Osteosarcoma is a highly malignant tumor with unsatisfactory therapeutic outcomes achieved by chemotherapy, radiotherapy, and surgery. As an emerging oncological treatment, immunotherapy has shown potential in the clinical management of many tumors but has a poor response rate in osteosarcoma. The immunosuppressive microenvironment in osteosarcoma is the main reason for the ineffectiveness of immunotherapy, in which the low immune response rate of immune effector cells and the high activation of immunosuppressive cells contribute to this outcome. Therefore, modulating the function of the immune microenvironment in osteosarcoma is expected to remodel the immunosuppressive microenvironment of osteosarcoma and enhance the efficacy of immunotherapy. This article reviews the role of immune cells in the progression of osteosarcoma, describes the corresponding regulatory tools for the characteristics of different cells to enhance the efficacy of osteosarcoma immunotherapy, and concludes the prospects and future challenges of osteosarcoma immunotherapy.
骨肉瘤是一种高度恶性的肿瘤,化疗、放疗和手术治疗效果均不理想。作为一种新兴的肿瘤治疗方法,免疫疗法在许多肿瘤的临床治疗中显示出潜力,但在骨肉瘤中的反应率较低。骨肉瘤中的免疫抑制微环境是免疫疗法无效的主要原因,其中免疫效应细胞的低免疫反应率和免疫抑制细胞的高激活导致了这一结果。因此,调节骨肉瘤免疫微环境的功能有望重塑骨肉瘤的免疫抑制微环境并提高免疫疗法的疗效。本文综述了免疫细胞在骨肉瘤进展中的作用,描述了针对不同细胞特征提高骨肉瘤免疫治疗疗效的相应调控手段,并总结了骨肉瘤免疫治疗的前景和未来挑战。
