Roche announces the release of its newest artificial intelligence based digital pathology algorithms to aid pathologists in evaluation of breast cancer markers, Ki-67, ER and PR

- Roche introduces three artificial intelligence (AI)-based, deep learning image analysis Research Use Only (RUO) algorithms developed for breast cancer, which is the second most common cancer in the world with an estimated 2.3 million new cases in 2020(1) and the most common cancer in women globally(1,2)

- Manual methods for quantification of the breast cancer markers can be time consuming and have reported significant interobserver variability(2,3), which can impact decision making to determine patient therapy

- Artificial intelligence (AI) advances and growing digitisation of pathology are a promising approach to meet the demand for more accurate detection, classification and prediction of patients with breast cancer(4,5)

TUCSON, Ariz., Dec. 7, 2021 /PRNewswire/ -- Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced the research use only (RUO) launch of three new automated digital pathology algorithms, uPath Ki-67 (30-9), uPath ER (SP1) and uPath PR (1E2) image analysis for breast cancer, which are important biomarkers for breast cancer patients. Breast cancer is the second most common cancer in the world with an estimated 2.3 million new cases in 2020¹ and is the most common cancer in women globally¹^,². These new algorithms complete the Roche digital pathology breast panel of image analysis algorithms.

uPath Ki-67 (30-9) image analysis, uPath ER (SP1) image analysis and uPath PR (1E2) image analysis for breast cancer use pathologist-trained deep learning algorithms to enable quick calculation of Ki-67, ER and PR tumour cell nuclei positivity. This includes a whole slide analysis workflow with automated pre-computing of the slide image prior to pathologist assessment, and a clear visual overlay highlighting tumour cells with and without nuclear staining. uPath Ki-67 (30-9) image analysis, uPath ER (SP1) image analysis and uPath PR (1E2) image analysis for breast cancer produce actionable assessments of scanned slide images that are objective and reproducible, aiding pathologists in quantification of these breast cancer markers.

Intended for use with Roche's high medical value assays and slides stained on a BenchMark ULTRA instrument using ultraView DAB detection kit, the uPath Ki-67 (30-9) image analysis, uPath ER (SP1) image analysis and uPath PR (1E2) image analysis algorithms are ready-to-use and integrated within Roche's uPath enterprise software and NAVIFY^® Digital Pathology, the cloud version of uPath. These algorithms are for Research Use Only. Not for use in diagnostic procedures.

"Roche is committed to the expansion of digital pathology solutions to address unmet medical needs and breast cancer diagnostics is a key opportunity area. Innovations like image analysis algorithms have the potential to impact patient care by increasing the information available to pathologists and enhancing diagnostic confidence," said Jill German, Head of Roche Diagnostics Pathology Customer Area.

In December 2021, Roche will be presenting an abstract (# P1-02-17) on our artificial intelligence, deep learning development of our breast panel RUO algorithms at the San Antonio Breast Cancer Symposium, which features the latest research and development on breast cancer research.

About Roche Digital Pathology

As the leading provider of pathology lab solutions, Roche is delivering an end-to-end digital pathology solution from tissue staining to producing high-quality digital images that can be reliably assessed using automated clinical image analysis algorithms.

Whole slide imaging combined with modern artificial intelligence (AI)-based image analysis tools have the potential to transform the practice of pathology. The use of AI and deep learning methods to interpret whole slide images in digital pathology enables pathologists to derive novel and meaningful diagnostic insights from tissue samples. AI-based image analysis automates quantitative tasks and enables fast, repeatable evaluation of information-rich tissue images that are sometimes difficult to interpret manually. AI-based image analysis uncovers aspects that are invisible to the human eye and reduces the risk of human error. Patients, whose tissue samples are analysed using AI-based image analysis, can benefit from a faster and more accurate diagnosis with IVD products. The insights gained from these analyses can help pathologists determine the best treatment option for cancer patients.

Roche offers two deployment options for its uPath software: an on-premise solution and a cloud solution, marketed as NAVIFY Digital Pathology. The VENTANA DP 200 slide scanner and Roche uPath enterprise software are CE-IVD marked for in-vitro diagnostic use and are available in the U.S. for Research Use Only (RUO). Not for use in diagnostic procedures. Image analysis algorithms developed by third-party entities and their utilisation are the responsibility of the third party provider.
