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

This study has been completed.

Last verified: June 2016
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).

Condition Intervention
Lung Cancer Non-Small Cell Lung Cancer Small Cell Lung Cancer Procedure: Exhaled Breath Sampling

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Breath Analysis for Evaluation of Radiation Exposure in Lung Cancer Patients Treated With Radiation: A Feasibility Study

Further study details as provided by Stanford University:

Primary Outcome Measures:
  • Pre and post-radiation FeNO (fraction of exhaled nitric oxide) measurements [ Time Frame: Every 3 months for 1 year ]

Secondary Outcome Measures:
  • Pre and post-radiation CO (carbon monoxide), CO2 (carbon dioxide), and N2O (nitrous oxide) measurements and feasibility as the fraction of patients unable to give a breath sample. Adverse events are not expected but any that appear related to the breath [ Time Frame: 1 yr ]

Enrollment: 20
Study Start Date: August 2010
Study Completion Date: March 2012
Primary Completion Date: September 2011 (Final data collection date for primary outcome measure)
