Current development and trends of cancer immunotherapy

Normally, Tumor cells are able to evade the body's immune system and stifle it using a variety of tactics, which enables them to endure through every phase of the immunological reaction against the tumor. This is because the immune system is capable of identifying and eliminating tumor cells within the tumor microenvironment. This article describes current and future trends in cancer treatment and cancer immunotherapy, as well as the specific processes that occur in the cancer immune cycle. A class of disorders known as cancer is distinguished by aberrant cell division and invasion potential. Cancer immunotherapy has shown immense potential and possibilities in recent years, and its research has grown increasingly focused due to advancements in science and technology. The host organism's immune system generates anticancer defences during tumour development through various progressive and combinatorial mechanisms hence the term cancer-immunity cycle. The aim of this article is to describe the basic process of the cancer immune cycle as well as the various immunotherapies that are commonly used in the clinical setting today, as well as trends and future prospects. This review discusses adoptive cell transfer, cytokine therapy, cancer vaccinations, oncolytic viral treatments, and immune checkpoint inhibitors.
