Concurrent Thermochemoradiotherapy in Glioblastoma Treatment: Preliminary Results

Abstract

Glioblastoma is the most frequent and aggressive primary brain tumor. The patient can be alive with this pathology using the modern standard of intensive combined treatment less than 2 years. Between December 2013 and August 2017, 30 patients with newly diag- nosed supratentorial glioblastoma had received concomitant chemoradiotherapy with transcranial radiofrequency hyperthermia. The gross total or the subtotal resection of the tumor was made previously in all cases. The median follow-up time after opera-tion achieved 12 months (95% confidence interval (CI): 8.5–23 months) in this study. The median disease-free survival time was 9.6 months (95% CI: 7.2–19.0 months). The median overall survival time of patients included in the study was 23.4 months. No increase in the systemic side effects of chemotherapy was found compared with the fre quency described in the population. Preliminary results had shown that the usage of concomitant thermochemoradiotherapy with transcranial radiofrequency hyperthermia improves progression-free survival rates. Overall survival rates also tended to increase. Given the absence of severe complications, it is necessary to continue research to achieve statistically significant results.
