Fig 1 Representative examples of marker expression in tumor cohort. (EGFR = epidermal growth factor receptor; p-AKT = phosphorylated murine thymoma viral oncogene homolog; PTEN = phosphatase and tensin homolog; p-ERK = phosphorylated extracellular signal related kinase.)

Fig 3 Overall survival and disease-free interval analyses by epidermal growth factor receptor status. The cumulative number of patients at risk (N at Risk) by year is represented by positive (pos) and negative (neg) immunophenotype status. Crosshatch marks represent censured data points. (A, B) OS and DFI for all tumors (median follow-up 73.0 and 31.5 months, respectively); (C, D) OS and DFI for BAC (median follow-up 49.1 and 25.7 months, respectively); (E, F) OS and DFI for adeno/BAC (median follow-up 81.5 and 45.3 months, respectively). (OS = overall survival; DFI = disease free interval; EGFR = epidermal growth factor receptor; BAC = bronchioloalveolar carcinoma; adeno/BAC = adenocarcinoma, mixed subtype, with bronchioloalveolar components.)
