Stage, estrogen receptor status, treatment and survival of 29 men with breast cancer attending the Breast Clinic of the Johannesburg Hospital between 1976 and 1985 are reviewed. Most patients had locoregionally advanced disease at presentation. Estrogen receptors (ER) were detected in significant concentration in 15/23 (65%). Local control was achieved in the majority, 19/26 (73%), by either surgery or radiation therapy alone or by combined modality treatment. Fifteen of 23 patients tested (65%) were ER-positive (greater than 10 fmol/mg protein). For patients with metastatic disease hormone receptor status was predictive of response to hormonal manipulation. Tamoxifen was the most acceptable and frequently used form of hormone therapy with 7/12 patients responding. Combination chemotherapy gave a response rate comparable to that seen in women with breast cancer.

One hundred twenty nine patients with T1 N0 M0 breast cancer were selectively treated with QUART. Mean age was 50 years. Ninety-eight patients (76%) were N- and 31 (24%) were N+. N+ cases received chemotherapy or Tamoxifen if R+. Patients evaluated are 95/129 in a 3 years average follow-up (range 2-7 years). Overall actuarial survival rate at 5 years is 88.9%. Three patients died; local relapses were 3/95 and metastases 3/95. Overall treatment tolerance was satisfactory and esthetic results were good.

The Christie Hospital Tamoxifen Trial was a randomised trial to assess the efficacy of tamoxifen (Nolvadex) as an adjunct to surgical treatment for operable breast carcinoma. From 1 November 1976 to 1 June 1982 1005 patients were registered, of whom 961 are evaluable. Following surgery, premenopausal women were randomly allocated to either tamoxifen (TAM) 20 mg/day for 1 yr or to have an irradiation menopause. Postmenopausal women had TAM 20 mg/day for 1 yr or no further treatment (controls). The analysis at 7 yr shows that there is no statistically significant difference in the overall survival for premenopausal women between those given TAM and those given ovarian irradiation. Similarly for the postmenopausal women there was no significant difference in overall survival between the TAM and control groups. However, if the series of 961 patients is analysed as a whole and allowance is made for node status then the TAM-treated patients show a significant survival benefit (P = 0.05). There was also a statistically significant delay in first relapse for the TAM-treated patients (P = 0.04); with a particularly marked reduction in distant metastases in postmenopausal patients (P = 0.06). TAM was extremely well tolerated, with very few side-effects.

Out of 79 patients with metastasized carcinoma of the breast in 33% (6 patients) a response to a Tamoxifen therapy could be observed. For complete remissions the remission periods were 12.3 months, for partial remissions 9.9 months and in the group of constant findings 4.9 months. Preferably metastases of the soft parts respond to the therapy. The side effects are very insignificant. The indications for the tamoxifen therapy are represented as well as the importance of the determination of hormone receptors.

A series of 301 cases of male breast carcinoma has been analysed; of these, 292 have been treated at The Christie Hospital, Manchester and followed-up for a maximum of 15 years. The mean age was 63 years. The corrected survival was 52%, 38% and 36% at 5, 10 and 15 years respectively. For clinical Stage I, the 15 year survival was 61%. Since 1976, adjuvant Tamoxifen for one year has been administered to patients with operable Stage II (path) and Stage III disease following surgery and radiotherapy. Twenty-three patients so treated have a corrected survival of 55% at 5 years compared to 28% previously. Of 22 tumours assayed for oestrogen and progesterone receptors, 86% showed a positive result. For recurrent/metastatic disease, the drug Tamoxifen is recommended as the treatment of choice.

