Researchers launch largest open-source dog and cat tumor database

Researchers at the University of Liverpool and the University of Las Palmas de Gran Canaria say they’ve built the world’s largest open-source database of canine and feline tumors, combining more than 1 million records into a single research resource. The project expands earlier registry work from the Small Animal Veterinary Surveillance Network, or SAVSNET, which previously described about 109,895 tumors drawn from 180,232 electronic pathology records submitted by three UK diagnostic laboratories. The new effort is designed to make large-scale patterns in breed, tumor type, age, sex, and geography easier to study, including rare cancers that are hard to analyze in smaller datasets. It also arrives as comparative oncology is gaining momentum across species, including new feline genomics work published in Science that profiled 493 cat tumors across 13 cancer types and found substantial overlap between feline and human cancer drivers such as TP53, FBXW7, and PIK3CA.

Why it matters: For veterinary professionals, the value is less about a headline number and more about what a dataset this large can unlock: better epidemiology, stronger breed- and demographic-risk signals, and a more practical evidence base for comparative oncology. Liverpool’s team says the registry can help surface patterns that were previously hidden in fragmented pathology data, while the underlying SAVSNET model was built specifically to turn routine diagnostic reports into a searchable, research-ready surveillance tool. That could support earlier recognition of higher-risk patients, sharper client counseling for pet parents, and better study design for oncology research. It also fits a broader shift toward precision oncology in companion animals, where large registries can complement genomic studies and treatment-response work, such as recent reports linking feline mammary tumor mutations to human breast cancer biology and blood-based immune signatures in dogs with lymphoma to treatment outcomes.

What to watch: Watch for more peer-reviewed analyses from the registry, including breed- and tumor-specific studies, and for whether the database evolves into a more widely used clinical decision-support and surveillance tool. Another key question is whether registry-scale epidemiology will begin to connect more directly with emerging genomics and biomarker work in dogs and cats, helping move veterinary oncology from broad population patterns toward more targeted risk assessment and treatment planning.
