Abstract: Objective To probe the curative effect of surgical treatment on colorectal cancer with liver metastasis,the factors that affect postoperative survival rate,and the measures for improving long-term curative effect.Methods Clinical data from 48 cases of colorectal cancer with liver metastasis were analyzed retrospectively,among which 35 cases were treated with radical excision and 13 cases were with non-radical excision.Results 1-,3-and 5-year postoperative survival rates were 91.7%,50.0% and 29.2% respectively.The number of tumor,operation method and postoperative therapy were the important factors for influencing long-term curative effect.Conclusions Early detection and early excision of the metastatic liver cancer is the key to improve healing rate.Comprehensive therapy after operation can improve the long-term curative effect of colorectal cancer with liver metastasis.
