Windsor Barra Hotel hosts the 11th IAOO World Congress from 5 to 8 May 2027. Its subject is oral, head and neck oncology. The programme brings together specialists working at different stages of a patient’s care, from diagnosis and treatment to recovery and life afterwards.

What areas are announced?
Scientific themes include oral and oropharyngeal cancer, HPV-related disease, immunotherapy, biomarkers and precision oncology. Reconstructive surgery, rehabilitation, molecular diagnosis, digital pathology and artificial intelligence also feature in the programme.
The meeting is intended for surgeons, medical and radiation oncologists, pathologists, dentists and other specialists. Discussions of supportive care and quality of life extend the programme beyond treatment itself. This is professional education and scientific exchange, rather than a medical consultation service.
