ABSTRACT

Introducción: El linfoma difuso de células grandes B es el subtipo histológico más común de los linfomas no Hodgkin de curso agresivo. Objetivo: Caracterizar el comportamiento de pacientes adultos con linfoma difuso de células grandes B. Métodos: Se realizó un estudio observacional, descriptivo, longitudinal y retrospectivo que incluyó 56 pacientes adultos con linfoma difuso de células grandes B atendidos en el Instituto de Hematología e Inmunología desde enero 1998 hasta diciembre 2018. Resultados: El 55,4 por ciento de los pacientes fueron del sexo masculino; predominó el color de piel blanco (76,8 por ciento) y el grupo de 59 a 78 años (44,6 por ciento). Prevalecieron pacientes con comorbilidades fundamentalmente la hipertensión arterial (35,7 por ciento) y con validismo regular (55,4 por ciento). El 53,6 por ciento de los pacientes estaba en estadio IV al diagnóstico; predominaron los pacientes con síntomas B en 85,7 por ciento y fue más frecuente el grupo de riesgo bajo intermedio en 35,7 por ciento. El esquema más empleado fue R-CHOP, con el que se logró 85,7 por ciento de remisión completa. El 17,9 por ciento de los pacientes fallecieron y 41,1 por ciento recayeron. La sobrevida global a los 3, 5 y 10 años fue de 87,0 por ciento, 83,0 por ciento, y 80,0 por ciento, respectivamente. La sobrevida libre de enfermedad a los 3, 5 y 10 años fue de 74,0 por ciento, 67 por ciento y 56 por ciento, respectivamente. Conclusiones: La sobrevida global y la sobrevida libre de enfermedad de los pacientes fueron altas(AU)


Introduction: Diffuse large B-cell lymphoma is the most common subtype of aggressive non-Hodgkin lymphoma. Objective: Characterize the behavior of adult patients with diffuse large B-cell lymphoma. Methods: An observational retrospective longitudinal descriptive study was conducted of 56 adult patients with diffuse large B-cell lymphoma attending the Institute of Hematology and Immunology from January 1998 to December 2018. Results: Of the patients studied, 55.4 percent were male, and a predominance was found of white skin color (76.8 percent) and the 59-78 years age group (44.6 percent). Patients with comorbidities prevailed, mainly hypertension (35.7 percent) with an ability to perform activities of daily living (55.4 percent). 53.6 percent of the patients were in stage IV at diagnosis. Patients with type B symptoms prevailed with 85.7 (AU) , and the low to intermediate risk group was the most common with 35.7 percent. The regimen most frequently used was R-CHOP, obtaining 85.7 percent complete remission. 17.9 percent of the patients died and 41.1 percent relapsed. Overall survival at 3, 5 and 10 years was 87.0 percent, 83.0 percent and 80.0 percent, respectively. Disease-free survival at 3, 5 and 10 years was 74.0 percent, 67 percent and 56 percent, respectively. Conclusions: Overall and disease-free survival were high(AU)

ABSTRACT

In neurolymphomatosis, malignant lymphocytes infiltrate the peripheral nervous system in the presence of a known or unknown hematological malignancy. This report describes the findings of diffusion-weighted MRI and F-FDG PET/CT in a 65-year-old man with hoarseness. Results revealed a mass with restricted diffusion on diffusion-weighted imaging in the right visceral vascular space, increased uptake of F-FDG, and other masses at distant peripheral nerves. Restaging PET/CT showed involvement of the right brachial plexus and right sciatic nerve. Biopsy and immunohistochemistry of the right vagus nerve and cervical lymphadenopathy revealed a diffuse large B-cell non-Hodgkin lymphoma.

ABSTRACT

Rituximab is a treatment option to non-Hodg kin's diffuse large B-cell lymphoma (NHDLBCL) in advanced stage and comorbility. It is known the cardiotoxicity effect of this drug, but there is no previous report describing a complete atrioventricular block (CAVB) secundary to treatment with Rituximab. We present an elderly woman treated with monotherapy with Rituximab who experienced a CAVB after administration of the fifth dose of this drug.

ABSTRACT

El linfoma gastrico primario, entidad relativamente infrecuente, viene aumentando su incidencia como resultado de las mejores técnicas endoscópicas que permiten la toma de suficiente material de biopsia para el diagnóstico histopatológico. El diagnóstico diferencial histológico se hace con el carcinoma gastrico y con el pseudolinfoma gastrico. La clasificación del estadio de la enfermedad es necesaria para planear el tratamiento y valorar el pronóstico. La resección quirúrgica como modalidad terapéutica ha venido siendo reemplazada por esquemas de quimioterapia y radioterapia combinadas con menores ratas de morbimortalidad y mejores tasas de sobrevida.
