Plain-English summary
Two related male Persian cats, both 12.5 years old and neutered, were found to have stomach cancer (gastric adenocarcinoma) along with chronic inflammation of the stomach lining (chronic gastritis). They showed symptoms like vomiting, throwing up blood, passing dark stools, and losing weight, with the first cat starting to show signs about two months before the second. One cat had some unusual parasites and bacteria found in its stomach, while the other did not have any identifiable causes after treatment for the parasites. This case suggests that their cancer might be linked to shared genetic or environmental factors, but the exact reasons are still unclear. Unfortunately, both cats were diagnosed with cancer, which is a serious condition.
Abstract
Two 12.5-year-old castrated male Persian cats from the same household, whose dams were littermates, presented simultaneously with gastric adenocarcinoma associated with proliferative and fibrosing gastritis. Intralesional adult Ollulanus tricuspis nematodes and rare surface-associated spiral-shaped bacteria were identified in one cat. No etiologic agents were identified in tissues from the second cat; however, gastric mucosa was examined following anthelmintic treatment. Clinical signs in each cat had commenced 2 months apart and included vomiting, hematemesis, intermittent melena, and weight loss. This is the first report of gastric adenocarcinoma occurring in housemate cats or cats of common descent. Carcinogenesis may have been influenced by shared undetermined genetic and environmental factors, possibly including Ollulanus tricuspis, spiral-shaped bacteria, or other etiologies for chronic gastritis that remain unidentified.
