Plain-English summary
A group of 93 dogs with canine transmissible venereal tumor (CTVT) received vincristine chemotherapy to treat their tumors. Their quality of life was monitored using a special scoring system adapted for dogs, which helped track any side effects during treatment. The study found that dogs with lower quality of life scores and reduced body weight were more likely to face serious outcomes, including death. Overall, the chemotherapy was effective in shrinking the tumors, and the quality of life score proved to be a useful tool for assessing the dogs' health during treatment.

Abstract
The clinical utility of a life quality score during vincristine chemotherapy of dogs with canine transmissible venereal tumor (CTVT) was investigated using 93 tumor-bearing dogs in this prospective study. At diagnosis, clinical data and the performance status were evaluated according to a modified Karnofsky score (CKS) adapted for dogs. The animals were treated with vincristine sulphate (0.025mg/kg) at weekly intervals until the tumor had macroscopically disappeared. The time until the first adverse event and death were recorded. In a pilot study, CKS revealed a high inter-observer concordance (kappa=0.735; weighted kappa=0.835). CKS permitted a detailed monitoring of adverse effects during therapy. Cox regressions showed that low performance score and reduced body weight were independent predictive factors for death during chemotherapy. The modified Karnofsky performance score is a simple and reproducible clinical instrument, able to estimate patient outcome after treatment of CTVT.<br>Investigou-se a utilidade clínica de uma escala de qualidade de vida durante o tratamento quimioterápico de cães com tumor venéreo transmissível canino (TVTC) em 93 animais com TVTC que compuseram este estudo prospectivo. Ao diagnóstico, foram avaliados os dados clínicos e o escore de qualidade de vida adaptado para cães (CKS). Os animais foram tratados com sulfato de vincristina (0.025mg/kg) semanalmente até o desaparecimento macroscópico do tumor. Foram anotados o tempo até o aparecimento do primeiro evento adverso e a morte. Em estudo piloto do CKS, alta concordância entre os observadores foi demonstrada (kappa = 0.735; weighted kappa = 0.835). O CKS permitiu um detalhado monitoramento dos eventos adversos durante a terapia. A regressão Cox multivariada demonstrou que o baixo escore de qualidade de vida e o reduzido peso corporal foram fatores preditivos independentes para o óbito durante a quimioterapia. A escala modificada de Karnofsky é um instrumento clínico simples e reproduzível, hábil em estimar os efeitos do tratamento no TVTC.
