Glad things are moving along. Often the wait creates more anxiety than the actual treatments. It seems pretty shocking that none of the doctors wanted dental clearance.

Since your boat has left the harbor you gotta deal with what you got. I would watch very closely for side effects and get back here as soon as things start up, which they will.

If chemo side effects become too harsh there are other options like going to weekly or even changing drugs. Rads often kick off numerous side effects so be ready.

What is the situation on PEG? You did not state he has one. If not, that is great but be on the watch if eating and drinking become too difficult.

Make absolutely certain he is getting at least a quart or more of liquid down daily. Watch for any signs of dehydration and get some saline right away to ease it out.

Good luck,
Don
