Prise en charge des gliomes de bas grade: série rétrospective de 201 patients.

Abstract

BACKGROUND AND PURPOSE: Optimal treatment for low-grade glioma remains controversial. Moreover, though surgery is recommended for disease management, evidence is lacking concerning the appropriate extent of surgery and the use of adjunctive therapy. Available data is basically retrospective, coming from series with substantial limitations. We reviewed our institution's series in order to evaluate the efficiency of surgical management and the influence of the extent of surgical removal for patients with low-grade glioma. METHODS: Data were collected from a series of 201 patients who underwent first-intention therapy for low-grade glioma, the standard practice in our institution between 1994 and 2005. After applying certain exclusion criteria, we retained for analysis 123 patients with grade II glioma (WHO classification). We compared progression-free survival curves for the three surgical treatment groups defined as biopsy, partial removal, or total removal. RESULTS: Statistical evaluation of the progression free survival shows a benefit in total surgery as a first intention treatment. No statistical significance was demonstrated between partial surgery and stereotactic biopsy. CONCLUSION: For patients with low-grade glioma we recommend total surgical removal as first intention management.English AbstractJournal Articleinfo:eu-repo/semantics/publishe
