Mailman, it's wonderful to hear from you and to know that you are doing so well post-transplant. I'm sorry about the remaining cancer cells. I somewhat know how you feel...I seem to get past one hurdle and regaining my strength, etc., then here comes another! Right now it's a second incisional hernia that will need repair. Anyway, re: the question about how the chemo would help now: As far as they know, your cancer cells are in the blood stream and not in your liver yet. So it would be a preventative measure. I'm not sure I would go for it, either. As you say, if a tumor recurs, it would likely be in the new liver...though it could reappear in your lungs. When they scan me, it always includes the lungs. I think you are wise to get a second opinion, and Johns Hopkins has a great reputation.
The good news is that they are keeping a close watch on you, so if a cancerous tumor should reappear, they would likely catch it in the early stages. I had a study drug (actually a form of radiation), TheraSphere, prior to surgery, as my tumor was so large and had metastasized to the inferior vena cava. The TheraSphere shrunk the metastasis back into the original tumor and shrunk and killed the original tumor...but the whole lobe was removed as it was in such bad shape, and also as a precautionary measure. The results of this study said that 71% of the participants responded favorably. So I am one of the lucky 71%. When I started treatment, I was facing a death sentence, so I feel VERY fortunate. I never gave up hope, though, and neither should anyone else--until the very end when it becomes obvious there's nothing else to be done.
The parents should feel very proud that their unselfish donation of their son's organ has kept another alive.
Let us know what Johns Hopkins has to say, and continued blessings for you!
Hugs,
Connie
