Objective To analyze survival rate of liver cancer patients hospitalized between 2002 and 2014 in Tumor Hospital Affiliated to Nantong University and to provide evidences for comprehensive evaluation on liver cancer prognosis.
Methods We extracted data on liver cancer inpatients from Qidong and Haimen region of Jiangsu province and hospitalized between January 1st 2002 and December 31st 2014 from Hospital Information System and adopted active and passive follow-up method to obtain information on survival status till March 31st 2016 for all the inpatients recruited. Survival probability (observed survival, OS) was estimated using life-table method with SPSS 22, and differences in survival rates were analyzed by gender, age, and birthplace with Wilcoxon (Gehan) statistics.
Results Survival information were collected from 475 (97.74%) of all inpatients recruited and the 1-, 3-, 5-, and 10-year OS rate of the inpatients were 35.16%, 17.52%, 11.69%, and 6.34%, respectively; the 1-, 3-, 5-, and 10-year OS rates of the female inpatients (48.96%, 29.39%, 21.94%, and 13.96%) were significantly higher than those of the male inpatients (31.66%, 14.54%, 9.18%, and 3.17%) (P = 0.001). The 5-year OS rate of the inpatients aged 0 – 44, 45 – 54, 55 – 64, 65 – 74, and ≥ 75 years were 10.07%, 12.48%, 8.46%, 19.01%, and 0, respectively, with no significant difference (P > 0.05). The 5-year OS rate was 14.62% and 10.31% for the inpatients from Qidong and Haimen region, with a significant difference (P < 0.001).
Conclusion Among liver cancer inpatients from Qidong and Haimen region of Jiangsu province, the observed survival rate is higher among females than among the males and the rate is higher among those from Qidong region than among those in Haimen region, but the rate does not significantly differ by age groups.
