Hi your close to MMR4 your response is great no need for any change. Not everyone gets to undetected but anything under MR4 is indistinguishable to Undetected.

Absolutey zero reason to change unless you have bad side effects. And no doctor should change your meds at that level.


Thank u Al!, i just corrected my resulta in the post. 

mil, it isn't at all unusual for a CML patient to have their BCR-ABL plateau at a low level.  With your next (18 month) test, you will have been plateaued at a very low CML level (under 1.0), for a year.  When a CML patient has either been undetectable, or plateaued at a very low CML level, for a prolonged period of time, a year, or so, they can typically begin gradually reducing their dosage without it having an adverse effect on their CML level.  Their CML level will typically gradually drift lower with time, regardless of dosage.  After your next test, talk to your onc about beginning gradual dosage reduction.  The less TKI we take over the longterm the better off we are likely to be.

Recently had two TFR fail restarts on low dosage:
