Google Richard Scolyer: Top doctor remains brain cancer-free after a year. A year after undergoing a world-first treatment for glioblastoma, Australian doctor Richard Scolyer remains cancer-free.
Scolyer is in the relatively fortunate position of being a world class cancer researcher before getting cancer, so he had the resources of an entire oncology lab to give himself a speculative treatment.
Best hope in this regard is to keep an eye out for a resulting clinical trial, unless you have access to a friendly cancer research lab that wants to replicate the experiment.

Dr Mitchell Berger out of UCSF is the GOAT.
