Abstract

A statistical analysis of the prevalence of tumor pathology of dogs in the city of Dnipro. 418 cases of registered oncological diseases of dogs were analyzed. It was found that malignant neoplasms are 1.5 times more common than benign. The most common tumors in dogs are tumors of the breast (35,9%), skin (22,0%), genitals (15,3%) and lymphoma(8,4%). Malignant neoplasms of the breast are registered 3.6 times more often than benign and surpass them in morphological varieties. Fibroadenomas and infiltrating and non-infiltrating carcinomas were mainly registered. Approximately the same number of cases of infiltrating and non-infiltrating cancers were noted. Benign skin tumors are more common than malignant. Mastocytosis, melanoma, and squamous and basal cell carcinomas of the skin and sebaceomas were the most commonly reported. In terms of morphological varieties, benign skin neoplasms are superior to malignant ones. Lipomas and papillomas are very common. Genital neoplasms of females and males are also common. Almost half of male genital tumors were malignant seminomas. Among benign neoplasms, serteliomas and leydigomas were more common. In females, the most common are uterine leiomyoma, vaginal fibroma and ovarian carcinoma. Lymphomas (8.4%) are also widespread in dogs in the metropolis. The average age of registration of these neoplasms was 7.5 years. Benign tumors in the oral cavity of dogs were twice as common as malignant, of which fibrosarcomas, squamous keratinized and non-keratinized carcinomas, and salivary gland adenocarcinomas were reported. In females, oral neoplasia occurred 3.2 times more often than in males. Only malignant venereal sarcomas and carcinomas were found in the nasal cavity of dogs. Sexual and pedigree predisposition was not observed here. Among neoplasms of muscles and bones there was only a malignant oncological pathology. Rhabdomyosarcomas, fibrosarcomas, myxoid liposarcomas and other soft tissue sarcomas were diagnosed in different parts of the dog’s body. Bone neoplasms are represented by osteosarcomas. Dogs of large breeds were most often affected and in most cases the hind limbs were affected. The predominant histological subtype was osteoblastic osteosarcoma.
