Plain-English summary

A 10-year-old male Shetland sheepdog was diagnosed with a testicular tumor, which is a type of cancer that can occur in dogs. In a study of canine cancer cases, it was found that certain breeds, like Shetland sheepdogs and Collies, are more likely to develop these tumors, particularly Sertoli cell tumors. The average age for diagnosis was around 10 years, but Sertoli cell tumors were often found in younger dogs, around 8.6 years. Treatment options typically include surgery to remove the affected testicle, and many dogs recover well after this procedure.

Abstract

Histologically verified tumours submitted to the Norwegian Canine Cancer Register from 1990 to 1998 were studied (n=14,401). The proportion of testicular tumours (n=345) was 2.4%, and the breakdown of histological tumour diagnoses is presented. The frequency of the most common histopathological types was 33% interstitial (Leydig), 26.4% Sertoli and 33.9% seminomas/germ cell tumours. The average age at diagnosis was 10 years, but was significantly lower for Sertoli cell tumours (8.6 years) than for the other tumour types. Following a histopathological re-evaluation, 22.5% of the original tumor diagnoses were modified. Proportional morbidity ratios were calculated and individuals from the breeds Shetland sheepdog and Collie were five times more likely to have testicular tumours than the overall average for the registry. Breed differences in the distribution of histopathologic types were observed. Shetland sheepdog and Collie were most commonly diagnosed with Sertoli cell tumours, while all tumours from Norwegian elkhound in this material were seminomas.
