Neoplasia, Felinos, linfoblastosResumo
A leucemia é definida como uma neoplasia de células hematopoiéticas. Pode ser classificada em quadros agudos ou crônicos, sendo o vírus da FeLV intimamente ligado a causa de leucemias agudas. Em caráter retrospectivo, nove animais diagnosticados FeLV positivos, com a evidenciação de bicitopenia, associada ao predomínio de linfócitos (superior a 80%) foram selecionados para uma análise hematológica. Todos os animais apresentaram linfocitose acentuada (> 13.000 céls/μL) e em apenas dois gatos foram encontrados linfoblastos. O protocolo quimioterápico Wisconsin-Madison modificado foi realizado em quatro gatos, mas somente o gato 7 sobreviveu e obteve melhora do quadro clínico. Os nove gatos avaliados neste trabalho apresentaram características compatíveis com um quadro leucêmico agudo, tendo uma sobrevida de 16 dias, o que indica ser uma enfermidade de curso rápido e prognóstico ruim, dificultando a realização de exames mais complexos para um diagnóstico definitivo.
