    An exclusive production of light chains can be found in ~15% of myeloma cases, and in these light-chain multiple myeloma (LC-MM) cases, the phenotype remains unchanged throughout subsequent progression and relapse. Once established, it suggests that this phenotype is maintained by the ‘feeder cell’ that re-populates the tumor bulk as disease re-emerges<br/
