我院外科１９８５年１月至１９９５年１２月共收治３０岁以下直肠癌２８例，占同期收治直肠癌的９．４６％。其中男女比例为１∶１．１５，平均病程８．４个月，超过６个月的５０％；误诊率为９２．８％；改良Ｄｕｋｅ′ｓ分期Ｃ＋Ｄ期病例占７１．５％；低分化腺癌、粘液癌、未分化癌占７８．５％。１、３、５年生存率为４４％、２８．６％、１６．５％。通过分析表明：青年人直肠癌具有病程长、易误诊、病期晚、恶性程度高、预后差等特点。早期确诊的最有效手段是直肠指诊。手术是首选治疗方法，但保肛手术的选择应慎重，我们建议远切距以５ｃｍ为宜。综合治疗可以改善青年直肠癌病人的预后。
In our hospital from January 1985 to December 1995, 28 cases of rectal cancer under the age of 30 were treated, accounting for 9.46% of rectal cancers during the same period. The ratio of males and females was 1:1.15, the average course of illness was 8.4 months, and 50% was more than 6 months; the rate of misdiagnosis was 92.8%; improved Duke’s stage C+D was 71.5%; poorly differentiated. Adenocarcinoma, mucinous carcinoma, and undifferentiated carcinoma accounted for 78.5%. The 1-, 3-, and 5-year survival rates were 44%, 28.6%, and 16.5%. The analysis shows that young people have the characteristics of long-term rectal cancer, misdiagnosis, late stage, high degree of malignancy, and poor prognosis. The most effective means of early diagnosis is digital rectal examination. Surgery is the preferred treatment, but the choice of sphincter preservation surgery should be careful, we recommend that the distance from the distal cut to 5cm is appropriate. Comprehensive treatment can improve the prognosis of young patients with rectal cancer.
