Objective The objective of this study was to analyze the incidence and mortality of malignant tumors in Fuqing city in 2019,as well as and the trend changes from 2015 to 2019.Methods The data of tumor registration in Fuqing city in 2019 were collected and organized.The crude incidence and mortality of tumor,China age-standardized rates,world standard rates and cu-mulative rate(0-74 years old),age-specific rate,and the top 10 malignant tumor incidence and mortality order were calculated.The China age-standardized rate and World age-standardized rate were calculated based on the Chinese standard population from the 2000 National Population Census(ASRC)and Segi′s World standard population(ASRW),respectively.The Joinpoint software was used to calculate the annual percentage change(APC)of incidence/mortality from 2015 to 2019.Results In 2019,the crude incidence of new malignant tumors in Fuqing city was 343.76/100,000(346.30/100,000 for male and 341.06/100,000 for females),ASRC rate was 255.78/100,000,ASRW rate was 244.91/100,000,and the cumulative rate(0-74 years old)was 27.75%.In 2019,the crude mortality of malignant tumors in Fuqing city was 163.63/100,000(212.26/100,000 for male and 111.95/100,000 for female),AS-RC rate was 110.82/100,000,ASRW rate was 107.82/100,000,and the cumulative rate(0-74 years old)was 12.07%.The top 10 incidence of cancers were lung cancer,thyroid cancer,female breast cancer,liver cancer,stomach cancer,colorectum cancer,cervix cancer,esophagus cancer,prostate cancer and brain tumors,accounting for about 80.96%of all cancers.The top 10 mortality of canc-ers were lung cancer,liver cancer,stomach cancer,esophageal cancer,colorectal cancer,female breast cancer,prostate cancer,brain tumors,pancreas cancer and cervix cancer,accounting for about 81.03%of all cancer deaths.From 2015 to 2019,the overall inci-dence of malignant tumors in Fuqing city showed a fluctuating upward trend(APC=1.41%,P>0.05),and the overall mortality showed a slight downward trend(APC=-0.8%,P>0.05),but the changing trends were not statistically significant.Conclusion The overall incidence and mortality of malignant tumors in Fuqing city are at a high level.Lung cancer,thyroid cancer and digestive system malignant tumors are the key malignant tumors endangering the health of residents in Fuqing city,and monitoring and prevention should be strengthened.
