PURPOSE Hepatocellular carcinoma (HCC) is generally considered as a sex hormone-dependent tumor, and hormonal therapy has been proposed as a strategy for the treatment of HCC. The aim of the study is to investigate the effect of megestrol acetate, a synthetic progesteronal agent, on growth of HepG2 cells in vitro and in vivo. EXPERIMENTAL DESIGN Cell growth in vitro was assessed by a colormet...

In the present study, solid dispersion nanoparticles with a hydrophilic polymer and surfactant were developed using the supercritical antisolvent (SAS) process to improve the dissolution and oral absorption of megestrol acetate. The physicochemical properties of the megestrol acetate solid dispersion nanoparticles were characterized using scanning electron microscopy, differential scanning calo...

BACKGROUND Megestrol acetate is an effective treatment for improving appetite and increasing body weight in patients with cancer-associated anorexia. However, Megace oral suspension (OS), a micronized formulation of megestrol acetate, has low bioavailability in the fasting state. To overcome this limitation, a nanocrystal formulation has been developed. This study was performed to evaluate the ...

BACKGROUND Interleukin-15 (IL-15) and interleukin-18 (IL-18) are potential regulators of body composition in humans. The authors previously reported that megestrol acetate ingestion causes a large accumulation of adipose tissue and reduces muscle mass. Therefore, the purpose of this investigation was to evaluate the effects of megestrol acetate ingestion on circulating IL-15 and IL-18 concentra...

Weight loss is known to impact survival among patients infected with human immunodeficiency virus (HIV) even in the era of highly active antiretroviral therapy (HAART). In a randomized trial, we compared the effects of 2 months of treatment with either megestrol acetate (800 mg every day) or oxandrolone (10 mg twice per day) on body weight and composition in patients with weight loss of > or =5...

We describe a case of diabetes mellitus induced by megestrol acetate in a patient with the acquired immunodeficiency syndrome. Metabolic studies including an arginine infusion test excluded an insulinopenic state and suggested insulin resistance as the underlying mechanism for hyperglycaemia. Withdrawal of megestrol acetate resulted in rapid correction of all metabolic abnormalities and elimina...

BACKGROUND Hot flashes are frequent in postmenopausal breast cancer patients, especially when treated with tamoxifen. Estrogen replacement therapy is the most effective treatment for hot flashes, but its use is controversial in breast cancer survivors. Progestins may offer a good alternative for the control of hot flashes in this setting; in particular, oral megestrol acetate has been proven ef...

OBJECTIVE To determine the cost-effectiveness of initiation of second-line hormone therapy with letrozole in the treatment of advanced breast cancer in postmenopausal women in Canada, compared to megestrol acetate. METHODS A modified Markov model, incorporating seven health states, was designed to simulate the treatment of patients with advanced breast cancer from second-line hormone therapy ...

In this report the authors describe a woman with low-grade endometrial stromal sarcoma who was treated with total abdominal hysterectomy and bilateral salpingo-oophorectomy. After receiving megestrol acetate continuously for 19 years for chronic hormone suppression, she began to experience progressive dementia. Magnetic resonance imaging revealed 11 separate intracranial meningiomas of various ...
