Association between treatment-related lymphopenia and survival in glioblastoma patients following postoperative chemoradiotherapy.

Purpose: Our study investigated the association between treatment-related lymphopenia and overall survival (OS) in a series of glioblastoma (GBM) patients. We also explored clinical and dosimetric predictors of lymphocytes depletion.

Methods: Between 2015 and 2019, 64 patients were treated at the same institution with postoperative chemoradiotherapy.
