Validation of the Classification for Resectability and Ablatability Criteria for the Treatment of Liver Only Colorectal Metastases

The aim of this study is to validate a proposed classification system regarding overall survival as well as a comparison with patients with liver metastases and extrahepatic metastasis of colorectal cancer. The study also aims to identify the proportion of patients in each group, the proportion of patients converted from 4c to 4b and to compare survival to the patients only treated with chemotherapy.
