Hi All,

Here's a quick background and info my new experiment.

  • I was dx in Sept. 2008 and started 400mg of G right from the start
  • Within 18 months I was PCRu
  • I've now been PCRu for 36 months and my side effects have been relatively low
  • About a year ago I approached my Onc with the idea that after three years PCRu I would like to reduce my dosage to 200mg
  • My Onc wasn't/isn't a huge fan of the idea, but last week after my PCR test again came back negative she agreed to reduce my dosage to 200mg
  • I had been getting PCR tests every six months but with the new reduction I'm going back to testing PCR every three months
  • All other blood counts have been good the whole time

My thought process was; why over medicate if there's no need to and why put extra strain on liver/kidneys if not necessary.  Lastly, even though my side effects were low, why not have even less side effects if I can maintain PCRu on 200mg.

I'll let you guys know how it goes and if I lose my PCRu response I'll jump back to 400mg.

Hi John,

Please do continue to update your status and good luck to you.  I am in a very similar situation to you (PCRU in 6 months, have maintained for 3+ years) and I am looking to back off dosage.  I have recently lost a bunch of weight and Gleevec side effects are starting to become more of a problem (specifically eyesight).

I would love to take a Gleevecation.

Sounds reasonable.  I have continued to be PCRU on 200mg Gleevec for the past 4 years after reducing from 400mg after 3 years PCRU.

Hi All,

Quick update...

I just had my second PCR test since reducing to 200mg and I'm still PCRU 

All other blood counts are normal and I feel great with almost zero side effects!  My Onc said she's not going to get to excited until I get a year under the belt but so far so good.
