BACKGROUND: Guidelines recommend, and Medicare requires, shared decision-making between patients and clinicians before referring individuals at high risk of lung cancer for chest CT screening. However, little is known about the extent to which shared decision-making about lung cancer screening is achieved in real-world settings. OBJECTIVE: To characterize patient and clinician impressions of early experiences with communication and decision-making about lung cancer screening and perceived barriers to achieving shared decision-making...

Lung adenocarcinoma is frequently occurring type of lung cancer with high metastatic risk. We performed a DNA methylation profiling analysis to identify possible prognostic markers involved in lung adenocarcinoma. DNA methylation profiling data (GSE66386) were downloaded from the Gene Expression Omnibus (GEO) database. Differentially methylated genes were identified using a limma package. GO enrichment analysis was performed to identify vital functions related to differential gene methylation, and pathway analysis was performed to assess the associations between different proteins with regard to regulation of cell function and metabolism...

Annual chest computed tomography (CT) can decrease lung cancer mortality in high-risk individuals. Patient navigation improves cancer screening rates in underserved populations. Randomized controlled trial was conducted from February 2016 to January 2017 to evaluate the impact of a patient navigation program on lung cancer screening (LCS) among current smokers in five community health centers (CHCs) affiliated with an academic primary care network. We randomized 1200 smokers aged 55-77 years to intervention (n = 400) or usual care (n = 800)...

BACKGROUND: ROS1 immunohistochemistry (IHC) using D4D6 antibody is a useful tool for screening patients with non-small cell lung cancer (NSCLC) slated for targeted therapy. Many studies and our data have identified cases that express the ROS1 protein strongly but are negative for ROS1 by fluorescent in situ hybridization (FISH). The present study investigated the driver mutation and clinicopathologic characteristics of 26 discordant cases (ROS1 IHC-positive but FISH-negative) to find new clues for distinguishing real ROS1-rearranged cases...

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...

Synthetic lethality is a molecular targeted therapy for selective killing of cancer cells. We exploited a lethal interaction between Superoxide dismutase1 inhibition and Bloom syndrome gene product (BLM) defect for the treatment of colorectal cancer (CRC) cells (HCT 116) with lung cancer screen-1 (LCS-1) loaded customized nanocarrier. LCS-1 has poor aqueous solubility. To overcome its limitations, customized nanocarrier (NC), composed of magnetite core coated with three polymeric shells namely, aminocellulose, branched poly(amidoamine) and paraben-PEG, was developed for encapsulating LCS-1...

BACKGROUND: Rearrangements of the ROS1 oncogene are found in 1% to 2% of non-small cell lung cancers (NSCLC) and are regarded as mutually exclusive oncogenic driver mutations. Since the approval of targeted therapy for ROS1-positive NSCLC, ROS1 testing has become a part of the diagnostic routine. Fluorescence in situ hybridization (FISH), optionally selected for by immunohistochemistry on histological material, is a common practice for the detection of ROS1 rearrangements. However, NSCLC often is diagnosed by cytology alone, requiring predictive marker testing on cytological specimens...

Metaplastic breast carcinoma (MBC) is rare and has a poor prognosis. Here we describe genetic analysis of a 41-year-old female patient with MBC and neurofibromatosis type I (NF1). She initially presented with pT3N1a, grade 3 MBC, but lung metastases were discovered subsequently. To identify the molecular cause of her NF1, we screened for germline mutations disrupting NF1 or SPRED1, revealing a heterozygous germline single nucleotide variant (SNV) in exon 21 of NF1 at c.2709G>A, chr17: 29556342. By report, this variant disrupts pre-mRNA splicing of NF1 transcripts...

Candidate patients for cardiac surgery procedures with a history of malignancies and antitumour therapy or with an active cancer and on antineoplastic treatment are increasingly common in daily practice. Oncological therapy can lead to cardiovascular injury and, therefore, has the potential for impacting operative risks and surgical strategies. This means that a number of considerations are essential to take into account prior to cardiac surgery. These include the type of cancer, previous cardiotoxicity or concomitant antitumour therapy, reversibility or irreversibility of such complications, the interaction between cancer disease course and extracorporeal circulation, the need for associated surgery and the impact of cancer on early and long-term outcomes...

Previous studies have demonstrated the association between EGFR mutations and distant metastasis. However, the association for subsequent brain metastasis (BM) in stages I-III non-small cell lung cancer (NSCLC) patients remains inconclusive. We conducted a retrospective analysis to clarify the impact of EGFR mutations on the incidence of BM and associated survival in patients with stage I-III NSCLC. A total of 491 patients screened for EGFR mutations were retrospectively enrolled. Brain MRI or CT was used to detect the BM...

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...

In the era of lung cancer screening and early detection of lung lesions, pulmonary segmentectomy has gained wide acceptance between thoracic community reducing the need of lobectomy for diagnostic purpose and treatment in case of centrally located benign, multiple or undetermined lesions. In rigorously selected patients with stage I non-small cell lung cancer (NSCLC), segmentectomies seem to offer similar survival outcomes rather than lobectomies, but associated with a better conservation of lung function. However, segmentectomy is a more challenging procedure to be performed compared to lobectomy, especially by video-assisted thoracic surgery (VATS)...

K-RAS is mutated in approximately 30% of human cancers, resulting in increased RAS signaling and tumor growth. Thus, RAS is a highly validated therapeutic target, especially in tumors of the pancreas, lung and colon. Although directly targeting RAS has proven to be challenging, it may be possible to target other proteins involved in RAS signaling, such as the guanine nucleotide exchange factor Son of Sevenless (SOS). We have previously reported on the discovery of small molecules that bind to SOS1, activate SOS-mediated nucleotide exchange on RAS, and paradoxically inhibit ERK phosphorylation (Burns et al...
