Breast Cancer: A Major Public Health Challenge

Breast cancer is a major public health issue, being the most frequent and deadliest cancer among women. Each year, it affects more than 2.3 million women worldwide. However, when detected early, breast cancer has a high chance of being successfully treated.

In this context, Paris Saint-Joseph Hospital, a leading reference center in oncology, has integrated Cleo Breast, the artificial intelligence solution developed by Primaa for breast pathology. This initiative represents an important milestone in leveraging AI to support breast cancer diagnosis within the hospital.

To better understand its role, Cleo Breast assists pathologists in analyzing digitized slides by automating essential tasks such as:

• Detecting and quantifying breast lesions
• Identifying prognostic factors such as mitoses
• Automatically detecting calcifications
• Detecting lymph node metastases

Compatible with the most widely used laboratory viewers, Cleo Breast integrates directly into existing workflows, enabling pathologists to improve efficiency and accuracy. It also helps reduce the turnaround time for biopsy pathology results, allowing for faster patient care.

The benefits of Cleo Breast are also highlighted by the experts using it:

« I am very excited to integrate the Cleo Breast AI algorithm into my daily practice in breast pathology. This allows us to build the future of breast pathology, where AI helps pathologists work faster and more consistently, ultimately benefiting patients, » says Dr. Elisabeth Russ, pathologist at Paris Saint-Joseph Hospital.

« Paris Saint-Joseph Hospital is a strong reference in oncology and in the fight against breast cancer. We are very proud to deploy Cleo Breast within the pathology department and to gradually integrate AI tools into medical practice, » explains Marie Sockeel, co-founder of Primaa and pathologist.

A Shared Commitment to Innovation

This deployment illustrates the shared commitment of Primaa and Paris Saint-Joseph Hospital to medical innovation and the continuous improvement of care for patients with breast cancer.

We warmly thank the teams at Paris Saint-Joseph Hospital for their trust and openness to innovation.
Together, we are shaping the future of breast pathology, where AI enables pathologists to work faster and more consistently, to the benefit of patients.
