摘要目的 探讨卵巢Brenner肿瘤临床病理特征和诊断.方法 收集首都医科大学附属北京妇产医院2012年1月至2018年5月47例卵巢Brenner肿瘤,分析其临床资料、影像学检查、组织病理学特征及免疫组织化学表型.结果 患者年龄30~73岁,平均年龄为55岁,其中39例(83.0%)已绝经.Brenner瘤、交界性Brenner瘤及恶性Brenner肿瘤分别为40例(85.1%)、5例(10.6%)、2例(4.3%).常用的肿瘤标志物CA199、CA125在47例卵巢Brenner肿瘤中显示正常或仅轻度升高,术前影像学未提示为卵巢Brenner肿瘤.镜下,Brenner瘤是由形态温和的移行细胞样细胞巢团状分布在纤维瘤样间质内;交界性Brenner瘤为增生的轻度异型的移行细胞样细胞突入囊腔,缺少间质浸润;恶性Brenner肿瘤的肿瘤细胞不同程度核异型,有间质浸润.免疫组织化学表达:所有病例细胞角蛋白(CK)7、GATA3、p63及CK5/6均阳性表达,Ki?67在Brenner瘤增殖指数低于5%,在恶性Brenner肿瘤中达20%~30%,但病例数有限,有待扩大样本量进一步证实.结论 卵巢Brenner肿瘤多发生于绝经后妇女,以Brenner瘤最常见,影像学及肿瘤标志物检查对卵巢Brenner肿瘤无诊断价值,其诊断及分类仍然依赖于组织病理学.

abstractsObjective To investigate the clinicopathological characteristics and diagnosis of ovarian Brenner tumors. Methods Forty?seven cases of ovarian Brenner tumors were enrolled from January 2012 to May 2018 at Beijing Obstetrics and Gynecology Hospital, Capital Medical University. Clinical data, imaging examination, histopathological characteristics and immunohistochemical phenotype were analyzed. Results The age of the patients ranged from 30-73 years and the mean age was 55 years. Thirty?nine patients (83.0%) were postmenopausal. Forty cases (85.1%) of the Brenner tumors were benign, five (10.6%) borderline and two (4.3%) malignant. Usual tumor markers of ovarian carcinoma, including CA199 and CA125 were normal or mild elevated in the 47 cases. Imaging before surgery was not specific to Brenner tumors. Microscopically, benign Brenner tumors were composed of nests of bland, transitional?type cells within a fibromatous stroma. In our 5 cases of borderline Brenner tumors, mildly atypical transitional?type cells were projected into the cyst lumens and lack of stromal invasion. In 2 cases of malignant Brenner tumors, different degrees of nuclear atypial transitional?type cells exhibited stromal invasion. Immunohistochemical stains for CK7, GATA3, p63 and CK5/6 were positive in all cases. Ki?67 was less than 5% in Brenner tumors, and up to 20%-30% in malignant Brenner tumors. Conclusion Brenner tumors are mostly seen in postmenopausal patients and are usually benign. Imaging examination and usual ovarian tumor markers do not provide diagnostic value. Diagnosis and classification of Brenner tumors depend on histopathological evaluation.
