Three treatment modalities have successively dominated adjuvant therapy of breast cancer in non-menopausal women, namely, castration, chemotherapy and tamoxifen administration. The benefits afforded by each of these modalities seem similar when the treatments are compared indirectly by meta-analysis. Once the anti-tumour action of LH-RH analogues and their reversible action on ovarian function had been established, these analogues were used instead of surgical castration in direct comparisons of the three treatment modalities. Most of the patients in these trials had estrogen and/or progesterone receptor positive tumours. According to the current state-of-the-art and whilst awaiting the final results of ongoing trials, we can conclude that: The survival of surgically castrated patients is the same as that of patients who have received CMF-type chemotherapy. The survival of patients on tamoxifen is the same as that of patients who have received CMF-type chemotherapy if tamoxifen is administered for 5 years. It is lower if tamoxifen is given for only 2 years. In 2 out of 3 trials, patients receiving the combined treatment castration plus tamoxifen had improved recurrence-free survival rates compared to patients on chemotherapy (regardless of whether an anthracyclin was included or not. It is too early to comment on overall survival. Combining castration and chemotherapy seems to be advantageous in patients less than forty and in those in whom chemotherapy has not induced amenorrhea. Combining tamoxifen and chemotherapy markedly decreases the risks of disease recurrence and of death but the high standard deviations recorded mean that this statement has to be tempered. Finally, an arrest of ovarian function by LH-RH analogues that is only temporary apparently does not adversely impinge upon results. This has, however, to be proved in an ad hoc trial and the optimum duration of analogue administration has to be established.
