摘要
Objectives: A phase II study was carried out to assess the efficacy and toxicity of combination chemotherapy with irinotecan, 5-fluorouracil (5-FU), and leucovorin (FOLFIRI) for the treatment of patients with metastatic or recurring gastric cancer previously treated with fluoropyrimidine-based chemotherapy.
Methods: Eligible patients were those who had metastatic gastric cancer previously treated with a fluoropyrimidine-based chemotherapy regimen or had disease recurrence within 6 months of completing adjuvant fluoropyrimidine-containing chemotherapy. Participants received irinotecan (150 mg/m(2) on day 1) and leucovorin (LV; 20 mg/m(2) on days 1-2) followed by continuous infusion of 5-FU (1500 mg/m(2) on days 1-2), every 2 weeks.
Results: Between April 2006 and March 2008, 33 patients were enrolled in the study. FOLFIRI served as a second-line treatment in 27 patients, third-line treatment in 4 patients, and fourth-line treatment in 2 patients. The patients had a median age of 60 years (range, 40-75) and underwent 132 cycles of chemotherapy, with a median of 3 cycles (range, 1-15) per patient. The response rate was 18.2%, and the disease control rate was 36%. Median overall survival was 5.1 months (95% confidence interval, 3.74-6.45), and median time to progression was 2.3 months (95% confidence interval, 1.81-2.78). The major grade 3-4 toxicity was neutropenia (45.4%).
Conclusion: Combination chemotherapy with irinotecan, 5-FU, and LV is feasible in gastric cancer patients previously treated with fluoropyrimidine-based chemotherapy.
