Is the Exhaled Breath Temperature Sensitive to Cigarette Smoking?

The smoking habit is accompanied by an acute inflammatory response which follows tissue injury. It would be desirable to find a non-invasive inflammatory marker that would simplify the task of studying and monitoring smokers more simply and allow us to identify populations at risk of contracting Chronic Obstructive Pulmonary Disease (COPD). Today's expectations regarding research focus on issues ranging from inflammatory markers to those of exhaled breath temperature (EBT) are considerable.

Exhaled breath temperature in NSCLC: could be a new non-invasive marker?

The exhaled breath temperature (EBT) has been proven to be the expression of airways inflammation as well as of the increased vascularity. Although both these conditions characterize lung cancer pathogenesis, this is the first study where the EBT has been analysed in patients affected by non-small-cell lung cancer. The aim of this study was to verify whether and how the lung cancer being examined influences the EBT for possible future clinical implications.

Cigarette smoke and increased COX-2 and survivin levels in exhaled breath condensate of lung cancer patients: how hot is the link?

Unlabelled: One of the most current intriguing hypotheses on lung cancerogenesis envisages a role for inflammation as a possible trigger of both epithelial-mesenchymal transition and cancer development. Cigarette smoke has been suggested to be the main factor underlying the inflammation of the airways described in lung cancer patients. Cycloxygenase and survivin, a COX-2 dependent factor of apoptosis resistance, seem to play a key role in this regard.
