ObjectiveTo analyze the characteristics and epidemic trend of malignant tumor in Yueqing City of Zhejiang Province from 2012 to 2015 so as to provide scientific bases for policy making regarding control and prevention of malignant tumor.
MethodsDescriptive epidemiological analyses were made on the data of malignant tumor in Yueqing City from 2012 to 2015.
ResultsThe average annual incidence rate of malignant tumor from 2012 to 2015 was 248.85/105, the incidence rates from 2012 to 2015 were 238.24/105, 242.95/105, 247.15/105, 266.85/105, respectively. The average male incidence rate was 265.82/105, the average female incidence rate was 230.38/105.The former was higher than the latter. The group of 40-year-old and above age accounted for 91.64% of the total number of malignant tumor cases. Leukemia was common among 20-year-old and below age group. Breast cancer, liver cancer and lung cancer were common among 20- to 39-year-old age group. Lung cancer, liver cancer and gastric cancer were common among the age group of 40-year-old and above. The top five incidence rates of malignant tumor were lung cancer, liver cancer, gastric cancer, colorectal cancer and breast cancer, accounting for 56.74% of total cases thereof.
ConclusionFrom 2012 to 2015, the incidence trend of malignant tumor in Yueqing City remained basically stable; the incidence rate remained relatively high and showed a slow rising trend on a yearly basis with the incidence rate of lung cancer increasing most significantly. The male incidence rate of malignant tumor was obviously higher than the female incident rate thereof. For the age group over 40, the incidence rate of malignant tumor increased significantly. It is necessary to pertinently strengthen the relevant health education of malignant tumor and implement the relevant early monitoring, thereby reducing the incidence rate.
