青少年大肠癌并非罕见，1987～1996年我院收治的521例大肠癌中，青少年（7～30岁）占52例（10％），其中结肠癌22例，直肠癌30例。临床表现以大便习惯改变、腹痛、便血为主，结肠癌病人腹部肿块也较常见。病理特点是恶性程度高者较多。在52例中，低分化腺癌、粘液腺癌、印戒细胞癌占55％。青少年大肠癌误诊率较高，结肠癌误诊率为82％，直肠癌误诊率77％。本组误诊率78．3％，根治性切除率69．2％。作者认为青少年大肠癌的治疗最有效的方法是根治性切除术。
Adolescent colorectal cancer is not uncommon. Among 521 cases of colorectal cancer admitted to our hospital from 1987 to 1996, 52 (10%) were adolescents (7 to 30 years old), including 22 cases of colon cancer and 30 cases of rectal cancer. Clinical manifestations to change the stool habits, abdominal pain, blood in the stool, abdomen colon cancer patients are more common. Pathological features are more highly malignant. In 52 cases, poorly differentiated adenocarcinoma, mucinous adenocarcinoma, signet-ring cell carcinoma accounted for 55%. Misdiagnosis rate of adolescent colorectal cancer is higher, misdiagnosis rate of colon cancer is 82%, misdiagnosis rate of rectal cancer is 77%. The misdiagnosis rate of 78.3%, radical resection rate of 69.2%. The author believes that the most effective treatment for adolescent colorectal cancer is a radical resection.
