Data from the Danish Veterinary Cancer Registry on the occurrence and distribution of neoplasms in dogs in Denmark

Abstract

From May 15, 2005 to April 15, 2008, 1878 cases of neoplasms in dogs were reported to the web-based Danish Veterinary Cancer Registry. The proportions of malignant (38 per cent) and benign (45 per cent) tumours were similar. The most common malignant neoplasms were adenocarcinomas (21 per cent), mast cell tumours (19 per cent) and lymphomas (17 per cent). The benign neoplasms most commonly encountered were lipomas (24 per cent), adenomas (22 per cent) and histiocytomas (14 per cent). Skin (43 per cent) and the female reproductive system including mammary tissue (28 per cent) were the most common locations of neoplasia. There was a distinct breed predisposition for tumour development, with a high standard morbidity ratio (indicating a higher risk of cancer) for boxers and Bernese mountain dogs. A standard morbidity ratio below 1 was observed in German shepherd dogs and Danish/Swedish farm dogs, suggesting a lower risk of cancer in these breeds.

A longitudinal study of ABC transporter expression in canine multicentric lymphoma

“…The diagnosis 'Fat; possibly lipoma' was clearly the most commonly diagnosed benign lesion in the cytological data-set, which was also the case in a study in Denmark [19] and the UK [34]. These last studies consider a general dog population instead of one particular breed and both include cases diagnosed by both methods and not just histology.…”

“…Clear evidence exists for a breed-related predisposition to specific cancers, like histiocytic sarcomas in Bernese Mountain dogs [10,13] and Flatcoated retrievers, [11] anal sac carcinomas in the English Cocker Spaniel [12,14] and hemangiosarcomas in German Shepherd dogs [15]. For the Golden retriever, an increased risk for the development of cancer in general has been reported by some [16,17], but not all studies [18,19]. Also, there are reports on an increased risk for specific types of cancer in Golden retrievers such as mast cell tumours (MCT) [12,20] melanomas [21] and non-Hodgkin lymphomas (NHL) [12,22,23] and suggestions of a predisposition to soft tissue sarcomas (STS) [24][25][26][27].…”

Immunohystochemical Study of the Intestinal Stromal Tumors in Dogs-7 Cases and Review of the Literature

“…Despite this high frequency in the percentage of leiomyosarcomas from the total intestinal sarcomas, leiomyosarcomas with intestinal location are rare tumors (Brønden 2010). This can also be due to the fact that in comparison with human oncology, the gastrointestinal tumors are more rare, in a large scale study involving 10,270 cases being diagnosed only in 1.1% of the necropsies .…”

Frecuencia de Neoplasias en Caninos en Quito, Ecuador

“…Aunque existen diferencias, tanto entre las tipologías de cáncer reportadas como en la metodología de recolección e inclusión de los datos (Brønden et al, 2010), resulta útil comparar los resultados de centros de registro de neoplasias con los hallazgos de esta investigación. Los tumores cutáneos son los primeros por su incidencia en el perro (700 casos/100 000/año) Según el tipo histológico, los tumores cutáneos más frecuentes son los mastocitomas, los adenocarcinomas y los carcinomas de células escamosas (Dorn, 1976 El hecho de que la ciudad de Quito se encuentre sobre los 2800 msnm y reciba niveles extremos de radiación ultravioleta constituye un factor de riesgo permanente para el desarrollo de ciertas formas de cáncer de piel en animales y personas.…”
