Myelomonocytic antigen positive multiple myeloma

Myelomonocytic antigen positive multiple myeloma.

In a four year span, between 1983 and 1987, 215 bone marrow and cell culture samples from 125 myeloma patients were immunotyped and coexpression of myelomonocytic and plasma cell antigens occurred in 16 (13%). We employed both immunohistochemical and flow cytometry methods including coplots and double labelling. Three types of myeloma cases were found: (1) those with isolated myeloid antigen co...

Multiple Myeloma Update

This literature review presents the most recent developments in the management of multiple myeloma, which is characterized by the presence of abnormal plasma cells (myeloma cells) that accumulate into the bone marrow. Aspects related to pathophysiology, clinical manifestations, laboratory, study and treatment are described. These pieces of information  are necessary to accomplish a better ...

Treatment of Multiple Myeloma

Les traitements classiques de myelome multiple et les schemas differents proposes ont ete mis en revue.  La poly chimiotherapie de la maladie avec une com-binaison de cyclophosphamide, B.C.N.U. Alkeran, Perdnisone et Vincristine a donnee une meilleur Resultat ceci surtout dans les formes graves et rapidement progressive de la maladie. D'autres sehemas therapeutiques sont en cours. 

Myelomonocytic myeloma cell line (LB 84-1).

A human cell line (LB 84-1) has been established from the bone marrow of a patient with Bence-Jones myeloma. Coexpression of plasma cell (Leu[CD38]) and myelomonocytic antigens (Leu MI[CD15], Leu M5 [CD11c], MY7 [CD13] plus butyrate and chloracetate esterase) proved to be an unusual but sustained feature of this cell line. The plasma cell phenotype with multinuclearity was retained. Shared majo...
