摘要
This study aimed at assessing the efficacy and safety of biweekly oxaliplatin in combination with continuous infusional 5-fluorouracil and leucovorin (modified FOLFOX regimen) in patients with advanced small bowel adenocarcinoma (SBA). Thirty-three eligible patients with previously untreated SBA received 85 mg/m(2) of oxaliplatin intravenously over a 2-h period on day 1, together with 400 mg/m(2) of leucovorin over 2 h, followed by a 46-h infusion of 5-FU 2600 mg/m(2) every 2 weeks. All patients were evaluable for efficacy and toxicity. A median of nine cycles (range 3-18) was administered. The objective response rate was 48.5% [95% confidence interval (95% CI): 31-67%], with one complete response, 15 partial responses, 12 stable diseases, and five progressions. The median time to progression was 7.8 months (95% CI: 6.0-9.6) and the median overall survival was 15.2 months (95% CI: 11.0-19.4). Toxicity was fairly mild. Grade 3 toxicities included neutropenia (12.1%), thrombocytopenia (3.0%), nausea (6.1%), vomiting (3.0%), diarrhea (3.0%), peripheral neuropathy (9.1%), and fatigue (3.0%), and grade 4 toxicities occurred in none of the patients. The modified FOLFOX regimen is highly active and well tolerated as first-line chemotherapy for advanced SBA patients.
