Background: In resectable gastric/gastroesophageal junction adenocarcinoma, microsatellite instability-high (MSI-H) confers improved survival, but limited benefit from chemotherapy. Immunotherapy may eliminate the need for chemotherapy or surgery., Patients and Methods: INFINITY is a multicenter, multicohort phase II trial (NCT04817826) investigating in cohort 1 the activity and safety of tremelimumab + durvalumab (T300/D) as neoadjuvant treatment of mismatch repair deficient/MSI-H, resectable gastric/gastroesophageal junction adenocarcinoma. Primary endpoint was pathologic complete response (pCR) rate; Secondary endpoints: progression-free survival (PFS), overall survival (OS), quality of life, and translational analyses. In cohort 2, the activity and safety of T300/D was explored as definitive treatment in patients achieving clinical complete response (cCR). Primary endpoint was 2-year cCR rate, and secondary endpoints were PFS, OS, quality of life, gastrectomy-free survival and translational analyses., Results: In cohort 1, 18 patients were recruited and 15 evaluable. pCR and major pathologic response-pCR were 60% and 80%, respectively. Since pCR rate in T4 tumors was 17%, this subgroup of patients was excluded from enrollment in cohort 2. At 28.1 months median follow-up, 24-month gastric cancer-specific PFS and OS rates were 85% and 92%, respectively. In cohort 2, 18 patients were enrolled and 17 assessable, and 13 had cCR and started non-operative management. At 11.5 months median follow-up, one patient had local regrowth and underwent salvage surgery; 12-month gastrectomy-free survival was 64.2%., Conclusions: The INFINITY study provided promising activity results of a chemo-free T300/D combination regimen as preoperative treatment in mismatch repair deficient/MSI gastric/gastroesophageal junction adenocarcinoma and the first available feasibility results of a non-operative management strategy in this disease setting, worthy of further validation in larger cohorts., (Copyright © 2024 The Author(s).

Background: Paclitaxel plus ramucirumab is recommended as a second-line treatment regimen in patients with advanced HER2-negative gastric or gastro-oesophageal junction cancer. We aimed to assess whether switch maintenance or early second-line therapy with paclitaxel plus ramucirumab improved outcomes compared with continuation of oxaliplatin and fluoropyrimidine doublet chemotherapy as a first-line strategy., Methods: ARMANI was a multicentre, open-label, randomised, phase 3 trial done in 31 hospitals in Italy. We enrolled patients aged 18 years or older with an Eastern Cooperative Oncology Group performance status of 0 or 1 and locally advanced unresectable or metastatic HER2-negative gastric or gastro-oesophageal junction cancer, who had disease control after 3 months of FOLFOX (leucovorin, fluorouracil, and oxaliplatin) or CAPOX (capecitabine and oxaliplatin). Patients were randomly assigned (1:1) to either paclitaxel 80 mg/m 2 on days 1, 8, and 15 plus ramucirumab at 8 mg/kg on days 1 and 15 every 28 days intravenously (switch maintenance group) or continuation of oxaliplatin-based doublet chemotherapy (FOLFOX or CAPOX) for an additional 12 weeks, followed by fluoropyrimidine monotherapy maintenance (control group). Randomisation was stratified by previous gastrectomy (no vs yes), peritoneal carcinomatosis (yes vs no), and primary tumour location (gastro-oesophageal junction vs gastric). Treatment group allocation was done using a web-based system with a minimisation algorithm implementing a random component. The primary endpoint was progression-free survival, analysed on an intention-to-treat basis. The safety population included patients who received at least one dose of the study treatment. This study is registered with ClinicalTrials.gov, NCT02934464, and is complete., Findings: Between Jan 1, 2017, and Oct 2, 2023, 280 patients were randomly assigned to receive paclitaxel plus ramucirumab (switch maintenance group; n=144) or to continue FOLFOX or CAPOX (control group; n=136). All patients were White. 180 (64%) of 280 patients were male and 100 (36%) were female. At a median follow-up of 43·7 months (IQR 24·0-57·9), 253 (90%) of 280 patients had a progression-free survival event: 131 (91%) of 144 patients in the switch maintenance group and 122 (90%) of 136 patients in the control group. Median progression-free survival was 6·6 months (95% CI 5·9-7·8) in the switch maintenance group and 3·5 months (2·8-4·2) in the control group (HR 0·61, 95% CI 0·48-0·79; p=0·0002). The assumption of proportional hazards was violated; in an analysis of 24-month restricted mean survival time, restricted mean progression-free survival was 8·8 months (95% CI 7·7-9·9) in the switch maintenance group and 6·1 months (5·0-7·2) in the control group (p=0·0010). The most frequent grade 3-4 treatment-related adverse events were neutropenia (37 [26%] patients in the switch maintenance group vs 13 [10%] patients in the control group), peripheral neuropathy (eight [6%] vs nine [7%]) and arterial hypertension (nine [6%] vs none). Serious adverse events occurred in 28 (20%) of 141 patients in the experimental group and 15 (11%) of 135 patients in the control group; these events were treatment-related in two (1%) patients in the switch maintenance group (pulmonary embolism) and two (1%) patients in the control group (mucositis and anaemia). No treatment-related deaths occurred., Interpretation: Paclitaxel and ramucirumab switch maintenance could be a potential treatment strategy in patients with advanced HER2-negative gastric or gastro-oesophageal junction cancer who are not eligible for immunotherapy or targeted agents., Funding: Partly funded by Eli Lilly., Competing Interests: Declaration of interests SL reports participation in advisory boards for Amgen, Astellas, AstraZeneca, Bayer, Bristol-Myers Squibb, Daiichi Sankyo, GSK, Incyte, Lilly, Merck Serono, MSD, Servier, Takeda, Rottapharm, and Beigene; personal honoraria as invited speaker from Amgen, AstraZeneca, Bristol-Myers Squibb, Incyte, GSK, Lilly, Merck Serono, MSD, Pierre Fabre, Roche, and Servier; and research funding (to their institution) from Amgen, Astellas, AstraZeneca, Bayer, Bristol-Myers Squibb, Daichii Sankyo, Hutchinson, Incyte, Merck Serono, Mirati, MSD, Pfizer, Roche, and Servier.

Introduction: The discovery of oncogenic mutations that drive the growth and progression of Non-small-cell lung cancer (NSCLC) led to the development of a range of molecular targeted therapies. Tyrosine kinase inhibitors (TKIs) improve the overall outcome of patients with oncogene addicted NSCLC, ensure a better compliance to treatment and few side effects compared to traditional chemotherapy. However, the treatment is still completely "drug-centric", in a population of patients who usually survive for a long time and desire to regain their quality of life. Despite an extensive literature on the importance of complementary treatments and lifestyle promotion, the guidelines on physical exercise are general and usually refer to the entire lung cancer pathology., Methods and Objectives: EXcellenT is an Italian monocentric randomized prospective study enrolling 40 patients diagnosed with oncogene-addicted advanced NSCLC in active treatment with TKIs. Patients will be randomized (1:1 ratio) to an 'interventional' or a 'control' group. In the interventional arm (arm A), participants will receive a 3-month multicomponent personalized physical activity prescription combining a supervised coaching program at the training center and an app-based physical activity schedule at patients home. In the control group (arm B) patients will receive a fitness professional-guided montly session that will result in an unsupervised home-based physical activity counselling. Prospective collection of blood metabolome and immune phenotypes will be performed to investigate the integration with genetic alterations that drive the patient's disease. The overall aim of the project is to evaluate if a tailored physical program may have a significant impact on quality of life and performances of this specific homogeneous subgroup of patients. The exploratory goal is to elucidate a potential link between metabolites, immune parameters and genetic deregulations and how this interplay may be influenced by physical exercise., Conclusion: EXcellent trial aims to propose a new approach to personalized medicine in the specific subgroup of oncogene-addicted NSCLC patients, where targeted therapy is integrated with an equally tailored physical activity program. The homogeneity of this cancer population will provide insights on the influence of exercise on metabolism and immunity during treatment with TKIs., Competing Interests: Disclosure The authors have stated that they have no conflicts of interest., (Copyright © 2024.

Background: Rectal cancer (RC) commonly affects older patients. Total Neoadjuvant Therapy (TNT) has been introduced to improve local and systemic control of RC. The aim was to present real-world data of older patients receiving TNT followed by surgery after a frailty assessment and verify feasibility and safety of this approach., Methods: This was a single-center retrospective study which enrolled all patients ≥70 years of age with RC who underwent TNT followed by surgery between November 2017 and April 2022. Data regarding cancer characteristics, neoadjuvant chemoradiotherapy (CRT), and toxicity were recorded. All patients underwent surgery 12-16 weeks after the end of therapy. Intra- and postoperative outcomes were recorded. Pre- and postoperative functional evaluation was carried out., Results: Fifteen patients were enrolled. Mean age was 74 (70-81) years. Mean distance of the tumor from the anal verge was 5.2 cm. Fourteen patients had positive nodes (93.3%), 11 (73.3%) showed involvement of the circumferential margin (CRM+) and 10 (66.6%) had extramural vascular invasion (EMVI+). Ten patients (66.6%) received mFOLFOX-6 and 5 CAPOX (33.3%) followed by CRT. After CRT, positive nodes were reported in 4 cases (26.6%), CRM+ in 4 (26.6%), and EMVI+ in 1 (6.6%). Transanal total mesorectal excision (taTME) was performed in all cases. Median operative time was 280 min (110-420). Median length of stay was 4 days (3-29). One Clavien-Dindo grade 4 complication, no readmissions, and no variations in pre- and postoperative functional status within 30 days from surgery were reported. No positive distal or CRMs were detected. Three pathologic complete responses were reported (20%)., Conclusions: TNT followed by TME is feasible and safe in older patients, with good clinical and oncologic outcomes. Patient evaluation is crucial for maximizing cancer care in fit older patients., Competing Interests: IM is faculty and invited speaker at Olympus SE Rectal cancer and minimally invasive surgery courses.

Background: In the TOPAZ-1, patients with biliary tract cancers (BTC) and recurrence within 6 months after surgery were excluded, even if this event is frequently observed in clinical practice. Our study aimed to assess if the efficacy of cisplatin-gemcitabine-durvalumab (CGD) in this population is comparable to that reported in the phase 3 trial., Methods: The study cohort included patients with BTC who underwent surgery on the primary tumor, experienced disease recurrence occurring ≤6 months or >6 months after surgery or after the end of adjuvant therapy and started CGD. The primary objectives were overall survival (OS) and progression free survival (PFS)., Results: A total of 178 patients were enrolled. No significant differences were observed between early and late relapse groups in OS (23.4 months vs not reached; HR 1.26; 95% CI, 0.67-2.37; P = .45) and PFS [7.0 months vs 9.8 months; HR 1.3(95% CI, 0.9-2.1) P = .13]. Overall response rate and disease control rate (P = .33 and P = .62) were comparable between the 2 groups, as the overall safety profile. In addition, we compared survival outcomes between the selected population and a historical cohort of patients with BTC treated with cisplatin-gemcitabine (CG) and found that despite the absence of statistical significance, CGD showed an outcome trend compared with CG regardless of the time of recurrence after surgery or adjuvant chemotherapy [(CG ≤ 6 vs CGD ≤ 6 months: HR 0.59, 95%CI, 0.35-1.01, P = .05; HR 0.70; 95%CI, 0.46-1.06, P = .09, OS and PFS, respectively) and (CG > 6 vs. CGD > 6 months: HR 0.50; 95%CI, 0.29-0.88, P = 0.0165; HR 0.54; 95%CI, 0.35-0.84, P = .0068, OS and PFS, respectively)]., Conclusion: Our analysis suggests that CGD retains its efficacy independently of the timing of relapse after surgery or completion of adjuvant treatment in patients with advanced BTC., (© The Author(s) 2024.

