The numerical benefit in terms of overall survival in this study was 1.4 months; the authors of an accompanying Comment note that this is a small difference in a population with relatively good prognostic features (all had an ECOG performance status of 0 or 1 and 60% were aged <60 years). They say that in the absence of a predictive biomarker, it is not known which patients will benefit from treatment with ramucirumab.
