Tamoxifen treatment of advanced endometrial carcinoma. A phase II study.

The objective of the present phase II trial was to analyze the efficacy of the antiestrogen tamoxifen in advanced endometrial carcinoma. 32 patients with measurable disease entered the study and were treated with tamoxifen 10 mg 3 times daily. Among 26 patients with evaluable disease remission (partial and complete) was achieved in 8 (30%), no change in 7 (27%) and progressive disease in 11 (42%).

Treatment of advanced breast cancer with progestins.

This paper reviews the theoretical background for the use of progestins in advanced breast cancer and the clinical experience obtained from 13 major studies. The average rate of response is about 30%, with somewhat higher rates when the dominant site of disease is localized to soft tissue and to bones, compared with viscera. Furthermore it seems that cross resistance between progestin therapy and other endocrine therapies is only partial.

Pharmacokinetics of medroxyprogesterone acetate administered by oral and intramuscular route.

The present study was undertaken to elucidate: 1) The relationship between plasma concentration of medroxyprogesterone-acetate (MPA, ClinovirR, Depo Provera, Upjohn) administered both orally and intramuscularly. 2) The relation between dose and plasma concentration of MPA. Nineteen patients entered the study.

CCNU, melphalan, methotrexate, and prednisone (CAMP) versus cyclophosphamide, methotrexate, and 5-fluorouracil (CMF) in the treatment of advanced breast cancer in postmenopausal women.

Sixty-nine postmenopausal patients with advanced breast cancer were randomized to receive treatment with cyclophosphamide, methotrexate, and 5-fluorouracil (CMF) or CCNU, melphalan, methotrexate, and prednisone (CAMP). Response rate (partial and complete remission) was significantly higher with CMF (50%) than with CAMP (20%). Hematologic toxic effects were equally pronounced with the two combinations as were the other side effects with the exception of alopecia, which occurred most frequently with CMF.

Comparative pharmacokinetics of medroxyprogesterone acetate administered by oral and intramuscular routes.

The present study was undertaken to elucidate (1) the relationship between plasma concentration of medroxyprogesterone acetate (MPA; Clinovir) administered by the PO and the IM routes; and (2) the relationship between dose and plasma concentration of MPA. Nineteen patients entered the study. In each patient the plasma concentration was monitored after a single PO and IM administration of MPA at the following dose levels: 100 mg (5 patients), 400 mg (5 patients), 800 mg (5 patients) and 1,200 mg (4 patients).
