Longitudinal analysis of quality of life following treatment with asunercept plus reirradiation versus reirradiation in progressive glioblastoma patients.
2022 Background: Palliation of symptoms and the maintenance of quality of life (QoL) are important goals in cancer treatment.1,2 Beyond progression free survival (PFS) and overall survival (OS), health related QoL was one of the secondary endpoints in the asunercept plus irradiation Phase II trial (NCT01071837) in recurrent glioblastoma.3 Current analysis presents time to deterioration (TtD) of QoL using data from this study. Methods: Data from patients (pts) with a baseline and ≥1 post-baseline QoL assessment were included in this analysis. TtD was defined as the time from randomization to the first deterioration in the EORTC QLQ-C15, PAL EORTC QLQ-BN20 and Medical Research Council (MRC)-Neurological status. Deterioration was defined as a decrease of ≥10 points from baseline in the QLQ-C15 PAL overall QoL and functioning scales, an increase of ≥10 points from baseline in the QLQ-C15 PAL fatigue scale and the QLQ-BN20 total sum of score, and a rating of “Worse” in the MRC-Neurological status. Pts without a deterioration were censored at the last QoL assessment. Kaplan-Meier estimates were used to describe TtD and both treatment groups compared using the logrank test. The relationship between progression of disease (PD) and QoL deterioration has been investigated. Results: Compared to reirradiation alone, treatment with asunercept + reirradiation was associated with significant improvement of TtD (P≤0.01; Table). PD was a key driver for QoL deterioration and the median TtD was comparable with PFS in favour of the asunercept treatment arm. Conclusions: Treatment with asunercept plus irradiation significantly prolongs TtD and maintains QoL, versus reirradiation alone in progressive glioblastoma patients.
