How Does Immunotherapy Work?
Your immune system is a network of cells, tissues and organs that works together to recognize and destroy foreign invaders such as bacteria and viruses or abnormal or unhealthy cells in your body.
The most important function of the immune system is to know the difference between self and non-self. Self means your own body tissues. Non-self means any abnormal cell or foreign invader, such as bacteria, viruses, parasites and fungus. Normally, your immune system will not attack anything that it identifies as a healthy part of self. The problem with cancer cells is that they arise from our cells, but there are differences. As they grow and spread, cancer cells undergo a series of changes, or mutations, becoming increasingly less like normal cells. Sometimes our immune system can detect these differences and respond. Other times, the cancer cells slip through the defenses or are actually able to inhibit the immune system. Researchers have known for many years that our immune systems do recognize and attack cancer cells. But, the progress being made today in immunotherapy is the result of new understanding about the complex interaction between the immune system and cancer.
The goal of the field of immuno-oncology, also known as tumor immunology, is to understand exactly how the immune system interacts with the cancer, and then use that information to develop new immunotherapy treatments.
Eligibility & Side Effects
There is widespread interest and excitement throughout the cancer community about the potential for using immunotherapy for cancer. As researchers learn more about the interaction between our immune system and cancer, they will be able to apply that knowledge to more and more treatment options.
Who Is Eligible for Immunotherapy?
- Most people who receive immunotherapy today have cancers that are advanced.
- Their cancers have either recurred and spread after primary treatment, or were diagnosed with advanced stage cancers.
- At this time, most immunotherapy is still given in specialized cancer centers and mostly as part of a clinical trial.
- There are some people who cannot receive immunotherapy. These individuals often have health problems that make it impossible to take these drugs safely.
As the field of immunotherapy moves forward, researchers will begin new clinical trials with people who are at high risk for having their cancers recur or spread. If you are interested in immunotherapy, talk about your options with your doctor and treatment team.
