Abstract: Objective The aim of this study was to understand the epidemic situation of malignant tumors in Tianjin during 2015.Methods According to the stratification by region and gender,the crude incidence,standardization rate,cumulative rate(0~74 years),the incidence and death order and composition of the top 10 malignant tumors in Tianjin were calculated.Results In 2015,the incidence of malignant tumors in Tianjin was 319.17/100,000(314.55/100,000 for males and 323.80/100,000 for females),the bid winning rate was 181.17/100,000,and the world standard trte was 175.15/100,000.The incidence of malignant tumors in urban areas was 383.27/100,000,and in rural areas was 252.50/100,000.The top five cancers were lung cancer,colorectal cancer,breast cancer,thyroid cancer and liver cancer.The city's mortality rate for malignant tumors was 185.73/100,000(214.16/100,000 for males,157.14/100,000 for females),ASRC was 92.22/100,000,and ASRW was 90.78/100,000.The mortality of malignant tumors in urban areas was 229.02/100,000,and that in rural areas was 140.71/100,000.The top five deaths from malignant tumors were lung cancer,liver cancer,colorectal cancer,gastric cancer and pancreatic cancer.Conclusion The incidence of malignant tumors in Tianjin was lower than the national average,but the incidence of malignant tumors in women is higher than the national average.The mortality of malignant tumors is higher in urban areas than in rural areas,and higher in men than in women.
