Appetite stimulation and weight gain with megestrol acetate

Area of Science:

• Oncology
• Pharmacology

Background:

• Cancer-associated anorexia and cachexia significantly impact patient and family well-being.
• Progestins, like megestrol acetate, show potential in managing disease-related appetite and weight loss.

Purpose of the Study:

• To review early breast cancer data and preliminary findings from a placebo-controlled trial of high-dose megestrol acetate for cancer anorexia and wasting.
• To evaluate the efficacy of megestrol acetate in alleviating cancer-associated weight loss.

Main Methods:

• Review of existing data from breast cancer patients treated with megestrol acetate.
• Analysis of preliminary results from a randomized, placebo-controlled trial involving high-dose megestrol acetate in cancer patients with anorexia and wasting.

Main Results:

• Weight gain was observed in 75% of patients in the high-dose megestrol acetate study.
• Nearly all patients remaining on therapy for 6 weeks experienced weight gain.

Conclusions:

• Megestrol acetate may improve nutritional status and quality of life in patients with cancer anorexia and cachexia.
• While not directly affecting prognosis in hormone-insensitive tumors, megestrol acetate can enhance host resistance through nutritional support.
