Six months ago (Oct 2018) I was diagnosed with accelerated CML (33k wbc, 13% blasts, BCR/ABL 44%). Fish showed positive for t(9;22).
(Unfortunately, and probably not coincidentally, at the same time I had pericarditis with tamponade, requiring emergency surgery and a week in the hosptial. This was followed by several months on amiodorone, colchsine, dialtizem, and prednisone. I do strongly feel these issues and medications complicated my subsequent CML treatment.)
Once released for the pericarditis, I went on 140mg of Sprycel for about 3.5 weeks (10/9-11/1) until my blood counts bottomed out. First the platelets, then the neutrophils.
So for 4 weeks I was off Sprycel. Then for 1 week (11/30-12/6) I went back on at a lower dose, 100mg, but quickly saw low blood counts and stopped right away.
When my numbers hadn't come back up soon enough after 2.5 weeks, my doctor took another biopsy. The best news was that blasts were now only 1%. But it also revealed a new metaphase t(8;21). Concerned about the meaning of this and next steps, he sent me to see a colleague in the same organization. This doctor said the new metaphase likely resulted from being off treatment for so long. (Oh, he also ordered a fish test, which was negative for AML... huge relief.) But based on the clonal evolution, he was rightly concerned about letting me reach acute/blast phase.
So on 1/7 I was basically placed on a 3 month ultimatum. Either fix this with chemo or do a bone marrow transplant. I was entered into their bone marrow transplant program and they already found 4 donors who are 10/10 matches--a welcome bit of good luck, even though I'd rather avoid needing their help.
The chosen path was a lower dose of Sprycel and hope that things improved while my body tolerated the chemo. (If things got too low, he said they'll give me nupegen. Potentially I'd switch to Bosutinib.)
Accordingly, I restarted Sprycel on 1/7. The dose was 70mg every other day since I had those pills on hand. After 2 weeks, it went down to 50mg every other day, which is the dose I'm on right now.
Unfortunately, today my blood counts are crazy low: neutrophils 0.15 x10(9)/L; platelets 29 x10(9)/L. Despite this, my team still want to continue at 50mg every other day, obviously in hopes of avoiding any leukemic setback that would force the bone marrow transplant.
For reasons that became obvious to me with more information, I hope to manage the CML with chemo. This motivates me to stay on Sprycel despite the terrible cell counts. But I'm also worried about the cell counts, and worried about taking nupegen, and worried about anything that doesn't help.
Oh, I should give you my BCR/ABL counts: 9/24--48% (before Sprycel); 10/5--44% (still before Sprycel); 1/7--40% (11 weeks after last Sprycel, which had totalled only about 4.5 weeks); 1/10--50% (after a couple of days at 70mg every other day); 2/8--27% (after about 5.5 weeks on 70mg and then 50 mg every other day).
Right now I mostly wonder how to approach my current low cell counts against the strong pressure to keep fighting my leukemia, considering my clonal evolution. I don't want to let up on treatment but I don't like how low those cell counts are. And I hope to avoid a BMT. What to do?
Thanks so much to this amazing community, and thanks for any thoughts.
