Sarcomas are a rare and heterogeneous tumour group that can affect patients of all ages, and all sites in the body. Recent developments in molecular biology have led these tumours to be redefined, and led to the introduction of novel approaches to treatment. The speakers will review the impact of these developments in three distinct areas: gastrointestinal stromal tumours (GIST), soft tissue, and bone sarcomas. Their talks will span from tumour biology to patient management. The session will have broad appeal to scientists, pathologists, surgeons and oncologists.
