摘要
Since 2007, S-1 plus cisplatin therapy has been recognized as the standard first-line treatment for advanced gastric cancer in Japan. However, no standard regimen has been established for patients refractory to first-line treatment. Furthermore, irinotecan and paclitaxel are considered key drugs for second-line treatment. Several studies have investigated the efficacy and tolerability of combination therapy with oxaliplatin, 5-fluorouracil and leucovorin (modified FOLFOX-6) for advanced gastric cancer. Here, we examined the efficacy and toxicity of modified FOLFOX-6 therapy in heavily pretreated patients with advanced gastric cancer refractory to 5-fluorouracil, irinotecan, cisplatin and taxanes.
Fourteen patients with advanced gastric cancer refractory to 5-fluorouracil, irinotecan, cisplatin and taxanes were included in the study. In modified FOLFOX-6 therapy, 85 mg/m(2) oxaliplatin, 400 mg/m(2) 5-fluorouracil and 200 mg/m(2) leucovorin on Day 1 were administered biweekly by intravenous infusion, followed by the administration of 2400 mg/m(2) 5-fluorouracil by a 46-h continuous infusion.
The median age of the patients was 59 years (range, 2274). A median of 5.5 (range, 113) chemotherapy cycles were administered. The overall response rate was 23.1 in patients with measurable lesions. Of the 12 patients with advanced gastric cancer refractory to cisplatin, 2 showed partial response (response rate, 18.2). The progression-free survival was 90 days, and the median survival time from the initiation of modified FOLFOX-6 therapy was 268 days. Grade 34 toxicities most commonly observed included neutropenia (57), anaemia (14), thrombocytopenia (21) and hyperammonaemia (7).
Modified FOLFOX-6 therapy in patients refractory to 5-fluorouracil, irinotecan, cisplatin and taxanes may be a potential advanced gastric cancer therapeutic strategy.
