ERCC1 mRNA Expression Is Not Associated with Response and Survival after Platinum-Based Chemotherapy Regimens in Advanced Non-Small Cell Lung Cancer Richard Booton, PhD, MRCP, Tim Ward, PhD, Linda Ashcroft, BSc, Julie Morris, PhD, Jim Heighway, PhD, Nick Thatcher, PhD, FRCP Journal of Thoracic Oncology Volume 2, Issue 10, Pages (October 2007) DOI: /JTO.0b013e318155a637 Copyright © 2007 International Association for the Study of Lung Cancer Terms and Conditions

FIGURE 1 Polymerase chain reaction efficiency in fresh frozen tumor and paraffin-embedded tumor biopsies. A, Real-time polymerase chain reaction plot of cDNA derived from three fresh frozen lung cancer tissues for a number of genes. The differences in the curve gradients in exponential phase make direct comparison of gene expression data difficult without prior correction. B, Similar data from cDNA derived from archival sources. The number of successful reactions is limited by the archival source, threshold value generally occurs later, and polymerase chain reaction efficiency (curve gradient) remains problematic.

FIGURE 2 Kaplan-Meier survival curve of patients with non-small cell lung cancer according to median expression of ERCC1. No significant difference in median survival was demonstrated for patients receiving platinum-based chemotherapy (including docetaxel or mitomycin C/ifosfamide) according to level of ERCC1 mRNA expression.
