非上皮源性卵巢肿瘤性类固醇激素受体的研究

采用Lee SH荧光组化法检测42例非上皮性卵巢肿瘤的雌激素受体(ER)和孕激素受体(PR)。结果显示:2/4例卵胞膜细胞瘸有ER、PR;6/8例颗粒细胞瘤有ER、PR,其中4倒受体水平较高;12/16例畸胎瘤有ER、PR,畸胎瘤中含柱状上皮、皮脂腺、汗腺、软骨时,显示较高的ER、PR水平。内胚窦瘤、无性细胞瘤及纤维瘤均显示受体阴性。1/4例胃肠道转移癌有ER、PR阳性细胞。结果提示,应重视颗粒细胞瘤ER、PR的检测,对受体阳性的肿瘤患者,也许可进行激素治疗。

ESTROGEN AND PROGESTERONE RECEPTOR IN NONEPITHELIOGENIC OVARIAN TUMORS

Tissue samples from 42 patients with nonepitheliogenie ovarian tumors were assayed for estrogen receptor (ER) and progesterone receptor (PR) by Lce's fluorescent histochemical method. 2 of 4 theca cell tumor, 6 of 8 granulosa cell tumor had ER and PR. Among the 6 cases of granulosa cell tumor, 4 cases exhibited a high level of receptors (ER、PR positsve cell: 40%～50% of total tumor cells). As to teratomas, the epithelial cells of sweat glands, and cylindrical epithelia, as well as chondrocytes were ER PR positive. No ER-and PR-positive cells were found in endodermal sinus tumors, drsgerminomas and fibromas. Of 4 mataststic ovarian tumors, which were from gastrointestinal adenocarcinoma, tbe ER-and PR-positive cells were found in 1 specimen. The findings suggested that hormone-related therapy might be worthy of trying on thc patients with receptor positive granulosa cell tumor.
