Antioxidative activity of indenestrol A, a diethylstilbestrol metabolite.

To elucidate the various activities of synthetic estrogens, the antioxidative activities of diethylstilbestrol (DES) and related metabolic analogs were examined. The antioxidative activities were assessed in terms of the inhibitory effect on Fe2+(-) and ascorbic acid-induced peroxidation of egg phosphatidylcholine (egg PC), and also superoxide scavenging ability using cyclic voltammetry. Moreover, after in vivo administration of the test compounds to mice, the animals were subjected to hyperoxia, and catalase, glutathione peroxidase and superoxide dismutase activities in the brain, lungs and liver were measured. The results indicated that indenestrol A, one of the metabolites of DES, had the strongest antioxidative activity among the test compounds under both in vivo and in vitro conditions.

Conservative surgery plus adjuvant therapy for vulvovaginal rhabdomyosarcoma, diethylstilbestrol clear cell adenocarcinoma of the vagina, and unilateral germ cell tumors of the ovary.

Significant progress has been made in the 1980s in early-stage vulvovaginal rhabdomyosarcoma, diethylstilbestrol (DES) clear cell adenocarcinoma of the vagina, and unilateral germ cell tumors of the ovary. In an early state of vulvovaginal rhabdomyosarcoma, systemic vincristine, dactinomycin, and cyclophosphamide (VAC) chemotherapy followed by local excision or local radiation results in a high cure rate with retention of future fertility. Similarly, early-stage DES-related adenocarcinoma of the vagina treated by wide local excision and localized vaginal radiation also results in retention of fertility and a high cure rate. Finally, significant progress has been made in unilateral germ cell tumors of the ovary in which surgical treatment by unilateral salpingo-oophorectomy followed by cisplatin, etoposide, and bleomycin results in not only high cure rates and retention of fertility but will probably be standard therapy for all germ cell tumors of the ovary, including dysgerminoma, a disease most frequently treated in the past by radiation therapy with loss of subsequent fertility.

Six years' experience with screening of a diethylstilbestrol-exposed population.

The physician population delivering obstetric care in Philadelphia between 1950 and 1970 was contacted to ascertain their use of diethylstilbesterol (DES) during pregnancy. Of the 31.8% of the physicians who responded to the questionnaire, 71.8% used DES during pregnancy and 12.7% desired assistance in review of their records. During the 6 years from the initial survey, 830 young women exposed to DES in utero were periodically screened for cervicovaginal abnormalities and clear cell adenocarcinoma. Of these 830 patients 61.7% were found to have cervicovaginal abnormalities, and 65.9% of the patients showed either adenosis or evidence of the prior existence of vaginal adenosis. Eight patients were treated for clear cell adenocarcinoma. Two cases were detected while asymptomatic. Seven of the patients are living with no evidence of cancer, and two of these have survived over 5 years.

Upper genital tract changes associated with exposure in utero to diethylstilbestrol.

Hysterosalpingograms of 60 young women exposed in utero to diethystilbestrol were obtained. In 46 instances, documentation of this exposure was obtained from the mother's chart review or confirmed by the attending physician. In 14 instances, the patients' mothers were sure they had received stilbestrol, but documentation could not be specifically confirmed. Hysterosalpingograms of 23 women being investigated for infertility during the same period that the current study was conducted were also reviewed. In 40 women exposed to stilbestrol, changes in the uterus which differed significantly from those seen in the past in nonexposed individuals were noted. These changes consisted of a 'T-shaped appearance of the uterus,' constricting bands in the uterine cavity, a hypoplastic uterus, and less frequently, intrauterine polypoid defects, synechiae, and in one instance a unicornuate uterus. In 36 of the 40 women gross defects were also noted in the cervix. By comparison, in none of the control subjects were defects noted which could be considered comparable with those seen in the DES-exposed patient.
