Evaluación de desbalances genómicos en desórdenes de células plasmáticas

Abstract

Plasma cell disorders are widely heterogeneous B-cell neoplasms. The study of genetic alterations has allowed the definition of specific subgroups, and provided the basis for the identification of genes involved in the initiation and progression of these entities. Among them, are the rearrangements of the MYC gene and the deletion of CD27. The objective of the present study was to evaluate MYC and CD27 alterations in patients with plasma cell disorders. The results were correlated with the prognostic factors and the clinical evolution of patients. A total of 100 patients, 82 with multiple myeloma and 18 with monoclonal gammopathy of uncertain significance were studied. Results were compared with a control group of 55 patients with multiple myeloma without genetic alterations. Among multiple myeloma cases, 87.1% showed chromosomal and/or cytomolecular alterations. Additionally, we detected rearrangements of MYC and deletion of CD27 gene in 22.9% and 28.1% of patients, respectively. Cases with MYC rearrangements showed increased levels of calcemia and creatinine with respect to patients without MYC abnormalities and the control group. Patients with CD27 deletion had increased lactate dehidrogenase values compared to those without this abnormality and the control group. It should be noted that both MYC rearrangements and CD27 deletion were not found in patients with monoclonal gammopathy, reinforcing their role in the transformation process to multiple myeloma. Our results suggest the importance to include the analysis of MYC and CD27 genes in the panel of genetic studies of multiple myeloma at diagnosis, in order to a better clinical-biological delineation of this entity, contributing to its genetic characterization.

Los desórdenes de células plasmáticas son neoplasias de células B, ampliamente heterogéneas. Los estudios genéticos han permitido identificar genes involucrados en la iniciación y progresión de estos desórdenes. Entre ellos, encontramos los rearreglos del gen MYC y la deleción de CD27. El objetivo del presente estudio fue evaluar ambos genes a nivel citogenético y citomolecular en pacientes con desórdenes de células plasmáticas. Se estudiaron un total de 100 casos, 82 con mieloma múltiple y 18 con gammapatía monoclonal de significado incierto. Los resultados se compararon con un grupo control de 55 pacientes con mieloma múltiple sin alteraciones genéticas. Todos los pacientes con gammapatía monoclonal mostraron cariotipo normal sin anomalías por FISH, en tanto que 87,1% de los casos con mieloma múltiple presentaron alteraciones. Adicionalmente, detectamos rearreglos del gen MYC y deleción de CD27 en el 22,9% y el 28,1% de los pacientes, respectivamente. Los casos con MYC alterado mostraron valores elevados de calcemia y creatinina respecto de los casos sin anomalías de MYC y del grupo control. En tanto que los pacientes con deleción de CD27 presentaron valores elevados de lactato de hidrogenasa respecto de aquellos sin esta anomalía y del grupo control. Cabe destacar que ningún paciente con gammapatía monoclonal mostró alteraciones en los genes MYC y CD27, reforzando su rol en la transformación a mieloma múltiple. Nuestros resultados sugieren la importancia de poder incluir el análisis de ambos genes en el panel de estudios genéticos de mieloma múltiple al momento del diagnóstico tendiente a una mejor delineación clínico-biológica de esta entidad, contribuyendo a la caracterización genética de la misma.
