Hi John,

I'm currently on 400mg of Gleevec and doing well.  I started on 800mg 
but had problems with crashing counts and a huge gout attack 
(probably triggered by the high tumor load and edema).  I'm likely at 
CCR or better, but I won't know for sure until my next BMB or FISH. I 
could probably increase Gleevec to 600mg, but so far I'm happy with 
my response at 400mg.

I've written a bit about the high dose controversy in newly 
diagnosed, but I'll recap it again here.  There is an ongoing 
controversy amongst Heme/Oncs regarding the starting dose for newly 
diagnosed.  The controversy started when Dr. Kantarjian published an 
article in Blood early last year that showed improved results with 
treating patients at 800mg of Gleevec vis-a-vis historical norms at 
400mgs.  His results showed faster and improved responses (more 
patients achieving higher log reductions more quickly) as well as a 
lower frequency of clonal evolution that might lead to Gleevec 
resistance.  Similar data has been reported by other researchers 
recently at ASH (the annual American Society of Hematologists 
conference).

What makes Dr. Kantarjian's data controversial however is that newly 
diagnosed patients fare better on Gleevec than the historical norm of 
patients which included late chronic phase patients (patients who are 
not newly diagnosed) who were previously treated with interferon.  
This is another competing explanation for the improved responses seen 
by Dr. Kantarjian.  There are two fully randomized trials currently 
underway that should resolve this controversy soon.  As I've 
mentioned before, it wouldn't surprise me that 400mg is shown to be 
slightly suboptimal for some people and that a higher dose like 500 
or 600mg ends up striking the best balance between improved response 
and side effects.  I don't know if the randomized trials will include 
600mg results.  If not, it wouldn't surprise me if the controversy 
will shift to 600mg vs 800mg in newly diagnosed.

After being on Gleevec for going on 7 months now and having seen the 
side effects firsthand, I personally am not a big fan of 800mg unless 
it's prescribed to overcome resistance.  If you do go this route make 
sure your Heme/Onc monitors you closely for low blood counts.  My 
platelets went quickly from 750,000 to 47,000 for example (and would 
likely have gone lower if I didn't go down to 400mg).  Even Dr. 
Kantarjian's article showed that 50% of newly diagnosed patients 
treated at 800mg had Thrombocytopenia (low platelets).  Low counts 
can be treated, but the point is that the Hematologist has to be on 
the ball and anticipate these problems if they go the high dose route.

I was impressed that your doctors hospitalized you and you were given 
daily leukapheresis to debulk your cell counts.  My debulking 
treatment was solely at home from Hydrea and it took about 3 weeks to 
get my counts under control before starting Gleevec.  This process is 
tough on the body.  I drank over a gallon of fluids a day for example 
and even then had a severe gout attack.  It sounds as though they 
were able to get you on Gleevec right away which is a good thing.

Did you notice a difference in how you felt after the debulking?  I 
went from being hot all the time and feeling bloated from my spleen 
to feeling skinny and cold all the time.  I liked being skinny, but 
it didn't last long as I quickly gained about 20 lbs after starting 
Gleevec.  

I recently posted about how I came to be diagnosed and you can find 
it here (http://health.groups.yahoo.com/group/CML/message/90916).  I 
was dx'ed with "only" 1.5% blasts.  As I mentioned before (and 
reinforced with the info about your spleen and blasts) that you're 
likely in a higher Sokal risk group for newly diagnosed chronic phase 
patients so it wouldn't surprise me if you end up on a higher dose of 
Gleevec at least to start and are tested more frequently.  

I was also told that I was lucky that I didn't suffer a heart attack 
or stroke with my counts.  I did have noticeable bruising and a 
bloody nose that was a problem on and off for over a week.  Luckily 
no vision problems.  If you're down to 60% PH+ from your BMB (I think 
you meant to say ph+ rather than blasts) you're showing a great 
initial response to Gleevec.  Some doctors (including Dr. Timothy 
Hughes) feel that getting a major cytogenetic response at 3 months is 
one of the best prognosticators and it sounds like you are on your 
way.

I hope you do well on Gleevec my friend and that your vision returns 
to normal.  Please keep in touch and keep us apprised of your 
recovery. 

All the best,
Mark

and a half.  After a myriad of tests, I got daily leukapheresis 
treatments along with 5 grams of hydrea per day.  After my fourth 
treatment, my WBC was down in the 20's and then it only took me a few 
weeks to get it down into the 6-7 range. so I think I was pretty 
lucky.

measurement, and at dx it was 21 CM.  The Dr notes from the CT scan 
showed a lot more interest in a couple hemorrhages in my posterior 
temporal lobe.  I'm really lucky to be here, whew!   All of my early 
medical records have Acute Leukemia all over them, but the final 
diagnosis was CML, Chronic Phase w/ 5% blasts.  A single clone was 
identified with the PH, 9,22 translocation and mild reticulin 
fibrosis.

well for you.  I assume you are on Gleevec too?  Has your Dr. bumped 
you up above 400mg?  My doc is against it, so I'm getting a second 
opinion tomorrow.
