche.

Docetaxel is one of the most commonly used drugs in prostate cancer (PCa) chemotherapy, but its therapeutic effect in PCa is usually limited due to its drug resistance. APOBEC3B is a DNA cytosine deaminase that can alter biological processes, including chemoresistance. APOBEC3B is upregulated in various cancers. However, the biological function and underlying regulation of APOBEC3B in PCa remain unclear. In this study, we explored the role of APOBEC3B in PCa chemoresistance and the molecular mechanism of its dysregulated expression. Our results revealed that APOBEC3B was upregulated in PCa docetaxel-resistant cells, while its knockdown significantly repressed cell proliferation and docetaxel resistance of PCa cells. Bioinformatics and luciferase report analysis showed that miR-138-5p targeted APOBEC3B. In addition, miR-138-5p overexpression impeded cell proliferation and docetaxel resistance in PCa, while miR-138-5p inhibitors reversed this process. Further studies showed that upregulation of APOBEC3B expression in docetaxel-resistant cells overexpressing miR-138-5p could desensitize PCa cells to docetaxel treatment. Taken together, miR-138-5p regulates PCa cell proliferation and chemoresistance by targeting the 3'-UTR of APOBEC3B, which may provide novel insights and therapeutic targets for the treatment of PCa., 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 © 2023.

Background: In the first interim analysis of the ORIENT-31 trial, compared with chemotherapy alone, sintilimab plus bevacizumab biosimilar IBI305 plus chemotherapy (pemetrexed and cisplatin) significantly improved progression-free survival in patients with EGFR-mutated non-squamous non-small-cell lung cancer (NSCLC) who progressed on EGFR tyrosine-kinase inhibitor treatment. However, the benefit of anti-PD-1 or PD-L1 antibody added to chemotherapy in this patient population remains unclear, with no prospective evidence from phase 3 trials globally. We report the results from the prespecified second interim analysis of progression-free survival between sintilimab plus chemotherapy and chemotherapy alone, the updated results of sintilimab plus IBI305 plus chemotherapy, and preliminary overall survival results., Methods: This double-blind, randomised, placebo-controlled, phase 3 trial was done at 52 centres across China and included patients aged 18-75 years with locally advanced or metastatic (stage IIIB, IIIC, or IV according to the American Joint Committee on Cancer, eighth edition) EGFR-mutated non-squamous NSCLC, disease progression after EGFR tyrosine-kinase inhibitor treatment (according to the Response Evaluation Criteria in Solid Tumours version 1.1 [RECIST 1.1]), and at least one measurable lesion (according to RECIST 1.1). Patients were randomly assigned (1:1:1), using an interactive web response system, to receive sintilimab (200 mg) plus IBI305 (15 mg/kg) plus pemetrexed (500 mg/m 2 ) and cisplatin (75 mg/m 2 ), sintilimab plus chemotherapy, or chemotherapy alone on day 1 of each 3-week cycle for four cycles, followed by maintenance therapy of sintilimab, IBI305, and pemetrexed. All study drugs were administered intravenously. The primary endpoint was progression-free survival in the intention-to-treat population assessed by an independent radiographic review committee. Data cutoff was March 31, 2022, unless otherwise specified. The study is registered at ClinicalTrials.gov, NCT03802240 (ongoing)., Findings: Between July 11, 2019, and March 31, 2022, 1011 patients were screened and 476 were randomly assigned (158 to the sintilimab plus IBI305 plus chemotherapy group, 158 to the sintilimab plus chemotherapy group, and 160 to the chemotherapy alone group). The median follow-up duration for progression-free survival was 12·9 months (IQR 8·2-17·8) in the sintilimab plus IBI305 plus chemotherapy group, 15·1 months (8·0-19·5) in the sintilimab plus chemotherapy group, and 14·4 months (9·8-23·8) in the chemotherapy alone group. Sintilimab plus chemotherapy significantly improved progression-free survival compared with chemotherapy alone (median 5·5 months [95% CI 4·5-6·1] vs 4·3 months [4·1-5·3]; hazard ratio [HR] 0·72 [95% CI 0·55-0·94]; two-sided p=0·016). Significant progression-free survival benefit was sustained with sintilimab plus IBI305 plus chemotherapy compared with chemotherapy alone (median 7·2 months [95% CI 6·6-9·3]; HR: 0·51 [0·39-0·67]; two-sided p<0·0001). As of data cutoff (July 4, 2022), the median overall survival was 21·1 months (95% CI 17·5-23·9) for sintilimab plus IBI305 plus chemotherapy (HR 0·98 [0·72-1·34]) and 20·5 months (15·8-25·3) for sintilimab plus chemotherapy group (HR 0·97 [0·71-1·32]) versus 19·2 months (15·8-22·4) for chemotherapy alone; after adjusting for crossover, the HR for sintilimab plus IBI305 plus chemotherapy to chemotherapy alone ranged from 0·79 (0·57-1·09) to 0·84 (0·61-1·15) and the HR for sintilimab plus chemotherapy to chemotherapy alone ranged from 0·78 (0·57-1·08) to 0·84 (0·61-1·16). The safety results were generally consistent with those in the first interim analysis; in particular, treatment-related adverse events of grade 3 or worse occurred in 88 (56%) of 158 patients in the sintilimab plus IBI305 plus chemotherapy group, 64 (41%) of 156 patients in the sintilimab plus chemotherapy group, and 79 (49%) of 160 patients in the chemotherapy alone group., Interpretation: This is the first prospective phase 3 trial to show the benefit of anti-PD-1 antibody plus chemotherapy in patients with EGFR-mutated NSCLC who progressed on treatment with tyrosine-kinase inhibitors. Compared with chemotherapy alone, sintilimab combined with pemetrexed and cisplatin showed significant and clinically meaningful improvement of progression-free survival with an optimal safety profile. Sintilimab plus IBI305 plus chemotherapy continued to show progression-free survival benefit compared with chemotherapy alone in this second interim analysis with an additional 8-month follow-up., Funding: National Natural Science Foundation of China, Shanghai Municipal Science & Technology Commission Research Project, and Innovent Biologics., Translation: For the Chinese translation of the abstract see Supplementary Materials section., Competing Interests: Declaration of interests SL reports receiving research support from AstraZeneca, Hutchison, Bristol Myers Squibb, Heng Rui Beigene, Roche, and Hansoh; receiving speaker fees from AstraZeneca, Roche, and Hansoh; and serving as an adviser and consultant for AstraZeneca, Pfizer, Hutchison MediPharma, ZaiLab, GenomiCare, Novarti, Yuhan Corporation, Menarini, Mirati Therapeutics Inc, Daiichi Sankyo, D3 Bio, Simcere, Takeda, and Roche.

