Prognosis in different sites of CRC. CRC can be divided into right-sided CRC and left-sided CRC according to the pathogenic site. Right-sided CRC includes cancers located in the cecum, ascending colon, and transverse colon, and left-sided CRC includes those located in the descending colon, sigmoid colon, and rectum. The clinical data from the SEER database was used to analyze the prognosis in different sites of CRC. a, b The CRC specific survival rate and overall survival rate varied among the different sites, respectively. c, d The CRC specific survival rate and overall survival rate between the right-sided CRC and left-sided CRC, respectively. e A nomogram model to be used for predicting the prognosis of CRC via some prognostic factors, including adequate node examination, stages, gender, age, and sites
