Purpose: Social determinants of health including neighborhood socioeconomic status, have been established to play a profound role in overall access to care and outcomes in numerous specialized disease entities. To provide glioblastoma multiforme (GBM) patients with high-quality care, it is crucial to identify predictors of hospital length of stay (LOS), discharge disposition, and access to postoperative adjuvant chemoradiation. In this study, we incorporate a novel neighborhood socioeconomic status index (NSES) and develop three predictive algorithms for assessing post-operative outcomes in GBM patients, offering a tool for preoperative risk stratification of GBM patients.

Article Synopsis
  • Glioblastoma patients often experience functional deficits after surgery, which can negatively impact their daily activities and overall recovery outcomes.
  • A study involving 600 adult glioblastoma patients found that lower scores on the AM-PAC mobility and activity assessments were linked to longer hospital stays, higher chances of readmission, and shorter survival times.
  • The findings suggest that AM-PAC scores could provide valuable insights for predicting recovery and aiding in treatment decisions for glioblastoma patients post-operatively.

Objective: Patients with glioblastoma (GBM) often undergo surgery to prolong survival. However, the use of surgery, and more specifically achieving gross total resection (GTR), in patients >80 years old has yet to be fully assessed. Using the Surveillance, Epidemiology, and End Results (SEER) database, we aim to assess the efficacy of surgical resection, radiotherapy (RT) and chemotherapy (CT) on overall survival (OS) in very elderly GBM patients compared to elderly counterparts (age 65-79 years).
