Wake Forest Baptist Medical Center is a leader in immunotherapy for cancer treatment, including oral immunotherapy, cancer vaccines and treatments administered intravenously.

What Is Immunotherapy?

Immunotherapy is the practice of using your immune system to fight cancer. This cancer treatment allows your body’s immune system to more effectively target and destroy cancerous cells in your body.

How Does Immunotherapy Work?

Cancer cells can confuse your immune system, making it hard to tell healthy cells from cancerous mutated cells. Immunotherapy helps your immune response, so your natural antibodies better detect and attack cancer cells.

Immunotherapy works by:

  • Stopping or slowing the growth of cancer cells
  • Preventing cancer from spreading to other parts of the body
  • Boosting the immune system's ability to get rid of cancer cells

Sometimes immunotherapy cancer treatments may be used concurrently with chemotherapy, hormone therapy or surgical oncology.

How Effective Is Immunotherapy for Treating Cancer?

How effective your immunotherapy treatment is likely to be depends on many factors including the type of cancer, its stage, your genetic factors and tumor biomarkers.

Immunotherapy vs. Chemotherapy

Whether or not to use immunotherapy, chemotherapy or a combination of the two is for you and your care team to determine. Immunotherapy can be helpful if your current cancer treatment stops being as effective as it once was or in instances where cancer cells return and spread.

Types of Immunotherapy Cancer Treatment

There are several types of immunotherapies for cancer.

Adoptive Cell Therapy

Adoptive cell therapy, or cellular immunotherapy, activates T cells that have already attacked cancer cells, reinfusing them to seek out and destroy tumors.

Cancer Vaccines

Cancer vaccines train the body to attack cancer cells already in the body.

Immune Checkpoint Inhibitors

While immune checkpoint inhibitors help your body target cancerous cells, these immunotherapy drugs target different “checkpoint” proteins in cancer cells, which helps your white blood cells better identify cancer cells to attack.

Immune System Modulators

Immune system modulators are a group of immunotherapy drugs that range in form and in the way they attack different types of cancer. For example, bladder cancer is treated with a liquid immune system modulator that’s put into the bladder using a catheter to attack cancer cells.

Monoclonal Antibodies

Monoclonal antibodies mimic actual antibodies and attack cancer cells.

Side Effects of Immunotherapy

The side effects for different types of immunotherapy for cancer differ by the type of treatment. Some side effects occur where the injection or IV enters the body, causing the area to be:

  • Sore or painful
  • Swollen
  • Red
  • Itchy

Other possible side effects include:

  • Flu-like symptoms (fever, chills, weakness, headache)
  • Nausea and vomiting
  • Diarrhea
  • Muscle or joint aches
  • Feeling very tired
  • Headache
  • Low or high blood pressure

These therapies can also cause a severe, sometimes fatal, allergic reaction in people sensitive to certain ingredients in the treatment. However, this is very rare.
