Personalized Cancer Prevention Takes Center Stage During Clinical Research Week
Scheduled to begin on May 18, this year’s Gustave Roussy Clinical Research Week will focus on personalized cancer prevention and the essential role that clinical research plays in advancing it. Hosted by health journalist Odile Pouget, a dedicated webinar will be held on May 21 at 6:00 p.m., featuring experts from Gustave Roussy.

Every year in May, Gustave Roussy takes the opportunity to highlight clinical research, the cornerstone of access to innovation in oncology and essential for the development of new therapies and techniques to fight cancer more effectively.
This year, the various events planned will focus on the theme of personalized cancer prevention. Entitled “Toward Tailored Cancer Prevention: How Research Is Making a Difference,” this year’s event will feature:
- From May 18 to 24, an educational exhibition dedicated to clinical research on the Gustave Roussy outpatient floor.
- Thursday, May 21, at 6:00 p.m.: a webinar open to the general public, featuring experts from Gustave Roussy and moderated by Odile Pouget, a health journalist.
Prevention and Clinical Research
It is estimated that 40% of cancer cases worldwide are linked to modifiable and identifiable risk factors[1]. To address this issue, Gustave Roussy launched the Interception program in 2021, which offers various personalized prevention pathways. The goal? To intervene early with individuals at increased risk (genetic predispositions, tobacco, alcohol, etc.) through tailored support and follow-up, to reduce the risk of developing the disease and, if it does develop, to detect it as early as possible.
With a rise in cancer incidence projected for the coming decades[2], strengthening the role and effectiveness of prevention is becoming a major public health priority. Clinical research plays a fundamental role in meeting these objectives by identifying new predictive biomarkers. These biomarkers are signatures present in the body that can help identify individuals at increased risk of developing cancer years before the disease appears. The LEAH clinical study, led by Gustave Roussy, aims to identify new predictive biomarkers through the Interception program.
Clinical Research at Gustave Roussy
Clinical research is at the heart of Gustave Roussy’s mission. In 2025, 618 studies were underway there, including 516 therapeutic trials.
To better understand the objectives of clinical trials, the different types, how they are designed, or to understand the differences between Phase I, II, and III trials, visit the Gustave Roussy consultation area from May 18 to 24, where an educational exhibition will be held.
