Abstract: Objective The aim of this study was to collect diagnosis,treatment,and follow-up information of inpatients with malignant tumors at the Affiliated Tumor Hospital of Xinjiang Medical University,analyze the distribution and composition of malignant tumor types,mortality,and survival status,and provide reference for the prevention and treatment of malignant tumors in the local area. Methods The case and mortality data of inpatients with malignant tumor from 2010 to 2020 were calculated,and the survival status was collected by follow-up.The composition,different pathological stage,composition and sequential changes of malignant tumors,as well as survival rates of the 1-year,3-year and 5-year were analyzed. Results A total of 111,418 patients with malignant tumor were admitted to the hospital from 2010 to 2020.Breast cancer accounted for 20.67% of inpatients,followed by lung cancer,thyroid cancer,cervical cancer and gastric cancer; The leading cause of malignant tumor death was lung cancer(accounting for 26.70%),followed by gastric cancer,esophageal cancer,liver cancer and colorectal cancer.The 1-year,3-year,and 5-year survival rates were 87.20%,65.80% and 57.20%,respectively.The overall survival rates of patients with stages Ⅰ and Ⅱ malignant tumors were significantly higher than those of patients with stages Ⅲ and Ⅳ(P=0.003). Conclusion Breast cancer,lung cancer,thyroid cancer,cervical cancer and gastric cancer are the high incidence of malignant tumors in Xinjiang,among which thyroid cancer,breast cancer,and cervical cancer have a higher 5-year survival rate.Early screening,diagnosis and treatment of malignant tumors should be strengthened,and prevention strategies and resource allocation should be adjusted in time according to the distribution of malignant tumors to reduce the incidence and mortality of malignant tumor and improve the health level of people in Xinjiang.
