El Camino Health is First in California to Offer Cancer Patients Innovative Ethos™ Adaptive Intelligence™ Radiation Technology

Adaptive radiation therapy uses artificial intelligence to provide more precise treatment in real time, reduces damage to healthy tissue

Mountain View, Calif. — June 8, 2021 — El Camino Health is now one of just five in the U.S. and the first health system in the state of California to offer cancer patients an innovative adaptive radiation therapy called Ethos™. The advanced radiation oncology technology, created by Varian, uses artificial intelligence (AI) to create customized cancer-fighting treatment plans in minutes — a process that traditionally takes days to develop.

"The speed, precision and accuracy of this new technology is reshaping how we fight cancer," said Dr. Robert Sinha, director of the Center for Advanced Radiotherapy and Cyberknife Radiosurgery at El Camino Health. "We've never had the ability with radiation treatment to look inside the body and see what’s changing in real time, until now. And that capability is monumental when it comes to better treatment."

Ethos is the only technology that can customize radiation treatment plans in real time based on individual patient needs and anatomical changes. It does this by taking high-resolution images of the target — usually a tumor — to inform the best course for care, making necessary changes in minutes instead of days.

While the non-invasive Ethos technology can be used to treat many types of cancer, it is best suited for cancers that commonly change during treatment, such as prostate, lung and colorectal cancers. Because of the precise targeting of Ethos treatment, patients are far less likely to experience damage to surrounding healthy tissue.

El Camino Health's cancer radiation therapy program offers leading-edge radiation treatment options that are typically found exclusively in large academic institutions. It takes an integrated approach to care with a team of oncology nurse navigators, nutritionists, psychologists and social workers. A pioneer in the field, El Camino Health has been the first in the state or region to implement a variety of innovative services for treating prostate cancer, recurrent brain tumors, skin cancer and more.
