Background: The prognosis of patients with advanced gastric cancer (AGC) remains poor, and no single chemotherapy regimen is recognized as a global standard. A phase II trial was conducted to determine the efficacy and tolerability of capecitabine and oxaliplatin (XELOX) given every 3 weeks in combination in patients with AGC. Methods: Patients with previously untreated AGC received intravenous oxaliplatin 130 mg/m2 over 2 h on day 1 plus oral capecitabine 1,000 mg/m2 twice daily on days 1–14, every 3 weeks. Treatment was continued for 8 cycles or until disease progression or intolerable toxicity. Results: Fifty patients were enrolled. In total, 210 cycles of XELOX were delivered. The OVERALL response rate was 42% (95% CI 28.6–56.7), with 2 complete and 19 partial responses. At 15.2 months of median follow-up, median time to progression and overall survival were 5.8 (95% CI 3.4–8.2) and 11.1 (95% CI 5.6–16.5) months, respectively. The most common hematological adverse event was neutropenia (56% of patients); grade 3–4 neutropenia was observed in 6 patients, with neutropenic fever in only 2 patients. The most common non-hematological toxicities were vomiting (34%), hand-foot syndrome (26%), diarrhea (24%) and neurosensory toxicity (22%). There were no treatment-related deaths. Conclusions: XELOX is active for the first-line treatment of AGC with a manageable tolerability profile. Copyright © 2010 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]

Background: To evaluate the efficacy and toxicity of an oxaliplatin, fluorouracil (5-FU), and folinic acid (FOLFOX-6) combination therapy in patients with advanced or recurrent gastric cancer. Methods: Patients with previously untreated advanced or recurrent gastric cancer received oxaliplatin 100 mg/m2 and leucovorin 400 mg/m2 (2-hour intravenous infusion) followed by a 5-FU bolus of 400 mg/m2 (10-min infusion) and then 5-FU 2,600–3,000 mg/m2 (46-hour continuous infusion). The chemotherapy was repeated every 14 days. Results: Fifty-one patients were enrolled in this study. Of these, 46 were assessable for efficacy, and all patients were assessable for toxicity. Three of 51 patients achieved a complete response, and 18 had partial responses, giving an overall response rate of 41.2%. Stable disease was observed in 11 (21.6%) patients and progressive disease in 14 (27.5%). The median time to progression was 5.4 months, and the median overall survival was 12.1 months. NCI-CTC grade 3/4 hematological toxicities were neutropenia and anemia in 9.8 and 7.8% of the patients, respectively. Grade 3 peripheral neuropathy was recorded in 3 (5.9%) patients. Other NCI-CTC grade 3 or 4 toxicities included diarrhea in 3 patients (5.9%) and vomiting in 5 (9.8%). There were no treatment-related deaths. Conclusions: This oxaliplatin/5-FU/folinic acid regimen shows good efficacy and an acceptable toxicity profile in advanced or recurrent gastric cancer patients; further clinical trials are warranted.