Background: Most premenopausal patients with early breast cancer (eBC) are diagnosed with hormone receptor-positive disease and therefore candidate for adjuvant endocrine therapy (ET)., Patients and Methods: The Gruppo Italiano Mammella (GIM) 23-POSTER (GIM23) is a multicenter, prospective, observational study conducted in 26 Italian institutions, aiming to evaluate ET choices for premenopausal patients affected by hormone receptor-positive eBC in a real-world setting. Here we report also the results in terms of type of ET prescribed according to the definition of high-risk patients by monarchE and NATALEE trials., Results: Between October 2019 and June 2022, 600 premenopausal patients were included, with a median age of 46 years. Almost half (271, 45.2 %) of the patients had stage I disease, while 254 (42.3 %) and 60 (10.0 %) patients had stage II and III, respectively. Overall, 149 (25.1 %) patients received tamoxifen alone, 83 (14.0 %) tamoxifen with ovarian function suppression (OFS), while 361 (60.9 %) received aromatase inhibitor (AI) with OFS. Patients treated with AI and OFS had higher number of metastatic axillary nodes, higher grade and more often received chemotherapy (all p < 0.001). According to the inclusion criteria of the monarchE and NATALEE trials, 81 patients (15.6 %) were considered high-risk for the monarchE and received AI with OFS in 88.9 % of the cases, while 231 patients (44.4 %) were considered high-risk for the NATALEE trial and received AI with OFS in 74.5 % of cases., Conclusions: AI with OFS is the most prescribed adjuvant ET among premenopausal patients, especially in the presence of high-risk features., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Eva Blondeaux: speaker fee from Eli Lilly and research support from Gilead Science (to the institution).

Background: Neuroendocrine Carcinomas (NECs) prognosis is poor.No standard second-line therapy is currently recognized after failure of platinum-based first-line treatment. FOLFIRI and CAPTEM regimens have shown promising activity in preliminary studies. We aimed to evaluate these regimens in metastatic NEC patients., Methods: This is an open-label, multicenter, randomized non-comparative phase II trial to evaluate the activity and safety of FOLFIRI or CAPTEM in metastatic NEC patients. Primary endpoints were the 12 weeks-Disease Control Rate (12w-DCR) by investigator assessment per RECIST v1.1 and safety per CTCAE v5.0. Additional endpoints included overall response rate (ORR), progression-free survival (PFS) and overall survival (OS). Patients' serum samples were subject to NGS miRNome profiling in comparison with healthy donors to reveal differentially expressed miRNAs as candidate circulating biomarkers., Results: The study was halted for futility at interim analysis, as the minimum 12w-DCR threshold of 10 out of 25 patients required for the first step was not reached. From 06/03/2017 to 18/01/2021, 53 out of 112 patients were enrolled. Median follow-up was 22.6 months (range: 1.4-60.4). The 12w-DCR was 39.1 % in the FOLFIRI arm and 28.0 % in the CAPTEM arm. In the FOLFIRI subgroup the 12-months OS rate was 28.4 % (95 % CI: 12.7-46.5) while in the CAPTEM subgroup it was 32.4 % (95 % CI: 14.9-51.3). The most common G3-G4 side effects were neutropenia (n = 5, 18.5 %) and anemia (n = 2, 7.4 %) for FOLFIRI and G3-G4 thrombocytopenia (n = 2, 8.0 %), G4 nausea/vomiting (n = 1, 4.0 %) for CAPTEM. Three microRNAs emerged as NEC independent predictors. High expression values were found to be significantly associated with decreased PFS and OS., Conclusion: The safety profile of FOLFIRI and CAPTEM was manageable. FOLFIRI and CAPTEM chemotherapy showed comparable activity in the second-line setting after progression on etoposide/platinum., Gov Identifier: NCT03387592., 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.

Background: The TOPAZ-1 phase III trial showed a survival benefit with durvalumab plus gemcitabine and cisplatin in patients with advanced biliary tract cancer (BTC). To understand this combination's real-world efficacy and tolerability, we conducted a global multicenter retrospective analysis of its first-line treatment outcomes., Methods: We included patients with unresectable, locally advanced, or metastatic BTC treated with durvalumab, gemcitabine, and cisplatin at 39 sites in 11 countries (Europe, the United States, and Asia). The primary endpoint was overall survival (OS)., Results: 666 patients were enrolled. Median OS was 15.1 months and median PFS was 8.2 months. The investigator-assessed overall response rate was 32.7 %, with stable disease in 45.2 % of patients. High baseline CEA levels, ECOG PS > 0, metastatic disease, and NLR > 3 were associated with poor survival. Any grade adverse events (AEs) occurred in 92.9 % of patients (grade >2: 46.6 %). Immune-related AEs (irAEs) occurred in 20.0 % (grade >2: 2.5 %). Three deaths (0.5 %) were deemed treatment-related, none linked to immunotherapy. Common irAEs were rash (8.2 % all grades; 0.3 % grade >2), itching (10.3 % all grades; 0.2 % grade >2), and hypothyroidism (5.1 % all grades; 0.3 % grade >2). Durvalumab discontinuation rate due to AEs was 1.5 %. ESMO-recommended genes were analyzed and no outcome differences were found. A comparative analysis with a historical cohort of patients treated with chemotherapy alone confirmed the positive survival impact of durvalumab in combination with cisplatin/gemcitabine., Conclusion: This first global real-world analysis largely confirmed the TOPAZ-1 findings, supporting gemcitabine, cisplatin, and durvalumab as a first-line standard of care for patients with advanced BTC., Competing Interests: Declaration of Competing Interest LR reports consulting fees from AbbVie, AstraZeneca, Basilea, Bayer, Elevar Therapeutics, Exelixis, Genenta, Hengrui, Incyte, Ipsen, IQVIA, Jazz Pharmaceuticals, MSD, Nerviano Medical Sciences, Roche, Servier, Taiho Oncology, Zymeworks; lecture fees from AstraZeneca, Bayer, BMS, Incyte, Ipsen, Roche, Servier; travel expenses from AstraZeneca; research grants (to Institution) from Agios, AstraZeneca, BeiGene, Eisai, Exelixis, Fibrogen, Incyte, Ipsen, Lilly, MSD, Nerviano Medical Sciences, Roche, Servier, Zymeworks.

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported. We report 4-year results of the phase II randomized AtezoTRIBE study. Eligible patients with metastatic colorectal cancer (mCRC) received first-line fluorouracil, leucovorin, oxaliplatin, and irinotecan (FOLFOXIRI)/bevacizumab (control group, n = 73) or FOLFOXIRI/bevacizumab plus atezolizumab (experimental group, n = 145). We present overall survival (OS) and updated outcomes according to tumor immune-related biomarkers, both in the intention-to-treat (ITT) population and the cohort of patients with proficient mismatch repair (pMMR) tumors. Median follow-up was 45.2 months (IQR, 42.6-49.2). In the ITT population, median OS was 33.0 and 27.2 months for experimental and control groups, respectively (hazard ratio [HR], 0.78 [80% CI, 0.61 to 0.98]; P = .084). An interaction effect between Immunoscore Immune-Checkpoint (IC) and treatment arm was observed ( P int , .089), with higher benefit from atezolizumab in the Immunoscore IC-high group. In the pMMR cohort (N = 202), median OS was 30.8 and 29.2 months for experimental and control groups, respectively (HR, 0.80 [80% CI, 0.63 to 1.02]; P = .117). Interactions between treatment group and tumor mutational burden (TMB) and Immunoscore IC were reported ( P int , .043 and .092, respectively), with patients bearing TMB-high and Immunoscore IC-high tumors deriving higher benefit from the addition of atezolizumab. First-line FOLFOXIRI/bevacizumab plus atezolizumab improves OS in patients with mCRC. In the pMMR group, patients with Immunoscore IC-high and/or TMB-high tumors are identified as a subgroup of interest to further develop this treatment.

Background: Peritoneal carcinomatosis significantly worsens the prognosis of patients with gastric cancer. Cytoreduction + hyperthermic intraperitoneal chemotherapy (HIPEC) has shown promising results in the prevention and treatment of peritoneal carcinomatosis in advanced gastric cancer (AGC); however, its application remains controversial owing to the variability of the approaches used to perform it and the lack of high-quality evidence. This systematic review and meta-analysis aimed to investigate the role of surgery and HIPEC in the prevention and treatment of peritoneal carcinomatosis of gastric origin., Methods: We conducted a systematic review and meta-analysis of randomized controlled trials comparing surgery + HIPEC vs surgery + chemotherapy for the prophylaxis of peritoneal carcinomatosis and cytoreduction + HIPEC vs chemotherapy or other palliative options for the treatment of peritoneal carcinomatosis., Results: Sixteen studies enrolling 1641 patients were included. Surgery + HIPEC significantly improved overall survival in both prophylactic (hazard ratio [HR], 0.56) and therapeutic (HR, 0.57) settings. When surgery + HIPEC was performed with prophylactic intent, the pooled 3-year mortality rate was 32%, whereas for the control group it was 55%. The overall and peritoneal recurrence rates were also reduced (risk ratio [RR], 0.59 and 0.40, respectively). No significant difference was found in morbidity between groups (RR, 0.92)., Conclusion: Based on the current knowledge, HIPEC in AGC seems to be a safe and effective tool for prophylaxis and a promising resource for the treatment of peritoneal carcinomatosis. Regarding the treatment of peritoneal carcinomatosis, the scarcity of large-cohort studies and the heterogeneity of the techniques adopted prevented us from achieving a definitive recommendation., (Copyright © 2024 Society for Surgery of the Alimentary Tract.

Background: Immunotherapy combined with chemotherapy significantly improves progression-free survival (PFS) compared to first-line chemotherapy alone in advanced endometrial cancer (EC), with a much larger effect size in microsatellite instability-high (MSI-H) cases. New biomarkers might help to select patients who may have benefit among those with a microsatellite-stable (MSS) tumor., Patients and Methods: In a pre-planned translational analysis of the MITO END-3 trial, we assessed the significance of genomic abnormalities in patients randomized to standard carboplatin/paclitaxel without or with avelumab., Results: Out of 125 randomized patients, 109 had samples eligible for next-generation sequencing analysis, and 102 had MSI tested. According to The Cancer Genome Atlas (TCGA), there were 29 cases with MSI-H, 26 with MSS TP53 wild type (wt), 47 with MSS TP53 mutated (mut), and 1 case with POLE mutation. Four mutated genes were present in >30% of cases: TP53, PIK3CA, ARID1A, and PTEN. Eleven patients (10%) had a BRCA1/2 mutation (five in MSI-H and six in MSS). High tumor mutational burden (≥10 muts/Mb) was observed in all MSI-H patients, in 4 out of 47 MSS/TP53 mut, and no case in the MSS/TP53 wt category. The effect of avelumab on PFS significantly varied according to TCGA categories, being favorable in MSI-H and worst in MSS/TP53 mut (P interaction = 0.003); a similar non-significant trend was seen in survival analysis. ARID1A and PTEN also showed a statistically significant interaction with treatment effect, which was better in the presence of the mutation (ARID1A P interaction = 0.01; PTEN P interaction = 0.002)., Conclusion: The MITO END-3 trial results suggest that TP53 mutation is associated with a poor effect of avelumab, while mutations of PTEN and ARID1A are related to a positive effect of the drug in patients with advanced EC., (Copyright © 2024 European Society for Medical Oncology.

