Dear Colleagues,
On behalf of the PTCOG Executive Committee and the Local Organizing Committee, it is our great pleasure to invite you to Bangkok, Thailand, for the 65th Annual Conference of the Particle Therapy Cooperative Group (PTCOG 65) & 7th PTCOG-AO Meeting, taking place from 7–12 June 2027.
Our theme, “Advancing Particle Therapy Together,” reflects our shared commitment to pushing the boundaries of precision cancer care – uniting the world’s leading clinicians, physicists, radiobiologists, engineers, and industry leaders from all over the world in a common mission to improve outcomes for patients worldwide.
PTCOG 65 will feature a rich scientific program spanning the full spectrum of particle therapy, from cutting-edge radiobiology and AI-driven treatment planning to clinical evidence, adaptive radiotherapy, and global access initiatives. As with previous editions, the conference will open with a rich educational program, followed by three days of in-depth scientific sessions showcasing the latest research, clinical case studies, and strategic discussions across all disciplines of the field. We remain deeply committed to the inclusion of early-career researchers, diverse regional perspectives, particularly the Asian community, and active engagement from our scientific sub-committees.
Bangkok offers an inspiring backdrop for this gathering. It is a city where tradition and innovation coexist, fitting for a conference that honors the foundations of particle therapy while boldly pushing the boundaries.
Whether you are a seasoned expert or just beginning your journey in particle therapy, we warmly invite you to join us for a week of knowledge exchange, collaboration, and unforgettable experiences.
We look forward to welcoming you to Bangkok for PTCOG 65!
Warm regards,
Marco Durante
PTCOG President
