HOUT-27. TREATMENT PATTERNS AND SURVIVAL IN PATIENTS WITH GLIOBLASTOMA: A RETROSPECTIVE DATABASE ANALYSIS USING US ELECTRONIC HEALTH RECORDS (EHR)

BACKGROUND Glioblastoma (GBM) represents 14.9% of all primary brain tumors in the US with ≥12,000 new cases expected in 2017. Current management lacks any curative therapies and remains palliative through the use of surgery, postoperative radiotherapy and concurrent and adjuvant chemotherapy. This study compares guideline-recommended-care to current practice patterns in GBM patients treated in the community, which is largely unknown.