Introduction: D-1553 (garsorasib) is a potent and selective oral KRAS G12C inhibitor. We report results from a phase I dose-escalation and dose-expansion study of D-1553 in patients with KRAS G12C-mutated NSCLC in multiple sites in the People's Republic of China., Methods: Patients with KRAS G12C-mutated NSCLC have administrated D-1553 600 mg orally once daily, 800 mg once daily, 1200 mg once daily, 400 mg twice a day, or 600 mg twice a day in dose escalation. In dose-expansion, all patients received 600 mg twice a day. The safety, pharmacokinetics, and efficacy of D-1553 were evaluated., Results: Among a total of 79 treated patients, 75 patients (94.9%) reported treatment-related adverse events with 30 patients experiencing grade 3 or 4 events (38.0%). Most of the adverse events were manageable and the patients tolerated the study treatment well. Among 74 patients assessable for efficacy analysis, 30 patients had a partial response and 38 had stable disease with a confirmed objective response rate (ORR) and disease control rate (DCR) of 40.5% and 91.9%, respectively. The median progression-free survival was 8.2 months, and the median duration of response was 7.1 months. Among 62 patients assessable for response at the recommended phase 2 dose, partial response occurred in 24 patients (ORR, 38.7%) and stable disease in 32 patients (DCR, 90.3%). The median progression-free survival and duration of response were 7.6 months and 6.9 months, respectively. In patients with brain metastasis, ORR and DCR were 17% and 100%, respectively., Conclusions: D-1553 represents a promising therapeutic option for patients with KRAS G12C-mutated NSCLC with a well-tolerated safety profile and encouraging antitumor activity., (Copyright © 2023 International Association for the Study of Lung Cancer.

This phase I/II trial characterized the tolerability, safety, and antitumor activities of unecritinib, a novel derivative of crizotinib and a multi-tyrosine kinase inhibitor targeting ROS1, ALK, and c-MET, in advanced tumors and ROS1 inhibitor-naive advanced or metastatic non-small cell lung cancer (NSCLC) harboring ROS1 rearrangements. Eligible patients received unecritinib 100, 200, and 300 mg QD, and 200, 250, 300, and 350 mg BID in a 3 + 3 design during dose escalation and 300 and 350 mg BID during expansion. Phase II trial patients received unecritinib 300 mg BID in continuous 28-day cycles until disease progression or unacceptable toxicity. The primary endpoint was the objective response rate (ORR) per independent review committee (IRC). Key secondary endpoints included intracranial ORR and safety. The ORR of 36 efficacy evaluable patients in the phase I trial was 63.9% (95% CI 46.2%, 79.2%). In the phase II trial, 111 eligible patients in the main study cohort received unecritinib. The ORR per IRC was 80.2% (95% CI 71.5%, 87.1%) and the median progression-free survival (PFS) per IRC was 16.5 months (95% CI 10.2, 27.0). Additionally, 46.9% of the patients who received recommended phase II dose of 300 mg BID experienced grade 3 or higher treatment-related adverse events. Treatment-related ocular disorders and neurotoxicity occurred in 28.1% and 34.4% of patients, respectively, but none was grade 3 or higher. Unecritinib is efficacious and safe for ROS1 inhibitor-naive patients with ROS1-positive advanced NSCLC, particularly patients with brain metastases at baseline, strongly supporting that unecritinib should become one of the standards of care for ROS1-positive NSCLC.ClinicalTrials.gov identifier: NCT03019276 and NCT03972189., (© 2023.

Background: Rezivertinib (BPI-7711) is a novel third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) which revealed the systematic and central nervous system (CNS) antitumor activities for EGFR T790M-mutated advanced NSCLC in previous clinical studies and is further analyzed here., Methods: Eligible patients from the previous phase I and phase IIb studies of rezivertinib were included for pooled analysis. Post-progressive patients who received a prescribed dosage (≥180 mg) of rezivertinib orally once daily were included in full analysis set (FAS), while those with stable, asymptomatic CNS lesions, including measurable and non-measurable ones at baseline were included in CNS full analysis set (cFAS). Patients with measurable CNS lesions were included in CNS evaluable for response set (cEFR). BICR-assessed CNS objective response rate (CNS-ORR), CNS disease control rate (CNS-DCR), CNS duration of response (CNS-DoR), CNS progression-free survival (CNS-PFS), and CNS depth of response (CNS-DepOR) were evaluated., Results: 355 patients were included in FAS, among whom 150 and 45 patients were included in cFAS and cEFR. This pooled analysis showed the CNS-ORR was 32.0% (48/150; 95% CI: 24.6-40.1%) and the CNS-DCR was 42.0% (63/150; 95% CI: 34.0-50.3%) in cFAS, while that in cEFR were 68.9% (31/45; 95% CI: 53.4-81.8%) and 100% (45/45; 95% CI: 92.1-100.0%). In cEFR, the median CNS-DepOR and the mean of CNS-DepOR were -52.0% (range: -100.0 to 16.1%) and -46.8% (95% CI: -55.5 to -38.1%). In cFAS, the median CNS-DoR and CNS-PFS were 13.8 (95% CI: 9.6-not calculable [NC]) and 16.5 (95% CI: 13.7-NC) months., Conclusions: Rezivertinib demonstrated encouraging clinical CNS efficacy among advanced NSCLC patients with EGFR T790M mutation and CNS metastases., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Michael Greco, Tingting Wang, and Anqi Zhou are employees of Beta Pharma, and all other authors declare no competing interests., (Copyright © 2023 Elsevier B.V.

Aim: Effective biomarkers for estimating glioma prognosis are deficient. Canonically, caspase-3 acts as an "apoptosis executioner". However, its prognostic role in glioma and mechanistic effects on prognosis remain unclear., Methods: With glioma tissue microarrays, the prognostic roles of cleaved caspase-3 and its association with angiogenesis were explored. Next, by analyzing the mRNA microarray data from the CGGA, the prognostic role of CASP3 expression and correlations between CASP3 and markers of glioma angiogenesis and proliferation were investigated. To biologically interpret the prognostic role of caspase-3 in glioma, the influence of caspase-3 on surrounding angiogenesis and glioma cell repopulation was investigated with an in vitro cell co-culture model, which comprises irradiated U87 cells and un-irradiated firefly luciferase (Fluc)-labeled HUVEC (HUVEC-Fluc) or U87 (U87-Fluc) cells. The over-expressed dominant-negative caspase-3 was used to suppress normal caspase-3 activity., Results: High levels of cleaved caspase-3 expression were associated with poor survival outcomes in glioma patients. Higher microvessel density was observed in patients with high levels of cleaved caspase-3 expression. By mining the microarray data in CGGA, it was revealed that higher CASP3 expression was found in glioma patients with lower Karnofsky Performance score, higher WHO grade, malignant histological subtype, wild-type IDH. Higher CASP3 expression indicated a worse survival rate in glioma patients. Patients with high CASP3 expression and negative IDH mutation showed the worst survival rate. Positive correlations were found between CASP3 and markers of tumor angiogenesis and proliferation. Subsequent data based on an in vitro cell co-culture model revealed that caspase-3 in irradiated glioma cells mediated pro-angiogenic and repopulation-promoting effects via regulating COX-2 signaling. With glioma tissue microarrays, high levels of COX-2 expression showed inferior survival outcomes in glioma patients. Glioma patients with high levels of cleaved caspase-3 and COX-2 expression showed the worst survival outcomes., Conclusion: This study innovatively identified an unfavorable prognostic role of caspase-3 in glioma. The pro-angiogenic and repopulation-prompting effects of caspase-3/COX-2 signaling may explain its unfavorable prognostic role and offer novel insights into therapy sensitization and curative effect prediction of glioma., (© 2023.

