Vidaza, Cycle 3

Beth immediately responded to the Vidaza today, in a negative way. After two transfusions in recent weeks, she has been feeling about as well as she has felt in months, over the last few days. However, the Vidaza treatment reminds her that it really is a kind of “chemotherapy,” and the “cytotoxic” effect just knocks her on her butt. Back again are the diarrhea and the body aches and the desire to sleep all the time.

Yet the other thing that Vidaza does is to “change the genes” in the blood cells. Enables the blasts — “baby” undifferentiated blood cells — to differentiate and become normal healthy cells.

There are three major cell lines in your blood: red (hemoglobin), white, and platelets. Beth’s red blood cells are consistently low and they don’t seem to be responding. White counts and platelet counts are low but holding steady. This is one of the good effects of the Vidaza. Neutrophils (white cells) are low but holding steady. Monocytes (another white cell) are high. That’s one of the reasons why this is “chronic myelomonocytic leukemia” (CMML).

The intention is to have her bone marrow in as good a shape as possible in preparation for the transplant. Dr. Jalil said yesterday he wishes her hemoglobin would have shown some signs of recovery by now. But, he says, “after only two treatments, things look good.” If her hemoglobin still was not responding after three, four, five treatments, “we would be a little worried”.

What if it doesn’t respond this time? He says they’ll still go ahead with the transplant. My sense is that it’s the only real option. If she were 75 years old, they’d continue with the Vidaza and blood transfusions so long as they made her comfortable. But the prognosis for this disease is not a good one. They’ll want to do the transplant, to wipe the slate clean anyway.

We’ll find out more about that at the intake meeting today.
