Abstract: Objective To analyze morbidity and mortality of malignant tumors in Duanzhou District of Zhaoqing City from 2014 to 2016. Methods The incidence and death data of malignant tumors in Duanzhou District of Zhaoqing City from 2014 to 2016 were collected, and the crude morbidity, crude mortality, age-standardized rate, truncated rate of 35-64 years old, cumulative rate, and the rank of top 10 malignant tumors were calculated. Results From 2014 to 2016, in Duanzhou District of Zhaoqing City, the crude morbidity of malignant tumors was 312.50/10⁵（334.97/10⁵ for males, 289.41/10⁵ for females）,with China and world age-standardized rate of 219.16/10⁵ and 214.30/10⁵,respectively. The truncated morbidity of 35-64 years old was 379.76/10⁵, and the cumulative morbidity of 0-74 years old was 24.31%. The crude mortality of malignant tumors was 165.27/10⁵（208.55/10⁵ for males, 120.79/10⁵ for females）, with China and world age-standardized rate of 100.33/10⁵ and 99.52/10⁵, respectively. The truncated mortality of 35-64 years old was 153.81/10⁵, and the cumulative mortality of 0-74 years old was 11.50%. The top 10 morbidity of malignant tumors were lung cancer, colorectal cancer, liver cancer, female breast cancer, nasopharyngeal carcinoma, cerebroma, gastric cancer, thyroid carcinoma, leukemia and prostate cancer, accounted for 74.31% of all malignant tumor cases. The top 10 mortality of malignant tumors were lung cancer, liver cancer, colorectal cancer, nasopharyngeal carcinoma, gastric cancer, female breast cancer, leukemia, esophageal carcinoma, pancreatic cancer and lymphoma, accounted for 83.06% of all malignant tumor deaths. Conclusion Lung cancer, digestive system cancer, female breast cancer and nasopharyngeal carcinoma are the major malignant tumors which seriously affect the health of residents in Duanzhou District of Zhaoqing City.
