Is there a recommended frequency with which one should get PCR testing done after the first year of treatment?
I was diagnosed in April 2011 and have been on 800mg daily of Tasigna. I am on a research protocol with MD Anderson so for the first year I had monthly blood tests and quarterly bone marrow aspirations and PCR tests. At 3 months I had achieved CCyR and have maintained that (all confirmed by the aspiration). In April at the one year mark my PCR was down to 1.31% on MD Anderson scale (at diagnosis it was over 100%). My PCR number has trended down at every test.
Now that I am in my second year of treatment I move to 3 month blood tests and 6 months aspirations. I have my next blood draw in a few weeks and according to the research nurse, she said I wouldn't have a PCR test done...just the CBC and CMP. My next PCR would be in October which would be 6 months since the last one.
What is everyone's thoughts on waiting 6 months for my next PCR? The NCCN guidelines don't really discuss frequency of PCR so I wasn't sure if I should push for the PCR done at 15 months or wait until October.
