After the Burzynski Clinic, the next brain cancer treatment we were evaluating for my Mom before she passed away was using Tumor Treating Fields. We had started the paperwork process to get her into the program in Boston. It was a little bit of a hard sell as it would have required her to have her head shaved for as long as the treatment took (which could have been years).
Here is great TED talk that shows the efficacy for treating cancers of all types. http://www.ted.com/talks/lang/en/bill_doyle_treating_cancer_with_electric_fields.html
