Cardiac Dose and Survival After Stereotactic Body Radiotherapy for Early-stage Non-Small-cell Lung Cancer

In our cohort, cardiac dose was not a predictor of OS after lung SBRT, despite a subset of patients receiving high maximum cardiac doses. The findings from our limited cohort showed that high doses to small volumes of the heart appear safe. Analyses of larger patient cohorts with longer follow-up durations are needed to better delineate the safe cardiac DVH constraints for SBRT.
