Jacqueline,
My husband (40) also had a Klatskin's tumor. He had surgery in October 2004. The surgery went well but unfortunately they didn't get clear margins. He had a combination of chemo and radiation in January hoping to get the margins but it didn't work. A new tumor started growing by February. He just started a new round of chemo in March. What I thought was intersting with your case is that my husband also has an underlying infection that they can't find (presumably from the surgery). Every time they took him off of the antibiotics he would get a fever and end up admitted to the hospital. Because they are trying to fight the tumor they have pretty much given up trying to find the infection for now. He is just going to stay on Cipro indefinitely. I'm sure at some point they will revisit it but I don't know when. He had a white blood cell tagging test to try to find the source of the infection but it was inconclusive. Have your doctors talked about doing radiation or chemo as adjuvunct therapy (therapy to get what cancer cells might be left behind)? I've heard of them doing it in several cases including my husband's. I wouldn't wish the radiation or chemo on anyone but it might be worth discussing with your doctors. Good luck with your fight - I hope you continue to have no recurrence. It is great to hear some good news about this cancer.
