Objective: To further understand the clinical and pathological features of adolescent colorectal cancer. Methods: The clinical data of 82 adolescent colorectal cancer in 594 cases of colorectal cancer admitted in the past 20 years were retrospectively reviewed and analyzed. Results: The prevalence of colorectal cancer in adolescents was 26 to 30 years old (56.1%). The prevalence was similar in men and women. The distribution of tumors was more common in the rectum and sigmoid colon (79.3%), and the ulcer type was 47.6% Middle-aged and elderly patients; mucinous adenocarcinoma, poorly differentiated adenocarcinoma and mucinous carcinoma accounted for 76.8%.
