Objectives:Treatment of metastatic colorectal cancer(mCRC)includes resection of liver metastases(LM),however,no validated biomarker identifies patients most likely to benefit from this *** meta-analysis aimed to assess the impact of the most relevant molecular alterations in cancer-related genes of CRC(i.e.,RAS,BRAF,SMAD4,PIK3CA)as prognostic markers of survival and disease recurrence in patients with mCRC surgically treated by LM ***:A systematic literature review was performed to identify studies reporting data regarding survival and/or recurrence in patients that underwent complete liver resection for CRC LM,stratified according to RAS,BRAF,PIK3CA,and SMAD4 mutational *** ratios(HRs)from multivariate analyses were pooled in the meta-analysis and various adjustment strategies for confounding factors were *** search was conducted in numerous databases,including MEDLINE(PubMed),Embase,Cumulative Index to Nursing and Allied Health Literature(CINAHL)(EBSCO host),and WHO Global Index Medicus,through March 18th,***-analyses,editorials,letters to the editor,case reports,studies on other primary cancers,studies with primary metastatic sites other than the liver,studies lacking specific oncological outcome variables or genetic data,non-English language studies,and studies omitting residual disease data from liver metastasectomy were *** remaining 47 studies were summarized in a descriptive table which outlines the key characteristics of each study and final results were graphically ***:RAS mutation status was negatively associated with overall survival(OS)(HR,1.68;95%CI,1.54–1.84)and recurrence free survival(RFS)(HR,1.46;95%CI,1.33–1.61).A negative association was also found for BRAF regarding OS(HR,2.64;95%CI,2.15–3.24)and RFS(HR,1.89;95%CI,1.32–2.73)and SMAD4 regarding OS(HR,1.93;95%CI,1.56–2.38)and RFS(HR,1.95;95%CI,1.31–2.91).For PIK3CA only three studies were eligible and no significant associati
