  1. SCT stem cell transplantation, dFLC difference between involved and uninvolved free light chains.
  2. aOf those without a hematologic complete response, patients may be included in 0 or ≥1 category depending on free light chain results.
  3. bCardiac staging data unavailable in 121 patients of total cohort.
  4. cRenal staging data unavailable in 3 patients of total cohort.
  5. ddFLC calculations were performed using a value of 0 for all FLC levels reported as less than measurable in 26 patients.
