Like Christine, I know nothing about this sort of advanced drug therapy, but I am glad that you and your mom have found such an approachable (and knowledgeable) doctor.

A friend of mine with an aggressive breast cancer also was told by MDA docs what sort of drug mixture she should be given, and she also received the treatment from an MDA-referred MO near her home, several hundred miles from Houston. (In her case, surgery was possible, and that was done at MDA. It's been several years, and she's doing just fine.)
