My dad diagnosed in 2013 69 years old…….

I wanted to tell you a little about my dad. He is 69 yo, dx with cholangiocarcinoma in July 2013. He was dx by just a routine ERcp. He also has ulcerative colitis and primary a sclerosing cholangitis. At that point we were trying for a liver transplant but they had denied him because of some small distant blockages in the distal part of the heart. That was in August. In late September he had Pdt and started chemo in October. He did 8 rounds (16 tx) of gemzar and cisplantin he done great on chemo finished in April 2014 had a scan afterwards they thought the CA. Had shrank by 50% he they started 5 high strength doses of radiation in June and done great with them as well. He felt great through August. Then he started feeling bloated and crummy, jaundiced just feeling really bad. So called his stent dr ( he has had stents since June 2013 being changed every 2-3 months.) he thought maybe stents were clogged so brought him in early and changed them his bili was 4.8 at that time it actually did not help anything his bili was over 7 by the next week. In September they decided to do external biliary drain. He had numerous problems with this and lost 50 lbs. after many changes of tubing etc they pulled it in Nov 13. He had saw his oncologist on Nov 7who had pretty much said there isn’t anything that can be done I am leaving for 3.5 month maternity leave you need to go home with hospice she said of you ever bounce back from this which I don’t think you will you are more than welcome to see me again( he was in severe pain with the drain in was taking oxys every 4 hours and had duragesic patch)So a few days after that we decided hospice wasnt what we were ready for. Keep in mind at this visit he still had the external drain and was so very ill from it. He had a stent change December 18 and they placed metal stents saying they are permanent , but at the time they were place his bile ducts looked pretty clear and the stents had good placement. Since Nov 7 he has gained 20 lbs and has absolutely no pain! He is doing great getting his strength back. So now we are at a point that we don’t know what we need to do, we don’t know how much cancer is there. Is there any other treatment they can give him , we really just are lost because the two docs that we started this journey with has kind of washed there hands of the case?? Any help would be greatly appreciated!!! (As of right now bili is 2.9, no jaundice great appetite)
