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.
本研究旨在调查不同起源的自发性肿瘤发病率与犬类性别、品种和年龄因素的局部定位之间的相关性。对总共360例具有不同局部定位的肿瘤进行了病理形态学研究。对来自360份犬组织样本的组织病理学数据集进行了处理和统计分析。进行了独立性卡方检验，以检验指定变量不同水平之间的关系。采用逻辑回归模型分析二分结果，以确定某些解释变量对肿瘤类型的影响。确定了在患有肿瘤疾病的犬类检查过程中观察到的特征性病理形态学变化。最常见的肿瘤是乳腺肿瘤，占病例的43%。乳腺肿瘤在杂种犬中最常见（25%），其次是德国牧羊犬（17.3%）、贵宾犬、腊肠犬、中亚牧羊犬（各占6.7%）和罗威纳犬（5.7%）。这些肿瘤的最高发病频率出现在8岁，主要起源于导管上皮，占所有恶性病例的46.4%。
