Resumo
Background: Canine transmissible venereal tumor (TVT) is a tumor of round cells. Vincristine sulfate is the most effective for TVT. Alternatively, hemotherapy is an alternative therapy that consists of the administration of autologous blood and the positive effects are associated with an immunomodulatory effect. Since chemotherapy has some collateral effects, it is necessary to study another treatment with minimal side effects. In this context, this report case aimed to describe the use of autohemotherapy associated with vincristine sulfate for treating a transmissible venereal tumor in the vulvar mucosa of 7 adult bitches, being the first case report in Mozambique, Africa. Case: Seven adult bitches, median size, were referred to the School Veterinary Hospital, School of Veterinary, Eduardo Mondlane University, Maputo, Mozambique, Africa, with a diagnosis of TVT in the vulvar mucosa. All bitches were treated weekly with autohemotherapy and vincristine sulfate for 21 days. The parameters assessed included clinical and TVT macroscopic examination, complete blood count, serum biochemical examination and urinalysis, and were evaluated 60-min before each treatment. No clinical side effects were identified during the treatments. Color, appearance and tumor size were changed during the treatment period, and all bitches showed complete remission of the tumor 21 days after the beginning of treatment or after the third therapeutic session. The values of the complete blood count, serum biochemical and urinalysis did not demonstrate significant variations throughout the evaluated time-points. The TVT cytopathological classification was lymphocytic (42.9 %), plasmacytic (28.6 %) and lymphoplasmacytic (28.6 %). Discussion: The aims of this report were to describe the combination of autohemotherapy and vincristine sulfate for treating the transmissible venereal tumor located in the vulvar mucosa of adult bitches, through clinical and laboratory evaluation, and was not...
