摘 要:宫颈微偏腺癌(MDA)是一种原发于宫颈的特殊类型腺癌,发病率较低。虽然肿瘤细胞分化很好,但是该种肿瘤患者预后极差。由于缺乏恶性细胞学特征,细胞学检查(TCT)几乎无法做出诊断;且由于活检组织标本较小、腺体形态及结构均类似于正常宫颈腺体,活检病理检查也极易漏诊。近年来多项免疫组化指标的联合应用有助于对MDA做出正确的病理诊断,本文对这些免疫组化指标在宫颈微偏腺癌中的应用进行了归纳总结。

Abstract:Minimal deviationadenocarcinoma of cervixis(MDA)a type of adenocarcinoma of primary origin in the cervix with a low incidence.Although tumor cells differentiate well,the prognosis of this tumor patient is extremely poor.Due to the lack of malignant cytological features,cytology tests(TCT)can hardly make a diagnosis;and because biopsy tissue specimens are small,glandular morphology and structure are similar to normal cervical glands,biopsy pathological examination is also easily missed.In recent years, the combined use of multiple immunohistochemical markers has contributed to the correct pathological diagnosis of MDA.The application of these immunohistochemical markers in cervical minimal deviation adenocarcinoma is summarized in this paper.

宫颈微偏腺癌(minimal deviationadenocarcinoma of cervix,MDA),也称为宫颈恶性腺瘤(adenoma malignum,AM),其发病率低,临床上极为少见,肿瘤细胞分化非常好,缺乏恶性细胞学特征,细胞学(TCT)检查中几乎无法做出诊断。而在宫颈活检时,由于活检组织小,且大部分区域肿瘤分化极好,难以与正常宫颈腺体区别,因此活检HE切片也很难做出正确的诊断。虽然MDA的肿瘤细胞分化很高,但是该种肿瘤患者预后极差。如能找到有利于鉴别诊断的免疫组织化学标记物,则能够提高MDA的早期诊断率,从而指导早期治疗。本文重点讨论一下近年来免疫组化指标在MDA诊断中的应用。
1 HIK1083
HIK1083是一种针对胃幽门黏液腺细胞分泌的黏液成分的单克隆抗体,近年来受到较多关注。研究显示[1,2],90%以上宫颈MDA表达HIK1083,但是在MDA中一些分化较差的腺体通常不表达,普通型宫颈腺癌仅少部分呈微弱表达,正常宫颈腺体则不表达HIK1083。另有文章对269例MDA进行Meta分析,HIK1083阳性率达到92.31%[3]。……
