One Year Later… Alive and Well
Monday, May 31st, 2010It’s hard to believe it has been over a year since I was first diagnosed with chronic myelogenous leukemia (CML). I am alive and well—very well. The levels of leukemia in my blood are falling, and I have more energy now than I’ve had at any other point in the past year. But I’m learning what it means to manage a chronic condition.

The primary test used to measure the level of leukemic cells in my body is referred to as PCR (polymerase chain reaction). As you may recall, my PCR score when I started treatment was 100.0. After three months, my score had dropped nominally to 97.0. But after six months, my score was down to 0.49—a very significant drop. At nine months my score was up to 0.87—my doctor (Dr. Michael Mauro) told me not to worry about it, he considered that a plateau, not a proression of the disease (easy for him to say). Turns out he was right, another four weeks later (on March 1, 2010) it was back down to 0.57. But the problem now was that my liver was in substantial distress—turns out the medication (Gleevec) was causing liver toxicity.
After five stressful weeks off all medication, while my liver healed, I started on Plan B. I’m infinitely grateful that not only does a Plan B exist, but that we also have a Plan C and possibly other plans, all available before the ultimate back-up plan—a bone marrow transplant (which is the only option for patients diagnosed with more advanced forms of this disease). And I’m further fortunate that my brother is a donor match should I need a transplant. But, call me an idealist… I’d prefer not to work my way through these options. I like having them available and not needing to use them. Anyway, I started on Plan B, otherwise known as Tasigna (aka nilotinib), on March 29, 2010.
Tasigna is a second generation version of Gleevec, developed by Novartis (the same manufacturer as Gleevec). It has been used as a second-line therapy for years, and will soon be approved for first-line therapy (meaning it may be used immediately upon diagnosis, rather than just after a patient has developed an intolerance to Gleevec). It has been proven to be as effective, or more effective, than Gleevec.
After being off Gleevec for five weeks, and on Tasigna for four weeks, I went in for my regular PCR test (on April 26, 2010). The results were disconcerting. My PCR levels were back up to an 11.0. A very rapid rise, but again my doctor was reassuring. We repeated the test three weeks later (on May 17, 2010) and the results were much better. It seems the Tasigna is working and my PCR level is now back down to 4.1—trending the right direction again.
We continue to watch my liver function closely (because it is possible for Tasigna to have the same side effect on my liver as Gleevec), with weekly blood tests. My anxiety levels rise and fall with the test results of my liver function, but so far everything is relatively stable.

I’m a fairly linear thinker. I like the notion of diagnosis, treatment and cure—all along a linear path without plateaus, complications and regression. But, I’m slowly (reluctantly) learning what it means to “manage” a chronic disease. And if it can be successfully managed, then who am I to complain or demand more?
Reflecting back on this past year, I’m extraordinarily thankful. Thankful for your thoughts and prayers. Thankful that I have multiple treatment options. Thankful for the talented and caring doctors and pharmacists who provided me with these options and treat me with candor, humor and compassion. Thankful for the relative ease of my treatment (compared to what it could have been with a more aggressive form of CML, or a different form of leukemia). Thankful for my life, and the time to live it with the ones I love. Thankful that my leukemia is being successful managed and justifiably hopeful that I’ll have many, many more years to be thankful.
