Best guess is that I have no surviving B-cells. IgM and IgA are unmeasurable, as are free light chains. IgG trickles down, which is still consistent with zero production and a longish half-life. PETT can’t distinguish between tumor activity and anti-tumor activity. I’m slowly getting used to optimism.

Biggest problem is that I’m pancytopenic and no doubt immunocompromised. Nobody can predict how long it will be before I can face a crowded room or airplane. We’re monitoring, taking Neupogen about weekly. Platelet transfusion to get my line out on 10/25, but the counts have started rising again this week.
