本文選題：結(jié)直腸腫瘤　切入點：內(nèi)分泌腺腫瘤　出處：《中國臨床醫(yī)學影像雜志》2017年06期

【摘要】：目的:探討結(jié)直腸原發(fā)神經(jīng)內(nèi)分泌癌(NECs)的CT征象,以提高結(jié)直腸原發(fā)NECs的術(shù)前診斷。方法 :回顧性分析經(jīng)病理確診的32例原發(fā)性結(jié)直腸NECs患者和46例結(jié)直腸腺癌患者的CT表現(xiàn),比較兩組患者發(fā)病年齡、性別、腫瘤發(fā)生部位、病變大小、腸壁增厚形式、平掃、增強CT值、腸周浸潤情況、有無腸梗阻及其他器官轉(zhuǎn)移等的差異。結(jié)果:與結(jié)直腸腺癌組比較,結(jié)直腸原發(fā)NECs組患者發(fā)病年齡小(t=3.634,P0.001),兩組在腸壁增厚形式、病灶大小、病灶強化程度等方面差異有統(tǒng)計學意義(P0.05),在性別、病灶發(fā)生部位、有無腸梗阻、有無區(qū)域淋巴結(jié)轉(zhuǎn)移、有遠處轉(zhuǎn)移等方面差異無統(tǒng)計學意義(P0.05)。結(jié)論:結(jié)直腸NECs發(fā)病年齡較輕,其CT表現(xiàn)為息肉/腫塊樣病灶,密度均勻,增強動脈期表現(xiàn)為中度或顯著強化,靜脈期進一步強化時,應(yīng)考慮到結(jié)直腸NECs的可能,并可出現(xiàn)顯著強化的肝臟轉(zhuǎn)移病灶。
[Abstract]:Objective: to investigate the CT features of colorectal primary neuroendocrine carcinoma (NECs) in order to improve the preoperative diagnosis of colorectal primary NECs.Methods: Ct findings of 32 patients with primary colorectal NECs and 46 patients with colorectal adenocarcinoma were retrospectively analyzed. The age, sex, location of tumor, size of lesion, thickening of intestinal wall and plain scan were compared between the two groups.Enhanced CT value, periintestinal infiltration, intestinal obstruction and other organ metastasis were different.Results: compared with the colorectal adenocarcinoma group, the age of colorectal primary NECs patients was 3.634% P 0.001. There were significant differences between the two groups in the form of thickening of intestinal wall, the size of lesions and the degree of enhancement of lesions, and there were significant differences between the two groups in sex and location of lesions.There was no significant difference in intestinal obstruction, regional lymph node metastasis and distant metastasis.Conclusion: Colorectal NECs has a younger onset age, and its CT features are polyp / tumor-like lesions with homogeneous density, moderate or significant enhancement in the enhanced arterial phase, and the possibility of colorectal NECs should be taken into account in the further enhancement of the venous phase.The liver metastases can be enhanced significantly.
