Oral neoplasia has been reported to account for 6-7% of all canine cancer and 3% of all feline cancers. To the authors' knowledge the last epidemiologic analysis of general oral cancer in dogs and cats was published in 1976.
The goal of this study was to report contemporary demographic information regarding oral tumors in dogs and cats.
Information was collected from cats or dogs diagnosed with oral neoplasia from the Veterinary Medical Data Base. Medical records representing cases that presented to one of 26 veterinary teaching hospitals from January 1, 1996 through December 31, 2017 were included.
A total of 1,810 dogs and 443 cats were identified. A total of 962 cases (53.6%) of canine oral tumors were classified as malignant and 455 cases as benign (25.4%). The majority of feline oral tumors were classified as malignant (257 cases, 58.1%) and only a few benign (11 cases, 2.5%). The incidence of oral tumors was calculated to be 4.9 per 1,000 dogs (0.5%) and 4.9 per 1,000 cats (0.5%).
This incidence of oral tumors is considerably higher than previously reported in both dogs and cats. These results provide valuable information for generation of hypotheses for future investigations of breed-based and pathology-based oral neoplastic studies.
据报道，口腔肿瘤占所有犬类癌症的6 - 7%，占所有猫类癌症的3%。据作者所知，上一次关于犬猫口腔癌的流行病学分析发表于1976年。
本研究的目的是报告有关犬猫口腔肿瘤的当代人口统计学信息。
从兽医医学数据库中收集被诊断患有口腔肿瘤的猫或犬的信息。纳入了1996年1月1日至2017年12月31日期间到26家兽医教学医院之一就诊的病例的医疗记录。
共识别出1810只犬和443只猫。犬口腔肿瘤中共有962例（53.6%）被分类为恶性，455例为良性（25.4%）。大多数猫口腔肿瘤被分类为恶性（257例，58.1%），只有少数为良性（11例，2.5%）。经计算，口腔肿瘤的发病率为每1000只犬4.9例（0.5%），每1000只猫4.9例（0.5%）。
口腔肿瘤的这种发病率在犬和猫中均明显高于先前报道。这些结果为基于品种和病理学的口腔肿瘤研究的未来调查生成假设提供了有价值的信息。
