Abstract:
Objective To evaluate the relationship between fatty liver disease and liver metastases from colorectal cancer.Methods Eight hundred and ninety patients with colorectal cancer,who were submitted to hospital from 1993 to 2002 and had complete clinical data,were retrospectively analyzed.Of 890 patients,127 were diagnosed as fatty liver(FL)by ultrasonography,and the other 763 who were without fatty liver were served as controls(NFL).The clinical data including pathology,liver matastasis or mortality after surgery were analyzed.The survival rate and liver matastasis after surgery were followed up and statistically analyzed.Results The liver metastases was lower in FL group than that in NFL group(7 cases vs 102 cases,P=0.012).The tumor size was smaller in FL group than that in NFL group[(4.15±1.80)crn vs(4.77±2.25)cm,P=0.0016].The Dukes B(247/732,33.74%)and C(232/732,31.83%)patients were more common in NFL group,whereas Dukes A(41/121,33.61 %)and B(40/121,32.77%)were more common in FL group with significant difference(P＜0.05).No significant difference was found in 7-year survival rate between two groups who had been followed up(P=0.3024).Conclusion The lower incidence of liver metastases is found in FL group,which indicate that fatty liver disease may inhibit liver metastases from colorectal cancer by underlying mechanisms.
