PTCOG-AO: Where Ancient Wisdom Meets Modern Healing: PTCOG-AO 2026 in Chennai
September 4-6, 2026 | Chennai, Tamil Nadu, India
Chennai, the capital of Tamil Nadu on India’s south-eastern coast, has long been a centre of healing and learning. The ancient Tamil medical system flourished here, while the region’s great temples stand as testaments to architectural and scientific precision. Today, this vibrant metropolis, known both as the “Detroit of South Asia” and the “Gateway to South Indian Culture” is home to some of India’s most prestigious medical institutions, drawing patients from across South Asia and beyond for world-class cancer care.
The Particle Therapy Revolution Comes to India
Chennai will host the PTCOG-AO community as India stands at a pivotal moment in its particle therapy journey. With several proton therapy centres now operational or under development across India, this meeting comes at an opportune moment as the nation embraces advanced radiation oncology to serve its population of 1.4 billion people. The same precision that guided ancient Tamil architects now finds expression in modern particle therapy, delivering radiation with sub-millimetre accuracy.
What Awaits in Chennai
From September 4-6, 2026, the PTCOG-AO Chennai meeting will bring together the brightest minds in particle therapy from across Asia, Oceania, and the world. The scientific program will explore the cutting edge of proton and carbon ion therapy, featuring keynote presentations from international leaders, technical sessions on the latest clinical and physics advances, workshops for early-career professionals, and robust discussions on making particle therapy accessible to underserved populations, a topic of particular relevance in the Indian and broader Asian context.
The meeting will provide a unique platform to discuss region-specific challenges and innovations, from designing particle therapy facilities for high patient volumes to developing cost-effective treatment protocols. Clinical case presentations will highlight diverse patient populations and disease presentations characteristic of the Asian-Oceanic region, while industry exhibitions will showcase the latest technological advances in particle therapy delivery and treatment planning.
A Welcoming Destination
The meeting will be held along the scenic East Coast Road, a picturesque coastal route known for its serene beauty, pristine beaches, and tranquil atmosphere providing an ideal setting for focused scientific exchange and networking in a relaxed environment.
Chennai’s international airport offers excellent connectivity to major cities across Asia, the Middle East, and beyond, making it easily accessible for participants traveling from all corners of the PTCOG-AO region. September brings pleasant post-monsoon weather, with comfortable temperatures ideal for both scientific pursuits and cultural exploration.
For those planning to extend their stay, India offers one of the world’s most diverse travel experiences—from the grandeur of the Taj Mahal to the royal palaces of Rajasthan, from the lush rainforests of the Northeast to the white deserts of Kutch, from the serene backwaters of Kerala to the mighty Himalayas. Chennai itself serves as a perfect gateway to explore South India’s UNESCO World Heritage Sites, including the ancient shore temples of Mahabalipuram, the magnificent Brihadeeswara Temple in Thanjavur, and the temple city of Madurai.
Building Bridges, Advancing Care
The PTCOG-AO Chennai meeting represents more than a scientific conference, it is an opportunity to strengthen bonds across the Asian-Oceanic particle therapy community, to learn from each other’s experiences, and to collectively work toward making precision cancer care accessible to the millions who need it. As India’s particle therapy capabilities expand, the knowledge shared in Chennai will help shape the future of cancer treatment across one of the world’s most populous and diverse regions.
We invite abstract submissions across all aspects of particle therapy, from clinical outcomes and treatment protocols to medical physics innovations, from quality assurance methodologies to facility design considerations. Whether you’re a seasoned practitioner or an early-career researcher, your contributions will help chart the course for particle therapy in our region.
Detailed information on registration, abstract submission deadlines, accommodation options, and the full scientific program will be shared in the coming months. We encourage you to mark your calendars now and begin planning your journey to Chennai.
