BACKGROUND: Nivolumab is approved worldwide as second-line treatment for metastatic non-small cell lung cancer (NSCLC). Despite the fact that most of these cancers are being diagnosed in the older patients, few of the patients were included in pivotal trials. We aimed to describe efficacy and safety in a "real-world" older population. PATIENTS AND METHODS: We retrospectively collected data from older patients (≥70 years old) with advanced or metastatic NSCLC treated with Nivolumab in our institution...

Stereotactic radiosurgery (SRS) using the Gamma Knife (GK) is now being increasingly utilized for the treatment of brain metastases. However, there are a few reported cases of SRS-induced brain neoplasms. We herein report the case of a Japanese woman with metastatic non-small cell lung cancer (NSCLC) harboring EGFR-mutations who was treated four times with a GK for brain metastases. She developed glioblastoma 5.7 years after the initial GK surgery. Radiation-induced secondary neoplasms generally appear after a latency period of several years...

Immunotherapy targeting the programmed cell death-1/programmed death ligand 1(PD-L1) pathway has shown promising antitumor activity in brain metastases (BMs) of non-small cell lung cancer (NSCLC) patients with an acceptable safety profile; however, the response rates often differ between primary lesions and intracranial lesions. Studies are necessary to identify detailed characterizations of the response biomarkers. In this study, we aimed to compare the differences of PD-L1 expression and CD8+ tumor-infiltrating lymphocyte (TIL) density, two major response biomarkers of PD-1/PD-L1 blockade, between paired primary and brain metastatic lesions in advanced NSCLC...

BACKGROUND: Recent studies evaluated the diagnostic accuracy of circulating tumor DNA (ctDNA) in the detection of epidermal growth factor receptor (EGFR) mutations from plasma of NSCLC patients, overall showing a high concordance as compared to standard tissue genotyping. However it is less clear if the location of metastatic site may influence the ability to identify EGFR mutations in plasma. OBJECTIVE: This pooled analysis aims to evaluate the association between the metastatic site location and the sensitivity of ctDNA analysis in detecting EGFR mutations in NSCLC patients...

Tumor heterogeneity and changes in epidermal growth factor receptor (EGFR) mutation status over time challenge the design of effective EGFR tyrosine kinase inhibitor (TKI) treatment strategies for non-small cell lung cancer (NSCLC). Therefore, there is an urgent need to develop techniques for comprehensive tumor EGFR profiling in real time, particularly in lung cancer precision medicine trials. We report a positron emission tomography (PET) tracer, N -(3-chloro-4-fluorophenyl)-7-(2-(2-(2-(2-18 F-fluoroethoxy) ethoxy) ethoxy) ethoxy)-6-methoxyquinazolin-4-amine (18 F-MPG), with high specificity to activating EGFR mutant kinase...

BACKGROUND: The prognosis of metastatic recurrent non-small cell lung cancer (NSCLC) is poor, and chemotherapy improves survival by only a few months. The concept of oligo-recurrence, defined as a small number of new lesions at a distant site theoretically curable by local therapy, has recently been proposed for several cancers. To evaluate the possible benefits of surgical resection for oligo-recurrence, we report the outcomes of seven patients who underwent hepatic resection for oligo-recurrence of NSCLC in the liver...

BACKGROUND/AIMS: Reversion-inducing cysteine-rich protein with kazal motifs (RECK) is a novel tumor suppressor gene that is critical for regulating tumor cell invasion and metastasis. The expression of RECK is dramatically down-regulated in human cancers. Harmine, a tricyclic compound from Peganum harmala, has been shown to have potential anti-cancer activity. METHODS: Cell proliferation assay (CCK-8 cell viability assay), cell cycle analysis (detection by flow cytometry), apoptosis staining assay (TUNEL staining), cell migration assay and invasion assay (transwell assay) were carried out to investigate the Harmine's efficacy on non-small cell lung cancer (NSCLC) cells in vitro...

BACKGROUND/AIMS: Recently, endothelial-like cells originating directly from tumor cells have been revealed. However, the mechanism remains unclear. ETS-1 (E26 transformation specific-1), a key transcription factor in the generation and maturation of ECs (endothelial cells), has been reported to be overexpressed in several cancers. Here, we reveal novel regulation of the endothelial-like differentiation of NSCLC (non-small cell lung cancer) cells by ETS-1. METHODS: We up-regulated the expression of ETS-1 in NSCLC cell lines by H2O2 or lentiviral vector...

BACKGROUND: Immune checkpoint inhibitors targeting the PD-L1 pathway have shown benefit for the treatment of metastatic non-small cell lung cancer (NSCLC). However, the prognostic value of PD-L1 independent of immunotherapy is still unclear, with conflicting results reported between PD-L1 expression and patient survival. Our aim was to correlate PD-L1 mRNA level with clinical and pathologic factors and to investigative the prognostic value of PD-L1 mRNA in all stages of NSCLC. METHODS: Gene expression and clinical data were obtained from public TCGA repositories from the National Cancer Institute...

Non-small cell lung cancers (NSCLC) harboring the uncommon epidermal growth factor receptor (EGFR) exon 20 insertion mutations are generally thought to be unresponsive to EGFR-tyrosine kinase inhibitor (TKI) therapy. Presented here is a case of stage IV NSCLC harboring an uncommon EGFR exon 20 insertion mutation that was maintained at minimal progressive disease for 54 months, with 36 months on the second-generation TKI afatinib. Contrary to the existing literature, the patient in this case demonstrated a long, durable response to the EGFR-TKI, which was exhibited by a long survival endpoint...

Background: Crizotinib has shown greater efficacy in clinical trials than chemotherapy in patients with anaplastic lymphoma kinase-positive (alk+) non-small cell lung cancer (nsclc), but little information is available on its use and outcomes in real-world settings. We therefore assessed treatment patterns and outcomes in alk+ nsclc patients treated with crizotinib in regular clinical practice. Methods: A retrospective medical record review was conducted in North America for adults with alk+ nsclc treated with crizotinib as first- or later-line therapy for metastatic disease between 1 August 2011 and 31 March 2013 (for the United States) or 1 May 2012 and 31 March 2013 (for Canada)...

Non-small-cell lung cancer (NSCLC) accounts for most lung cancer cases. Therapeutic interventions integrating the use of different agents that focus on different targets are needed to overcome this set of diseases. The proteasome system has been demonstrated clinically as a potent therapeutic target for haematological cancers. However, promising preclinical data in solid tumors are yet to be confirmed in clinics. Herein, the combinational use of Bortezomib (BZM) and 2-aminoethoxydiphenylborane (2-APB) toward NSCLC cells was studied...
