Abstract

Treatment of glioblastoma is challenging due to its aggressive and highly invasive
nature, and no significant advances in survival have been achieved recently. The aim of our retrospective
study was identification of predictive factors and consequent survival outcome in patients who
underwent surgical and oncologic treatment of glioblastoma. The study was conducted at the Department
of Neurosurgery, Osijek University Hospital Centre. The authors designed a retrospective cohort
study in 63 patients who underwent surgical and oncologic treatment between January 1, 2012 and
December 31, 2017. Data were collected by reviewing medical records of the patients with histologically
proven glioblastoma. Statistical analysis of study results revealed a significant impact of postoperative
radiotherapy (p=0.002) and chemotherapy (p=0.016) on progression-free survival and overall
survival (p=0.001 and p=0.009, respectively). Postoperative Karnofsky performance scale (p=0.027)
was found to be significant in progression-free survival, and so was the interval between surgery and
commencement of oncologic therapy (p=0.049). In conclusion, overall survival and prognosis in the
treatment of glioblastoma remain poor, although prompt approach in postoperative adjuvant treatments
improved progression-free survival.
