Plain-English summary
This study looked at 469 cases of oral and throat cancers in dogs, cats, horses, and cattle that were reported between 1964 and 1974. Most of these cases, about 84%, were found in dogs, with melanoma being the most common type of cancer in them. In cats and horses, squamous cell carcinoma was more frequent. The research found that older dogs were more likely to develop melanoma compared to other types of cancer, and male dogs had a higher risk of developing both melanomas and fibrosarcomas than females. Certain breeds like German Shorthaired Pointers and Golden Retrievers were at a higher risk, while Dachshunds and Beagles had a lower risk. Overall, the findings suggest that the risk factors for these cancers vary by breed and sex, but the treatment outcomes were not discussed in this study.
Abstract
Four hundred sixty-nine oral-pharyngeal malignancies diagnosed in dogs, cats, horses, and cattle and submitted to the Viterinary Medical Data Program between March 1, 1964, and Dec 31, 1974, were analyzed. Of these cases, 84% were in dogs. The most frequent oral-pharyngeal cancer in dogs was melanoma; in cats and horses, it was squamous cell carcinoma. In dogs, the risk of developing melanoma increased more with age than did the risk of developing squamous cell carcinoma and fibrosarcoma. Male dogs had significantly greater risk of developing fibrosarcomas and melanomas than did female dogs. The German Shorthaired Pointer, Weimaraner, Golden Retriever, Boxer, and Cocker Spaniel breeds had significantly higher risk and Dachshunds and Beagles had significantly lower risk, as compared with all breeds combined. There was no significant difference between observed and expected numbers of tonsillar carcinomas diagnosed at veterinary colleges located in small urban areas (less than 50,000 persons) as compared with large urban populations (greater than 500,000).
