Objective:
Cancer is one of the most complex genomic diseases that can gain abilities to resist different therapies. These capabilities, known as the hallmark of cancer, allow specific and personalised therapies such as immunotherapy.
Materials And Methods:
This review paper discusses how different immunotherapies, such as immune checkpoint blockade, chimeric antigen receptor (CAR) T-cell, and Oncolytic viral therapy, which are currently being used and researched to overcome cancer cell capabilities by using the patient's immune system.
Results:
Immune checkpoint blockade therapy is used to block immune inhibitory pathways using anti-PD-1 receptor and anti-CTLA-4 receptor antibodies, which make lymphocytes more responsive towards cancer cells. Then, it is discussed how CAR T-cells are designed to make cancer antigens more easily identified by T-cells for a more specific immune response. Furthermore, it is shown that oncolytic viruses directly destroy cancer cells and, indirectly, make them more vulnerable to the immune system.
Conclusion:
It is proposed that oncolytic viral therapy is a bridge between Immune checkpoint and CAR T-cell therapies for a more effective and more specific immune response towards cancer.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
