Therapeutic options for treating Non-Small Cell Lung Cancer (NSCLC) have recently increased. Ramucirumab (Cyramza), an anti-angionenic agent was approved in 2014 for treatment of several malignancies, including second-line treatment of patients with NSCLC with disease progression on or after platinum-based chemotherapy. Areas covered: We performed a comprehensive search of the literature focused on clinical trials with use of ramucirumab, targeting its evolution in the treatment of NSCLC.

The diagnosis of malignant pleural mesothelioma (MPM) is challenging and requires immunohistochemistry or electron microscopy assays to specifically differentiate MPM from lung adenocarcinoma. An ultrastructural study of fresh tissue is considered to be the "gold standard." In most cases, the first diagnostic approach is performed on pleural effusion, and in some patients, this is the only available sample for diagnosis.

Glioblastoma is the most aggressive tumor in Central Nervous System in adults. Among its features, modulation of immune system stands out. Although immune system is capable of detecting and eliminating tumor cells mainly by cytotoxic T and NK cells, tumor microenvironment suppresses an effective response through recruitment of modulator cells such as regulatory T cells, monocyte-derived suppressor cells, M2 macrophages, and microglia as well as secretion of immunomodulators including IL-6, IL-10, CSF-1, TGF-β, and CCL2.

Background And Objective: There is no consensus about apparent diffusion coefficient (ADC) values in acute stroke regions that could be used by clinicians in a day-to-day clinical practice; regional measures using confidence intervals (CIs) and a graphic representation of means are scarce in the literature. Our aim in this study was to compare ADC values in infarct, penumbra, and normal brain regions in patients with acute ischemic stroke (AIS).

Methods: This is a retrospective study of 100 magnetic resonance imaging data sets from AIS patients.

Recently, several medical societies published joint statements about imaging recommendations for acute stroke and transient ischaemic attack patients. In following with these published guidelines, we considered it appropriate to present a brief, practical and updated review of the most relevant concepts on the MRI assessment of acute stroke. Basic principles of the clinical interpretation of diffusion, perfusion, and MRI angiography (as part of a global MRI protocol) are discussed with accompanying images for each sequence.
