Researchers launch 1 million-record dog and cat tumor registry

CURRENT BRIEF VERSION: 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 pathology records into a single research-ready registry. The project, developed through Liverpool’s Small Animal Veterinary Surveillance Network, or SAVSNET, is designed to standardize data that has historically sat in separate private diagnostic labs, making it easier to study cancer patterns across breeds, tumor types, and species. Early reporting around the launch points to more than 150 tumor types and over 200 breeds represented, with one linked 2026 paper already using the registry to examine four major canine tumors in the UK. The timing also fits a broader shift in comparative oncology: separate recent feline genomics work published in Science profiled 493 cat tumors across 13 cancer types and found recurrent mutations in genes such as TP53, FBXW7, and PIK3CA, underscoring how larger, standardized animal cancer datasets can support cross-species cancer research rather than simple case counting alone.

Why it matters: For veterinary professionals, the significance is less about the headline number and more about what a harmonized registry can unlock: stronger epidemiology, better visibility into rare cancers, and more credible breed-, age-, and neuter-status associations than smaller, single-center datasets can provide. That matters in a field where cancer surveillance has remained fragmented for decades, and where recent reviews have argued that inconsistent reporting and limited standardization still constrain both clinical research and comparative oncology. It also matters because newer feline cancer studies are beginning to show exactly what better-scale data can reveal: mammary carcinoma in cats appears to share important genomic features with human breast cancer, including frequent FBXW7 and PIK3CA alterations, while naturally occurring cancers in pets may help inform precision oncology in both species. A larger, shared dataset could also improve how clinicians counsel pet parents about risk, referral decisions, and where evidence is still thin, especially for uncommon tumors and under-studied feline cancers.

What to watch: The next step is whether the registry expands to additional laboratories, adds stronger denominator data on the broader pet population, and translates into clinically useful risk tools rather than descriptive surveillance alone. Another question is how resources like this may connect with more molecular work, including feline oncogenomics and blood-based response markers in canine lymphoma, where recent research suggests circulating immune-gene signatures could eventually help predict which dogs are less likely to respond to newer chemo-immunotherapy regimens.
