Influence of Oncotherapy and Clinical Parameters on Survival of Glioblastoma Patients: A Single Center Experience

Background: Routine administration of temozolomide (TMZ) in the treatment protocol of glioblastoma in the last few years resulted in improving survival parameters of these patients but efficacy of supplementary bevacizumab (BVC) monotherapy has not been evidently proven.

description Background: Routine administration of temozolomide (TMZ) in the treatment protocol of glioblastoma in the last few years resulted in improving survival parameters of these patients but efficacy of supplementary bevacizumab (BVC) monotherapy has not been evidently proven. In this study, the effectiveness of different postoperative therapy for glioblastoma patients treated in our institute was evaluated. In addition, the prognostic value of clinical parameters on survival was also analyzed. Methods: Accordance of clinical parameters (age, gender, tumor localization, size, side, Karnofsky performance score, and extension of tumor removal), postoperative treatment (radiotherapy [RT], RT + TMZ, RT + TMZ + BVC), and survival data were tested by 104 patients operated on glioblastoma in the Department of Neurosurgery, University of Debrecen between 2002 and 2012. Results: Concurrent chemo-RT resulted in significant longer overall survival (OS) than RT alone (PRTvs.RT + TMZ = 0.0219) and BVC treatment after progression during TMZ also elongated survival significantly (PRT vs. RT + TMZ + BVC < 0.0001; PRT + TMZvs.RT + TMZ + BVC = 0.0022), respectively. Clinical parameters showed no significant influence on OS in comparison with different methods of postoperative oncotherapy. Conclusions: Both TMZ and BVC had a beneficial effect on glioblastoma patients' survival, but tested clinical parameters showed no evident accordance with final outcome. Although neurosurgery has an indispensable role in resecting space occupying tumors and providing good postoperative performance score patients for oncotherapy, the survival of glioblastoma patients depends rather on radio- and chemo-sensitivity than tested clinical parameters.
