Abstract |
Recently a new non-steroidal antiandrogen ( Casodex) has been shown in animal experiments to possess a potent peripheral antiandrogen effect. In patients with advanced prostatic cancer however, this drug is not peripherally selectively active and blocked central brain androgen-receptors results in a rise of luteinizing hormone (LH) and testosterone (T). We treated 18 advanced prostatic cancer patients with 50 mg Casodex daily for a mean period of 42 weeks. There were no complete objective responses but partial responses were seen in a few patients. In 16 patients there was a greater than 50% reduction of pretreatment PSA levels. Endocrine evaluations showed a significant rise in LH, T and oestradiol (E), reaching peak values within the two first months with subsequent lowering of these levels afterwards but without returning to normal. The general tolerance of the drug was good, gynecomastia being the most frequent side-effect. Libido and potency, when present before start of therapy, were maintained in some patients. We conclude that this compound seems as effective as other antiandrogens, but with improved compliance, and shows less side effects in the management of advanced prostatic cancer.
