This study aimed to determine the most prevalent mammary tumors in cats and associate them to some prognostic factors. The files from the Laboratório de Patologia Veterinária (LPV) of the Universidade Federal de Santa Maria (UFSM) were reviewed, and 1.427 feline biopsies and autopsy protocols between the years 2000 and 2011 were found. Based on the information retrieved from the files, a relationship was established among the tumors and some prognostic factors such as sex, age, breed, reproductive status, use of contraceptives, number and location of affected glands, ulcers, size of the neoplasm, distant metastases, and affected lymph nodes. Thus, it was observed that mammary cancer is the second most prevalent diagnosis, following skin tumors. All cats with mammary tumors were female, being the elderly and mixed breed the most affected. Malignant neoplasms were the most frequently diagnosed, followed by non-neoplastic tumors, and benign neoplasms. Smaller tumors were mostly carcinomas. Ulcerations were present not only in malignant neoplasms but also in non-neoplastic changes. Distant metastases were found mainly to the lungs and skin. |
