Earlier this week, I discussed Clínica 0-19, a clinic “making DIPG history in Monterrey” whose doctors claim to be able to successfully treat the deadly brainstem cancer DIPG using intra-arterial chemotherapy and immunotherapy. This week, I discuss what I’ve learned since last week, specifically a lot more about just what it is that these doctors do, why it is scientifically dubious and unproven, and why I am becoming even more harsh in my assessment of this clinic, which shows every indication of being a predatory clinic selling an unproven treatment for a very high price.
