[Continuation of chemotherapy with bevacizumab for advanced and recurrent colorectal cancer].

We evaluated the association between the number of treatment courses with the concomitant use of bevacizumab(BV) and the reasons for discontinuation of the regimen in patients who received FOLFOX with or without BV as first-line chemotherapy and FOLFIRI with or without BV as second-line chemotherapy for advanced and recurrent colorectal cancer. In first-line treatment, 12 (2-46) and 10 (2-60) treatment courses were administered with and without BV, respectively, and this difference was not significant (p=0.60).
