Abstract:
Objective To study the effect of age on the recurrence-free survival rate after hepatic resection for hepatocellular carcinoma(HCC)and the relationship between microvessel density (MVD)and recurrence of HCC in the elderly. Methods Severty one cases of elderly patients with HCC were analyzed retrospectively with 352 cases of non-elderly HCC patients as control,and the effect of age on the recurrence-free survival rate was studied.The expressions of CD34 and endocan in HCC tissues were detected by immunohistochemistry in 30 elderly and 30 non-elderly patients.Results The 1-,3- and 5-year recurrence free survival rates were 75.7%,43.0% and 43.0% in the elderly group respectively,which were higher than those in the non-elderly group(53.6%,38.5% and 33.4%,respectively,Log Rank value=10.25,P＜0.05).The positive rate of alpha fetoprotein (AFP)in the elderly group was 47.9%,which was lower than that in the non-elderly group(62.2%)(X2=23.68,P＜0.05).The median survival times in the high CD34-MVD group and high endocan MVD group were shorter than those in the low CD34-MVD group and low endocan-MVD group(260 d vs.850 d,360 d vs.800 d,Log Rank value was 22.18 and 20.56 respectively,both P＜0.05).Conclusions The long-term prognosis of hepatic resection for HCC is better in elderly patients than in non-elderly patients.The recurrence of HCC in the elderly is closely related with angiogenesis.
