My recent post on dealing with change and adversity was inspired in no small part by a change I am facing in my own life, one rife with uncertainty and heavy with anticipation. The last CT scan I had showed that my primary tumor, the one by which we gauge progression or lack thereof, was still within the technical boundaries of business as usual. That is to say, its lateral dimensions had not changed significantly since the previous scan, and overall had not grown enough over the similar measurements from a year or two years ago to precipitate anxiety. But CT scans are, for lack of a better term, a bit fuzzy. The images are fairly clear, but the data is difficult to measure with absolute precision.
Because CT scans are essentially three-dimensional, but are viewed on two-dimensional screens, comparisons between scans are inherently imprecise. The angle of a subject’s body, how inflated the lungs were, the position of the subject within the imagining chamber, all figure into subtle differences between the final scans. On top of that, because the images are basically multitudes of cross-sectional snapshots, a comparison must be made by selecting the closest approximation to the “same” image between scans from different times. I’ve looked at lots of these — in fact, I keep digital copies of all my scans for reference or posterity — and I’ve used the tools to line up and measure my tumor as best I can.
And in two dimensions, at the standard viewing cross-sectional approximation, my mass looks very similar from scan to scan, every three or so months since this process began. My chemotherapy was clearly doing what it was intended to do, which was to prevent progression of the disease. Progression is generally defined in terms of the length of the tumor, but we all know that tumors are bundles of cells that grow and change along more than just one axis.
I was never under any illusion that the chemo would cure me — there is no official cure for Stage 4 Lung Cancer. Any time that the chemotherapy could afford me by maintaining stasis has been considered a luxury and at over two and a half years on this particular regimen, I have been the longest continuous success case that many on my medical team have known. So the next time I see most of them will be a special, bitter-sweet occasion.
Because the time for change has come. Continue reading Chemo and I Had a Pretty Good Run
