Introduction: Lung cancer is the second most frequent malignancy worldwide, but its aetiology is still unclear. Inflammatory cytokines and Th cells, including Th17, are now emerging as being involved in NSCLC pathways, thus postulating a role of IL-17 in tumour angiogenesis by stimulating the vascular endothelial growth factor and the release of nitric oxide. Despite the fact that many biomarkers are used for chest malignancy diagnosis, data on FeNO levels and inflammatory cytokines in NSCLC are still few.

Moreover, obesity has important implications regarding technical issues and the risks associated with surgical interventions. Nevertheless, there is a lack of evidence assessing the influence of obesity on video-assisted thoracic surgery (VATS) lobectomy results.

This study analysed the results in non-thymomatous MG patients treated at our institution using an extended transcervical access with partial upper sternotomy (TC-US), in order to describe cumulative incidence of remission and its predictors.
Methods: In the period 1988-2012, 215 non-thymomatous MG patients underwent thymectomy using the TC-US approach.
Inflammation mediated by the immune system is known to be important in carcinogenesis and, specifically, T helper 17 cells have been reported to play a role in tumor progression by promoting neo-angiogenesis. The aim of this study was to investigate whether inflammatory cytokines and vascular endothelial growth factor (VEGF) levels in exhaled breath condensate (EBC) and in serum were related to tumor size in patients with non-small cell lung cancer (NSCLC). Il-6, IL-17, TNF-α and VEGF levels were measured in EBC and serum of 15 patients with stage I-IIA NSCLC and in 30 healthy controls by immunoassay.
