Based on the OPTIMA trial, more than two-thirds of people with clinically high-risk breast cancer may safely avoid chemotherapy

The OPTIMA trial provided evidence that the Prosigna test can be used to predict chemotherapy benefit for people with HR+ breast cancer.

The OPTIMA results were reported by news outlets in the US and UK.*

The people who said yes

4,429 people joined OPTIMA across six countries. Because they said “yes” doctors can better support personalized chemotherapy decisions and make sure that the right treatment is given to the right patients.

"If I had to have chemotherapy, I probably would have had to stop working."

Aileen and her husband run a dry-cleaning business, working six days a week. When she was diagnosed with stage three breast cancer, one of her first worries was what treatment would mean for their livelihood. Then she was invited to join OPTIMA.
