Chemotherapy of hormonally unresponsive prostatic carcinoma.

The national Prostatic Cancer Project has evaluated single and combination chemotherapeutic agents for the treatment of patients with advanced prostatic cancer that has been unresponsive to hormonal therapy. Although regression rates have been modest, a number of drugs have shown some efficacy and are now undergoing testing in combination. Current trials of the LH-RH agonists and the antiandrogen flutamide are in progress. These trials have demonstrated a role for chemotherapy in the treatment of the patient who has failed hormonal therapy.