We sought to extend our observation of LncRNA ADAMTS9-AS1 and to specifically uncover its role on the stemness of lung adenocarcinoma (LUAD) cancer cells. ADAMTS9-AS1 was poorly expressed in LUAD. The high ADAMTS9-AS1 expression was positively associated with overall survival. ADAMTS9-AS1 overexpression attenuated the colony-forming capacity and reduced stem cell-like population of LUAD cancer stem cells (CSCs). Furthermore, ADAMTS9-AS1 overexpression increased E-cadherin expression in addition to the downregulated expressions of Fibronectin and Vimentin in LUAD spheres. In vitro results also confirmed the ADAMTS9-AS1's inhibitory effect on the growth of LUAD cells. Moreover, the antagonistic repression of miR-5009-3p levels with the expression of ADAMTS9-AS1 and NPNT was confirmed. Finally, ADAMTS9-AS1 overexpression curbed the increasing stemness of LUDA-CSC caused by NPNT silencing, thus leading to the suppression of LUAD progression in vitro. Conclusively, ADAMTS9-AS1 negatively controls the LUAD cancer cell stemness progression through regulating miR-5009-3p/NPNT axis., Competing Interests: Declaration of Competing Interest The authors declare that they have no conflict of interests., (Copyright © 2023.

Blueberry is the source of a variety of bioactive substances, including phenolic compounds, such as anthocyanins, pterostilbene, phenolic acids, etc. Several studies have revealed that polyphenols in blueberry have important bioactivities in maintaining health, such as antioxidant and anti-tumor activities, immune regulation, the prevention of chronic diseases, etc. Therefore, these phenolic compounds in blueberries have been widely used in the field of healthcare, and the extraction, isolation, and purification of phenolic compounds are the prerequisites for their utilization. It is imperative to systematically review the research progress and prospects of phenolic compounds present in blueberries. Herein, the latest progress in the extraction, purification, and analysis of phenolic compounds from blueberries is reviewed, which can in turn provide a foundation for further research and usage of blueberries.

Docetaxel is a first-line chemotherapy drug for castration-resistant prostate cancer (CRPC); yet, some CRPC patients develop docetaxel drug resistance. Cabazitaxel is approved in the post-docetaxel treatment setting. However, recent studies suggested cross-resistance between the development of drug resistance and current treatments. In this study, we used docetaxel-resistant cell lines DU145/DTX50 and PC-3/DTX30 to measure the responses to cabazitaxel. Our findings demonstrated that docetaxel resistance could lead to cross-resistance to cabazitaxel. After docetaxel-resistant cells were treated with cabazitaxel, transcriptome analysis was performed, and the results were analyzed in combination with survival analysis and correlation analysis with Gleason score to screen the cross-resistance genes. The continuously increased expression of kinesin family member 14 (KIF14) was identified as the main cause of cross-resistance to cabazitaxel in docetaxel-resistant cells. Silencing the expression of KIF14 could restore the sensitivity of resistant PCa cells to docetaxel and cabazitaxel, attenuate proliferation and promote apoptosis of the resistant PCa cells. Notably, the depressed expression of KIF14 inhibited the phosphorylation of Akt located downstream. In summary, KIF14 mediates the cross-resistance between docetaxel and cabazitaxel, and targeting KIF14 could be an effective measurement for reversing docetaxel or cabazitaxel chemotherapy failure or enhancing the anti-tumor effects of docetaxel or cabazitaxel., Competing Interests: Declaration of competing interest The authors declare that they have no conflicts of interest., (Copyright © 2023 The Authors.

Background: For breast cancer (BC) with sentinel lymph node micrometastases (SLNMs), there are limited data to guide the selection of postoperative adjuvant therapy. This study aimed to identify target populations who might benefit most from adjuvant therapy and examine prognostic factors among patients with T1-2N1miM0 BC with one or two SLNMs who underwent sentinel lymph node biopsy (SLNB) alone., Methods: There were 7,423 patients diagnosed with T1-2N1miM0 BC between 2010 and 2015, and patients with one or two SLNMs were extracted from the Surveillance, Epidemiology, and End Results database. All the patients underwent SLNB alone without further axillary lymph node dissection, and they were stratified according to adjuvant therapy. The statistical significance of categorical variables was analyzed using the χ 2 test. Univariable and multivariable Cox analyses were used to analyze characteristics predictive of Breast-cancer-specific survival and overall survival (OS). Kaplan-Meier methods with the log-rank test was analyzed to compare survival difference between the different treatments., Results: Adjuvant chemotherapy and radiotherapy improved 5-year OS rates. Multivariate analysis revealed that age ≥70 years, high grade, T2 stage, triple-negative subtype, and absence of radiotherapy were poor prognostic factors for OS. Patients who received breast-conserving surgery (BCS), and those with invasive ductal carcinoma (IDC), luminal A, luminal B, or basal-like subtype, and T1c or T2 stage benefited from adjuvant radiotherapy. Patients who received BCS, and those with IDC, luminal A subtype, and T1b, T1c, or T2 stage benefited from adjuvant chemotherapy., Conclusion: Our findings provide a clinical evaluation of treatment choice after surgery, which may help clinicians make individualized clinical decisions., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2023 Li, Liu, Wu, Zhu and Cang.)

Purpose: The current evaluation methods for tumor infiltrating lymphocytes (TILs), particularly CD8 + TILs, mainly rely on semiquantitative immunohistochemistry with high variability. We aimed to construct an individualized DNA methylation-based signature for CD8 + TILs (CD8 + MeTIL) that may characterize melanoma immune microenvironment and guide therapeutic selection., Methods: The transcriptome profiles and DNA methylation data of 457 melanoma patients from The Cancer Genome Atlas (TCGA) database were analyzed. Differential methylation analysis between groups with high and low CD8 + TILs was performed to select differentially methylated positions (DMPs) and define CD8 + MeTIL. The prognostic value of CD8 + MeTIL and its predictive value for immunotherapy response were investigated using multiple melanoma cohorts., Results: We successfully constructed the CD8 + MeTIL signature based on four DMPs. The survival analyses showed that higher CD8 + MeTIL score was associated with worse survival outcomes in TCGA-SKCM and GSE144487 cohorts. The ROC curve for the predictive analysis revealed that the survival prediction of CD8 + MeTIL score was superior compared with CD8 + TILs (CIBERSORT) and CD8B mRNA expression. Furthermore, we founded that tumors with higher CD8 + MeTIL score were marked with immunosuppressive characteristics, including low immune score and downregulated immune-related pathways. More importantly, the CD8 + MeTIL score showed a potential predictive value for the benefit from immunotherapy in two published cohorts. When combined CD8 + MeTIL with PD-L1 expression, the patient classification showed significantly different immunotherapy response rates and long-term survival outcomes., Conclusions: The CD8 + MeTIL signature might be as a novel method to evaluate CD8 + TILs and guide immunotherapy approaches., (© 2023.

