espanolPara identificar una patologia cada vez mas comun, conocida como mieloma multiple, es necesario hacer alusion de los factores especificos que la caracterizan. Para ello existen los clasicos criterios conocidos como CRAB (hipercalcemia, insufi- ciencia renal, anemia y lesiones liticas), siendo la insuficiencia renal una de sus complicaciones mas frecuentes. Reciente- mente se han descrito tres biomarcadores indiscutibles para el apoyo diagnostico del mieloma multiple, que son: mas del 10% de celulas plasmaticas clonales en medula osea o biopsia que corrobora la presencia de un plasmocitoma, relacion de cade- nas ligeras ≥ 100 mg/dl y mas de una lesion focal en resonancia magnetica. Se debe tomar siempre en cuenta el diagnostico diferencial con leucemia de celulas plasmaticas, plasmocitoma oseo solitario y plasmocitoma extramedular. Al ser una enfer- medad incurable, se ha investigado mucho en cuanto al manejo terapeutico, el cual tiene como objetivo principal la desapa- ricion de las celulas plasmaticas y la mejoria clinica del paciente. El primer farmaco que demostro algun beneficio fue el melfalan en el ano 1958 y posteriormente al adicionar un esteroide como segundo farmaco se logro mejorar las tasas de respuesta. Despues se fueron estudiando diferentes moleculas, con las que se han realizado multiples combinaciones, alcan- zando mejores tasas de supervivencia global y supervivencia libre de progresion. Anos mas tarde, con la llegada de los inhi- bidores de proteosoma como el bortezomib, asi como de los agentes inmunomoduladores como la talidomida y la lenalido- mida, se presenta un giro importante en la enfermedad, ya que se logran respuestas mas profundas, periodo de remisiones mas prolongadas y mejoria en la calidad de vida de los pacientes. Este consenso tiene la finalidad de integrar a un grupo de especialistas mexicanos y promover la actualizacion de esta patologia. EnglishTo identify this increasingly common pathology, known as Multiple Myeloma, it is necessary to refer to the specific factors that characterize it; to this end, the classic criteria known as CRAB (hypercalcemia, renal failure, anemia and lytic lesions) are available, in which renal failure is one of the most frequent complications. Recently, 3 indisputable biomarkers have been described for the diagnostic support for Multiple Myeloma, which are: more than 10% of clonal plasma cells in BM or, a biop- sy that corroborates the presence of a plasmacytoma, light chain ratio ≥100 mg/dL and more than one focal lesion on mag- netic resonance imaging (MRI). A differential diagnosis for plasma cell leukemia, solitary bone plasmacytoma, and extramed- ullary plasmacytoma should always be considered. Being this an incurable disease, a lot of research has been done regarding its therapeutic management, whose main objective is the disappearance of plasma cells and the patient clinical improvement. Melphalan was the first drug that showed a benefit in 1958 and afterwards, with the addition of a steroid as a second drug, it was possible to improve response rates. Subsequently, different molecules were studied, forming multiple combinations, and achieving better rates of Overall Survival and Progression-Free Survival. Years later, with the arrival of proteasome inhibitors such as bortezomib, and immunomodulators such as thalidomide and lenalidomide, an important turnaround in the disease has been seen, as deeper responses, more prolonged remissions, and improvement in the quality of life of patients have been achieved. This consensus has the purpose of integrating a group of Mexican specialists and promoting the updating of this pathology.

Hodgkin's lymphoma is due to the clonal transformation of cells originating from B lymphocytes, generating the pathognomonic binucleate Reed-Sternberg cells. Hodgkin's lymphoma is a B cell disease with a bimodal distribution, with higher incidence in adolescence and the third decade of life, showing a second peak in people over 55 years of age. Classic Hodgkin lymphoma cells routinely undergo gene expression reprogramming, as they lose the expression of most of the typical B-cell genes and acquire the expression of multiple genes that are typical of other types of cells in the immune system. The treatment algorithm will depend on whether it is classic or predominantly lymphocytic HL, if it is early stage with unfavorable prognostic markers or not, the initial management regimen, and whether there is bulky disease, among the most relevant variables.

To identify this increasingly common pathology, known as multiple myeloma (MM), it is necessary to refer to the specific factors that characterize it; to this end, the classic criteria known as CRAB (hyperkalemia, renal failure, anemia, and lytic lesions) are available, in which renal failure is one of the most frequent complications. Recently, three indisputable biomarkers have been described for the diagnostic support for MM, which are: more than 10% of clonal plasma cells in bone marrow or, a biopsy that corroborates the presence of a plasmacytoma, light chain ratio ≥ 100 mg/dL and more than one focal lesion on magnetic resonance imaging. A differential diagnosis for plasma cell leukemia, solitary bone plasmacytoma, and extramedullary plasmacytoma should always be considered.
