Spotlight on bevacizumab in metastatic colorectal cancer: patient selection and perspectives

Abstract

Metastatic colorectal cancer (mCRC) is a prevalent disease for which combination cytotoxic chemotherapy is the mainstay of treatment. With the use of targeted therapy, including anti-angiogenic agents, there have been significant improvements in overall outcome of patients with mCRC. Bevacizumab, a monoclonal antibody targeting the vascular endothelial growth factor ligand A, is approved for use in mCRC patients in both the first and second lines of therapy. With a better understanding of the disease through molecular profiling, identification of prognostic biomarkers may lead to better patient selection with improved outcomes for those affected by this disease.
