How Is Mesothelioma Diagnosed?

by Ivan Chia

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.

Medical mesothelioma diagnosis

Medical thoracoscopy in the diagnosis of unexplained pleural effusion.

Respirology 1998 Jun;3(2):77-80

Wilsher ML, Veale AG

Respiratory Services, Green Lane Hospital, Auckland, New Zealand.

Approximately 20% of pleural effusions remain without an established aetiology after evaluation. Thoracoscopy has a very high sensitivity for the diagnosis of both benign and malignant diseases and greatly increases the diagnostic yield for pleural effusion. We sought to evaluate the diagnostic yield and safety of medical thoracoscopy at this institution.

The records of all patients undergoing medical thoracoscopy for the evaluation of undiagnosed pleural effusion between 1990 and 1996 were reviewed. The procedure was performed under local anaesthesia with sedation using a Stortz rigid thoracoscope. Fifty-eight patients had thoracoscopy, most having had two (range: 1-6) non-diagnostic pleural aspirations and biopsies of the pleura. Nineteen patients were found to have mesothelioma and nine metastatic malignancy. Three patients were considered likely to have tuberculous pleural disease, six had asbestos related benign pleural fibrosis and three post-cardiotomy syndrome.

There was one chylous effusion of uncertain aetiology, one posttraumatic and two other benign effusions, both of which resolved without clear aetiology. On seven occasions the pleural space could not be adequately accessed, but none of these patients had prior computerized tomography (CT) or ultrasound of the pleural space. There were five false negative diagnoses of malignancy, but no false positives.

The diagnostic sensitivity for pleural malignancy was 85% and specificity 100%. There were no major complications, but four patients had late tumour seeding at the thoracoscopy site. Medical thoracoscopy is a safe procedure with a high diagnostic yield. Pre-operative evaluation of the pleural collection using ultrasound or CT increases the likelihood of successful access to the pleural space and may increase diagnostic yield.

Mesothelioma. Like the doctors in diagnosing cancer asbestos? Part 2

Continued from Part 1

If the suspect is Erguß for certain infections or cancer, a sample of the liquid, the idea of whether benign or malignant. However, four of the five tests can be less cancer. Finally, the biopsy of the pleura with a needle or by an operation confirms the diagnosis of Mesothelioms.

For the abdominal mesothelioma, an abdominal X-ray checked the liquid in your stomach.

Sometimes an X-ray show not only the martyrdom, but also the mass, or the collection of signs, asbestos, plates and pleurales calcifications or scar by asbestosis and chronic inflammation.

Drain the liquid from needles in the chest or abdominal cavity. The name is thoracocentesis vacuuming or pleural fibrosis of the breast, and abdoparacentesis peritoneal aspiration or in the abdomen.

In modern days, CT (computer tomography) scan is more frequently. CT is a device, the X-ray image shows images of the slices of your body. Tomodensitométrie the chest or the abdomen shows the swelling of organs, which caries, and the lymph nodes. A contrast ratio of tincture can help to the analysis. Tomodensitogrammes show pleural effusion, pleural effusion thickening, pleural fibrosis calcification, the spread of the tumor in the chest wall. But CT is not really distinguish the benign disease that asbestos, lung cancer and mesothelioma. The doctors have also lead to action, for the computed tomography, the needle desire of the masses suspicious pleural mesothelioma.

Thoracoscopie is the procedure when a surgeon makes small notch in the chest wall between the two coasts and looks through a thoracoscope (a tool with a video camera). The biopsy (tissue sample) is in a laboratory to the cancer cells.

Bronchoscopy, the physician may look into the airway. A thin flexible hose (bronchoscope) allows samples of tissues and sent to a laboratory for the testing of cancer cells.

Médiastinoscopie controls funds coat (the zone with heart in the chest, large blood vessels, lymph nodes, esophagus, nerve, etc.). Médiastinoscopie allows for the removal of the lymph nodes in the body after the metastases.

The Laparoscopy is a surgical procedure where doctors look in your stomach with a small camera with a hose. The surgeons are biopsy suspicious areas. The bioptate (the sample of the tissue) in the laboratory. A doctor under the microscope. Laparoscopy can be a small cut in the skin of your abdomen. Another name for the same procedure is peritoneoscopy. The tool is peritoneoscope appointed.

A needle in the abdomen area and removal of liquids in the name paracentesis a needle in your chest to drain the fluid and will thoracentèse.