Purpose: Literature evidence suggests that trabectedin monotherapy is effective in patients with recurrent ovarian cancer (OC) presenting BRCA mutation and/or BRCAness phenotype., Methods: A prospective, open-label, randomized phase III MITO-23 trial evaluated the activity and safety of trabectedin 1.3 mg/m 2 given once every 3 weeks (arm A) in BRCA 1/2 mutation carriers or patients with BRCAness phenotype (ie, patients who responded to ≥two previous platinum-based treatments) with recurrent OC, primary peritoneal carcinoma, or fallopian tube cancer in comparison with physician's choice chemotherapy in the control arm (arm B; pegylated liposomal doxorubicin, topotecan, gemcitabine, once-weekly paclitaxel, or carboplatin). The primary end point was overall survival (OS) evaluated in the intention-to-treat population., Results: Overall, 244 patients from 21 MITO centers were randomly assigned (arm A = 122/arm B = 122). More than 70% of patients received ≥three previous chemotherapy lines and 35.7% had received a poly (ADP-ribose) polymerase inhibitor (PARPi) before enrollment. Median OS was not significantly different between the arms: arm A: 15.8 versus arm B: 17.9 months ( P = .304). Median progression-free survival was 4.9 months in arm A versus 4.4 months in arm B ( P = .897). Among 208 patients evaluable for efficacy, the objective response rate was 17.1% in arm A and 21.4% in arm B, with comparable median duration of response (5.62 v 5.66 months, respectively). No superior effect was observed for trabectedin in the prespecified subgroup analyses according to BRCA mutational status, chemotherapy type, and pretreatment with a PARPi and/or platinum-free interval. Trabectedin showed a higher frequency of grade ≥3 adverse events (AEs), serious AEs, and serious adverse drug reactions compared with control chemotherapy., Conclusion: Trabectedin did not improve median OS and showed a worse safety profile in comparison with physician's choice control chemotherapy.

Purpose: The intensity of anti-EGFR-based first-line therapy for RAS/BRAF wild-type (wt) metastatic colorectal cancer (mCRC), once disease control is achieved, is controversial. A de-escalation strategy with anti-EGFR monotherapy represents a potential option to maintain efficacy while reducing cytotoxicity., Methods: In this multicenter, open-label, phase III trial, patients with untreated RAS/BRAF wt mCRC were randomly assigned to receive either fluorouracil, leucovorin, and irinotecan/cetuximab (FOLFIRI/Cet) until disease progression (arm A) or FOLFIRI/Cet for eight cycles followed by Cet alone (arm B). The coprimary end points were a noninferior progression-free survival (PFS) in the modified per-protocol (mPP) population (>eight cycles) and a lower incidence of grade (G) 3-4 adverse events (AEs) for arm B compared with arm A., Results: Overall, 606 patients were randomly assigned, with 300 assigned to arm A and 306 to arm B. The median follow-up was 22.3 months. In the mPP population, 291 events occurred with a PFS of 10 versus 12.2 months for arms B and A, respectively ( P of noninferiority = .43). In the intention-to-treatment (ITT, ≥one cycle) population, 503 events occurred with a PFS of 9 versus 10.7 months ( P = .39). The overall survival was 35.7 versus 30.7 months ( P = .119) and 31.0 versus 25.2 months ( P = .32) in the mPP and ITT population, respectively. Arm B had lower G3-4 AEs during the maintenance period than arm A (20.2% v 35.1%)., Conclusion: The ERMES study did not demonstrate noninferiority of maintenance with Cet alone. Despite a more favorable safety profile, maintenance with single-agent Cet after induction with FOLFIRI/Cet cannot be recommended for all patients but could represent an option in selected cases.

Background: Biliary tract cancers (BTCs) are rare and lethal cancers, with a 5-year survival inferior to 20%(1-3). The only potential curative treatment is surgical resection. However, despite complex surgical procedures that have a remarkable risk of postoperative morbidity and mortality, the 5-year survival rate after radical surgery (R0) is 20-40% and recurrence rates are up to ~ 75%(4-6). Up to ~ 40% of patients relapse within 12 months after resection, and half of these patient will recur systemically(4-6). There is no standard of care for neoadjuvant chemotherapy (NAC) in resectable BTC, but retrospective reports suggest its potential benefit (7, 8)., Methods: PURITY is a no-profit, multicentre, randomized phase II/III trial aimed at evaluating the efficacy of the combination of gemcitabine, cisplatin and nabpaclitaxel (GAP) as neoadjuvant treatment in patients with resectable BTC at high risk for recurrence. Primary objective of this study is to evaluate the efficacy of neoadjuvant GAP followed by surgery as compared to upfront surgery, in terms of 12-month progression-free survival for the phase II part and of progression free survival (PFS) for the phase III study. Key Secondary objectives are event free survival (EFS), relapse-free survival, (RFS), overall survival (OS), R0/R1/R2 resection rate, quality of life (QoL), overall response rate (ORR), resectability. Safety analyses will include toxicity rate and perioperative morbidity and mortality rate. Exploratory studies including Next-Generation Sequencing (NGS) in archival tumor tissues and longitudinal ctDNA analysis are planned to identify potential biomarkers of primary resistance and prognosis., Discussion: Considering the poor prognosis of resected BTC experiencing early tumor recurrence and the negative prognostic impact of R1/R2 resections, PURITY study is based on the rationale that NAC may improve R0 resection rates and ultimately patients' outcomes. Furthermore, NAC should allow early eradication of microscopic distant metastases, undetectable by imaging but already present at the time of diagnosis and avoid mortality and morbidity associated with resection for patients with rapid progression or worsening general condition during neoadjuvant therapy. The randomized PURITY study will evaluate whether patients affected by BTC at high risk from recurrence benefit from a neoadjuvant therapy with GAP regimen as compared to immediate surgery., Trial Registration: PURITY is registered at ClinicalTrials.gov (NCT06037980) and EuCT(2023-503295-25-00)., (© 2024.

Purpose: In estrogen receptor-positive (ER+) breast cancer, single-nucleotide polymorphisms (SNP) in the aromatase gene might affect aromatase inhibitors (AI) metabolism and efficacy. Here, we assessed the impact of SNP on prognosis and toxicity of patients receiving adjuvant letrozole., Experimental Design: We enrolled 886 postmenopausal patients in the study. They were treated with letrozole for 2 to 5 years after taking tamoxifen for 2 to 6 years, continuing until they completed 5 to 10 years of therapy. Germline DNA was genotyped for SNP rs4646, rs10046, rs749292, and rs727479. Log-rank test and Cox model were used for disease-free survival (DFS) and overall survival (OS). Cumulative incidence (CI) of breast cancer metastasis was assessed through competing risk analysis, with contralateral breast cancer, second malignancies and non-breast cancer death as competing events. CI of skeletal and cardiovascular events were assessed using DFS events as competing events. Subdistribution HR (sHR) with 95% confidence intervals were calculated through Fine-Gray method., Results: No SNP was associated with DFS. Variants rs10046 [sHR 2.03, (1.04-2.94)], rs749292 [sHR 2.11, (1.12-3.94)], and rs727479 [sHR 2.62, (1.17-5.83)] were associated with breast cancer metastasis. Three groups were identified on the basis of the number of these variants (0, 1, >1). Variant-based groups were associated with breast cancer metastasis (10-year CI 2.5%, 7.6%, 10.7%, P = 0.035) and OS (10-year estimates 96.5%, 93.0%, 89.6%, P = 0.030). Co-occurrence of rs10046 and rs749292 was negatively associated with 10-year CI of skeletal events (3.2% vs. 10%, P = 0.033). A similar association emerged between rs727479 and cardiovascular events (0.3% vs. 2.1%, P = 0.026)., Conclusions: SNP of aromatase gene predict risk of metastasis and AI-related toxicity in ER+ early breast cancer, opening an opportunity for better treatment individualization., (©2023 The Authors; Published by the American Association for Cancer Research.)

Background: This study investigated the efficacy of chemoradiotherapy (CRT) followed by durvalumab as neoadjuvant therapy of locally advanced rectal cancer., Patients and Methods: The PANDORA trial is a prospective, phase II, open-label, single-arm, multicenter study aimed at evaluating the efficacy and safety of preoperative treatment with durvalumab (1500 mg every 4 weeks for three administrations) following long-course radiotherapy (RT) plus concomitant capecitabine (5040 cGy RT in 25-28 fractions over 5 weeks and capecitabine administered at 825 mg/m 2 twice daily). The primary endpoint was the pathological complete response (pCR) rate; secondary endpoints were the proportion of clinical complete remissions and safety. The sample size was estimated assuming a null pCR proportion of 0.15 and an alternative pCR proportion of 0.30 (α = 0.05, power = 0.80). The proposed treatment could be considered promising if ≥13 pCRs were observed in 55 patients (EudraCT: 2018-004758-39; NCT04083365)., Results: Between November 2019 and August 2021, 60 patients were accrued, of which 55 were assessable for the study's objectives. Two patients experienced disease progression during treatment. Nineteen out of 55 eligible patients achieved a pCR (34.5%, 95% confidence interval 22.2% to 48.6%). Regarding toxicity related to durvalumab, grade 3 adverse events (AEs) occurred in four patients (7.3%) (diarrhea, skin toxicity, transaminase increase, lipase increase, and pancolitis). Grade 4 toxicity was not observed. In 20 patients (36.4%), grade 1-2 AEs related to durvalumab were observed. The most common were endocrine toxicity (hyper/hypothyroidism), dermatologic toxicity (skin rash), and gastrointestinal toxicity (transaminase increase, nausea, diarrhea, constipation)., Conclusion: This study met its primary endpoint showing that CRT followed by durvalumab could increase pCR with a safe toxicity profile. This combination is a promising, feasible strategy worthy of further investigation., (Copyright © 2023 The Authors. Published by Elsevier Ltd.. All rights reserved.)

Background: Thymidine kinase 1 (TK1) is an enzyme downstream of the CDK4/6 pathway, with a critical role in DNA synthesis; serum TK1 activity (sTKa) is a novel liquid biopsy biomarker of tumour cell proliferation., Methods: The phase IIIb, BioItaLEE trial (NCT03439046) collected sera from postmenopausal patients with hormone receptor-positive (HR+), HER2-negative (HER2-) advanced breast cancer (ABC) treated with first-line ribociclib plus letrozole at baseline, day 15 of cycle 1 (C1D15), day 1 of cycle 2 (C2D1), and at first imaging. Associations between sTKa assessed at different time points or sTKa dynamic patterns, and progression-free survival (PFS) were evaluated using multivariate Cox models., Results: Overall, 287 patients were enroled. Median follow-up was 26.9 months. High sTKa (>median) at baseline was associated with higher risk of progression (hazard ratio [HR], 2.21; 95% confidence interval [95% CI], 1.45, 3.37; P = 0.0002); similar results were observed for patients with high sTKa levels at C1D15 and C2D1. Early sTKa dynamic patterns were strongly predictive of PFS. The pattern with high sTKa levels at C2D1 following initial decrease at C1D15 was associated with higher risk of progression versus the pattern with low sTKa levels at both time points (HR, 2.89; 95% CI, 1.57, 5.31; P = 0.0006), while the pattern with high sTKa levels at C1D15 was associated with the shortest PFS (HR, 5.65; CI: 2.84, 11.2; P < 0.0001). Baseline and dynamic sTKa changes provided independent information., Conclusions: sTKa appears to be a new promising prognostic and pharmacodynamic biomarker in patients with HR+/HER2- ABC treated with ribociclib plus letrozole as first-line therapy., (Copyright © 2023 The Authors.