The hormone-dependence of malignant melanoma is brought to mind by some epidemiological facts (rarely found in children, more frequently in females, higher frequency in case of prolonged use of oral contraceptives from an early age). On the other hand, estrogen receptors can be found in about 30 p. 100 of malignant melanomas. Starting from this hypothesis of a sub-population of hormone-dependent malignant melanomas, it seemed of interest to us to study the efficiency of an anti-estrogen, namely Tamoxifen (Nolvadex) in the management of metastatic malignant melanoma. It was used at a 40 mg daily dose-regimen on four patients (three post-menopausal females, one male) with multiple estrogen positive cutaneous metastases. In post-menopausal women, two cases of total regression were observed, associated with a distinct increase in progesterone receptors while under treatment and with a return to the initial stage when the treatment was stopped. This phenomenon can be explained by a double self-contradictory effect of the drug, already well known in other hormone-dependent cancers such as those of the breast or the endometrium, namely an anti-estrogen result on the tumoral growth and an estrogen result as attested by the synthesis of progesterone receptors. Certain malignant melanomas therefore behave as endocrine-dependent tumours and may so answer an anti-hormone treatment through a competitive fixation on estrogen-receptors. Our clinical results are in agreement with such a theory since Tamoxifen is at best effective on cutaneous metastases of post-menopausal women. The overall efficiency on all metastases is of the order of 10.6 p 100 (complete or partial regression).(ABSTRACT TRUNCATED AT 250 WORDS)

Tamoxifen (ICI 46474) is the trans-isomer of 1(p-beta-dimethylaminoethoxy-phenyl)-1, 2-diphenylbut-1-ene. In several but not all mammal species it is a potent anti-estrogen. It is thought to act by blocking estrogen receptors. Patients were 68 women with advanced primary carcinoma of the breast, recurrences in the chest wall or soft tissue metastases. The oral dose of tamoxifen was either 10 mg or 20 mg twice daily. Patients were seen and laboratory tests done monthly for 6 months. Side effects were usually trivial and their incidence was the same at both dose levels. Of 26 patients who showed a reduction in tumor size to half or less, 5 had been in remission for over a year and another 10 for over 6 months. Some tumor responses were spectacular. The drug was less effective for bone deposits. In this study 12 of 33 patients (36%) receiving 10 mg of tamoxifen twice daily showed a definite response while a futher 8 (24%) showed a partial response. A definite response was seen in 14 out of 35 (40%) receiving 20 mg twice daily and a partial response in a further 13 (37%). The total response for low dosage was 60% and for high dosage 77%.

Thirty-eight metastatic breast cancer patients were treated with aminoglutethimide. All patients had progressive metastatic disease following initial response to Tamoxifen therapy. Thirty-two patients were evaluable for response, of these, two patients (6%) had complete remission, 13 patients (41%) had partial response, and six patients (19%) had stable disease. Eleven patients (34%) had progressive disease. The most common side effects were transient skin rash, lethargy or dizziness. Four patients' (11%) treatment was discontinued because of either skin rash or dizziness within the first two weeks of the study. These data show that aminoglutethimide is an effective agent following tamoxifen therapy.

The effect of tamoxifen therapy on plasma hormones in the pre- and postmenopausal state was studied in a young patient with breast cancer. Tamoxifen therapy was carried out for metastatic disease prior to (premenopausal) and after oophorectomy (surgical menopause). Changes in luteinizing hormone, follicle-stimulating hormone, prolactin, and estrogen were noted and were corroborated with the therapy or oophorectomy. The findings support some of the previously reported changes in those hormones that were noted in conjunction with tamoxifen therapy.

A large controlled clinical trial with the admission of 1005 patients was carried out using tamoxifen as adjuvant treatment for women with operable carcinoma of the breast. Results were analysed for the first 906 evaluable patients randomised up to December 1981. After mastectomy premenopausal women were randomised to receive either an irradiation menopause or tamoxifen 20 mg daily for one year. Postmenopausal women were randomised to receive either tamoxifen 20 mg daily for one year or no systemic treatment (controls). Analysis at five years suggested that for premenopausal women there was no significant difference between an irradiation menopause and tamoxifen in terms of survival, local recurrence, or distant metastases. Tamoxifen had no appreciable side effects. For postmenopausal women there was a trend in favour of tamoxifen with regard to survival and incidence of distant metastases, and the difference became statistically significant for those patients with four or more positive axillary nodes. If long term results of these studies show only an improved quality of remaining life with tamoxifen, then this drug could be an important contribution to adjuvant treatment.
