Welcome

We welcome all to the 38th Annual Meeting of the European Musculo-Skeletal Oncology Society and the 26th EMSOS Nurse and Allied Professions Group Meeting in our beautiful town of Estoril.

The meeting will open with a first full day, dedicated to residents, young researchers and doctors initiating in the field of Musculo-Skeletal Oncology, in our traditional Training Day.

Both the Training Day and the main meeting will focus on this year central theme: Multidisciplinary. Our goal is to explore the multidisciplinary management of patients from diagnosis to treatment, including the role of new technologies and advances in translational research.

This meeting offers EMSOS members and non-members, alike a unique opportunity to discuss and engage with the latest developments in our field, through crossfire sessions, case discussions between different centres, and efforts to build consensus among participants.

Portugal has a long tradition in academic education, alongside with an amazing and unique hospitality. We are confident that our time in Estoril will make for an unforgettable meeting and lasting memories.

Join us for an enriching opportunity to enhance your expertise in the field.
