Incidence of high-risk radiological features in patients without local recurrence following SABR for early stage non-small cell lung cancer

Local control rates are high using stereotactic ablative radiotherapy (SABR) for early stage non-small cell lung cancer. However, subsequent lung fibrosis can be difficult to distinguish from tumor recurrence. We investigated the incidence, and patterns of change in high-risk radiological features (HRF's) in patients known to have no local recurrence.
