ESTRO meets Asia 2024

To minimize treatment variability among clinicians and improve the quality of radiotherapy for NPC patients worldwide, an International Guideline for the delineation of CTV for NPC, based on the consensus among international experts, was published in 2017. This has served as a valuable reference for the international community. With the accumulation of knowledge and technological advances in imaging, there is increasing data on the patterns of local and nodal extension. Furthermore, emerging data on locoregional control and survival rates support attempts with appropriate reduction in treatment volume and radiation dose. The objective of the current project is to review all updated data and existing guidelines from major organizations to re-evaluate our International Guideline and explore the possibility of achieving more precise coverage. Our Working Group consists of investigators from various regions, including Asia (China, Hong Kong, Korea, Singapore, Taiwan), Australia, North America (Canada, United States), Europe (Belgium, Denmark, France, The Netherlands, Turkey, United Kingdom), and the Middle East (Saudi Arabia). Initial survey reveals marked variation in practice among the experts. This collaboration provides a valuable platform for extensive exchange of opinions on various contentious issues, to reach a consensus on the best possible recommendations for CTV contouring in NPC.

Summaries of our systematic review and building of expert consensus will be presented. This will be important for achieving the ultimate goal of achieving maximum locoregional control with minimal toxicities.

Local recurrence of nasopharyngeal carcinoma: re-irradiation, immunotherapy, surgery?

Abstract

Nasopharyngeal carcinoma (NPC) is a distinct type of head and neck cancer, endemic in certain parts of Asia, and characterized by its association with the Epstein-Barr virus (EBV). Despite advances in radiotherapy and chemotherapy, local recurrence remains a significant challenge, occurring in up to 10-20% of patients post-primary treatment. This lecture explores the multifaceted approach to managing locally recurrent NPC, focusing on re irradiation, immunotherapy, and surgical interventions.
