Table 2: Areas of divided opinion (agreement < 65%), major agreement (65% < agreement < 80%), and consensus (agreement > 80%) in section 1 and 2 of the questionnaire at the end of round II.

Conclusion The present ESTRO ACROP study represents one of the first efforts to achieve consensus on some critical aspects in SBRT in oligometastatic RCC, which is currently a controversial topic. This ESTRO ACROP consensus may serve as practical guidance for the use of SBRT in oligometastatic RCC, and indicate the main areas where disagreement still persists, possibly guiding future efforts in filling knowledge gaps.
