7/27/12 Diagnosed with MGUS/smoldering myeloma. There was no intervention at this time.
In about October/November 2012 the diagnosis was reported as smoldering myeloma,.
Answer:
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Indolent myeloma [9732/3] and smoldering myeloma [9732/2] are reportable terms synonymous with plasma cell myeloma. Monoclonal gammopathy of undetermined significance (MGUS) [9765/1] is not reportable.
