Abstract
High-dose ketoconazole, 400 mg orally every 8 h, was administered in two groups of patients with metastatic prostate cancer. Group A consisted of 10 patients who had not undergone orchiectomy and Group B, eight patients who had orchiectomy prior to the study. Significant declines in testosterone, androstenedione, and dehydroepiandrosterone levels, reciprocal elevation of the gonadotropin levels (FSH and LH), and a persistent fall in serum acid phosphatase levels were observed in Group A patients. Three Group A patients achieved a partial objective remission (duration 9, 41+, and 69 weeks); four patients, stabilization of their disease for a median of 33.5 weeks (range 16-40+ weeks); and two progressed (The National Prostatic Cancer Project Criteria). Stable disease in two Group B patients (7 and 20 weeks) and progression in four patients were observed. Gastrointestinal irritation was the main toxicity and was similar in both groups. Two Group A patients developed symptomatology consistent with adrenal insufficiency. Ketoconazole can suppress androgen production and has a beneficial role in the hormonal therapy of patients with prostate cancer who have not undergone orchiectomy.
