OBJECTIVES: The objectives of this study were to evalute the metabolic characteristics of common malignant space-occupying lesions (SOL) of the brain and to determine the utility of fluorine-18-fluorodeoxyglucose (F-FDG) PET/CT in differentiating between the common types of malignant brain SOL. PATIENTS AND METHODS: All patients with brain SOL who were referred for an F-FDG PET/CT scan by a multidisciplinary team were included in this retrospective study. The metabolic characteristics of the brain lesions in the form of maximum standardized uptake value (SUVmax) along with tumor-to-background activity ratios were determined and differences were compared using nonparametric statistical tests...

PURPOSE: 4D cone-beam CT (CBCT) has potential applications in soft tissue alignment and tumor motion verification at the time of radiation treatment. However, prominent streak artifacts with conventional image reconstructions have limited its clinical use and alternative reconstructions are generally too computationally expensive for the time available. We propose an iterative volume of interest based (I4D VOI) reconstruction technique, where 4D reconstruction is only performed within a VOI, to limit streak artifacts with limited added computation time...

Renal function impairment in lung cancer patients with bone metastases was investigated, as this can limit the application of bisphosphonates representing the gold standard in the management of such cases. Clinicopathological data of 570 lung cancer patients were retrospectively analysed for changes in renal function parameters. Co-morbidities included hypertension (50%), COPD (33%) and diabetes mellitus (15%). Statistical analysis was performed with Fisher's exact tests and a Cox proportional hazards model...

The paper is motivated by the problem of comparing the accuracy of two molecular tests in detecting genetic mutations in tumor samples when there is no gold standard test. Commonly used sequencing methods require a large number of tumor cells in the tumor sample and the proportion of tumor cells with mutation positivity to be above a threshold level whereas new tests aim to reduce the requirement for number of tumor cells and the threshold level. A new latent class model is proposed to compare these two tests in which a random variable is used to represent the unobserved proportion of mutation positivity so that these two tests are conditionally dependent; furthermore, an independent random variable is included to address measurement error associated with the reading from each test, while existing latent class models often assume conditional independence and do not allow measurement error...

Lung cancer remains the leading cause of death in cancer patients. The gold standard for the treatment of early-stage non-small-cell lung cancer is lobectomy with mediastinal lymph-node dissection or systematic lymph-node sampling. The evidence behind this recommendation is based on the sole randomized controlled trial conducted to date, done by the Lung Cancer Study Group and published in 1995, which found a superiority for lobectomy over sublobar resection with regard to local recurrence rate and improved survival...

Lung cancer is the leading cancer worldwide among men and women with morbidity reaching 1.6 million. Human Papillomavirus is the causal factor of cervical cancer while its association with others is still under investigation. The purpose of our study is to examine the presence of HPV DNA as well as high-risk E6/E7 mRNA in patients with lung cancer. Lung tissues were collected during bronchoscopy and tested for HPV DNA and E6/E7 mRNA. 67 lung tissue samples were analysed. The age range was 49-85 years old (y...

The brain is the most common site of distant metastasis from lung cancer. Thus, MRI of the brain at initial staging is routinely performed, but if this examination is negative a follow-up examination is often not performed. This study evaluates the incidence of asymptomatic brain metastases in non-small cell lung cancer patients detected on follow-up (18)F-FDG PET/CT scans. Methods: In this Institutional Review Board-approved retrospective review, all vertex to thigh (18)F-FDG PET/CT scans in patients with all subtypes of lung cancer from August 2014 to August 2016 were reviewed...

This review aims to appraise the role of physiotherapy care in patients submitted to pulmonary surgery, in preoperative, perioperative, and postoperative phases. Pulmonary surgery is the gold standard treatment for patients with lung cancer if it is completely resectable. However, the major impairments and complications induced by surgery are well known. Physiotherapy has been regularly used both in the preparation of the surgical candidates; in their functional recovery in the immediate postoperative period, and in the medium/long term but there is a lack of concise evidence-based recommendations...

BACKGROUND: Improvements in systemic therapy for metastatic colorectal cancer (CRC) have markedly extended survival, rendering local control of metastases to critical organs of increasing importance, especially in the oligometastatic setting where the disease may not yet have acquired the ability to widely disseminate. While surgical resection remains the gold standard for oligometastases in many organs, stereotactic body radiation therapy (SBRT) presents a non-invasive alternative for achieving local control...

