Identification of Regional Epidemiological Characteristics and Key Prognostic Factors of Colorectal Cancer in Xinjiang and Shandong

This is a multicenter, retrospective, cross-sectional observational study aiming to investigate the 5-year overall survival (OS) rate of colorectal cancer (CRC) patients in Xinjiang and Shandong provinces of China. A total of no less than 500 pathologically confirmed CRC patients from 7 medical centers during January 1, 2016 to December 31, 2020 will be enrolled. We will collect and analyze the demographic characteristics, lifestyle, clinical pathological features, treatment patterns and survival prognosis data of patients, explore the regional differences of CRC and its key prognostic factors, and construct a CRC prognostic prediction model. The results will provide theoretical guidance for clinical practice and the formulation of public health policies.
