Cardiac and Great Vessel Toxicity with Single Fraction Stereotactic Body Radiotherapy in Early-Stage Lung Cancer

While cardiac events are relatively common in the medically inoperable SBRT population, they did not appear to be more common with tumors directly contacting major cardiovascular structures than for those with some separation. Most events could be attributed to medical causes other than SBRT. Further study is needed to clarify the potential role of radiation in events without direct explanation.
