As far as I know there is no foolproof marker of efficacy currently available for antiestrogen drug treatments.In addition, since these drugs are slow acting (in comparison with chemo) signs of efficacy take a long time to show up which is not helpfull when the treatment is not working from the begining or is starting to fail.

However there is hope that a very accurate & very early diagnostic tool of efficacy may be in the works based on this initial small scale study:

Nuclear Medicine Imaging Allows Prediction Of Breast Cancer Patients' Response To Hormonal Treatment

If this pans out, months of useless treatments may be avoided in the case of non responders to hormonal therapy.
