EML4-ALK gene fusion (inv2(p21p23)) of non-small cell lung cancer (NSCLC) predisposes to tyrosine kinase inhibitor treatment. One of the gold standard diagnostics is the dual color (DC) break-apart (BA) FISH technique, however, the unusual closeness of the involved genes has been suggested to raise likelihood of random co-localization (RCL) of signals. Although this is suspected to decrease sensitivity (often to as low as 40-70%), the exact level and effect of RCL has not been revealed thus far. Signal distances were analyzed to the 0...

The success of immune checkpoint inhibitors and the discovery of useful biomarkers to predict response to these agents has shifted much of the focus of personalized care for advanced non-small cell lung cancer towards harnessing the immune response. With further advancement, more effective immunotherapy options will emerge along with more useful biomarkers. For patients with advanced disease, minimally invasive techniques will remain most appropriate for acquisition of tissue. This is in contrast to default gold-standard large tissue specimens obtained through surgical resection...

Each of the pathological stages (I-IIIa) in which surgically resected non-small cell lung cancer patients are classified conceals hidden biological heterogeneity, manifested in heterogeneous outcomes within each stage. Thus, the finding of robust and precise molecular classifiers to assess individual patient risk is an unmet medical need. Here we identified and validated the clinical utility of a new prognostic signature based on three proteins (BRCA1, QKI and SLC2A1) to stratify early lung adenocarcinoma patients according to their risk of recurrence or death...

We are presenting a case of acrometastasis in a male patient with lung adenocarcinoma. Acrometastases accumulate for 0.1% of all metastatic bone lesions and can be the first manifestation of cancer in approximately 10% of cases. The main clinical manifestations are tenderness, intermittent pain, functional impairment, erythema, heat and swelling of the affected part. Lung cancer is the main primary malignancy which causes acrometastases. Although the lesions can be recognized in x-rays or CT scans, the gold standard for the diagnosis is MRI scan in which the full extension of the tumor can be evaluated...

Background: Invasive mediastinal lymph node staging is essential to resectable non-small cell lung cancer (NSCLC) patients. This retrospective study aimed to compare the diagnostic yield of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) against cervical mediastinoscopy (CMS) in radiologically enlarged mediastinal lymph nodes. Methods: Retrospective data were collected from January 2009 to March 2016. Suspected lung cancer patients with enlarged mediastinal lymph nodes (short axis ≥10 mm), underwent EBUS-TBNA or CMS for invasive mediastinal staging were enrolled...

BACKGROUND: The histological classification or subtyping of non-small cell lung cancer is essential for systematic therapy decisions. Differentiating between the two main subtypes of pulmonary adenocarcinoma and squamous cell carcinoma highlights the considerable differences that exist in the prognosis of patient outcomes. Physicians rely on a pathological analysis to reveal these phenotypic variations that requires invasive methods, such as biopsy and resection sample, but almost 70% of tumors are unresectable at the point of diagnosis...

BACKGROUND: Outcomes for patients in UK with locally advanced non-small cell lung cancer (LA NSCLC) are amongst the worst in Europe. Assessing outcomes is important for analysing the effectiveness of current practice. However, data quality is inconsistent and regular large scale analysis is challenging. This project investigates the use of routine healthcare datasets to determine progression free survival (PFS) and overall survival (OS) of patients treated with primary radical radiotherapy for LA NSCLC...

Background: Video-assisted thoracoscopic surgery (VATS) lobectomy has recently been adopted as the gold standard surgical option for the treatment of early stage non-small cell lung cancer. Enhanced recovery after surgery (ERAS) is being progressively adopted in thoracic surgery to improve the postoperative outcomes. Even if the benefits of ERAS are universally accepted, to date a standardized and uniform approach has not been described in the medical literature. The Italian VATS group has recently proposed to include in the VATS lobectomy database a structured protocol for ERAS...

Background: The incidental detection of solitary pulmonary nodule (SPN) is currently increasing due to the widespread use of computed tomography (CT) during the follow up in oncological patients or in screening trials. A quick and definitive histological diagnosis of these nodes is mandatory as, in case of primitive lung cancer, an early detection could improve both surgical results and prognosis. The minimally invasive pulmonary resection (MIPR) is the gold standard procedure for diagnosis and treatment of small lung nodules, but it can be difficult to localize deep nonpalpable nodes that lie in the lung parenchyma...

