ObjectiveTo analyze the prevalence trend and survival of liver cancer in Yangpu District， Shanghai， from 2002 to 2016.

MethodsData on liver cancer incidence and mortality from 2002 to 2016 were collected from the Shanghai cancer registry system for the registered population in Yangpu District and the number of the registered population published by the public security department. The standardized liver cancer incidence and mortality rates were calculated using the world standard population to analyze the trends of the liver cancer incidence and mortality， in general， by gender and by age. Life table method was used to calculate the survival rate， and log-rank test was used to analyze the difference of 5-year survival rates and the period of diagnosis between patients with liver cancer by gender.

ResultsThe overall incidence and mortality of liver cancer showed a decreasing trend from 2002 to 2016. After removing the influence of community aging， the standardized annual percentage change （APC） of morbidity and mortality was -3.10% （P<0.01） and -3.44% （P<0.01）， respectively. The morbidity and mortality of males were significantly higher than that of females （P<0.01） by Z test. The incidence of liver cancer started to rise obviously from 40 years old， and the death rate raised obviously from 50 years old. 4 007 liver cancer patients were followed up for 5 years. The 5 years observed survival rate was 12.45%， and the median survival time was 281.48 days. The 5-year survival rate of male liver cancer patients was higher than that of female patients， and there was a significant difference（P<0.01）.46.58% of liver cancer patients were diagnosed in the advanced stage， and only 13.46% was diagnosed at the early-stage. There was no statistical difference in the proportion between men and women at different stages （P=0.11）.

ConclusionThe overall incidence and mortality rates of liver cancer from 2002 to 2016 show a slowly decreasing trend， with higher incidence and mortality rates in men than in women. Middle-aged and elderly people are still the main population of morbidity and death. The five-year survival rate is low， and the diagnostic periods are mostly in the middle and late stages of cancer.
