It all comes down to what your comfortable with, but here are a few things to consider:
Duke has one of the top brain tumor centers in the world.
If you look at Dr Arenson's approach to "cure" at
http://www.edwardbarensonmd.com/brain-tumor-treatment-cure.h
you will see that their mode of treatment is radiation with concurrant chemotherapy, chemotheray and biotherapeutics. This is nothing new. Any major brain tumor center - like Duke - offers this. In fact, Duke offers a variety of options including the standard of care approach, clinical trials and off-label treatments. Two of the treatment approaches we've employed in the last 3 years have been off-label and Duke has helped get them approved with my insurance.
I have bias to be sure, but I don't believe you can do better than Duke. Again though, and I stress this; you need to be comfotable with your choice.
