georgiagurl's presentation is actually quite similar to mine. M-spike .1 to undetectable on SPEP (but always present on SIF). BJ protein in urine. Kidney function normal, PET negative for lesions, cardiac MRI negative for amyloid. But light chains off the charts (ratio 150:1 L:K, free L 1400). Just had my third BMB last month - 5-7% plasma cell, same as other two. My hem/onc fully expected the last two BMBs to show >10% (diagnostic threshold for MM) - he even hand-wrote for me the DVRd first-line regimen, expecting to begin treatment. So I'm still teetering on the treat / no-treat edge It's a complex disease.

And, as they say, diseases don't read medical texts.
