Abstract
INTRODUCTION: Compared with traditional cancer treatment methods, tumor-targeted immunotherapy can combine targeted therapy and immunotherapy with long-lasting responses to achieve synergistic therapy, which brings hope to the complete cure of cancer. AREAS COVERED: This review summarizes the newest and most up-to-date advances in tumor-targeted immunotherapy, including tumor-associated macrophages (TAMs) targeted immunotherapy, regulatory T (Treg) cells targeted immunotherapy, tumor-associated fibroblasts (TAFs) targeted immunotherapy and immune checkpoints targeted immunotherapy. EXPERT OPINION: Immunotherapy can restore anti-tumor immunity in the tumor microenvironment and produce a lasting immune surveillance effect. Smart multifunctional nano delivery system can effectively combine targeted therapy with immunotherapy, which has attracted extensive attention. With the deepening of research, more and more tumor-targeted immunotherapy enter into the clinical trial phases, especially antibodies and inhibitors. Tumor-targeted immunotherapy is a promising approach for conquering cancer and bringing hope for human health.