Purpose: About 60% of non-small cell lung cancer (NSCLC) patients develop resistance to targeted epidermal growth factor receptor (EGFR) inhibitor therapy through the EGFR T790M mutation. Patients with this mutation respond well to third-generation tyrosine kinase inhibitors, but obtaining a tissue biopsy to confirm the mutation poses risks and is often not feasible. Liquid biopsies using circulating free tumor DNA (cfDNA) have emerged as a noninvasive option to detect the mutation; however, sensitivity is low as many patients have too few detectable copies in circulation...

Introduction: Invasive' pulmonary aspergillosis (IPA) has been one of the major causes of mortality in immunocompromised patients. The gold standard method for a diagnosis of IPA is histopathological examination of the lung tissue; however, post-procedural bleeding limits the feasibility of lung biopsy. The European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and The National Institute of Allergy and Infectious Disease Mycoses Study Group (EORTC/MSG) defined IPA...

BACKGROUND: DNA methylation is a stable form of epigenetic memory used by cells to control gene expression. Whole genome bisulfite sequencing (WGBS) has emerged as a gold-standard experimental technique for studying DNA methylation by producing high resolution genome-wide methylation profiles. Statistical modeling and analysis is employed to computationally extract and quantify information from these profiles in an effort to identify regions of the genome that demonstrate crucial or aberrant epigenetic behavior...

Non-islet cell tumor hypoglycemia (NICTH) is a rare paraneoplastic condition caused most commonly by metastatic mesenchymal tumors. A 74-year-old non-diabetic male with an eight-year history of metastatic sarcomatoid lung cancer presented with altered mental status. His previous treatment included a lobectomy and radiation. Laboratory investigations were significant for blood glucose of 28 mg/dL, confirming hypoglycemia. He was hypokalemic, a condition seen in approximately 50% of patients with NICTH, at 2...

BACKGROUND: Mediastinoscopy is considered the gold standard for preresectional staging of lung cancer. We sought to examine the effect of concomitant mediastinoscopy on postoperative pneumonia (POP) in patients undergoing lobectomy. METHODS: All patients in our institutional database (2008-2015) undergoing lobectomy who did not receive neoadjuvant therapy were included in our study. The relationship between mediastinoscopy and POP was examined using univariate (Chi square) and multivariate analyses (binary logistic regression)...

Despite efforts, brain metastases (BM) remain a critical issue in the management of patients affected by non-small-cell lung cancer (NSCLC). To date, radiotherapy is still considered the gold standard treatment; on the other hand, systemic chemotherapeutical agents are not so often an effective therapy for BM, whereas targeted agents in oncogene-addicted disease have shown a good activity also on BM. Anti-programmed death-1/programmed death ligand-1 agents represent a new valid therapeutic strategy for NSCLC as well as for several tumor types, but their efficacy on patients with BM is still unclear mainly due to the strict selection criteria adopted in clinical trials...

Molecular profiling has changed the treatment landscape in advanced non-small-cell lung cancer. Accurately identifying the tumours that harbour sensitizing EGFR mutations, the most common targetable molecular alteration, as well as those with acquired resistance mutations (e.g. T790M) on treatment is a high clinical priority. The current clinical gold standard is genotyping of tumour specimens. However, the practical utility of this approach is limited by the lack of available tissue and the potential complications associated with biopsies...

Bronchus sleeve resection for operative treatment of non-small cell lung cancer (NSCLC) is a gold standard in modern thoracic surgery in cases of centrally located tumors or hilär lymph node metastases. Advanced instruments and growing surgical experience allowed surgeons to reduce the required incisions (from 3-port to uniportal) and to resect larger and more centrally located malignancies minimal invasively. It is a logical and expected advance in thoracic surgery that video-assisted thoracoscopic surgery (VATS) would be ultimately used also for complex bronchial resections...

Chemotherapy-induced lung toxicity can affect pulmonary parenchyma, pleura, airways, pulmonary vascular system, mediastinum or the neuromuscular system that is responsible for respiration. Chemotherapy-induced pulmonary toxicity is a diagnosis of exclusion. When the patients with malignancies develop pulmonary toxicity such as pneumonitis and distinguishing it from alternative diseases such as infectious, thrombotic, cardiac, malignant or exacerbation of chronic lung conditions can be difficult. Moreover, such patients are often immunosuppressed, physically stressed from the underlying disease and the cancer treatment and hence, more susceptible to usual and unusual or opportunistic infections...
