【摘要】 目的探讨胃肠道神经内分泌肿瘤的CT表现与病理分类关系。方法回顾性分析54例胃肠道神经内分泌肿瘤患者的CT资料,分析其影像特点并与病理进行对照。结果 22例患者为高分化神经内分泌肿瘤,32例为低分化神经内分泌肿瘤。肿瘤直径(>3cm)、肿瘤经壁侵犯、坏死囊变、邻近组织侵犯、淋巴结转移高分化神经内分泌肿瘤、低分化神经内分泌肿瘤两组间差异有显著性(P<0.05)。肿瘤边界、生长方式、增强程度、远处转移在两组间差异无显著性(P>0.05)。结论 CT有助于神经内分泌肿瘤病理分级。更多还原

【Abstract】 Objective To study correlation between the CT features and pathologic classification of gastrointestinal neuroendocrine neoplasms( GE-NENs). Method CT imagings of 54 GE-NENs patients confirmed by histopathology were retrospectively analyzed. Correlation of these imagings findings with pathologic classification was studied.Result Fifty-four cases of GE-NENs included 22 cases of neuroendocrine tumors( NETs) and 32 cases of neuroendocrine carcinomas( NECs). The CT features were significant difference between the two groups including lager tumor size,transmural invasion,areas of cystic changes or necrosis,adjacent organ invasion and lymphadenopathy( P<0. 05). There was no difference between the two types of GE-NENs including tumor boundary,grown pattern,degree of enhancement and distant organ metastasis( P > 0. 05). Conclusion CT can be useful for the pathologic classification of GE-NENs.更多还原
