Treating metastatic osteosarcoma (OS) remains a challenge in oncology. Current treatment strategies target the primary tumour rather than metastases and have a limited efficacy in the treatment of metastatic disease. Metastatic cells have specific features that render them less sensitive to therapy and targeting these features might enhance the efficacy of current treatment. A detailed study of the biological characteristics and behaviour of metastatic OS cells may provide a rational basis for innovative treatment strategies. The aim of this review is to give an overview of the biological changes in metastatic OS cells and the preclinical and clinical efforts targeting the different steps in OS metastases and how these contribute to designing a metastasis directed treatment for OS.
治疗转移性骨肉瘤(OS)仍然是肿瘤学的一个挑战。目前的治疗策略针对的是原发肿瘤,而不是转移灶,并且在转移性疾病的治疗中疗效有限。转移性细胞具有使其对治疗的敏感性降低的特定特征,针对这些特征可能会提高当前治疗的疗效。对转移性 OS 细胞的生物学特征和行为进行详细研究,可为创新治疗策略提供合理依据。本文综述的目的在于概述转移性 OS 细胞的生物学变化,以及针对 OS 转移不同步骤的临床前和临床努力,以及这些努力如何有助于设计针对 OS 的转移性治疗。
