6 MAPS trial conclusions Adding bevacizumab 15 mg/kg to Pemetrexed cispla n doublet significantly increased both PFS (by 2 months) andos(by 2.75 months) at the cost of a slight, manageable increase of toxicity; QOL was preserved in both arms and beva did not show a detrimental effect on QOL, despite the higher toxicity. In this study, standard arm patients had a longer OS than historical series, or patients in previous trials, possibly because of eligibility criteriafor bevacizumab The triplet Pemetrexed, cisplatin and bevacizumab is a new treatment paradigm for pleural mesothelioma patients eligible for bevacizumab, not amenable to curative surgery Statistical Group F.
