Combined targeted therapy and immunotherapy for cancer treatment

Although targeted therapies and immunotherapies have been effective againstseveral malignancies, the respective monotherapies are limited by low and/orshort-term responses. Specific inhibitors of oncogenic signaling pathways andtumor-associated angiogenesis can activate the anti-tumor immune responses byincreasing tumor antigen presentation or intratumor T cell infiltration. Additionalinsights into the effects and mechanisms of targeted therapies on the induction ofanti-tumor immunity will facilitate development of rational and effective combinationstrategies that synergize rapid tumor regression and durable response. Inthis review, we have summarized the recent combinations of targeted therapiesand immunotherapies, along with the associated clinical challenges.
