Hepatic resection for metastatic colorectal adenocarcinoma: a proposal of a prognostic scoring system11No competing interests declared.

Abstract

The proposed risk-score grading predicted the survival differences extremely well. Estimated survival as determined by the Cox proportional hazards model was similar to that determined by the Kaplan-Meier method. Verification and further improvements of the proposed system are awaited by other centers or international collaborative studies.
