Abstract: | Eight cats with locally advanced, oral squamous cell carcinoma (SCC) were treated with a combination of gemcitabine and palliative radiotherapy. Low-dose gemcitabine was administered twice weekly (25 mg/m2) in conjunction with megavoltage radiation in 6 Gray (Gy) fractions for a total dose of 36 Gy. Responses included two complete and four partial responses, and two cats had no response to therapy. Median duration of remission was 42.5 days (range, 11 to 85 days). Median survival time was 111.5 days (range, 11 to 234 days). This data suggests that a combination of low-dose gemcitabine and palliative radiation therapy may be tolerable for cats with oral SCC and may cause a therapeutic benefit. |
