Transforming Canine Cancer Diagnosis: The Role of AI in Mitosis Detection

The diagnostic landscape of canine Soft Tissue Sarcoma (cSTS), including Perivascular Wall Tumours (cPWTs), is on the brink of a significant transformation. Traditionally challenged by variability in mitosis counting—a critical factor in tumor grading—veterinary pathology is now leveraging artificial intelligence (AI) to usher in a new era of precision and standardisation.

Bridging the Gap with AI

Mitosis counting, essential for the histological grading of cSTS, suffers from inter- and intra-observer variability, complicating the accurate diagnosis and treatment planning for canine patients. However, a novel study employing a pre-trained Faster R-CNN model demonstrates the potential of AI to revolutionize this process. By incorporating veterinary pathologists in the AI training loop, the study not only harnesses the power of deep learning but also retains the invaluable insights of human experts.

A Collaborative Approach to Precision

The study’s methodology reveals a two-step annotation process, where pathologists initially annotate mitosis candidates, which are then refined through the AI model’s identification of false positives. This collaborative process enhances the dataset’s accuracy, with the AI model achieving an F1-score of 0.75. Such a score signifies a competitive edge in the domain of canine mitosis detection, showcasing the potential of AI to achieve reproducible and reliable assessments in histopathology.

The Future of Veterinary Pathology

This pioneering research marks a significant step toward integrating AI into veterinary pathology, offering a more standardised approach to diagnosing cSTS. The adaptive thresholding method employed further tailors the AI model’s sensitivity and specificity, aligning closely with the expert judgment of veterinary pathologists. This study not only highlights the feasibility of automating complex diagnostic tasks but also opens avenues for further exploration of AI applications across various histopathological analyses.
