Revolutionizing cancer treatment: the rise of personalized immunotherapies

Abstract

Interest in biological therapy for cancer has surged due to its precise targeting of cancer cells and minimized impact on surrounding healthy tissues. This review discusses various biological cancer therapies, highlighting advanced alternatives over conventional chemotherapy alone. It explores DNA and RNA-based vaccines, T-cell modifications, adoptive cell transfer, CAR T cell therapy, angiogenesis inhibitors, and the combination of immunotherapy with chemotherapy, offering a holistic view of the potential in cancer treatment. Additionally, it discusses the role of nanotechnology in increasing the efficacy of cancer-targeting drugs, as well as cytokine and immunoconjugate therapies for bolstering immune system effectiveness against neoplastic cells. The potential of gene potential for precise targeting of cancer-linked genes and the application of oncolytic viruses against virus-associated cancers are also discussed. The review identifies significant advancements in the targeted treatment of cancer by biological methods. It acknowledges the challenges, including drug resistance and the need for high specificity in certain therapies, while also highlighting the effectiveness of cancer vaccines, modified T-cells, and oncolytic viruses. Biological therapies are a promising frontier in cancer treatment, offering the potential for more personalized and effective therapeutic strategies. Despite existing challenges, ongoing research and clinical trials are fundamental for overcoming current limitations and enhancing the efficacy of biological therapies in cancer care.
