Body mass index as a prognostic indicator of overall survival in glioblastoma: A systematic review and meta analysis.

Background: Many previous studies have investigated the prognostic value of body mass index (BMI) for GBM outcomes with varying results. We present a comprehensive literature review and meta-analysis investigating BMI as a prognostic value in GBM.

Methods: A systematic review of literature on adult patients with GBM published between 1999 and 2023 was conducted within OVID Medline, Pubmed, and Scopus.

Baseline single institutional retrospective review of body mass index (BMI) as a prognostic indicator in patients with newly diagnosed glioblastoma (GBM).

Purpose: Glioblastoma (GBM) is the most common primary brain cancer in adults with a very poor prognosis. Metabolic drivers of tumorigenesis are highly relevant within the central nervous system, where glucose is the critical source of energy. The impact of obesity on survival outcomes in patients with GBM is not well established.
