Gastric neoplasms in the dog: a report of 20 cases.
Twenty dogs with gastric tumors were admitted to the University of Minnesota Veterinary Hospital and Diagnostic Laboratory from 1951 to 1974. The tumors included 14 carcinomas, 3 lymphosarcomas, 2 leiomyomas, and 1 leiomyosarcoma. The carcinomas were categorized morphologically as carcinoma (5), adenocarcinoma (2), scirrhous carcinoma (5), and scirrhous adenocarcinoma (2). Most of the tumors were located in the body and pylorus. Ulceration occurred in 11 dogs, with 2 ulcers penetrating and resulting in peritonitis. Metastasis occurred in 4 of the dogs. The mean age of the dogs was 9.7 years. The male-to-female ratio was 12 to 8. There was no significant breed predominance. The mean duration of illness was 2.14 months. Radiographic features were consistent with gastric neoplasia in 2 of 6 dogs radiographed.