Background: We investigated the impact of factors that influence TP53 mutations on the efficacy of EGFR-tyrosine kinase inhibitors and potential treatment strategies., Materials and Methods: Tumor samples were collected to screen gene mutations by next-generation sequencing, as well as the patients' baseline characteristics. The overall response to treatment with TKIs was evaluated based on interval computed tomography scans at each follow-up time point. A Fisher's exact test and log-rank test were used to determine the statistical differences in this study., Results: A total of 1134 clinical samples were collected from NSCLC patients, and TP53 mut was identified in 644 cases and EGFR mut in 622 cases. A low frequency of TP53 mut or more than 50% EGFR co-mutation rate were related to the prognosis of TKI-treated patients. In addition, TP53 mut in the region outside of the DB domain had the strongest correlation with TKI resistance, whereas various types of mutations in the DB domain only had an impact on PFS. A grouping study of EGFR-TKI-based treatment revealed that EGFR-TKIs with chemotherapy were associated with more significant survival benefits for patients with prognostic TP53 mut , whereas EGFR-TKI therapy was favorable for TP53 wt patients. Furthermore, TP53 mut could shorten the time to the relapse of postoperative patients, who will also likely respond well to EGFR-TKIs with chemotherapy., Conclusion: Various characteristics of TP53 mut affect the prognosis of TKI-treated patients to varying degrees. EGFR-TKIs with chemotherapy were benefit for patients' survival with prognostic TP53 mut , which provides an important reference for treatment management of EGFR mut patients., (Copyright © 2022.

The protooncoprotein N-Myc, which is overexpressed in approximately 25% of neuroblastomas as the consequence of MYCN gene amplification, has long been postulated to regulate DNA double-strand break (DSB) repair in neuroblastoma cells, but experimental evidence of this function is presently scant. Here, we show that N-Myc transcriptionally activates the long noncoding RNA MILIP to promote nonhomologous end-joining (NHEJ) DNA repair through facilitating Ku70-Ku80 heterodimerization in neuroblastoma cells. High MILIP expression was associated with poor outcome and appeared as an independent prognostic factor in neuroblastoma patients. Knockdown of MILIP reduced neuroblastoma cell viability through the induction of apoptosis and inhibition of proliferation, retarded neuroblastoma xenograft growth, and sensitized neuroblastoma cells to DNA-damaging therapeutics. The effect of MILIP knockdown was associated with the accumulation of DNA DSBs in neuroblastoma cells largely due to decreased activity of the NHEJ DNA repair pathway. Mechanistical investigations revealed that binding of MILIP to Ku70 and Ku80 increased their heterodimerization, and this was required for MILIP-mediated promotion of NHEJ DNA repair. Disrupting the interaction between MILIP and Ku70 or Ku80 increased DNA DSBs and reduced cell viability with therapeutic potential revealed where targeting MILIP using Gapmers cooperated with the DNA-damaging drug cisplatin to inhibit neuroblastoma growth in vivo. Collectively, our findings identify MILIP as an N-Myc downstream effector critical for activation of the NHEJ DNA repair pathway in neuroblastoma cells, with practical implications of MILIP targeting, alone and in combination with DNA-damaging therapeutics, for neuroblastoma treatment.

Background: Apatinib is approved in China for the treatment of advanced gastric adenocarcinoma that had progressed or relapsed after standard systemic chemotherapy treatments. However, the effectiveness of Apatinib under real-world condition has not been evaluated and the drug performance under ideal and controlled circumstances has not been validated. In fact, genetic factors, poor healthcare access, social economic status, comorbidities compliance and other factors play significant role in drug performance under "real-world" conditions. Real-world experience can help validate the safety and efficacy of apatinib., Methods: In this observational, prospective study we evaluated the safety and efficacy of Apatinib in patient treated in China. Between March 2018 and March 2019, a total of 943 patients with gastric cancer treated with Apatinib were enrolled. Response Evaluation Criteria in Solid Tumors, version 1.1 and Common Terminology Criteria for Adverse Events, version 4.0 were used to evaluate efficacy and adverse effects., Results: The median progression-free survival (PFS) was 5.65 months (5.22-6.05 months), and the median overall survival (OS) was 11.47 months (10.41-12.52 months). Apatinib in combination with more than two agents was superior to single agent apatinib in overall response rate (ORR) [18.18% vs. 9.43%, 95% confidence interval (CI): 1.03-5.90] and disease control rate (DCR) (82.82% vs. 77.87%, 95% CI: 1.21-2.59). Apatinib in combination with single agent chemotherapy was also superior to apatinib alone with DCR (86.29% vs. 77.87%, 95% CI: 1.47-2.99) irrespective of the dose (250 or 500 mg). In the patient cohort who received a starting dose of 250 mg, the DCRs of the combined treatment and monotherapy groups were 86.22% vs. 80.00% (95% CI: 1.18-3.09), respectively. The most common treatment-emergent adverse events were anemia, anorexia and thrombocytopenia (66.28%, 37.75%, 36.06%, respectively)., Conclusions: Efficacy of Apatinib in this observational study is promising and toxicities are manageable. Combination of Apatinib with chemotherapy agents has a higher response rate and better disease control at the expense of increased serious adverse events. Better OS can be achieved by receiving apatinib treatment earlier. As a supplement and further validation of explanatory randomized controlled trials, the real-world study reflects the real efficacy of apatinib in practical application., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://atm.amegroups.com/article/view/10.21037/atm-22-5995/coif).

Non-small cell lung cancer (NSCLC) is the most common type of malignant tumor of the lung with poor prognosis. Currently, there is still no effective strategy for diagnosing lung cancer from the perspective of multiple biomarkers containing both polar and nonpolar molecules. In order to explore the pathological changes of NSCLC at the endogenous molecule levels, and further establish the strategy for identifying and monitoring drug efficacy of NSCLC, targeted metabolomics and lipidomics studies were established with NSCLC patients. Polar metabolites including 21 amino acids, 7 purines, 6 tricarboxylic acid (TCA) cycle metabolites, and nonpolar lipids like phosphatidylcholine (PC), phosphatidylethanolamine (PE), lysophosphatidylcholine (LPC), lysophosphatidylethanolamine (LPE), sphingomyelin (SM), and ceramide (Cer), diacylglycerol (DG), triacylglycerol (TG), were quantitatively determined based on LC-MS/MS, taking into account their metabolism were significantly concerned with the occurrence of lung cancer in previous study. As a result, 14 polar metabolites and 16 lipids were prominently altered in the plasma of NSCLC patients, among which, after multivariate statistical analysis, LPC 18:0 (sn-2), L-Phenylalanine (Phe), oxaloacetic acid (OAA) and xanthine (XA) were screened out as potential small molecules and lipid biomarkers for NSCLC. Furthermore, a new strategy for formulating equation of NSCLC identification was proposed and clinical utility was successfully evaluated through Kangai injection treatment to NSCLC patients. Taking together, this study investigated the pathological changes of NSCLC from the perspective of endogenous polar and nonpolar molecules, and shed a light on identification of NSCLC., 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 © 2022 Elsevier B.V.

