(HealthDay) -- Continuing use of bevacizumab (Avastin) in combination with second-line chemotherapy improves overall survival (OS) and progression-free survival (PFS) in patients with metastatic colorectal cancer (mCRC) who have progressed after discontinuation of first-line bevacizumab and chemotherapy, according to the results of a phase III study presented at the annual meeting of the American Society of Clinical Oncology, held from June 1 to 5 in Chicago.
