1、子宫内膜间质肉瘤有关预后临床病理研究摘要目的:进一步探讨低度恶性子宫内膜间质肉瘤临床病理特征与复发、转移的关系。方法:对20例低度恶性子宫内膜间质肉瘤(LGESS)分别从患者的年龄,肿物体积,浸润子宫肌层深度及浸润血管状况,核分裂计数并做免疫组化:SMA、Desmin、CD10、ER、PR、Ki-67、P53O结果:年龄35〜53岁,平均42岁,肿物体积1.8〜9.5cm3>/sup>,平均4.5cm3>/sup>o肿物与子宫肌壁界不清,树叶样生长方式,切面灰黄质软,瘤细胞一致类似于正常增生期子宫内膜间质,肿瘤血管独特,由类似于正常子宫内膜的螺旋动脉和薄壁血管腔构成,细胞异型性小
2、,核分裂少,免疫组化SMAG)、Desmin(-)、CD10(+)、ER(+)、PR(+)、Ki-67(+<15%).P53(-〜+)。随访20例:其中2年内复发者1例,3〜4年复发者1例,5〜8年复发者3例,8-10年复发者2例,1年半复发又隔3年死亡1例,其余12例10年未见复发转移。结论肿物体积<3.5cm3>/sup>,浸润子宫肌壁较浅者未见复发转移,肿物体积〉3.5cm3>/sup>,浸润子宫肌壁较深尤其有淋巴管,血管浸润者易复发、转移,未切除全子宫及双附件者易复发、转移,提示此类肿瘤应作全子宫及双附件切除。关键词低度恶性子宫内膜间质肉瘤复发转移Abstract0bje
