08. Light, wireless probes the size of a large pen have been developed to identify cancer cells and suspicious lymph nodes during surgery. The probes, which EPFL helped develop, are now being tested by surgeons at the University Hospital of Lausanne (CHUV) and across Europe. When surgeons remove a malignant tumor, they have to be sure to get all the cancer cells. Just as crucial, they have to determine whether the tumor has already sent micrometastases into the neighboring lymph nodes on the way to the rest of the body. EPFL, in partnership with Forimtech and the CHUV, developed two compact, light and wireless probes that help doctors with both of these tasks. The Gamma probe improves on similar devices already in use in radioguided surgery, while the Beta probe is a totally new type of device able to detect extremely small bits of cancerous tissue.
