ABSTRACT
Objective To retrospectively study the relationship between several risk factors such as cirrhosis,Child-Pugh classification,tumor size,portal vein tumor thrombus,intraoperative transfusion,hepatic portal occlusion time and the prognosis of hepatic cellular cancer( HCC ) patients after hepatic resection. Methods The clinical data of 123 patients who received hepatic resection for HCC at Tongji Hospital between 2007 and 2009 were retrospectively analyzed. Log-Rank test and Cox proportional hazard model were used in the univariate and multivariate analyses of risk factors. Results 1,2,3,5 year recurrence and survival rates were 54. 17%,66. 67%,81. 40%,87. 50% and 93. 50%,73. 17%,58. 54%,27. 64%,respectively. The mean recurrence time and survival time were 19. 5 months and 42. 9 months. In univariate analysis,presence of cirrhosis(χ2 =11. 159,P=0. 005),Child-Pugh classification(χ2 =7. 715,P=0. 028),tumor size(≥5cm)(χ2 =11. 483,P=0. 004),presence of portal vein invasion(χ2 =22. 271,P=0. 001)were risk factors affecting HCC recurrence. In multivariate analysis,presence of cirrhosis(χ2 =8. 993,P=0. 003),tumor size (≥5cm)(χ2 =4. 022,P=0. 039),presence of portal vein invasion(χ2 =5. 023,P=0. 027)were inde-pendent risk factors affecting HCC recurrence. In univariate analysis,presence of cirrhosis(χ2 =7. 339,P=0. 025),AFP﹥400 ng/ml(χ2 =5. 431,P=0. 042),Child-Pugh classification(χ2 =13. 389,P=0. 002), tumor size(≥5cm)(χ2 =11. 342,P=0. 003),presence of portal vein invasion(χ2 =52. 167,P﹤0. 001), hepatic portal occlusion(χ2 =5. 801,P=0. 037),intraoperative blood transfusion(χ2 =14. 959,P=0. 001) were risk factors affecting a shorter overall survival. In multivariate analysis,presence of cirrhosis(χ2 =9. 133, P=0. 003),Child-Pugh classification(χ2 =4. 799,P=0. 028),tumor size(≥5 cm)(χ2 =9. 101,P=0. 004),presence of portal vein invasion(χ2 =11. 126,P=0. 001),hepatic portal occlusion(χ2 =3. 985, P=0. 046)were independent prognostic factors affecting shorter overall survival. Conclusion Cirrhosis, Child-Pugh classification,tumor size(≥5 cm),presence of portal vein invasion,and hepatic portal occlusion were independent prognostic factors for HCC patients after hepatic resection.
