Abstract: Objective The aim of this study was to analyze the incidence and mortality of malignant tumors in the urban areas of Nantong City in 2020,and the changing trends from 2011 to 2020. Methods The tumor registration data of Nantong urban cancer registry from 2011 to 2020 were used to calculate the incidence,mortality and age-standardized incidence by Chinese standard population(ASIRC),age-standardized mortality by Chinese standard population(ASMRC),age-standardized incidence by world standard population(ASIRW)and age-standardized mortality by world standard population(ASMRW)of malignant tumors in Nantong urban areas by gender,age,and cancer type in 2020.Joinpoint 4.7.0.0 software was used to calculate the average annual percentage change(AAPC)of the incidence,mortality,ASIRC and ASMRC of malignant tumors in the Nantong urban areas from 2011 to 2020,and to analyze the changing trends of the incidence and mortality of all malignant tumors. Results In 2020,9,324 new cases of malignant tumors(5,038 males and 4,286 females)were reported in the Nantong urban areas,with an incidence of 432.63/100,000,ASIRC of 188.82/100,000,and ASMRC of 182.05/100,000.The incidence of top five cancer types in the Nantong urban areas was lung cancer,colorectal cancer,gastric cancer,liver cancer,and female breast cancer,accounting for 56.75% of all cases.A total of 5,442 deaths from malignant tumors(3,371 males and 2,071 females)were reported in the Nantong urban areas,with a crude mortality of 252.51/100,000,ASMRC of 86.00/100,000,and ASMRW of 84.94/100,000.The mortality of top five cancer types in the Nantong urban areas was lung cancer,gastric cancer,liver cancer,colorectal cancer,and esophageal cancer,accounting for 63.93% of all deaths.From 2011 to 2020,the age-standardized incidence and age-standardized mortality of malignant tumors in the Nantong urban areas showed a downward trend,with an average annual decrease of 1.42%(95% CI:-2.69%-0.13%,P＜0.05)and 3.84%(95% CI:-6.07%-1.56%,P＜0.05),respectively. Conclusion Although the incidence and mortality of malignant tumors in the Nantong urban areas are at a high level,the age-standardized incidence and age-standardized mortality are at a low level and are on a downward trend.We should focus on the prevention and control of lung cancer,digestive tract cancer,and female breast cancer,and take different prevention and control measures for different types of cancer to reduce the burden of cancer.
