Researchers launch largest open-source pet 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 canine and feline tumor database, with more than 1 million records compiled from veterinary diagnostic data. The new registry is designed to standardize fragmented pathology information so researchers can study cancer patterns across breeds, ages, sexes, and tumor types, including rare cancers that have been hard to analyze at meaningful scale. The team said part of the work is already feeding new research, including a 2026 paper in Veterinary and Comparative Oncology on four major canine tumors in the UK. (liverpool.ac.uk)
Why it matters: For veterinary professionals, a dataset of this size could improve how the field understands cancer risk in dogs and cats, especially where individual practices or referral centers only see small slices of the picture. It also builds on earlier Liverpool-led pathology registry work that normalized more than 109,000 tumors from 180,232 UK pathology records, showing how large-scale text mining can turn routine diagnostic submissions into usable epidemiologic evidence. And that kind of scale matters because other datasets have shown just how complex companion-animal cancer epidemiology can be: a 20-year UC Davis hospital study of 150,063 dogs and cats found cancer in 26,883 patients, with risk rising strongly with age, declining incidence over time in cats but stable incidence in dogs, and important interactions between age and sex-neuter status for sarcoma and carcinoma. At the same time, newer feline genomics work published in Science profiled 493 tumors across 13 cancer types and found recurrent driver mutations such as TP53, FBXW7, and PIK3CA that parallel human oncology, underscoring the registry’s potential value for comparative oncology as well as breed- and demographic-specific risk estimates.

What to watch: Watch for peer-reviewed studies from the registry, broader international data contributions, and any move to translate registry findings into breed-specific risk guidance or clinical decision support. It will also be worth watching whether registry-scale epidemiology starts linking up with precision-oncology efforts, including feline mutation mapping that could inform targeted therapy research and blood-based monitoring approaches such as immune-signature testing in canine lymphoma.