Background: Prior exposure to adjuvant endocrine therapy (ET) and timing to recurrence are crucial factors for first-line treatment choices in patients with hormone receptor-positive/HER2-negative (HR+/HER2-) breast cancer (BC) and in clinical trial eligibility, classifying metastatic HR+/HER2- BC as endocrine sensitive (ES) or primary (1ER)/secondary (2ER) resistant. However, this classification is largely based on expert opinion and no proper evidence exists to date to support its possible prognostic and clinical impact., Methods: This analysis included individual patient-level data from 4 adjuvant phase III randomized trials by the Mammella InterGruppo (MIG) and Gruppo Italiano Mammella (GIM) study groups. The impact of endocrine resistance/sensitivity classification on overall survival (mOS, defined as time between date of distant relapse and death) was assessed in both univariate and multivariate Cox proportional hazards models., Findings: Between November 1992 and July 2012, 9058 patients were randomized in 4 trials, of whom 6612 had HR+/HER2- BC. Median follow-up was 9.1 years (interquartile range [IQR] 5.6-15.0). In the whole cohort, disease-free survival and OS were 90.4% and 96.6% at 5 years, and 79.1% and 89.4% at 10 years, respectively. The estimated hazard of recurrence raised constantly during the first 15 years from diagnosis, being more pronounced during the first 2 years and less pronounced after year 7. Among the 493 patients with a distant relapse as first disease-free survival event and available date on ET completion, 72 (14.6%), 207 (42.0%) and 214 (43.4%) were classified as having 1ER, 2ER and ES, respectively. Median follow-up from diagnosis of a distant relapse was 3.8 years (IQR 1.6-7.5). Patients with 1ER were significantly more likely to be younger, to have N2/N3 nodal status, grade 3 tumours and to develop visceral metastases. Site of first distant relapse was significantly different between the 3 groups (p = 0.005). In patients with 1ER, 2ER and ES breast cancer, median mOS was 27.2, 38.4 and 43.2 months, respectively (p = 0.03). As compared to patients with ES disease, a higher risk of death was observed in those with 1 ER (adjusted Hazard Ratio [aHR] 1.54; 95% CI 1.03-2.30) and 2ER (aHR 1.17; 95% CI 0.87-1.56) (p = 0.11)., Interpretation: This large analysis with long-term follow-up provides evidence on the prognostic and clinical impact of the currently adopted endocrine resistance/sensitivity classification in patients with HR+/HER2- advanced BC. This classification may be considered a valid tool to guide clinical decision-making and to design future ET trials in the metastatic setting., Funding: AIRC., Competing Interests: ML reports advisory role for Roche, Lilly, Novartis, Astrazeneca, Pfizer, Seagen, Gilead, MSD and Exact Sciences; speaker honoraria from Roche, Lilly, Novartis, Pfizer, Sandoz, Libbs, and Takeda; travel Grants from Gilead outside the submitted work.

Background: Tumor immune cells influence the efficacy of immune-checkpoint inhibitors (ICIs) and many efforts aim at identifying features of tumor immune microenvironment able to predict benefit from ICIs in proficient mismatch repair (pMMR)/microsatellite stable (MSS) metastatic colorectal cancer (mCRC)., Methods: We characterized tumor immune cell infiltrate, by assessing tumor-infiltrating lymphocytes (TILs), Immunoscore, Immunoscore-IC, and programmed death ligand-1 (PD-L1) expression in tumor samples of patients with mCRC enrolled in the AtezoTRIBE study, a phase II randomized trial comparing FOLFOXIRI/bevacizumab/atezolizumab to FOLFOXIRI/bevacizumab, with the aim of evaluating the prognostic and predictive value of these features., Results: Out of 218 patients enrolled, 181 (83%), 77 (35%), 157 (72%) and 162 (74%) specimens were successfully tested for TILs, Immunoscore, Immunoscore-IC and PD-L1 expression, respectively, and 69 (38%), 45 (58%), 50 (32%) and 21 (13%) tumors were classified as TILs-high, Immunoscore-high, Immunoscore-IC-high and PD-L1-high, respectively. A poor agreement was observed between TILs and Immunoscore or Immunoscore-IC (K of Cohen <0.20). In the pMMR population, longer progression-free survival (PFS) was reported for Immunoscore-high and Immunoscore-IC-high groups compared with Immunoscore-low (16.4 vs 12.2 months; HR: 0.55, 95% CI: 0.30 to 0.99; p=0.049) and Immunoscore-IC-low (14.8 vs 11.5 months; HR: 0.55, 95% CI: 0.35 to 0.85; p=0.007), respectively, with a significant interaction effect between treatment arms and Immunoscore-IC (p for interaction: 0.006) and a trend for Immunoscore (p for interaction: 0.13). No PFS difference was shown according to TILs and PD-L1 expression. Consistent results were reported in the overall population., Conclusions: The digital evaluation of tumor immune cell infiltrate by means of Immunoscore-IC or Immunoscore identifies the subset of patients with pMMR mCRC achieving more benefit from the addition of the anti-PD-L1 to the upfront treatment. Immunoscore-IC stands as the most promising predictor of benefit from ICIs., Competing Interests: Competing interests: AC, AK, JF: are Veracyte employees.

Aim: Colorectal cancer (CRC) surgery can be associated with suboptimal outcomes in older patients. The aim was to identify the correlation between frailty and surgical variables with the achievement of Textbook Outcome (TO), a composite measure of the ideal postoperative course, by older patients with CRC., Method: All consecutive patients ≥70years who underwent elective CRC-surgery between January 2017 and November 2021 were analyzed from a prospective database. To obtain a TO, all the following must be achieved: 90-day survival, Clavien-Dindo (CD) < 3, no reintervention, no readmission, no discharge to rehabilitation facility, no changes in the living situation and length of stay (LOS) ≤5days/≤14days for colon and rectal surgery respectively. Frailty and surgical variables were related to the achievement of TO., Results: Four-hundred-twenty-one consecutive patients had surgery (97.7% minimally invasive), 24.9% for rectal cancer, median age 80 years (range 70-92), median LOS of 4 days (range 1-96). Overall, 288/421 patients (68.4%) achieved a TO. CD 3-4 complications rate was 6.4%, 90-day mortality rate was 2.9%. At univariate analysis, frailty and surgical variables (ileostomy creation, p = 0.045) were related to. However, multivariate analysis showed that only frailty measures such as flemish Triage Risk Screening Tool≥2 (OR 1.97, 95%CI: 1.23-3.16; p = 0.005); Charlson Index>6 (OR 1.61, 95%CI: 1.03-2.51; p = 0.036) or Timed-Up-and-Go>20 s (OR 2.06, 95%CI: 1.01-4.19; p = 0.048) independently predicted an increased risk of not achieving a TO., Conclusion: The association between frailty and comprehensive surgical outcomes offers objective data for guiding family counseling, managing expectations and discussing the possible loss of independence with patients and caregivers., 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 Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

Background: The Meet-URO score allowed a more accurate prognostication than the International Metastatic RCC Database Consortium (IMDC) for patients with pre-treated metastatic renal cell carcinoma (mRCC) by adding the pre-treatment neutrophil-to-lymphocyte ratio and presence of bone metastases., Materials and Methods: A post hoc analysis was carried out to validate the Meet-URO score on the overall survival (OS) of patients with IMDC intermediate-poor-risk mRCC treated with first-line nivolumab plus ipilimumab within the prospective Italian Expanded Access Programme (EAP). We additionally considered progression-free survival (PFS) and disease response rates. Harrell's c-index was calculated to compare the accuracy of survival prediction., Results: Overall the EAP included 306 patients, with a median follow-up of 12.2 months, median OS was not reached, 1-year OS was 66.8% and median PFS was 7.9 months. By univariable analysis, both the IMDC score and the two additional variables of the Meet-URO score were associated with either OS or PFS (P < 0.001 for all comparisons). The four Meet-URO risk groups (G) had 1-year OS of 92%, 72%, 50% and 21% for G2 (29.1% of patients), G3 (28.8%), G4 (33.0%) and G5 (9.1%), respectively. OS was significantly shorter in each consecutive G (P = 0.001 for G3, P < 0.001 for both G4 and G5 compared to G2). Similarly, Meet-URO Gs 2-5 showed decreasing median PFS and response rates. The Meet-URO score showed the highest c-index for both OS (0.73) and PFS (0.67). Limitations include the post hoc nature of this analysis and the lack of a comparative arm to assess predictive value., Conclusion: The Meet-URO score appeared to show better prognostic classification than the IMDC alone in patients with mRCC at IMDC intermediate-poor risk treated with first-line nivolumab and ipilimumab., Competing Interests: Disclosure SER received honoraria as a speaker at scientific events and travel accommodation from Amgen, GSK, BMS, MSD.

Objective: This open-label phase II clinical trial evaluated the antitumor activity and safety of trabectedin in patients with advanced ovarian (OC) or uterine carcinosarcomas (UC)., Methods: Eligible patients were adults (≥18 years) with histologically proven recurrent OC/UC not amenable to surgery or radiotherapy who received up to two prior chemotherapy lines. Trabectedin 1.3 mg/m 2 was administered as a 3-h infusion every three weeks. The primary endpoint was objective response rate (ORR) as per RECIST v.1.1. If at least 8 of 43 patients (18.6%) achieve an objective response, trabectedin would be declared worthy for further investigations., Results: Forty-five patients with either OC (n = 32) or UC (n = 13) from seven MITO centers across Italy were enrolled. The ORR was 11.9% (90% CI: 6-23) and included two patients with a complete response and three with a partial response. Eight patients (19.0%) had disease stabilization for a disease control rate of 31.0% (90% CI: 20-44). Median progression-free survival was 2.01 months (95% CI: 1.78-2.30) and median overall survival was 4.64 months (95% CI: 3.19-8.29). Neutrophil count decreases (n = 8, 18.2%) and transaminase increases (n = 6, 13.6%) were the most common grade 3-5 adverse events related with trabectedin. Two patients died due to trabectedin-related grade 5 hematological toxicity., Conclusion: Although trabectedin did not meet the prespecified activity criteria, it confers modest but clinically meaningful benefit to patients with advanced OC/UC as being as effective as any other available treatment for this indication. The toxicity profile appears in line with that previously reported for the drug., Competing Interests: Declaration of Competing Interest DL reports personal fees, travel support and institutional grants and founding from PharmaMar.

