Who discusses and prescribes TTFs at your facility?  

At our institution it has been the radiation oncologists. This has been mainly due to early physician adoption of the treatment modality. In light of the recent JAMA paper and recent abstract at SNO demonstrating long-term efficacy, I offer TTFs to all my GBM patients.As an aside, I personally think...

Strong multi-disciplinary support is key to developing a robust TTF program.  Our neuro-oncologist and surgeons are fortunately on board with discussing this as a standard option for GBM patients.  TTF is prescribed by the radiation oncologists at our institution.

i agree with the above and encourage more radiation oncologists to add TTF to their practice.  I suspect more indications forthcoming.
