骨肉瘤肺转移的作用机制及其临床治疗策略
Mechanisms and clinical therapeutic strategies for pulmonary metastasis in osteosarcoma
摘要
Abstract
Osteosarcoma,the most common primary malignant bone tumor,is characterized by aggressive local invasion and a high propensity for distant metastasis,particularly to the lungs.Pulmonary metastasis is a critical determinant of poor prognosis,with 5-year survival rates plummeting below 20%in metastatic cases.Despite advances in primary tumor resection,the molecular and microenvironmental mechanisms driving post-surgical pulmonary recurrence and metastasis remain insufficiently elucidated.This review synthesizes recent advances in understanding the multifactorial pathogenesis of osteosarcoma pulmonary metastasis,emphasizing the roles of surgical trauma-induced inflammatory cascades,immune evasion(PD-1/PD-L1 axis dysregulation),angiogenic reprogramming,oncogenic drivers(e.g.,MYLK overexpression),and pre-metastatic niche formation in promoting tumor cell migration,invasion,and pulmonary colonization.Furthermore,we critically evaluate current clinical strategies,including immune checkpoint inhibitors,tyrosine kinase inhibitors,and metastasis-targeted therapies,while highlighting emerging approaches such as microenvironment modulation and epigenetic therapeutics.By integrating mechanistic insights with translational evidence,this review proposes a framework for developing combinatorial therapies to suppress metastatic progression and improve patient outcomes.关键词
