Clinical outcomes of 30 cases (1997-2004) of canine gastrointestinal lymphoma

In 30 cases of canine gastrointestinal lymphoma, each case was localized to the stomach, small intestine, large intestine, or two or more sites. Treatments consisted of surgery alone (n=4), surgery with chemotherapy (n=8), chemotherapy alone (n=15), or supportive care (n=3). Four dogs died, 24 were euthanized, and two are currently alive. Median survival time for all cases was 13 days. In both surviving dogs, the site of lymphoma was the large intestine. Canine gastrointestinal lymphoma is a severe disease that warrants a poor to grave prognosis. However, cases of colorectal origin may have longer survival times.
