摘 要
肿瘤免疫治疗作为新兴的癌症治疗策略，通过激活机体自身免疫系统来识别和杀伤肿瘤细胞，已成为继手术、放疗和化疗之后的重要治疗手段。本研究旨在深入探讨肿瘤免疫治疗中药物的作用机制与疗效评估，聚焦于免疫检查点抑制剂、细胞因子疗法及过继性细胞疗法等代表性药物类型。基于此，采用文献综述与临床数据分析相结合的方法，系统梳理了相关药物从实验室研发到临床应用的全过程。通过对大量临床试验数据的分析发现，免疫检查点抑制剂能够阻断肿瘤微环境中存在的免疫抑制信号通路，恢复T细胞对肿瘤细胞的识别能力；细胞因子疗法可调节体内免疫细胞活性，增强抗肿瘤免疫反应；过继性细胞疗法则为患者提供经过体外修饰后具有更强特异性杀伤力的免疫细胞。研究结果表明，上述药物在多种实体瘤和血液系统恶性肿瘤中展现出显著疗效，部分患者实现了长期生存获益。本研究创新性地整合了不同类型的免疫治疗药物作用机制，并构建了综合性的疗效评估体系，为优化个体化治疗方案提供了理论依据，推动了肿瘤免疫治疗领域的进一步发展。

Abstract
Cancer immunotherapy, as an emerging therapeutic strategy, activates the body's own immune system to recognize and kill tumor cells, becoming an important treatment modality following surgery, radiotherapy, and chemotherapy. This study aims to thoroughly investigate the mechanisms of action and efficacy evaluation of drugs used in cancer immunotherapy, focusing on representative drug types such as immune checkpoint inhibitors, cytokine therapy, and adoptive cell therapy. By integrating literature review with clinical data analysis, this research systematically elucidates the entire process from laboratory development to clinical application of these drugs. Analysis of extensive clinical trial data reveals that immune checkpoint inhibitors can block immunosuppressive signaling pathways in the tumor microenvironment, restoring T-cell recognition of tumor cells; cytokine therapy modulates the activity of immune cells within the body, enhancing antitumor immune responses; and adoptive cell therapy provides patients with immune cells that have been modified ex vivo to exhibit enhanced specificity and cytotoxicity. The results demonstrate significant efficacy of these drugs in various solid tumors and hematological malignancies, with some patients achieving long-term survival benefits. Innovatively, this study integrates the mechanisms of action of different types of immunotherapy drugs and constructs a comprehensive efficacy evaluation system, providing theoretical basis for optimizing individualized treatment protocols and advancing the field of cancer immunotherapy.
