Résumé
BACKGROUND: This prospective phase II study assessed the efficacy and safety of bevacizumab plus chemotherapy regimens commonly used in the second-line treatment of metastatic colorectal cancer (mCRC). METHODS: Patients with mCRC who progressed or relapsed after first-line oxaliplatin-based or irinotecan-based treatment received bevacizumab 2.5 mg/kg/week plus chemotherapy until disease progression. The primary endpoint was disease-control rate (DCR). Secondary endpoints included progression-free survival (PFS), overall survival (OS), objective response rate (ORR), and safety. RESULTS: Fifty-three patients (66% men; median age, 62 years old) received second-line bevacizumab plus folinic acid, fluorouracil, and irinotecan (FOLFIRI; 57%), folinic acid, fluorouracil, oxaliplatin (FOLFOX; 26%), irinotecan (15%), or capecitabine plus irinotecan (XELIRI; 2%). The DCR was 87% (95% CI, 77%-97%); ORR was 32% (95% CI, 19%-46%). Median PFS was 6.5 months (95% CI, 5.8-7.8 months) and median OS 19.3 months, (95% CI, 14.2-25.1 months).The most frequent grade 3/4 adverse events included neutropenia (21%), diarrhea (15%), asthenia, and vomiting (9% each). Five patients (9%) had grade 3/4 targeted toxicities: grade 3 hypertension (n = 2), grade 3 venous thromboembolism (n = 2), and grade 4 arterial thromboembolism (n = 1). None of these events led to death during the study. CONCLUSION: Bevacizumab plus standard second-line chemotherapy is highly active in patients with mCRC and has an acceptable safety profile.
