Tamoxifen and endometrial carcinoma: alterations in estrogen and progesterone receptors in untreated patients and combination hormonal therapy in advanced neoplasia.

Abstract:

:Estrogen receptors and progesterone receptors were measured in tumors from patients with previously untreated endometrial carcinoma before and after a 5-day course of tamoxifen citrate. On initial biopsy, 13 of 25 tumors (52%) were progesterone receptor-positive, whereas 21 of 25 tumors (84%) were progesterone receptor-positive after tamoxifen. Grades 1 and 2 tumors were more likely to demonstrate this increased incidence of measurable progesterone receptors. Considering these results, and the work of others who have shown that progesterone receptor-positive metastatic endometrial cancer is more responsive to progestin therapy than are progesterone receptor-negative tumors, we instituted a phase II clinical trial of tamoxifen plus progestin for patients with recurrent endometrial carcinoma. Thus far, however, the 33% total response rate achieved with the combination therapy has not been superior to standard progestin therapy.
