Steroid-converting enzymes in human ovarian carcinomas.

Anti-estrogen therapies for treating ovarian carcinoma have had mixed outcomes suggesting some tumors may be estrogen-dependent. We assayed the activity levels of 17beta-hydroxysteroid dehydrogenase (17beta-HSD), 3beta-hydroxysteroid dehydrogenase (3beta-HSD), 3alpha-hydroxysteroid dehydrogenase (3alpha-HSD/3-KSR) and estrone sulfatase in a series of ovarian epithelial carcinomas. 17beta-HSD activity ratios with estradiol (E(2)) and testosterone (T), and inhibition by isoform-specific inhibitors were used to estimate the contributions of 17beta-HSD isoforms.

Adenocarcinoma of the urinary bladder presenting as locally advanced endometrial carcinoma. Case report and review of the literature.

Background: Carcinoma of the urinary bladder that occurs after urinary diversion is a rare entity. We report a case of an adenocarcinoma arising in a defunctionalized bladder that presented as locally advanced endometrial carcinoma.

Case: A 77-year-old presented with postmenopausal bleeding and mucous vaginal discharge.

Treatment and recurrence patterns in endometrial stromal sarcomas and the relation to c-kit expression.

Introduction: Endometrial stromal sarcomas (ESS) are a rare gynecologic malignancy. The optimal management of this cancer remains unclear, although previous reports have failed to demonstrate a clear benefit to adjuvant chemotherapy or radiation. With the successful application of directed biological therapy in other sarcomas, a review of the behavior and biology of this disease is warranted.

Hysteroscopy and cytology in endometrial cancer.

Objective: To estimate the effect of preoperative diagnostic hysteroscopy on peritoneal cytology in patients with endometrial cancer.

Methods: A total of 256 charts were reviewed. Two cohorts were established based on diagnosis by hysteroscopy or blind endometrial sampling via either endometrial biopsy or dilatation and curettage (D&C).
