Key clinical point: Combination of bevacizumab with S-1 and irinotecan vs 5-fluorouracil, leucovorin, and oxaliplatin (mFOLFOX6)/capecitabine and oxaliplatin (CapeOX) as the first-line treatment for metastatic colorectal cancer (mCRC) showed comparable overall survival and noninferior progression-free survival (PFS).
Major finding: During a median follow-up of 48.7 months, median survival and PFS in patients assigned to bevacizumab+mFOLFOX6/CapeOX vs bevacizumab+S-1/irinotecan were 32.6 months vs 34.3 months (hazard ratio [HR], 0.89; P = .293) and 10.8 months vs 14.0 months (HR, 0.86; P less than .0001 for noninferiority), respectively. Safety results were as reported previously.
Study details: Findings are from phase 3 TRICOLORE trial including 487 patients with previously untreated mCRC who were randomly assigned to receive bevacizumab+mFOLFOX6/CapeOX or bevacizumab+S-1 and irinotecan.
