Janita, allow me to re-ask part of David's question: What dosage of Nilotinib are you on?
You may be able to reduce your dosage to help reduce the side-effects you are experiencing. The standard starting dose is 600mg, (2 X 300). A few reduce to 300mg early in treatment due to side-effects.
Age seems to play a part in the CML scenario; younger person's bodies seem to be more tolerant of the TKIs; the average age at diagnosis is 64; younger CML patients seem to have a more difficult time maintaining TFR although there isn't much in the way of compiled data. Seems they forgot to add that to the stats during the trials; there's only one trial that included that statistic:
The ISAV (for Imatinib Suspension And Validation) study http://bit.ly/1UWAZ78
was conducted in five countries (including Canada) and used a new digital PCR test which is reportedly 100-fold more sensitive than conventional PCR testing (Mori and colleagues. ASH 2014; abstract 813).
The 112 people enrolled in the study were required to be in CMR for at least 18 months. The median time on imatinib (Gleevec) was 8-9 years, and the median duration of CMR was 26 months. In the first 16 months off treatment, 43.5% of people relapsed, typically within the first nine months.
All of those who relapsed were able to regain MMR or CMR with two months of re-starting treatment.
In this study, the amount of time on Gleevec didn't have an impact on the risk of relapse.
However, a person's age was inversely related to the risk of relapse. Relapses occurred in 90% of people aged 45 years or younger, compared to 37.5% in those aged 45-64, and 27.5% in those aged 65 years or older.
I'm liking the odds.
