High Dose Therapy with Autologous Stem Cell Transplantation for Solitary Bone Plasmacytoma Complicated by Local Relapse or Isolated Distant Recurrence

We report three patients with solitary bone plasmacytoma (SBP) who developed either local recurrence within the radiotherapy field or an isolated distal recurrence and who were treated with high dose therapy supported by autologous stem cell transplantation. All patients remain without evidence of disease for 4-10 years after the procedure. High dose therapy may be of value and require further study in patients with SBP who develop local or distant failure.
