• W2912883096 abstract "Primary lymphoma of the central nervous system is a variety of non-Hodgkin's lymphoma that accounts for 4-5% of intracranial tumours and 5% of all lymphomas. It has its origin in the brain, the eyes, the leptomeninges and the spinal cord with no systemic evidence of lymphomatoid activity; the subtype of lymphoma is predominantly of B-type cells.We conducted a descriptive study of the patients diagnosed with primary brain lymphoma who were attended to at third-level centres in Mexico between the years 1980 and 2016. Patients who had been screened for systemic lymphoma were included. The results were analysed by means of simple frequencies, and disease-free and overall survival time was analysed by Kaplan-Meier curves; the differences among curves were analysed by means of log rank.Of a total of 215 patients, there were only 74 cases. By sex, 45% were females and 55% were males. Regarding age, 36.7% were over 60 years old. The most frequent clinical manifestations were motor loss (60%) and cognitive disorders (52%). Most patients received some form of chemotherapy (89%). The only significant factor for radiological response and clinical prognosis was the combined use of radiochemotherapy (p = 0.04493).Lymphoma is a tumorous condition with a high clinicoradiological response to treatment, although the response is not long-lasting. Its early identification and multidisciplinary management are essential for a more favourable prognosis in these patients.Linfoma primario del sistema nervioso central: experiencia clinica en un centro neurologico.Introduccion. El linfoma primario del sistema nervioso central es una variedad de linfoma no Hodgkin que representa el 4-5% de los tumores intracraneales y el 5% de todos los linfomas. Se origina en el encefalo, los ojos, la leptomeninge y la medula espinal sin evidencia sistemica de actividad linfomatoide; el subtipo de linfoma mayoritariamente es de celulas de tipo B. Pacientes y metodos. Estudio descriptivo de los pacientes diagnosticados con linfoma cerebral primario que fueron atendidos en centros de tercer nivel en Mexico entre los años 1980 y 2016. Se incluyo a los pacientes que contaran con cribado para busqueda de linfoma sistemico. Los resultados se analizaron mediante frecuencias simples; en el caso del tiempo libre de enfermedad y supervivencia global, mediante curvas de Kaplan-Meier, y las diferencias entre curvas, mediante log rank. Resultados. En un total de 215 pacientes solo hubo 74 casos. El 45% fueron mujeres y el 55%, hombres. El 36,7% eran mayores de 60 años. Las manifestaciones clinicas mas frecuentes fueron deficit motor (60%) y alteraciones cognitivas (52%). La mayoria recibio alguna forma de quimioterapia (89%). El unico factor significativo para respuesta radiologica y pronostico clinico era el uso combinado de radioquimioterapia (p = 0,04493). Conclusion. El linfoma representa una patologia tumoral con alta respuesta clinicorradiologica al tratamiento, aunque la respuesta no es duradera. Es fundamental su identificacion temprana y el tratamiento multidisciplinario para el mejor pronostico de estos pacientes." @default.
