Visiopharm supports urgent call for improved quality assurance in immunohistochemistry with AI-based software tools

Visiopharm, a leading innovator in AI-driven Precision Pathology, acknowledges the significance of the recent editorial by Barbarajean Magnani and Clive R. Taylor published in Archives of Pathology and Laboratory Medicine, which calls for the regulation of clinical IHC as an assay rather than a stain. The authors highlight the need for more rigorous methods of analytic standardization, the importance of integrating pre-analytic, analytic, and post-analytic phases in a total test approach, and the necessity of a shift in mindset from viewing IHC as a stain to treating it as an assay. This is further supported by Dylan Miller in his editorial in the same journal, in which he points out that the CAP IHC resource committee is working to advance these principles, and that new formats and approaches are being explored for future survey.

We fully concur with the urgency of these points, which has also guided Visiopharm’s development of our AI-driven software tools, Qualitopix^TM and Oncotopix^®, over more than a decade. They are developed specifically to address many of these challenges, especially related to the evaluation of reproducibility of the analytical and post-analytical phases.

“The editorial by Magnani and Taylor underscores the critical need for improved quality assurance in IHC. Visiopharm’s development of Qualitopix, a state-of-the-art AI-based software solution that measures day-to-day staining consistency based on standardized and digitized control slides and provides Levey-Jennings plots for Class II IHC, is a significant step towards meeting the need outlined in the editorial”, stated Prof. Mogens Vyberg, Aalborg University, who is on the Scientific Advisory Board of Visiopharm.  The NordiQC IHC proficiency scheme was co-founded by Mogens Vyberg, the former director, and Søren Nielsen, the current director. NordiQC has contributed significantly to standardization of IHC by both the establishment of the proficiency scheme, but also by extended international scientific engagements and collaboration with other IHC stakeholders.

In addition, Oncotopix provides fully automated AI-based decision support for Class II IHC markers, such as ER, PR, HER2, Ki67 and PD-L1. Prof. Ralf Huss, University Hospital Augsburg, a recognized expert in pathology and Chairman of the Scientific Advisory Board of Visiopharm, comments, “Oncotopix’s ability to automate the analysis process and provide comprehensive reports on both the patient-specific analysis and the IHC control represents a major advancement in the field. This tool aligns with the vision expressed in the editorial and has the potential to significantly improve the accuracy and consistency of IHC results, reducing the risk of errors that could impact patient care. Also, such tools can help us avoid unnecessary re-testing and waste of precious material, as well as reduce costs and time in the conventional workflow to cope with limited human resources.”

“As the CEO of Visiopharm, I am proud of our team’s dedication to innovation and quality in the field of AI-driven Precision Pathology. We are committed to addressing the urgent needs that are expressed in the editorial and beyond. We believe that our AI-based tools, Qualitopix and Oncotopix, are essential for improving the quality and reliability of IHC testing, with quantitative quality control being the missing piece in modern biomarker assessment. Combining the precision with spatial information will enable Precision Pathology, and the beginning of a new era of precision oncology. We are very proud to collaborate on this vision with prominent organizations, such as NordiQC and UKNEQAS that both play instrumental roles in upholding standards in this field. Also, we are collaborating with leading providers of standardized and validated controls and calibrators that are used with Qualitopix, and, as pointed out in the editorial by Magnani and Taylor, these calibrators and controls required for day-to-day quality assurance exist already today”, stated Michael Grunkin.
