OBJECTIVES: The goal of this study was to investigate the role of the ground-glass opacity (GGO) ratio in lung adenocarcinoma in predicting surgical outcomes. METHODS: Patients who underwent surgical resection for pulmonary adenocarcinoma between January 2004 and December 2013 were reviewed. The clinical data, imaging characteristics of nodules, surgical approaches and outcomes were analysed with a mean follow-up of 87 months. RESULTS: Of 789 enrolled patients, 267 cases were categorized as having a GGO ratio ≥0...

OBJECTIVE: Pulmonary mucormycosis is an aggressive opportunistic fungal infection. We set out to evaluate the CT and MRI features of pulmonary mucormycosis. MATERIALS AND METHODS: Through a search of the electronic medical record from 2007 to 2017, we identified 30 patients with definite or probable mucormycosis. Two radiologists reviewed the initial chest CT examinations for the presence of features including the "reverse halo" sign, large ground-glass halo, and peripheral lesion distribution...

BACKGROUND: Women treated for breast cancer are at increased risk of developing pulmonary nodules which could represent new primary lung carcinomas or metastatic breast carcinoma. The FNA biopsy is frequently the first diagnostic choice in determining the primary site of the tumor. Estrogen receptor (ER) positivity in diagnostic tissue is generally used to favor breast over lung primary. However, the recent studies have shown a wide range of ER antibody cross reactivity with lung adenocarcinoma...

Development of molecular markers that help to identify high-risk individuals or diagnose indeterminate pulmonary nodules could have a major impact on lung cancer clinical management. In this study, we evaluated the diagnostic potential of a newly-developed ELISA that specifically detects complement C4d. We measured this marker in five independent cohorts of plasma and bronchoalveolar lavage samples from lung cancer patients and controls. In case-control studies, the area under the ROC curve for the diagnosis of lung cancer was 0...

Lung cancer remains the leading cause of cancer-related death due to its advanced stage at diagnosis. Early detection of lung cancer can be improved by better defining who should be screened radiographically, and determining which imaging-detected pulmonary nodules are malignant. Gene expression biomarkers measured in normal-appearing airway epithelium provide an opportunity to use lung cancer associated molecular changes in this tissue for early detection of lung cancer. Molecular changes in the airway may result from an etiologic field of injury and/or field cancerization...

INTRODUCTION: Syphilis is a sexually transmitted disease that can affect numerous organs in its secondary or tertiary stages. We describe a case of secondary syphilis with pulmonary involvement and we present a literature review. PATIENTS AND METHODS: A 69-year-old male patient was admitted to hospital for dyspnoea and extended papular exanthema with palmoplantar involvement. The serological test for syphilis was positive. Ocular examination showed bilateral papillitis and retinal haemorrhage...

PURPOSE: To develop a radiomics prediction model to improve pulmonary nodule (PN) classification in low-dose CT. To compare the model with the American College of Radiology (ACR) Lung CT Screening Reporting and Data System (Lung-RADS) for early detection of lung cancer. METHODS: We examined a set of 72 PNs (31 benign and 41 malignant) from the Lung Image Database Consortium image collection (LIDC-IDRI). 103 CT radiomic features were extracted from each PN. Before the model building process, distinctive features were identified using a hierarchical clustering method...

BACKGROUND: Lung nodules that are small and deep within lung parenchyma, and have semisolid characteristics are often challenging to localize with video-assisted thoracoscopic surgery (VATS). We describe our cumulative experience using needle localization of small nodules before surgical resection. We report procedural tips, operative results, and lessons learned over time. METHODS: A retrospective review of all needle localization cases between July 1, 2006, and December 30, 2016, at a single institution was performed...

BACKGROUND: The pure ground-glass nodule is a common clinical concern. The purpose of this study was to develop a nomogram to predict the risk of invasive pulmonary adenocarcinoma in patients with pure ground-glass nodules 1 cm or less in diameter based on the computed tomography imaging features. METHODS: We reviewed a total of 250 patients who had undergone resection of pure ground-glass nodules 1 cm or less in diameter in our hospital, including the data of histopathologic examinations after surgical resection...

CONTEXT: Bronchopulmonary neuroendocrine tumours (bpNETs) and thymic carcinoid (ThC) are features of Multiple Endocrine Neoplasia Type 1 (MEN 1) and surveillance guidelines recommend periodic thoracic imaging. The optimal thoracic imaging modality and screening frequency remains uncertain as does the prognosis of small lung nodules when identified. OBJECTIVES: To evaluate fluorodeoxyglucose positron emission tomography/computed tomography ( 18 F-FDG PET/CT) for identification and prognostic assessment of thoracic lesions in MEN 1...

Lung cancer screening aims to detect small pulmonary nodules and decrease the mortality rate. However, studies from large-scale clinical trials of lung cancer screening showed false-positive rate is high and positive predictive value is low. To address these problems, it is highly needed to have a technical approach for accurate malignancy differentiation among these early-detected nodules. We studied the clinical feasibility of an additional protocol of localized thin-section CT for further assessment on these recalled patients from lung cancer screening tests...

Giant-cell carcinoma of the lung (GCCL) is a rare histological form of poorly differentiated non-small-cell lung cancer, which is classified as a subtype of pulmonary sarcomatoid carcinomas. In this case report, we describe the case of a 50-year-old Chinese male who presented with a pulmonary nodule in the right upper lobe of his lung. After thoracoscopic lobectomy, a histopathologic diagnosis of GCCL was made. He did well postoperatively, showing no local recurrence or distal disease in a 7-year follow-up period...

BACKGROUND: Evidence is increasing that microRNAs (miR) are particularly important in lung homeostasis and development and have been shown to be involved in many pulmonary diseases such as asthma, chronic obstructive pulmonary disease, sarcoidosis, lung cancer (LC) and other smoking-related diseases. OBJECTIVE: The objective of this study was to investigate the expression of miR-155 and miR-486-5p in tissues from LC patients and healthy endobronchial mucosa as prognostic biomarkers for diagnosing LC...

Tuberous Sclerosis Complex (TSC) is a multisystemic condition caused by mutations in TSC1 or TSC2, but a pathogenic variant is not identified in up to 10% of the patients. The aim of this study was to delineate the phenotype of pediatric and adult patients with a definite clinical diagnosis of TSC and no mutation identified in TSC1 or TSC2. We collected molecular and clinical data of 240 patients with TSC, assessing over 50 variables. We compared the phenotype of the homogeneous group of individuals with No Mutation Identified (NMI) with that of TSC patients with a TSC1 and TSC2 pathogenic variant...

PURPOSE: Incidental solitary pulmonary nodules (SPNs) have become an increasingly common CT finding worldwide. Although there are currently many imaging strategies for evaluating SPNs, the differential diagnosis and management of SPNs remains complex because of overlap between benign and malignant processes. Moreover, transbronchial or percutaneous CT-guided biopsies do not always allow definitive diagnoses. In such cases, video-assisted thoracic surgery (VATS) has become the preferred surgical procedure for diagnosis and, in selected cases, for treatment of indeterminate SPNs...

Pulmonary hypertension (PH) is a condition characterized by increased pressure in the pulmonary circulation. It may be idiopathic or arise in the setting of other clinical conditions. Patients with PH tend to present with nonspecific cardiovascular or respiratory symptoms. The clinical classification of PH was recently revised at the World Health Organization symposium in Nice, France, in 2013. That consensus statement provided an updated classification based on the shared hemodynamic characteristics and management of the different categories of PH...
