Is this possible?
The test was done within the 48 tob72 hour window.
Diagnosed June 2014. WBC 34.6 and Platelets 710 at diagnosis. Bone Marrow Biopsy pre-op diagnosis: Leukocytosis. Post-op diagnosis: the same, Leukocytosis. No increase in blasts <1%. Quantitative BCR/ABL testing and formal chromosome analyses confirmed CML diagnosis.<p>Supplemental Report: Abnormal BCR/ABL1 FISH result t(9;22). Molecular test for BCR/ABL1 fusion transcript by RT-PCR positive for BCR/ABL1 transcripts, b3a2 at 133.561% and b2a2 at 0.001% and ela2 at 0.001%. Followup monitoring showed negative for ela2. BCRABL1 was 148.007 at diagnosis. Started Sprycel 100 mgm and blood work was normal at 3 weeks. MMR at 3 months: 10/4/14 was 0.106.

I was diagnosed June 2014. My Pcr tests have gone well. In 3 months, 0.106. The rest of the numbers are 0.044, 0.066, 0.138, 0.135. All are IS.
My previous reading 3 months ago was 0.0092
Yes Kali, you have apparently reached undetectable. Congratulations! ... wishing you continued good luck.
For the benefit of yourself and others please add your CML history into your Signature
02/2010 Gleevec 400mg
2011 Two weakly positives, PCRU, weakly positive
2012 PCRU, PCRU, PCRU, PCRU
2013 PCRU, PCRU, PCRU, weakly positive
2014 PCRU, PCRU, PCRU, PCRU (12/07 began dose reduction w/each continuing PCRU)
2015 300, 250, 200, 150
2016 100, 50/100, 100, 10/17 TFR
2017 01/17 TFR, 04/18 TFR, 07/18 TFR 0.0012, 08/29 TFR 0.001, 10/17 TFR 0.000
2018 01/16 TFR 0.0004 ... next quarterly PCR 04/17
At the earliest opportunity, and whenever possible, lower your TKI dosage; TKIs are toxic drugs and the less we take longterm the better off we are going to be ... this is especially true for older adults.
In hindsight I should have started my dosage reduction two years earlier; it might have helped minimize some of the longterm cumulative toxic effects of TKIs that I am beset with.
longterm side-effects Peripheral Artery Disease - legs (it's a bitch); continuing shoulder problems, right elbow inflammation. GFR and creatinine vastly improved after stopping Gleevec.
Cumulative Gleevec dosage estimated at 830 grams
Taking Gleevec 400mg an hour after my largest meal of the day helped eliminate the nausea that Gleevec is notorious for.

Congrats, Kali. I'll be glad when researchers figure out why some reach PCRU earlier than others. When this happens, maybe an even more tailored treatment can be developed for patients. I've reached PCRU twice within three months (took a break for a BMB), but am reluctant to consider myself any more out of the woods than the turtles. I really think the turtles should not beat themselves up about a slower response. Does this mean I'm a fox (as in quick as a...) in the CML world? If so, I'm glad I can be one somewhere.

My doctor is willing to entertain cessation but not dose reduction if there is a time in the far future that I become a candidate to do that.
His concern with dose reduction is that the stem cells will find a way to outsmart the drug and ramp up again.

Your Onc is out of date on the dose reduction issue. That story never made any sense, but has been abandoned by almost all Oncs who know what they are doing. I would stay at full dose for another year and then look at dose reduction. PCRU is not an endpoint, but rather a milestone along the way to "near zero".
You have done very well.

He is so much more knowledgeable than the onc I had.
If I stay PCRU I will do what u suggest in a year and revisit the idea. Perhaps even get a second opinion from a CML specialist at that point.
One step at a time.Correct?

Kali,
Many of us are on reduced dosage due to side effects. I've been on 50mg. of Sprycel since 2012 due to pleural effusion. If what your onc said were true I'd most likely be in trouble by now. My rule of thumb is the least amount of drug necessary to keep CML at bay.

I have a few more questions on this topic. Sorry it has taken me awhile to get back. I have been extremely busy and don't know is I am coming or going sometimes with the busyness!!
The Lab my onc uses is ARUP. Is that a good one?
The reason I ask is because since I came to him in October here is how the results go with timing:
10/7/2015 qualitative: Blood Collected on 10/7 at 3:45 pm and Resulted on 10/13 at 3:26 pm. Detected
10/7/2015 quantitative: Blood Collected on 10/7 at 3:45 pm and Resulted on 10/12 at 5:47 pm. Nothing detected The lab said the difference was likely due to test sensitivity.
I had my once redo the test:
10/20/2015 qualitative: Blood Collected on 10/20 at 11:47 am and Resulted on 10/23 at 3:47 pm. Detected.
10/20/2015 quantitative: Blood Collected on 10/20 at 11:47 am and Resulted on 10/25 at 10:15 pm. RTqPCR 0.0126%
1/4/2016 qualitative: Blood Collected on 1/4 at 11:20 am and Resulted on 1/7 at 7:19 pm. Detected
1/4/2016 quantitive: Blood Collected on 1/4 at 11:20 am and Resulted on 1/10 at 5:34 pm. RTqPCR 0.0092%
4/11/2016 qualitative:Blood Collected on 4/11 at 2:05 pm and Resulted on 4/15 at 6:31 pm. No evidence of major p210 type or minor p190 type
My question is if these tests are happening timely. When I started going to this once in Oct. 2015, my readings from the previous one were 0.1
I come up on my 2 year anniversary of diagnosis at the end of June.
I asked my current one to check on accuracy of my tests and communicated with the pathologist/hematologist at our hospital who looked everything over. He said they are fine, but ARUP is only doing BCR?ABL qualitative and reflex to quantitive.
He also said they usually send CML patients blood to Clarinet for P210 quantitive and FISH for BCR/ABL
I am totally confused. Is ARUP doing my blood work correctly or is Clarient doing this correctly?
I come up in a couple of weeks for my next visit and want to get all of this straightened out,
I love the idea about reduction of meds in another year if may numbers stay undetected, but I want to be confident in my Lab work before considering this idea.
Is there something I need to ask my current onc about the lab work to ensure it is at the right lab and being done correctly and timely?Or is this current path with ARUP going fine?
Please advise as this is frustrating, but maybe I am the one lacking understanding on this matter

Please excuse the misspelled words on the previous post. I am trying to type this in a hurry
I forgot to mention that the pathologist did say the very first test with ARUP was possibly not as accurate due to diminished sample.
But, he said all the other ones are fine.
But, if Clarinet just does qualitative and FISH, it doesn't seem that will meet my needs at this point with where I am at with numbers. Correct?

ARUP is a major lab and a good one. Plus, with that many tests they would very likely be accurate. The trends also match. Qualitative (Qual) PCR is more sensitive than quantitative (Quant) so they often report positive longer than Quant PCRs. Your Quals were "detected" until the last one which was "undetected". The Quants are flatlined at near -4.5 to -5 log which should report as undetected in most labs.
All is great. PCRU.
