He was involved in some new (?) clinical trial for I think about 4 weeks, then had to quit it because of the overwhelming side effects. I believe today he said that treatment "bought him time" for his team of doctors to assess what to do next.
From what I've been able to glean from his comments, he is now undergoing another round of some kind of anti-cancer treatment (chemo?). He said this treatment is "kicking his ass", and he wakes up each day: (1) Thankful to God that he's alive, and (2) he will decide each day if he can handle the rigors of a 3-hour radio show each day.
I didn't take his comments ("make the patient feel as good as possible, for as long as possible") as alluding to palliative care.
At least I HOPE that's not what he meant... :-(
Whatever he’s taking, he’s not losing his hair, so that is a plus.
