Simple Summary: This study aimed to evaluate the outcomes and prognostic factors for multicentric lymphoma in 38 small breed dogs (weighing under 15 kg) treated with combination chemotherapy with vincristine, cyclophosphamide, doxorubicin, and prednisolone between January 2014 and May 2020. Significant factors for longer mean survival time in the complete remission group included being under 10 years old, no cardiovascular heart disease, and no prior hospitalization due to chemotherapy side effects. These results will help confirm the clinical characteristics and outcomes in small breed dogs with lymphoma and provide insights into the most effective treatments and prognosis for these animals. Lymphoma is one of the most common malignant tumors in dogs. Combination chemotherapy with vincristine, cyclophosphamide, doxorubicin, and prednisolone (CHOP) is the most effective treatment for multicentric lymphoma. Previous studies have evaluated the response of large dogs to CHOP treatment and identified prognostic factors; however, studies on small dogs are lacking. In this study, we investigated the outcomes and prognostic factors for small dogs with multicentric lymphoma treated with CHOP. The responses of patients to CHOP treatment were assessed, and 54.3% were evaluated as being in complete remission (CR), 31.4% in partial remission (PR), and 14.3% in no remission (NR). The overall response rate was 85.7%. The median survival times for CR, PR, and NR patients were 683 days (85–1496 days), 241 days (15–777 days), and 119 days (61–308 days), respectively. Among the CR patients, survival was longer under the following conditions: age under 10 years (p = 0.011), no cardiovascular heart disease (p = 0.046), and no history of hospitalization due to side effects from chemotherapy (p = 0.002). These results might help clinicians build treatment plans for multicentric lymphoma in small breed dogs. [ABSTRACT FROM AUTHOR] more...
