Willingness of twelve radiation oncologists to omit radiotherapy to the prostate fossa (prostate fossa RT). Asked if they would consider omission of prostate fossa RT in a high-risk patient after completely resected (R0) prostate cancer with persisting PSA values (> 0.6 ng/ml). Possible disposition had to be scored and ranged from 1 (definitely yes) to 9 (definitely no). Most radiation oncologists were in favour of prostate fossa RT in case of PSMA positive lesions within the pelvis (left), a high disagreement existed in case of extrapelvic PSMA positive lymph node lesions as only finding in PET (right).
