Many dogs are diagnosed each year with cancer, a debilitating condition that leads to suffering, early death and euthanasia. Mast cell tumours (MCTs) are one of the most commonly diagnosed skin cancers in dogs. This particular type of cancer clinically mimics other skin growths and has an unpredictable biological behaviour, rendering treatment a challenging task for veterinarians. There is also a need for improved accuracy in the diagnostics of MCT, especially the most common type, grade II tumours, as up to 80% of them are biologically unpredictable, making treatment difficult.

Untreated disease, particularly grade II and III tumours, can spread to other organs if left untreated, and typically results in death within 6 months.

Some breeds, such as the Boxer and Boston terrier, are overrepresented in MCT cases examined in the US and UK, suggesting a genetic component to the risk of developing this cancer. Rayson Tan, a post-graduate PhD student in the Faculty’s canine genomics program, has been awarded an international Veterinary Student Scholars award by the Morris Animal Foundation (USA) to study the prevalence of MCT in the Australian dog population.

The study will also characterise the molecular basis of MCT and examine how this varies between breeds.
