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.

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.

A prospective randomised study was performed to test the hypothesis that total androgen ablation, achieved by combining an LHRH analogue, goserelin acetate (
Zoladex
), with an antiandrogen, cyproterone acetate (Cyprostat), is more effective than conventional monotherapy in delaying the time to progression of metastatic prostatic cancer. 525 patients were recruited at 18 UK centres between May 1986 and January 1989, 175 patients being allocated to each arm. Patients were clinically and biochemically assessed at 1, 2, 3, 6, 9 and 12 months after initiation of therapy and then every 6 months until a maximum duration of 48 months. There was no statistically significant difference in terms of median time to progression between the combination treatment arm and either monotherapy arm, although there was a statistically significant difference between goserelin acetate alone and cyproterone acetate alone, in favour of goserelin acetate (p = 0.016). All treatment regimens were well tolerated and cyproterone acetate reduced both tumour flare reactions and
hot flushes
in patients receiving goserelin acetate. It is concluded that total androgen ablation using cyproterone acetate (300 mg/day) and goserelin acetate (3.6 mg every 28 days) confers no advantage in terms of time to progression, to conventional monotherapy, but can reduce certain side effects caused by LHRH analogue treatment alone.

Add-back hormone replacement therapy has been shown to alleviate some of the hypo-oestrogenic side effects associated with gonadotrophin-releasing hormone agonists, including demineralisation of bone. Studies on patients with uterine fibroids have shown that concomitant add-back therapy reduced the efficacy of these agents, but that deferred administration was less detrimental. This trial set out to investigate if deferred add-back therapy could offer any advantages to patients with endometriosis compared with immediate therapy.
Zoladex
[goserelin acetate (3.6 mg every 4 weeks)] was given for 24 weeks either with placebo, with medrogestone (10 mg/day) for 24 weeks (immediate add-back therapy), or with placebo for 12 weeks followed by medrogestone (10 mg/day) for 12 weeks (deferred add-back therapy) to 123 patients. The number of responders measured using the Revised American Fertility Society score (decrease in this score of > or = 50%) was greatest in the immediate add-back therapy group, although there were no significant differences between groups. All three treatment groups showed significant decreases in bone mineral density compared with baseline but smaller losses were generally observed in the add-back groups. A significantly smaller number of patients in the immediate add-back group reported
hot flushes
during the first 12 weeks of treatment compared with the deferred add-back group. In conclusion, it appears that there is no extra advantage to patients with endometriosis being treated with goserelin in delaying the start of add-back therapy.
