Abstract |
The aim of this study is to examine the relationship between the expression level of excision repair cross-complementation group 1 (ERCC1) and of 2-[18F]-fluoro- 2-deoxy-D-glucose (18F-FDG) positron emission tomography (PET) in various thoracic neoplasm.Three hundreds-eight patients [ non-small cell lung cancer (NSCLC)(n=56), malignant pleural mesothelioma (MPM)(n=21), pulmonary metastatic tumors (PMT)(n=148), thymic epithelial tumors (n=49) and pulmonary neuroendocrine tumor (n=34)] who underwent 18F-FDG PET before treatment were included in this study. Tumors sections were stained by immunohistochemistry for ERCC1, glucose transporter 1(Glut1), vascular endothelial growth factor ( VEGF) and microvessel density (MVD) by determinate by CD34. The expression of ERCC1 in thoracic neoplasms had a positivity of 49% (152/308), and the positive rates of ERCC1 expression in NSCLC, PMT, thymic epithelial tumor, pulmonary neuroendocrine tumor and MPM were 52, 43, 53, 47 and 85%, respectively. The positivity of ERCC1 expression was significantly higher in MPM and SQC than in the other histological types. A statistically significant correlation between ERCC1 expression and 18F-FDG uptake was observed in thymic epithelial tumors, especially thymoma. Moreover, ERCC1 expression was also closely associated with the expression of Glut1, VEGF and MVD.Our results indicated that 18F-FDG uptake may be an alternative biomarker for predicting ERCC1 expression in patients with thymoma.
