Mass Spectral Fingerprinting in Lung Cancer

Active, not recruiting

• Conditions: Lung Cancer

• Registration Number: NCT02781857

Primary Outcome Measures

Name	Time	Method
Concentration of volatile organic compounds (VOCs) in the exhaled breath will be analysed using mass spectrometry	1 day, single measurement	The primary outcome will be the lung cancer specific mass spectrometric profile of VOCs of exhaled breath analysis (markers of lung cancer in exhaled breath).

Secondary Outcome Measures

Name	Time	Method
Group A: Concentration of volatile organic compounds (VOCs) in the exhaled breath will be analysed using mass spectrometry before and after lung cancer surgery	Group A: 2 measurements on 2 different days; Day 1: 1. measurement (before surgery), Day 2: (6-12 weeks after surgery): 2. measurement	The acquired profiles of mass spectral VOCs before and after lung cancer surgery will be analysed for significant differences.
