Artificial IntelligenceStudy at Japan’s Kameda Medical Center Demonstrates Excellent Outcomes for Ibex’s AI-powered Solution in Diagnosing Prostate and Breast Cancer

Ibex Medical Analytics (Ibex), a global leader in AI-powered cancer diagnostics, and Kameda Medical Center (Kameda), a leading Japanese institute at the pinnacle of healthcare innovation, today announced the publication of a clinical study evaluating Ibex’s Galen™ platform, published in the peer-reviewed journal Pathology1, which demonstrated excellent outcomes in detecting cancer and other pathologies in prostate and breast biopsies. The artificial intelligence (AI)-powered platform has subsequently been deployed at Kameda and is now supporting their pathologists in routine practice, integrated with their Philips IntelliSite Pathology Solution.

“We were deeply impressed by Galen’s performance in the study, that based on our validation, clearly showed how Ibex can support our clinicians in improving diagnostic quality and efficiency, and as a result we have decided to implement it routinely,” said Prof. Junya Fukuoka, MD, PhD, Chair of the Department of Pathology at Kameda Medical Center, Chair of the Department of Pathology Informatics at Nagasaki University and the study’s primary investigator. “Interestingly, Galen identified both malignant and non-malignant findings previously undetected by pathologists and we are proud to have become the first pathology department in Japan to use digital pathology and AI routinely for primary cancer diagnosis, significantly improving our pathologists’ user experience and confidence.”

Cancer incidence in Japan is rising, with prostate and breast cancers being the most commonly diagnosed cancers in men and women respectively last year. As incidence grows and diagnosis becomes more complex in this era of precision medicine, accuracy is critical for enabling personalized and tailored therapies. This is further compounded by the global shortage of pathologists, resulting in unprecedented workloads, impacting diagnostic quality and turnaround time. Ibex helps overcome these challenges with AI-powered workflows and decision-support tools that pathologists use in their everyday practice.

The study, and subsequent publication authored by Kris Lami, MD, PhD, evaluated the performance of Ibex’s AI platform in detecting a broad range of pathologies in 100 breast and 100 prostate biopsies taken from a Japanese patient cohort. Ibex’s platform demonstrated excellent outcomes, showcasing its ability to accurately detect both cancerous and non-cancerous features. During the study, Galen Prostate demonstrated high accuracy in detecting prostate adenocarcinoma with an Area Under the Curve (AUC) of 0.988. The AI algorithm was also highly accurate in cancer grading, specifically differentiating between low and medium/high-grade Gleason scores with an AUC of 0.994, as well as in identifying perineural invasion. In several cases, Galen Prostate’s AI algorithm accurately identified higher Gleason scores than previously evaluated by a pathologist and unveiled previously undetected cancer, showcasing its potential to enhance diagnostic accuracy and reduce inter-observer variability. Similarly, Galen Breast showed high accuracy in detecting invasive breast cancer (AUC of 0.997) and in detecting ductal carcinoma in situ (DCIS) (AUC of 0.996), as well as in identifying other important pathologies, such as lymphovascular invasion.

“We are proud to announce the study outcomes and publication led by such a prestigious Japanese medical center, which come as an addition to successful studies of Ibex’s AI solutions recently presented by leading United States healthcare institutions across various tissue types,” remarked Dr. Manuela Vecsler, VP of Clinical and Scientific Affairs at Ibex Medical Analytics. “Galen is the most widely deployed AI technology in pathology, and we are excited to see it adopted in Japan and become the new standard in cancer diagnosis, helping clinicians improve patient care.”
