We treated 38 patients with newly diagnosed advanced prostatic cancer with monthly injections of a long acting depot preparation of a luteinizing hormone-releasing hormone superagonist (Zoladex depot). After 6 months' treatment 10% of the patients had complete objective regression, 77% had partial objective regression, 3% stable disease and 10% had objective progression. The LHRH analogue does not have the metabolic side effects of oestrogens. Depot luteinizing hormone-releasing hormone analogue may well become a preferred alternative for patients with advanced prostatic cancer.

In order to evaluate the proposed benefit of complete androgen blockade in the treatment of patients with advanced prostatic cancer, we initiated a multicenter prospective and randomized study. At the time of this report 99 patients with newly diagnosed, previously untreated prostatic cancer were randomly distributed to one of the following treatments: group I, orchiectomy plus antiandrogen Flutamide; group II, depot LH-RH analog Zoladex plus Flutamide; group III, orchiectomy alone, and group IV, Zoladex alone. Our preliminary data fail to demonstrate a superiority of total androgen blockade over partial androgen blockade in the treatment of patients with advanced cancer of the prostate.

In patients with histologically confirmed prostate cancer, oestrogen priming with diethylstilboestrol (DES) (3 mg/day) for 4 weeks prior to the first injection of the LHRH agonist Zoladex (3.6 mg depot form) prevented any rise in the serum testosterone concentration. In contrast, in the groups pre-treated with DES, the first, but not subsequent, injections with Zoladex were associated with a marked surge in luteinising hormone. Treatment with DES beyond the time of the first administration of Zoladex did not provide further endocrinological advantage. Oestrogen priming for 1 month prior to treatment with Zoladex may prevent an exacerbation of signs and symptoms of prostate cancer.

The theoretical basis of 'total androgen blockade' in the treatment of advanced prostatic cancer is reviewed. The results of experimental and clinical data in the literature comparing medical or surgical castration alone versus castration plus peripheral antiandrogens are discussed. Most of these studies could not reproduce Labrie's results and do not establish the benefit of total androgen blockade. The author produces his own experience with LHRH analogs alone (Depot Zoladex; 30 patients) compared to orchidectomy plus antiandrogens (17 patients). After 2 years, there is no difference in the progression and death rates between the two groups. Moreover, the administration of an antiandrogen in 15 patients relapsing after first-line hormonal treatment (Zoladex or orchidectomy) produced an objective response in only 2 of them. 9 patients experienced a subjective response but the duration of response was very short (medium 3 months).

The Zoladex (ICI 118,630) multicenter trial included 149 patients with stage B +o D prostatic cancer recruited from 1984 to date. Of them 53 clinical responders on the treatment for 40 weeks or longer were subjected to assessment of antitumour response, overall subjective response, endocrinological response, safety and usefulness. The responders consistently showed a clinical response as evidenced by antitumour response in 32 of 50 patients (64.0%) at week 12 and in 35 of 51 (68.6%) at week 40, and overall subjective response in 42 out of 47 patients (89.4%) at both week 12 and week 40. Endocrinologically, all of the 47 eligible patients maintained a 40-week or longer response. Adverse reactions were observed in 19 out of 73 patients (26.0%), subdivided by the time of occurrence as 15/73 (20.5%) up to week 12, 3/71 (4.6%) between week 12 and week 40, and 5/53 (9.4%) in and after week 40. No patient required the discontinuance of treatment. Usefulness of the drug was observed in 51 out of 52 patients (98.1%). The results indicated that Zoladex in a once monthly regimen may be of great advantage to elderly patients with prostatic cancer, and allow an improved patient compliance: Zoladex may not only produce clinical remission but also improve the quality of life.

