Hi Missm,
I’m also in the “lambda light chain club” and your initial diagnosis reminds me very much of how my cancer was picked up!
My kidney function was down to 12% on hospital admission via A&E, but after five chemo cycles I was in full remission and my kidney function was back to normal. That is where we differ, with regards to kidney function.
So when I went in for my SCT I was feeling pretty much ok, but that quickly changed after the malfalin, and the next 10 or so days was spent lying on my hospital bed hoping I would feel better the next day.
But I did get better, and was out of hospital after 2 weeks, less my hair and a little weight. It took a few more months to fully recover.
As to whether you should go ahead or not due to your reduced kidney function, I think if I was in your situation I would go along with what the experts say. This is after all what they do every day. Any treatment to reduce your paraprotein levels is going to improve your kidneys long term efficiency.
Best wishes,
Derek
