I, of course, have nothing to contribute about the porta cath. I just want you to know that I think of the two of you and your son (not sure if you have more children or not) a lot. I wish there were something more I could do.
Did you ever find out why they are using a chemo that hasn't worked well for your wife in the past (I know they are combining it with something new, but still....)
I know you said the onc didn't bring up Tarceva, but maybe you need to bring it up. Your wife's "profile" suggests it has a good chance of working..
As far as changing oncs, I would say if you still are considering it, call around now. I would say that with the recent scan results, you could make the case that this is an emergecny and I am SURE that your wife would be seen within a week or two.
You could do that as a second opinion without officially leaving the current onc. That way you wouldnt be putting all your eggs in one basket.
Maybe I am out of line for expressing my opinions on this, but I worry about you both. Sheesh, I worry about us all.
love and fortitude, my friend
