Fourteen dogs (11 females, three males) with extraskeletal osteosarcomas (EsOSAs) were identified. The median age was 11.5 years. The median body weight was 18 kg. The primary sites of the EsOSAs were the spleen (n=6), mammary gland (n=3), lung (n=2), and one each in the skin, axilla, and mesenteric root. The overall median survival time was 74 days. The only factor which was found to be prognostic for survival was the use of chemotherapy (p of 0.02). Cases which did not have chemotherapy were 3.62 times as likely to die a tumor-related death than cases which had chemotherapy.
共鉴定出14只患有骨外骨肉瘤（EsOSA）的犬（11只雌性，3只雄性）。中位年龄为11.5岁。中位体重为18千克。EsOSA的原发部位为脾脏（n = 6）、乳腺（n = 3）、肺（n = 2），皮肤、腋窝和肠系膜根部各1例。总体中位生存时间为74天。唯一被发现对生存有预后意义的因素是化疗的使用（p = 0.02）。未接受化疗的病例发生肿瘤相关死亡的可能性是接受化疗病例的3.62倍。
