What Are The Diagnosis Of Mesothelioma?

Diagnosing mesothelioma is often difficult, because the symptoms are similar to those of a number of other conditions. Diagnosis begins with a review of the patient's medical history, including any history of asbestos exposure. A complete physical examination may be performed, including x-rays of the chest or abdomen and lung function tests. A CT (or CAT) scan or an MRI may also be useful. A CT scan is a series of detailed pictures of areas inside the body created by a computer linked to an x-ray machine. In an MRI, a powerful magnet linked to a computer is used to make detailed pictures of areas inside the body. These pictures are viewed on a monitor and can also be printed.

A biopsy is needed to confirm a diagnosis of mesothelioma. In a biopsy, a surgeon or a medical oncologist (a doctor who specializes in diagnosing and treating cancer) removes a sample of tissue for examination under a microscope by a pathologist. A biopsy may be done in different ways, depending on where the abnormal area is located. If the cancer is in the chest, the doctor may perform a thoracoscopy. In this procedure, the doctor makes a small cut through the chest wall and puts a thin, lighted tube called a thoracoscope into the chest between two ribs. Thoracoscopy allows the doctor to look inside the chest and obtain tissue samples. If the cancer is in the abdomen, the doctor may perform a peritoneoscopy. To obtain tissue for examination, the doctor makes a small opening in the abdomen and inserts a special instrument called a peritoneoscope into the abdominal cavity. If these procedures do not yield enough tissue, more extensive diagnostic surgery may be necessary.

If the diagnosis is mesothelioma, the doctor will want to learn the stage (or extent) of the disease. Staging involves more tests in a careful attempt to find out whether the cancer has spread and, if so, to which parts of the body. Knowing the stage of the disease helps the doctor plan treatment.

Mesothelioma is described as localized if the cancer is found only on the membrane surface where it originated. It is classified as advanced if it has spread beyond the original membrane surface to other parts of the body, such as the lymph nodes, lungs, chest wall, or abdominal organs.

Learn The Symptoms Of Mesothelioma

Do you know that symptoms of mesothelioma may only appear 30 to 50 years after exposure to asbestos? This is very dangerous, however here are the symptoms that we should know:

For Pleural Mesothelioma (These are due to an accumulation of fluid)

• Shortness of breath
  
• Pain in the chest
  

For Peritoneal Mesothelioma

• Weight loss
  
• Abdominal pain
  
• Swelling due to a buildup of fluid in the abdomen.
  
• Bowel obstruction
• Blood clotting abnormalities
• Anemia
• Fever.

If the cancer has spread beyond the mesothelium to other parts of the body, symptoms may include:

• pain
• trouble swallowing
• swelling of the neck or face.

These symptoms may be caused by mesothelioma or by other, less serious conditions. It is important to see a doctor about any of these symptoms. Because only a doctor can make a diagnosis.

Who Are At Risk For Developing Mesothelioma

Asbestos has been mined and used commercially since the late 1800s. Its use greatly increased during World War II. Since the early 1940s, millions of American workers have been exposed to asbestos dust. Initially, the risks associated with asbestos exposure were not known. However, an increased risk of developing mesothelioma was later found among shipyard workers, people who work in asbestos mines and mills, producers of asbestos products, workers in the heating and construction industries, and other tradespeople. Today, the U.S. Occupational Safety and Health Administration (OSHA) sets limits for acceptable levels of asbestos exposure in the workplace. People who work with asbestos wear personal protective equipment to lower their risk of exposure.

The risk of asbestos-related disease increases with heavier exposure to asbestos and longer exposure time. However, some individuals with only brief exposures have developed mesothelioma. On the other hand, not all workers who are heavily exposed develop asbestos-related diseases.

There is some evidence that family members and others living with asbestos workers have an increased risk of developing mesothelioma, and possibly other asbestos-related diseases. This risk may be the result of exposure to asbestos dust brought home on the clothing and hair of asbestos workers. To reduce the chance of exposing family members to asbestos fibers, asbestos workers are usually required to shower and change their clothing before leaving the workplace.

