Treatment of solid tumors in dogs using veterinary high-intensity focused ultrasound: A retrospective clinical study

초록

High-intensity focused ultrasound (HIFU) is a cancer treatment tool that focuses ultrasound energy on tumor tissues, which initiates necrosis via heat and mechanical effects. The efficacy of veterinary HIFU (vHIFU) was evaluated for the treatment of solid tumors in dogs. Data from 11 client-owned dogs with various solid tumors treated by vHIFU between 2013 and 2017 were retrospectively evaluated. Ten of the 11 dogs were followed up; clinical signs were alleviated in five. Four dogs exhibited a decrease in tumor size, and bleeding stopped in all four dogs with hemorrhagic tumors. Side effects included hyperthermia or erythema on the application site, enteritis, and skin ulcerations. These results suggest that vHIFU could be used as an alternative cancer treatment for dogs with solid tumors. (C) 2018 Published by Elsevier Ltd.
