Abstract：Objective To investigate the trends in incidence of malignant tumors in Xiaoshan District, Hangzhou City from 2015 to 2020, so as to provide the evidence for improving the control strategy for malignant tumors. Methods Data on incidence of malignant tumors in Xiaoshan District from 2015 to 2020 were collected through Hangzhou Municipal Chronic Disease Monitoring Management System. The crude incidence, Chinese population-standardized incidence, world population-standardized incidence, cumulative incidence for 0 to 74 years, and truncated age-standardized incidence for 35 to 64 years of malignant tumors were calculated, and the trends in incidence of malignant tumors were analyzed using average annual percent change (AAPC). Results The crude incidence, Chinese population-standardized incidence, world population-standardized incidence, cumulative incidence for 0 to 74 years, and truncated age-standardized incidence for 35 to 64 years of malignant tumors were 476.95/105, 333.30/105, 257.01/105, 28.30% and 425.79/105 in Xiaoshan District from 2015 to 2020, which all appeared a tendency towards a rise (AAPC=4.36%, 3.82%, 3.99%, 3.79% and 5.20%, all P<0.05). The crude incidence, Chinese population-standardized incidence, world population-standardized incidence, cumulative incidence for 0 to 74 years, and truncated age-standardized incidence for 35 to 64 years of malignant tumors were 491.47/105, 313.31/105, 251.51/105, 28.78% and 338.82/105 among men, and both the crude incidence and truncated age-standardized incidence for 35 to 64 years appeared a tendency towards a rise (AAPC=3.00% and 1.73%, both P<0.05), while the crude incidence, Chinese population-standardized incidence, world population-standardized incidence, cumulative incidence for 0 to 74 years, and truncated age-standardized incidence for 35 to 64 years of malignant tumors were 462.98/105, 348.46/105, 262.13/105, 27.74% and 504.91/105 among women, which all appeared a tendency towards a rise (AAPC=5.77%, 5.72%, 5.79%, 5.65% and 7.48%, all P<0.05). The incidence of malignant tumors appeared a tendency towards a rise with age, and the crude incidence of malignant tumors showed a tendency towards a rise among people at ages of 15 to 44 years and 45 to 64 years (AAPC=9.85% and 4.88%, both P<0.05). Lung cancer, thyroid cancer, colorectal cancer, breast cancer and gastric cancer were the five most common cancers, accounting for 59.63% of all malignant tumors, and the incidence of lung cancer, thyroid cancer, colorectal cancer and breast cancer all showed a tendency towards a rise (AAPC=5.90%, 13.01%, 4.60% and 4.47%, all P<0.05). Conclusions The incidence of malignant tumors showed a tendency towards a rise in Xiaoshan District from 2015 to 2020. The rise in the incidence of malignant tumor was higher in females than in males, and malignant tumors tended to develop at a young age. Lung cancer, thyroid cancer, colorectal cancer, breast cancer and gastric cancer are major malignancies that threaten human health in Xiaoshan District.
