Second surgery for glioblastoma. A 4-year retrospective study conducted in both the Montpellier and Nice Departments of Neurosurgery. A literature review

Background and purpose. - Glioblastoma, the most common malignant primary brain tumor in adults, is usually rapidly fatal. The Current care standards for newly diagnosed glioblastoma consist, when feasible, in surgical resection, radiotherapy, and chemotherapy, as described in the Stupp protocol. Despite optimal treatment, nearly all malignant gliomas recur. If the tumor is symptomatic for mass effect, repeated surgery may be proposed. Methods. - We retrospectively analyzed the survival of patients with histologically confirmed primary glioblastoma (WHO grade 4) who were operated in two centers between January 2004 and December 2007. All patients who underwent a second resection for recurrent glioblastoma were included. Results. - During this period, 320 patients were operated in the two centers, with 240 surgical resections and 80 surgical biopsies. In the surgical resection group, 8.3% (20 patients) underwent a second Surgical resection for glioblastoma. The mean age was 52 years. At the end of the study, seven patients were alive. The median survival was 24 months and progression-free survival was 7.5 months. Conclusions. - The effect of resection Of recurrent glioblastoma on Survival has not been extensively studied. NO randomized trials have been conducted. Our data were globally identical to other retrospective studies. Selected patients with recurrent glioblastoma may be candidates for repeated surgery when the situation appears favorable based on assessment of the individual patient's factors. Factors such medical history, neurological status, location of the tumor, and progression-free survival have been proven in retrospective studies to give better results. (C) 2009 Elsevier Masson SAS.