Learn The Major Risk Factors For Mesothelioma

Working with asbestos is the major risk factor for mesothelioma. A history of asbestos exposure at work is reported in about 70 percent to 80 percent of all cases. However, mesothelioma has been reported in some individuals without any known exposure to asbestos.

Asbestos is the name of a group of minerals that occur naturally as masses of strong, flexible fibers that can be separated into thin threads and woven. Asbestos has been widely used in many industrial products, including cement, brake linings, roof shingles, flooring products, textiles, and insulation. If tiny asbestos particles float in the air, especially during the manufacturing process, they may be inhaled or swallowed, and can cause serious health problems. In addition to mesothelioma, exposure to asbestos increases the risk of lung cancer, asbestosis (a noncancerous, chronic lung ailment), and other cancers, such as those of the larynx and kidney.

Smoking does not appear to increase the risk of mesothelioma. However, the combination of smoking and asbestos exposure significantly increases a person's risk of developing cancer of the air passageways in the lung.

What Is Mesothelioma And Where Can It Develops?

First we must know what is Mesothelioma? This is based on the definition given by the National Cancer Institute. Mesothelioma is a rare form of cancer in which malignant (cancerous) cells are found in the mesothelium. Where the cancer gets its name. Most people who develop mesothelioma have worked on jobs where they inhaled asbestos particles.

Moreover, Mesothelium is a membrane that covers and protects most of the internal organs of the body. It is composed of two layers of cells: One layer immediately surrounds the organ; the other forms a sac around it. The mesothelium is responsible in producing a lubricating fluid that is released between these layers, allowing moving organs (such as the beating heart and the expanding and contracting lungs) to glide easily against adjacent structures.

Mesothelioma cancer can develop in the tissues covering the lungs or the abdomen.

Mesothelioma in the chest
The tissues lining (or covering) the lungs are called the pleura. There are two pleura. These can be called pleural membranes. The gap between them is called the pleural space. The pleura are fibrous sheets. They help to protect the lungs. They produce a lubricating fluid that fills the gap between the two pleura. This helps the lungs to move smoothly in the chest when they are inflating and deflating as we breathe.

Mesothelioma is most often diagnosed in the pleura. This is known as pleural mesothelioma. Because it is so close, pleural mesothelioma can also affect the sheet of tissue covering the heart - the pericardium. Doctors call the pericardium the lining, although it is on the outside of the heart. It protects the heart and allows it to move smoothly within the sac that surrounds it. So it does much the same job for the heart as the pleura do for the lungs.

Mesothelioma in the abdomen
The tissue lining the abdomen (tummy) is called the peritoneum. It helps to protect the contents of the abdomen. It also produces a lubricating fluid. This helps the organs to move smoothly inside the abdomen as we move around.

Mesothelioma of the tissues lining the abdominal cavity is known as peritoneal mesothelioma. It is much less common than pleural mesothelioma.

It is unusual for mesothelioma to spread to other parts of the body. But if it does, it does not usually cause troublesome symptoms.

Benign mesothelioma

There is a form of non cancerous (benign) mesothelioma that can develop in the lining of the lungs, or in the lining of the reproductive organs. It can occur in either men or women. These non cancerous tumours are very rare.

Asbestos-Related Diseases

Asbestos is a cancerous material, and exposure to it may result in later development of diseases such as benign pleural effusion, pleural plaques, diffuse pleural thickening, rounded atelectasis, asbestosis, mesothelioma, and lung cancer. Most exposure to asbestos has occurred occupationally. However, people have also been exposed to asbestos through common household products, old buildings, and by indirect contact from loved ones who have work with asbestos directly and have carried home asbestos dust on their clothing.

