What is Immunotherapy?
Immunotherapy utilizes the body’s immune system to combat cancer by helping it recognize and attack cancer cells. This treatment can be administered alone or in conjunction with other cancer therapies. While it is a standard approach for certain cancers, it is still undergoing trials for others.
There are several types of immunotherapy, including monoclonal antibodies, checkpoint inhibitors, and vaccines. Some immunotherapies are also referred to as targeted treatments or biological therapies.
The Immune System and Immunotherapy
The immune system plays a crucial role in protecting the body from infections, diseases, and potentially cancer. It comprises lymph glands, the spleen, and white blood cells, which usually identify and destroy abnormal cells, preventing cancer from developing. However, cancer can arise when:
- The immune system detects cancer cells but lacks the strength to eliminate them.
- Cancer cells emit signals that inhibit the immune response.
- Cancer cells manage to evade detection by the immune system.
Immunotherapy enhances the immune system's ability to fight cancer through various treatment methods that enable it to recognize and target cancer cells effectively.
Why Might You Consider Immunotherapy?
While immunotherapy is not appropriate for all cancer types, it is a primary treatment for several. Researchers are also exploring its use in clinical trials for additional cancer types. It can be used alone or alongside other treatments, such as surgery, chemotherapy, or radiotherapy. The decision to pursue immunotherapy depends on factors including:
- The specific type of cancer.
- The extent of cancer spread (stage).
- Prior treatments received.
Testing
Before starting certain immunotherapy treatments, you may need tests involving your cancer cells or a blood sample to determine the likelihood of treatment success. These tests check for specific protein or gene changes. Your cancer specialist will inform you if such testing is necessary, as it does not apply to all immunotherapies. A biopsy may be required to obtain a sample of your cancer cells, possibly using tissue from a previous procedure.
Types of Immunotherapy
Immunotherapy treatments often do not fit neatly into specific categories, as some drugs may function in multiple ways. For instance, checkpoint inhibitors can also be classified as monoclonal antibodies or targeted treatments.
For more information, we provide resources on various immunotherapies, including:
- Monoclonal antibodies
- Checkpoint inhibitors
- Vaccines
- Cytokines
- CAR-T cell therapy
Consult your specialist to discuss whether immunotherapy is suitable for you, the intended goals of treatment, the process involved, and potential side effects.
Conclusion
Immunotherapy represents a significant advancement in cancer treatment, offering hope for many patients. By leveraging the body’s own immune system, this approach aims to improve outcomes and enhance the quality of life for those battling cancer. As research continues to evolve, immunotherapy may expand its reach and effectiveness, providing new options for patients facing various types of cancer.
