The IFCT-GFPC-0701 MAPS Phase III trial highlighted significant improvement in overall survival from adding bevacizumab to the standard first-line chemotherapy regimen (cisplatin plus pemetrexed (PC)), in advanced malignant pleural mesothelioma (MPM). We present the results of health-related quality of life (HRQoL), a secondary endpoint of MAPS.
HRQoL was assessed using the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire QLQ-C30 and the Lung Cancer specific module QLQ-LC13 at randomization and then every 9 weeks until disease progression. HRQoL deterioration-free survival (QFS), used to analyze longitudinal HRQoL data, was defined as the interval between randomization and the occurrence of the first clinically relevant definitive deterioration compared to the HRQoL score at baseline, or death.
A total of 448 patients were included in the MAPS trial between 2008 and 2014. At baseline, 425 patients (94.8%) completed the HRQoL questionnaire. We report that adding bevacizumab to cisplatin and pemetrexed (PCB) significantly improved QFS for the peripheral neuropathy dimension with a 12.09 months median QFS (95% confidence interval [CI] 9.59-13.67) in the PCB arm versus 7.59 months (95%CI 6.57-8.61) in the PC arm (HR [PCB vs. PC]=0.74, 95%CI 0.61-0.91, p=0.004). QFS was also longer in the PCB arm for the pain dimension (HR=0.84, 95% CI 0.69-1.02; p=0.08). Conclusions This study demonstrated that adding bevacizumab to standard chemotherapy in patients with advanced MPM had no negative impact on HRQoL. A significant improvement in the peripheral neuropathy and pain HRQoL dimensions was even observed.
