MESOTHELIOMA TREATMENT OPTIONS
 While there is currently no known cure for
malignant mesothelioma, treatments are available with the most common being
surgery, chemotherapy and radiation therapy.
Your doctor will recommend one treatment or a
combination of therapies that are best for your situation. The course of
treatment will depend on a number of factors including the location of the
disease, the stage of the disease, your age, overall health and your
preferences.

Traditional Treatment Options
There are three traditional kinds of treatment for patients with malignant
mesothelioma:
Doctors will often use two or more of these
treatment courses jointly to provide the maximum likelihood of success. This
“multi-modal” approach holds the most promise for survival of malignant mesothelioma patients. Trimodality therapy, in which all three of these
modalities are used, is considered the most effective, and aggressive, approach.
Surgery
There are several types of surgeries used to
treat mesothelioma and the disease type and stage will determine the type of
surgery. Mesothelioma tumors are usually large and difficult to completely
remove, so surgery is usually combined with other cancer treatments to ensure
the best results in destroying the tumor.
There are generally two types of surgical methods for the treatment of
mesothelioma: Palliative Procedures and Potentially Curative Procedures.
-
Palliative Procedures are those which treat
the symptoms of mesothelioma, providing relief for the patient, without
aggressively treating the disease itself.
Chest Tube Drainage and Pleurodesis
The goal of chemical pleurodesis is to cause an irritation between the two
layers covering the lung. This irritation causes an obliteration of the space
between the layers where the fluid accumulated, and prevents further fluid to
be able to accumulate there. There are a variety of agents, which can be used
including talc and bleomycin. As the pleural space is closed, fluid drains out
of the chest cavity using a chest tube.
Pleuroperitoneal Shunt
Pleuroperitoneal shunting has been used in patients who have failed chemical
pleurodesis, chemotherapy, or radiation therapy. Pleuroperitoneal shunting can
provide effective palliation in patients with a trapped lung or others who
have failed treatment.
-
Potentially Curative Options are medical
procedures that attempt to remove all gross disease with 'curative intent'.
Residual microscopic disease cells are then removed through
Adjuvant therapy.
Pleurectomy/Decortication
A Pleurectomy/Decortication is a surgical procedure where the pleura, the
membrane lining the lungs and chest cavity, is removed, without removing the
entire lung. This treatment option is usually performed on patients in the
early staging of mesothelioma.
Extra-Pleural Pneumonectomy (EPP)
EPP is the
removal of the pleura, diaphragm, pericardium, and the whole lung involved with
the tumor. EPP is considered a radical therapy and is not frequently performed
by most surgeons,
patients are referred to centers specializing in
these treatments.
Both the above 'potentially curative' procedures are typically used in
combination with other treatment options
(multi-modal therapy).
Chemotherapy
Chemotherapy uses drugs to kill cancer cells and may be used as the primary
treatment to mesothelioma, or it may be used as part of a multi-modal approach.
Chemotherapy is referred to as systemic treatment because the drug is introduced
into the patient’s bloodstream and travels throughout the body killing cancer
cells. The drugs may be in pill form, or injected into the body through a
needle.
In addition to killing cancer cells, chemotherapy drugs work to restrict the
uncontrolled spread of abnormal cancer cells - preventing them from dividing and
multiplying.
Chemotherapy is not considered a 'curative' approach for the treatment of
mesothelioma and instead focuses on shrinking existing tumors (usually prior to
surgery - neoadjuvant therapy), controlling the spread of the cancerous cells,
and removing residual cancer cells following surgery (adjuvant therapy).
To
effectively treat mesothelioma, more than one drug may be used in chemotherapy. Depending on the
drugs, the amount taken and the treatment period, there may be side effects.
Historically, doxorubicin has been the most widely used single chemotherapy
drug. Other newer drugs, including gemcitabine, cisplatin, carboplatin,
epirubicin, cyclophosphamide, ifosfamide, vinorelbine, paclitaxel, and
methotrexate, now are often preferred and are usually given in different
combinations.
Radiation Therapy
Radiation therapy uses high-energy x-rays help to destroy cancer cells and
shrink tumors. The radiation may come from outside the body from a machine
(external radiation) or from radioactive materials placed directly in or around
cancer cells through thin plastic tubes (internal or implant radiation).
In pleural mesothelioma, it is difficult to
irradiate tumor tissue successfully without injuring nearby organs like the
lungs, heart, and liver. However, radiation therapy can be very effective in
relieving pain in certain situations. Factors which can impact the use of
radiation treatment include the volume of the tumor and how near it is to vital
organs.
Non-Traditional Treatments
Photodynamic Therapy
Photodynamic therapy destroys cancer cells by using the energy from light
and may also be effective when combined with surgery. Although this treatment is
in the experimental stage for mesothelioma, it has shown promising results in
treating other cancers. In the procedure, the patient receives a photosensitizer
(a drug which makes cells sensitive to specific wavelengths of light) which
collects in cancerous cells but not in healthy cells. Once the cells have been
sensitized, fiber optic cables are placed in the body (usually through
open-chest surgery) so that the correct frequency of light can be focused on the
tumor. This causes the photosensitizer drug to produce a toxic oxygen molecule
which kills the cancer cell.
Gene Therapy
This is a new treatment, currently in clinical trails. This approach allows
treatment to target tumors, rather than destroying healthy cells which is the
negative of traditional chemotherapy. In gene therapy, cancer is treated by
altering genetic defects that allow a tumor to develop. A “suicide gene” is
inserted directly into the tumor, making the cells sensitive to a normally
ineffectual drug. The drug is then administered to the newly sensitive cancer
cells and it destroys those cells while leaving the healthy cells unharmed.
Immunotherapy
Immunotherapy (or biological therapy) treats cancer by using the body’s own
immune system fight cancer cells. Another name often applies to this therapy,
biological response modifiers (BRMs). Though not yet obtainable, promising
clinical studies are underway for immunotherapy.
