Surgery for mesothelioma may be done for 1 of 2 reasons: to
try to cure the cancer or to relieve (palliate) pain and other symptoms
caused by the tumor.
Potentially curative surgery
Potentially curative surgery may be an option if you are in
otherwise good health and the tumor is thought to be localized and can
be removed completely. Unfortunately, mesothelioma cells tend to spread
into the chest wall, around the heart, over nerves, and the diaphragm.
It is often difficult to detect this spread and remove these cells.
Because of this, not all doctors agree on the exact role of surgery. In
most cases it is not likely to cure you but may extend your life.
Still, potentially curative surgery is being done in some major cancer
centers, and a few patients who have had the surgery have had long
remissions of their disease.
Two surgical procedures may be options if you have pleural
mesothelioma:
Extrapleural
pneumonectomy: This is an extensive operation that
attempts to remove all or most of the cancer and some surrounding
tissues as well. It is most often used in patients with localized
mesothelioma of the epithelioid type, when the surgeon thinks a cure is
possible. The operation removes the pleura lining the chest wall,
diaphragm, and pericardium, as well as the whole lung on the side of
the tumor. The diaphragm and the pericardium are then reconstructed
with man-made materials. This is a difficult operation and is done only
by surgeons in large medical centers. You must be in good overall
health with good lung function and no other serious illnesses to
tolerate this surgery. Major complications occur in as many as 1 in 4
people who have this operation.
Pleurectomy/decortication:
Pleurectomy/decortication is a less extensive operation.
This procedure removes the pleura, where the majority of the tumor is
located. While it may be used to try to cure some cancers, it is more
often used as a palliative procedure to relieve symptoms in cases where
the entire tumor cannot be removed. It can help control the buildup of
fluid, improve breathing, and decrease pain caused by the cancer.
Palliative surgery
Palliative surgery may be an option if the tumor has already
spread beyond the mesothelium and is difficult to remove completely, or
if you are too ill for a more extensive operation. The goal of this
surgery is to relieve or prevent symptoms, as opposed to trying to cure
the cancer.
For pleural mesotheliomas, pleurectomy/decortication
(described above) is the most common type of palliative surgery. But in
many cases, even this surgery may be too much for a patient to
tolerate.
Surgical treatment of peritoneal mesothelioma is often done
either to help relieve symptoms or to remove the tumor from the wall of
the abdomen and other digestive organs. As with pleural mesothelioma,
these tumors are often too extensive to remove completely. Similar
operations can be done to remove a mesothelioma from the pericardium
(the sac around the heart).
Surgery for mesothelioma of the tunica vaginalis testis, which
occurs in the groin, is also not usually curative. Most of the time
surgery is done because the tumor resembles a hernia. The surgeon
attempts to treat a suspected hernia and only realizes the diagnosis
after the surgery is begun. This kind of mesothelioma typically can't
be removed entirely.
Other palliative procedures
Several less invasive procedures can be used to control some
of the symptoms caused by mesotheliomas, especially those due to the
buildup of fluid.
Thoracentesis/paracentesis/pericardiocentesis:
In these procedures, a doctor uses a long, hollow needle to remove
excess fluid from a body cavity. While they are described in the
section, "How
is malignant mesothelioma diagnosed?", they can be done to
provide relief from symptoms caused by fluid buildup, such as shortness
of breath. The major drawback with these techniques is that they often
need to be repeated.
Pleurodesis:
This procedure may be done to try to prevent fluid from building up in
the chest cavity. A small cut is made in the skin of chest wall, and a
hollow tube is placed into the chest to remove the fluid. Either talc
or a drug such as doxycycline or a chemotherapy drug is then instilled
into the chest cavity. This causes the linings of the lung (visceral
pleura) and chest wall (parietal pleural) to stick together, sealing
the space and preventing further fluid buildup. The tube is generally
left in for a day or two to drain any new fluid that might accumulate.
Shunt placement:
This approach may be used if pleurodesis or other
techniques are not effective. A shunt is a device that enables fluid to
move from one part of the body to another. For example, a
pleuro-peritoneal shunt allows fluid in the chest to move into the
abdomen, where it is more likely to be absorbed by the body. The shunt
is a long, thin, flexible tube with a small pump in the middle. In the
operating room, the doctor inserts one end of the shunt into the chest
cavity and the other end into the peritoneum. (The pump is placed just
under the skin over the ribs.) Once the shunt is in place, the patient
uses the pump several times a day to move the fluid from the chest to
the abdomen.
Catheter
placement: This is another approach sometimes used to
control the buildup of fluid. One end of the catheter (a thin, flexible
tube) is placed in the chest or abdomen and the other end is left
outside the body. This is done in a doctor's office or hospital. Once
in place, the catheter can be attached to a special bottle or other
device to drain out the fluid on a regular basis.
