Genetic testing may improve selection of women with ER+ breast cancer for ten rather than five years of hormonal therapy

Genetic analyses of results from 1125 postmenopausal women being treated for oestrogen responsive breast cancer have shown that some of them are more likely than others to have a late recurrence of their cancer and might benefit from ten years of hormone therapy rather than five. Prof Mitch Dowsett told the opening press conference at the European Breast Cancer Conference (EBCC-9) that his research had shown that women who had tumours that were negative for the human epidermal growth factor protein (HER2-) but which were very sensitive to the oestrogen hormone, had more than double the risk of their cancer recurring between five and ten years after surgery and five years of adjuvant hormone therapy.
