Lung cancer is a frequent cause of cancer-related deaths in the world. There is no valid
screening process and this limits its detection to the late stages, with consequently high …

Corporal mechanisms attributed to cancer, such as oxidative stress or the action of
cytochrome P450 enzymes, seem to be responsible for the generation of a variety of volatile …

Background Many volatile organic compounds (VOCs), principally alkanes and benzene
derivatives, have been identified in breath from patients with lung cancer. We investigated …

There has been an increased focus on the development of non-invasive biomarkers capable
of accurately identifying lung cancer early in its course and characterizing the nature of the …

The presence of certain volatile biomarkers in the breath of patients with gastric cancer has
been reported by several studies; however, the origin of these compounds remains …

Volatile organic compounds (VOCs), are mainly blood-borne and are exhaled via the blood–
breath interface in the lungs. VOCs diffuse across the pulmonary alveolar membrane from …

Exhaled breath and gastric-endoluminal gas (volatile products of diseased tissues) contain
a large number of volatile organic compounds, which are valuable for early diagnosis of …

Noninvasive breath analysis may provide valuable information for cancer recognition if
disease-specific volatile biomarkers could be identified. In order to compare nondiseased …

Breath-gas analysis has demonstrated that concentration profiles of volatile organic
compounds (VOCs) could be used for detecting a variety of diseases, among them gastric …

Currently, there is a trend towards personalized medicine in lung cancer care, with
individualized treatment for patients (based on the molecular specification of the lung cancer …
