To develop expert consensus statements on multiparametric dose prescriptions for stereotactic body radiotherapy (SBRT) aligning with ICRU report91. These statements serve as afoundational step towards harmonizing current SBRT practices and refining dose prescription and documentation requirements for clinical trial designs. Based on the results of aliterature review by the working group, atwo-tier Delphi consensus process was conducted among 24physicians and physics experts from three European countries. The degree of consensus was predefined for overarching (OA) and organ-specific (OS) statements (≥ 80%, 60-79%, < 60% for high, intermediate, and poor consensus, respectively). Post-first round statements were refined in alive discussion for the second round of the Delphi process. Experts consented on atotal of 14OA and 17OS statements regarding SBRT of primary and secondary lung, liver, pancreatic, adrenal, and kidney tumors regarding dose prescription, target coverage, and organ at risk dose limitations. Degree of consent was ≥ 80% in 79% and 41% of OA and OS statements, respectively, with higher consensus for lung compared to the upper abdomen. In round2, the degree of consent was ≥ 80 to 100% for OA and 88% in OS statements. No consensus was reached for dose escalation to liver metastases after chemotherapy (47%) or single-fraction SBRT for kidney primaries (13%). In round2, no statement had 60-79% consensus. In 29of 31statements ahigh consensus was achieved after atwo-tier Delphi process and one statement (kidney) was clearly refused. The Delphi process was able to achieve ahigh degree of consensus for SBRT dose prescription. In summary, clear recommendations for both OA and OS could be defined. This contributes significantly to harmonization of SBRT practice and facilitates dose prescription and reporting in clinical trials investigating SBRT.
