Another update:
The 4th round of chemo didn't take, and she did 2 rounds of the radioactive bullets. Sadly, it didn't work, the tumors did grow, but seemed to have slowed a little. And there are no new liver mets, although she hasn't been on chemo for 4 months now. Also no new mets anywhere else, but there is some lymph node involvment in the bowel and pancreatic areas. They started a new chemo regimin today, ivinotican + 5FU (or erbitux), but she had an allergic reaction to the 5FU, so now it's just ivinotican.
Dr. Lenz at USC is amazing and will keep coming up with options as long as she wants to pursue them.
We started her with physical therapy, too, since she is quickly becoming deconditioned. A tip: have your nurse practitioner write a prescription for physical therapy, then medicare picks up the cost.
Hope this helps someone.
