Book excerpt: Traditionally, surgery, radiotherapy, chemotherapy and hormonal therapy have been used in clinical practice to treat cancer patients. However, these methods are either not completely tumor free or without collateral damage to health tissues. Therefore, tumor recurrence, partial remission, treatment side effect and poor tolerance in elderly patients, and lack of effective strategy to treat late-stage cancers have been the major hurdles faced by clinicians in health care. Although cancer immunotherapy including checkpoint blockade, CAR-T, oncolytic viruses, and recombinant cytokines has taken center stage in mainstream oncology because of its specifically targeting tumor cells without affecting surrounding normal cells, only a proportion of patients receiving treatment respond and others relapse after an initial response. Different tumor indications respond differently, and even in cancer types that respond, unresponsiveness are still observed. This resistance suggests that either lack of sufficient host recognition and immunity (intrinsic) or active immune suppression by tumor complex (acquired).
