Abstract: Objective The aim of this study was to investigate the incidence and mortality of malignant tumors among urban residents in Yingkou City in 2021,and to explore the key points of prevention and treatment of malignant tumors. Methods Based on the cancer registration data of Yingkou urban area in 2021,the incidence,crude mortality,age-standardized incidence by Chinese standard population(ASIRC),age-standardized mortality by Chinese standard population(ASMRC),age-standardized incidence by world standard population(ASIRW),age-standardized mortality by world standard population(ASMRW),and the ranks of incidence and mortality of malignant tumors were calculated and analyzed. Results In 2021,the incidence of malignant tumors among urban areas of Yingkou City was 475.86/100,000,ASIRC was 234.93/100,000 and ASIRW was 224.76/100,000.The top five most cancers by incidence were lung cancer,female breast cancer,colorectal cancer,thyroid cancer and gastric cancer.The crude mortality was 271.99/100,000;ASMRC was 118.42/100,000,and ASMRW was 115.80/100,000.The top five most cancers by mortality were lung cancer,colorectal cancer,liver cancer,breast cancer and pancreatic cancer.Both the incidence(χ2=1,950.616,P＜0.001)and mortality(χ2=2,283.237,P＜0.001)of malignant tumors increased with age,and reached the peak at the age of 80-84(incidence:1,619.35/100,000 and mortality:1,629.11/100,000). Conclusion Lung cancer,female breast cancer,colorectal cancer and thyroid cancer are the key types of cancer that need to be focused on prevention and treatment in urban areas of Yingkou City;The elderly people are at a high-risk group for malignant tumors;Effective tertiary prevention measures should be comprehensively implemented for this high-risk populations to reduce the burden of malignant tumor diseases.
