Distinguishing adrenal incidentalomas (5% of all abdominal CT scans) from metastasis is a frequent diagnostic challenge in primary malignancies with a propensity for adrenal spread, such as lung cancer. Adrenal myelolipoma and adenoma can be definitively characterized as benign by demonstrating gross and microscopic fat, respectively, on CT and MRI and an absence of abnormal uptake on PET. Unfortunately, adrenal sampling is frequently necessary in indeterminate cases for adequate staging of extra-adrenal primary malignancy...

To investigate the prognostic impact of MET copy number ( MET -CN) in patients with non-small cell lung cancer (NSCLC), we retrospectively reviewed clinical and pathologic data of NSCLC patients whose tumors were assessed for MET -CN using fluorescence in situ hybridization (FISH). We correlated MET -CN status with patient overall survival (OS) and optimized MET -FISH reporting criteria. The study group included 384 patients with NSCLC of which 88% were adenocarcinoma and 55.7% of patients had distant metastases...

Lung cancer is the most common malignant tumor with increasing angiopoietin-2 (Ang-2) and a high rate of metastasis. However, the mechanism of Ang-2 enhancing tumor proliferation and facilitating metastasis remains to be clarified. In this study, Ang-2 expression and its gene transcription on effects of biological behaviors and epithelial-mesenchymal transition (EMT) were investigated in lung cancers. Total incidence of Ang-2 expression in the cancerous tissues was up to 91.8 % (112 of 122) with significantly higher (χ2 =103...

Non-small cell lung cancer (NSCLC), including adenocarcinoma and squamous cell carcinoma, is the leading cause of death from lung malignancies and has a poor prognosis due to metastasis. Suppressor of cytokine signalling-2 (SOCS2), a feedback inhibitor of cytokine signalling, has been shown to be involved in growth control. Here, we show that SOCS2 were significantly downregulated in tumour foci in NSCLC patients. The expression levels of SOCS2 significantly correlated with clinical stage, lymph node metastasis, histological subtype and survival time...

PURPOSE: To determine, in a retrospective analysis of a large cohort of stage III non-small cell lung cancer patients treated with curative intent at our institution, whether having a pathologic complete response (pCR) influenced overall survival (OS) or freedom from recurrence (FFR) in patients who underwent definitive (≥60 Gy) neoadjuvant doses of chemoradiation (CRT). METHODS AND MATERIALS: At our institution, 355 patients with locally advanced non-small cell lung cancer were treated with curative intent with definitive CRT (January 2000-December 2013), of whom 111 underwent mediastinal reassessment for possible surgical resection...

PURPOSE: Prophylactic cranial irradiation (PCI) in patients with limited-stage small-cell lung cancer (LS-SCLC) is considered the standard of care. Meta-analysis of 7 clinical trials indicates a survival benefit to PCI, but all of these trials were conducted in the pre-magnetic resonance imaging (MRI) era. Therefore, routine brain imaging with MRI before PCI-as recommended by National Comprehensive Cancer Network guidelines-is not directly supported by the evidence. Current US practice patterns for patients with LS-SCLC are unknown...

Introduction: American Indian/Alaska Native (AI/AN) patients with cancer disproportionally present with more advanced stages of disease and have the worst cancer-specific survival rates of any racial/ethnic group in the United States. The presence of disparities in radiation therapy (RT) access for AI/AN patients has rarely been examined. Methods and materials: National Cancer Institute (NCI) initiatives toward addressing AI/AN disparities were examined. Additionally, an extensive PubMed literature search for studies investigating RT access disparities in AI/AN patients was performed...

The addition of bevacizumab to chemotherapy has demonstrated efficacy as a first-line treatment for non-small cell lung cancer (NSCLC). Whether this combination is effective as a salvage treatment for patients with NSCLC remains unclear. The present retrospective study was designed to compare the efficacy and safety of chemotherapy plus bevacizumab with chemotherapy alone as a third-line, or continuing, treatment for patients with NSCLC. Between January 2011 and June 2016, a total of 38 patients with stage IV NSCLC who had received chemotherapy plus bevacizumab subsequent to failure of ≥2 prior regimens were matched with 38 patients who had received chemotherapy alone using propensity score matching from a dataset of 165 patients...

Zinc finger protein 668 (ZNF668) is a recently discovered protein and its expression levels, as well as its involvement in the invasion and metastasis of non-small cell lung cancer (NSCLC), are largely unknown. In the present study, immunohistochemical analysis demonstrated that ZNF668 protein expression was decreased in lung tumors (51/167, 30.5%) compared with adjacent normal lung tissues (43/62, 69.4%; P<0.001). Subsequent statistical analysis revealed that ZNF668 expression was negatively associated with increased tumor-node-metastasis stage (P=0...

Accurate staging for non-small cell lung cancer (NSCLC) is essential to guide therapy. While computed tomography (CT) and positron emission tomography (PET) scan can indicate whether mediastinal lymphadenopathy is present, histologic confirmation is required to complete the staging evaluation. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive technique associated with similar diagnostic yield and improved postoperative pain and complication rates compared to mediastinoscopy...

Nowadays the treatment of patients with non-small cell lung cancer (NSCLC) that invades the chest wall is still questioned. The classic approach is a lobectomy that requires chest wall resection through thoracotomy, but thanks to the progress in the field of thoracoscopic surgery, this procedure can be performed by video-assisted thoracoscopic surgery (VATS). Major advances have been made in recent years both in the surgical technique associated with thoracoscopy and in the instrumentation available today. This has allowed the use of thoracoscopic technique even in advanced disease...

Lung cancer screening is a relatively new screening option. Inequalities related to screening behavior have been documented in other types of cancer screening. Because stage at presentation drives mortality in lung cancer, it is critical to understand factors that influence screening behavior in lung cancer screening in order to intervene. However, we must first understand where disparities exist in lung cancer screening participation in order to effectively guide intervention efforts. Therefore, the purpose of this study was to determine the association of sociodemographic (including key disparity-related variables) and knowledge with lung cancer screening behavior...
