The primary endpoint was overall response rate(ORR). Secondary endpoints were disease control rate(DCR), progression-free survival(PFS), overall survival(OS), and safety.RESULTS Among 74 patients treated in four French centers, nine were excluded due to prior use of aflibercept(n = 3), more than one prior treatment line in irinotecanna?ve patients(n = 3), and inadequate liver function(n = 3). In the "irinotecan-na?ve" patients(n = 30), ORR was 43.3% and DCR was 76.7%. Median PFS and OS were 11.3 mo(95%CI: 6.1-29.0) and 17.0 mo(95%CI: 13.0-17.3), respectively. The most common(> 5%) grade 3-4 adverse events were diarrhea(37.9%), neutropenia(14.3%), stomatitis and anemia(10.4%), and hypertension(6.7%). In the "pre-exposed irinotecan" patients(n = 35), 20(57.1%) received ≥ 2 prior lines of treatment. ORR was 34.3% and DCR was 60.0%. Median PFS and OS were 5.7 mo(95%CI: 3.9-10.4) and 14.3 mo(95%CI: 12.8-19.5), respectively.CONCLUSION Minimally modified FOLFIRI has improvement dramatically the FOLFIRI3-aflibercept efficacy, whatever prior use of irinotecan. A prospective randomized trial is warranted to compare FOLFIRI-aflibercept to FOLFIRI3-aflibercept.展开更多
