概要 | BACKGROUND:We evaluated the efficacy and safety of S-1 plus oxaliplatin (SOX) as an alternative to cisplatin plus S-1 (CS) in first-line chemotherapy for advanced gastric cancer (AGC).PATIENTS AND METHODS:In this randomized, open-label, multicenter phase III study, patients were randomly assigned to receive SOX (80-120 mg/day S-1 for 2 weeks with 100 mg/m(2) oxaliplatin on day 1, every 3 weeks) or CS (S-1 for 3 weeks withPATIENTS AND METHODS:60 mg/m(2) cisplatin on day 8, every 5 weeks). The primary endpoints were non-inferiority in progression-free survival (PFS) and relative efficacy in overall survival (OS) for SOX using adjusted hazard ratios (HR) with stratification factors; performance status and unresectable or recurrent (+adjuvant chemotherapy) disease.RESULTS:Overall, 685 patients were randomized from January 2010 to October 2011. In per-protocol population, SOX (n=318) was non-inferior to CS (n=324) in PFS (median, 5.5 versus 5.4 months; HR 1.004, 95% confidence interval [CIRESULTS:]RESULTS:0.840-1.199; predefined non-inferiority margin 1.30). The median OS for SOX and CS were 14.1 and 13.1 months, respectively (HR 0.958 with 95% CI 0.803-1.142). In the intention to treat population (SOX, n=339; CS, n=337), the HRs in PFS and OS were 0.979 (95% CI 0.821-1.167) and 0.934 (95% CI 0.786-1.108), respectively. The most common ≥grade 3 adverse events (SOX versus CS) were neutropenia (19.5% versus 41.8%), anemia (15.1% versus 32.5%), hyponatremia (4.4% versus 13.4%), febrile neutropenia (0.9% versus 6.9%), and sensory neuropathy (4.7% versus 0%).CONCLUSION:SOX is as effective as CS for AGC with favorable safety profile, therefore SOX can replace CS. |
