Prognosis of radical resection of liver metastases from colorectal cancer / 中华普通外科杂志

ABSTRACT

Objective To analyze the clinicopathological factors impacting on the prognosis of colorectal cancer liver metastases and to investigate how to improve patients' survival.Methods The clinical data of 103 patients who received radical resection for liver metastases from colorectal cancer from January 2005 to December 2011 were enrolled.The survival curve was drawn by Kaplan-Meier method,and the survival rates were analyzed by Log-rank test.Factors influencing survival were analyzed by Cox regression model.Results All patients were followed up from 10 to 60 months,The 1-,3-,5-year's survival rates were 90％,49％,39％,respectively.Univariate analysis revealed that number and size of liver metastases,distribution of liver metastases,serum CEA concentration,complications,postoperative chemotherapy were related to prognosis (x2 =24.732,9.461,9.568,25.948,25.370,5.701,P ＜ 0.05).Multivariate analysis identified number of liver metastases,serum CEA concentration,complications were as significant predictors of survival (Wald =7.974,12.051,11.547,P ＜ 0.05).Conclusions Number of liver metastases,serum CEA concentration,complication are important prognostic factors for liver metastases from colorectal cancer.Appropriate expansion of surgical indication,early diagnosis with intensive follow-up is crucial to increase the survival rate after hepatectomy for liver metastasis of coloractal carcinoma.
