There
are different types of treatment for patients with malignant
mesothelioma.
Different types of treatments are
available for patients with malignant mesothelioma. Some
treatments are standard (the currently used treatment), and some
are being tested in clinical trials. Before starting treatment,
patients may want to think about taking part in a clinical
trial. A treatment clinical trial is a research study meant to
help improve current treatments or obtain information on new
treatments for patients with cancer. When clinical trials show
that a new treatment is better than the standard treatment, the
new treatment may become the standard treatment.
Clinical trials are taking
place in many parts of the country. Information about ongoing
clinical trials is available from the
NCI Web site.
Choosing the most appropriate cancer treatment is a decision
that ideally involves the patient, family, and health care team.
Three
types of standard treatment are used:
Surgery
The following surgical
treatments may be used for malignant mesothelioma:
- Wide
local excision: Surgery to remove the cancer and some of the
healthy tissue around it.
-
Pleurectomy and decortication: Surgery to remove part of the
covering of the lungs and lining of the chest and part of
the outside surface of the lungs.
-
Extrapleural pneumonectomy: Surgery to remove one whole lung
and part of the lining of the chest, the diaphragm, and the
lining of the sac around the heart.
-
Pleurodesis: A surgical procedure that uses chemicals or
drugs to make a scar in the space between the layers of the
pleura. Fluid is first drained from the space using a
catheter or chest tube and the chemical or drug is put into
the space. The scarring stops the build-up of fluid in the
pleural cavity.
Even if the doctor removes
all the cancer that can be seen at the time of the surgery, some
patients may be given chemotherapy or radiation therapy after
surgery to kill any cancer cells that are left. Treatment given
after surgery, to increase the chances of a cure, is called
adjuvant therapy.
Radiation therapy
Radiation therapy is a
cancer treatment that uses high-energy x-rays or other types of
radiation to kill cancer cells. There are two types of radiation
therapy. External radiation therapy uses a machine outside the
body to send radiation toward the cancer. Internal radiation
therapy uses a radioactive substance sealed in needles, seeds,
wires, or catheters that are placed directly into or near the
cancer. The way the radiation therapy is given depends on the
type and stage of the cancer being treated.
Chemotherapy
Chemotherapy is a cancer
treatment that uses drugs to stop the growth of cancer cells,
either by killing the cells or by stopping the cells from
dividing. When chemotherapy is taken by mouth or injected into a
vein or muscle, the drugs enter the bloodstream and can reach
cancer cells throughout the body (systemic chemotherapy). When
chemotherapy is placed directly into the spinal column, an
organ, or a body cavity such as the abdomen, the drugs mainly
affect cancer cells in those areas (regional chemotherapy).
Combination chemotherapy is the use of more than one anticancer
drug. The way the chemotherapy is given depends on the type and
stage of the cancer being treated.
Other
types of treatment that are being tested in clinical trials
include the following:
Biologic therapy
Biologic therapy is a
treatment that uses the patient’s immune system to fight cancer.
Substances made by the body or made in a laboratory are used to
boost, direct, or restore the body’s natural defenses against
cancer. This type of cancer treatment is also called biotherapy
or immunotherapy.
This summary section refers
to specific treatments under study in clinical trials, but it
may not mention every new treatment being studied. Information
about ongoing clinical trials is available from the NCI Web
site.
