Plasma Cell Leukaemia (plasma + cell_leukaemia)
Selected AbstractsLow cost autologous peripheral blood stem cell transplantation performed in a municipal hospital for a patient with plasma cell leukaemiaINTERNATIONAL JOURNAL OF LABORATORY HEMATOLOGY, Issue 3 2002K. Ghosh Autologous peripheral blood stem cell transplantation (PBSCT) is a costly procedure. In India, the cost varies from US$20 000 to 25 000 and most patients cannot afford it. Using several cost-cutting measures, we were able to treat a patient with plasma cell leukaemia by autologous PBSCT. A 42-year-old-male presented with plasma cell leukaemia. He was treated with VAD therapy, followed by high-dose cyclophosphamide and granulocyte colony-stimulating factor (G-CSF) for mobilization of peripheral blood stem cells. The patient was conditioned with high dose melphalan, followed by autologous PBSCT. The procedure was performed in a municipal hospital in which there was no prior experience with stem cell transplantation. Costs were reduced by: (i) using oral medication whenever possible; (ii) having a relative of the patient prepare his food under medical guidance; (iii) starting G,CSF on day 7 rather than on day 1; (iv) short-term storage of the PBSC in an ordinary refrigerator at 4 °C without cryopreservation; (v) infusing a large number of CD34+ cells, which shortened the time to engraftment; (vi) delegating many of the functions of a marrow transplant nurse to a resident physician. The cost of transplantation was thereby reduced to about US$ 6000, with successful engraftment by day +13. The patient remained in remission for 7 months, after which he relapsed and was treated with chemotherapy and electron beam radiation to the skin.

Interphase cytoplasmic fluorescence in situ hybridisation was used to investigate the CKS1B amplification status (at 1q21) in clonal plasma cells from 123 patients: 23 monoclonal gammopathy of undetermined significance (MGUS), 75 multiple myeloma (MM) and 26 plasma cell leukaemia (PCL). While CKS1B amplification was absent in MGUS patients, such amplification (3,8 copies) was detected in 36% of newly diagnosed MM, 52% relapsed MM and 62% PCL (P < 0·001). Our results suggest that CKS1B amplification is associated with transformation from MGUS to MM and progression to PCL. [source] | ||||||||||
