From July, 1980, to June, 1983, 319 patients with newly diagnosed metastatic prostatic cancer were randomized to one of three treatment protocols: diethylstilbestrol (DES) or bilateral orchiectomy, cyclophosphamide plus 5-fluorouracil plus DES, and estramustine phosphate (Emcyt). Ninety-three per cent of 296 patients were eligible for evaluation. This report shows no difference in survival, disease-free progression time, or status regarding pain at entry. Other prognostic factors failed to reveal any difference within any of the treatment protocols.

Patients with advanced prostate carcinoma that had been stabilized by orchiectomy (ORCH) or hormone therapy for at least 3 months, were randomized to either diethylstilbestrol (DES) alone or DES plus Cytoxan or DES plus Emcyt. A total of 188 patients were randomized between July, 1976 and February, 1982 of which 161 were evaluable for objective response to treatment. Objective response rates, response duration, or survival experiences were not demonstrably different between treatment arms, either for all patients or within good or poor prognosis groups determined by initial pain or acid phosphatase level. Subjective improvements in performance status were small for each treatment. Pain relief was somewhat greater in the chemotherapy-hormone combinations than in the DES/ORCH, but the advantage was not statistically significant. Side effects were primarily nausea and vomiting and leukopenia, mostly in the DES + Cytoxan arm. The duration of stabilization prior to entry did not influence response overall, although there were opposing trends within each of the two chemotherapy arms. The premise for combining antitumor agents with hormones before hormone failure is still felt to be a more logical approach than waiting for the ultimate hormone failure, and a combination of hormones plus two antitumor agents is being evaluated in a subsequent ongoing trial where a more rigid design limits the duration of the preentry period of hormone stabilization.

Androgen-deprivation therapy, usually with combined androgen blockade, is standard initial treatment for advanced prostate cancer. With failure of initial treatment, as indicated by rising prostate-specific antigen (PSA) levels, second-line hormonal therapy is usually instituted. Over the past several years, it has become increasingly clear that systemic chemotherapy has an important role in hormone-refractory disease. Phase II trials have demonstrated high PSA and measurable disease response rates with taxane single-agent and combination treatments. One recent phase III trial showed that docetaxel (Taxotere)/ estramustine (Emcyt) significantly improved overall survival, progression-free survival, and PSA response rate compared with mitoxantrone (Novantrone) plus prednisone. Another phase III trial demonstrated that docetaxel given every 3 weeks plus prednisone significantly improved overall survival, PSA response rate, pain relief response rate, and quality of life compared with mitoxantrone and prednisone. On the basis of these findings, every-3-week docetaxel plus prednisone is now considered standard first-line therapy for metastatic hormone-refractory disease. There is considerable optimism that treatment can be further improved. Studies of taxane combinations with bevacizumab (Avastin), thalidomide (Thalomid), bortezomib (Velcade), antisense Bcl-2 oligonucleotide, mTOR inhibitors, epidermal growth factor receptor inhibitors, and KDR inhibitors are under way. Randomized phase III trials in progress or planned are examining docetaxel in combination with imatinib mesylate (Gleevec) or calcitriol and docetaxel/prednisone in combination with bevacizumab and an antisense clusterin compound. Other promising systemic agents include epothilones and atrasentan, and promising vaccines include Provenge, GVAX, and Prostvac.
