#79. My Numbers!

This is the post I’ve been looking forward to writing for some time now. It documents a radical improvement in my myeloma situation. Now, if only I could find a way to rapidly decrease the problems and pain I get from arthritis and degenerative disk syndrome, I would almost be back to a normal life. Of course, I keep forgetting that I’m 74 years old and that I’ll never be able to do the things now that I used to do just ten years ago. But enough grousing about my limitations, it’s time to focus on some recent victories that have everything to do with my numbers.

For me, the one thing that came along with the diagnosis of multiple myeloma or bone marrow cancer was (and is) an obsession and fascination with my numbers. I wrote about this earlier in a blog post on December 17th, 2019 (https://rogerjgalbert.com/2019/12/17/access-to-medical-records/). Now is a good time to revisit my obsession with my numbers because I’ve recently had some pretty spectacular changes in some of my critical numbers. I concur with Paul Kleutghen when he writes:”We (patients and caregivers) have all become so attuned to focusing on numbers that any excursion out of the “normal” causes worries and sleepless nights.”* I generally don’t lose sleep over anything, but, like Kleutghen, I am focussed on my numbers, and I get pretty upset if my numbers are going in the wrong direction or stand outside of the reference numbers.** Of course it’s an entirely different story when my numbers go in the right direction. Numbers are important to me and you’ll see why in this post.

My numbers refers to the lab results I get from frequent visits to the Vancouver Island Heath Authority (VIHA) lab in Courtenay, or to the hospital lab. As a regular thing I get checks of my blood, my white blood cells, red blood cells, monocytes, hemoglobin, neutrophils, eosinophils, basophils, etcetera. I also get regular tests of my kidney function by analysis of creatinine in my blood serum. (I have access to all my lab results through an online VIHA service called MyHealth.). By the way, a really good source of information about reading our lab results can be found here: http://media.myelomacentral.com/wp-content/uploads/UnderstandingYourLabResults.pdf.

Once a month or so I get tested for more myeloma specific indicators in my blood serum. These are paraproteins and free light chains, both kappa and lambda. Our blood has both Free Light Chains and Heavy Chains. These are simply descriptions of the organization of proteins in our blood serum. Without getting into too much technical detail it’s important to note that some myeloma patients are kappa free light chain myeloma patients and some are lambda free light chain myeloma patients. I’m a lambda kind of guy.

So, I went on a new chemo regimen in January. It’s composed of dexamethasone, a glucocorticoid, lenalidomide, a chemo drug (they’re not sure how it works) and Daratumumab, a monoclonal antibody. If your eyes haven’t glassed over yet from all the technical jargon I invite you to have a look at the table below I got from MyHealth. It refers to my Lambda Free Light Chains from June, 2020 to February 26th, 2021. It’s a very informative table. The red numbers highlight times when the lab results indicated that I had lambda free light chains higher than the reference range, which is conveniently given on the right in the table. You can see that from September 30th, 2020 until January 27th, 2021 that the myeloma was getting more active again in my blood, a conclusion supported by the redness of the numbers therein. Not only that, but you can see that the amount of free light chains in my blood was increasing rapidly during that time from 44.2 milligrams per litre of blood on September 30th 2020 to 201 milligrams per litre of blood on January 27, 2021, but in fact had been increasing from June 30, 2020. That was a very worrying trend because the more free light chains in my blood the sicker I get.

Then I started the new course of chemotherapy and the lambda free light chains in my blood went from 201 to 11.7 mg/l a number well within the reference range. That”s why I got so excited when I saw the ‘normal’ 11.7 mg/L on February 26th, just a few days ago. In my discussion with my oncologist in Victoria, he said that we shouldn’t expect to see any positive results for two to three months and here I went from a high of 201 to 11.7 in a month! Now, that is cause for celebration. It means that the Daratumumab is my buddy and is working better than expected. Hallelujah!

**reference numbers are a range of numbers within which numbers should fit in a ‘normal’ person. Reference numbers are where the majority of people would fit in terms of their standing on any particular measure. It’s a range because there is understandable variation from patient to patient. For example for Kappa Free Light Chains the reference range is 3.30 – 19.40 mg/L.