Background: Locally advanced or metastatic squamous carcinoma of the anal canal (SCAC) has poor prognosis following platinum-based chemotherapy. Retifanlimab (INCMGA00012), a humanized monoclonal antibody targeting programmed death protein-1 (PD-1), demonstrated clinical activity across a range of solid tumors in clinical trials. We present results from POD1UM-202 (NCT03597295), an open-label, single-arm, multicenter, phase II study evaluating retifanlimab in patients with previously treated advanced or metastatic SCAC., Patients and Methods: Patients ≥18 years of age had measurable disease and had progressed following, or were ineligible for, platinum-based therapy. Retifanlimab 500 mg was administered intravenously every 4 weeks. The primary endpoint was overall response rate (ORR) by independent central review. Secondary endpoints were duration of response (DOR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and safety., Results: Overall, 94 patients were enrolled. At a median follow-up of 7.1 months (range, 0.9-19.4 months), ORR was 13.8% [95% confidence interval (CI) 7.6% to 22.5%], with one complete response (1.1%) and 12 partial responses (12.8%). Responses were observed regardless of human immunodeficiency virus or human papillomavirus status, programmed death ligand 1 (PD-L1) expression, or liver metastases. Stable disease was observed in 33 patients (35.1%) for a DCR of 48.9% (95% CI 38.5% to 59.5%). Median DOR was 9.5 months (range, 5.6 months-not estimable). Median (95% CI) PFS and OS were 2.3 (1.9-3.6) and 10.1 (7.9-not estimable) months, respectively. Retifanlimab safety in this population was consistent with previous experience for the PD-(L)1 inhibitor class., Conclusions: Retifanlimab demonstrated clinically meaningful and durable antitumor activity, and an acceptable safety profile in patients with previously treated locally advanced or metastatic SCAC who have progressed on or are intolerant to platinum-based chemotherapy., Competing Interests: Disclosure SR reports being an advisor or receiving honoraria from Amgen, Celgene, and Shire; travel grants from Bayer, Celgene, and Incyte Corporation.

Background: Immune checkpoint inhibitors have not shown clinical benefit to patients with metastatic colorectal cancer who had proficient mismatch repair (pMMR) or microsatellite stable (MSS) tumours in previous studies. Both an active combination chemotherapy (FOLFOXIRI; fluorouracil, leucovorin, oxaliplatin, and irinotecan) and bevacizumab seem able to increase the immunogenicity of pMMR or MSS tumours. We aimed to provide preliminary evidence of benefit from the addition of the anti-PD-L1 agent atezolizumab to first-line FOLFOXIRI plus bevacizumab in patients with metastatic colorectal cancer., Methods: AtezoTRIBE was a multicentre, open-label, randomised, controlled, phase 2 study of patients (aged 18-70 years with an Eastern Cooperative Oncology Group [ECOG] performance status of 0-2 and aged 71-75 years with an ECOG performance status of 0) with histologically confirmed, unresectable, previously untreated metastatic colorectal cancer and adequate organ function, who were recruited from 22 oncology centres in Italy. Patients were stratified according to centre, ECOG performance status, primary tumour site, and previous adjuvant therapy. A randomisation system incorporating a minimisation algorithm randomly assigned (1:2) patients via a masked web-based allocation procedure to two groups: the control group received first-line FOLFOXIRI (intravenous 165 mg/m 2 irinotecan, 85 mg/m 2 oxaliplatin, 200 mg/m 2 leucovorin, and 3200 mg/m 2 fluorouracil as a 48 h infusion) plus bevacizumab (5 mg/kg intravenously), and the atezolizumab group received the same regimen plus atezolizumab (840 mg intravenously). Combination treatments were administered up to eight 14-day cycles followed by maintenance with fluorouracil and leucovorin plus bevacizumab with or without atezolizumab, according to randomisation group, until disease progression, unacceptable adverse events, or consent withdrawal. The primary endpoint was progression-free survival, analysed by the intention-to-treat principle. Safety was assessed in patients who received at least one dose of the study treatment. The study recruitment is completed. The trial is registered with Clinicaltrials.gov, NCT03721653., Findings: Between Nov 30, 2018, and Feb 26, 2020, 218 patients were randomly assigned and received treatment (73 in the control group and 145 in the atezolizumab group). At the data cutoff (Aug 1, 2021), median follow-up was 19·9 months (IQR 17·3-23·9). Median progression-free survival was 13·1 months (80% CI 12·5-13·8) in the atezolizumab group and 11·5 months (10·0-12·6) in the control group (hazard ratio [HR] 0·69 [80% CI 0·56-0·85]; p=0·012; adjusted HR 0·70 [80% CI 0·57-0·87]; log-rank test p=0·018). The most frequent all-cause grade 3-4 adverse events were neutropenia (59 [42%] of 142 patients in the atezolizumab group vs 26 [36%] of 72 patients in the control group), diarrhoea (21 [15%] vs nine [13%]), and febrile neutropenia (14 [10%] vs seven [10%]). Serious adverse events were reported in 39 (27%) patients in the atezolizumab group and in 19 (26%) patients in the control group. Two (1%) treatment-related deaths (due to acute myocardial infarction and bronchopulmonary haemorrhage) were reported in the atezolizumab group; none were reported in the control group., Interpretation: The addition of atezolizumab to first-line FOLFOXIRI plus bevacizumab is safe and improved progression-free survival in patients with previously untreated metastatic colorectal cancer., Funding: GONO Foundation, ARCO Foundation, F Hoffmann-La Roche, and Roche., Competing Interests: Declaration of interests DR received honoraria from Merck Sharp & Dohme (MSD).

Background: Encorafenib plus cetuximab with or without binimetinib showed increased objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) compared with chemotherapy plus anti-EGFR in previously treated patients with BRAF V600E-mutated (mut) metastatic colorectal cancer (mCRC). Although no formal comparison was planned, addition of binimetinib to encorafenib plus cetuximab did not provide significant efficacy advantage., Patients and Methods: This real-life study was aimed at evaluating safety, activity, and efficacy of encorafenib plus cetuximab with or without binimetinib in patients with BRAF V600E-mut mCRC treated at 21 Italian centers within a nominal use program launched in May 2019., Results: Out of 133 patients included, 97 (73%) received encorafenib plus cetuximab (targeted doublet) and 36 (27%) the same therapy plus binimetinib (targeted triplet). Most patients had Eastern Cooperative Group Performance Status (ECOG-PS) of 0 or 1 (86%), right-sided primary tumor (69%), and synchronous disease (66%). Twenty (15%) tumors were DNA mismatch repair deficiency (dMMR)/microsatellite instability (MSI)-high. As many as 44 (34%) patients had received two or more prior lines of therapy, 122 (92%) were previously exposed to oxaliplatin, and 109 (82%) to anti-vascular endothelial growth factor (anti-VEGF). Most frequent adverse events were asthenia (62%) and anti-EGFR-related skin rash (52%). Any grade nausea (P = 0.03), vomiting (P = 0.04), and diarrhea (P = 0.07) were more frequent with the triplet therapy, while melanocytic nevi were less common (P = 0.06). Overall, ORR and disease control rate (DCR) were 23% and 69%, respectively, with numerically higher rates in the triplet group (ORR 31% versus 17%, P = 0.12; DCR 78% versus 65%, P = 0.23). Median PFS and OS were 4.5 and 7.2 months, respectively. Worse ECOG-PS, peritoneal metastases, and more than one prior treatment were independent poor prognostic factors for PFS and OS. Clonality of BRAF mutation measured as adjusted mutant allele fraction in tumor tissue was not associated with clinical outcome., Conclusions: Our real-life data are consistent with those from the BEACON trial in terms of safety, activity, and efficacy. Patients in good general condition and not heavily pretreated are those more likely to derive benefit from the targeted treatment., Competing Interests: Disclosure MS reports being on the advisory board and speakers’ bureau for MERCK, MSD, Sanofi, Amgen, BMS, EISAI, and Servier.

Analysis of plasma-derived cell-free DNA (cfDNA) might allow for the early identification of resistance in metastatic colorectal carcinoma (mCRC) patients receiving anti-EGFR monoclonal antibodies. We tested plasma samples from the Erbitux Metastatic Colorectal Cancer Strategy (ERMES) phase III trial of FOLFIRI+Cetuximab in first-line treatment of RAS/BRAF wild-type mCRC. Samples were collected at baseline ( n = 37), at 8 weeks of treatment ( n = 32), progressive disease (PD; n = 36) and 3 months after PD ( n = 21). cfDNA testing was performed using the Idylla™ ctKRAS and ctNRAS-BRAF tests and the Oncomine Pan-Cancer Cell-Free Assay. Analysis of basal samples revealed RAS/BRAF mutations in 6/37 cases. A transient RAS positivity not associated with PD was observed at 8 weeks in five cases that showed no mutations at baseline and PD. The frequency of mutant cases increased at PD (33.3%) and decreased again at 3 months after PD (9.5%). The median progression-free survival (mPFS) of patients RAS/BRAF mutant at PD was 7.13 months versus 7.71 months in wild-type patients ( p = 0.3892). These data confirm that the occurrence of RAS/BRAF mutations in mCRC patients receiving anti-EGFR agents is relatively frequent. However, the cfDNA dynamics of RAS mutations in patients treated with anti-EGFR agents plus polychemotherapy are complex and might not be directly associated with resistance to treatment.

Background: The benefit of extending aromatase inhibitor therapy beyond 5 years in the context of previous aromatase inhibitors remains controversial. We aimed to compare extended therapy with letrozole for 5 years versus the standard duration of 2-3 years of letrozole in postmenopausal patients with breast cancer who have already received 2-3 years of tamoxifen., Methods: This multicentre, open-label, randomised, phase 3 trial was done at 69 hospitals in Italy. Women were eligible if they were postmenopausal at the time of study entry, had stage I-III histologically proven and operable invasive hormone receptor-positive breast cancer, had received adjuvant tamoxifen therapy for at least 2 years but no longer than 3 years and 3 months, had no signs of disease recurrence, and had an Eastern Cooperative Oncology Group performance status of 2 or lower. Patients were randomly assigned (1:1) to receive 2-3 years (control group) or 5 years (extended group) of letrozole (2·5 mg orally once a day). Randomisation, with stratification by centre, with permuted blocks of size 12, was done with a centralised, interactive, internet-based system that randomly generated the treatment allocation. Participants and investigators were not masked to treatment assignment. The primary endpoint was invasive disease-free survival in the intention-to-treat population. Safety analysis was done for patients who received at least 1 month of study treatment. This trial was registered with EudraCT, 2005-001212-44, and ClinicalTrials.gov, NCT01064635., Findings: Between Aug 1, 2005, and Oct 24, 2010, 2056 patients were enrolled and randomly assigned to receive letrozole for 2-3 years (n=1030; control group) or for 5 years (n=1026; extended group). After a median follow-up of 11·7 years (IQR 9·5-13·1), disease-free survival events occurred in 262 (25·4%) of 1030 patients in the control group and 212 (20·7%) of 1026 in the extended group. 12-year disease-free survival was 62% (95% CI 57-66) in the control group and 67% (62-71) in the extended group (hazard ratio 0·78, 95% CI 0·65-0·93; p=0·0064). The most common grade 3 and 4 adverse events were arthralgia (22 [2·2%] of 983 patients in the control group vs 29 [3·0%] of 977 in the extended group) and myalgia (seven [0·7%] vs nine [0·9%]). There were three (0·3%) serious treatment-related adverse events in the control group and eight (0·8%) in the extended group. No deaths related to toxic effects were observed., Interpretation: In postmenopausal patients with breast cancer who received 2-3 years of tamoxifen, extended treatment with 5 years of letrozole resulted in a significant improvement in disease-free survival compared with the standard 2-3 years of letrozole. Sequential endocrine therapy with tamoxifen for 2-3 years followed by letrozole for 5 years should be considered as one of the optimal standard endocrine treatments for postmenopausal patients with hormone receptor-positive breast cancer., Funding: Novartis and the Italian Ministry of Health., Translation: For the Italian translation of the abstract see Supplementary Materials section., Competing Interests: Declaration of interests LDM receives honoraria and non-financial support from Roche, Novartis, Pfizer, MSD, Genomic Health, Takeda, Ipsen, Eisai, Eli Lilly, Celgene, Pierre Fabre, Seagen, Daiichi Sankyo, Exact Sciences, and Amgen.

