Asbestos And Mesothelioma

Mesothelioma is a malignant tumor of the mesothelium caused by exposure to asbestos fibers. There is some important information one should be aware of if he is considering pursuing an asbestos mesothelioma lawsuit. Prior to pursuing a lawsuit, he should seek advice from a reputable mesothelioma lawyer for a better understanding of mesothelioma law. A mesothelioma lawsuit can also provide one with adequate compensation that will help cover his legal, medical, and ongoing expenses related to the mesothelioma cancer.

Previously, due to exposure to an asbestos related substance, there have been cases in which the mesothelioma cancer sufferers have received thousands of dollars in compensation for their diagnosis of mesothelioma. Recently, mesothelioma lawsuits help the person who has developed with mesothelioma by providing various benefits. Lawsuits have included people who have been exposed to asbestos related substances through their work environment, and companies are required to compensate their present or previous employees for non-disclosure of the risks involved with handling asbestos and related substances.

Mesothelioma law works on the premise that this exposure to an asbestos or related substance without prior knowledge has lead to the injury, and sometimes death of the asbestos mesothelioma sufferer. Beginning your lawsuit early will ensure that you acquire adequate compensation in time to help with your medical expenses and ongoing support and treatment. In order to begin a lawsuit, you will need to find an experienced mesothelioma attorney or lawyer, and they can usually be found at reputable law firms.

It is important that you disclose all information surrounding your asbestos mesothelioma cancer, including your diagnosis and prognosis to your mesothelioma attorney or lawyer, as this will help him to form a solid lawsuit for your case.

You should also try to provide your attorney or lawyer with details pertaining to the period in which your exposure occurred, who you were working for at the time, and any details regarding whether you had prior knowledge of your exposure. All this information is considered to be important and will ensure that your mesothelioma attorney or lawyer will be successful in your mesothelioma lawsuit. One is always recommended to seek legal assistance as soon as the person has diagnosed with mesothelioma.

The treatment of mesothelioma is done using various options all of which aim at the removing or suppressing of the malignant mesotheloima cells. Modern improvements have occurred in the treatment of the disease. These have mainly been in prognosis into newer chemotherapies coupled by multimodality treatments. It is important to note that treatment of the malignant cells at an early stage is essential since this enhances better prognosis. However, cure for this cancer is usually rare. The malignant cells have certain clinical behaviors which affects the malignancy. These factors range from the continuous mesothelial surface which favors local metastasis through exfoliated cells, invasion of other cells hence the random growth within the underlying tissues and the period between exposure to asbestos and disease development. There are three important factors to be considered in the disease prognosis which include:the age of the patient, health status,and the histological subtype. The epithelioid responds better to treatment and has a higher survival rate as opposed to the sarcomatoid histology.

The treatment options present include:

Surgery

This is mainly used where mesothelial cancerous cells are present. They may lead to the formation of growth which are surgically removed through excision. It is not effective if used alone but can be combined with other procedures for example chemotherapy in order to improve the median survival rate. The most common procedure in operation is pleurectomy which involves the removal of the chest’s lining. Extrapleural pneumonectomy is the lesser common where the lungs, chest lining, pericardium and the hemi-diaphragm are removed.

Radiation

It is given before the operation as a consolidative treatment. This is often to patients who can withstand radical surgery and have localized disease. Radiation therapy is conducted hand to hand with chemotherapy and when done after surgery may lead to an extended life expectancy in different patients of up to 5 years. It is commonly applied to the chest drain insertion area to restrict track tumor growth along the chest wall. This is a curative approach an dis now commonly used in treatment.

Immunotherapy

This treatment option has yielded mixed results in the cure of mesothelioma. Some of the cells are susceptible to in vitro lysis of LAK cells but patients under this treatment have had massive side effects. Therapy through the use of interferon alpha are more encouraging since it has led to 50% tumor mass reduction in 20% of the patients with few side effects.

Heated Intraoperative Intraperitoneal Chemotherapy

Here, the surgeon removes much of the tumor and then a chemotherapy agent is directly applied. This agent is heated at temperatures of 40 and 80 0c in the abdomen and is perfused for between 1 and 2 hours then drained. Heating increases the drug penetration into tissues and also destroys the malignant cells more than the normal cells. This procedure allows one to administer high drug concentrations into the affected surfaces.

Multimodality Therapy

This technique was developed on the need to reduce the bulk of the tumor and hence improve survival of the patient. Both extrapleural pneumonectomy and pleurectomy are used and the indications of their use are unique. Size of the tumor influences the choice of operation. In the former, the underlying lung is spared and is performed on patients within the early stage. Here the intention are to remove the whole tumor as opposed to extrapleural pneumonectomy which is more extensive. It is performed on patients whose tumors are more developed and can not tolerate pneumonectomy.

Mesothelioma cancer is a type of cancer that attacks the lungs and chest cavity. Also known as asbestos lung cancer, it forms deadly tumors where mesothelial cancer cells form a protective lining over the lungs, heart, and abdominal organs. It is a type of lung cancer that takes many years to develop and produce symptoms. Roughly 3,000 cases per year (mostly men over the age of 40) are reported. It is estimated that number will grow to about 300,000 cases before 2030.

Types of Mesothelioma Asbestos Cancer

Epithelial mesothelioma is a rare and fatal form of cancer affecting the membrane lining of the chest cavity, heart, lungs, and abdominal cavity. There are three forms of epithelial mesothelioma: the most common is Pleural Mesothelioma, the second most common, Peritoneal Mesothelioma (accounting for only a quarter of the cases), and the rarest form, pericardial mesothelioma.

