Abstract: Objective The aim of this study was to analyze the incidence and death of malignant tumors in Yunnan cancer registry in 2016. Methods The 2016 data of the incidence,death and population of malignant tumors reported by 24 tumor registries in Yunnan province were collected,reviewed and summarized.The crude rate,age-standardized rate,cumulative rate(0-74 years old)and the composition of the top 10 incidence and death of malignant tumors were calculated.These data were conducted stratified analysis by region(urban/rural),gender and age. Results In 2016,the crude incidence of malignant tumors in the tumor registration area of Yunnan province was 212.97/100,000,age-standardized incidence rates adjusted by Chinese standard population(ASIRC)and by World standard population(ASIRW)were 153.45/100,000 and 149.38/100,000,respectively,and the cumulative rate(0~74 years old)was 16.97%.The incidence in men(227.23/100,000)was higher than that in women(198.27/100,000),and the incidence in urban areas(224.56/100,000)was higher than that in rural areas(202.01/100,000).The top 5 malignant tumors were lung cancer,breast cancer,colorectal cancer,liver cancer and cervix cancer in order.The crude mortality of malignant tumors was 127.26/100,000,age-standardized incidence rates adjusted by Chinese standard population(ASMRC)and by World standard population(ASMRW)were 86.67/100,000 and 85.64/100,000,respectively,and the cumulative rate(0~74 years old)was 9.85%.The male mortality(157.19/100,000)was higher than that of females(96.41/100,000),and the rural standardized mortality(ASMRC for 86.01/100,000 and ASMRW for 84.94/100,000)was not different from that of the city(ASMRC for 87.55/100,000 and ASMRW for 86.63/100,000)in age-standardized mortality.The dead of top 5 malignant tumors was lung cancer,liver cancer,colorectal cancer,stomach cancer and breast cancer. Conclusion The incidence and death of malignant tumors in Yunnan province are at a relatively low level.The comprehensive promotion and further standardization of tumor follow-up registration in the province,and the expansion of early screening and early treatment of key cancers will be the focus of cancer prevention and control in Yunnan province.
