Malignant Mesothelioma
Malignant mesothelioma - Cancer tumor that has developed from the
tissue that lines the surface of the chest, abdominal cavity or heart
(pericardium) There are three types of malignant mesothelioma:
epithelioid, which has the best prognosis, sarcomatoid, and mixed type.
Most of mesothelioma occurs in the chest cavity and are called pleural
mesotheliomas. In 10-20% of the tumor develops in the abdominal cavity -
mesothelioma of the peritoneum. Pericardial mesothelioma is very rare.
Exposure to asbestos is the major risk factor for mesothelioma.
The risk of developing mesothelioma depends on the intensity and
duration of exposure to asbestos. Prolonged contact at a young age
greatly increases the risk of mesothelioma. Smoking by itself has no
effect on the increase in the incidence of mesothelioma, but the
combination of smoking and asbestos exposure significantly increases the
risk of lung cancer.
Tumor for a long time may be asymptomatic and therefore often detected
in late stages, which adversely affects the prognosis of the disease.
The median survival of patients is usually only 1-2 years.
Early symptoms of mesothelioma are not specific. These patients
are often ignored or taken for expression of the usual non-neoplastic
diseases. Most patients with mesothelioma symptoms appear within 2-3
months prior to the detection of the tumor.
In some patients the symptoms can persist for 6 months or more. 50% of
patients with pleural mesothelioma noted pain in the chest on the side
or the back. Many patients complain of shortness of breath. In some
cases, there is difficulty swallowing, cough, sweating, weakness, weight
loss and fever. Almost all found pleurisy, fluid in the pleural cavity.
Other symptoms can point to hoarseness, coughing up blood, swelling of the face and upper extremities.
In patients with peritoneal mesothelioma can be abdominal pain, nausea,
vomiting, weight loss. Some patients may receive the fluid in the
abdomen (ascites) and / or swelling.
TREATMENT OF MALIGNANT MESOTHELIOMA
Surgical treatment of mesothelioma
The operation can be performed as a palliative or therapeutic purposes.
Under palliative operation meant surgery, with which you can eliminate
or reduce pain or discomfort caused by tumor growth-plevroektomiya
(removing the pleura), thoracentesis (removal of fluid from the pleural
cavity), etc. Such operations are used when it is impossible to remove
the tumor because of the prevalence of the process or the serious
condition of the patient. Patients in a satisfactory condition, a
localized tumor, radical operations, ie complete removal of
mesothelioma.
Radiotherapy Mesothelioma
External irradiation in patients with mesothelioma is used most often.
With internal radiation radioactive material is supplied directly to the
tumor.
This type of radiation therapy is used as the primary method of
treatment for patients in critical condition, when they can not move a
serious operation. Auxiliary radiation therapy is administered after
nonradical operations to destroy the remaining cancer cells.
Palliative irradiation is used to relieve symptoms caused by tumor
growth: shortness of breath, pain, bleeding and difficulty swallowing.
Mesothelioma Chemotherapy
In the treatment of patients with malignant mesothelioma chemotherapy
drugs can be administered not only intravenously, but intrapleural and
intraperitoneally (into the abdominal cavity).
Depending on the stage of the tumor, chemotherapy may be as basic or
secondary treatment. Moreover, chemotherapy is used only as a
palliative, giving only a temporary effect.
Of anticancer drugs used: doxorubicin, cisplatin, methotrexate, vinorelbine, and others in various combinations.
