A defined pathway with fee waivers and clear evidence steps would bring rigour without blocking progress.","summary":"Regulators and professional bodies define a staged pathway for radiotherapy techniques and fractionation innovations (not just machines): technical feasibility and dosimetry standards, early-phase toxicity studies with defined endpoints, randomised or registry-based comparative evaluation, and a clear route to guideline and reimbursement recognition, with regulatory fee waivers and scientific advice for academic sponsors. The machine is regulated as a device but the technique (dose, fractionation, target, adaptation strategy) is what determines outcomes, and it currently has no evidence pathway at all. Radiotherapy groups have called for this for years; making it official aligns academic sponsors, payers and regulators on what evidence is needed.","asOf":"2026-09-08","links":[{"label":"ESTRO","url":"https://www.estro.org/"}],"tags":[],"related":["idea-fund-flash-evidence-programme","idea-fund-adaptive-radiotherapy-evidence","idea-fund-radiotherapy-trials-infrastructure"],"cancers":[],"sections":[],"technologies":["flash-rt","mr-linac","sbrt","carbon-ion"],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":["michael-baumann","juergen-debus"],"bottlenecks":["b-surgery-radiation-innovation","b-regulatory-fragmentation"],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"hypothesis":"A defined pathway increases the proportion of new radiotherapy techniques entering clinical use with a prospective comparative study underway from a minority to a majority within four years, and shortens the time from first use to guideline recognition for techniques that prove beneficial.","rationale":"SBRT and hypofractionation spread for a decade on retrospective data before randomised trials confirmed benefit; FLASH and adaptive radiotherapy are following the same path.