Ninety patients with advanced prostatic cancer (15 with stage B, 23 with stage C, and 52 with stage D) were randomized to receive 0.9, 1.8, or 3.6 mg, respectively, of Zoladex depot subcutaneous injection every 28 days for 12 weeks. The serum levels of LH, FSH, and testosterone were elevated after the first injection, and followed by a significant decrease. The suppression of testosterone levels in the blood to castrate levels was observed in all patients except two treated with 0.9 mg. Objective response (CR and PR) was seen in 63.6% (0.9 mg), 47.8% (1.8 mg), and 68% (3.6 mg) of patients according to the Japanese Prostatic Group Criteria. Subjective improvement (performance status, analgesic consumption) was also observed in 75-88% of patients but without a statistically significant difference between each dose group. Only minor adverse effects were found during the treatments. The drug was detected dose dependently in the blood by radioimmunoassay. These results suggest that endocrine therapy with Zoladex depot in doses of 3.6 mg subcutaneously every 4 weeks is a useful alternative to surgical castration in patients with prostatic cancer.

From April 1984 to May 1986, 129 patients with prostate cancer entered a prospective trial with a new LH-RH agonist, Zoladex. Mean age was 72 years (range of 45-94 years) and, in most cases, patients had metastatic disease, not previously treated by chemotherapy or hormone therapy. Patients received a monthly injection of 3.6 mg. Serum testosterone was lowered into the range of castrate levels after 4 weeks of treatment. In 105 evaluable patients at 3 months, a 65% partial response (PR) rate was observed, with 11% stable and 24% progressive disease. Median time to progression was 37 weeks. Analysis of objective criteria revealed 30% PR for prostate volume and 51% CR-PR for prostatic acid phosphatases. Seventeen percent of lytic metastases had recalcified. One hundred twenty-nine patients were evaluable for toxicity. Endocrinological side effects were common: decrease in libido, 92%; impotence, 86%; hot flushes, 48%; and breast swelling or tenderness, 9%. Nonendocrinologic side effects were rare. The treatment is generally well accepted by patients owing to the convenient depot formulation and to the minor side effects.

Fifty-six patients with previously untreated advanced prostatic cancer were treated with the LH-RH agonist Zoladex. Patients have been followed for between 24 and 39 months. The response rate and duration of response have been assessed and related to the degree of differentiation of the primary tumor. All of the patients with well-differentiated tumors responded symptomatically, while the comparable figure for patients with poorly differentiated tumors was 67%. The better differentiated tumors tended to respond longer than their poorly differentiated counterparts (18.75 months compared to 15.9 months, respectively). Overall survival was worse in patients having tumors of higher grade and the mean survival after relapse was shorter. The results confirm the unfavorable prognostic significance of poor histological grade in prostatic cancer and indicate that response to treatment, duration of response, and time to death following relapse are also adversely influenced.

Eighty patients with prostatic cancer have been treated with an LH-RH analogue (Zoladex). Ten had no metastasis, and hormone therapy was used as an induction treatment before curative radiotherapy. The others had metastatic disease and, in some cases, had already received some form of endocrine therapy. Patients received a monthly injection of Zoladex (3.6 mg). No progressive disease was noted among patients with nonmetastatic tumors; of the patients with metastases, those who were previously untreated had a higher response rate (14.8% complete response) and longer progression-free and overall survival. Toxicity was mild in spite of two cases of disease flare.

The trial drug was ICI 118.630 (Zoladex). Inclusion criteria were histologically confirmed advanced prostate cancer (T greater than 2 or N+ or M+), life expectancy greater than 3 months, and no previous radiotherapy, orchiectomy, or chemotherapy. Treatment started in November 1984; 30 patients were recruited. The period of treatment ranged from 6 to 144 weeks (median of 59.5 weeks). One patient died after 6 weeks of rapidly progressive renal failure. Data were updated to the end of August 1987. The mean age was 67.9 years (53-83 years). Subjective response was evaluated by a mean symptoms score (using daytime micturition, nocturia, dysuria, hesitancy, and flow) and a score of three different items: patients' activity, bone pain, and use of analgesics. Only 7.1% of the patients showed a permanent positive response. Four different objective responses (complete, partial, stable disease, and progression) were possible after evaluating the T category, tumor dimensions, metastases, and prostatic acid phosphatase. Testosterone (T) and plasmatic LH levels rose after administration: T dropped below the castration level (1 ng/ml) within a few days and remained constantly low. The rate of progressive disease was 27.6%; disease control was possible in 72.4% of the patients (PR or SD).
