Cancer Immunotherapy: How the Body Fights Cancer Naturally

Our bodies possess a powerful weapon against diseases: the immune system. Composed of white blood cells, lymph system tissues, and organs, the immune system collaborates to identify and eliminate infections and abnormal cells. Cancer cells, however, leverage genetic changes to evade detection and destruction by the immune system, prompting the need for immunotherapy to bolster the body’s natural defenses.

Mayo Clinic doctors, such as Svetomir Markovic, M.D., Ph.D., and Haidong Dong, M.D., Ph.D., expound on the rationale behind immunotherapy – to enhance the immune system’s cancer-fighting capabilities. By utilizing tools like T cells, vaccines, and targeted drugs, immunotherapy harnesses the patient’s immune cells to combat tumors effectively. In essence, the treatment strengthens the body’s ability to detect and eradicate cancer cells actively.

The History and Progress of Cancer Immunotherapy

In the late ’90s, a breakthrough was made at Mayo Clinic by Dr. Dong and his team with the discovery of PD-L1, a protein that regulates the immune system’s response to cancer cells. By obstructing PD-L1’s function with an antibody, the immune system’s ability to eliminate tumors is restored. This milestone laid the groundwork for immune checkpoint inhibitors, a type of immunotherapy drug that targets the PD-L1 pathway. The FDA’s approval of pembrolizumab in 2014 marked the first immune checkpoint inhibitor, initially for melanoma treatment, now extended to treat 18 cancer types.

How Cancer Immunotherapy Operates

Unlike conventional cancer treatments that directly target cancer cells, immunotherapy enhances the immune system’s armored cells, enabling them to identify and destroy cancer cells effectively. The treatment enables the immune system to pinpoint cancer cells in the body, a power that significantly bolsters the therapeutic outcome. Typically, immunotherapy acts as a mediator for the immune system, equipping it with the tools necessary to combat cancer effectively.

Types of Immunotherapies in Cancer Treatment:

**Immune Checkpoint Inhibitors

• Pembrolizumab
• Clinical trials exploring new immune checkpoint inhibitors

**Oncolytic Viruses

• Utilizing viruses to rupture cancer cells and stimulate an immune response

**Personalized Cancer Vaccines

• Training the immune system to combat cancer-related proteins
• Ongoing clinical trials related to personalized cancer vaccines

**Cellular Therapies

• Car-T Cell Therapy
• TIL Therapy

**Cytokines

• Use of cytokines like interleukins and interferons

**Bispecific Antibodies

• Creating antibodies to enhance an immune response against cancer cells

Benefits and Risks of Immunotherapy

Immunotherapy’s effectiveness lies in leveraging the body’s immune system to recognize and address cancer cells, resulting in enduring responses and potential cures. However, the treatment’s side effects can mimic autoimmune disease symptoms as the immune system may attack normal tissues while targeting cancer. Managing these side effects is crucial for safe treatment, prompting ongoing research to optimize the treatment modality.

The Future of Cancer Immunotherapy

The frontier of cancer immunotherapy research is geared towards improving outcomes, minimizing limitations, and maximizing benefits. By understanding individualized responses, combining treatment modalities, reducing side effects, and identifying biomarkers, researchers aim to revolutionize cancer treatment. The promise of more effective, less toxic, and widely beneficial immunotherapy underscores the potential to transform cancer treatment outcomes significantly.

In essence, the transformative impact of cancer immunotherapy on the landscape of cancer medicine heralds the dawn of curative possibilities for once deemed incurable cancers. The dawn of personalized and effective cancer treatment under the aegis of immunotherapy opens a new chapter in the battle against cancer. As our understanding of the biological intricacies deepens, so too does the scope of cancer types we can combat effectively and the magnitude of lives we can impact positively.
