Oct. 12, 2010 -- Scientists have identified a gene that could help predict whether a breast cancer patient will respond to the drug tamoxifen.
A study published today in the British Journal of Cancer showed a potential link between the activity of a gene called BCAR4 and the likelihood that a breast cancer tumor will not respond to tamoxifen hormone therapy.
The study also found that the level of BCAR4 in a tumour was linked to a poor prognosis regardless of whether the patient received tamoxifen.
Tamoxifen is a hormone treatment given after surgery. It was developed more than 30 years ago and is widely used to treat women with breast cancer.
Tamoxifen comes in tablet form and is given for about five years after surgery to help prevent the disease from returning. read more
