What is Cell Treatment?
What is cell treatment?
Cell therapy is a type of cancer treatment that uses your own immune system to
attack the tumor. This can be done by using a special type of T cell called a CAR T-
cell, or by injecting your own immune cells into the body frontalreporter. This is known as
immunotherapy or adoptive cell transfer.
The cells used in these types of treatments are called hematopoietic stem cells
(blood-forming stem cells). These are derived from the bone marrow and blood, and
are often used to treat cancer or other disorders that affect the blood or immune
system. These cells are also used in a type of cancer treatment that is FDA
approved for limited use in children, called bone marrow transplants.
Bone marrow transplants have become very successful for treating many kinds of
cancers, including leukaemia and lymphoma. However, there are some people who
have certain diseases that make it hard to get a bone marrow transplant. This is
called a chronic myelomonocytic leukaemia or CMML.
CMML is caused by a genetic mutation in your immune system. Luckily, this gene
can be fixed with special medicines that can help your immune cells fight CMML.
These medicines are usually given through a tube in the mouth or in your arm,
which is called an intravenous (IV) catheter.
To prepare for a cellular therapy, you will need to have a special procedure called
leukapheresis. This involves getting a needle into the pelvic bones and removing a
small amount of bone marrow from the hip area. This bone marrow is then sent to
the laboratory and a concentrate of stem cells is made from the stem cells in your
hip bone marrow.
In the laboratory, the T cells are changed by adding a gene that makes them a
chimeric antigen receptor (CAR). This new receptor recognises and targets a specific
protein on the cancer cells in your body. The CAR T cells then grow and multiply in
the lab. Once they have a large number of these new CAR T cells, they are then
injected into your blood.
Before getting a cellular therapy, it is important to ask your doctor about any risks
and side effects of the procedure. This information will help you make an informed
decision about the treatment and whether it is right for you.
There are risks associated with all medical treatments, including cellular therapies,
but some are more dangerous than others. For example, some unproven stem cell
therapies can lead to severe adverse events in patients.
These adverse events include vision problems, organ failure, and life-threatening
complications. If you have a serious medical problem, contact your healthcare
provider or local hospital right away.
If you have a stem cell clinical trial, you should know that this is an experimental
treatment. You should ask if the treatment is approved by the Food and Drug
Administration for use in humans, and if the clinical investigator has submitted an
investigational new drug application (IND) to the FDA. If the clinical investigator has
not submitted an IND, the therapy is not reviewed by the FDA.
