Abbreviations: COSMIC=Catalogue of Somatic Mutations in Cancer; QC=quality control. Mutations described in COSMIC and potentially targetable by a drug in early-phase trials were considered ‘actionable'. Values above represent % of samples analysed which harboured a mutation known to impact the pathways described.