Introduction: Rezivertinib (BPI-7711) is a novel third-generation EGFR tyrosine kinase inhibitor (TKI) targeting both EGFR-sensitizing mutations and EGFR T790M mutation. This study aimed to evaluate the efficacy and safety of rezivertinib in patients with locally advanced or metastatic/recurrent EGFR T790M-mutated NSCLC., Methods: Patients with locally advanced or metastatic/recurrent NSCLC with confirmed EGFR T790M mutation who progressed after first-/second-generation EGFR TKI therapy or primary EGFR T790M mutation were enrolled. Patients received rezivertinib at 180 mg orally once daily until disease progression, unacceptable toxicity, or withdrawal of consent. The primary end point was objective response rate (ORR) assessed by blinded independent central review per Response Evaluation Criteria in Solid Tumors version 1.1. Secondary end points included disease control rate (DCR), duration of response, progression-free survival (PFS), overall survival, and safety. This study is registered with Clinical Trials.gov (NCT03812809)., Results: A total of 226 patients were enrolled from July 5, 2019, to January 22, 2020. By the data cutoff date on January 24, 2022, the median duration of follow-up was 23.3 months (95% confidence interval [CI]: 22.8-24.0). The ORR by blinded independent central review was 64.6% (95% CI: 58.0%-70.8%), and DCR was 89.8% (95% CI: 85.1%-93.4%). The median duration of response was 12.5 months (95% CI: 10.0-13.9), and median PFS was 12.2 months (95% CI: 9.6-13.9). The median overall survival was 23.9 months (95% CI: 20.0-not calculated [NC]). Among 91 (40.3%) patients with central nervous system (CNS) metastases, the median CNS PFS was 16.6 months (95% CI: 11.1-NC). In 29 patients with more than or equal to one brain target lesion at baseline, the CNS ORR and CNS DCR were 69.0% (95% CI: 49.2%-84.7%) and 100% (95% CI: 88.1%-100%), respectively. Time to progression of CNS was 16.5 months (95% CI: 9.7-NC). Of 226 patients, 188 (83.2%) had at least one treatment-related adverse event, whereas grade more than or equal to 3 occurred in 45 (19.9%) patients. No interstitial lung disease was reported., Conclusions: Rezivertinib was found to have promising efficacy and favorable safety profile for patients with locally advanced or metastatic/recurrent NSCLC with EGFR T790M mutation., (Copyright © 2022 International Association for the Study of Lung Cancer.

Introduction: Befotertinib (D-0316) is a novel, third-generation EGFR tyrosine kinase inhibitor (TKI). This study evaluated befotertinib in patients with locally advanced or metastatic NSCLC who developed an EGFR T790M mutation after progression on first- or second-generation EGFR TKI therapy., Methods: This was a single-arm, open-label, phase 2 study at 49 hospitals across mainland China. Patients with locally advanced or metastatic NSCLC harboring EGFR T790M mutations with disease progression after prior first- or second-generation EGFR TKI therapy received oral befotertinib of 50 mg (cohort A) or 75 to 100 mg (cohort B) once daily. The primary end point was objective response rate (ORR) assessed by an independent review committee in intention-to-treat population. This trial is registered with ClinicalTrials.gov, number NCT03861156., Results: A total of 176 patients and 290 patients were included in cohorts A (50 mg) and B (75-100 mg), respectively. At data cutoff (August 15, 2021), independent review committee-assessed ORR was 67.6% (95% confidence interval [CI]: 61.9%-72.9%) in cohort B. The investigator-assessed ORR was 54.0% (95% CI: 46.3%-61.5%) in cohort A and 65.9% (95% CI: 60.1%-71.3%) in cohort B. The median investigator-assessed progression-free survival was 11.0 (95% CI: 9.6-12.5) months in cohort A and 12.5 (95% CI: 11.1-13.8) months in cohort B. The median independent review committee-assessed progression-free survival in cohort B was 16.6 (95% CI: 15.0-not evaluable [NE]) months. The intracranial ORR was 26.7% (95% CI: 7.8%-55.1%) in cohort A by investigator assessment, while 57.1% (95% CI: 34.0%-78.2%) and 55.9% (95% CI: 37.9%-72.8%) in cohort B by investigator and independent review committee assessment, respectively. The median investigator-assessed intracranial progression-free survival was 16.5 (95% CI: 8.6-NE) months in cohort A, while the median intracranial progression-free survival was not evaluable in cohort B due to immature data regardless of investigator or independent review committee assessment. and NE (95% CI: 13.8-NE) in cohort B. The overall survival was immature. Grade 3 or higher treatment-related adverse events and treatment-related serious adverse events occurred in 20.5% and 11.4% of patients in cohort A and in 29.3% and 10.0% of patients in cohort B, respectively., Conclusions: Befotertinib of 75 to 100 mg has satisfying efficacy and manageable toxicity in patients with locally advanced or metastatic NSCLC harboring T790M mutation with resistance to first- or second-generation EGFR TKIs. A phase 3 randomized trial is underway (NCT04206072)., (Copyright © 2022 International Association for the Study of Lung Cancer. Published by Elsevier Inc. All rights reserved.)

