Activation of the epithelial-mesenchymal transition process (EMT) by which alveolar cells in human lung tissue undergo differentiation giving rise to a mesenchymal phenotype (fibroblast/miofibroblasts) has been well recognized as a key element in the origin of idiopathic pulmonary fibrosis (IPF). Here we analyzed expression of AQP1 in lung biopsies of patients diagnosed with IPF, and compared it to biopsies derived from patients with diverse lung pneumonies, such as hypersensitivity pneumonitis, sarcoidosis or normal lungs...

An 84-year-old man was referred to our hospital with swollen right cervical lymph nodes. Computed tomography showed right supraclavicular and mediastinal lymph node enlargement, and fluorodeoxyglucose positronemissiontomography showed multiple areas of abnormally increased radioactivity inthe right supraclavicular and mediastinal lymph nodes, right ninth rib, and left fifth and seventh ribs. Biopsy of the right supraclavicular lymph node revealed metastatic adenocarcinoma with partial immunohistochemical staining for prostate specific antigen (PSA)...

PURPOSE: Hepatocellular carcinoma (HCC) results from chronic inflammation/cirrhosis. Unfortunately, despite use of radiological/serological screening techniques, HCC ranks as a leading cause of cancer deaths. Our group has used alterations in high order chromatin as a marker for field carcinogenesis and hence risk for a variety of cancers (including colon, lung, prostate, ovarian, esophageal). In this study we wanted to address whether these chromatin alterations occur in HCC and if it could be used for risk stratification...

BACKGROUND: Flexible bronchoscopy with endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration (TBNA) is increasingly being used to obtain pathology specimens for diagnosis of sarcoidosis. There is wide variation in reported diagnostic yield in literature. New TBNA needles are available in the market but data are lacking about their diagnostic yield especially for sarcoidosis. This study reports the diagnostic yield of bronchoscopy with EBUS-TBNA using ViziShot FLEX 19-G needle in a series of patients with suspected sarcoidosis...

RATIONALE: Metastases of breast carcinoma to the main bronchus and choroid are rare, but have been reported in relevant literature. Late distant recurrence of breast carcinoma after more than 20 years is extremely rare. Herein, we report a 57-year-old woman with late distant recurrence and metastasis to the main bronchus and choroid almost 28 years after surgery. PATIENT CONCERNS: At the age of 29, the patient underwent chemotherapy and endocrine treatment after a right side mastectomy to remove breast carcinoma...

Knowledge about cancer biology is extending and has meaningful repercussions on patients' care. Therefore, there is a growing need to assess tumor biology not only at diagnosis, but also throughout the course of management. Tumor tissue biopsies are particularly useful, but are not convenient for repetitive analyses because of the need for invasive procedures. Advances in biotechnology allow currently getting more and more information from liquid biopsies, based on small amounts of tumor material released for instance into the peripheral blood...

BACKGROUND: Non-small cell lung cancer (NSCLC) patients with epidermal growth factor receptor (EGFR) mutations or anaplastic lymphoma kinase (ALK) fusions show dramatic responses to specific tyrosine kinase inhibitors (TKIs); however, after 10-12 months, secondary mutations arise that confer resistance. We generated a murine xenograft model using patient-derived NSCLC cells isolated from the pleural fluid of two patients with NSCLC to investigate the mechanisms of resistance against the ALK- and EGFR-targeted TKIs crizotinib and osimertinib, respectively...

BACKGROUND: In cases of EGFR-tyrosine kinase inhibitor (TKI) failure, re-biopsy may be useful to understand resistance mechanisms and guide further treatment decisions. However, performing re-biopsy is challenging because of several hurdles. We assessed the feasibility of re-biopsy in advanced non-small cell lung cancer (NSCLC) patients in real-world clinical practice. METHODS: We retrospectively reviewed the clinical and pathologic data of advanced NSCLC patients who experienced disease progression after previous treatment with EGFR-TKIs at a single tertiary hospital in Korea between January 2014 and December 2016...

INTRODUCTION: Idiopathic pulmonary fibrosis (IPF) is considered a disease of older patients, being rare in patients ≤ 50 years. Still, IPF can occur in younger patients, but this particular patient group is not well characterised so far. The aim of this study was to compare the diagnostic certainty, clinical features, comorbidities and survival in young versus older IPF patients. METHODS: We reviewed our medical records from February 2011 until February 2015, to identify IPF patients, who were then classified as young (≤ 50 years) or older IPF (> 50 years)...

Presacral myelolipomas are rare, benign, asymptomatic tumors composed of mature adipose tissue and hematopoietic elements. Presacral myelolipomas can occur in patients with a medical history of malignancy, steroid use, and/or endocrine disorders including diabetes mellitus. A 65-year-old man with no specific medical history experienced temporal abdominal pain without bowel symptoms that lasted a few hours. By the time he visited a hospital, the pain had diminished. Computed tomography failed to detect any abnormality in the abdominal or pelvic organs that would have caused the abdominal pain but revealed a lesion 4 cm in diameter in the frontal sacrum...

Mutations in POMT2 are most commonly associated with Walker-Warburg syndrome and Muscle-Eye-Brain disease, but can also cause limb girdle muscular dystrophy (LGMD2N). We report a case of LGMD due to a novel mutation in POMT2 unmasked by uniparental isodisomy. The patient experienced proximal muscle weakness from three years of age with minimal progression. She developed progressive contractures and underwent unilateral Achilles tenotomy. By age 11, she had borderline low left ventricular ejection fraction and mild restrictive lung disease...

Circulating tumor cells (CTCs) have become an important biomarker for liquid biopsy to monitor tumor progression and indicate response to therapies. Many epithelial cellular adhesion molecule (EpCAM) dependent CTC isolation methods have been developed, which have a limitation for low EpCAM expressed tumor cells. In an effort to overcome these drawbacks, we developed combined immunomagnetic beads (EpCAM, Mucin1 and epidermal growth factor receptor) to sensitively isolate CTCs for immunofluorescence analysis and genetic characterization...

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...
