333 pre- and peri-menopausal patients with breast cancer entered a programme of open studies on the effect of goserelin. Of the 333 patients, 265 patients were entered into assessable efficacy studies. Efficacy data were analysed from 228 eligible patients receiving 3.6 mg of goserelin administered as a subcutaneous injection of a depot formulation once every 28 days. Mean serum luteinising hormone (LH) and oestradiol concentrations were suppressed by day 22 after the first injection. Subjective response occurred in 68.3% of patients assessed. Objective response (UICC criteria) occurred in 36.4% of patients and the lifetable median duration of response was 44 weeks. Responses were observed in all histological grades of tumour, and regardless of oestrogen receptor status. Treatment was well tolerated with no withdrawals due to possible adverse reactions of which hot flushes (75.9%) and loss of libido (47.4%) were commonly encountered. Goserelin provides an effective well tolerated medical alternative to ovarian ablation in the management of advanced breast cancer.

Twenty-two pre-menopausal evaluable patients with advanced breast cancer (median age 39 years; ER positive 19, unknown three; prior adjuvant chemotherapy 16) were treated with the LHRH agonist goserelin depot (Zoladex). Serum levels of 17 beta-estradiol and progesterone were suppressed by goserelin within 3-4 weeks of therapy, while serum leuteinizing hormone and follicle stimulating hormone titers remained in the low level of the normal range. Complete or partial response was documented in seven of 22 cases (32%) and occurred in all major sites of disease. Tumor response was documented in women regularly menstruating at the start of therapy. Median time to disease progression was 23 weeks; median duration of response was 64 weeks; overall survival was 141 weeks. Zoladex was well tolerated: only hot flushes in 82% and reversible cutaneous pigmentation in the site of injection in 45% of the patients were observed. In our experience the activity of Zoladex was comparable to that of oophorectomy, without the psychological trauma and the morbidity related to surgical castration.

Goserelin is a synthetic analogue of gonadotrophin-releasing hormone (GnRH) [luteinising hormone-releasing hormone (LHRH); or gonadorelin] which stimulates gonadotrophin and sex hormone release in the short term, and then causes suppression with continued administration. Goserelin is given as a subcutaneous biodegradable depot incorporating 3.6 mg of the drug, which is released continuously at an average rate of 120 micrograms/day over 4 weeks. Monthly goserelin depot therapy produces partial disease remission or stabilisation in about 75% of men with previously untreated prostatic cancer, a rate equivalent to that achieved with orchidectomy or diethylstilbestrol (stilboestrol). The response to goserelin is more rapid than to diethylstilbestrol, and goserelin is better tolerated. About 30 to 45% of premenopausal women with breast cancer responded to goserelin using objective assessment criteria, suggesting comparability to ovariectomy. In benign hormone-dependent conditions, preoperative goserelin aids surgical removal of uterine leiomyoma (fibroids) and reduces blood loss, and 6 months of therapy relieves the signs and symptoms of endometriosis. The elevation in testosterone at the beginning of goserelin therapy can result in disease 'flare' in men with prostate cancer, and sex steroid suppression with continued treatment results in hot flushes and loss of libido in most patients. Thus, goserelin is an effective alternative to surgery or estrogen therapy in prostatic cancer palliation, and possibly to ovariectomy in premenopausal breast cancer. Other gynaecological conditions reliant on the pituitary-gonadal axis also appear amenable to hormone manipulation with goserelin.

For almost a century surgical castration represented the initial standard therapy for metastatic breast cancer in premenopausal women with hormone dependent tumors. Today the suppression of ovarian function can also be obtained by the administration of supraphysiologic doses of luteinizing hormone releasing hormone (LHRH) agonists. From April 1987 to February 1989, 23 premenopausal patients with advanced breast cancer (median age 39 years, range 28-52, ER positive 20, unknown 3; prior chemotherapy 17) were treated with the LHRH agonist goserelin depot (Zoladex) at the dose of 3.6 mg. every 4 weeks. Twenty-two patients were evaluable. Serum levels of 17 beta estradiol, progesterone, FSH and LH were suppressed by goserelin and fell to postmenopausal values within 8 weeks of therapy in 77% of cases. Complete response (CR) plus partial response (PR) was documented in 7 of 22 (32%) and occurred in all major sites of disease. Five patients achieved CR (soft tissue 3, viscera 2). Response rate was higher in patients not previously treated with chemotherapy (4/6). In the present series, all responses were seen in women greater than 35 years old, regularly menstruating at the start of treatment. Time to progression for the entire case series was 22 weeks and for responders 64 weeks. Oophorectomy was performed after disease progression in four patients without success. Goserelin was well tolerated. Local cutaneous dyschromia occurred in 45% and hot flushes in 82%. Treatment efficacy of goserelin is comparable to that of oophorectomy, without the psychological trauma and the morbidity related to surgical castration.

Eighty patients with different stages of genital endometriosis were treated with Zoladex, a gonadotrophin-releasing hormone analogue in a depot formulation, injected subcutaneously every 4 weeks. The stages of endometriosis (I-IV) were classified according to the revised American Fertility Society recommendations (AFS criteria) via pelviscopy before and after 6 months of treatment. Fifty-eight second-look pelviscopies were performed with the following objective changes after (before) treatment: Stage IV 0 (3); Stage III, 2 (13); Stage II, 12 (30); Stage I, 19 (12). Twenty-five patients presented with Stage 0 after therapy and were healed. All 57 symptomatic patients showed a subjective response to Zoladex therapy with a significant decrease of the total pelvic symptom score. Thirty-eight patients with infertility wished to become pregnant and so far 16 (40%) have conceived. During therapy, the serum concentrations of luteinizing hormone, follicle stimulating hormone, estradiol and progesterone were significantly suppressed. All patients were amenorrhoeic after 1-2 injections. Restoration of ovarian function with resumption of menstruation occurred within 57-92 days after the last injection of Zoladex (1-2 months after end of treatment). Side-effects were minimal and were those expected of the hypo-oestrogenic state, such as hot flushes, vaginal dryness and decrease of libido.

