Lung cancer, compared with other solid tumors, is associated with high mortality rates from febrile neutropenia. The risk factors associated with in-hospital mortality were identified and compared for patients with lung cancer and patients with other solid tumors. Hospitalization data from the University Health Consortium database inclusive of 2004 to 2012 were analyzed. The study population included all adult patients with solid tumors who developed neutropenia. Cancer type, the presence of neutropenia, and further subgroups were determined using International Classification of Diseases, 9th revision, Clinical Modification codes...

Objectives: According to the IASLC/ATS/ERS 2011 classification, there are two new conceptions of lung adenocarcinoma, adenocarcinoma in situ (AIS), minimally invasive adenocarcinoma (MIA), which are very early stages of lung adenocarcinoma. This study aimed to analyze clinical features of AIS and MIA and determine the expression profile of PD-L1 in AIS and MIA. Results: In all 274 patients, 77 were diagnosed as AIS and 197 as MIA. We accidentally found 4 patients with recurrence, which were all MIA...

Objectives: Posttransplant lymphoproliferative disorders (PTLDs) are a heterogeneous group of hematolymphoid proliferations arising in the context of chronic immunosuppression. The common and indolent B-cell lymphomas, including extranodal marginal zone lymphomas (ENMZLs) of mucosa-associated lymphoid tissue (MALT), are excluded from the category of PTLD in the current World Health Organization classification. Methods: We report a case of Epstein-Barr virus (EBV)-positive bronchial-associated lymphoid tissue (BALT) lymphoma involving the lungs of a transplant patient...

The purpose of this study is to develop a computed tomography (CT) biomarker of emphysema that is robust across reconstruction settings, and evaluate its ability to predict mortality in patients at high risk for lung cancer. Data included baseline CT scans acquired between August 2002 and April 2004 from 1737 deceased subjects and 5740 surviving controls taken from the National Lung Screening Trial. Emphysema scores were computed in the original scans (origES) and after applying resampling, normalization and bullae analysis (normES)...

Studies suggest that long-term chronic exposure to fine particulate matter air pollution can increase lung cancer mortality. We analyzed the association between long term PM2.5 and ozone exposure and mortality due to lung cancer, ischemic heart disease, and chronic obstructive pulmonary disease, accounting for geographic location, socioeconomic status, and residential mobility. Subjects in the 1991 Canadian Census Health and Environment Cohort (CanCHEC) were followed for 20years, and assigned to regions across Canada based on spatial synoptic classification weather types...

The group of non-small cell lung carcinomas includes tumors that are variable at the clinical, histopathological and molecular levels. Advances in the understanding of molecular pathology of lung adenocarcinomas in particular led to changes in their histopathological classification and treatment. Patients diagnosed with lung adenocarcinoma harboring specific mutations benefit from the administration of specific targeted therapy. Analysis of EGFR gene mutations and ALK rearrangement in lung adenocarcinomas are already routinely performed and are closely related to the indication for the administration of tyrosinkinase inhibitors...

An atypical type A thymoma is a newly added entity to the last World Health Organization (WHO) histological classification [2015] of uncertain prognosis. The conventional type A and AB thymomas are usually locally aggressive neoplasms that rarely metastasize with distant metastases to the central nervous system (CNS) occurring extremely exceptionally. We present a history of a woman with a mediastinal tumor originally considered to be a Masaoka-Koga stage II "mixed thymoma with well-differentiated thymic carcinoma component" according to the historic Müller-Hermelink nomenclature...

A 35-year-old woman had undergone extensive thymothymectomy for type A thymoma several years ago. However, two small lung nodules were found 4 and 5 years after surgery. After a partial lung resection to remove these nodules, pathology revealed that they were metastases of the type A thymoma. A pathological re-evaluation confirmed that the primary tumor had in fact been an atypical type A thymoma variant, a subset added to the WHO classification in 2015. Pathology should be re-evaluated in all patients diagnosed with type A thymoma before 2015 since they may have the more aggressive atypical type A thymoma variant...

Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is hyperplasia of noninvasive neuroendocrine cells originating from Kultchitsky cells. This is a rare pathological condition, suspected to be a precursor lesion of carcinoid, together with tumorlet. In the WHO histological classification (4th edition) revised in 2015, DIPNECH was added to the category that includes neuroendocrine tumors. Our patient was a 77-year-old woman who initially visited another doctor because of coughing. Chest CT revealed a mass occluding the right intermediate bronchial trunk, and bronchial carcinoid was suspected from biopsy findings, leading to referral of this patient to our department...

BACKGROUND: The improvement in sickle cell anemia (SCA) care resulted in the emergence of a large population of adults living with this disease. The mechanisms of lung injury in this new population are largely unknown. The forced oscillation technique (FOT) represents the current state-of-the-art in the assessment of lung function. The present work uses the FOT to improve our knowledge about the respiratory abnormalities in SCA, evaluates the associations of FOT with the functional exercise capacity and investigates the early detection of respiratory abnormalities...

On May 23, 2017, the US Food and Drug Administration (FDA) approved a treatment for cancer patients with positive microsatellite instability-high (MSI-H) markers or mismatch repair deficient (dMMR) markers. This approach is the first approved tumor treatment using a common biomarker rather than specified tumor locations in the body. FDA previously approved Keytruda for treatment of several types of malignancies, such as metastatic melanoma, metastatic non-small-cell lung cancer, recurrent or metastatic head and neck cancer, refractory Hodgkin lymphoma, and urothelial carcinoma, all of which carry positive programmed death-1/programmed death-ligand 1 biomarkers...

Radiomics, which involves the extraction of large numbers of quantitative features from medical images, has attracted attention in cancer research. In radiomics analysis, tumor segmentation is a crucial step. In this study, we evaluated the potential application of radiomics for predicting the histology of early stage non-small cell lung cancer (NSCLC) by analyzing interobserver variability in tumor delineation. Forty patient datasets were included in this study, 21 involving adenocarcinomas and 19 involving squamous cell carcinomas...

BACKGROUND AND OBJECTIVE: The diagnostic classification of 'possible idiopathic pulmonary fibrosis (posIPF)' is characterized by a radiological pattern of inconsistent usual interstitial pneumonia (UIP) on high-resolution computed tomography (HRCT) scan and a UIP pattern in surgical lung biopsy (SLB). The evidence base to guide treatment for patients with posIPF is lacking; the clinician must choose between observation, treatment with immunomodulatory agents or anti-fibrotic agents. METHODS: To evaluate outcomes of immunomodulatory treatment, a multicentre cohort of 59 posIPF patients treated with prednisone was analysed retrospectively...

The abnormal expression of the chicken ovalbumin upstream promoter transcription factor 2 (COUP‑TFII) is associated with numerous forms of cancer, including gastric, prostate, colon and lung cancer. However, previous studies investigating the association between COUP‑TFII expression and the occurrence, recurrence, invasion and metastasis of gastric cancer are limited in number. In the present study, it was revealed that the expression of COUP‑TFII is significantly reduced in gastric carcinoma tissues compared with normal gastric mucosa cells (GES‑1)...

Lung cancer is the second most common cancer and is the leading cause of cancer-related death worldwide. For decades, increasing evidence revealed that microRNAs may contribute to non‑small cell lung cancer (NSCLC) carcinogenesis and progression and could provide novel therapeutic targets for treatments of patients with NSCLC. Accumulated studies indicate that microRNA (miR)‑363‑3p serves important roles in tumorigenesis and tumor development; however, the role of miR‑363‑3p in NSCLC is still unclear...
