New Radiation Therapy for Oral Cancer

Feline oral squamous cell carcinomas (OSCCs) account for about 10 percent of all feline tumors and are the most common oral tumors in cats. They interfere with eating and drinking and are so painful that most cats with these devastating tumors are euthanized. Because treatment with surgery, chemotherapy or radiation therapy usually fails, most owners and veterinarians don’t even attempt treatment. A new tool called stereotactic radiation therapy is equipped with an X-ray machine and special computers to provide more targeted treatment, allowing for higher doses of radiation over a shorter time with fewer side effects. This study will treat cats with OSCC with stereotactic radiation therapy. Findings will advance the understanding of these difficult tumors and improve treatment and the quality of life for affected cats.
