Why Choosing Breast Cancer?

Because breast cancer is the most common cancer in women. In spite of major breakthroughs and the development of new drugs, some forms of breast cancer remain difficult to treat.

A Scientific Accomplishment You Are Proud of

My research has identified a new mechanism regulated by the CD73 enzyme, whereby cancer cells escape immunosurveillance (that is, the destruction by white blood cells). This discovery led to the development of new drugs that are currently the subject of clinical studies. My work also showed that treatment with Herceptin (breast cancer) can be improved when combined with an immunotherapy targeting the PD-1 molecule. This new treatment is also the subject of a clinical study.
