Premenopausal Study. Twenty-five pre- or perimenopausal patients with advanced breast cancer were treated with leuprorelin acetate 3.75 mg (n = 9) or 7.5 mg (n = 16) every 4 weeks. Serum levels of gonadotrophins and oestrogens were suppressed markedly by both doses and there was no indication that the lower dose was less effective as an oestrogen suppressant. There were four objective responders to the 3.75 mg dose and six to the 7.5 mg dose. Toxicity was confined almost entirely to hot flushes, which occurred in 17 patients. Leuprorelin acetate is therefore an effective agent in the treatment of premenopausal breast cancer patients. There appears to be no major detriment to the use of 3.75 mg rather than the 7.5 mg dose. Postmenopausal Study. Fifteen postmenopausal patients with advanced breast cancer were treated with monthly injections of leuprorelin acetate 7.5 mg to assess the clinical activity and endocrine responses to treatment. None of the 15 patients showed an objective response to treatment, although four patients had stable disease for at least 6 months. Endocrine effects after 4 weeks' treatment included major suppression of serum gonadotrophins to below 10% of pretreatment values and decreases in the level of serum testosterone in 12 of 14 patients. In this group there were no changes in oestradiol levels, although we had previously observed suppression in postmenopausal patients treated with goserelin. In common with other gonadotrophin-releasing hormone analogues, leuprorelin acetate cannot be recommended as a treatment for postmenopausal breast cancer.

Six patients with symptomatic leiomyomata uteri and in whom surgical treatment was indicated received, during 3 months, intramuscular leuprolide acetate, 3,75 mg monthly, in order to 1) achieve a reduction of myomata size and 2) recover an anemic patient before surgery. In every patient, amenorrhea was induced since the second month of treatment. A significant decrease of myomas sizes was achieved. The reduction of the volume of the largest myoma in each case, varied between 51% and 77% (x = 60% +/- ES 4,3) LH and estradiol plasma levels diminished significantly and FSH did not changed in response to treatment. Side effects were well tolerated. Hot flashes were present in all patients, headaches in 2 and loss of strength in 2. Surgery was accomplished after 3 months of treatment. Myomectomy was performed in 5 cases and total hysterectomy in 1. Uterine shrinkage and the period of amenorrhea induced by Lupron-depot facilitated hysterectomy and myomectomy techniques and the recovery of one patient with a severe anemia.

Leuprorelin acetate is a synthetic nona-peptide analogue of the naturally occurring gonadotrophin releasing hormone LH-RH (hypothalamus), used in the treatment of sterility, endometriosis or prostatic cancer. In a 35 year old woman, treated with leuprorelin acetate, after 5 months treatment, the side-effects (hot flushes, sweating, sleeping disorders), appeared to be rather unbearable. Medication was ended. The endocrine reversion to the normal physiological balance was association with high fever (38.9 degrees C) during an 8 day period. Increasing scotomas resulted in a gradual loss of eyesight in one eye, associated with a normal visual acuity. Unilateral papilloedema was observed, indicating the possibility of tumor cerebri. Fluorescein angiography demonstrated an intense leakage of the right optic disc. No signs of retinal vascular malformations were seen. The eye pressure was normal. No signs of hemorrhages were observed. Visual field examination showed an enlarged blind spot with a few scotomas above the centre of fixation. CT scan of the brain was normal, the cerebrospinal fluid (CSF) was normal, indicated by IgG production. Six months after ending the leuprorelin acetate treatment, the eyesight was spontaneously 100% recovered. It is most likely that leuprorelin acetate is responsible for the emergence of pseudotumor cerebri. As described by Prof. Sidi et al(1), leuprorelin strongly induces increased liquor pressure, being the intermediate mechanism between hormonal treatment and an ante grade mechanical force, on the optic nervus. Because of the risk of permanent loss of eyesight, it is strongly advised to verify eye parameters conscientiously during leuprorelin treatment.
