CAR-T Cell Therapy: Pioneering Immunotherapy Paradigms in Cancer Treatment

Abstract

The world's one of the major causes of death are cancer. Cancer is still a complex disease over the years that needs to be cured. Traditional cytotoxic approaches, although they have been implemented for years for treating neoplastic diseases, yet are limited due to the intricacy and low efficiency of cancer cells. Researchers are thus compelled to seek more potent therapeutic strategies. Chimeric antigen receptor (CAR-T) cell therapy is one such innovative insight where T lymphocytes are altered genetically to target cancer cells. Despite the outstanding accomplishment in patients with haematological malignancies, CAR-T cell treatment has demonstrated minimal impact on solid tumours due to a number of obstacles, including proliferation, stability, trafficking, and fate within tumors. Furthermore, interactions between the host and tumour microenvironment with CAR-T cells significantly alter CAR-T cell activities. Designing and implementing these treatments additionally also requires a complex workforce. Overcoming these significant challenges, there is a requirement for innovative strategies for developing CAR-T cells with greater anti-tumour efficacy and reduced toxicity. In this chapter, the current advancement in CAR-T cell technology in order to increase clinical efficacy in both solid tumors and haematological, as well as possibilities to conquer the limits of CAR-T cell therapy in both solid and haematological tumours has been discussed.
