Ive posted our story in other threads, but here it is in a nutshell: Wilbur has chronic B-cell lymphocytic leukaemia. He is 6 1/2. To complicate things he also has hydrocephalus. He is on another med for the hydrocephalus but prednisone for both the cancer and the hydrocephalus, so he will always need it.
For his cancer, we are not treating with intensive radiation or IV chemotherapy. We are giving a combination of chlorambucil (the chemo drug) and prednisone, bothe of these I give at home and they are both pills. The chlorambucil has to be handled with gloves. Initially he was on high doses of both the chlorambucil and the prednisone, and that was hard to see him go through that. And it wasn't the chlorambucil, it was the prednisone side effects (thrust, urniation, super bloating, severe discomfort). Thankfully that has been tapered down to less than 5mg per day.
Specifically, the chlorambucil showed zero side effects that I could see. He will remain on one pill a day for the rest of his life, and I am fine with that. HIs leukaemia is in complete remission. We are 3 months since diagnosis. I have bloodwork done every month-6 weeks. He is doing awesome, you would never even know he is sick. I know that this won't last forever, but for right now he is doing well and is essentially himself. A greater concern are the prednisone side effects, but with the lower dose he is doing much better and his liver is doing pretty good too.
There is hope to have a pretty good quality of life... once Wilbur starts to decline, I will know it is time and that I did everything I could to keep him happy and comfortable for as long as I could.
Fingers crossed for you, and best wishes that Mack is feeling ok.
