SUMMARYThe incidence of Primary Central Nervous System Lymphoma (PCNSL) is increasing rapidly. PCNSL is an important lethal complication in AIDS patients. Objective: Our objective was to study the natural history and prognostic factors for survival in patients with AIDS related PCNSL. Material and methods: This is a retrospective cohort study of 75 patients with the diagnosis of AIDS related PCNSL followed at Jackson Memorial Hospital University of Miami. Results: The median age was 37 years. Males comprised 84% of the patients and 55% of the patients were Hispanic. The most common HIV risk factors were homosexuality and multiple sexual partners. The median CD4 count was 15/~L and the median LDH was 1.5x normal. CT Scans of the brain showed multiple lesions in 44% of the patients. Single-Photon Emission CT Scan (SPECT) Thallium-201 of the brain was performed in 2/3 of patients. The most common histologies were immunoblastic and large cell lymphoma. Cranial radiation was given to 72% of the patients and 55% of them did not completed. The median survival of the group was 1.3 months. Univariate and multivariate analysis showed that longer survival was associated with good performance status (ECOG=1-2 Vs 3-4). The presence of prior opportunistic infections, risk factors for AIDS, CD4 counts, level of LDH, ethnicity, gender, duration of symptoms before diagnosis, and race did not influence survival. Conclusions: PCNSL is a neoplasm with a very poor prognosis and short survival even with CNS radiation therapy. Performance status appears to be the main prognostic factor for survival. No significant differences in presentation or outcome were detected between the Hispanic and non-Hispanic patients. RESUMENLa incidencia del linfoma primario del sistema nervioso central (LPSNC) ha crecido rápidamente. El LPSNC as una complicación letal en pacientes con SIDA. Objetivo: Nuestro objetivo fue estudiar la historia natural, métodos diagnósticos, al tratamiento y los factores pronósticos para la sobrevida de 75 pacientes con LPSNC y SIDA seguidos en el Jackson Memorial Hospital/Universidad de Miami. Resultados: La edad media fue de 37 años. El 84% de los pacientes eran hombres y el 55% hispanos. Factores de riesgo más comunes para SIDA fueron homosexualidad y múltiples compañeros sexuales. La cuenta promedio de CD4 fue de 15/ul y al promedio de LDH fue 1.5 veces al normal. La tomografía computarizada del cerebro mostraba lesiones múltiples en el 44% de los pacientes. Gammagrafia computarizada de emisión de fotones con talio-201 (SPECT) del cerebro se realizó en 2/3 de los pacientes. Las histologías más comunes en las biopsias fueron: linfoma inmunoblástico y linfoma de células grandes. La radiación craneana fue ineficiente en el 50% de los pacientes tratados. La sobrevida promedio del grupo fue de 2.2 meses. Análisis univariado y multivariado mostraron que la mayor sobrevida se asociaba con una buena capacidad funcional (ECOG=1-2 vs 3-4). La presencia previa de infecciones oportunistas, la presencia de factores de riesgo de SID...
