Margin Status is Still an Important Prognostic Factor in Hepatectomies for Colorectal Liver Metastases: A Propensity Score Matching Analysis

摘要

The width of resection margin is still a matter of debate in case of colorectal liver metastasis resection. The aim of this study was to determine the risk factors for R1 resection. Once risk factors had been identified, patients were matched according to Fong's prognostic criteria, in order to evaluate whether R1 resection still remained a negative prognostic factor impacting overall and disease-free survival.
