Abstract
Nasal tumors are one of the most common tumors in aged golden retrievers. Adenocarcinomas or carcinomas are diagnosed in the majority of nasal tumors. Radiation therapy is the first option to decrease the size of tumor, and oral or intravenous chemotherapy is administered depending on the prognosis. Therefore, it is important to select the most appropriate drug for chemotherapy considering the price and the presence of concurrent disease. Anticancer drugs include first-generation chemotherapies, second-generation targeted anticancer drugs, and third-generation immunotherapy drugs. Considering their price and effectiveness, first- or second-generation anticancer drugs are mainly used.We report a first case in which a retriever with a nasal tumor was successfully treated and managed using a metronomic combination of chlorambucil (4mg/day, SID) and prednisolone (10mg/day) orally for 9 months at a general practice. A 35 kg spayed female golden retriever aged 8 years and 8 months visited the Bundang New York Animal Hospital in July 2023. A protocol of 4 weeks of chemotherapy followed by 1 week of rest was repeated, and the nasal exudate was significantly reduced. The size of the nasal tumor was monitored using Computed Tomography (CT) imaging at a referral hospital, and the images were taken in the following order: 1. before radiation therapy at the referral hospital and before chemotherapy; 2. after radiation therapy and before chemotherapy; and 3. after radiation therapy and after chemotherapy. Since the first occurrence of epistaxis, 12 months have passed (as of July 24). The nasal exudate is barely visible, and the retriever’s vital signs and weight remain stable. The size of the nasal tumor significantly decreased after 9 months of chemotherapy without moderate side effects. This study demonstrates that a prednisolone/chlorambucil metronomic combination can be an alternative to kinase inhibitor drugs as it is the cheapest and most effective way to manage tumors along with conventional radiation therapy.
