1. Understanding Cancer Immunotherapy
Cancer immunotherapy, also known as immuno-oncology, is a type of cancer treatment that uses the body’s own immune system to help fight cancer. The immune system normally defends the body against infections and other diseases. It attacks foreign cells, but it does not always recognize cancer cells as foreign. Immunotherapy can help the immune system recognize and attack cancer cells.
1.1. The Immune System and Cancer
The immune system is a complex network of cells, tissues, and organs that work together to protect the body from harm. It identifies and attacks foreign invaders like bacteria, viruses, and parasites. However, cancer cells can sometimes evade the immune system by:
- Hiding from immune cells: Some cancer cells have surface proteins that prevent immune cells from recognizing them.
- Suppressing immune responses: Cancer cells can release substances that inhibit the activity of immune cells.
- Developing resistance: Over time, cancer cells can become resistant to immune attack.
Immunotherapy aims to overcome these challenges by boosting the immune system’s ability to recognize and destroy cancer cells.
1.2. How Immunotherapy Works
Immunotherapy works by stimulating the immune system to attack cancer cells. There are several different types of immunotherapy, but they all work by helping the immune system to better recognize and destroy cancer cells. This can involve:
- Boosting the immune system’s overall activity: Some immunotherapies stimulate the immune system in a general way, making it more active and better able to fight cancer.
- Training the immune system to recognize cancer cells: Other immunotherapies help the immune system to specifically identify and target cancer cells.
- Providing the immune system with tools to attack cancer cells: Certain immunotherapies provide the immune system with antibodies or cells that can directly attack cancer cells.
1.3. History and Evolution of Immunotherapy
The concept of using the immune system to fight cancer dates back to the late 19th century. William Coley, a New York surgeon, observed that some cancer patients who developed infections after surgery experienced tumor regression. He began injecting patients with bacteria to stimulate their immune systems, achieving some success.
However, immunotherapy remained a niche field for many years. It wasn’t until the late 20th and early 21st centuries that significant breakthroughs occurred. These included the discovery of immune checkpoints, which are molecules that regulate the immune system’s activity. The development of immune checkpoint inhibitors, drugs that block these checkpoints, revolutionized cancer treatment.
1.4. Why Immunotherapy Is Different
Immunotherapy differs from traditional cancer treatments like chemotherapy and radiation therapy in several key ways:
- Mechanism of Action: Immunotherapy targets the immune system, while chemotherapy and radiation therapy directly target cancer cells.
- Side Effects: Immunotherapy can cause different side effects than chemotherapy and radiation therapy. Immune-related side effects can occur in any part of the body.
- Durability of Response: Immunotherapy can sometimes lead to long-lasting responses, even after treatment has stopped. This is because the immune system can “remember” cancer cells and continue to attack them.
- Specificity: Immunotherapy can be more specific than chemotherapy and radiation therapy, targeting cancer cells while sparing healthy cells.
2. Types of Cancer Immunotherapy
There are several different types of cancer immunotherapy, each with its own mechanism of action and applications.
2.1. Immune Checkpoint Inhibitors
Immune checkpoints are molecules on immune cells that help to regulate the immune response. They prevent the immune system from becoming overactive and attacking healthy cells. However, cancer cells can sometimes exploit these checkpoints to evade immune attack.
Immune checkpoint inhibitors are drugs that block immune checkpoints, allowing the immune system to attack cancer cells more effectively. Some common immune checkpoint inhibitors include:
- Anti-CTLA-4 antibodies: These antibodies block CTLA-4, a checkpoint protein on T cells.
- Anti-PD-1 antibodies: These antibodies block PD-1, another checkpoint protein on T cells.
- Anti-PD-L1 antibodies: These antibodies block PD-L1, a protein on cancer cells that binds to PD-1.
Immune checkpoint inhibitors have shown remarkable success in treating a variety of cancers, including melanoma, lung cancer, kidney cancer, and bladder cancer. Pembrolizumab, nivolumab, atezolizumab, and ipilimumab are common medications.
2.2. T-Cell Transfer Therapy
T-cell transfer therapy involves removing T cells from a patient’s blood, modifying them in the laboratory to better recognize cancer cells, and then infusing them back into the patient. This type of immunotherapy is also known as adoptive cell transfer.
There are two main types of T-cell transfer therapy:
- CAR T-cell therapy: In CAR T-cell therapy, T cells are genetically engineered to express a chimeric antigen receptor (CAR) on their surface. This receptor allows the T cells to recognize and bind to a specific protein on cancer cells.
- Tumor-infiltrating lymphocyte (TIL) therapy: In TIL therapy, T cells that have infiltrated a patient’s tumor are isolated, expanded in the laboratory, and then infused back into the patient.
T-cell transfer therapy has shown great promise in treating certain blood cancers, such as leukemia and lymphoma.
