The malignant transformation of mesenchymal cells within the bone leads to the development of osteosarcoma (OS), but the genetic underpinnings of these events are not understood. From a clinical perspective, primary tumour management can be achieved successfully in most patients. However, the development of metastasis to the lungs represents the most common cause of death in OS patients. A clearer understanding of metastasis biology is required to improve cancer mortality and improve outcomes. Modelling the genetics, biology and therapy of OS can be accomplished through research involving a number of species. Most notable is the naturally occurring form of OS that develops in dogs. Through a cross-species and comparative approach important questions can be asked within specific and suitable models to advance our understanding of this disease and its common metastatic outcome. A comparative perspective on the problem of OS metastasis that utilizes a cross-species approach may offer unique opportunities to assist in this prioritization and generate new hypotheses related to this important clinical problem.
骨内间充质细胞的恶性转化会导致骨肉瘤(OS)的发生,但这些事件的遗传学基础尚不清楚。从临床角度来看,大多数患者的原发性肿瘤都能得到成功治疗。然而,肺转移的发生是骨肉瘤患者最常见的死亡原因。需要更清楚地了解转移生物学,以降低癌症死亡率并改善治疗效果。通过涉及多个物种的研究可以实现对骨肉瘤的遗传学、生物学和治疗方法的建模。最值得注意的是狗自然发生的骨肉瘤形式。通过跨物种和比较的方法,可以在特定且合适的模型中提出重要问题,以加深我们对这种疾病及其常见转移结果的理解。利用跨物种方法对骨肉瘤转移问题进行比较研究,可能会提供独特的机会来协助确定研究重点,并产生与这一重要临床问题相关的新假设。
