The Gustave Roussy Prize
Since 2025, the Gustave Roussy Prize has been awarded annually to a researcher for major scientific discoveries in oncology that have had a direct impact on patient care around the world.
A Tribute to Professor Gustave Roussy and the Institute’s 100th Anniversary
The Gustave Roussy Prize was established to commemorate the 150th anniversary of his birth and the centennial of the institute he founded. It thus pays tribute to this eminent professor. In fact, in 1921, Professor Gustave Roussy revolutionized cancer treatment by opening, for the first time, clinics dedicated exclusively to people with tumors. More than 100 years later, Gustave Roussy is the leading center for oncology in France and Europe and ranks among the best in the world.
