High-Dose Megestrol in Treating Patients With Metastatic Breast Cancer, Endometrial Cancer, or Mesothelioma

November 5, 2013 updated by: St. Vincent Medical Center - Los Angeles

Phase I/II Study of High-Dose Megestrol in Breast or Endometrial Carcinoma or Mesothelioma

RATIONALE: Some hormones can stimulate the growth of some types of cancer cells. Hormone therapy using megestrol may fight cancer by reducing the production of these hormones.

PURPOSE: Phase I/II trial to study the effectiveness of high-dose megestrol in treating patients with metastatic breast cancer, endometrial cancer, or mesothelioma which cannot be treated with surgery or radiation therapy.

Detailed Description

OBJECTIVES: I. Evaluate the clinical effects of high-dose oral megestrol in improving regression rate and prolonging survival in patients with breast or endometrial carcinoma or mesothelioma. II. Evaluate the immune, endocrine, and clinical effects of this regimen, with particular attention to effects on cachexia.

OUTLINE: This is a randomized study. Patients are stratified by performance status, dominant site of disease, and prior treatment with megestrol. Breast cancer patients are randomized to one of 3 doses of oral megestrol (800, 1,280, or 1,600 mg/day, divided qid). Female patients with other tumor types are nonrandomly assigned to receive oral megestrol at 1,600 mg/day. Male patients are nonrandomly assigned to a dose-finding study of megestrol. The first patient cohort receives megestrol at 480 mg/day in 3 divided doses, with further escalation for subsequent cohorts as tolerated. All patients continue therapy for at least 8 weeks, with treatment discontinued upon progression. Measurable lesions are evaluated every 2 months.

PROJECTED ACCRUAL: 9 evaluable breast cancer patients at each dose level will be entered; 14 patients will be required for each of the other disease categories. (As of 11/92, the study is temporarily closed to patients with prostate cancer.)
