Survival Analysis on a Follow-up Data of Patients with Primary Liver Cancer in Xuhui District of Shanghai / 中国慢性病预防与控制

ABSTRACT

Objective To investigate.the survival rates in a follow-up group of patient with primary liver cancer.Methods The follow-up data of new primary liver cancer cases between year 2001-2004 in Xuhui district was investigated.The age distribution of patients was described.Survival rate was analyzed with single and multiple Cox proportional hazards regression model,respectively.Results The age proportion distribution of patients showed double apexes with one in age 45～50 and another in age 70～75.The arithmetic mean of survival month was 16.4 with 95%CI 14.8～18.1 and median month was 6.9.It was no significance between male and female.Patients who had liver operation owned longer survival time,RR=0.315 5(95%CI 0.243 2～ 0.4093).The sutdy showed 5-year survival rate was 40.90%and 3.95%for patients with or without operation,respectively.It had no significant effect on survival time by gender,age and family history.Conclusion The screening test and intervention in high-risk people shall be done preferentially before peak age,so as to find primary liver cancer earlier,and the more patients can accept a suitable surgery care,the more they can obtain longer survival time.
