BACKGROUND: The proportion of never-smokers with non-small cell lung cancer (NSCLC) is increasing, but that in Korea has not been well addressed in a large population. We aimed to evaluate the proportion and clinical features of never-smokers with NSCLC in a large single institution. METHODS: We analyzed clinical data of 1860 consecutive patients who were newly diagnosed with NSCLC between June 2011 and December 2014. RESULTS: Of the 1860 NSCLC patients, 707 (38...

Specific oncogenes with driver mutations, such as the Epidermal Growth Factor Receptor (EGFR 1) gene can lead to non-small-cell lung cancer formation. Identification of these oncogenes, their driver mutations and downstream effects allow the targeting of these pathways by drugs. Such personalised therapy has become an important strategy in combating lung cancer and highlights the need to test for these mutations. Tyrosine Kinase Inhibitors (TKIs) against EGFR, such as Erlotinib, are able to halt these tumour promoting properties in non-small-cell lung cancers...

Non-small-cell lung cancer (NSCLC) is one of the leading causes of cancer deaths, both within the US and worldwide. There have been major treatment advances in NSCLC over the past decade with the discovery of molecular drivers of NSCLC, which has ushered in an era of personalized medicine. There are several actionable genetic aberrations in NSCLC, such as epidermal growth factor receptor and anaplastic lymphoma kinase (ALK). In 3%-7% of NSCLC, a chromosomal inversion event in chromosome 2 leads to fusion of a portion of the ALK gene with the echinoderm microtubule-associated protein-like 4 (EML4) gene...

The presence of activating mutations of the epidermal growth factor receptor (EGFR) is predictive of response to first- and second-generation tyrosine kinase inhibitors (TKIs) in patients with advanced non-small-cell lung cancer (NSCLC). However, patients that initially respond to these drugs inexorably become resistant. The T790M mutation in the exon 20 of the EGFR is the main mechanism of resistance to EGFR TKIs occurring in over 50% of the cases. Third generation EGFR TKIs have been shown to be active in patients who progressed after TKI treatment and carry the T790M mutation...

BACKGROUND: Lung cancer seems to have different epidemiological, biomolecular and clinical characteristics in females than in males, with a better prognosis for women. The aim of the study is to determine gender differences in lung adenocarcinoma in terms of androgen (AR), estrogen (ER)α and progesterone (PgR) receptors expression and their impact on outcome. RESULTS: Overall survival was significantly better in ERα and in PgR positive lung adenocarcinoma patients (median survival 45 vs...

BACKGROUND: Lung adenocarcinoma (AD) is a common variant of non-small cell lung cancer (NSCLC). Programmed cell death protein 1/programmed cell death ligand 1 (PD1/PD-L1) are promising immunotherapy targets and its expression may be an important biomarker of predicting clinical response. In this study, we evaluated PD-L1 expression in conjunction with clinicopathological characteristics and outcomes in resected lung adenocarcinoma. RESULTS: This study included 133 cases of lung adenocarcinoma...

Lung squamous cell carcinoma is a common type of lung cancer, causing approximately 400,000 deaths per year worldwide. Genomic alterations in squamous cell lung cancers have not been comprehensively characterized, and no molecularly targeted agents have been specifically developed for its treatment. As part of The Cancer Genome Atlas, here we profile 178 lung squamous cell carcinomas to provide a comprehensive landscape of genomic and epigenomic alterations. We show that the tumour type is characterized by complex genomic alterations, with a mean of 360 exonic mutations, 165 genomic rearrangements, and 323 segments of copy number alteration per tumour...

PURPOSE OF REVIEW: The concept of mutually exclusive oncogenic driver alterations has prevailed over the past decade, but recent reports have stressed the possible occurrence of dual-positive non-small-cell lung cancer (NSCLC) and even triple-positive disease for these oncogenes. This entity presents novel prognostic and therapeutic challenges. The present review highlights the available data in an effort to clarify the clinical and pathological significance of coexisting mutations as well as the subsequent therapeutic consequences...

We report a rare case of an incidental diagnosis of necrotizing sarcoid granulomatosis (NSG) in a 60-y-old non-smoking male. The patient was admitted to the hospital for sudden back pain. Chest x-ray revealed areas of parenchymal consolidation and high-resolution computed tomography demonstrated a pulmonary nodular pattern with no lymph node enlargement. All laboratory and pulmonary function tests were normal. Bronchoscopy with bronchoalveolar lavage showed no sign of infection or specific inflammation. The diagnosis of NSG was made by histopathological examination of a surgical lung biopsy and by excluding other causes of granulomatous disease...

