Cat Cancer Study May Benefit Pets and People

An international study mapped genetic changes in cancers from almost 500 domestic cats across five countries. Researchers found that many genes that drive feline tumors are also involved in cancers in people and dogs. The findings may help veterinary medicine and human cancer research, though they do not establish a ready-made treatment.
The clearest example involved mammary, or breast, tumors. FBXW7 was the most common driver gene in the cat mammary samples, and more than half carried a mutation in it. In people, mutations in FBXW7 are associated with a worse prognosis in breast cancer. Similarities appeared in several other cancer types too.
Scientists tested chemotherapy drugs on cat tumor tissue. Some drugs were more effective in samples with the mutated FBXW7 gene. However, this result came from tissue in a laboratory; it does not show that the drugs will work in living cats or humans. Clinical research would be needed to answer that question.
Cats naturally develop cancer and often share environments with people, so they may help researchers explore how genes and surroundings interact. The study also created a genetic resource for future work. In a two-way approach sometimes called One Medicine, knowledge from veterinary studies could inform human research, while treatments developed for people might eventually be evaluated for pets. Both possibilities remain areas for further study.
