The medical records of 45 dogs with histopathologically confirmed osteosarcomas arising from flat or irregular bones were reviewed. Thirty-five percent of the dogs eventually developed metastases. Telangectatic tumors and tumors arising from the rib and scapula had the highest prevalence of metastases. Survival times were short, with an overall median survival time of 120 days. Anatomic site, body weight, and completeness of surgical excision were found to be prognostic factors. Dogs with mandibular osteosarcomas in this study had shorter survival times than those times recently reported. 21 Local recurrence was the most common cause of death or euthanasia in this population of dogs.
回顾了45只经组织病理学确诊为扁平骨或不规则骨骨肉瘤的犬的病历。35%的犬最终发生转移。血管扩张性肿瘤以及起源于肋骨和肩胛骨的肿瘤转移发生率最高。生存时间较短，总体中位生存时间为120天。发现解剖部位、体重和手术切除的完整性是预后因素。本研究中患有下颌骨肉瘤的犬的生存时间比最近报道的时间短。局部复发是这群犬死亡或安乐死的最常见原因。
