Biological Therapy or Immunotherapy for Waldenstrom Macroglobulinemia

Nov 13,  · Biological therapy for cancer is a type of treatment that uses the body's immune system to kill cancer cells. Biological therapy for cancer is used in the treatment of many types of cancer to prevent or slow tumor growth and to prevent the spread of cancer. Biological therapy (also called immunotherapy, biological response modifier therapy, or biotherapy) uses the body's immune system to fight cancer. The cells, antibodies, and organs of the immune system work to protect and defend the body against foreign invaders, such as bacteria or viruses.

Chemotherapy and biotherapy are both used to destroy cancer cells. So how are they different, and how are they similar? Traditional chemotherapy uses chemical substances to treat cancer. Biological therapy, by contrast, uses living organisms, substances derived from organisms, or laboratory-made versions of those substances to act against cancer cells. Most chemotherapy drugs — formally known as cytotoxic cell-killing agents — work by destroying cancer cells directly, often by damaging their DNA and causing them switch on their programmed death process, apoptosis.

Because ks of these dor can also damage normal cells, they often produce side effects such as nausea, fatigue, and hair loss, or other complications, depending on the specific agents used. Chemotherapy drugs are often used to kill cancer cells that are dispersed throughout the body or have spread to multiple sites. They may also be used to shrink how to build a square keep castle tumor before surgery or radiation treatmentdestroy cancer cells that remain after surgery or radiation therapy, or help radiation and biological therapies work better.

Biological therapies biotherapies, for short may either attack tumor waht directly or, by stimulating the immune system, target them indirectly. The side effects of biological therapies can vary widely, both in type and intensity. Pain, swelling, soreness, redness, itchiness, and rash at the site of infusion or injection are fairly common, but other side effects can be more severe.

The first expressly biological therapy to be approved by the U. It was first used as a vaccine against tuberculosis, but scientists later found that when inserted directly into the bladder, it stimulates a broad immune response not only against the foreign bacterium but against bladder cancer cells as well. Approximately 70 percent of patients with early-stage bladder cancer experience a remission after BCG therapy.

It is currently being studied for the treatment of additional types of cancer. An experimental biotherapy known as oncolytic virus therapy uses specific kinds of viruses that infect both cancerous and normal cells but do no damage to normal cells. In cancer cells, by contrast, they readily reproduce and ultimately cause the cells to die.

Some viruses are naturally oncolytic — biloogical is, destructive to cancer cells — while others can be modified to have oncolytic features. Although no oncolytic virus has been approved for use in the United States, several such viruses are currently being tested in clinical trials.

Immunotherapy is a type of biological therapy. Biological therapy is a type of treatment that uses substances made from living organisms to treat cancer. Nov 13,  · Mayo Clinic doctors have access to the latest biological therapy treatments approved for people with cancer, including CAR T-cell therapy. Your cancer treatment plan will take into account the most up-to-date information. In addition, many biological . There are two basic categories of biological therapy: immunotherapy and cytotoxic therapy. Immunotherapy uses a variety of methods and drugs to manipulate the immune system. This creates a hostile environment for the existence or growth of cancer in the body.

At Beaumont, our cancer specialists are leading the way in innovative diagnosis and treatment methods to battle cancer. Among the treatment options available is biological therapy, which uses the body's immune system to fight the disease. Biological therapy also called immunotherapy, biological response modifier therapy, or biotherapy uses the body's immune system to fight cancer. The cells, antibodies, and organs of the immune system work to protect and defend the body against foreign invaders, such as bacteria or viruses.

Physicians and researchers have found that the immune system might also be able to both determine the difference between healthy cells and cancer cells in the body, and to eliminate the cancer cells. Biological therapies are designed to boost the immune system, either directly or indirectly, by assisting in the following:. The immune system includes different types of white blood cells - each with a different way to fight against foreign or diseased cells, including cancer:.

These types of white blood cells - B cells, T cells, natural killer cells, and monocytes - are in the blood and thus circulate to every part of the body, providing protection from cancer and other diseases. Cells secrete two types of substances: antibodies and cytokines. Antibodies respond to harmful substances that they recognize, called antigens.

