Abstract: Objective To analyze the incidence and mortality of cancer in Sichuan cancer registries in 2015,and to provide reference for cancer prevention and control. Methods The data of 2015 were collected from 24 cancer registries in 2018.Incidence/mortality rate were stratified by gender,age group and regions.Crude rate,age-standardized rate[By Chinese(2000)and Segi's population],cumulative rate(0~74 years old)and top 10 leading cancers were calculated. Results In 2015,the incidence rate of cancer was 256.11/100,000(303.60/100,000 in males and 207.19/100,000 in females;267.34/100,000 in urban areas and 250.44/100,000 in rural areas).And the age-standardized rate by Chinese standard population(ASIRC)and by Segi's population(ASIRW)were 169.39/100,000 and 167.96/100,000 respectively.The cumulative rate(0~74 years old)was 19.51%.Lung cancer,liver cancer,esophageal cancer,stomach cancer and colorectal cancer were the most common cancer in Sichuan.The mortality rate of cancer was 175.59/100,000(231.50/100,000 in males and 117.98/100,000 in females;177.88/100,000 in urban areas and 174.43/100,000 in rural areas),the age-standardized rate by Chinese standard population(ASMRC)and by Segi's population(ASMRW)were 112.14/100,000 and 111.73/100,000 respectively,and the cumulative rate(0~74 years old)was 12.62%.Lung cancer,liver cancer,stomach cancer,esophageal cancer and colorectal cancer were the most common causes of cancer death in Sichuan. Conclusion The incidence and mortality of cancers in Sichuan were at the average level in western China and lower than national average.Lung cancer,liver cancer,esophageal cancer,stomach cancer,colorectal cancer and female breast cancer were the most common cancers in Sichuan.Population aged 50 and above were high risk of cancer.Comprehensive prevention and control strategies should be implemented for the most common cancer and among the high risk population.
