Donors' trust is essential. That is why we make sure to make the most of every euro entrusted to Gustave Roussy.

More than 24.8 million euros in donations and bequests were allocated to cancer research.

Your support has made it possible, in particular, to:

• funding for pediatric oncology research programs;
• the development of new therapeutic approaches, including cell therapies and antibody-drug conjugates;
• the launch of major scientific programs such as INTERCEPTION, CELL-ATTACK, LOCA-METS, and CLINICOBIOME;
• attracting the best international talent through chairs of excellence;
• funding for clinical trials that enable patients to gain faster access to therapeutic innovations.

Because, beyond medical treatments, every patient should be able to benefit from compassionate, personalized, and innovative care, more than 15.7 million euros in donations and bequests have been dedicated to patients and their quality of life.

Thanks to these donations and bequests, Gustave Roussy has been able to:

• renovate an entire floor dedicated to hematology;

In 2025, €6.1 million in donations and bequests were invested in the future Gustave Roussy research building. Scheduled to house nearly 60 research teams by 2028, this new building—spanning more than 30,000 square meters—will make it possible to:

• double current research capacity;
• foster collaboration among scientists;
• to accelerate the transfer of discoveries to patients;
