I haven’t blogged since late November, but it’s not because I didn’t want to catch you up on what has happened since then, but rather because I have been physically and mentally unable to do it. Instead, I went ahead with a lymphocyte infusion from a second donation from my donor. The result has been largely unexpected, overwhelming, and quite improbable.
On the other hand, if I didn’t do DLIs, my fate was clear and approaching. Me being me, with a history of phenomenal luck, and after reading the recent journals, I pushed hard to do it. It took some convincing.
There’s no graft-versus-myeloma (GVM) effect without GVHD occurring in less than one hundred days (referred to as “acute” GVHD). After that, if GVHD occurs, it’s called “chronic” and provides little or no benefit. So DLIs, when given, are often given at intervals (of several months or longer) to provoke the necessary acute GVHD response. The average time to ultimate response, if any, seems to be four to five DLIs.
There’s part or me that didn’t want to show you Grade IV GVHD. This is not me, I believe mine was grade III. My skin is red, but returning to normal after exfoliating, my donor must hate callouses, and my GVHD has attacked my liver, skin, and bowels more than anything else.
I calculated the odds from good data for achieving aGVHD on the first shot: less than %5. I expected that there would be no immediate consequences, negative or positive, of the infusion (we were looking for aGVHD to appear perhaps weeks later). In fact, it went down like this: I agreed to proceed on Monday, 28th November; the cells arrived by the next day; on Wednesday they were infused in the afternoon and I went home. By the next day I was admitted to hospital with a horrendous case of GVHD. They doped me with methylprednisolone, to suppress the reactions, which caused serious delirium. Apparently, I was unconscious but active, rolling my eyes around to no purpose, attempting to pull out my picc line (I succeeded on the first one), completely out of it. By that evening I was back in the ICU fighting for my life. I’ll write about that shortly. Of all of four hospitalizations for myeloma, this was the most punishing. Several doctors thought I wouldn’t survive.
|Three Days after DLI|
But I did survive, and after a few days I was back in my regular room, unable to do anything for myself. Two weeks after the infusion, I asked for a test of my light chains: I wanted to know if all of the suffering I had endured did anything to the cancer. A week or so later, the doctor who pioneered the facility brought me the results, but unlike the five lines I usually see, it was a full page of words. With my head full of steroids, which made reading difficult, I tried to understand what the report was saying: I knew the possible danger of reading into the words what I want to them to say, so it took three times through the realize that the report was saying complete remission. No sign of “extra” light chains. Further, every one of the three numbers was in the middle of the normal range. The cancer was gone. My luck still holds: I got the 5% result, and enough GVHD to fight the cancer without yet killing me in the process (at least, not yet).
I was stunned. When the doctor who has directed the Center for more than thirty years leaned over with a flashlight to look in my mouth, I said to him, “Do you mind if I kiss you?” This guy may be in his seventies, and I must admit it was fun to watch him try to react! He’ll never forget me now. When he demurred, I said, “But you did hesitate!”
CR, on the average has just given me another multi-year lease on life without cancer: the present curves suggest five years or more. There is also a non-vanishing possibility that I’ll never see multiple myeloma again.
Last Wednesday I spent hours in the hospital, as I have to do once a week. When they wheeled me into Hematology on my wheelchair, for some reason I was left in an open space for a time. During that time all but one of the doctors who had treated me walked by and said hello (the other one I saw earlier). I’m guessing it was a shift change, but it was then I began to realize that my survival is a huge triumph for the doctors and nurses, too.
Next post will tell you about what the DLI did to me and is continuing to me. I thought that after the allo in 2010, nothing could possibly be as difficult from which to recover. I was wrong.
