脂肪性肝病与结直肠癌肝转移的关系

目的 研究脂肪性肝病对结直肠癌肝转移的影响.方法 回顾性研究1993年1月至2002年12月共890例临床资料完整的结直肠癌患者,其中127例伴脂肪肝.763例无脂肪肝.分别统计两组患者的一般情况、病理资料、肝转移及术后近期死亡情况等临床资料,同时随访患者术后生存期、术后异时性肝转移并进行统计分析.结果 脂肪肝组肝转移7例,明显少于非脂肪肝组(102例,P=0.012).脂肪肝组肿瘤平均直径[(4.15±1.80)cm]小于非脂肪肝组[(4.77±2.25)cm,P=0.0016].脂肪肝组主要为Dukes A期(41/121,33.9%)和B期(40/121,33.1%)患者,而非脂肪肝组以Dukes B期(247/732,33.7%)和C期(232/732,31.75%)患者为主,差异有统计学意义(P＜O.05).两组获得随访资料的患者术后7年内远期生存率比较差异无统计学意义(P=0.3024).结论 脂肪性肝病患者结直肠癌肝转移率低,脂肪性肝病可能通过某种机制抑制肝脏转移性肿瘤的生长.

The relationship between fatty liver disease and liver metastases from colorectal cancer

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.
