A retrospective research of the spread of viral leukemia and immunodeficiency in cats with oncological pathology, taking into account gender and age

The data on the prevalence of viral leukemia and immunodeficiency in cats with oncological diseases are presented. From September 2018 to November 2024, 296 cats, 95 males and 201 females, aged from 7 months to 19 years, were admitted for oncological admission. Virus transmission was detected in 34 cases of all patients with oncological pathology, which amounted to 11,48 %. Leukemia was registered in 31 (91,17 %) cats, immunodeficiency – 2 (5,88 %), viruses of two nosologies simultaneously in 1 (2,94 %) animal. The carrier of viral leukemia was determined in neoplasia of the hematopoietic system (35,71 %), breast tumors (5,66 %) and soft tissues (7,14 %). At the same time, leukemia and immunodeficiency viruses were diagnosed in a single case in a young cat with lymphoma. The immunodeficiency virus was registered in two animals with squamous cell carcinoma of the oral cavity, which accounted for 10 % of all formations of this anatomical localization. The incidence of chronic viral infections among cats of both sexes did not differ significantly: males – 47 %, females – 53 %. The clinical manifestation of oncological pathology in virus-carrying cats was associated with a younger age – 5 years 7 months ± 0,43 (min. 7 months – max. 17 years).
