Abstract
PURPOSE
S-1 or capecitabine plus oxaliplatin are considered active and tolerable in gastric cancer patients. We conducted a randomized phase II trial in gastric cancer patients to compare the activity and safety of these combinations.
METHODS
The patients received S-1 at 80 mg/m2 for 14 days, followed by a 7-day rest period within a 3-week schedule in the S-1/oxaliplatin (SOX) arm, and capecitabine at 2000 mg/m2 for 14 days, followed by a 7-day rest period within a 3-week schedule in the capecitabine/oxaliplatin (CAPOX) arm. Oxaliplatin 130 mg/m2 was administered every 3 weeks in both arms.
RESULTS
One hundred twenty-nine patients were randomly assigned to SOX (N=65) or CAPOX (N=64). The median time to progression and the overall survival were 6.2 and 12.4 months with SOX, respectively; and 7.2 and 13.3 months with CAPOX, respectively. The overall response rates were 40% and 44% for SOX and CAPOX, respectively. The most frequent grade 3 or 4 toxicities were thrombocytopenia (15.4%) for SOX and neutropenia (18.8%) for CAPOX. The median time to 10% deteriorations in global health scores was similar in both arms (SOX, 4.3 months, CAPOX, 4.9 months).
CONCLUSION
Both the SOX and CAPOX regimens were equally active and well tolerated in advanced gastric cancer patients.
