目的

探讨结直肠神经内分泌肿瘤的临床特征、诊治方法及预后。

方法

回顾分析湖北省肿瘤医院自2006年1月至2015年1月收治的25例结直肠神经内分泌肿瘤患者的临床资料。

结果

肿瘤部位:阑尾3例,升结肠3例,乙状结肠2例,直肠17例。分级情况:NET(G1)11例,NET(G2)3例,NEC(G3)8例,MANEC 3例。免疫组织化学:Syn、CgA、NSE阳性表达率为96%,68%和92%。预后:结直肠神经内分泌肿瘤出现转移部位最多见为肝脏。9例Ⅰ期患者生存时间均长于5年。6例Ⅱ期患者,3年内死亡1例,5年内死亡3例,余1例仍在随访中。8例Ⅲ期患者,1年生存率75%,3年生存率50%,5年生存率25%。2例Ⅳ期患者,1例存活28月,另1例存活37月。

结论

结直肠神经内分泌肿瘤缺乏特征性临床表现,主要通过内镜下活组织病理检查明确诊断。结直肠神经内分泌肿瘤治疗方法主要依靠手术治疗,早期预后良好,预后与分期和分级密切相关。

Objective

To investigate the diagnosis, therapy and prognosis of colorectal neuroendocrine neoplasm (NEN) through a retrospective analysis on the colorectal NEN clinical features.

Methods

Clinicopathological data of 25 patients with colorectal NEN from January 2006 to January 2015 in Hubei Cancer Hospital were analyzed.

Results

Three of the 25 cases of NEN occurred in appendix, 3 in ascending colon, 2 in sigmoid colon, 17 in rectum. The NEN were divided into four grades: G1 (11 cases), G2 (3 cases), NEC (8 cases), MANEC (3 cases). Immunohistochemical staining revealed that the positive rates of Syn, CgA and NSE were 96%, 68% and 92% respectively. Liver is the most common place of metastasis in NEN patients. The 5-year survival rate of stage Ⅰ and Ⅲ patients were 100% and 25% respectively, while the 5-year survival rate of stage Ⅱ patients was 50%. The survival time of 2 stage Ⅳ patients was 28 months and 37 months respectively.

Conclusions

The clinical manifestations of colorectal NEN are of non-special and endoscopic biopsy is the major diagnostic modality. The main method of treatment for colorectal NEN is surgery, and the prognosis was associated with clinical stages and grades.
