Trends in incidence of malignant tumors in Yuyao City from 2011 to 2018 / 预防医学

ABSTRACT

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.
