Recall that former President Jimmy Carter made a quite unexpected and spectacular comeback from melanoma that spread to his brain and liver. Think this was 2015 timeframe. He was treated with a Merck drug marketed as Keytruda. Quick read of an older article mentioned it costs $12,500 a month, and was under trials, and so may still not be released to the general; public. Several articles contrasted why Sen NoName didn't respond the same way. Maybe it was withheld for his use? Lots of Doctors names in the articles. Might find time to dig a little more later, but have to put a Briskit in the Smoker for the next few hours!
