My Dad died from metastatic stage-IV melanoma. The gene therapies (which were extremely expensive) weren't effective beyond adding maybe an extra 6-8 weeks. I'm interested if the tuberculosis actually "killed" the melanoma or if it caused an unusually aggressive autoimmune response that happened to knock out the melanoma. I'd like to see if there's a case study available on that treatment method.