Background: VEGF inhibitors can enhance the efficacy of immunotherapy. However, despite high initial response rates, almost all patients eventually develop treatment resistance to EGFR tyrosine-kinase inhibitors. We aimed to evaluate the efficacy and safety of sintilimab with or without IBI305 plus pemetrexed and cisplatin, compared with pemetrexed and cisplatin alone, for the treatment of patients with locally advanced or metastatic EGFR-mutated non-small-cell lung cancer (NSCLC) who had disease progression after receiving EGFR tyrosine-kinase inhibitor therapy., Methods: This randomised, double-blind, multicentre, phase 3 trial was conducted at 52 hospitals in China. Eligible participants were adults aged 18-75 years with locally advanced or metastatic NSCLC and EGFR mut who progressed after receiving a EGFR tyrosine-kinase inhibitor, had an Eastern Cooperative Oncology Group performance status of 0 or 1 with at least one measurable lesion, and an estimated life expectancy of at least 3 months. Participants were randomly assigned (1:1:1) to receive sintilimab (200 mg) plus IBI305 (15 mg/kg) plus pemetrexed (500 mg/m 2 ) and cisplatin (75 mg/m 2 ), sintilimab plus pemetrexed and cisplatin, or pemetrexed and cisplatin (chemotherapy alone) using block randomisation with stratification according to sex and presence or absence of brain metastases. All study drugs were administered intravenously on day 1 of each cycle, once every 3 weeks. Except for cisplatin, which was only given in the first four cycles, treatment was given for 24 months or until disease progression, intolerable toxic effects, withdrawal of consent, death, or other protocol-specified conditions, whichever occurred first. The primary endpoint was progression-free survival in the intention-to-treat population. We herein report the first planned interim analysis, with progression-free survival results for the comparison between sintilimab plus IBI305 plus chemotherapy versus chemotherapy alone. The progression-free survival results for the sintilimab plus pemetrexed and cisplatin group are immature and not reported here. This study is registered with ClinicalTrials.gov, NCT03802240 (recruiting)., Findings: Between July 11, 2019, and July 31, 2021, 936 patients were screened and 444 were randomly assigned (148 to the sintilimab plus IBI305 plus chemotherapy group, 145 to the sintilimab plus chemotherapy group, and 151 to the chemotherapy alone group). Data cutoff for this interim analysis was July 31, 2021. After a median follow-up of 9·8 months (IQR 4·4-13·3), progression-free survival was significantly longer in the sintilimab plus IBI305 plus chemotherapy group versus the chemotherapy alone group (median 6·9 months [95% CI 6·0-9.3] vs 4·3 months [4·1-5·4]; hazard ratio 0·46 [0·34-0·64]; p<0·0001). The most common grade 3 or 4 treatment-related adverse events were decreased neutrophil count (30 [20%] in the sintilimab plus IBI305 plus chemotherapy group vs 26 [18%] in the sintilimab plus chemotherapy group vs 27 [18%] in the chemotherapy alone group), decreased white blood cell count (17 [11%] vs 12 [8%] vs 13 [9%]), and anaemia (18 [12%] vs ten [7%] vs 15 [10%]). Potentially treatment-related deaths occurred in six patients (intestinal obstruction, gastrointestinal haemorrhage, and myelosuppression in one patient each, and three deaths of unknown cause) in the sintilimab plus IBI305 plus chemotherapy group, and in one patient in the chemotherapy alone group (unknown cause)., Interpretation: In this interim analysis, sintilimab plus IBI305 plus cisplatin and pemetrexed was generally efficacious and well tolerated in patients with EGFR-mutated NSCLC who progressed after receiving EGFR tyrosine-kinase inhibitor therapy., Funding: Innovent Biologics and the National Natural Science Foundation of China., Translation: For the Chinese translation of the abstract see Supplementary Materials section., Competing Interests: Declaration of interests SL reports research support from AstraZeneca, Hutchison, BMS, Hengrui Therapeutics, Beigene, Roche, Hansoh, and Lilly Suzhou Pharmaceutical; speaker fees from AstraZeneca, Roche, Hansoh, and Hengrui Therapeutics; and is an adviser and consultant for AstraZeneca, Pfizer, Boehringer Ingelheim, Hutchison MediPharma, ZaiLab, GenomiCare, Yuhan Corporation, Menarini, InventisBio, and Roche.

Objectives: In ORIENT-11, first-line sintilimab + pemetrexed-platinum significantly improved PFS compared with placebo + pemetrexed-platinum in patients with advanced metastatic nonsquamous non-small-cell lung cancer (AMnsqNSCLC). The study met the primary endpoint of PFS as of 15November2019. Here we report final survival analysis from ORIENT-11 (NCT03607539) using a 15September2021 data cutoff., Methods: Patients with treatment-naïve locally AMnsqNSCLC without sensitizing EGFR or ALK genomic tumor aberrations were randomly assigned to sintilimab + pemetrexed-platinum (n = 266) or placebo + pemetrexed-platinum (n = 131). Patients were stratified by PD-L1 expression, platinum-chemotherapy, and gender. Treatment continued until PD, unacceptable toxicity, or a maximum of 24 months. Patients in the placebo + pemetrexed-platinum arm could be sequenced to second-line sintilimab monotherapy, contingent upon PD. Response was assessed (RECISTv.1.1) by blinded independent radiographic review committee. Primary endpoint was PFS. OS was a secondary endpoint and defined from date of randomization to date of death due to any cause. Final OS analysis was defined as approximately 2 years after last patient randomized or when approximately 65 % of patients died, whichever first., Results: At data cutoff of final OS analysis, median study follow-up was 30.8 months. Of 397 patients, 243 OS events were observed (sintilimab + pemetrexed-platinum:151[57 %];placebo + pemetrexed-platinum:92 [70 %]). Of the patients in placebo + pemetrexed-platinum arm, 47 % crossed over to sintilimab monotherapy per protocol. Median OS was 24.2 months in sintilimab + pemetrexed-platinum arm and 16.8 months in placebo + pemetrexed-platinum arm (HR:0.65[95 % CI:0.50,0.85]). Estimated 2-year OS rates were 50 %(sintilimab + pemetrexed-platinum) and 32 %(placebo + pemetrexed-platinum). After adjusting for the crossover effect, OS treatment effect was more pronounced with HR 0.52 (95 % CI:0.38,0.69). OS benefit across all prespecified subgroups was largely consistent with that observed in the ITT population., Conclusions: In the ORIENT-11 final OS analysis, sintilimab + pemetrexed-platinum demonstrated improved OS compared to placebo + pemetrexed-platinum when administered as first-line therapy in AMnsqNSCLC without EGFR or ALK genomic tumor aberrations., (Copyright © 2022.

This paper reports a method to derive a novel class of 3D generalized thermostatted oscillators from a simple damped harmonic oscillator. Its detailed procedure is obtained through a mathematical derivation. Then, we propose an example system to show the effectiveness of the method. Furthermore, the numerical analysis is performed to investigate its rich conservative dynamics, including chaotic sea, hierarchical invariant tori, and the coexistence of chaotic seas and invariant tori with islands-around-islands hierarchy, even if there are three dissipative terms in the example system. To verify the existence of conservative chaos at the physical level, an analog circuit is presented to observe the existing conservative chaotic flows in National Instruments multisim. We finally provide two systems, which can produce conservative chaotic flows with more complicated topologies, and draw our conclusions.

Background: Camrelizumab plus apatinib shows encouraging antitumor activity and acceptable toxicity in chemotherapy-pretreated patients with advanced non-small cell lung cancer (NSCLC); however, clinical benefits from this combination regimen in NSCLC patients with EGFR mutations or ALK rearrangements (EGFR+/ALK+) have not been reported. We assessed the efficacy and safety of this combined regimen in pretreated patients with advanced NSCLC and defined EGFR/ALK status (EGFR+/ALK+) in a phase 1b/2 trial., Methods: Previously treated patients with advanced EGFR+/ALK+ NSCLC were enrolled and given camrelizumab 200 mg intravenously every 2 weeks plus apatinib at the recommended dose of 250 mg orally once daily. Patients harboring sensitive EGFR mutations or ALK fusion genes had received at least one EGFR/ALK TKI and a platinum-based chemotherapy regimen before the enrollment. The primary endpoint was objective response rate (ORR)., Results: All 43 enrolled patients comprised the efficacy and safety analysis population. The confirmed ORR was 18.6% (95% CI: 8.4-33.4%) and the clinical benefit response rate was 27.9% (95% CI: 15.3-43.7%). Median progression-free survival (PFS) was 2.8 months (95% CI: 1.9-5.5 months) and median overall survival was not reached (95% CI: 7.3 months-not reached), with a median follow-up period of 15.7 months (range, 0.5-24.4 months). The most common grade ≥3 treatment-related adverse events (TRAEs) were hypertension (16.3%), proteinuria (11.6%) and palmar-plantar erythrodysaesthesia syndrome (9.3%). No unexpected adverse events were recorded., Conclusions: Camrelizumab plus apatinib showed moderate antitumor activity and acceptable safety profile in previously treated patients with advanced NSCLC and EGFR or ALK genetic aberrations, which warranted further validation., Trial Registration: ClinicalTrials.gov identifier: NCT03083041.

