Multiple myeloma is a type of cancer that affects the plasma cells in the bone marrow. In this abstract, we discuss the cytogenetic abnormalities in multiple myeloma patients and their correlation with age and gender. We also describe the techniques used for cytogenetic analysis in the Indian population. Our study included 70 patients with multiple myeloma, and cytogenetic analysis was performed using conventional karyotyping and Fluorescence In-situ Hybridization (FISH) techniques. We observed a higher incidence of cytogenetic abnormalities in patients above 60 years of age, with male predominance. FISH analysis showed a higher detection rate of cytogenetic abnormalities compared to conventional karyotyping. FISH also provided additional information on the extent and complexity of the chromosomal aberrations. It is a cytogenetic technique that uses fluorescently labelled probes to detect genetic abnormalities in the chromosomes of cells obtained from bone marrow. This analysis can provide valuable information about the type and stage of the disease, Translocations t(4;14),t(14;16), t(6;14), and t(14;20) were associated with anaemia, t(4;14) was associated with a higher serum monoclonal protein and plasma cell proliferation. Monosomy 13 is associated with a short survival rate with transition monoclonal gammopathy. In conclusion, our study confirms the age and male predominance in multiple myeloma and highlights the importance of cytogenetic analysis in the diagnosis and prognosis of the disease. By studying the chromosomal abnormalities in MM, we can gain insights into the underlying causes of the disease. In this study, we will discuss the cytogenetics of MM and explore how it can help understand the genetics of cancer. The study highlights the chromosomal abnormalities associated with MM and its implications for diagnosis and prognosis.
