神经内分泌肿瘤(neuroendocrine neoplasm,NEN)是一组起源于肽能神经元和神经内分泌细胞的异质性肿瘤。2010年第4版《世界卫生组织(World Health Organization,WHO)消化系统肿瘤分类》对NEN的命名、分类和分级进行修订和统一,纠正以往NEN诊断名称使用的混乱、规范NEN的病理分类和分级,增加NEN诊断的互认性,为NEN的临床治疗、预后判断提供必要的病理学信息。病理医师在常规病理诊断报告时应当按照一定的步骤要求,结合免疫组织化学染色结果进行准确的诊断、分类和分级,并提供临床分期必需的病理参数。近年来,有关NEN的临床和基础研究结果,使学者们对2010年第四版《WHO消化系统肿瘤分类》的部分内容和分级标准有了新的认识,提出了新观点,一些数据有待于进一步的大样本探讨证实。
Abstract
Neuroendocrine neoplasm (NEN)is a group of heterogeneous tumors originated from the peptidergic neurons and neuroendocrine cells. A revised system of classification
nomenclature and grading of NEN was proposed by the fourth edition of “World Health Organization classification of tumours of the digestive system”in 2010. It apparently contributes to unify the method of classification
put an end of the confusion in nomenclature
standardize the grading system and predict the outcomes more accurately. With the combination of the results by immunohistochemical studies
pathologists should be in accordance with the requirements to make a diagnosis of NEN with accurate classification
grading and the pathological parameters essential to staging. Recently
new advances in NEN study put forward a new view in the classification and grading system that will lead to the updates of the diagnostic system after further studies on a large scale of samples.