Specific helpful antibodies match specific foreign antigens by locking together. Cytokines are proteins produced by some immune system cells and can directly attack cancer cells. Cytokines are "messengers" that "communicate" with other cells. Biological response modifiers BRMs change the way the body's defenses interact with cancer cells.

BRMs are produced in a laboratory and given to patients to:. BRMs include nonspecific immunomodulating agents, interferons, interleukins, colony-stimulating factors, monoclonal antibodies, cytokine therapy, and vaccines:.

Side effects may be severe, mild, or absent. Side effects of biological therapy, which often mimic flu-like symptoms, vary according to the type of therapy given and may include the following:. Specifically, cytokine therapy often causes fever, chills, aches, and fatigue.

Other side effects include a rash or swelling at the injection site. Therapy can cause fatigue and bone pain and may affect blood pressure and the heart. What is biological therapy? Biological therapies are designed to boost the immune system, either directly or indirectly, by assisting in the following: making cancer cells more recognizable by the immune system, and therefore more susceptible to destruction by the immune system boosting the killing power of immune system cells changing the way cancer cells grow, so that they act more like healthy cells stopping the process that changes a normal cell into a cancerous cell enhancing the body's ability to repair or replace normal cells damaged or destroyed by other forms of cancer treatment, such as chemotherapy or radiation preventing cancer cells from spreading to other parts of the body How does the immune system fight cancer?

The immune system includes different types of white blood cells - each with a different way to fight against foreign or diseased cells, including cancer: lymphocytes - white blood cells, including B cells, T cells, and NK cells. B cells - produce antibodies that attack other cells. T cells - directly attack cancer cells themselves and signal other immune system cells to defend the body.

What are the different types of biological therapies? There are many different types of biological therapies used in cancer treatment. BRMs are produced in a laboratory and given to patients to: boost the body's ability to fight the disease. BRMs include nonspecific immunomodulating agents, interferons, interleukins, colony-stimulating factors, monoclonal antibodies, cytokine therapy, and vaccines: nonspecific immunomodulating agents Nonspecific immunomodulating agents are biological therapy drugs that stimulate the immune system, causing it to produce more cytokines and antibodies to help fight cancer and infections in the body.

Fighting infection is important for a person with cancer. They are also produced in the laboratory and given to cancer patients in biological therapy. They have been shown to improve the way a cancer patient's immune system acts against cancer cells. Interferons may work directly on cancer cells to slow their growth, or they may cause cancer cells to change into cells with more normal behavior.

Some interferons may also stimulate natural killer cells NK cells, T cells, and macrophages - types of white blood cells in the bloodstream that help to fight cancer cells. They are proteins cytokines that occur naturally in the body, but can also be made in the laboratory. Some interleukins stimulate the growth and activity of immune cells, such as lymphocytes, which work to destroy cancer cells.

The body constantly needs new white blood cells, red blood cells, and platelets, especially when cancer is present. CSFs are given, along with chemotherapy, to help boost the immune system. When cancer patients receive chemotherapy, the bone marrow's ability to produce new blood cells is suppressed, making patients more prone to developing infections.

Parts of the immune system cannot function without blood cells, thus colony-stimulating factors encourage the bone marrow stem cells to produce white blood cells, platelets, and red blood cells. With proper cell production, other cancer treatments can continue enabling patients to safely receive higher doses of chemotherapy. When cancer-destroying agents are introduced into the body, they seek out the antibodies and kill the cancer cells. Monoclonal antibody agents do not destroy healthy cells.

Cytokines are produced naturally in the body by the immune system, but can also be produced in the laboratory. This therapy is used with advanced melanoma and with adjuvant therapy therapy given after or in addition to the primary cancer treatment.

Cytokine therapy reaches all parts of the body to kill cancer cells and prevent tumors from growing. The benefit of vaccine therapy has not yet been proven. With infectious diseases, vaccines are given before the disease develops.

Cancer vaccines, however, are given after the disease develops, when the tumor is small. Scientists are testing the value of vaccines for melanoma and other cancers. Sometimes, vaccines are combined with other therapies such as cytokine therapy.

Are there side effects of biological therapies? Side effects of biological therapy, which often mimic flu-like symptoms, vary according to the type of therapy given and may include the following: fever chills nausea vomiting loss of appetite fatigue Specifically, cytokine therapy often causes fever, chills, aches, and fatigue.