Although the manufacturing of asbestos products has been greatly reduced in the United States due to increasing governmental regulations since the late 1970's, asbestos still remains present today in old structures, buildings, and even warships that were built before this time. For this reason and due to the long latency period between the initial symptoms of the disease and diagnosis, asbestos-related disease still remains a serious public health hazard.

Asbestosis

Asbestosis is one of many diseases categorized as an “environmental lung disease” or “occupational lung disease”. It is a lung condition referred to as diffuse pulmonary fibrosis. Asbestosis results from coming in contact with asbestos and inhaling its deadly fibers into your lungs. These asbestos fibers, once inhaled, accumulate in the lung tissue, thus distinguishing it from other fibrotic diseases. Additionally, asbestos fibers have been found in small numbers beyond the lungs; such as the tonsils, thoracic and abdominal lymph nodes, pleura, peritoneum, pancreas, spleen, kidneys, liver, stomach, esophagus, small and large intestines. This disease is progressive and irreversible in nature and typically leads to subsequent respiratory disability. In most severe cases, asbestosis may even lead to death from pulmonary hypertension and cardiac failure.

Any accumulation of dust in the lungs, whether is asbestos or not, is referred to as “pneumoconiosis”. Pneumoconiosis also refers to the pathologic response of the human body to the presence of the accumulated dust in the lungs, which results in asbestosis. Some of the symptoms of asbestosis are; shortness of breath, dry cough, X-Ray changes, and pulmonary function deficiencies. The latency period for asbestosis is generally several decades and it can occur in individuals exposed to large amounts of any of the three commercial forms of asbestos (chrysotile, amosite, or crocidolite) for extended periods of time. This disease may also develop even if the exposure was as brief as three years or less, if the level of exposure was heavy. There are also two other types of asbestos, which are non-commercial, and they are amphibole and anthophyllite.

Mesothelioma

The term Mesothelioma is used to describe a cancerous tumor that involves the “mosothelial” cells of an organ, usually the lungs, heart or abdominal organs.

Mesothelioma is classified into two types, pleural and peritoneal. Pleural mesothelioma is the most common type and it is a very rare and aggressive form of lung cancer. The “pleura” is a thin membrane found between the lungs and the chest cavity, which serves as a lubricant to prevent the lungs from chafing against the chest walls. Peritoneal mesothelioma, although less common, is more invasive and therefore results in a shorter life expectancy for the patient. Mesotheliomas have also been found in other abdominal organs.

As with other types of cancer, there are benign and malignant mesothelioma. The most common of the two is by far the diffuse malignant pleural mesothelioma. This particular type of tumor is very aggressive and invasive, spreading quickly over the surface of the lungs, abdominal organs or heart. Depending at which stage this disease is detected and the general health and strength of the patient, the life expectancy for the victims is between four and twenty-four months. The average person diagnosed with this aggressive type of tumor survives for between four and twelve months from the onset of symptoms. These symptoms include cough, shortness of breath, difficulty breathing and sleeping, pain in the chest and abdominal regions, progressive loss of weight and appetite and pleural effusions (fluid in the chest cavity). However, some victims have survived for several years with the proper treatment.

Lung Cancer

Smoking is by far the leading cause of lung cancer. Tobacco smoke causes more than 8 out of 10 cases of lung cancer, according to the American Cancer Society. Tobacco products contain harmful carcinogens (cancer causing agents) that can damage the cells in the lungs. The longer a person has been smoking and the more cigarettes a day smoked, the greater the chances are of contracting lung cancer. Exposure to secondhand tobacco smoke, which is called involuntary or passive smoking, can also increase the risk of developing lung cancer. If a person stops smoking before lung cancer develops, the lung tissue slowly returns to normal.

Even though smoking is mostly responsible for causing lung cancer, it is not the sole cause of it. Asbestos exposure can also cause lung cancer. People who work with asbestos are already in danger of getting lung cancer, and by smoking, the risk is greatly increased. Although the manufacturing of asbestos has slowed down significantly due to government regulations, it is still present in some products and old buildings. However, if left undisturbed, asbestos poses no danger. Asbestos is only dangerous when it has been disturbed and its raw form (fibers) is released into the air and breathed in.

