主 题：Primary Cerebral Lymphoma (PCL) Retrospective Study Management
摘 要：Primary cerebral lymphoma (PCL) is a form of extranodal non-Hodgkin’s lymphoma with a poor prognosis. Very few cohorts have been reported in the literature. It is a rare form in 1% of extranodal lymphomas, and 3% to 4% of brain tumors. The most common histological type is diffuse large B-cell lymphoma. Survival is improved by combining immunotherapy with chemotherapy. This is a descriptive retrospective study conducted at the Casablanca hematology center over a period of 9 years. The aim of this study was to report our experience by studying the clinical, paraclinical, therapeutic and evolutionary profile of patients with primary cerebral lymphoma. We present a study of 22 patients with PCL. The clinical, radiological and histological findings are shown along with the results of treatment. Patients were aged 25 - 75 years (mean 47 years) with a male predominance (77%). Computed tomography (CT) scans were performed on 16 patients (73%) and Brain magnetic resonance imaging for 16 patients (73%). Typically, lesions were multiple, isodense, and showed uniform enhancement with contrast medium. Immunocytochemical studies demonstrated 21 B-cell and 1 mantle-cell lymphomas. All patients received chemotherapy through high-dose MTX with whole brain radiotherapy (WBRT). After a median follow-up of 19 months, 54% are in complete remission, 32% have died, and 14% are lost to follow-up. Overall survival at 24 months and 36 months were 72% and 52%. The event-free survival at 24 months and 36 months were 60% and 48%. This study was to investigate the clinical features of PCNSL, and evaluate the efficacy of high-dose methotrexate (MTX)-based chemotherapy for immunocompetent Moroccan patients with PCNSL.
