Abstract

Object. Multicentric diffuse low-grade gliomas (DLGGs) are defined as widely separated lesions in different lobes or hemispheres where there is no anatomical continuity between lesions. This condition is rare and its clinicopathological characteristics have been scarcely described in the literature. Here, the authors report the first consecutive surgical series of multicentric DLGGs with functional and oncological outcomes. Methods. A retrospective review of patients surgically treated for histopathologically confirmed multicentric DLGGs between 2000 and 2012 was performed. Information regarding clinical features, surgical procedures, histopathological results, and clinical outcomes was collected and analyzed. Results. Five consecutive patients were included in this study. There were 3 men and 2 women, whose mean age was 27.4 years (range 23-35 years). The mean follow-up period after surgery was 46 months (range 11-138 months). Gross-total or subtotal resection was achieved in all cases, using a single surgery in 3 patients and a 2-stage surgery in 2 patients. There was no mortality or permanent morbidity associated with surgery. The Karnofsky Performance Scale score ranged between 90 and 100 in all cases. Adjuvant chemotherapy was administered in 2 patients because of tumor regrowth with no malignant transformation. Conclusions. Multicentric DLGGs can be removed safely without inducing severe permanent neurological deficits. Interestingly, a single-stage resection of multiple lesions within different lobes may be performed if tumors are located in the same hemisphere. Therefore, the authors suggest considering surgery as the first therapeutic option for multicentric DLGGs, as in solitary DLGGs.
