Immunotherapy: How the Immune System Fights Cancer


Immunotherapy is an exciting area of cancer
research that is changing the way we think about cancer treatment. Immunotherapy works by using the body’s
immune system to fight cancer. The immune system is a complex network of
organs, tissues, and cells, and the substances they make. One of the purposes of the immune system is
to rid the body of germs, such as bacteria, and abnormal cells, such as cancer cells. Immunotherapy uses different ways to boost
the immune system to do a better job of killing cancer cells. This video describes three types of immunotherapy
that are used to treat cancer : non-specific immune stimulation, T-cell transfer therapy,
and immune checkpoint inhibitors. Non-specific immune stimulation is a type
of immunotherapy that stimulates a patient’s immune response in a general way. In non-specific immune stimulation, drugs
or other substances are used to increase the overall immune response, which can help kill
cancer cells. For example, some patients who have had surgery
to remove bladder cancer may also be treated with a substance called BCG. When BCG is put into the bladder, it can cause
a non-specific immune response that kills cancer cells that remain in the bladder after
surgery. This may keep the cancer from getting worse
or coming back. T-cell transfer therapy is another type of
immunotherapy. T cells are a type of immune cell and are
powerful weapons the immune system uses to fight cancer. For T-cell transfer therapy, T cells are taken
from a patient and changed in the laboratory to make them better able to target the patient’s
cancer cells and kill them. Millions of copies of these specially changed
T cells are then grown in the laboratory and given back to the patient to fight the cancer. Immune checkpoint inhibitors are a third type
of immunotherapy. Immune checkpoints on cell surfaces help control
an immune response. Usually immune checkpoints keep T cells inactive,
that is in an “off” state, until they are needed. This keeps the T cells from harming normal
cells. Cancer cells can take advantage of these checkpoints
to switch T cells off. This keeps the cancer cells from being killed. Immune checkpoint inhibitors are drugs that
block the checkpoints. This frees the T cells to attack the cancer. These three types of immunotherapy are effective
ways to treat cancer, but they don’t work for every patient and can cause serious side
effects. Researchers supported by the National Cancer
Institute are working to learn more about how the immune system works to fight cancer. By studying this, researchers can learn how
to improve immunotherapy for all patients.

  • My brother has been receiving a treatment of 4 rounds of one of these immunal therapy's. I am not sure which one it is. He is being treated for metastatic melanoma.

    These are $75,000 per treatment. He getting it for the 2nd time. The doctors are using this for a case study.. I believe he is either the first or one of the first to receive the 4 round therapy for the second time…

    We are praying and very hopefull. πŸ™

  • Does this fall on "tumor promoting immune activity" topic? Im a bit confuse.. Does tumor promoting immune activity is the same as tumor promoting inflammation?

  • Is there any treatment option for my mom..she was diagnosis with stage 4 Ca urinary bladder with bone metastasis last year then she received chemotherpy of 6 cycles of biogem 600mg and 27 radiotherpy out of 27 …22 on right actibruim bone and remaining 5 on bladder..but this year she had a pain in her left sife of kidney then we go for USG then it shows reccurence of disease and pet shows now left side of her urinary bladder and right iliac bone.. last year was right side .and in january 2019 Dr recommended again 4 cycles of chemothrpy D1 D15..Nab paclitaxel 230mg and gemcitabine 1500mg ..but no relief..and 3 Radiotherpy … but now recently we go for CECt Abdomen pelvis with urography..that reveals lytic lession on right iliac bone and liver metastasis..lung involment..uretus fundus..grade ‘‘ hydronephrosis of kidney..obstruction in kidney pipe….now please is there any immunothrpy treatment for her to recover

  • Great video. It's informative and got to learn a lot. Best wishes for All who are fighting cancer bravely. πŸ‘πŸ‘

  • Is this treatment something that’s referred by specialist that diagnosed the patient or does the patient needs to sign up by himself/herself at some particular website for treatment like this,only asking because this treatment Kinda looks more promising than a regular chemo therapy, correct me if I’m wrong, great video.
