Abstract
In this study we undertook a comprehensive analysis of a Pet Tumour Registry of the Canary Archipelago (PTR-CA) in Spain to investigate the epidemiology of canine cutaneous round cell tumours. From a database of 2526 tumours collected from 2003 to 2020, we conducted a longitudinal analysis of the main trends in diagnosis, age, multiplicity and anatomical distribution as well as a case-control study comparing these cases with the contemporaneous canine population of the Canary Archipelago to analyse breed distribution. In line with former studies, we found histiocytomas mostly affect young dogs (2, IQR 1-5) and mast cell tumours affect middle-to-old dogs (8, IQR 6-10) with grade 1 affecting at younger ages (6.5, IQR 6-8) than both grade 2 (8, IQR 6-10 years) and grade 3 (9, IQR 7-11). Histiocytomas and plasmacytomas showed a similar anatomical distribution appearing mainly on the face, head and neck regions while mast cell tumours occur mainly on limbs and trunk. Higher risk for mast cell tumours and histiocytomas were found for Bulldog-related breeds such as Boxer (ORMCT = 23.61, CI95%: 19.12-29.15, ORHCT = 10.17, CI95%: 6.60-15.67), Boston Terrier (ORMCT 19.47, CI95%: 7.73-49.05, ORHCT 32.61, CI95%: 11.81-90.07) and Pug (ORMCT 8.10, CI95%: 5.92-11.07, ORHCT 7.87, CI95%: 4.66-13.28) while Chihuahua dogs showed significantly less risk (ORMCT 0.18, CI95%: 0.09-0.33, ORHCT 0.41, CI95%: 0.21-0.78). Notably, the Canarian Mastiff, a local breed, had a low risk of suffering from a mast cell tumour which raises the question of whether this relates to a genetic peculiarity of this breed or some husbandry and environmental factor.
期刊介绍:
Veterinary and Comparative Oncology (VCO) is an international, peer-reviewed journal integrating clinical and scientific information from a variety of related disciplines and from worldwide sources for all veterinary oncologists and cancer researchers concerned with aetiology, diagnosis and clinical course of cancer in domestic animals and its prevention. With the ultimate aim of diminishing suffering from cancer, the journal supports the transfer of knowledge in all aspects of veterinary oncology, from the application of new laboratory technology to cancer prevention, early detection, diagnosis and therapy. In addition to original articles, the journal publishes solicited editorials, review articles, commentary, correspondence and abstracts from the published literature. Accordingly, studies describing laboratory work performed exclusively in purpose-bred domestic animals (e.g. dogs, cats, horses) will not be considered.
