A Study to Assess the Impact of Sarcopenia on the Outcomes of Colorectal Cancer Patients Treated With Chemotherapy Combined With Bevacizumab

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to explore the relationship between sarcopenia, as defined by computed tomography, treatment related outcomes and other body composition related parameters in a patient population receiving bevacizumab beyond progression.
