“…The number of diagnosed tumours was found to increase gradually each year. As it would seem from the literature data, the prevalence of tumours in companion animals, mainly dogs, has been growing in recent years ( 8 ). Certainly, the present results confirm this, but factors must also be taken into account for a true interpretation of tumour incidence data, e.g .…”

“…In recent years, the incidence of neoplastic lesions in companion animals, especially dogs, has been steadily increasing (1,8,9,10,13,28). Skin tumours, which rank first among neoplastic lesions in dogs, are diagnosed most frequently (8). They are characterised by a vast array of histological types and constitute the most heterogeneous group of tumours.…”

Introduction The aim of the study was to compile data on the frequency and distribution of canine skin tumours and determine the risk of these being malignant as opposed to benign. This determination proceeded from tumour histogenesis and gave consideration to the dog’s breed, sex, age and the anatomical location of tumours. Material and Methods This retrospective five-year epidemiological study included 3,139 canine skin tumours collected in Poland. A univariable logistic regression analysis was performed to determine the odds ratios (ORs) with 95% confidence intervals (CIs). Results Microscopic analysis showed a significant predominance of benign tumours (65.02%) as well as mesenchymal and melanocytic tumours (59.57%). The most frequently diagnosed were mast cell tumours, accounting for 13.79% of all skin tumours, and other common tumour types were lipomas (6.40%), haemangiopericytomas (5.96%) and malignant melanomas (4.65%). The risk of malignant versus benign tumours was 1.212 times higher in the female than in the male dogs. A higher risk of development of malignant epithelial tumours was found in boxers (OR 4.091), German shepherds (OR 4.085) and flat-coated retrievers (OR 43.596). A higher risk of development of malignant mesenchymal tumours was found in golden retrievers (OR 4.693), boxers (OR 2.342), bulldogs (OR 3.469) and Maltese (OR 2.757). Conclusions The results may serve as a reference point for further studies of the complex biology of canine skin tumours.

“…The incidence of cancer is increasing globally in both humans and animals. This trend underscores a significant challenge in modern medical research, which is often hampered by the complex biology of cancer (Ciaputa et al 2022). Notably, the histological and genetic similarities between canine and human tumours position dogs as valuable models for studying cancer in humans (Schiffman and Breen 2015).…”

The aim of this study is to investigate the correlation between the incidence of spontaneous tumours of various origins and the localisation in dogs with sex, breed, and age factors. A total of 360 tumours with various localisation were studied pathomorphologically. Histopathologic data sets from 360 dog tissue samples were processed and statistically examined. A chi-square test of independence was conducted to examine the relationships among the various levels of the specified variables. Logistic regression models were employed for dichotomous outcomes to ascertain the influence of certain explanatory variables on the tumour types. Characteristic pathomorphological changes observed during examination of dogs with oncologic diseases were determined. The most common neoplasms were mammary tumours, accounting for 43% of the cases. The mammary gland tumours were most common in mongrel dogs (25%), with German Shepherds (17.3%), Poodles, Dachshunds, Central Asian Shepherds (6.7% each), and Rottweilers (5.7%) following. The highest frequency of these tumours appeared at 8 years of age, predominantly originating from the ductal epithelium, which represented 46.4% of all the malignant cases.

Neoplasms of the mammary glands are the most common tumours in female dogs, albeit rare cases in male dogs are reported as well. Canine mammary tumours (CMT) are a naturally occurring heterogeneous group of cancers with a high incidence rate of up to 25-50% among females. Despite many years of research, the aetiology and high incidence of these tumours are still poorly understood. There is a need to present epidemiological data on mammary tumour occurrence in different breeds of dogs in different countries to select prognostic risk factors and identify breeds with higher susceptibility to tumour development. The aim of this study was to describe histopathological findings for 92 animals, including 87 female and five male dogs, diagnosed with mammary gland tumours (MGTs) in Poland and to determine such epidemiological characteristics as age, breed and size as well as their relationship with tumour incidence and malignancy. Histopathological analyses showed that 82 (89.1%) of the 92 dogs had malignant tumours, seven dogs (7.6%) had benign tumours, and three dogs (3.3%) had non-neoplastic changes in the form of dysplasias. Thirty (33.7%) of the 89 dogs with mammary gland tumours had more than one neoplasia. The highest number of cases were epithelial tumours (79.8%), followed by mesenchymal (14.6%) and mixed (5.6%) tumours. The vast majority of malignant tumours were tubulopapillary carcinomas (33.7%), complex carcinomas (24.7%) and solid carcinomas (11.2%). It is worth noting a large variation in the degree of tumour malignancy among the tubulopapillary carcinoma cases. The present study showed a higher incidence of mammary gland tumours in female dogs aged 8-13 years. The vast majority of female cases were diagnosed at the age of 12 years. The average year of surgical intervention in the male dogs was 9 years. Among 25 breeds of dogs in which MGTs were noted, the highest number of affected animals were crossbreeds (30.3%), German Shepherds (23.6%) and English Cocker Spaniels (9.0%). The large size of the tumour (≥ 5 cm) was strongly associated with its malignancy.
