Thanks for writing in.
I am afraid that your wife had metastatic disease to start with and it is not possible on today's date to cure it. The only good thing is that she had the spread limited to bones only and had a good response to therapy. Currently she is mainlining the response to hormonal therapy.
Some patients with bone-only metastatic disease may have long duration of control (5-10 years). I sincerely wish she falls within this category.
As of now, you need to continue the anastrozole with periodic imaging (PET-CT or bone scans). At this point I don't think there is any need of stereotactic radiotherapy. There is no reason to believe that it will lead to cure. We can reserve it for a later date if she has pain over those sites and there is evidence of disease flare at those sites.

Hope I have answered your query. I will be happy to answer any follow-up queries.
Best Wishes,

Your observation that disease flare scares me , hence thinking of sterotactic local treatment so visceral spread can be prevented. Also can anastrozole and zometa rectify lesion. This make or break situation has disturbed me a lot Hence requesting you to guide me .I am clinical practationer had my MBBS in 1978..

Stereotactic radiation cannot prevent spread of disease to viscera later, it is only for local control.
Anastrozole and zometa can definitely control the disease for certain period of time, which varies from patient to patient. But as I said, cure is not a realistic goal of therapy.
