I’m concerned about what looks like progression of myeloma. (I realize that many data points need to be factored into any analysis, but I’m here focusing on changes of Kappa & Lambda QNT light chains over the past 3 months (12 weeks), from Aug 8 to Nov 13.) Kappa QNT shows a steady decline from 10.31mg/L to 3.14 which averages a decrease of 7.07 over 3 months (0.59/week) Lambda QNT light chains over the same timeframe increased from 74.45mg/L to 123.29 which is 48.84mg/L in 3 months (12 weeks), which averages 4.07 mg/L rise each week. BUT, the past 5 weeks it has shot up from 85.2 to 123.29 = 7.62mg/L each week—almost double in the past month when compared to the last 3 months. I’m on DKd. My oncologist is at this point suggesting CAR-T the end of January. If the Lambda rate of rise continues at 7.62mg/L per week, by the end of January I calculate it could be approaching 200mg/L. Should I be concerned? Thanks!
