Abstract | Introduction: Liver resection is the only curative treatment for colorectal liver metastasis. The identification of predictive factors leads to personalize patient management to enhance their long-term outcomes. This population-based study aimed to characterize factors associated with, and survival impact of patients who received hepatectomy for colorectal liver metastasis. Methods: A retrospective cohort study of all the hepatectomies for colorectal liver metastasis performed at third-level hospital of Spain (2010-2018) was conducted. The Kaplan-Meier method was used for survival analyses. Multivariable Cox and regression models were used to determine prognostic factors associated with overall survival. Results: The 5-year overall survival and disease-free survival were 42 and 33%, respectively. Survival analysis showed that metastasis features (number, largest size, distribution, and extrahepatic disease) and postsurgical factors (transfusion, major complications, and positive margin resection), as well as non-mutated KRAS, showed a significant association with survival. Otherwise, on multivariate analysis, only 5 independent risk factors were identified: major size metastasis >4 cm, RAS mutation, positive margin resection, intraoperative transfusion, and major complications. Conclusions: According to our findings, major size metastasis >4 cm, intraoperative transfusion, and major postoperative complications continue to be traditional prognostic factors. Meanwhile, the KRAS biomarker has a powerful impact as a survival prognostic factor. |
