Abstract: ObjectiveTo analyze the risk factors for interval time Pattern of hepatic metastases from rectal cancer after radical surgery and provide supportive evidence for predicting and preventing hepatic metastasis from rectal cancer after radical surgery. Methods A retrospective study of 143 patients with hepatic metastasis from rectal cancer after radical surgery from 1995 to 2010.The data was analyzed to evaluate significant risk factors for interval time.Pattern of hepatic metastasis from rectal cancer after radical surgery. Results The histologic differentiation,Dukes criteria and extrahepatic metastasis were independently correlated with the interval time of hepatic metastasis,while the depth of invasion was independently correlated with the pattern of hepatic metastasis. Conclusion We could evaluate the interval time of hepatic metastasis with the histologic differentiation,Dukes criteria and extrahepatic metastasis,while the depth of invasion could be used to evaluate the pattern of hepatic metastasis from rectal cancer in patients with radical surgery.
