What radiation regimen do you use to palliate bulky melanoma metastases involving the oral cavity?

I like this 9 Gy x 3 melanoma regimen by Dr. Jens Overgaard from Denmark:

It's an oldie from 1985, but uses roughly the same regimen (9.5 Gy x 3) subsequently found to be the trigger of an abscopal response in a patient progressing on ipilimumab, as reported...

I have successfully used 6 Gy x 6 twice a week for metastatic melanoma.
