title: Estrogen and progesterone receptor assay in carcinoma of the cervix with monoclonal antibodies.
abstract: The normal cervix has been shown to contain estrogen and progesterone receptors (ER and PR), but there have been controversial reports on the presence of these receptors in cervical carcinoma. Thus to explore the relationships between the steroid receptor status and cervical carcinoma, tissues of 34 patients with invasive cervical carcinoma prior to treatment and 30 cases of control who underwent hysterectomy due to benign gynecologic diseases at Yonsei Medical Center were analyzed for ER and PR using immunocytochemical assay with monoclonal antibodies and the results were compared with those of conventional steroid binding assay. ER and PR were positive in 65 and 71% of all tumors, respectively, and 59% of the cases were positive for both receptors simultaneously. No significant difference in receptor levels was noted when stratified according to menopausal status or clinical stage. With regard to tumor size, lesions greater than 3 cm had significantly lower receptor positivity when compared with the control. For the histological cell types, a statistically significant higher mean ER level was noted in adenocarcinoma compared to squamous cells. Even though the potential therapeutic significance of these findings is not yet known, they are consistent with the concept that steroid receptors can be used as a guide to endocrine therapy with respect to other prognostic parameters. However, the small number of advanced-stage carcinomas and the absence of data regarding survival rate in this study preclude any definite conclusions.
