Abstract: Objective To describe and analyze the incidence and mortality of malignant tumors in Daoli District of Harbin from 2008 to 2012.Methods The tumor registration data of 2008—2012 reported by the Daoli District Cancer Registry was collected.The crude incidence and mortality,China standardization rate,World standardization rate,cumulative rate and truncated incidence rate of major malignant tumors were calculated and trends of the incidence and mortality of malignant tumors in 5 years were analyzed.Results From 2008 to 2012,there were 10 893 cases of malignant tumors in Daoli District of Harbin,including 5879 males and 5 014 females.The incidence rate increased first and then stabilized.Incidence of malignancy,China standardization rate,world standardization rate,cumulative rate and truncated incidence rate in men were higher than those in women.The incidence rates were at a low level in the 0~25 age group,rising rapidly in the 25~80 age group,reaching a peak at the age of 80,and then beginning to decline.From 2008 to 2012,there were 6 801 cases of malignant tumor deaths in Daoli District of Harbin,including 4 069 males and 2 732 females.There was no significant change in mortality over five years.Malignancy mortality,China standardization rate,world standardization rate,cumulative rate and truncated incidence rate in men were higher than those in women.The mortality rates were at a low level in the 0~30 age group,rising rapidly in the 30~75 age group,reaching a peak at the age of 75,and then beginning to decline.The highest incidence of malignant tumors in Daoli District from 2008 to 2012 was lung cancer,followed by liver cancer,colorectal cancer,stomach cancer and breast cancer.The highest mortality rate of malignant tumors was lung cancer,followed by liver cancer,colorectal cancer,stomach cancer and pancreatic cancer.Conclusion The incidence of malignant tumors in Daoli District of Harbin City increased first and then stabilized in 2008-2012,and there was no significant change in mortality.Lung cancer,digestive system malignant tumors,and female breast cancer are the main cancer types of malignant tumors incidence and death in Daoli District of Harbin.
