TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['Prognostic factors for colorectal cancer with hepatic metastasis are not well-established. We investigated the factors that predicted survival following surgical resection of hepatic metastases in patients with colorectal cancer.', 'Fifty-three patients underwent resection of hepatic metastases of colorectal cancer between January 2000 and December 2005, with follow-up periods that ranged from 3 to 119 months. In this retrospective study, the effects of sex, age, type of hepatic resection, T stage and N stage of the primary cancer, number and size of metastatic hepatic tumors, synchronicity or metachronicity of the liver metastases, surgical resection margins, and preoperative carcinoembryonic antigen (CEA) levels on 1-year and 3-year survival were analyzed using the Kaplan-Meier method and the log rank test.', 'Median survival was 39.9 months and the 3-year survival rate was 62.2%. Twenty patients died during the follow-up period of 3 to 119 months (mean, 48.8±34.24). In univariate analysis, only the surgical margin of the hepatic metastasis resection correlated significantly with 3-year survival. Sex, age, T stage and N stage of the primary cancer, synchronicity or metachronicity of the metastases, number and size of hepatic metastases, type of hepatic resection and preoperative CEA levels did not predict long-term outcome.'] Does hepatic resection margin predict survival in colorectal cancer with hepatic metastasis?
