[Hormone therapy of metastasizing breast carcinoma]

In patients with metastatic breast cancer, cure is almost always an exception, irrespective of the therapy given. Thus the preservation of the quality of life or palliation in case of symptoms must be the principal goal. Only a small group of patients with their tumour showing a highly aggressive behaviour should be considered for primary chemotherapy. Aggressive tumour growth is then characterized by negative hormonal receptors, short disease-free interval and predominant visceral tumour growth. For all other patients there is not enough advantage to justify the clearly higher toxicity of a primary chemotherapy. This majority of patients with metastatic breast cancer can profit to a higher degree from hormonal treatment. Irrespective of the type of the hormonal therapy, the response rate is positively correlated with postmenopausal status, high hormonal receptor expression, al long disease-free interval, no previous adjuvant therapy and higher age. Advantages and problems of the various forms of hormonal manipulations are discussed. The recommended sequence of therapy represents only a handrail that needs to be adjusted carefully, according to the individual situation, the needs and expectations of the patient and in due knowledge of the toxicity of each hormonal substance. Combinations of different hormonal agents do not yield an additional benefit and should therefore be dropped for a sequential approach.
