Objective: To investigate the trends in incidence of malignant tumors in Yuyao City, Zhejiang Province from 2011 to 2018, so as to provide insights into formulation of the malignant tumor control strategy. Methods: Data pertaining to the incidence of malignant tumor in Yuyao City from 2011 to 2018 were captured from the Chronic Disease Surveillance Module of Ningbo Municipal Digital Disease Control and Prevention Platform. The crude incidence, Chinese population-standardized incidence, global population-standardized incidence, cumulative incidence (0 to 74 years of age), and truncated age-standardized incidence (35 to 64 years of age) of malignant tumors were estimated, and the trends in incidence of malignant tumors were analyzed in Yuyao City from 2011 to 2018 using average annual percentage change (AAPC). Results: The crude incidence, Chinese population-standardized incidence, global population-standardized incidence, cumulative incidence (0 to 74 years of age), and truncated age-standardized incidence (35 to 64 years of age) of malignant tumors were 433.78/105, 289.37/105, 224.22/105, 25.83% and 83.34/105 in Yuyao City from 2011 to 2018, with AAPC of 5.90%, 3.31%, 3.31%, 2.84% and 4.24%, respectively (all P<0.05), and the incidence of malignant tumors appeared an overall tendency towards a rise. The incidence of malignant tumors increased with age in Yuyao City from 2011 to 2018, and the incidence of malignant tumors was significantly higher in women than in men at ages of 20 to 54 years, while higher incidence was seen in men than in women at ages of 55 years and older. The ten most common malignant tumors included lung cancer, gastric cancer, colorectal cancer, liver cancer, breast cancer, esophageal cancer, thyroid cancer, pancreatic cancer, prostate cancer and cervical cancer, accounting for 78.84% of all malignancies, and the the incidence of lung cancer, colorectal cancer, breast cancer, thyroid cancer, pancreatic cancer and prostate cancer appeared a tendency towards a rise year by year, with AAPC of 8.37%, 5.36%, 6.42%, 24.81%, 5.49% and 18.78%, respectively (all P<0.05). Conclusions The of malignant tumors appeared a tendency towards a rise in Yuyao City from 2011 to 2018, and lung cancer, thyroid cancer, specific female cancers, male gastrointestinal and prostate cancers should be given a high priority for cancer control in Yuyao City in the future. Early screening and early diagnosis of cancers should be facilitated among high-risk populations.

ObjectiveTo analyze the morbidity and mortality characteristics and prevalence trends of asopharyngeal carcinoma among registered residents in Yuyao City of Zhejiang Province from 2012 to 2021， and to provide suggestions for the prevention and treatment of the cancer. MethodsThe incidence and mortality data of asopharyngeal carcinoma in Yuyao City from 2012 to 2021 were collected. The incidence， mortality， standardized rate， cut-off rate， cumulative rate and annual percentage of trend change were calculated. A linear logarithmic model was used to analyze the variation trend. ResultsFrom 2012 to 2021， the crude incidence rate was 6.46/10⁵ in Yuyao， while the Chinese standard rate was 4.78/10⁵ and the world standard rate was 3.68/10⁵， which all increased over the years. The indicators in males were higher than these in females （χ²=85.377， P<0.01）. The cumulative incidence rate of ≥65 years old group was the highest （13.63/10⁵）. The crude mortality rate was 2.45/10⁵， while the Chinese standardized rate was 1.47/10⁵ and the world standard rate was 1.14/10⁵. The crude mortality rate in males was 3.25/10⁵，which was higher than females（1.68/10⁵）（χ²=20.958， P<0.01）. Overall， the cumulative rate was highest reached its peak in ≥75 years old group （10.75/10⁵）. The male mortality rate reached its peak in the ≥80-year-old population （12.36/10⁵）， and the female mortality rate in ≥75 years old group （11.03/10⁵）. ConclusionThe incidence rate of asopharyngeal carcinoma in Yuyao City is generally increasing， but the mortality rate has no obvious variation. The key population for prevention and treatment in Yuyao City is male， middle-aged and elderly.
