Question:
Discussion:
Multiple myeloma was diagnosed more than 5 years prior to admission. The patient underwent multimodality treatment.
Currently, the patient suffered a fracture. The pathology report diagnosis was "plasmacytoma." The discharge summary states, "multiple myeloma advanced with multiple lytic lesions".
Does this scenario represent a single primary dating back to the original diagnosis? Or does the diagnosis of plasmacytoma on the recent biopsy indicate a new primary because it was originally diagnosed as acute and reverts to a chronic neoplasm after treatment more than 21 days later?
Answer:
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Per the Abstractor Notes section, this case represents a single primary. Histology is coded to 9732/2 [multiple myeloma], which is now advanced.
Review the Abstractor Notes section in the Heme DB for multiple myeloma. It states that in multiple myeloma there is generalize bone marrow involvement. It further states that lytic bone lesions and bone tumor masses of plasma cells (plasmacytomas) are signs of advanced disease. According to the Discharge Summary, this patient had multiple lytic lesions and plasmacytoma which indicates advanced disease.
