Study on the Mechanism of Immunoglobulin-Based Targeted Therapy in Tumor Immune Escape

Abstract

This article aims to explore the targeted therapy strategy based on immunoglobulin and its application and prospect in tumor immunotherapy. By reviewing the basic structure and classification of immunoglobulin, its role in immune system and its close relationship with tumor immunity, this article reveals the importance of immunoglobulin as a key molecule in immunotherapy. Furthermore, the principle of tumor immunotherapy with targeted immunoglobulin is expounded in detail, including specific methods such as immune checkpoint inhibitor therapy, antibody-coupled drug therapy and chimeric antigen receptor T cell therapy. At the same time, this article lists a variety of clinical application cases of cancer treatment, such as breast cancer, lymphoma and lung cancer, which shows the remarkable curative effect and wide application prospect of targeted therapy. Through the analysis of clinical data and the assessment of treatment effect, this article confirmed the remarkable effect of targeted therapy based on immunoglobulin in improving patient survival rate, tumor remission rate and quality of life. However, the follow-up still needs to be explored and optimized to achieve better therapeutic effects.
