The diagnosis of interstitial lung disease (ILD) is challenging and relies on a multidisciplinary discussion involving clinical, radiological and sometimes histological features. Bronchoscopic lung cryobiopsies have emerged as a new minimally invasive method of lung sampling and an alternative to surgical lung biopsies. A good diagnostic performance and excellent safety profile make it an interesting and worthful procedure which could decrease the number of patients without proper diagnosis and treatment. There is a need for further studies to standardize the technique in expert centers and to establish its role in the diagnostic work-up of ILD...

BACKGROUND AND PURPOSE: Small cell lung cancer (SCLC) is an aggressive disease with median survival of < 2 years. Tumour biopsies for research are scarce, especially from extensive-stage patients, with repeat sampling at disease progression rarely performed. We overcame this limitation for relevant preclinical models by developing SCLC circulating tumour cell derived explants (CDX) which mimic the donor tumour pathology and chemotherapy response. To facilitate compound screening and identification of clinically relevant biomarkers, we developed short term ex vivo cultures of CDX tumour cells...

Introduction: Nocardia are Gram-positive partially acid-fast bacilli capable of inducing a wide range of infections in patients with immunodeficiency, AIDS, cancer, lupus erythematous and diabetes. Nocardia cyriacigeorgica was first isolated in 2001 from a patient with chronic bronchitis. Since then, there have been reports on the clinical significance of this organism in patients with bronchitis, brain abscess and lung diseases. We, herein, report a case of brain abscess in an elderly diabetic patient from Iran...

Lung cancer is by far the leading cause of cancer death worldwide, with non-small cell lung cancer (NSCLC) accounting for the majority of cases. Recent advances in the understanding of the biology of tumors and in highly sensitive detection technologies for molecular analysis offer targeted therapies, such as epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors. However, our understanding of an individual patient's lung cancer is often limited by tumor accessibility because of the high risk and invasive nature of current tissue biopsy procedures...

BACKGROUND: Uniportal video-assisted thoracic surgery (VATS) is gaining popularity among thoracic surgeons, but the limited space in the thorax of children makes uniportal VATS difficult to perform. The purpose of this study was to evaluate procedural and outcome differences between a modified uniportal VATS (MU-VATS) and three-port VATS (TP-VATS) for peripheral lung nodule biopsy in pediatric cancer patients. MATERIALS AND METHODS: This is an Institutional Review Board-approved retrospective analysis of all consecutive MU-VATS and TP-VATS peripheral lung nodule biopsies performed at a single institution between June 2014 and December 2016...

Pulmonary pleomorphic carcinoma is defined as a nonsmall cell lung carcinoma (NSCLC) that contains at least 10% sarcomatoid components. We report a case of pulmonary pleomorphic carcinoma of which only the sarcomatoid component metastasized to the small bowel and adenocarcinoma was identified on percutaneous transthoracic needle biopsy (PTNB). We suggest that if an NSCLC is diagnosed by PTNB and a sarcoma is found at another site, or vice versa, pulmonary pleomorphic carcinoma with a single metastasis should be considered as a differential diagnosis to establish the best effective treatment plan...

An 83-year-old male who was a former smoker had pain on the left forearm accompanied with progressive swallowing in the last four to five months. Imaging studies revealed a cystic necrotic mass on the flexor digitorum superficialis muscle (biopsy: striated muscle tissue infiltrated by an adenocarcinoma). A whole-body computerized tomography (CT) scan demonstrates the presence of two lung masses that were suspicious of malignancy. Diagnosed as having stage IV lung adenocarcinoma (cT4NxM1b, IASLC TNM 8th [3]), he received chemotherapy with a carboplatin/pemetrexed-based regimen and local palliative radiation for the control of arm pain...

Patient navigation has been proposed to combat cancer disparities in vulnerable populations. Vulnerable populations often have poorer cancer outcomes and lower levels of screening, adherence, and treatment. Navigation has been studied in various cancers, but few studies have assessed navigation in lung cancer. Additionally, there is a lack of consistency in metrics to assess the quality of navigation programs. The authors conducted a systematic review of published cancer screening studies to identify quality metrics used in navigation programs, as well as to recommend standardized metrics to define excellence in lung cancer navigation...

Invasive aspergillosis (IA) is a deep tissue infection with a high mortality occurring mostly in immunocompromised patients. To investigate the pathology of patients with IA it may be important to determine the genotype of the invasive isolate of Aspergillus , however available tissues for study are often formalin fixed paraffin embedded (FFPE). Although DNA has been successfully isolated from such tissues for species identification, genotyping of Aspergillus species on such tissues has not yet been performed...

PD-L1 immunohistochemistry correlates only moderately with patient survival and response to PD-(L)1 treatment. Heterogeneity of tumor PD-L1 expression might limit the predictive value of small biopsies. Here we show that tumor PD-L1 and PD-1 expression can be quantified non-invasively using PET-CT in patients with non-small-cell lung cancer. Whole body PD-(L)1 PET-CT reveals significant tumor tracer uptake heterogeneity both between patients, as well as within patients between different tumor lesions.

Defined by the accumulation of red blood cells into the alveolar space, diffuse alveolar hemorrhage (DAH) is a severe and potentially fatal medical condition requiring careful attention. In contrast to simple extravasation of erythrocytes facilitated by impaired hemostasis or hemodynamic causes, DAH in vasculitis is due to capillaritis, that is, inflammation of capillaries. Dyspnea, hemoptysis, chest infiltrates, and abrupt fall of blood hemoglobin level represent the cardinal features of DAH; yet, hemoptysis is lacking in one-third of cases...

Purpose: Classic angiomyolipoma (AML) is common benign kidney tumor. However, some studies have claimed that epithelioid angiomyolipoma (EAML) has malignant potential. We compared the patient characteristics and prognosis of EAML and classic AML to demonstrate predicting factors and poorer prognosis of EAML. Materials and Methods: The medical records of 231 patients who were diagnosed with EAML (n=27, 11.7%) or classic AML (n=204, 88.3%), were reviewed. All patients underwent computed tomography (CT) scans before operation or needle biopsy...
