[Peripheral blood stem cell transplantation for rapidly spreading myeloma].
We report a case of rapidly spreading myeloma of immature cell morphology treated by peripheral blood stem cell transplantation (PBSCT). A 54-year-old man had a right orbital tumor, which subsequently was removed and proved to be plasmacytoma. Three years later a mass lesion appeared in his left lung and bilateral kidneys. The specimen obtained at lung biopsy confirmed the diagnosis of plasmacytoma. Serum M-protein, IgG lambda was increased, but there was no increase in plasma cells in the bone marrow. Since chemotherapy with VAD did not show any improvement, a high dose etoposide (500 mg/day, 4 days) was administered. When bone marrow suppression recovered, PBSCs were harvested (3.3 x 10(6)/kg). After conditioning therapy with cyclophosphamide (2.0 g/day, 2 days), etoposide (200 mg/day, 3 days) and ranimustine (200 mg/day, 2 days), the stored PBSCs were injected. Minor response was obtained and he was discharged. 2 months thereafter, it was found that plasma cells increased in the bone marrow. He died of pulmonary bleeding soon. Autopsy revealed immature plasma cell infiltration in multiple organs including the heart, liver, spleen, kidneys, intestine, bone and bone marrow.