Introduction: Camrelizumab, a humanized immunoglobulin G4-κ monoclonal antibody against programmed cell death protein 1, has exhibited antitumor activity and tolerability across various tumors, including lung cancers. We conducted this double-blind, randomized phase 3 trial to investigate the efficacy and safety of camrelizumab or placebo plus chemotherapy as first-line treatment for patients with advanced squamous NSCLC. The predictive value of circulating tumor DNA (ctDNA) dynamics was also analyzed., Methods: CameL-sq, a double-blind, randomized phase 3 trial (NCT03668496), was conducted in 53 centers in the People's Republic of China. A total of 389 patients with stage IIIB-IV squamous NSCLC were randomized (1:1) to receive 4 to 6 cycles of carboplatin plus paclitaxel with camrelizumab or placebo (every 3 wk), followed by maintenance therapy with camrelizumab or placebo. Peripheral blood ctDNA samples were collected at baseline and the time after two cycles of treatment., Results: Of 389 eligible patients, 193 patients allocated camrelizumab plus chemotherapy and 196 patients allocated placebo plus chemotherapy were included in the efficacy and safety analysis. The results revealed significantly prolonged progression-free survival (median, 8.5 vs. 4.9 mo; p <0.0001) and overall survival (median, not reached vs. 14.5 mo; p <0.0001) with camrelizumab-chemotherapy versus placebo-chemotherapy. No unexpected treatment immune-related adverse events were observed in both groups. Biomarker analysis revealed that ctDNA clearance after two cycles of treatment was independently associated with dramatically longer progression-free survival (p <0.0001) and overall survival (p <0.0001) in camrelizumab plus chemotherapy group., Conclusions: Our findings support camrelizumab plus chemotherapy as a first-line treatment option in advanced squamous NSCLC. On-treatment ctDNA dynamics exhibited the potency to predict the efficacy of camrelizumab plus chemotherapy., (Copyright © 2021 International Association for the Study of Lung Cancer.

Platinum-based chemotherapy is the standard first-line treatment for advanced esophageal squamous cell carcinoma (ESCC). In this phase 3 study (ClinicalTrial.gov: NCT03829969), 514 patients with treatment-naïve advanced ESCC were randomized (1:1) to receive toripalimab or placebo in combination with paclitaxel plus cisplatin (TP) every 3 weeks for up to 6 cycles, followed by toripalimab or placebo maintenance. At the prespecified final analysis of progression-free survival (PFS), a significant improvement in PFS is observed for the toripalimab arm over the placebo arm (hazard ratio [HR] = 0.58; 95% CI, 0.46-0.74; p < 0.0001). The prespecified interim analysis of overall survival (OS) also reveals a significant OS improvement for patients treated with toripalimab plus TP over placebo plus TP (HR = 0.58; 95% CI, 0.43-0.78; p = 0.0004). The incidences of grade ≥3 treatment-emergent adverse events are similar between the two arms. Toripalimab plus TP significantly improves PFS and OS in patients with treatment-naïve, advanced ESCC, with a manageable safety profile., Competing Interests: Declaration of interests X.L. is employed by Shanghai Junshi Biosciences.

The durable responses and favorable long-term outcomes are limited to a proportion of advanced melanoma patients treated with immune checkpoint inhibitors (ICI). Considering the critical role of antitumor immunity status in the regulation of ICI therapy responsiveness, we focused on the immune-related gene profiles and aimed to develop an individualized immune signature for predicting the benefit of ICI therapy. During the discovery phase, we integrated three published datasets of metastatic melanoma treated with anti-PD-1 (n = 120) and established an immune-related gene pair index (IRGPI) for patient classification. The IRGPI was constructed based on 31 immune-related gene pairs (IRGPs) consisting of 51 immune-related genes (IRGs). The ROC curve analysis was performed to evaluate the predictive accuracy of IRGPI with AUC = 0.854. Then, we retrospectively collected one anti-PD-1 therapy dataset of metastatic melanoma (n = 55) from Peking University Cancer Hospital (PUCH) and performed the whole-transcriptome RNA sequencing. Combined with another published dataset of metastatic melanoma received anti-CTLA-4 (VanAllen15; n = 42), we further validated the prediction accuracy of IRGPI for ICI therapy in two datasets (PUCH and VanAllen15) with AUCs of 0.737 and 0.767, respectively. Notably, the survival analyses revealed that higher IRGPI conferred poor survival outcomes in both the discovery and validation datasets. Moreover, correlation analyses of IRGPI with the immune cell infiltration and biological functions indicated that IRGPI may be an indicator of the immune status of the tumor microenvironment (TME). These findings demonstrated that IRGPI might serve as a novel marker for treating of melanoma with ICI, which needs to be validated in prospective clinical trials., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Yan, Wu, Yu, Kong and Cang.)

β-cyclodextrin has a unique annular hollow ultrastructure that allows encapsulation of various poorly water-soluble drugs in the resulting cavity, thereby increasing drug stability. As a bioactive molecule, the metabolism of β-cyclodextrin is mainly completed by the flora in the colon, which can interact with API. In this study, understanding the in vivo fate of β-cyclodextrin, a LC-MS/MS method was developed to facilitate simultaneous quantitative analysis of pharmaceutical excipient β-cyclodextrin and API dextromethorphan hydrobromide. The established method had been effectively used to study the pharmacokinetics, tissue distribution, excretion, and metabolism of β-cyclodextrin after oral administration in rats. Results showed that β-cyclodextrin was almost wholly removed from rat plasma within 36 h, and high concentrations of β-cyclodextrin distributed hastily to organs with increased blood flow velocities such as the spleen, liver, and kidney after administration. The excretion of intact β-cyclodextrin to urine and feces was lower than the administration dose. It can be speculated that β-cyclodextrin metabolized to maltodextrin, which was further metabolized, absorbed, and eventually discharged in the form of CO 2 and H 2 O. Results proved that β-cyclodextrin, with relative low accumulation in the body, had good safety. The results will assist further study of the design and safety evaluation of adjuvant β-cyclodextrin and promote its clinical development.

