Resumo
Background: Mammary tumors are extremely common in cats and have high metastatic rates with poor prognosis. The main objective of the present study was to evaluate the disease free interval and survival in cats undergoing radical mastectomy as sole therapy. Materials, Methods & Results: Twenty cats with mammary tumors and no evidence of distant metastasis were studied. General health and concomitant diseases were assessed by clinical and hematological examination. Thoracic radiographs and abdominal ultrasonography were performed to evaluate thoracic and abdominal metastases. All cats underwent chain mastectomy, which was unilateral when tumor was present in one mammary chain, and bilateral in steps if tumors were present in both mammary chains. Intact cats were spayed. An elliptical incision was made around the mammary chain with a three centimeter margin around tumor. Regional lymph node was removed. Mean age was ten years, and 14 cats were mixed breed, three were Persian and two were Siamese. Fifteen cats were spayed at tumor diagnosis, but only three had been spayed before one year old. The inguinal mammary glands were the most affected, followed by abdominal and thoracic glands. Histopathology diagnosed well-differentiated adenocarcinoma in eight cases, moderately differentiated adenocarcinoma in nine cases, poorly differentiated adenocarcinoma in two cases [...](AU)
