Baseline Pulmonary Function as a Predictor for Survival and Decline in Pulmonary Function Over Time in Patients Undergoing Stereotactic Body Radiotherapy for the Treatment of Stage I Non-Small-Cell Lung Cancer

Poor baseline pulmonary function did not predict decreased survival or pulmonary function after treatment. A statistically significant decrease in Dlco after treatment was seen, similar to decreases seen in studies delivering standard thoracic radiotherapy. We conclude that low pretreatment FEV1 and/or Dlco alone should not be used to exclude patients with NSCLC from treatment with SBRT.
