Abstract:Objective To investigate the influencing factors for the postoperative survival of high-grade glioma.Methods A total of 92 patients who were diagnosed with high-grade glioma (WHO grade Ⅲ-IV) at initial diagnosis from January 2014 to August 2016 were enrolled. The Kaplan-Meier method was used to evaluate survival rate, the log-rank test was used for univiriate analysis, and the Cox regression model was used for multivariate analysis.Results The median survival time was 15 months, and the median progress-free survival was 8 months. The overall tumor resection rate was 72.83%, and the 1-, 2-, 3-, and 4-year survival rates were 56.5%, 35.9%, 30.4%, and 25.4%, respectively. The log-rank univariate analysis showed that the prognosis of high-grade glioma was associated with age, preoperative Karnofsky Performance Scale score, size/number/location of tumors, whether multiple cerebral lobes or motor function regions were involved, extent of resection, pathological grade, presence or absence of isocitric dehydrogenase gene mutation, presence or absence of methylation of O-6-methylguanine-DNA methyltransferase gene promoter, Ki 67 index, whether radiotherapy and/or chemotherapy were performed after surgery and the mode of radiochemotherapy, and whether active treatment was given after recurrence (P<0.05). With a significance level of α=0.01, the Cox multivariate analysis showed that age, extent of resection, and whether radiotherapy and/or chemotherapy were performed after surgery were independent risk factors for the prognosis of high-grade glioma (P<0.01).Conclusions Patients with high-grade glioma with an age of onset of <65 years, total tumor resection, and concurrent chemoradiotherapy and adjuvant chemotherapy after surgery tend to have good prognosis.
