RAEZ, Luis E; ANGULO, Juanita  and  RESTREPO, Alvaro. Diagnostic and treatment of patients with primary lymphomas of the central nervous system and required inmunodeficiency syndrome. Rev Med Hered [online]. 1999, vol.10, n.3, pp.96-104. ISSN 1018-130X.

The 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 were 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. ( Rev Med Hered 1999; 10: 96-104 ).
