Hello Everyone. last Aug. 2025, was diagnosed with a solitary Plasmacytoma in the L2. Radiation treatment only reduced the lesion by 20% and the medical team wants to attack this one spot systemically with chemo/immunotheopy for the next year. Does anyone know of a successful, next step in treating a radiation resistant solitary Plasmacytoma? ( before its possibly becomes multiple myeloma or vertebrae collapses)
