Will you offer single fraction SBRT for pulmonary oligometastases?

We use single fraction radiation frequently for most peripheral lung metastasis.

In addition to TROG 13.01/SAFRON-II (randomized to 48 Gy/4 fx versus 28 Gy/1 fx, with the important footnote that dose was prescribed for 99% PTV coverage rather than the typical 95%), two other randomized trials - RTOG...

Yes. I recommend that small lung oligo mets be treated with SBRT. This is based on the RTOG 0915 trial, though I do not yet have abundant experience with this approach.