In patients with locally advanced (bulky) carcinoma of the prostate, definitive radiotherapy is associated with a high rate of local recurrence. The Radiation Therapy Oncology Group (RTOG) has conducted several studies evaluating hormonal cytoreduction (used as an induction regimen) as a means of improving the local control rate. RTOG 85-19 tested an induction regimen consisting of a depot LH-RH agonist (Zoladex) and an antiandrogen (flutamide). Eligible patients were those with bulky primary lesions (stage B2 and C) with disease confined to the pelvis. Zoladex was administered every 29 days via a subcutaneous injection. Flutamide was given by mouth in a dose of 250 mg t.i.d. Administration of the drugs was initiated 2 months prior to start of radiotherapy and was terminated at completion of the radiotherapy course. Radiotherapy consisted of 180-200 rad/day, 4,400-4,500 rad to the regional lymphatics, and 6,500-7,000 rad to the prostate. The primary aim of the study was to evaluate the effectiveness and toxicity of the combined (hormonal cytoreduction plus definitive radiotherapy) regimen. Thirty-one patients were accessioned; 30 are analyzable. The drug-related toxicity appears acceptable. It included appearance of diarrhea before initiation of radiotherapy in two patients, nausea during the 2nd week of drug administration in two patients, and skin rash in three patients. These phenomena appear to be related to flutamide. Hot flashes were recorded in 17 patients. With a minimum follow-up of 2 years, clearance of the primary lesions (by clinical examination) was documented in 28 of 30 patients. During the 1st year, two of 30 patients died (of unrelated causes) with residual palpable tumors. The observed toxicity appears acceptable and the response rate encouraging. A phase III study comparing the tested regimen against radiotherapy alone appears warranted.

Twelve patients with symptomatic uterine fibroid were treated with Goserelin acetate, a depot Gn-RH analogue administered s.c. in a dosage of 3.6 mg every 28 days for a 6 month period. Mean age of the patients was 39 (26-47). A menopausal-like state, evidenced by hot flushes, depression, vaginal dryness, hysteroscopic endometrial atrophy, and hormonal values (FSH, LH, E2), was seen in all patients. After only two months of treatment, a significant reduction was noted in the size of the fibroid, being even greater than that in the following four months. Only one patient in the series underwent surgery. General tolerability of the drug was optimal. These data suggest the efficiency of this type of treatment in obtaining a significant reduction of fibroid volume as well as subjective symptomatology. The cost-benefit ratio is optimal, allowing postponement of surgery and the possibility of vaginal, as opposed to abdominal, hysterectomy and affronting problems of anaesthesiology and post-operative recovery for patients "at risk".

Twenty-seven patients with metastatic adenocarcinoma of the prostate were treated with the new luteinizing hormone-releasing hormone analog, Zoladex (ICI 118,630) for up to ninety-eight weeks. Initially, treatment was randomized between Zoladex 250 micrograms and 500 micrograms self-injected subcutaneously every day for a minimum period of twelve weeks following which a sustained-release, once-monthly depot formulation of Zoladex 3.6 mg s.c. was used. Acute rises in serum gonadotropins and testosterone during the first two days were followed by declines in hormone levels over the following three weeks. Median time to castration with 500 micrograms/day was twenty-two days compared with forty-three days with 250 micrograms/day (p = 0.06). No significant endocrinologic changes occurred during the transfer to the depot, and serum testosterone remained 95 per cent suppressed throughout the duration of the study. After three months the median daily serum Zoladex concentrations ranged between 0.47 and 0.53 ng/ml and were not significantly different among the three dosage forms. No specific correlation among serum Zoladex concentrations, endocrinologic parameters, and tumor response rates were found. Hot flashes initially, and decreased libido were the only common complaints. Zoladex was well tolerated, and no side effects required dose-modification or removal from the study. Tumor response rates up to one year appeared to be comparable to the conventional endocrine therapies. This analog in monthly depot formulation is recommended for further clinical evaluation.

A long-acting LRH agonist (ICI 118630, Zoladex) was given by monthly subcutaneous injection to 25 patients with previously untreated symptomatic advanced prostatic carcinoma. The medication was well tolerated with the only side effect being hot flushes in 15 patients. Subjective improvement occurred in 22 patients, and disease remission or stabilization judged by objective criteria was seen in 21 and 18 patients from the total group at 3 and 6 months of treatment, respectively. Twelve of 18 patients followed for 1 year were still in objective remission/stabilization. Prostate volume measured by ultrasound decreased by a mean value of 75% and urine flow increased significantly. There were significant falls in serum testosterone and gonadotrophin levels and significant although lesser reductions in serum androstenedione and dehydroepiandrosterone. These changes were accompanied by significant reductions in serum acid and alkaline phosphatase and a rise in serum osteocalcin. Four patients (16%) experienced an initial tumor flare. Although only a small number of patients were studied, Zoladex appeared to be a well-tolerated agent for treatment of prostatic carcinoma, with an initial clinical response similar to that seen with standard endocrine therapy.

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.
