Sheryl,
I hope you soon obtain access to Tykerb.
Get also a look at the just released results of a small trial of
Xeloda+Temodar
for metastatic brain cancer in the article section at:

Xeloda®/Temodar® Effective for Breast Cancer Spread to Brain
If this regimen is suitable for you your onc may be able to prescribe it off label.
Good luck!
