Yes, such treatments have been in trial for a couple decades at NIH, showing complete response in a segment of the patients for certain cancers. The therapies harness each individual's immune system to direct it's attack to the mutations specific to their tumors.

Iovance is on the brink (should have been approved in the next month or two, but has been delayed because of "staffing shortages" at the FDA) of getting FDA approval for Tumor Infiltrating Lymphocytes adoptive cell therapy.

Besides the special labs used for the cell processing (managed by Iovance), the therapy is not a whole lot different from stem cell transplants, so any hospital that helps patients with blood-bourn cancers can provide this new therapy to melanoma (and soon, other cancer) patients.

P.S. I'm an 11-year survivor post-TIL therapy for Stage 4 melanoma at NIH.