The gold standard test for detection of epidermal growth factor receptor (EGFR) mutation is to genotype somatic DNA extracted from a tissue biopsy or cytology specimen. Yet, in at least 20% of patients this is not possible for various reasons including insufficient availability of neoplastic tissue, lack of fitness of the available tissue for a biopsy or that a biopsy is not technically feasible. Consequently, there has been intense investigation of circulating tumour DNA (ctDNA), released into the plasma fraction of blood from cancer cells during apoptosis/necrosis, as a minimally invasive 'liquid biopsy' and surrogate for cancer tissue...

BACKGROUND: Surgical resection with curative-intent remains the gold standard for clinically operable early-stage non-small cell lung cancer (NSCLC). This goal can be accomplished using a minimally invasive option, e.g., video assisted thoracic surgery (VATS) or standard thoracotomy. Surgical techniques continue to evolve and few studies have compared the QOL of patients managed with these procedures using current approaches. The primary goal of this study was to investigate differences between patients managed surgically via VATS compared to thoracotomy with respect to ratings of chronic pain, anxiety/depression and quality of life (QOL)...

Objective: To study the etiological, clinical, radiological, diagnostic, therapeutic, and prognostic manifestations of exogenous lipoid pneumonia (ELP), and therefore to improve the diagnosis and treatment of this disease. Methods: The clinical data of 12 cases of ELP confirmed by pathology were retrospectively analyzed. Results: The patients consisted of 9 males and 3 females, with an average age of 73.8 years (range, 44 to 100 years). The underlying diseases were variable, including diseases affecting the general condition (multiple organ failure, chronic heart and renal insufficiency, pemphigoid, etc) and conditions with increased risk of aspiration (sequelae of cerebrovascular disease, Alzheimer's disease, advanced stage of nasopharyngeal carcinoma, paralytic ileus, etc)...

The aim of this work is to assess the performance of 2D time-integrated (2D-TI), 2D time-resolved (2D-TR) and 3D time-integrated (3D-TI) portal dosimetry in detecting dose discrepancies between the planned and (simulated) delivered dose caused by simulated changes in the anatomy of lung cancer patients. For six lung cancer patients, tumor shift, tumor regression and pleural effusion are simulated by modifying their CT images. Based on the modified CT images, time-integrated (TI) and time-resolved (TR) portal dose images (PDIs) are simulated and 3D-TI doses are calculated...

OBJECTIVE: Although driver mutation status is crucial to targeted therapy decision-making in non-small cell lung cancer (NSCLC), due to unavailable or inadequate biopsies, there are still many patients with unknown mutation status. A promising way to solve this problem is liquid biopsy, such as cell-free DNA (cfDNA) in peripheral blood. Additionally, due to the little amount of cfDNA, detecting methods with high sensitivity, specificity and economy are required in clinical practice. Here, we explored the feasibility of Competitive Allele-Specific TaqMan® PCR (CastPCR) detecting driver mutations in cfDNA from plasma in lung adenocarcinoma patients...

Cigarette smoking is the most frequently encountered risk factor for chronic obstructive pulmonary disease and lung cancer. The latest American Thoracic Society÷European Respiratory Society classification of idiopathic interstitial pneumonia includes two entities related to smoking habits: respiratory bronchiolitis-associated interstitial lung disease and desquamative interstitial pneumonia. The new approach to diagnosis is to combine pathological pattern with clinical and radiological data. Lung biopsy is no longer considered the "gold standard" for diagnosis, but as a part of the diagnosis, which shall be set only after the pulmonologist, radiologist and pathologist reviewed all clinical, imaging and pathological aspects...

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive method for diagnosing and staging of lung cancer. EBUS-TBNA obtained small specimens. Rapid on-site examination (ROSE) is a rapid, real-time examination method. The aim of our study is to evaluate the impact of ROSE on adequate specimen sampling, rapid results and high diagnostic rate. We present the experience of the Department of Bronchology, "Leon Daniello" Clinic of Pulmonology, Cluj-Napoca, Romania, with EBUS-TBNA as a tool for diagnostic of adenopathies of unknown etiology...

A challenge in precision medicine requires identification of actionable driver mutations. Critical to such effort is the deployment of sensitive and well-validated assays for mutation detection. Although identification of such alterations within the tumor tissue remains the gold standard, many advanced non-small cell lung cancer cases have only limited tissue samples, derived from small biopsies or fine-needle aspirates, available for testing. More recently, noninvasive methods using either circulating tumor cells or tumor DNA (ctDNA) have become an alternative method for identifying molecular biomarkers and screening patients eligible for targeted therapies...
