Evaluation of cat tumors in Samsun between 2004-2022

Abstract

This study investigated the incidence of various tumors detected in 169 cat tissue and organ samples brought to the Samsun Ondokuz Mayis University, Veterinary Faculty, Department of Pathology between 2004–2022. Of the 169 specimens, five were acquired from necropsy and 164 were biopsy samples. Various tumors were evaluated retrospectively according to localization, sex, breed, and tumor origin. Tumors were common in mixed breeds (n = 96, 56.8%). Age of tumor incidence was examined; cats between 6 and 9 years of age most frequently had tumors (n = 45, 26.6%) in both sexes. In terms of tumor origin, 79 (47.0%) were mesenchymal, 83 (49.4%) were epithelial, and seven (4.2%) were of mixed components, i.e., mesenchymal and epithelial. In total, 147 (87%) tumors were classified as malignant and 22 (13%) tumors were classified as benign. Regardless of sex, the most commonly observed tumors were skin and subcutis tumors (n = 56, 32.1%). In conclusion, tumor incidence in Samsun was determined by retrospectively evaluating tumors in cats according to location, breed, sex, age range, and origin and comparing these with the literature.
