报告该院肛肠科１９８４年～１９９４年青年人（≤３０岁）大肠癌４９例。临床症状以便血或粘液便血为主，占８３．６％。病理类型为粘液腺癌、印戒细胞癌占５７．８％。４９例中行根治术２９例，姑息性切除９例，结肠造瘘６例，５例因广泛转移仅行剖腹探查。经７年随访，行姑息性手术１５例及未治５例均于确诊后１～２年内死亡，行根治术２９例中１１例术后生存已５年以上（其中３例达６年以上），另５例术后不足２年，现存活。认为青年人大肠癌恶性程度高、病程短、误诊率高、预后差，宜尽早诊治
Reported that there were 49 cases of colorectal cancer among young people (≤30 years old) in the Department of Anorectal from 1984 to 1994. Clinical symptoms were mainly blood or mucous blood in the stool, accounting for 83.6%. The pathological type of mucinous adenocarcinoma and signet ring cell carcinoma accounted for 57.8%. Of the 49 patients undergoing radical resection, 29 underwent radical resection, 9 underwent palliative resection, and 6 underwent colostomy. 5 patients underwent only laparotomy for widespread metastases. After 7 years of follow-up, 15 cases of palliative surgery and 5 cases of untreated patients all died within 1 to 2 years after diagnosis. Of the 29 patients undergoing radical resection, 11 cases survived for more than 5 years (3 of them reached 6 years or more). The other 5 cases were less than 2 years old and survived. Considered that young people have high degree of malignancy, short course of disease, high rate of misdiagnosis and poor prognosis.
