Background
The addition of bevacizumab to standard chemotherapy has significant clinical benefits in metastatic colorectal cancer. However, its use is often avoided due to patient condition or disease status.
Methods
Of 228 consecutive patients receiving first-line FOLFOX-based regimens from June 2007 to June 2009, 96 patients (42 %) received FOLFOX alone without bevacizumab. We retrospectively examined the reasons why bevacizumab was not combined with FOLFOX.
Results
Among 96 patients for whom the addition of bevacizumab was avoided, 73 patients (76 %) had bevacizumab-related contraindications including hypertension, proteinuria, bleeding, thromboembolic events, wound-healing complications and gastrointestinal perforation. Other avoidance reasons were conditions precluding the use of bevacizumab in 15 patients (16 %), economic problems and anxiety about adverse events in 8 patients (8 %), and unknown reasons in 3 patients.
Conclusions
Bevacizumab-related contraindications were the main reason for drug avoidance, though economic problems and anxiety about rare but serious adverse events were also factors for avoidance of bevacizumab.