What Is Asbestos?

The term asbestos comes from the Greek word for “inextinguishable” or “indestructible.” Asbestos is a fibrous mineral with thermal and chemical resistance, flexibility, and high tensile strength properties. Although its use has been reduced since the 1970's, today asbestos is still present in many common household items and old buildings.

The first use of asbestos dates back to 2500 B.C., when it was used as a wick material for oil lamps and also in pottery making. Asbestos was also used in cloths for retaining the ashes of the dead during cremation. Mats were also made from asbestos by both the Chinese and Egyptians. Combining asbestos with clay and other materials was also one of its earlier applications.

Asbestos is classified into many different types, which include; chrysotile (white asbestos), crocidolite (blue asbestos), amosite (brown asbestos), tremolite, anthopyllite, and actinolite.

However, only chrysolite is the most widely used asbestos type in the United States. Other asbestos types used commercially are crocidolite and amosite, but in a limited capacity. Tremolite, anthopyllite, and actinolite are the most abundant, but they have been used primarily as contaminants of other minerals, such as chrysotile, verniculite, and talc.

Since its discovery, asbestos has found widespread use in part due to its unmatched engineering and commercial performance. Due to its thermal resistant qualities, asbestos has been used as a frictional material in break pads. It has also been used in specialized products such as gaskets, pads, fabric sheets, and asbestos paper due to the length and pliability of its fibers. Mixed into a slurry, asbestos has been applied to building surfaces for fire protection and heat retention, such as in furnaces and kilns. As a fortifying additive, which is it's major present day use, asbestos is a component of cement, concrete, paint, vinyl, and tar mixtures, accounting for 70% of current applications worldwide.

Informed Consent for Treatment of Mesothelioma Cancer

Informed Consent is the term used to describe the communication between health providers and patients, particularly in clinical trials for new treatments. Informed Consent laws vary greatly from state to state, and also according to the specific case. In many states, Informed Consent laws may be more stringent in cases that involve experimental treatment. Additionally, some informed consent laws require written documents, while others do not.

Most laws require that patients be physically and mentally capable of understanding their condition and the ramifications of the proposed treatment. Therefore, in cases where the patient is unable to give their consent, the legal guardian of the patient makes treatment decisions for the patient. In the case of minors, parents are involved in any Informed Consent issues.

The primary purpose of informed consent is for the patient to have a complete understanding of their treatment, the possible risks of treatment, and the long term consequences of treatment. The goal is for the patient to have reasonable expectations of the effectiveness of treatment, and to understand any possible limitations there may be. As with nearly all cancer treatments, there are usually significant side effects that must be discussed and understood, as there may be instances where patients may find possible side effects too severe when compared to the potential benefits.

Costs associated with treatment are also a major factor when considering possible treatments. Some patients may need time to determine the financial impact. Additionally, the treatment itself may have logistical issues that the patient might want to consider. Certain treatments may be too draining for some malignant mesothelioma patients, who may prefer to spend their time and energy with friends and family.

With Informed Consent, patients are given alternative treatment options as well, helping to give them a full perspective on their available options. Although offering alternative options is a part of Informed Consent, many doctors encourage patients to independently research and explore all their options. Informed Consent does not stop after the initial pre-treatment dialogue. The process of Informed Consent is ongoing, which is essential because patients may change their feelings about a treatment during the clinical trial. These trials are highly regulated, including by the FDA, which has many regulations applicable to trials regardless of whether they have received federal funding. Additionally, many hospitals have Institutional Review Boards that monitor and regulate the clinical trials conducted under their supervision. Clinical trials may also be subjected to peer reviews prior to patient trials. All of these measures are part of the Consent process, and help ensure that the trials run smoothly and safely.
