The immune system is composed of immune organs, immune cells, and immunoactive substances, which plays a vital role in antitumor immunity in cancer immunotherapy. During the process of the antitumor immune response, many factors are involved in the cancer immune cycle. Therefore, developing intelligent strategies based on the steps of the cancer immune cycle to elicit the immune responses for enhanced cancer immunotherapy is of great significance. In this review, the key factors in each step of the cancer immune cycle are discussed, and then, the intelligent therapeutic strategies for modulating the immune surveillance against cancer are highlighted. Considering the demand for cancer immunotherapy in clinic, some suggestions for constructing new intelligent strategies are also put forward, which will make antitumor immunity more effective and advance the development of cancer immunotherapy.
