Animals with tumors are recently treated by surgery, radiotherapy and chemotherapy, similarly to human medicine. To select optimal treatment for each tumor, many studies have been reported in veterinary medicine. Response rate and survival rate are generally used to evaluate each treatment. Prospective cohort study and experimental study, which have comparable internal control and few biases, are ideal, but take much time and cost. Realistically, most clinical studies are categorized to case report, case series study and retrospective study with external control. Our veterinary clinicians should create an environment to design ideal clinical study with statisticians.
