Sandy,

My son Kevin is six and was diagnosed with CML in March.  After six
months on Gleevec (9/29/2008) he has achieved Complete Cytogenetic
Response (CCR) and his PCR is 0.022.  We're sticking with Gleevec.

You don't happen to live on Long Island, do you?  Your story sounds
very similar to ours: we were told Kevin would have a BMT from his
9/10 sibling match, possibly in July-September, and in the end he
would be just fine.  Our second opinion said no way, stay on Gleevec.
We know a bio-chem professor whose PhD classmates now work in cancer
centers and top hospitals around the country.  She did an informal
survey and found the medical community is disturbingly split on the
treatment plan for pediatrics.  After visiting the Seattle Cancer
Center Alliance, who have done the most BMTs in the country (Fred
Hutchinson Cancer Center is now part of it), and Dr. Druker in Oregon,
we've decided to stay on Gleevec unless Gleevec and related drugs stop
working, or there's a cure.  Let's hope and pray for that!

My wife Julie recently posted more details about all of this on the
"Child CML Talk" page:

There are no simple rules for any of this, so I can't speak to your
son's case.  Plus I'm not a doctor, and no doctor we spoke to would
make recommendations without first examining our son.  In Kevin's
case, a top hospital said they would do a BMT if there was a 10/10
match.  Since there is none, they recommend staying on Gleevec and
doing a donor search every 2-3 years (I think).  Dr. Druker strongly
recommends staying on Gleevec for many reasons.

The fact that we're sticking with Gleevec for our six year old says it
all.

The most important piece of advice I can give you is to get to a
doctor who believes in Gleevec, and knows how to monitor CML, and get
on the correct Gleevec dosage.  I've read many stories about people
coming off Gleevec for a short period of time because of side effects,
then going back on it.  Some have reduced their dosage.  Others have
increased it for various reasons.  In our case, Kevin was on too low a
dose for months.  There is something they call a "trough level test"
that measures the amount of Gleevec in the blood 24 hours after the
last dose.  Kevin was 30% lower than recommended.  We increased his
dose, repeated the test weeks later, and now it's at the right level.

Our first doctor was planning for a BMT and felt the trough level test
was unimportant.  We strongly disagreed with both of those ideas.  We
used to do all the research and tell our doctor what we found, and he
would need to be convinced to make changes or perform tests.  Now
we're with a doctor who believes Gleevec is the way to go.  He knows
more than we do about treatment with Gleevec, which is a nice change.

If you decide to stay with Gleevec, make sure you have the right
doctor.

I know how confused and overwhelmed we were (are?).  It's a little
better now.  We're seven months into this.  If you'd like to speak
with my wife or me, let me know.

Here are some links I like to understand how Gleevec works, and a
transcript where Dr. Druker explains some stats about Gleevec and
(low) relapse rates:

Dr. Druker lead the creation of Gleevec and spoke on the TV telethon
"Stand Up to Cancer" in early September 2008:

Technical 1 minute explanation of Gleevec:

24 seconds with no sound.  BCR-ABL is the mutation that makes a white
blood cell a CML cell.  ATP is key to the energy cycle of the cell,
and when the substrate detaches it enables cell growth and division.
Gleevec blocks that process:

Really good visual with an explanation in a language from another
galaxy with some words that you could swear were English:

This transcript, 22 pages, is from a telephone education program of
the LLS, with Dr. Druker (there's an MP3 audio as well).  Dr. Druker
explains the data available on Gleevec.  I have no references to put
here, but I believe the data on BMT are more risky than Gleevec:
