Multi-institutional virtual peer review for reirradiation: dedicated workflow and one-year results

This study reports one-year results from multidisciplinary and multi-institutional virtual peer review meetings for reirradiation cases. A dedicated workflow supported collaborative decision-making, especially for complex treatments, and guided dose prescriptions and cumulative dose evaluations. The indication of reRT was disapproved for 19% of the cases, while the reRT dose prescription was suggested or modified for 45% of the validated indications. Results confirm feasibility and clinical value, fostering safer and more standardized reirradiation practices across institutions.
