Prognostic factors which affect treatment results of glioblastoma multiforme (GBM; WHO Grade IV) patients has been investigated in many researches. For these patients determination of prognostic factors helps generating multimodal therapy protocols. For this purpose, in the Baskent University Medical School, Neurosurgery Clinic, Adana Medical Research Center, specific characteristics of GBM patients who have surgery retrospectively investigated and factors which affect prognosis has been determined. ⋯ When independent prognostic factors were examined ,median survival found out 7.8 months longer fort he patients whose postoperative KPS were >or=70, 5.7 months longer for the patients who had radical resection, 6.6 months longer for the patients who had multiple operations. Although patients who had ConcT with adjuvant TMZ had 1.7 months longer survival compared to patients who had only adjuvant RT, it was not determined as an independent prognostic factor.
