jetgirl,
Sorry to hear of your Mom's liver mets. While my husband hasn't had liver mets, he is Stage IV for bilateral inoperable lung mets. I do know that many patients have lived for some time with chemo treatments. No doubt someone else will be along to share their stories. It certainly isn't usually a death sentence by any means. I'm sure your Mom's oncologist will be able to find a chemo protocol for her that hopefully will be successful.
Good luck and Godspeed.