Background: Camrelizumab plus chemotherapy significantly prolonged progression-free survival (PFS) and overall survival (OS) compared to chemotherapy alone as first-line treatment in advanced lung squamous cell carcinoma (LUSC) in the phase III trial (CameL-sq), which has become an option of standard-of-cares for Chinese patients with advanced LUSC. However, the predictive biomarkers remain unknown., Methods: Tumor tissue samples at baseline, and peripheral blood samples at baseline (pretreatment) and after two cycles of treatment (on-treatment) were prospectively collected from 270 LUSC patients from the CameL-sq study. Blood tumor mutation burden (bTMB) and its dynamics were analyzed to explore their predictive values., Results: Pretreatment bTMB was not associated with objective response, PFS and OS in camrelizumab or placebo plus chemotherapy groups. Low on-treatment bTMB was associated with significantly better objective response (73.8% vs 27.8%, P < 0.001), PFS (median, 9.1 vs 4.1 months; P < 0.001) and OS (median, not reached vs 8.0 months; P < 0.001) in camrelizumab plus chemotherapy group whereas it did not correlate with objective response and PFS in chemotherapy alone group. Importantly, on-treatment bTMB level could discriminate patients of initially radiological stable disease who would long-term benefit from camrelizumab plus chemotherapy (low vs high, median OS, 18.2 vs 7.8 months; P = 0.001). Combing on-treatment bTMB and its dynamics improved the ability for predicting the efficacy of camrelizumab plus chemotherapy., Conclusion: On-treatment bTMB together with its dynamics could serve as a predictive biomarker for camrelizumab plus chemotherapy in patients with advanced LUSC., Trial Registration: ClinicalTrials.gov identifier: NCT03668496., (© 2021.

Hepatocellular carcinoma (HCC) is the fifth most common cancer and the second most common cause of cancer-related deaths worldwide. As immune response failure is the main factor in the occurrence and poor prognosis of HCC, our study aimed to develop an immune-associated molecular occurrence and prognosis predictor (IMOPP) of HCC. To that end, we discovered a 4-gene immune-associated gene signature: C-C motif chemokine ligand 14 ( CCL14 ), kallikrein B1 ( KLKB1 ), vasoactive intestinal peptide receptor 1 ( VIPR1 ), and cluster of differentiation 4 ( CD4 ). When tested on three cohorts as an immune-associated molecular occurrence predictor (IMOP), it had high sensitivity, specificity, and area under the receiver operating characteristics curve. When tested as an immune-associated molecular prognosis predictor (IMPP), it stratified the HCC prognosis for overall survival (Kaplan-Meier analysis, log rank P = 0.0016; Cox regression, HR = 1.832, 95% CI = 1.173-2.859, P = 0.008) and disease-free survival (Kaplan-Meier analysis, log rank P = 0.0227). IMPP also significantly correlated with the clinicopathological characteristics of HCC; integrating it with clinicopathological characteristics improved the accuracy of a nomogram for overall survival prediction (C-index: 0.7097 vs. 0.6631). In HCC tumor microenviroments, the proportion of CD8 + T cells significantly differed between IMOP-stratified groups. We conclude that IMOPP can potentially predict the occurrence of HCC in high-risk populations and improve prognostic accuracy by providing new biomarkers for risk stratification. In addition, we believe that the IMOP mechanism may be related to its effect on the proportion of CD8 + T cells in tumor-infiltrating lymphocytes.

Introduction: Sintilimab plus chemotherapy significantly prolonged progression-free survival (PFS) compared with chemotherapy alone in nonsquamous NSCLC in the ORIENT-11 study. Updated overall survival (OS) and PFS data and corresponding biomarker analyses are reported here., Methods: In this study, a total of 397 patients with previously untreated, locally advanced or metastatic nonsquamous NSCLC were assigned to sintilimab plus chemotherapy combination treatment (combo) group or placebo plus chemotherapy treatment group. The patients were stratified by programmed death-ligand 1 (PD-L1) expression levels. Immune signature profiles from tumor RNA sequencing and PD-L1 immunohistochemistry were correlated with clinical outcome to identify predictive biomarkers., Results: As of January 2021, with median follow-up of 22.9 months, median OS was significantly improved in the combo group compared with the placebo plus chemotherapy treatment group (not reached versus 16.8 mo; hazard ratio [HR] = 0.60, 95% confidence interval [CI]: 0.45-0.79, p = 0.0003). High or medium immune cell infiltration was strongly associated with improved PFS in the combo group, in contrast to absent or low immune cell infiltration, which suggests that chemotherapy could not prime "immune deserts" to obtain benefit from programmed cell death protein-1 inhibition. In particular, high major histocompatibility complex (MHC) class II presentation pathway expression was significantly correlated with prolonged PFS (HR = 0.32, 95% CI: 0.19-0.54, p < 0.0001) and OS (HR = 0.36, 95% CI: 0.20-0.64, p = 0.0005) in the combo group. Importantly, patients with low or absent PD-L1 but high MHC class II expression could still benefit from the combo treatment. In contrast, MHC class I antigen presentation pathway was less relevant in this combination setting., Conclusions: The addition of sintilimab to chemotherapy resulted to significantly longer OS in nonsquamous NSCLC. Expression of MHC class II antigen presentation pathway could identify patients benefiting most from this combination., (Copyright © 2021 International Association for the Study of Lung Cancer.

Background: Lung cancer remains the leading cause of mortality from malignant tumors, non-small cell lung cancer (NSCLC) accounts for the majority of lung cancer cases, and individualized diagnosis and treatment is an effective trend. The individual characteristics of different traditional Chinese medicine (TCM) syndromes of NSCLC patients may be revealed by highly specific molecular profiles., Methods: In this study, 10 NSCLC patients with Qi deficiency and Yin deficiency (QDYD) syndrome and 10 patients with Qi deficiency of lung-spleen (QDLS) syndrome in TNM stage III-IV as well as 10 healthy volunteers were enrolled. Aiming at the varied syndromes of NSCLC patients with "Yin deficiency" as the main difference, a proteomics research based on data-independent acquisition (DIA) was developed. Of the dysregulated proteins in NSCLC patients, lipid metabolism was significantly enriched. Thereafter, nontargeted lipidomics research based on UPLC-Q-TOF/MS was performed in 16 patients, with 8 individuals randomly selected from each syndrome group. Furthermore, the considerably different characteristics between the syndromes and pathological mechanisms of NSCLC were screened by statistical and biological integrations of proteomics and lipidomics and the differential metabolic pathways of the two similar syndromes were further explored. Besides, lipids biomarkers were verified by a clinically used anticancer Chinese medicine, and the level of key differential proteins in the two syndromes was also validated using ELISA., Results: The results showed that glycerophospholipid metabolism, sphingolipid metabolism, glycolipid metabolism, and primary bile acid biosynthesis were altered in NSCLC patients and that glycerophospholipid metabolism was significantly changed between the two syndromes in lipidomics analysis. Among the proteins and lipids, ALDOC and lysophosphatidylcholine (LPCs) were revealed to have a strong relationship by statistical and biological integration analysis, and could effectively distinguish QDLS and QDYD syndromes. Notably, the patients with different syndromes had the most typical metabolic patterns in glycerophospholipid metabolism and glycolysis, reflecting the differences in the syndromes dominated by "Yin deficiency"., Conclusions: ALDOC and LPCs could be employed for the differentiation of NSCLC patients with QDLS and QDYD syndromes, and "Yin deficiency" might be associated with glycerophospholipid metabolism and glycolysis pathway. The results provided a theoretical basis for "Syndrome differentiation" in TCM diagnosis. Moreover, the developed integrated strategy could also provide a reference for individualized diagnosis and treatment of other diseases., (© 2021. The Author(s).)
