Abstract:
Objective Based on the cancer registry data to analyze the mortality and survival of liver cancer in China. Methods Liver cancer data of 2011 were retrieved from the National Cancer Registry Database.Liver cancer deaths were estimated using age?specific rate by areas and gender according to the national population in 2011. Mortality data from 22 cancer registries during 2000?2011 were used to analyze the mortality trend, and data from 17 cancer registries during 2003?2005 were used for survival analysis. Results The estimates of liver cancer deaths were about 322 thousand in 2011 with a crude mortality rate of 23.93/105.There was an increasing trend of crude mortality rate of liver cancer during 2000?2011 in 22 Chinese cancer registries with an average annual percentage change of 0.7%(95%CI:0.2%?1.2%), 1.1%in urban and 0. 4% in rural areas. After age standardization with Segi′s population, the mortality rate was significantly decreased, with an APC of -2.3%, -1.9% in urban and -2.2% in rural populations. The 5?year age standardized relative survival was 10.1%(95%CI:9.5% to 10.7%), and the 1?, 3?and the 5?year observed survival rates were 27.2%, 12.7%, and 8.9%, respectively. Conclusion Liver cancer is a major cancer threatening people′s lives and health in China, and the liver cancer burden is still high.
