摘要:

骨肉瘤是青少年最常见的原发性恶性骨肿瘤,侵袭性强、预后不佳,尽管诊疗手段不断丰富,患者生存率仍未见显著提升,因此深入解析其发生发展机制尤为迫切。上皮间质转化(EMT)是驱动其恶性进展的核心生物学过程,通过促进肿瘤细胞迁移、侵袭、增殖,诱导肿瘤干细胞特性及化疗抵抗,进而影响患者预后。然而,EMT的动态可逆性、肿瘤内异质性以及现有体外/体内模型的局限性,制约了其临床转化应用,深入解析其调控机制,通过靶向抑制EMT在骨肉瘤中的表观遗传、肿瘤微环境及关键信号通路等方式,有望突破骨肉瘤治疗瓶颈,为克服肿瘤转移与耐药提供新方向,最终改善患者预后。

Abstract:

Osteosarcoma is the most common primary malignant bone tumor in adolescents, characterized by strong invasiveness and poor prognosis. Despite continuous advances in diagnostic and therapeutic methods, patient survival rates have not shown significant improvement, making it particularly urgent to deeply elucidate the mechanisms underlying its occurrence and progression. Epithelial-mesenchymal transition (EMT) is a core biological process driving the malignant progression of osteosarcoma, influencing patient prognosis by promoting tumor cell migration, invasion, and proliferation, inducing cancer stem cell characteristics and chemotherapy resistance. However, the dynamic reversibility of EMT, the intratumoral heterogeneity, and the limitations of current in vitro/in vivo models constrain its clinical translation and application. Nevertheless, in-depth analysis of its regulatory mechanisms and targeted inhibition of EMT through epigenetic modulation, tumor microenvironment intervention, and key signaling pathway blockade in osteosarcoma hold promise for breaking through therapeutic bottlenecks, providing new directions for overcoming tumor metastasis and drug resistance, and ultimately improving patient prognosis.
