Abstract 5345


New therapies aimed at activation of T and NK cells expand NSCLC treatments options. It is conceivable that markers designating ‘immune ignorant’, ‘immune excluding’ or ‘inflamed’ tumor phenotypes may influence the effectiveness of specific immune therapies.


qRT-PCR was used to assess the levels of 48 mRNAs in frozen tumor tissue sections from 115 stage I-IIIA NSCLC patients (33% never-smokers, 75% lung adenocarcinoma) who underwent pulmonary resection, and in matched normal lung parenchyma. mRNA expression (normalized vs. 4 reference genes) was compared between groups that did (45%) and did not relapse.


Low expression of TIGIT (p.adj=0.031) and CTLA4 (p.adj=0.048) was correlated with shorter distant metastasis free survival after correction for multiple comparisons. In the subset of 75 lung adenocarcinoma cases, low expression of TIGIT, NCR3, CXCR3, FASLG, CD96, CTLA4, PD1, FYB and FOXP3 was correlated with shorter distant metastasis free survival after correction for multiple comparisons (p.adj


Non-inflamed NSCLC phenotype is associated with higher risk of distant metastases in early stage NSCLC. The non-inflamed phenotype is accompanied by lower expression of chemoattractants for lymphocytes. Expression of immune tolerance markers is increased in NSCLC compared to normal lung tissues.
