Abstract

Although targeted therapies and immunotherapies have been effective against several malignancies, the respective monotherapies are limited by low and/or short-term responses. Specific inhibitors of oncogenic signaling pathways and tumor-associated angiogenesis can activate the anti-tumor immune responses by increasing tumor antigen presentation or intratumor T cell infiltration. Additional insights into the effects and mechanisms of targeted therapies on the induction of anti-tumor immunity will facilitate development of rational and effective combination strategies that synergize rapid tumor regression and durable response. In this review, we have summarized the recent combinations of targeted therapies and immunotherapies, along with the associated clinical challenges.

Keywords: Cancer, Targeted therapy, Immunotherapy, Combined treatment

Core Tip: There has been considerable interest in combining systemic and immune-related therapies for the anti-tumor treatment of cancer. Additional insights into the effects and mechanisms of targeted therapies on the induction of anti-tumor immunity will aid the development and design of effective strategies, with the synergistic potential for rapid tumor regression and a durable response. Targeting specific signaling pathways may help in overcoming the mechanisms of immunotherapy resistance. We briefly review the immunomodulatory effects of targeted therapies and immunotherapies and discuss the obstacles associated with them, which may be useful for the development of novel basic research or clinical trials.
