Purpose: This phase II trial assessed the tolerability and efficacy of a triplet of oxaliplatin, irinotecan, and fluorouracil/folinic acid in advanced gastric cancer.
Methods: Patients with unresectable or metastatic gastric cancer, unexposed to palliative chemotherapy, received oxaliplatin 85 mg/m(2) iv and irinotecan 150 mg/m(2) iv on day 1, 6S-folinic acid 250 mg/m(2) iv and fluorouracil 750 mg/m(2) iv on day 2, every 2 weeks. Response rate (RR) was assessed after a minimum of four cycles, and treatment continued up to 12 cycles.
Results: Sixty-three patients were treated, with a median of eight (range 1-12) cycles/patient. Two complete and 19 partial responses were registered (RR 33% [95% CI, 22-46%]). Median progression-free survival was 7.5 (95% CI, 5.6-9.4) months, and median overall survival was 12.1 (95% CI, 10.8-13.4) months. Most common grade > or =3 toxicities were neutropenia (59%), febrile neutropenia (7%), vomiting (20%), and diarrhoea (10%). All-grade neurotoxicity affected 33% of patients.
Conclusions: Oxaliplatin, irinotecan, and fluorouracil/folinic acid administered every 2 weeks are safe and active in advanced gastric cancer.

Pancreatic cancer is a highly aggressive malignancy with the majority of patients presenting at a late stage with unresectable or metastatic disease. Even with first line treatment, median survival is approximately 11 months in patients with advanced PDAC. This report details the unique case of a patient that presented with peritoneal metastases from an adenocarcinoma of the body of the pancreas, had a remarkable response to palliative chemotherapy and is alive without evidence of disease 12 months following cessation of all active treatment.

Importance: Despite the high prevalence of KRAS alterations in pancreatic ductal adenocarcinoma (PDAC), the clinical impact of common KRAS mutations with different cytotoxic regimens is unknown. This evidence is important to inform current treatment and provide a benchmark for emergent targeted KRAS therapies in metastatic PDAC.
Objective: To assess the clinical implications of common KRAS G12 mutations in PDAC and to compare outcomes of standard-of-care multiagent therapies across these common mutations.

Background: The phase III NAPOLI-3 trial, which upgraded FOLFIRINOX (leucovorin, fluorouracil, irinotecan and oxaliplatin) to NALIRIFOX (liposomal irinotecan, oxaliplatin, leucovorin, and fluorouracil), demonstrated the superiority of NALIRIFOX over GEMNABP (gemcitabine and nab-paclitaxel) as the first-line treatment for metastatic pancreatic ductal adenocarcinoma. The purpose of this study was to assess the cost-effectiveness of NALIRIFOX, FOLFIRINOX, and GEMNABP, and to simulate the price of liposomal irinotecan at which NALIRIFOX could achieve cost-effectiveness.
Methods: A partitioned survival model was performed to evaluate the cost-effectiveness of NALIRIFOX, FOLFIRINOX and GEMNABP from the perspective of the Chinese healthcare system.

Background: Pancreatic ductal adenocarcinoma (PDAC) remains one of the most lethal malignancies, with limited treatment options yielding poor outcomes. This study aimed to evaluate the real-world clinical characteristics, treatment patterns, and outcomes of patients with locally advanced unresectable and de-novo metastatic PDAC in Saudi Arabia, providing regional data to compare with international benchmarks.
Methods: This is a retrospective, multicentre study involving 350 patients diagnosed with unresectable locally advanced or de-novo metastatic PDAC between January 2015 and November 2023.

Introduction: The standard of care for stage III colon cancer is 3 or 6 months of double-drug regimen chemotherapy following radical surgery. However, patients with positive circulating tumour DNA (ctDNA) exhibit a high risk of recurrence risk even if they receive standard adjuvant chemotherapy. The potential benefit of intensified adjuvant chemotherapy, oxaliplatin, irinotecan, leucovorin and fluoropyrimidine (FOLFOXIRI), for ctDNA-positive patients remains to be elucidated.
