The treatment of metastatic prostatic cancer with a potent luteinizing hormone releasing hormone analogue.
|
| Abstract |
Metastatic prostatic cancer generally is treated by either castration or the administration of exogenous estrogens, both of which have significant clinical disadvantages. Luteinizing hormone releasing hormone analogues have been shown to suppress gonadal steroidogenesis in animals and humans. To assess the effect of the administration of a potent luteinizing hormone releasing hormone analogue, (D-Leu-6)luteinizing hormone releasing hormone (1-9) nonapeptide ethylamide, 9 patients with previously untreated stage D2 prostatic cancer were treated with this agent for 3 to 8 months. By 3 months of treatment all patients demonstrated a significant decrease in serum testosterone and a decreased peak serum luteinizing hormone and testosterone response to the acute administration of the analogue, with no change in baseline serum luteinizing hormone or prolactin. These data suggest that this analogue acts by decreasing the pituitary release of luteinizing hormone. No major adverse effects were noted with this treatment modality, and all patients were symptomatically improved and demonstrated a decrease or stabilization in tumor activity as measured by prostatic computerized tomography or ultrasound scan, prostatic acid phosphatase and bone scan. A representative case is presented. Luteinizing hormone releasing hormone analogues may prove to be valuable new agents in the treatment of advanced prostatic cancer.