Necrotizing granulomas are commonly encountered in surgically resected specimens. The majority will be proven infectious with special stains for microorganisms. These need to be distinguished from other granulomatous processes such as Wegener's granulomatosis (WG). Although there may be histological overlap between these different processes, the identification of a true necrotizing vasculitis is specific to WG in the context of necrotizing granulomas. Otherwise, the combination of histological features should lead to a specific diagnosis...

Advanced stage nonsmall cell lung cancer had been treated mainly with platinum-based doublet chemotherapy, and other cytotoxic agents that offered significant survival advantage over best supportive care, until recently. Modest improvements were achieved with the addition of antibodies targeting the vascular endothelial growth factor, and the introduction of maintenance chemotherapy. Improvements in our knowledge of lung cancer biology have shifted the current treatment paradigm from being based on histology to one based on molecular biomarkers...

Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive interstitial lung disease of unknown cause. IPF has a distinct histopathological pattern of usual interstitial pneumonia in which fibroblastic foci (FF) represent the leading edge of fibrotic destruction of the lung. Currently there are three major hypotheses for how FF are generated: (1) from resident fibroblasts, (2) from bone marrow-derived progenitors of fibroblasts, and (3) from alveolar epithelial cells that have undergone epithelial-mesenchymal transition (EMT)...

Background Osimertinib is an epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) that is selective for both EGFR-TKI sensitizing and T790M resistance mutations in patients with non-small-cell lung cancer. The efficacy of osimertinib as compared with platinum-based therapy plus pemetrexed in such patients is unknown. Methods In this randomized, international, open-label, phase 3 trial, we assigned 419 patients with T790M-positive advanced non-small-cell lung cancer, who had disease progression after first-line EGFR-TKI therapy, in a 2:1 ratio to receive either oral osimertinib (at a dose of 80 mg once daily) or intravenous pemetrexed (500 mg per square meter of body-surface area) plus either carboplatin (target area under the curve, 5 [AUC5]) or cisplatin (75 mg per square meter) every 3 weeks for up to six cycles; maintenance pemetrexed was allowed...

Cancer treatment is evolving towards therapies targeted at specific molecular abnormalities that drive tumor growth. Consequently, to determine which patients are eligible, accurate assessment of molecular aberrations within tumors is required. Obtaining sufficient tumor tissue for molecular testing can present challenges; therefore, circulating free tumor-derived DNA (ctDNA) found in blood plasma has been proposed as an alternative source of tumor DNA. The diagnostic utility of ctDNA for the detection of epidermal growth factor receptor (EGFR) mutations harbored in tumors of patients with advanced non-small-cell lung cancer (NSCLC) is supported by the results of several large studies/meta-analyses...

The advent of genomic based personalized medicine has led to multiple advances in the molecular characterization of many tumor types, such as non-small cell lung cancer (NSCLC). NSCLC is diagnosed in most cases on small tissue samples that may be not always sufficient for EGFR mutational assessment to select patients for first and second generations' tyrosine kinase inhibitors (TKIs) therapy. In patients without tissue availability at presentation, the analysis of cell free DNA (cfDNA) derived from liquid biopsy samples, in particular from plasma, represent an established alternative to provide EGFR mutational testing for treatment decision making...

The present study describes the case of a 45-year-old man diagnosed with metastatic lung adenocarcinoma, which harbored a deletion within exon 19 of the epidermal growth factor receptor (EGFR) gene. The patient was subsequently treated with gefitinib (250 mg/day orally from May 2013 to March 2014), but developed acquired resistance to the drug following 11 months of treatment. Tumor burden molecular analysis was performed on a tumor rebiopsy and plasma sample, and histological analysis was also performed on the tumor rebiopsy...

The usual treatments for patients with non-small-cell lung cancer (NSCLC), such as advanced lung adenocarcinoma, are unspecific and aggressive, and include lung resection, radiotherapy and chemotherapy. Recently, treatment with monoclonal antibodies and biological inhibitors has emerged as an effective alternative, generating effective results with few side effects. In recent years, several clinical trials using monoclonal antibodies presented potential benefits to NSCLC, and four of them are already approved for the treatment of NSCLC, such as cetuximab, bevacizumab, nivolumab and pembrolizumab...

Despite the improvement in clinical outcomes derived by the introduction of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (EGFR-TKIs) in the treatment of patients with advanced non-small cell lung cancer (NSCLC) whose tumours harbour EGFR-activating mutations, prognosis remains unfavourable because of the occurrence of either intrinsic or acquired resistance. We reviewed the published literature and abstracts of oral and poster presentations from international conferences addressing EGFR-TKIs resistance mechanisms discovered in preclinical models and in patients with NSCLC...
