[Population-based survival analysis of primary liver cancer in a high-incidence area-Qidong, China during 1972-1991].
Population-based survival and relative survival of primary liver-cancer (PLC) were analyzed for 11,200 cases in an area with high-incidence, Qidong, Jiangsu Province, during 1972 to 1991. Results showed that observed survival was 2.1% and 2.0% in the first (1972-1981) and the second ten years (1982-1991), respectively, and relative survival 2.2% and 2.3%, respectively. Females had more favorable survival than did males, with five-year survival of 3.5% and 1.7% in the first ten years, respectively, and 2.6% and 1.8% in the second ten years, respectively, but without statistical significance in their difference. No significant difference in age groups was found during 1982 to 1991, with five-year survival of 2.2%, 1.9%, 1.3%, 2.2% and 1.5% for males, and 3.7%, 3.1%, 2.8%, 2.1% and 2.6% for females, and with five-year relative survival of 2.2%, 1.95%, 1.4%, 2.4% and 1.9% for males, and 3.7%, 3.1%, 2.9%, 2.2%, and 3.0% for females, in 0-34, 35-44, 45-54, 55-64 and 65-over age groups, respectively. It indicated that prognosis of PLC was poor in Qidong, and it is urgent to screen for PLC in high risk population, to detect it earlier, to manage it with adequate measures, and to improve its survival.
