About Winter School

Join us January 27 – 30, 2026 in Niagara-on-the-Lake, Ontario, for keynote perspectives, site‑specific deep dives, industry‑focused plenaries, Canadian initiatives, and a national stakeholder dialogue ultimately culminating in a shared strategy for advancing reirradiation practice and research across Canada

The learning objectives for the school are to:

Describe the current international state of reirradiation, including key advances driven by global collaborative efforts
Evaluate commercial technologies for reirradiation and gain insight into vendors’ future development roadmaps
Identify ways Canadian centres can advance reirradiation, both independently and through partnerships
Formulate actionable next steps and collaborative strategies to advance the field within the Canadian context

Day 1 — Wednesday, January 27 — Opening Keynote & Welcome
State of the Science: ReCOG & ESTRO Perspectives (Panel)	Situate the goals within the broader international reirradiation research agenda advanced by ESTRO and ReCOG
Opening Keynote (ESTRO/ReCOG-endorsed)	Identify the key questions the Winter School aims to address over the following three days
Day 2 — Thursday, January 28 — Global State of the Field
Site-Specific Sessions (Brain & Spine, H&N, Breast, Thorax, Liver & Abdomen, Rectum & Pelvis, Cervix & Pelvis, Pediatrics)	Summarize key outcomes and knowledge generated through major international collaborative networks and trials in reirradiation Describe how international collaboration has shaped current clinical practice and research priorities; identify gaps in current evidence and emerging areas of investigation Articulate anticipated near-term developments and their potential impact on clinical practice
Radiobiological Modeling	Describe how radiobiological principles in reirradiation differ from de novo treatment, and identify key knowledge gaps in tissue recovery modeling
Registries & Trial Design	Identify how standardized registries and trial design can address current evidence gaps in reirradiation research Describe recent, robust registry and trial designs currently in use for reirradiation
Vendor Wishlist	Engage in dialogue with vendors about future product roadmaps and provide clinical input on the clinical tools needed to support reirradiation practice
Day 3 — Friday, January 29 — Innovation, Industry & Canadian Initiatives
Image Registration & Dose Mapping	Identify major reirradiation initiatives currently underway across Canadian centres
Clinical Workflows	Compare approaches, protocols, and resources across different provinces and institutions Discuss recent efforts to establish standardized reirradiation workflows and the rationale for their adoption
Technical Considerations & After Planning (Documentation & EMR)	Evaluate current methods, limitations, and reporting standards for image registration-based dose mapping
Technology Spotlight (Parts I & II)	Describe current commercial technologies and platforms designed to address reirradiation challenges
Canada in Focus: CPQR KQI reRT Standards, AROPAC, Ontario Thorax Consensus	Identify major reirradiation initiatives currently underway across Canadian centres
Day 4 — Saturday, January 30 — Stakeholder Dialogue and Path Forward
Project Gallery	Identify innovative reirradiation projects underway across Canadian institutions and agencies
Learning Reflections & Collaboration	Discuss key takeaways in small groups and identify how to apply them within their own institution
Charting the Path Forward	Synthesize insights from Days 1–3 to inform a national strategy to advance care of all Canadian reirradiation patients Engage constructively with multidisciplinary and multi-sector stakeholders to identify shared priorities in reirradiation Contribute to defining concrete, actionable next steps for advancing reirradiation practice and research in Canada
