Resumo
As neoplasias mamárias em cadelas representam importante parcela das neoplasias em cães, merecendo atenção dos pesquisadores quanto ao diagnóstico, tratamento e prognóstico. No presente trabalho, 23 cadelas de várias raças ou cruzamentos, com idades entre 8 e 11 anos portadoras de neoplasia mamária foram estudadas. Doze eram multíparas, 6 primíparas e 5 nulíparas. Todas eram da região de Jaboticabal, SP, atendidas no Hospital Veterinário da FCAVJ-UNESP. Os animais foram avaliados clínica e radiolagicamente e submetidos à punção aspirativa da massa anormal de tecido, com agulha fina. Dessa mesma massa foi também retirado, cirurgicamente, um fragmento para exame histopatológico. A maior incidência foi de carcinoma (52,17%), seguidos por tumores mistos (17,39%). Os tratamentos cirúrgicos empregados nos 23 animais foram: mastectomia regional ou mastectomia em bloco, com remoção de linfonodos. Quinze cadelas foram tratadas com doxorubicina, na dose de 20mg/m² e ciclofosfamida, na dose de 100mg/m², aos 7, 9 e 11 dias após o ato cirúrgico. Todos os animais tiveram evolução favorável e, 12 meses após a cirurgia, 18 deles foram reavaliados, não constatando nenhuma recidiva ou surgimento de metástase.
Mammary gland tumors in female dogs are among the most important neoplasia in dogs, deserving special attention regarding its diagnosis, treatment and prognosis. In this study, 23 biches of different breeds, from 8 to 11 years of age, with mammary tumors were evaluated. of the se, 12 were multiparous, 6 primiparous and 5 were nuliparous. All dogs came from the region of Jaboticabal, SP and were referred to the Veterinary Teaching Hospital of the FCAVJ-UNESP. The animals were evaluated clinically and radiographically and the mammary mass submitted to an aspirative needle. A fragment of the tumor was also removed surgically for histopathological examination. Most tumors were classified as carcinomas (52.17°/o), followed in number by mixed tumors (17.39%). Treatment included mamectomy, partial mastectomy or en bloc mastectomy with removal of the lymphnodes. Most dogs also received Doxorubicin (20mg/m²) and Cyclokphosphamide (100mg/m²) at, 7, 9 and 11 days post-operative. All dogs recovered uneventfully and at one year post-operative. Twelve dogs were reevaluated an considered to be free of recurrence of metastasis.