The MRI (magnetic resonance imaging) scan is a photo cut out of your body. That is better than X-ray or computed tomography, as there is no radiation in your body. But it requires a lot of time. It may take up to 20 minutes. And some people are afraid to stay in the machine for half an hour for the exam. In addition to the MRT has a limit. The test requires avoid metals in your body (such as seals made of metal and other metallic implants). The IRM is not a test program, so sometimes it is not ordered. Magnetic resonance imaging is commonly arranged in order to determine the extent of the tumor in the area of surgery. The MRI also easier than CT shows swelling of the lymph nodes and the surface of the membrane, and it is important for the planning of surgery.

Positron emission tomography (PET) recently came for the diagnosis of various types of cancer and mesothelioma so. PET uses of radioactive materials, which emits positrons. City mesothelioma is on the pleura. Advanced mesothelioma in the lungs, the wall of the chest, abdomen and lymph nodes.

Pathology examination of the samples under a microscope reviewed biopsy It is difficult to diagnose mesothelioma sometime. The cells of the tumor are different species. These cells can be like other types of cancer. Péritonéale cells as pleural mesothelioma, or other types of lung cancer and ovarian cancer. Epithelioid kind mesothelioma is more frequent and better, for longer than an aggressive type sarcomateuse. Biphasique that mesothelioma is a mixture of the two.

The doctors and scientists have proposed a number of immunological decision-makers to find mesothelioma, but the majority of the markers are not very precise. Just to signal: Epithelial membrane antigen, the CEA (carcino-antigen √ very inaccurate, it can in many cancers), Calretinin, Mesothelin, Cytokératine, ostéopontine and some others.

So, to summarize, the tests carried out by the doctors:

* X-Rays

* Tomodensitométrie

* Thoracocentesis

* Paracentesis

* Thoracoscopy

* Bronchoscopy

* IRM

* Media-Tino’s Copy

* Laparoscopy

* All types of biopsy

The diagnosis is made after a careful evaluation of symptoms, physical examination and imaging in the biopsy.

A brief overview of mesothelioma

Introduction

Today there is much discussion in the world, both offline and on the Internet, via the mesothelioma. In the United States, there are groups awareness mesothelioma in almost every city in the United States. In addition to the discussion forums, legal mesothelioma cells, mesothelioma forums, groups, etc. awareness mesothelioma, mesothelioma, which today is a very broad topic. There is even a mesothelioma Memorial Scholarship, it is proposed that each quarter. The scholarship is in memory and honor, those who were affected, by mesothelioma. Billions of dollars have been spent to try to make the fight against this terrible disease and a cure to be found. Let us begin, ask this simple question - what is that mesothelioma?

What is mesothelioma?

Asbestos and mesothelioma infâmant are bound. The Mesothelioma is a form of cancer affects people who were exposed to asbestos. It is a rare form of cancer, and touched that the people who have a story created by asbestos, others not. However, it may be secondary, in which a person can be in touch with someone who was asbestos in the past. The key for mesothelioma, as well as here, is the risk from asbestos.

The main cause of mesothelioma is an asbestos exposure. Once the patient inhaled asbestos dust / fibres, other factors such as smoking, the situation in a period of time. It may also have other causes mesothelioma. For example, there were cases in which patients diagnosed had no history of asbestos exposure. People can use it to the people, that the asbestos exposure. Before proceeding, define mesothelioma.

Mésothéliome Definition: The mesothelioma is defined as a rare form of cancer, often in connection with a previous exposure to asbestos. In this disease, malignant (cancer) in the cells of the mésothélium develop protective fairing, the majority of the organs of the body. Mésothéliome malignant cells proliferate in the affected area, and are usually very difficult to reduce.

The mesothelioma has come to be widely known, only about 60 years old, if the symptoms have begun to manifest, and the cases of mesothelioma diagnosed. Across America, for the people who are in institutions, in connection with asbestos, it is a nightmare. It was more because at the time, asbestos, because of the many advantages that other metals, was often in all industries around the world. It was a tragedy, the epic proportions, which is expected to be triggered when it was triggered, he devastated the lives of people everywhere in America. Thousands lost their lives for the mesothelioma, and even today, thousands of others remain in the fight against this terrible disease.

Even today, more than 3000 people will receive a diagnosis of mesothelioma in the United States. Today, the mesothelioma victims and their families struggling to cope with the disease. For the survivors mesothelioma court action against the industries in which the disease on them was a exorciser through the pain and suffering that they had to suffer. For a number of victims of mesothelioma lawyers were in a position to the business with success. There are groups of mesothelioma mesothelioma support for the victims and their families for life, resulting from the disease. There are websites, like www.mesotheliomaweb.org, www.mesothelioma.com, www.cancer.gov, etc.

