I worked for one the first hospitals that was doing genomic testing for oncology patients in the U.S. I am not advocating against genomic testing or precision medicine, but Amerisource Bergen, (at the time) McKesson, and the sales people at the manufacturer were licking their chops at the thought of precision medicine. It was extremely lucrative for some improvements on QoL. I sincerely hope that it’s not cost prohibitive to patients and results in breakthroughs in treatment. But I did watch as a lung cancer drug was administered to patients at the cost of 250k per treatment. I don’t remember how many treatments there were but the cost was insane. The US system of healthcare is absolutely broken and I believe there’s a study that particularly evaluated cancer as a major cause of families depleting whatever savings they had within a couple years of being diagnosed. This is an indictment of the whole system. Not the efficacy of the drugs.
