Abstract
目的: 探讨基于第5版WHO内分泌与神经内分泌肿瘤分类(简称第5版WHO分类)中垂体神经内分泌肿瘤(pituitary neuroendocrine tumors,PitNET)的病理诊断情况,并分析其临床病理学特征。 方法: 回顾性分析906例PitNET的临床及影像学、病理组织学特点及免疫组织化学结果。 结果: 906例PitNET中男性469例,女性437例,中位年龄46岁,其中57.7%(523例)为功能性PitNET,表现为肢端肥大、泌乳或停经等,42.3%(383例)为沉默性PitNET,表现为视力下降、头痛等压迫性症状。影像学显示微腺瘤107例,大腺瘤725例,巨大腺瘤74例。依据第5版WHO分类诊断标准,其中SF-1谱系472例(52.1%),PIT-1谱系222例(24.5%),T-PIT谱系151例(16.7%),无确切谱系60例(6.7%),多发性PitNET 1例(0.1%)。 结论: 第5版WHO分类根据转录因子、激素的表达将PitNET进行了更为科学的分类,能够更好地反映PitNET的临床特征。.
