Uso da radioterapia no tumor venéreo transmissível em cães

Since the discovery of x rays, the use of radiation in oncology has advanced remarkably. In Brazil, radiation therapy in animals is limited to some isolated studies in public universities and the procedures performed is still precarious because radiation equipments are expensive and there is still a lack of skilled professionals. The transmissible venereal tumor (TVT) is a contagious neoplasm of spontaneous occurrence, commonly treated with vincristine. This paper describes the positive experience of radiotherapy as an isolated option or as an combined treatment with vincristine in three cases of TVT. It was observed that radiotherapy may be used in routine clinical chemotherapy alone or combined with chemotherapy since suitable sources of radiation are provided.