Introduction: Little consideration is given to the referral and uptake of available supportive services after distress screening. However, identifying the reasons for accepting or refusing help is mandatory for implementing a screening policy. The present study explored the practical usefulness of and potential barriers to the application of distress management., Methods: 406 cancer patients were consecutively selected and asked to complete the Distress Thermometer (DT) and Problem Check List (PL). All patients with a DT score ≥6 were invited for a post-DT telephone interview with a trained psychologist., Results: The 112 patients who refused to take part were more often older, retired, at a more advanced stage of illness, and with no previous experience of psychological intervention with respect to those who accepted. Of the 78 patients with a score ≥6 who were referred to the Psycho-Oncology Service, 65.4% accepted the telephone interview. Twenty-two patients rejected the initial invitation immediately for various reasons including logistic difficulties, physical problems, and feeling embarrassed about opening up to a psychologist., Conclusions: Our study confirms that screening per sé is insufficient to deal with the problem of distress and that more emphasis should be placed on implementing referral and treatment.

Around 8-12% of patients with advanced colon rectal cancer (CRC) present with BRAF alterations, in particular V600E mutation, which is associated with right-side, poorly differentiated and mucinous type tumors. The presence of BRAF mutation (BRAF-mt) has been identified as a hallmark of poor prognosis and treatment optimization in this patient subgroup is an important goal. Currently, the standard of care is an aggressive strategy involving triplet chemotherapy and anti-VEGF agents, but new therapeutic approaches are emerging. Very promising results have been obtained with targeted therapy combinations, such as anti-BRAF agents plus anti-EGFR agents. Furthermore, around 60% of BRAF-mt patients show a strong association with high microsatellite instability (MSI-H) and immune checkpoint inhibitors could represent the new standard of care for this subgroup. The focus of this review is to summarize current strategies for BRAF-mt CRC treatment and highlight new therapeutic options., 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 © 2021 Grassi, Corbelli, Papiani, Barbera, Gazzaneo and Tamberi.)

In resectable gastric or gastroesophageal junction cancer (GC/GEJC), the powerful positive prognostic effect and the potential predictive value for a lack of benefit from the combination of adjuvant/peri-operative chemotherapy for the MSI-high status was demonstrated. Given the high sensitivity of MSI-high tumors for immunotherapy, exploratory trials showed that combination immunotherapy induces a high rate of complete pathological response (pCR), potentially achieving cancer cure without surgery. INFINITY is an ongoing phase II, multicentre, single-arm, multi-cohort trial investigating the activity and safety of tremelimumab and durvalumab as neoadjuvant (Cohort 1) or potentially definitive (Cohort 2) treatment for MSI-high/dMMR/EBV-negative, resectable GC/GEJC. About 310 patients will be pre-screened, to enroll a total of 31 patients, 18 and 13 in Cohort 1 and 2, at 25 Italian Centres. The primary endpoint of Cohort 1 is rate of pCR (ypT0N0) and negative ctDNA after neoadjuvant immunotherapy, of Cohort 2 is 2-year complete response rate, defined as absence of macroscopic or microscopic residual disease (locally/regionally/distantly) at radiological examinations, tissue and liquid biopsy, during non-operative management without salvage gastrectomy. The ongoing INFINITY proof-of-concept study may provide evidence on immunotherapy and the potential omission of surgery in localized/locally advanced GC/GEJC patients selected for dMMR/MSI-high status eligible for radical resection.

Background: Pancreatic cancer (PC) is a major cause of cancer death. In an effort to improve treatment strategies and outcomes, DNA damage repair (DDR) pathways have been introduced as a new target in PC and in other cancers, through the exploitation of synthetic lethality. Furthermore, genes involved in DDR are among the major determinants of cancer susceptibility. In addition to the well-known BRCA1 and BRCA2 genes, a plethora of other targets in the same pathways are now emerging., Methods: We analyzed samples from 60 patients, affected by PC and already tested for BRCA, using a panel with 24 other cancer susceptibility genes., Results: We detected 8 pathogenic or likely pathogenic mutations (13.3% of samples analyzed), 4 of which were found in non-BRCA genes (2 in ATM, 1 each in PALB2 and RAD50). Furthermore, 4 pathogenic or likely pathogenic mutations were found in patients without a personal or familial history of cancer., Conclusions: Our results suggest that genetic testing with a comprehensive gene panel should be perfomed in all patients with PC, in order to allow screening for PC and other gene-related cancers in all at risk family members and to assess patients' eligibility for emerging therapeutic options.

Background: No predictive markers for chemotherapy activity have been validated in gastric cancer (GC). The potential value of class III β-tubulin (TUBB3) as biomarker for prognosis and resistance to taxane-based therapy was reported., Methods: We analyzed GC samples of patients enrolled in the Intergroup Trial of Adjuvant Chemotherapy in Adenocarcinoma of the Stomach (ITACA-S), a randomized adjuvant study comparing 5-fluorouracil/leucovorin (5-FU/LV) and docetaxel-based sequential chemotherapy. TUBB3 was quantitated by selected reaction monitoring mass spectrometry and patients were stratified using a threshold of 750 attomoles per microgram (amol/µg). Cox proportional modeling and Kaplan-Meier survival analysis were used to assess the impact of TUBB3 expression on overall survival (OS) and disease-free survival., Results: Patients with TUBB3 protein levels >750 and <750 amol/µg were 21.9% and 78.1%, respectively, and were well-balanced between treatment arms. TUBB3 protein levels were not prognostic. Whereas no survival differences according to the 2 arms were observed in the subgroup with low TUBB3 expression (5-year OS 47% vs 40%; p = 0.44), patients with high TUBB3 had a clinically meaningful poorer OS when receiving docetaxel-based versus 5-FU/LV chemotherapy (5-year OS 31% vs 54%; p = 0.09), with a statistically significant interaction between TUBB3 and treatment ( p = 0.049)., Conclusions: The quantification of TUBB3 might be considered as a negative predictive biomarker of benefit from taxane-based therapy in GC. Studies are needed to evaluate its role in the neoadjuvant setting.

Background: Although elderly patients (≥70 years) represent 30% of new diagnoses of soft tissue sarcoma (STS), they are underrepresented in clinical trials and are often unfit to receive standard anthracycline-based chemotherapy. Trabectedin is registered as a second-line treatment for advanced STS and is characterized by a favorable safety profile., Methods: The aim of this single-arm, phase 2 study was to investigate trabectedin (scheduled dose, 1.3-1.5 mg/m 2 ) as a first-line treatment in elderly patients with advanced stage STS who are inoperable and are unfit to receive standard anthracycline-based chemotherapy. The coprimary endpoints were progression-free survival at 3 months (PFS3) and the rate of clinically limiting toxicities (CLTs). We also conducted an ancillary study on pharmacokinetics., Results: Twenty-four patients (12 men and 12 women) with a median age of 79 years (interquartile range [IQR], 74-83 years) were enrolled. The histological subtype was leiomyosarcoma in 46%, liposarcoma in 33%, and other histotypes in 21%. The median number of trabectedin courses was 4 (IQR, 3-6), with 7 patients (29%) receiving ≥6 cycles. Eight patients (33%) required dose reductions. The most frequent grade 3/4 adverse events were neutropenia in 9 patients (38%), fatigue in 5 patients (21%), and aminotransferase elevation in 5 patients (21%). PFS3, median PFS, and overall survival were 71% (80% CI, 57%-81%), 4 months, and 12 months, respectively. Ten patients (42% [80% CI, 28%-57%]) experienced CLTs. Trabectedin C max , half-life, clearance, and distribution volume were 1.28 ng/mL (standard deviation [SD], 0.58 ng/mL), 26.70 hours (SD, 9.09 hours), 39.98 L/h/m 2 (SD, 14.08 L/h/m 2 ), and 1460 L/m 2 (SD, 561 L/m 2 ), respectively., Conclusion: Trabectedin can be administered safely to elderly patients with STS who are unfit to receive anthracyclines. Pharmacokinetics in the elderly population was superimposable to historical data., (© 2020 American Cancer Society.)

Background: Cancer trials involving multiple treatment lines substantially increase our understanding of therapeutic strategies. However, even when the primary end-point of these studies is progression-free survival (PFS), their statistical analysis usually focuses on each line separately, or does not consider repeated events, thus missing potentially relevant information. Consequently, the evaluation of the effectiveness of treatment strategies is highly impaired., Methods: We evaluated the potentially different effect of bevacizumab (B) administered for the first- or second-line treatment of metastatic colorectal cancer (mCRC) in the ITACa (Italian Trial in Advanced Colorectal Cancer) randomized trial. The ITACa trial consisted of two arms: first-line chemotherapy (CT)+B followed by second-line CT alone versus first-line CT alone followed by second-line CT+B or CT+B+cetuximab according to KRAS status. Cox models for repeated disease progression were performed, and potential selection bias was adjusted using the inverse probability of censoring weighting method. Hazard ratios (HR) [95% confidence interval (CI)] for PFS (primary endpoint) were reported., Results: The overall effect of B across the two lines resulted in a HR = 0.80 (95% CI 0.68-0.95, p  = 0.008). Evaluating the differential effect of B in first- and second-line, the addition of B to first-line chemotherapy (CT) produced a 10% risk reduction (HR = 0.90, 95% CI 0.72-1.12, p  = 0.340) versus CT alone; B added to second-line CT produced a 36% risk reduction (HR = 0.64, 95% CI 0.49-0.84, p  = 0.0011) versus CT alone., Conclusion: Our results seem to suggest that B confers a PFS advantage when administered in combination with second-line chemotherapy, which could help to improve current international guidelines on optimal sequential treatment strategies., Competing Interests: Conflict of interest statement: The authors declare that there is no conflict of interest., (© The Author(s), 2020.)

Background: Immune checkpoint inhibitors (ICIs) reported remarkable achievements in several solid tumours. However, in metastatic colorectal cancer (mCRC) promising results are limited to patients with deficient mismatch repair/microsatellite instability-high (dMMR/MSI-high) tumours due to their immune-enriched microenvironment. Combining cytotoxic agents and bevacizumab in mCRC with proficient mismatch repair/microsatellite stability (pMMR/MSS) could make ICIs efficacious by increasing the exposure of neoantigens, especially with highly active chemotherapy regimens, inducing immunogenic cell death, increasing the tumoral infiltration of CD8+ T-cells and reducing tumour-associated myeloid-derived suppressor cells. VEGF-blockade also plays an immunomodulatory role by inhibiting the expansion of T regulatory lymphocytes. Consistently with this rationale, a phase Ib study combined the anti-PDL-1 atezolizumab with FOLFOX/bevacizumab as first-line treatment of mCRC, irrespective of microsatellite status, and reported interesting activity and efficacy results, without safety concerns. Phase III trials led to identify FOLFOXIRI plus bevacizumab as an upfront therapeutic option in selected mCRC patients. Drawing from these considerations, the combination of atezolizumab with an intensified upfront treatment (FOLFOXIRI) and bevacizumab could be worthy of investigation., Methods: AtezoTRIBE is a prospective, open label, phase II, comparative trial in which initially unresectable and previously untreated mCRC patients, irrespective of microsatellite status, are randomized in a 1:2 ratio to receive up to 8 cycles of FOLFOXIRI/bevacizumab alone or in combination with atezolizumab, followed by maintenance with bevacizumab plus 5-fluoruracil/leucovorin with or without atezolizumab according to treatment arm until disease progression. The primary endpoint is PFS. Assuming a median PFS of 12 months for standard arm, 201 patients should be randomized in a 1:2 ratio to detect a hazard ratio of 0.66 in favour of the experimental arm. A safety run-in phase including the first 6 patients enrolled in the FOLFOXIRI/bevacizumab/atezolizumab arm was planned, and no unexpected adverse events or severe toxicities were highlighted by the Safety Monitoring Committee., Discussion: The AtezoTRIBE study aims at assessing whether the addition of atezolizumab to an intensified chemotherapy plus bevacizumab might be an efficacious upfront strategy for the treatment of mCRC, irrespective of the microsatellite status., Trial Registration: AtezoTRIBE is registered at Clinicaltrials.gov ( NCT03721653 ), October 26th, 2018 and at EUDRACT (2017-000977-35), Februray 28th, 2017.

