ABSTRACT
The optimal end point for phase II studies for recurrent glioblastoma (GBM) is unclear and a matter of debate. Moreover, data about post-progression survival (PPS) after the first disease progression in GBM patients treated according to EORTC 26981/22981/NCIC CE.3 trial are limited. The aim of this study was to evaluate the PPS in GBM patients. The analysis was made with a database on 1,006 GBM patients followed prospectively between 06/2005 and 06/2010. Eligibility criteria for the study were: age ≥18 years; PS: 0-2; chemotherapy given at disease progression after RT/TMZ. 232 patients (mean age 52 years, range 18-77 years) were enrolled. The median PFS following second line chemotherapy (PFS2) was 2.5 months (95 % CI 2.1-2.9) and the rate of patients free of progression at 6 months (PFS2-6 mo), was 21.6 % (95 % CI 16.3-26.9 %). The median PPS was 8.6 months (95 % CI 7.4-9.8), PPS rates were: PPS-6: 66 % (95 % CI 60.3-72.9 %), PPS-9: 48.2 % (95 % CI 41.5-54.9 %) and PPS-12: 31.7 % (95 % CI 25.2-38.2 %). PPS in unselected patients treated with alkylating agents is about 8 months. PPS rates could be of interest as an end point in future studies in recurrent GBM.
