EOT indicates 8 wk after completion of ISRT.
PET-negative response was defined as Deauville score 1 to 3.
For 1 patient, repeat PET scan remained positive, but subsequent biopsy demonstrated granulomatous inflammation consistent with sarcoid. For the second patient, repeat PET after 2 mo was negative (Deauville 3). Thus, both patients achieved a complete response.
