Abstract: Objective The aim of this study was to study the incidence and mortality of malignant tumors in Shaanxi Cancer Registry in 2016.Methods The incidence and mortality data of malignant tumors in 23 cancer registration areas of Shaanxi province were collected,the crude incidence(mortality),standardized incidence(mortality),and cumulative incidence(mortality)(0~74 years old)of malignant tumors in Shaanxi province were calculated.Results In 2016,the incidence of malignant tumors in the cancer registration area of Shaanxi province was 212.40/100,000,the age-standardized incidence by Chinese standard population was 142.42/100,000 and age-standardized incidence by World Segi's standard population was 152.25/100,000.The incidence of tumors in urban areas(228.50/100,000)was higher than that in rural areas(190.38/100,000),the incidence of male tumors(244.86/100,000)was higher than that of females(178.66/100,000).In 2016,the the age-specific incidence of malignant tumors in Shaanxi cancer registration areas was lower before the age of 35,and the incidence increased rapidly after the age of 35 years old,reached the peak incidence in the 80~84-year-old age group,and then decreased slightly.In 2016,the top five malignant tumors in Shaanxi province were lung cancer,stomach cancer,liver cancer,breast cancer and esophageal cancer.In 2016,the mortality of malignant tumors in the cancer registration area of Shaanxi province was 144.46/100,000,the age-standardized mortality by Chinese standard population was 94.42/100,000 and the age-standardized mortality by World Segi's standard population was 90.05/100,000.The mortality of malignant tumors was low before the age of 40,and gradually rose after the age of 40,reaching a peak in the 80~84-year-old age group,and then slightly decreased thereafter.Lung cancer,liver cancer,stomach cancer,esophageal cancer and colorectal cancer were the top five deaths from malignant tumors in the cancer registration areas of Shaanxi province in 2016.Conclusion Lung cancer,liver cancer,gastric cancer and esophageal cancer are common malignant tumors in Shaanxi province.The prevention and control of malignant tumors in men over 40 years old should be emphasized.
