ABSTRACT
Objective To investigate clinical efficacy of simultaneous integrate boost for glioblastoma with intensity?modulated radiotherapy ( SIB?IMRT). Methods A total of 46 patients with glioblastoma who underwents SIB?IMRT from January 2013 to August 2014,were retrospectively analyzed. Toxicity after completion of SIB?IMRT were assessed. Kaplan?Meier method was used to analyze survival and progression?free survival. Multivariate analyses were performed to determine significant prognostic factors. Results There was no patients delayed by more than grade 3 radiation toxicity. The median overall survival and 1?year survival rates was 69 weeks and 73%,respectively. The progression free survival and 1?year progression?free survival rate were 43 weeks and 39%,respectively. The pattern of failure was identical (9 Local, 7 distant and 0 marginal recurrence). Multivariate analyses show that temozolomide concurrent chemoradiotherapy were independent factors correlated to prognosis. Conclusions The preliminary results demonstrate that SIB?IMRT for glioblastoma appear to be effective and safe. With the limted number of patients in this group,SIB?IMRT could be used for treating glioblastoma with caution,which deserves further study.
