Abstract

Glioblastoma (GBM) is an aggressive central nervous system tumor with a poor prognosis. This study was conducted to determine any comorbid medical conditions that are associated with survival in GBM. Data were collected from medical records of all patients who presented to VCU Medical Center with GBM between January 2005 and February 2015. Patients who underwent surgery/biopsy were considered for inclusion. Cox proportional hazards regression modeling was performed to assess the relationship between survival and sex, race, and comorbid medical conditions. 163 patients met inclusion criteria. Comorbidities associated with survival on individual-characteristic analysis included: history of asthma (Hazard Ratio [HR]: 2.63; 95% Confidence Interval [CI]: 1.24-5.58; p = 0.01), hypercholesterolemia (HR: 1.95; 95% CI: 1.09-3.50; p = 0.02), and incontinence (HR: 2.29; 95% CI: 0.95-5.57; p = 0.07). History of asthma (HR: 2.22; 95% CI: 1.02-4.83; p = 0.04) and hypercholesterolemia (HR: 1.99; 95% CI: 1.11-3.56; p = 0.02) were associated with shorter survival on multivariable analysis. Surgical patients with GBM who had a prior history of asthma or hypercholesterolemia had significantly higher relative risk for mortality on individual-characteristic and multivariable analyses.