Pleural mesothelioma, the most common type of this disease involves the pleura, a thin membrane located between the lungs and the chest cavity. The pleura provide a lubricated surface so that the lungs do not rub and chafe against the chest walls. There are two types of pleural mesothelioma the first being ‘diffuse and malignant’. This type is cancerous and is generally fatal within a year of diagnosis. The second type is ‘localized and benign’ and is generally non-life threatening. It can usually be removed through surgery.

Lung Lining cancer is not to be confused with lung cancer. In lung lining cancer, the effected area of the body is called the mesothelium, a thin membrane that covers many of the internal organs of the body. The mesothelium of the lungs is called the pleura. Lung Lining cancer is also sometimes called mesothelioma after the area in which it occurs.

This thin membrane is comprised of two layers – one that surrounds the organ and another that forms an exterior sac around the first layer. Between the layers of the mesothelium is a fluid that allows vital organs to glide easily against objects that come in contact with them.

Localized pleural mesothelioma is not always caused by asbestos exposure. However, if it has spread to other parts of the body, for instance the lymph nodes, lungs, chest wall, or abdominal organs, then it is considered malignant and is more often than not the result of asbestos exposure.

Peritoneal mesothelioma appears as a tumor in the peritoneum membrane of the abdomen. This type of mesothelioma is very rare, comprising less than a fourth of all known cases of the disease. There are no effective treatments for this condition, and most patients live less than a year after diagnosis.

Mesentery cancer is likened to peritoneal cancer (mesothelioma). This cancer primarily affects the sections of the peritoneum that attach different organs to the wall of the abdominal cavity, (i.e. mesogastrium for the stomach, mesojejunum for the jejunum). Mesentery cancer includes all abdominal peritoneal extensions. Tumors rarely originate in the actual mesentery, though it is a frequent route for the spread of mesothelioma through the abdominal cavity.

Pericardial mesothelioma is the rarest form of mesothelioma, affecting the membrane around the heart (called the pericardium or pericardial sac). In this disease, solid masses and effusion (fluid) develop around the pericardium. Not all effusions are strictly related to mesothelioma.

The Causes

Mesothelioma cancer is caused by exposure to asbestos fibers or dust. Workers in the asbestos industry are prime targets for attracting this deadly disease. Asbestos fibers enter the body, either by breathing in the tiny asbestos fibers or by swallowing them. The fibers cause healthy cells to mutate into cancer. Since the body is unable to dispel these fibers, the lungs become inflamed (asbestosis). This condition worsens and eventually becomes malignant. Asbestos exposure is thought to be responsible for roughly 75% of all cases of lung lining cancer.

Symptoms

Mesothelioma is a very difficult cancer to detect in early stages. The early symptoms tend to be generic and even nonexistent in some cases, and it can take as much as 15 to 50 years after exposure to develop. The first symptom is often constant chest pain, followed by coughing, lung damage, and shortness of breath. Patients who have peritoneal mesothelioma (a less common form of mesothelioma) generally experience abdominal pain, loss of appetite, nausea, and abdominal swelling, often in addition to the symptoms of pleural mesothelioma. They may also develop bowel obstruction or further breathing obstruction.

Stages and Diagnosis of Mesothelioma

There are three staging systems used to determine treatment for mesothelioma: Butchart System, TNM System, and the Brigham System

Butchart Staging System

The Butchart System is the oldest system and the most common. This system concentrates upon determining the extent of primary tumor mass and divides mesothelioma into four stages.

Stage I of the Butchart System consists of the presence of mesothelioma in the lining of the right or left lung and may also involve the diaphragm on the same side. Stage II includes the progression of mesothelioma into the chest wall, esophagus, or lung lining on bother sides. There may also be lymph nodes in the chest. The onset of Stage III begins when the mesothelioma surpasses the diaphragm into the lining of the abdominal cavity or peritoneum. In this stage the cancer may also affect the lymph nodes extending beyond those in the chest. Doctors identify Stage IV, the final stage, when evidence of the spread of cancer to other organs (metastasis) is confirmed.

TNM System

Stage I of the TNM System involves the lining of the right or left lung, pericardium, or diaphragm on the same side. At this stage, lymph nodes are not involved. Stage II begins when mesothelioma spreads from the lining of the lung on one side to a lymph node on the same side. At this stage, the cancer may also spread to the lung, pericardium, or diaphragm on the same side. Stage III begins when mesothelioma is present in the chest wall, muscle, ribs, heart, esophagus, or other organs in the chest on the same side as the primary tumor. In the final stage, Stage IV, the mesothelioma has travelled into the lymph nodes in the chest on the side opposite the primary tumor, into the lung opposite the primary tumor, or directly into the organs in the abdominal cavity or neck. Metastasis is the final result in this stage.

Brigham System

The Brigham System determines the resectability (the ability to surgically remove) the mesothelioma mass. In Stage I the tumor is resectable, while lymph nodes remain unaffected. In Stage II the tumor remains respectable but the mesothelioma affects the lymph nodes. In Stage III the tumor becomes unresectable. It has penetrated through the diaphragm, or peritoneum. Stage III can occur with or without lymph involvement and extends into the chest wall and heart. Stage IV occurs when doctors discover metastatic disease involving distant organs.

After doctors identify the stage of a patient’s malignant mesothelioma, the patient and doctor consider the various treatment options available. Mesothelioma treatment programs are contingent upon many factors, including the stage of the cancer, the location of the cancer, the spread of mesothelioma cancer, the characteristics of the cancer cells under a microscope and the patient’s age and concerns.
