Association of PALB2Messenger RNA Expression with Platinum-Docetaxel Efficacy in Advanced Non–Small Cell Lung Cancer

Partner and localizer of BRCA2 (PALB2) is essential for homologous recombination repair. We examined mRNA levels of DNA repair genes, including partner and localizer of BRCA2 gene (PALB2), ring finger protein 8 gene (RNF8),replication timing regulatory factor 1 gene (RIF1),ATM serine/threonine kinase gene (ATM), and tumor protein p53 binding protein 1 gene (53BP1) as predictive biomarkers for cisplatin-docetaxel in the European phase III BRCA1, DNA repair associated (BRCA1)–receptor-associated protein 80 (RAP80) expression customization (BREC) phase III clinical trial (ClinicalTrials.govidentifier NCT00617656).
