[Bevacizumab in combination with mFOLFOX6 or FOLFIRI for previously treated metastatic colorectal cancer].
We retrospectively investigated the safety and efficacy on outpatient chemotherapy including bevacizumab(BV)as secondline therapy for inoperable metastatic colorectal cancer. Analytical subjects were thirty patients treated with chemotherapy including BV as second-line therapy after first disease progression. All patients were treated with BV 5mg/kg. Concurrent therapy was given mFOLFOX6(2 patients)and FOLFIRI(28 patients). The BV treatment frequency and all course treatment frequency including the prior regimens averaged 20 and 37 times, respectively. The overall response rate was 24. 1%(PR, 7 patients; SD, 17 patients; PD, 5 patients), and the median duration of progression-free survival was 8. 0 months. The median duration of survival after addition of BV was 20. 3 months. The adverse events were 84%(>grade 3, 9%), BV-associated adverse events were GI perforation(1 patient), GI hemorrhage(1 patient), grade 3 hypertension(1 patient)and grade 2 epitaxis(2 patient). Although it is necessary to be careful about GI hemorrhage and GI perforation, we could safely continue the treatment with BV on outpatient chemotherapy. We confirmed that the chemotherapy including BV as second-line therapy had high antitumor effect and patient benefit.
