Hairy Cell Leukemia
When I was diagnosed in November 1999 with a rare leukemia called Hairy Cell Leukemia (HCL), I never imagined how many times I would cross paths with this disease. I was told by my local oncologist that HCL was very treatable and rather slow as cancers go. Also, most people get complete remission and the leukemia often doesn’t return for at least 10-15 years. Hairy Cell Leukemia certainly sounded better than other leukemias and cancers I had heard about.
So in December 1999, I was given the “gold standard” for Hairy Cell Leukemia treatment. Back then the treatment was seven consecutive days of 2-CdA (Cladribin). I had no real side effects from the chemo and didn’t miss any work.
But my Hairy Cell Leukemia came back again and again. I averaged only 2-3 years between occurrences. Side effects started to become more numerous and troublesome.
I switched to a nationally recognized oncologist/researcher at a leading hospital who is very familiar with HCL. He told me that I had one of the worst remission histories that he’d ever seen or heard of.
In late 2013, I was encouraged by my oncologist to join a Phase II clinical trial for Vemurafenib, a targeted therapy drug, for cancer patients with a BRAF mutation. HCL patients typically have this mutation and I did too.
But after 3 months of taking this drug in early 2014, for my 6th occurrence of Hairy Cell Leukemia, I only received a partial response. I endured over 30 side effects including a lot of skin cancers and abscesses. In my opinion, clinical trials are oversold and make sense only if you really have no other treatment options. I realized later that wasn't my situation.
I found Dr. Nagourney and Rational Therapeutics while searching the Internet late summer 2014 when I was looking up treatments for Stage 4 pancreatic cancer for one of my family members. The idea of testing your own cancer cells and coming up with drug choices which would be most effective with my stubborn cancer seemed amazing and sensible.
I finally realized that no matter who my oncologist was, they were all just guessing on what might work for me. I was tired of all these guesses.
Meeting with Dr. Nagourney was different than other oncologists I had worked with. He took his time and spent over one hour with me. I learned more about possible treatment options for my cancer than I had ever heard of working with other oncologists over the years. I became optimistic!
Well, I didn’t have to wait long for my leukemia to come rushing back. In November 2015, I found my chance to have Dr. Nagourney test my leukemia cells. I underwent my 9th lifetime bone marrow biopsy and had a sample sent to Rational Therapeutics. Dr. Nagourney’s staff performed their EVA-PCD assay (functional profiling test) on the HCL cells found in my bone marrow aspirate. My marrow was 95% leukemic and the assay came back with some informative results.
Based on the assay results, I was put on a 2-drug combo: my old friend and “gold standard” for HCL patients 2-CdA, and Rituxan. I had easily tolerated 2-CdA several times in the past but the drug never gave me much of a remission. Rituxan gave me a very adverse reaction back in 2006 which sent me to the hospital. In December 2015, my blood counts were pretty bad. The main symptom for Hairy Cell Leukemia is low blood counts (pancytopenic).
I took the 2-CdA easily and my blood counts recovered somewhat. By slowing down the IV rate I got the 1st of 8 scheduled weekly doses of Rituxan (500 cc) into my system. However, we had to hold off on the 2nd dose for awhile because I ended up in the hospital with a series of bad infections.
When we did go back to the 2nd dose of Rituxan, we tried and tried and my body just couldn’t tolerate it any more. I encountered many, many side effects. This disappointed me since the protocol for Rituxan is eight doses – once a week. And I couldn’t even tolerate two doses!
We then planned to start treatment with a 3rd drug so a bone marrow biopsy was done to see how many leukemia cells were still left in my marrow. To everyone’s amazement, the pathology report said that I had only 0.02% Hairy cells left in my marrow!
I had achieved my first Complete Response out of seven tries and in 16 years! And this with 2-CdA which had not really worked in the past plus only one dose of Rituxan. This confirmed my belief that if I could just get my cancer tested I could get the right Hairy Cell Leukemia treatment for me.
I had a lot of people praying for me and I credit God, Dr. Nagourney, his partner and staff in helping me get rid of this darn disease, at least for now. It still hasn’t sunk in that my leukemia is essentially gone and I have a chance at my first long remission!
Since late last year, I have been telling whoever would listen that everyone should have their cancer cells tested BEFORE getting any drug treatment and now I can say I’ve "put my marrow where my mouth is!" Thank God I discovered Rational Therapeutics and Dr. Nagourney and I look forward to NOT worrying about any leukemia coming back for a long time!
