title: Endocrine ablation in breast cancer patients who have failed cytotoxic therapy.
abstract: Between 1972 and 1979, forty-six women underwent endocrine ablative surgery, having failed combinations of chemotherapy, radiation, and surgery (including oophorectomy). All had clinically measurable disease; nearly half were afflicted with bone pain. Each was judged to be a candidate for the procedure by estrogen receptor studies (52%), response to L-dopa (39%), or response to prior oophorectomy (8%). All were followed to their death or to the present, with a minimum of 12 months for those alive. Thirty-one (67%) were improved, and disease was arrested in five (11%) for a median time of 13.5 months. There was no difference in response rates or intervals between estrogen receptor-positive and L-dopa-positive groups. Response was not correlated with disease-free interval or menopausal status. Best results were achieved in those with metastases confined to an organ system, particularly the skeletal complex. The procedure is withheld in those with brain metastases. Postablative chemotherapy appeared to prolong the control interval, though numbers are small. The low morbidity and mortality (one death) of midline adrenaloophorectomy combined with the high incidence of recapture of disease leads us to recommend this procedure in appropriately selected patients who have previously failed other therapeutic modalities.
