Bevacizumab with chemotherapy in patients with KRAS wild-type metastatic colorectal cancer: Czech registry data

Future Oncol. 2015;11(2):225-32. doi: 10.2217/fon.14.240.

Abstract

Aim: This retrospective analysis investigated the effectiveness of combination therapy with bevacizumab and chemotherapy in the first-line treatment of patients with KRAS wild-type metastatic colorectal cancer.

Patients & methods: Patients with KRAS wild-type metastatic colorectal cancer in the CORECT registry who initiated treatment with bevacizumab between 2008 and 2012 were enrolled. Overall survival and progression-free survival were the main effectiveness end points.

Results: A total of 981 patients were enrolled. Median progression-free survival was 11.3 months (95% CI: 10.7-11.8) and median overall survival was 28.4 months (95% CI: 26.2-30.6). The most common adverse events were thromboembolic disease (4%) and hypertension (3.5%).

Conclusion: This retrospective analysis shows the effectiveness of bevacizumab with chemotherapy in patients with KRAS wild-type metastatic colorectal cancer.

Keywords: KRAS; bevacizumab; chemotherapy; colorectal cancer.
