Epigenetic deregulation is increasingly being recognized as a hallmark of cancer. Recent studies have identified many new epigenetic biomarkers, some of which are being introduced into clinical practice for diagnosis, molecular classification, prognosis or prediction of response to therapies. O-6-methylguanine-DNA methyltransferase gene is the most clinically advanced epigenetic biomarker as it predicts the response to temozolomide and carmustine in gliomas. Therefore, epigenomics may represent a novel and promising tool for precision medicine, and in particular, the detection of epigenomic biomarkers in liquid biopsies will be of great interest for monitoring diseases in patients...

Breast cancer is highly heterogeneous and is classified into four subtypes characterized by specific biological traits, treatment responses, and clinical prognoses. We performed a systemic analysis of 698 breast cancer patient samples from The Cancer Genome Atlas project database. We identified 136 breast cancer genes differentially expressed among the four subtypes. Based on unsupervised clustering analysis, these 136 core genes efficiently categorized breast cancer patients into the appropriate subtypes. Functional enrichment based on Kyoto Encyclopedia of Genes and Genomes analysis identified six functional pathways regulated by these genes: JAK-STAT signaling, basal cell carcinoma, inflammatory mediator regulation of TRP channels, non-small cell lung cancer, glutamatergic synapse, and amyotrophic lateral sclerosis...

BACKGROUND: With the development of genetic mutations and targeted drugs, accurate therapy of lung adenocarcinoma attracts much more attention, and more research is focued on epidermal growth factor receptor (EGFR). It is unclear whether the result of EGFR mutation and pathology type is consistent with different specimens. In our study, by comparing the relationship between EGFR mutations and pathological classification of lung adenocarcinoma in surgical resection of specimen and biopsy specimen, to discuss the relationship between EGFR mutations and pathological classification of and the influence of specimen type on EGFR gene detection...

Introduction Pseudotumour of the lung is a collective term for various subentities. Some subgroups are considered to be intermediary malignant tumours. A pseudotumour is a rare condition, which makes it difficult to estimate its incidence and prevalence. Methods Retrospective analysis of all surgically treated patients between 2008 and 2015 diagnosed with a pseudotumour of the lung. The primary endpoint of this study was to estimate the rates of local recurrence and metastasis. Secondary endpoints were to determine the nomenclature, medical history, treatment, and the perioperative course...

GOAL: Chest auscultations offer a non-invasive and low-cost tool for monitoring lung disease. However, they present many shortcomings including inter-listener variability, subjectivity, and vulnerability to noise and distortions. The current work proposes a computer-aided approach to process lung signals acquired in the field under adverse noisy conditions, by improving the signal quality and offering automated iden- tification of abnormal auscultations indicative of respiratory pathologies...

Within the cohort of patients suffering from idiopathic pulmonary arterial hypertension (IPAH) is a group that responds dramatically (VR-PAH) to an acute vasodilator challenge and that has excellent long-term hemodynamic improvement and prognosis on high dose calcium channel blockers compared with vasodilator non-responders (VN-PAH). For the purposes of diagnosing VR-PAH, there is to date no test to replace the acute vasodilator challenge. However, recent studies have identified markers that may aid in the identification of VR-PAH, including peripheral blood lymphocyte RNA expression levels of desmogelin-2 and Ras homolog gene family member Q, and plasma levels of provirus integration site for Moloney murine leukemia virus...

Damage to the respiratory system worsens prognosis and increases mortality in all systemic immunoinflammatory rheumatic diseases (SIRDs). Leading pulmonary manifestations in each disease are different, so the typical picture of each nosological entity is very peculiar. In all SIRDs, the disease starts with lung involvement in 10-20% of cases, preceding the expanded clinical presentation of a systemic disease. At a certain stage, lung damage may be the only manifestation of the disease or predominate in its clinical picture, determining the severity of a condition...

