Fluorodeoxyglucose positron emission tomography and tumor marker expression in non-small cell lung cancer (original) (raw)

The Journal of thoracic and cardiovascular surgery, 2009

Abstract

The best current noninvasive surrogate for tumor biology is fluorodeoxyglucose positron emission tomography (FDG-PET). Both FDG-PET maximal standardized uptake values and selected tumor markers have been shown to correlate with stage, nodal disease, and survival in non-small cell lung cancer (NSCLC). However, there are limited data correlating FDG-PET with tumor markers. The purpose of this study was to determine the correlation of tumor marker expression with FDG-PET maximal standardized uptake values in NSCLC. FDG-PET maximal standardized uptake values were calculated in patients with NSCLC (n = 149). No patient had induction chemoradiotherapy. Intraoperative NSCLC tissue was obtained and tissue microarrays were created. Immunohistochemical analysis was performed for 5 known NSCLC tumor markers (glucose transporter 1, p53, cyclin D1, epidermal growth factor receptor, and vascular endothelial growth factor). Each tumor marker was assessed independently by two pathologists using com...