Introduction: Patients with metastatic or locally advanced, non-resectable, grade 3 poorly differentiated gastroenteropancreatic (GEP) and lung neuroendocrine carcinomas (NECs) are usually treated with in first-line platinum compounds. There is no standard second-line treatment on progression. Accurate biomarkers are needed to facilitate diagnosis and prognostic assessment of patients with NEC., Methods and Analysis: The SEcond-line therapy in NEuroendocrine CArcinomas (SENECA) study is a randomised, non-comparative, multicentre phase II trial designed to evaluate the efficacy and safety of folinic acid, 5-fluorouracil and irinotecan (FOLFIRI) or capecitabine plus temozolomide (CAPTEM) regimens after failure of first-line chemotherapy in patients with lung NEC and GEP-NEC. Secondary aims are to correlate the serum miRNA profile and primary mutational status of MEN1, DAXX, ATRX and RB-1 with prognosis and outcome and to investigate the prognostic and predictive role of the Ki-67 score and 18-fluorodeoxyglucose positron emission tomography/computed tomography ( 18 F-FDG PET/CT) or 68 Ga-PET/CT. The main eligibility criteria are age ≥18 years; metastatic or locally advanced, non-resectable, grade 3 lung or GEP-NECs; progression to first-line platinum-based chemotherapy. A Bryant and Day design taking into account treatment activity and toxicity was used to estimate the sample size. All analyses will be performed separately for each treatment group in the intention-to-treat population. A total of 112 patients (56/arm) will be randomly assigned (1:1) to receive FOLFIRI every 14 days or CAPTEM every 28 days until disease progression or unacceptable toxicity or for a maximum of 6 months. Patients undergo testing for specific biomarkers in primary tumour tissue and for miRNA in blood samples. MiRNA profiling will be performed in the first 20 patients who agree to participate in the biological substudy., Ethics and Dissemination: The SENECA trial, supported by Istituto Scientifico Romagnolo per lo Studio e la Cura dei Tumori (IRST), was authorised by the locals Ethics Committee and the Italian Medicines Agency (AIFA). Results will be widely disseminated via peer-reviewed manuscripts, conference presentations and reports to relevant authorities.The study is currently open in Italy., Trail Registration Number: NCT03387592; Pre-results.

Background: Although American Society of Clinical Oncology and European Society for Medical Oncology guidelines have identified the negative prognostic factors that clinicians have to consider when treating their patients with stage II colon cancer (CC), the role of histological subtype is controversial., Subjects, Materials, and Methods: The randomized, multicenter, phase III TOSCA trial compared 3 versus 6 months of fluoropyrimidine-oxaliplatin adjuvant chemotherapy in 3,759 patients with high-risk stage II or stage III CC. The objective of this substudy was to evaluate the influence of histological subtypes on the impact of the treatment duration of adjuvant chemotherapy in terms of relapse-free survival (RFS) and overall survival (OS) in 85 mucinous adenocarcinoma (MUC) and 389 nonmucinous adenocarcinoma (NMUC) patients with high-risk stage II, grade 3 CC., Results: A significant interaction between treatment duration and histology was observed in both RFS (p = .027) and OS (p = .017). In the subgroup of patients with MUC, worse RFS (adjusted hazard ratio [HR], 3.95; 95% confidence interval [CI], 1.03-15.17; p = .045) and OS (HR, 9.56; 95% CI, 1.14-79.98; p = .037) were detected for patients treated in the 3-month arm. No statistically significant differences were found in the subgroup of patients with NMUC., Conclusion: Patients with MUC, grade 3, stage II CC require special attention and may need 6 months of oxaliplatin-based chemotherapy. Larger studies are required to assess the combined use of histology and other prognostic/predictive factors to define the administration of chemotherapy in patients with stage II CC and to improve their prognosis., Implications for Practice: Although ASCO and ESMO guidelines define the prognostic factors for patients with stage II colon cancer to establish the use of adjuvant chemotherapy, the influence of histological subtypes is controversial in this population. This study underscores that patients with grade 3 mucinous adenocarcinomas may need adjuvant chemotherapy with oxaliplatin and fluoropyrimidines for a duration of 6 months rather than 3 months., (© AlphaMed Press 2020.)

Objective: Neoadjuvant chemotherapy plus interval debulking surgery is growing treatment strategy for advanced ovarian cancer patients with unresectable disease. Here, we aimed to assess predictors of surgical unresectability and survival of patients submitted to neoadjuvant chemotherapy plus interval debulking surgery., Methods: Data of consecutive 193 patients undergoing neoadjuvant chemotherapy plus interval debulking surgery were retrospectively evaluated in four Italian oncologic centers. RECIST 1.1 guidelines were used to assess response to neoadjuvant chemotherapy. Survival outcomes were evaluated using Kaplan-Meier and Cox proportional hazard models., Results: Overall, 155 (80.3%) and 38 (19.7%) patients had optimal and non-optimal cytoreduction at the time of interval debulking surgery. Via multivariate analysis, age (OR: 2.87 (95%CI: 1.29, 6.36) per 10-year increase) and radiological response to neoadjuvant chemotherapy (OR: 48.1 (95%CI: 6.33, 365.3)) impact on the inability to perform a complete cytoreduction. Patients having complete or partial response experienced a significant better disease-free survival than patients having stable or progressive disease at radiological examination (median disease-free survival 16.8 vs. 11.0 months; HR: 0.42 (95%CI: 0.09, 0.78); p = .001). Radiological response did not predict for overall survival (p = .719)., Conclusions: RECIST1.1 response criteria might be helpful to predict surgical resectability and disease-free survival of advanced stage ovarian cancer patients undergoing neoadjuvant chemotherapy plus interval debulking surgery., (Copyright © 2019.

Background: Platinum/fluoropyrimidine regimens are the backbone of first-line chemotherapy for advanced gastric cancer (AGC). However response rates to first line chemotherapy range from 30 to 50% and disease progression occurs after 4-6 cycles. The optimal duration of first-line therapy is still unknown and its continuation until disease progression represents the standard. However this strategy is often associated with cumulative toxicity and rapid development of drug resistance. Moreover, only about 40% of AGC pts. are eligible for second-line treatment., Methods: This is a randomized, open-label, multicenter phase III trial. It aims at assessing whether switch maintenance to ramucirumab plus paclitaxel will extend the progression-free survival (PFS) of subjects with HER-2 negative AGC who have not progressed after 3 months of a first-line with a platinum/fluoropyrimidine regimen (either FOLFOX4, mFOLFOX6 or XELOX). The primary endpoint is to compare Progression-Free Survival (PFS) of patients in ARM A (switch maintenance to ramucirumab and placlitaxel) versus ARM B (continuation of the same first-line therapy with oxaliplatin/fluoropyrimidine). Secondary endpoints are: overall survival, time-to-treatment failure, overall response rate, duration of response, percentage of patients that will receive a second line therapy according to arm treatment, safety, quality of life. Exploratory studies including Next-Generation Sequencing (NGS) in archival tumor tissues are planned in order to identify potential biomarkers of primary resistance and prognosis., Discussion: The ARMANI study estimates if patients treated with early swich with ramucirumab plus paclitaxel received benefit when compared to those treated with continuation of first line therapy. The hypothesis is that the early administration of an active, non-cross resistant second-line regimen such as ramucirumab plus paclitaxel may prolong the time in which patients are progression-free, and consequently have a better quality of life. Moreover, this strategy may rescue all those subjects that become ineligible for second-line therapy due to the rapid deterioration of health status after the first disease progression., Trial Registration: ARMANI is registered at ClinicalTrials.gov ( NCT02934464 , October 17, 2016) and EudraCT(2016-001783-12, April 202,016).

Objectives: Brain metastases are common among patients with non-squamous non-small-cell lung cancer (NSCLC) and result in a poor prognosis. Consequently, such patients are often excluded from clinical trials. In Italy an expanded access program (EAP) was used to evaluate nivolumab efficacy and safety in this subpopulation outside a clinical trial., Materials and Methods: In this EAP, nivolumab was available for patients with non-squamous NSCLC in progression after at least one systemic treatment for stage IIIB/IV disease. Nivolumab 3 mg/kg was administered intravenously every 2 weeks. Patients with brain metastases could be included if they were asymptomatic, neurologically stable and either off corticosteroids or on a stable or decreasing dose of ≤10 mg/day prednisone., Results: 409 out of 1588 patients included had asymptomatic or controlled brain metastases. A median of 7 doses (range 1-45) were delivered. Median follow-up was 6.1 months (range 0.1-21.9). The disease control rate was 39%: 4 patients had a complete response, 64 a partial response and 96 showed stable disease. At baseline, 118 patients were on corticosteroids and 74 were undergoing concomitant radiotherapy. The median overall survival in this subpopulation was 8.6 months (95% CI: 6.4-10.8). 337 discontinued treatment for various reasons, 23 (7%) of whom due to adverse events, in line with that observed in the overall population and in previous studies., Conclusions: Our results confirm that nivolumab is active in non-squamous NSCLC patients with brain metastases, despite their poor prognosis. Its safety profile is also concordant with results in the EAP overall population and in patients with other malignancies., (Copyright © 2018 Elsevier B.V. All rights reserved.)

Objective: The aim of the study was to evaluate outcomes of patients with unresectable advanced ovarian cancer experiencing complete response (CR) to neoadjuvant chemotherapy., Methods: Data of consecutive patients undergoing neoadjuvant chemotherapy plus interval debulking surgery (IDS) were retrospectively reviewed in 4 Italian centers. Using a propensity-matching algorithm, we compared data of patients achieving CR with neoadjuvant chemotherapy (no macroscopic either microscopic residual disease (RD) at the time of IDS) with patients achieving partial response (PR). This latter group was stratified by the presence of RD (RD = 0 vs RD > 0)., Results: Overall, 193 had IDS after neoadjuvant chemotherapy: 25 (13%), 81 (41.9%), and 74 (38.3%) patients had CR, PR with RD of 0, and PR with RD of more than 0, respectively. In addition, 13 (6.7%) patients had no macroscopic disease detected at DS but just microscopic disease at pathological examination. For the study purpose, 25 patients achieving CR were matched (1:2) with 50 patients having PR and RD of 0 and 50 patients having PR and RD of more than 0. As the result of propensity matching, baseline characteristics were similar between groups. Comparing survival outcomes of patients having CR and PR with RD of 0, we observed that type of response to chemotherapy did not influence disease-free (hazard ratio = 1.53 [95% confidence interval = 0.88-2.66], P = 0.127) and overall (hazard ratio = 1.74 [95% confidence interval = 0.76-4.01], P = 0.189) survivals. Patients achieving CR experienced significantly better disease-free survival (P = 0.004) and a trend toward better overall survival (P = 0.06) than patients achieving PR with RD of more than 0 at IDS., Conclusions: Complete cytoreduction might mitigate the difference in response to neoadjuvant chemotherapy. The presence of RD at IDS is associated with worse survival outcomes.

