Abstract

Tumors (neoplasia) is a widespread pathology among domestic animals that live in close proximity to humans. They are affected by the same ecological, technogenic, fodder, climatic and other factors. Therefore, any information on the incidence, etiology, peculiar signs, the course of neoplasias in small domestic animals is relevant for comparative oncology. 73 cases of neoplasia in small animals living together with their owners in conditions of Dnipro city (Ukraine) were studied. The species and age predisposition, organ localization, structure of neoplasms in animals was determined. Statistical, clinical and pathohistological methods of research were used. Verification of neoplasia was carried out by microscopy of histological sections stained with hematoxylin and eosin. It was established that among animals with neoplasia there were dogs, cats, ferrets, guinea pigs, rats, and rabbits. Neoplasms were more frequently observed in dogs (61.7%), while in cats they were almost half the number found in dogs (30.1%), among other animals, the incidence of neoplasia did not exceed 8.2%. In dogs, mostly benign neoplasms were discovered in skin and soft tissues, histogenesis from the connective tissue by the histiocytoma (48.5%). In cats, oral cavity was the place of common localization of neoplasias (45.5%), the structure is predominated by benign tumors (53.4%) of connective tissue (46.7%), including fibromas (26.6%). Tumors of the mammary gland both in dogs and cats take the second place by localization factor. Among tumors of the mammary gland, malignant neoplasms are diagnosed more frequently: 85.7% in dogs and 90.0% in cats. In cats, infiltrating forms of cancer prevail, and in dogs the percentage of infiltrating and non-infiltrating forms of breast cancer is the same. A clear dependence of neoplasm formations on the age of animals in tested group was not established.
