PURPOSE: To determine the expression level, associations and biological role of PD-L1, IDO-1 and B7-H4 in non-small cell lung cancer (NSCLC). EXPERIMENTAL DESIGN: Using multiplexed quantitative immunofluorescence (QIF), we measured the levels of PD-L1, IDO-1, B7-H4 and different tumor infiltrating lymphoycte (TIL) subsets in 552 stages I-IV lung carcinomas from 2 independent populations. Associations between the marker levels, TILs and major clinico-pathological variables were determined...

BACKGROUND: Although epidermal growth factor receptor tyrosine kinase inhibitors (EGFR TKIs) have become the standard care of patients with advanced EGFR-mutant non-small cell lung cancer (NSCLC), development of acquired resistance is inevitable. A secondary mutation of threonine 790 (T790M) is associated with approximately half of the cases of acquired resistance. Strategies or agents to overcome this type of resistance are still limited. In this study, enhanced antitumor effect of AT-101, a-pan-Bcl-2 inhibitor, on gefitinib was explored in NSCLC with T790M mutation...

BACKGROUND: Focal adhesion kinase (FAK) is overexpressed in many types of tumours, including lung cancer. Y15, a small molecule which inhibits Y397 FAK autophosphorylation, decreases growth of human neuroblastoma, breast and pancreatic cancers. In this study, we investigated the in vitro and in vivo effects of Y15, and the underlying mechanism on non-small cell lung cancer cells. METHODS: The cytotoxic effects of Y15 targeting FAK signalling were evaluated. Gene-knockdown experiments were performed to determine the anti-cancer mechanism...

In the past decade major advances in tumor immunology, a better understanding of antigen recognition by T-cells likewise discovering the regulatory inhibitory signals resulted in the development of new immunotherapies with promising durable responses in various solid tumor types and in hematologic malignancies. This review focuses on immunomodulatory antibodies, namely immune checkpoint inhibitor therapy. The prototype of this new class of immune stimulating agents was cytotoxic T-lymphocyte antigen-4 (CTLA-4) antagonists...

Mutations in the epidermal growth factor receptor (EGFR) gene are associated with subsets of non-small cell lung cancer (NSCLC). Some patients with EGFR mutations are responsive to targeted therapy with the EGFR tyrosine kinase inhibitor gefitinib. Here, the mutation status of EGFR was assessed in advanced-stage NSCLC patients to determine how mutation status influences the clinical efficacy of gefitinib. The study included 106 patients with advanced NSCLC who were treated with gefitinib. Exons 19 and 21 of EGFR were sequenced from tumor tissues samples by PCR, and patient clinical characteristics, short-term outcomes (partial response, stable disease, progressive disease), and survival [overall survival (OS) and progression-free survival (PFS)] were compared...

PURPOSE: A crucial event in lung adenocarcinoma progression is the switch from an aerogenous spread toward an infiltrating tumor. Loss of RhoB expression has been suggested to be critical for lung cancer invasion. Here, we tested RhoB expression as a prognostic biomarker in non-small cell lung cancer (NSCLC) with a special focus on lepidic pattern. EXPERIMENTAL DESIGN: We analyzed RhoB expression using both IHC and RT-qPCR in two series of operated patients (n = 100 and 48, respectively) and in a series of advanced lepidic adenocarcinoma (n = 31) from different hospitals...

Boron Neutron Capture Therapy (BNCT) is a radiotherapy that combines biological targeting and high LET radiation. It consists in the enrichment of tumour with (10)B and in the successive irradiation of the target with low energy neutrons producing charged particles that mainly cause non-repairable damages to the cells. The feasibility to treat Non Small Cells Lung Cancer (NSCLC) with BNCT was explored. This paper proposes a new approach to determine treatment plans, introducing the possibility to choose the irradiation start and duration to maximize the tumour dose...

INTRODUCTION: Focal adhesion kinase (FAK) plays a significant role in cancer cell survival signaling and is overexpressed in various malignancies, including lung cancer. Previous studies suggest that FAK overexpression is an independent factor predicting poor prognosis in non-small-cell lung cancer (NSCLC). The aim of this study is to confirm these findings specifically in stage I NSCLC. METHODS: A retrospective tissue microarray (TMA) analysis of FAK protein expression by immunohistochemistry was performed in 157 surgically resected stage I NSCLC specimen and in the corresponding matched normal lung tissue...

The RAS/RAF/MEK/ ERK and the PI3K/AKT/mTOR pathways govern fundamental physiological processes, such as cell proliferation, differentiation, metabolism, cytoskeleton reorganization and cell death and survival. Constitutive activation of these signal transduction pathways is a required hallmark of cancer and dysregulation, on either genetic or epigenetic grounds, of these pathways has been implicated in the initiation, progression and metastastic spread of lung cances. Targeting components of the MAPK and PI3K cascades is thus an attractive strategy in the development of novel therapeutic approaches to treat lung cancer, although the use of single pathway inhibitors has met with limited clinical success so far...

Caveolin-1 (cav-1) has been implicated in the development of human cancers. However, the distribution of cav-1 in non-small cell lung cancer (NSCLC) and its significance require further study. Real-time PCR and Western blot assays were performed to detect cav-1 mRNA and protein levels in tumor tissues (TT) and matched tumor-free tissues (TF). The protein expression in 115 paraffin-embedded blocks was examined by immunohistochemical staining (IHC). Correlations between cav-1 mRNA and protein expression by IHC and clinicopathological features were statistically evaluated...

PURPOSE: No biologic signature of chemoradiotherapy sensitivity has been reported for patients with locally advanced non-small-cell lung cancer (NSCLC). We have previously demonstrated that basic fibroblast growth factor (FGF-2) and alphavbeta3 integrin pathways control tumor radioresistance. We investigated whether the expression of the proteins involved in these pathways might be associated with the response to treatment and, therefore, the clinical outcome. METHODS AND MATERIALS: FGF-2, beta3 integrin, angiopoietin-2, and syndecan-1 expression was studied using immunohistochemistry performed on biopsies obtained, before any treatment, from 65 patients exclusively treated with chemoradiotherapy for locally advanced NSCLC...

According to the recent data lung cancer in Czech republic is the most common malignancy in men (incidence 93/100 000) and is the leading cause of cancer death in men (mortality 90/100 000). In women is the incidence of lung cancer 30/100 000. Non-small-cell lung cancer (NSCLC) accounts for 70% to 75% of all lung cancers, while small-cell lung cancer (SCLC) accounts for 25% to 30% of cases. These two types of lung cance have a different biological characteristics which leads to a different approach in the treatment of NSCLC and SCLC...
