直肠类癌是一种良性肿瘤,但其具有潜在恶性的生物学行为,约15%的患者可能发生远处转移。直肠类癌的治疗以外科手术为主,如何判断其侵袭性是选择手术方式的关键,综合文献分析显示,肿瘤大小、浸润深度和病理学类型等是其主要判断指标。而放疗、化疗在直肠类癌治疗上的作用有限,目前尚无一致结论。 Rectal carcinoid tumor is a benign tumor, but it has potentially malignant biological behavior, about 15% of patients may have distant metastasis. The treatment of rectal carcinoids is mainly based on surgery. How to judge the invasiveness of the tumors is the key to choose the surgical method. Comprehensive literature analysis shows that tumor size, depth of invasion and pathological types are the main indicators. The role of radiotherapy and chemotherapy in the treatment of rectal carcinoid tumors is limited, there is no unanimous conclusion.
