Analysis of the prognostic impact of Treg-related genes in tumor and stroma in resectable NSCLC
2013
11073 Background: Immunosuppressive regulatory T lymphocytes (Tregs) have been proved to play a critical role in immune tolerance to tumor. In this study we have analyzed the expression of 11 genes related to Tregs in both tumor and stroma samples of resectable NSCLC patients. Methods: Primary tumor tissues of FFPE samples from 125 early-stage NSCLC patients were used in this retrospective study. The most representative areas of tumor cells and tumor stroma of each sample were carefully micro-dissected. RTqPCR using hydrolysis probes (TaqMan, Applied Biosystems) was performed to assess the expression of Treg markers such as: CD127, CD25, FOXP3, CTLA-4, IL-10, TGFB-1, LAG-3, GITR and TNF-a …
Ratios between VEGF ligands and receptors in tumor and stroma have impact on the outcome in resectable NSCLC.

e22147 Background: In tumor angiogenesis there is a complex interplay between endothelial, stromal and tumor cells. Some key regulators of this process are the members of the vascular endothelial growth factor (VEGF) family of ligands and receptors and the neuropilins (NRP). This study analyzes the correlations between the expression of these angiogenic factors in tumor cells and tumor stroma, and their prognostic role in tissue samples from resected non-small cell lung cancer (NSCLC) patients. Methods: Representative tumor and stroma areas from FFPE tissue samples of 125 early-stage NSCLC patients were carefully micro-dissected. RNA isolated from the samples was retrotranscripted and prea…
