| Objective: To analyse cancer incidence and mortality in Sichuan cancer registration areas in 2019 and its trend from 2015 to 2019, in order to provide scientific advice for cancer prevention and control. Methods: Cancer data collected from 121 cancer registries in 2019 were analysed, including incidence/mortality, Chinese population standardisation rate (ASRC), world population standardisation rate (ASRW), cumulative rate, truncation rate and top 10 of incidence/mortality, and the trend of ASIRC, ASMRC, cumulative incidence rate and truncation incidence rate from 2015 to 2019 were analysed. Results: In 2019, the incidence of cancer registration areas in Sichuan Province was 276.99/105(289.83/105 in urban areas and 268.92/105 in rural areas; male (326.15/105), female (225.43/105), the ASIRC and ASIRW were 156.72/105 and 154.11/105, respectively. The cumulative incidence rate (0-74 years old) was 17.87%. The top 5 incidence cancers were lung cancer, liver cancer, colorectal cancer, breast cancer and esophageal cancer. The mortality rate was 185.09/105(243.89/105 for males and 123.42/105 for females; 188.00/105 in urban areas, 183.27/105 in rural areas), the ASMRC was 97.18/105, the ASMRW was 96.83/105, and the cumulative mortality rate (0-74 years old) was 11.16%. The top 5 deaths were lung cancer, liver cancer, esophageal cancer, stomach cancer and colorectal cancer. From 2015 to 2019, the successful incidence of malignant tumor, the cumulative incidence of 0-74 years old, and the truncated incidence and mortality of 35-64 years old showed a decreasing trend, with statistical significance (P < 0.05), and the average annual decrease was 1.93%, 2.25%, 2.56%, 13.51%. Conclusion: The cancer incidence in Sichuan Province is slightly lower than the average level in western China and lower than the whole country. Lung cancer, liver cancer, colorectal cancer, breast cancer and esophageal cancer are the major types of cancer in the province, and people over 50 years old are the groups with a high incidence of cancer, and comprehensive prevention and control should be carried out according to the key major and groups of cancer. |
