Glad to hear you've had a good response, and hope Dr. D is right. He's a great doc - did my HAI, and my general onc regularly consults with him on my scans. I was maybe in a similar boat to you - major shrinkage in liver tumors from systemic chemo, then calcification of much of what was left via HAI. But still my liver was swiss cheese with so many spots on it, and Dr D recommended against any attempt at resection. I stayed on HAI as long as they would let me (maybe longer than I should have), and quit when my liver counts got very high. However, ever since that forced break in chemo, all the spots have stayed completely stable, and I'm now going on 8 months without any chemo whatsoever. Of course things could become active again any day, but am thankful for the extra time I've been given. Anyway, just wanted to provide you a little hope that there is some sense to what Dr D is suggesting, even if the odds aren't great (but then again, we stage IV-ers know about long odds). Hopefully you will have as good or even better results with your treatment.