2.3. Monoclonal Antibodies
Monoclonal antibodies are laboratory-produced antibodies that are designed to bind to specific proteins on cancer cells. They can work in several ways:
- Blocking cancer cell growth: Some monoclonal antibodies block growth factor receptors on cancer cells, preventing them from growing and dividing.
- Marking cancer cells for destruction: Other monoclonal antibodies mark cancer cells for destruction by the immune system.
- Delivering toxins to cancer cells: Some monoclonal antibodies are linked to toxins that kill cancer cells.
Examples of monoclonal antibodies used in cancer treatment include trastuzumab, rituximab, and cetuximab.
2.4. Oncolytic Virus Therapy
Oncolytic viruses are viruses that selectively infect and kill cancer cells. They can also stimulate the immune system to attack cancer cells.
When an oncolytic virus infects a cancer cell, it replicates inside the cell, eventually causing the cell to burst and die. This process releases viral particles that can infect other cancer cells, as well as cancer-associated antigens that can stimulate the immune system.
Talimogene laherparepvec (T-VEC) is an example of an oncolytic virus that is approved for the treatment of melanoma.
2.5. Cancer Vaccines
Cancer vaccines are designed to stimulate the immune system to recognize and attack cancer cells. They can be used to prevent cancer from developing (preventive vaccines) or to treat existing cancer (therapeutic vaccines).
Therapeutic cancer vaccines typically contain cancer-associated antigens, which are proteins or other molecules that are found on cancer cells but not on normal cells. When the vaccine is injected into the body, the immune system recognizes these antigens and mounts an immune response against cancer cells.
Sipuleucel-T is an example of a therapeutic cancer vaccine that is approved for the treatment of prostate cancer.
2.6. Cytokines
Cytokines are proteins that help regulate the immune system. Some cytokines, such as interferon and interleukin-2, have been used to treat cancer.
- Interferon: Interferon can stimulate the activity of immune cells and inhibit the growth of cancer cells.
- Interleukin-2: Interleukin-2 can stimulate the growth and activity of T cells and other immune cells.
Cytokines can cause significant side effects, so they are typically used in carefully selected patients.
3. The Role of the Microbiome in Immunotherapy
The gut microbiome, the community of microorganisms that live in the digestive tract, plays a crucial role in regulating the immune system. Recent research has shown that the microbiome can influence the effectiveness of cancer immunotherapy.
3.1. The Gut Microbiome and Immune Response
The gut microbiome can affect the immune system in several ways:
- Stimulating immune cell development: The microbiome can stimulate the development and maturation of immune cells in the gut.
- Modulating immune cell activity: The microbiome can influence the activity of immune cells, making them more or less responsive to cancer cells.
- Producing metabolites that affect the immune system: The microbiome produces a variety of metabolites that can affect the immune system.
3.2. Microbiome and Immunotherapy Efficacy
Studies have shown that the composition of the gut microbiome can affect the effectiveness of immunotherapy. Patients with a diverse and healthy microbiome tend to respond better to immunotherapy than patients with a less diverse or unhealthy microbiome.
Specific types of bacteria in the gut have been linked to improved responses to immunotherapy. For example, some studies have shown that patients with higher levels of Akkermansia muciniphila in their gut respond better to immune checkpoint inhibitors.
3.3. Modulating the Microbiome to Enhance Immunotherapy
Researchers are exploring ways to modulate the microbiome to enhance the effectiveness of immunotherapy. Strategies include:
- Fecal microbiota transplantation (FMT): FMT involves transferring fecal material from a healthy donor to a patient to restore a healthy microbiome.
- Probiotics: Probiotics are live microorganisms that are intended to benefit the host.
- Dietary interventions: Dietary changes can alter the composition of the gut microbiome.
Further research is needed to determine the best ways to modulate the microbiome to improve immunotherapy outcomes.
4. Cancer Types Treated with Immunotherapy
Immunotherapy has shown success in treating a variety of cancers, including:

8. Biomarkers for Immunotherapy Response
Biomarkers are measurable indicators that can be used to predict how a patient will respond to immunotherapy.
8.1. PD-L1 Expression
PD-L1 is a protein on cancer cells that binds to PD-1 on T cells. High levels of PD-L1 expression in tumors have been associated with a better response to anti-PD-1 therapy in some cancers.
8.2. Tumor Mutational Burden (TMB)
Tumor mutational burden (TMB) is a measure of the number of mutations in a tumor’s DNA. Tumors with high TMB have been associated with a better response to immunotherapy in some cancers.
8.3. Microsatellite Instability (MSI)
Microsatellite instability (MSI) is a condition in which there are changes in the length of microsatellites, which are short, repetitive sequences of DNA. Tumors with MSI have been associated with a better response to immunotherapy in some cancers.
8.4. Other Biomarkers
Researchers are investigating other biomarkers that may be useful for predicting immunotherapy response, including:
- Immune cell infiltration in the tumor
- Cytokine levels in the blood
