Breath Analysis for Evaluation of Radiation Exposure in Lung Cancer Patients Treated With Radiation

June 30, 2016 updated by: Stanford University

Breath Analysis for Evaluation of Radiation Exposure in Lung Cancer Patients Treated With Radiation: A Feasibility Study

Patients treated with radiation therapy for lung tumors can experience inflammation after treatment. This study hopes to evaluate the use of breath analysis to evaluate changes in the composition of exhaled breath in patients undergoing radiotherapy. If changes can be detected, this may ultimately serve as biomarkers for identifying patients at highest risk for radiation-induced lung injury (radiation pneumonitis).
