Cytogenetic anomalies in Multiple Myeloma patients:A single center study.
Abstract
Conventional karyotyping in the patients with Multiple myeloma (MM) is very important. Because chromosomal abnormalities which detected in these patients have diagnostic and prognostic value. In this retrospective study we aim to evaluate cytogenetic abnormalities in 133 MM patients which diagnosed at the Hematology Department of Hacettepe University. Samples were treated with trypsin and stained with Giemsa (GTG banding). 20 metaphases of each patient were examined and karyotypes were formed. Cytogenetic results of the patient’s bone marrow samples were not obtained in 19 patients, while in 116 patients karyotyping was performed. Among of these 116 patients showed that 80 patients had normal karyotpe while 34 patients had abnormal karyotypes. Both numerical and structural chromosomal anomalies were detected in patients with abnormal karyotype. Numerical and structural anomalies of chromosomes 1, 9, 16 and 13 were detected most frequently among these complex karyotypes. The anomalies we found in our patient group were consistent with the literature.