Telomerase activity and telomere length are essential for the pathogenesis of several human diseases, including genitourinary tumors. Telomerase constitutes a complex system that includes human telomerase reverse transcriptase (hTERT), human telomerase RNA component (hTR) and telomerase associated protein 1 (TEP1), which are overexpressed in tumor cells compared to normal cells and are involved in the carcinogenesis and progression of renal cell carcinoma (RCC), bladder (BC) and prostate cancer (PCa). In addition, telomerase degraded peptide fragments expressed on the surface of tumor cells lead to their recognition by immune cells. On this scenario, in vitro and in vivo studies have shown effective anti-tumor activity of hTERT-tailored strategies in genitourinary tumors, including active immunotherapy with hTERT-peptide vaccines and passive immunotherapy with hTERT-transduced T cell infusion. This review emphasizes the role of telomerase in the carcinogenesis and progression of genitourinary tumors, thus underlying the potential of emerging telomerase-tailored immunotherapies in these patients., (Copyright © 2018.

Background: The aim of this study was to investigate the role of pre-treatment aspartate aminotransferase-lynphocyte ratio (ALRI) as a predictor of prognosis and treatment efficacy in patients with metastatic colorectal cancer (mCRC) enrolled in the prospective multicenter randomized ITACa (Italian Trial in Advanced Colorectal Cancer) trial to receive first-line chemotherapy (CT) + bevacizumab (B) or CT alone., Patients and Methods: Patients randomly received CT+B or CT alone as first-line therapy. CT consisted of either FOLFOX4 or FOLFIRI at the clinician's discretion., Results: Out of the 284 patients enrolled, increased ALRI levels were associated with shorter PFS and OS ( p <0.0001). At baseline, median PFS was 10.3 months (95% CI 9.4-12.0) and 8.0 months (95 % CI 6.8-8.9), and median OS was 25.2 months (95 % CI 21.3-30.2) and 18.8 months (95 % CI 16.6-21.7) for patients with low (<14) and high (≥14) ALRI levels, respectively (HR 1.43, 95% CI 1.12-1.82, p =0.004; HR=1.51, 95% CI 1.17-1.96, p <0.001). Interaction tests on ALRI levels and treatment efficacy in the CT+B and the CT groups were statistically significant for PFS ( p =0.0003), but not for OS ( p =0.228)., Conclusion: Our results indicate that ALRI is a good prognostic and predictive marker for mCRC patients candidate for CT+B., Competing Interests: Disclosure The authors report no other conflicts of interest in this work.

Background: Ramucirumab-alone or combined with paclitaxel-represents one of the main options for patients failing first-line treatment for advanced gastric cancer., Objective: The RAMoss study aimed to evaluate the safety and efficacy profile of ramucirumab in the "real-life setting"., Patients and Methods: Patients from 25 Italian hospitals started therapy consisting of ramucirumab 8 mg/kg i.v. d1,15q28 with or without paclitaxel 80 mg/m 2 i.v. d1,8,15q28. The primary endpoint was safety, and secondary endpoints were overall response rate (ORR), progression-free survival (PFS), and overall survival (OS)., Results: One hundred sixty-seven patients with disease progression on first-line therapy received ramucirumab as monotherapy (10%) or combined with paclitaxel (90%). Median treatment duration was 4 months (1-17 months). Global incidence of grade (G) 3-4 toxicity was 9.6%, and for neutropenia 5.4%; treatment was discontinued due to toxicity in 3% of patients. The most frequent adverse events (AE) were G1-2 fatigue (27.5%), G1-2 neuropathy (26.3%), and G1-2 neutropenia (14.9%). ORR was 20.2%. Stable disease was observed in 39.2% of patients, with a disease control rate of 59.4%. With a median follow-up of 11 months, median PFS was 4.3 months (95% confidence interval [CI] 4.1-4.7), whereas median OS was 8.0 months (95% CI: 7.09-8.9). In a multivariate analysis, ECOG performance status <1 or ≥1 (HR 1.13, 95% CI 1.0-1.27, p = 0.04) and the presence versus absence of peritoneal metastases (HR 1.57, 95% CI 1.63-2.39, p = 0.03) were independent poor prognostic factors., Conclusions: These "real-life" efficacy data on ramucirumab treatment are in line with previous randomized trials. Ramucirumab is well tolerated in daily clinical practice.

Objectives: Neoadjuvant chemotherapy (NACT) followed by interval debulking surgery (IDS) may be a valuable treatment option in advanced ovarian cancer when primary cytoreduction is not feasible. However, a consensus on the ideal number of NACT cycles is still lacking. In the present investigation, we aimed to evaluate how number of cycles of NACT influenced patients' outcomes., Methods: Data of consecutive patients undergoing NACT and IDS were retrospectively reviewed in 4 Italian centers, and survival outcomes were evaluated., Results: Overall, 193 patients were included. Cycles of NACT were 3, 4, and at least 5 in 77 (40%), 74 (38%), and 43 (22%) patients, respectively. Patients undergoing 3 cycles experienced a similar disease-free survival (hazard ratio [HR], 1.12; 95% confidence interval [CI], 0.89-1.65; P = 0.20) but an improved overall survival (HR, 1.64; 95% CI, 1.05-2.4; P = 0.02) in comparison to patients receiving at least 4 cycles. Five-year overall survival was 46% and 31% for patients having 3 and at least 4 cycles. Ten-year overall survival was 26% and 18% for patients having 3 and at least 4 cycles (HR, 1.70; 95% CI, 1.13-2.55; P = 0.009). Using multivariate analysis, we observed that only Eastern Cooperative Oncology Group performance status correlated with overall survival (HR, 1.76; 95% CI, 1.2-2.49; P = 0.001). In addition, a trend toward worse overall survival was observed for patients with residual disease at IDS (HR, 1.29; 95% CI, 0.98-1.70; P = 0.06) and patients receiving at least 4 cycles (HR, 1.76; 95% CI, 0.95-3.22; P = 0.06)., Conclusion: Our data underline the potential implication of number of cycles of NACT before IDS. Further prospective studies are warranted to assess this correlation.

Background: Brain metastases (BM) from epithelial ovarian cancer (EOC) are considered a rare and unfavourable event. There is no consensus regarding the best management of these patients., Methods: A multicenter retrospective analysis of patients with BM from EOC treated between 1997 and 2014 in 18 institutions of the MITO (Multicenter Italian Trials in Ovarian cancer) group was conducted. Univariate and multivariate analysis were performed., Results: A total of 174 women were identified as having BM from EOC. The median time interval between primary diagnosis of EOC and occurrence of BM was 26months (range 2-129months). The median overall survival from primary EOC diagnosis was 48months (95% CI 39.5-56.4months) and from diagnosis of BM was 12months (95% CI 9.6-14.3months). The majority of enrolled women (81.7%) were classified as sensitive to platinum-based chemotherapy. Four variables were significantly associated with poor overall survival in multivariate analysis: multiple BM [HR: 1.86 (95% CI: 1.22-2.84)], presence of extracranial disease [HR: 1.77 (95% CI: 1.11-2.83)] age [HR: 1.74 (95% CI: 1.17-2.59)], and monotherapy [HR: 2.57 (95% CI: 1.64-3.86)]. On the contrary, residual tumor at primary surgery, FIGO stage at primary diagnosis and platinum sensitivity were found to have no significant impact on survival from diagnosis of brain lesions., Conclusions: Our results suggest that BM is a rare and late manifestation of EOC, with a 12-month life-span expectation. Multiple approach is a positive independent prognostic factor and should be proposed to carefully selected patients., (Copyright © 2016. Published by Elsevier Inc.)

Epidermal growth factor receptor (EGFR) is usually expressed in squamous cell anal carcinoma (SCAC) and anti-EGFR agents could represent a valid treatment strategy, also considering that KRAS and BRAF mutations are rare events in this type of cancer. However, no data are available on NRAS status in SCAC. In this study we analyzed NRAS status (exons 2-4) by Pyrosequencing in a case series of 50 SCAC patients previously characterized in our laboratory for KRAS, BRAF, PIK3CA mutations and HPV and HIV infections. We found no mutation in NRAS gene. These results confirm that since the principal anti-EGFR resistance mechanisms are almost absent in SCAC, anti-EGFR agents should be considered for the treatment of this type of cancer.

Background: No biomarker is available to predict prognosis of patients with advanced ovarian cancer (AOC) and guide the choice of chemotherapy. We performed a prospective-retrospective biomarker study within the MITO2 trial on the treatment of AOC., Patients and Methods: MITO2 is a randomised multicentre phase 3 trial conducted with 820 AOC patients assigned carboplatin/paclitaxel (carboplatin: AUC5, paclitaxel: 175 mg/m², every 3 weeks for 6 cycles) or carboplatin/PLD-pegylated liposomal doxorubicin (carboplatin: AUC5, PLD: 30 mg/m², every 3 weeks for 6 cycles) as first line treatment. Sixteen biomarkers (pathways of adhesion/invasion, apoptosis, transcription regulation, metabolism, and DNA repair) were studied in 229 patients, in a tissue microarray. Progression-free and overall survival were analysed with multivariable Cox model., Results: After 72 months median follow-up, 594 progressions and 426 deaths were reported; there was no significant difference between the two arms in the whole trial. No biomarker had significant prognostic value. Statistically significant interactions with treatment were found for DNA-dependent protein kinase (DNA-PK) and phosphorylated acetyl-coenzymeA carboxylase (pACC), both predicting worse outcome for patients receiving carboplatin/paclitaxel., Conclusion: These data show that in presence of DNA-PK or pACC overexpression, carboplatin/paclitaxel might be less effective than carboplatin/PLD as first line treatment of ovarian cancer patients. Further validation of these findings is warranted.

Background: To investigate the role of pre-treatment inflammatory indexes (II) as predictors of prognosis and treatment efficacy in patients with metastatic colorectal cancer mCRC randomized onto the prospective multicenter randomized ITACa (Italian Trial in Advanced Colorectal Cancer) trial to receive first-line chemotherapy (CT) with or without bevacizumab (Bev)., Results: In the overall population, PFS and OS were higher in patients with low SII (p = .015 and .002, respectively), low NLR (p = .0001 and <.0001, respectively) and low PLR (p = .004 and .008, respectively). Patients with low NLR in the CT plus Bev arm had a higher PFS than those treated with CT alone (HR = 0.69, p = .021)., Patients and Methods: Two hundred and eighty-nine patients were considered for this study, 141 receiving CT plus Bev and 148 receiving CT alone. The pre-treatment systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) were evaluated to identify a potential correlation with progression-free (PFS) and overall survival (OS) in both the overall population and the 2 treatment arms., Conclusion: Our results indicate that II, in particular NLR, are good prognostic and predictive markers for mCRC patients who are candidates for CT plus Bev., Competing Interests: CONFICTS OF INTEREST The authors have declared that no competing interests exist.
