| Abstract: | A 4.5-year-old, neutered male ferret with a history of recurrent adenocarcinoma in the preputial region was given 2 radiation treatment courses designed to control the rapidly growing neoplasm. The tumor regressed completely after the first 3.5-week course of therapy. The ferret remained clinically disease-free for 4 months, at which time small masses were noticed in the inguinal area and the original tumor site. A second course of therapy was administered, which again resulted in complete clinical regression of the neoplasm. However, the duration of remission was brief. Local recurrence and abdominal metastasis were observed within 2 months of the completion of therapy. |