Increasing evidence suggests that the glutathione peroxidase 2 may actually play important roles in tumorigenesis and progression in various human cancers such as colorectal carcinomas and lung adenocarcinomas. However, the role of glutathione peroxidase 2 in gastric carcinoma remains to be determined. In this study, the expression and prognostic significance of glutathione peroxidase 2 in gastric carcinoma were investigated and the well-known prognostic factor Ki-67 labeling index was also assessed as positive control...

Typical (TCs) and atypical carcinoids (ACs) are defined based on morphological criteria, and no grading system is currently accepted to further stratify these entities. The 2015 WHO classification restricts the Ki-67 role to biopsy or cytology samples, rather than for prognostic prediction. We aimed to investigate whether values and patterns of Ki-67 alone would allow for a clinically meaningful stratification of lung carcinoids, regardless of histological typing. Ki-67 proliferation index and pattern (homogeneous versus heterogeneous expression) were assessed in a cohort of 171 TCs and 68 ACs...

RATIONALE: Interstitial lung disease (ILD) is an important cause of morbidity and mortality in scleroderma (Scl). Risk prediction and prognostication in Scl-ILD patients is challenging because of heterogeneity in the disease course. METHODS: We aimed to develop a clinical mortality risk prediction model for Scl-ILD. Patients with Scl-ILD were identified from two ongoing longitudinal cohorts: 135 patients at the University of California, San Francisco (UCSF, derivation cohort) and 90 patients at the Mayo Clinic (validation cohort)...

INTRODUCTION: The aim of this study was to validate the new 8th edition of the tumor-node-metastasis (TNM) classification and to elucidate whether radiological solid size corresponds to pathological invasive size incorporated in this T factor. METHODS: We analyzed the data of 1792 patients who underwent complete resection from 2003 to 2011 at the National Cancer Center Hospital East, Japan. We re-evaluated preoperative thin-sliced computed tomography (TSCT) to determine solid size and pathological invasive size using the 3rd edition of the WHO classification and reclassified them according to the new TNM classification...

Langerhans cells are antigen presenting dendritic cells and tumours arising from these are rare. The tumours arising from these dendritic cells are divided into two categories according to a WHO classification: Langerhans cell histiocytosis and Langerhans cell sarcoma. It is the degree of atypia and clinical aggressiveness that distinguishes the two subtypes. Langerhans cell sarcoma (LCS) is a neoplastic proliferation of Langerhans cells which can occur in skin, bone marrow, lymph nodes, spleen, liver, and lung...

OBJECTIVES: Pleural invasion has been recognized as an important negative prognostic factor in non-small cell lung cancer (NSCLC), and therefore, accurate evaluation is required. However, when the visceral pleura adheres to the parietal pleura around a tumor and parietal pleural structures are destroyed and unrecognizable as a result of inflammation, it is often difficult to accurately evaluate pleural invasion, and classification of the T stage is unclear. To aid in categorization, we defined this status as pl1-3 and investigated the prognostic impact of the pl1-3 status on NSCLC...

Chronic elevation of pulmonary microvascular pressure (Pmv) consistently leads to alveolocapillary barrier thickening and reduction in the filtration coefficient. In animal models of chronic heart failure (CHF) the lung remains dry despite hydrostatic forces. As fluid flux is bi-directional, it has been postulated that an increase in alveolar fluid clearance may facilitate the dry lung when Pmv is chronically elevated. In this study we aimed to examine alveolar fluid clearance in ambulatory patients with CHF secondary to left ventricular (LV) systolic dysfunction compared against non-CHF controls...

Certain aspects of diagnosis, prognosis, and treatment of cancer patients are still important challenges to be addressed. Therefore, we propose a pipeline to uncover patterns of alternative polyadenylation (APA), a hidden complexity in cancer transcriptomes, to further accelerate efforts to discover novel cancer genes and pathways. Here, we analyzed expression data for 1045 cancer patients and found a significant shift in usage of poly(A) signals in common tumor types (breast, colon, lung, prostate, gastric, and ovarian) compared to normal tissues...
