Objective To retrospectively analyze the morbidity, mortality, epidemiologic trends and distribution characteristic of top-three malignant tumors in Chengdu from 1990 to 2010, and to be aware of the incidence risk factors, and types and syn-position of main tumors, so as to provide evidence for the policy-making of tumor prevention and control.
Methods ICD-10 coding method was used to categorize diseases and analyze the morbidity and mortality of malignant tumors seen in different ages, genders, areas and types, based on the surveillance data in Chengdu collected since 1990.
Results The morbidity reports of top-three malignant tumors in Chengdu from 1999 to 2010 were lung cancer, liver cancer and colorectal cancer, the same as the mortality reports from 1999 to 2005, But the mortality of gastric cancer exceeded that of colorectal cancer and ranked as the third from 2005 to 2010. The mortality of top-three malignant tumors in male patients was higher than those in female patients. No difference was observed between urban and rural areas. The mortality of main malignant tumors rose along with the age growth.
Conclusion Lung cancer, liver cancer and gastric cancer have become the main malignant tumors threatening Chengdu civilians, and their morbidity and mortality are rising yearly, which suggests that the prevention and control measures such as early diagnosis and treatment should be implemented aiming directly at those main tumors.
