Abstract : Immunophenotyping has become an invaluable tool in the management of hematological malignancies and is increasingly finding a role in the diagnosis and monitoring of plasma cell disorders. The aim of the study was to provide an accurate diagnosis of multiple myeloma by application of flow cytometry immunophenotyping. A cross sectional descriptive study was conducted at Department of Clinical Hematology, Yangon General Hospital from September 2015 to August 2016. Multiparametric flow cytometry immunophenotyping was performed using monoclonal antibodies against CD56, CD19, CD138, CD38 and CD45. A total of 40 clinically suspected cases of multiple myeloma were included for the study. Among the 40 cases, 25 cases (62.5%) were diagnosed as multiple myeloma by the positive expression of CD138 or CD38, negative CD19 expression, weak or negative CD45 expression and positive or negative CD56 expression. Age of the patients ranged from 49 years to 89 years. The male to female ratio was 1.1:1. Serum protein electrophoresis and densitometer reading were performed in all cases for detection of monoclonal band and monoclonal protein concentration. Monoclonal band was detected visually and estimation of monoclonal protein was done by densitometer. Among the 40 cases, 25 cases (62.5%) had monoclonal gammopathy. Among these cases, 20 cases (80%) had monoclonal band in the gamma () region and 5 cases (20%) had in the beta () globulin region. The mean concentration of monoclonal protein was 4.50 g/dl, with a range of 2.28 to 7.95 g/dl. The remaining 15 cases (37.5%) were not detected monoclonal band. In conclusion, flow cytometry immunophenotyping is useful tool for the diagnosis of multiple myeloma and it should be included as a routine assay in monoclonal gammopathy patients.