The mesothelioma is extremely violent, for several reasons:

• The mesothelioma diagnosis is often very late. It shows itself in a person after years of asbestos exposure, so long, that 15 to 20 years ago.
• During the period of pregnancy is very long, it is as mentioned above, the time of the exhibition is very short, less than two to three months. This means that the person is not even necessary, for a longer exposure.
• The average life of a person, after diagnosis, is very short, about 24 months.
• It is not just a person who is exposed to asbestos, the chances that it is possible, are you in the dust or asbestos fibers also expensive.

Types mesothelioma

Mainly, the mesothelioma is divided into three areas on the basis of mesothelioma is divided into two categories:

• pleural fibrosis mesothelioma (pleural mesothelioma, the exterior coating protects the chest cavity and the lung)
• pericardial mesothelioma (Pericardium of mesothelioma, the bag surrounds the heart)
• peritoneal mesothelioma (mesothelioma of the peritoneum, the wall to protect the abdominal cavity)

Based on the types of cells, in a mesothelioma patients who have mesothelioma can into 3 types:

• Epithelioid mesothelioma (about 50 to 70 percent of all cells mésothéliales)
• Sarcomatoid mesothelioma (less commonly mesothelioma cell type, about 10 to 15 percent)
• Biphasic mesothelioma. (Approximately 20 to 40 percent of all cells mésothéliales)

The symptoms of mesothelioma

The symptoms of Mesothelioms depends on the type of Mesothelioms a patient can have. If a patient with a malignant pleural mesothelioma, usually feel pain in the chest, accompanied by shallow breathing. These symptoms occur because of the submission of fluid in the pleura.

Mésothéliome peritoneal symptoms differ from those of pleural mesothelioma. In the case of peritoneal mesothelioma found, the symptoms are:

• Fever
• difficulties in the chair
• Anemia
• The abnormalities in the course of blood clots

In the case of peritoneal mesothelioma, the symptoms include pain, swelling of the face or the neck, and the difficulties of absorption.

Mésothéliome card symptoms of other, less serious inconvenience. Therefore, it is advisable to consult a doctor to ensure that the symptoms show.

The diagnosis of Mesothelioms

Mésothéliome diagnosis is not an easy task, because the symptoms of the card to a lesser other diseases, as already mentioned above. The first step for the diagnosis of mesothelioma is a journal in the history of medicine to the patient. It is important to know whether the patient has a disease whose symptoms shows to mesothelioma. At this point, it is also important to know whether the patient previously asbestos. If the patient is not disease, the symptoms associated with mesothelioma, and had an asbestos exposure, then it may be suspected mesothelioma.

It is important to have a physical examination of patients, including X-ray, magnetic resonance and tomodensitogrammes. The focus is usually on the regions of abdominal and chest. If there is something suspect after conclusion of the investigations, it is advisable to a biopsy.

A biopsy is usually by a specialist or a surgeon or oncologist. Biopsy is a sample of tissue of the patients and to undergo tests to determine the presence or absence of mesothelioma. Biopsy with mesothelioma:

• Thoracoscopy (by the taking of samples of tissue inside the breast, with a thoracoscope)
• Peritoneoscopy (by the taking of samples of tissue from the abdomen, with a peritoneoscope)

Once the diagnosis, it is necessary to know which step mesothelioma was found. Depending on whether the cancer is still in its original position, or, if they stick to the other parts of the body, which can be called mesothelioma:

• City (still in its original location)
• Advanced (spreading to other parts of the body)

Treatment of Mesothelioms

Mésothéliome treatments according to mesothelioma, as in the phase where it is found. The three treatments, the most common forms of the Mesothelioms are:

• Surgery - Surgically abolition of part of the body of cancer patients. For example, the treatment of malignant pleural mesothelioma could also include the abolition of the lungs caused by the execution of a lung resection.
• The radiation therapy - Bring the affected party of high-energy radiation to kill the malignant cells
• chemotherapy - using chemicals or drugs to destroy malignant cells, either by injection or by the patient intravenously or through direct placement in the chest or the abdomen (intracavitaire chemotherapy).

In addition to these three options, the investigations are still under way for the latest and most effective treatment options. Clinical studies have an important role in the development of new choice of treatment.

Mésothéliome forecast

In the case of mesothelioma, the prognosis is not as precise as with other diseases, less serious. This is because normally the prognosis depends on the phase in which a disease is detected. The mesothelioma is usually very late detected, the patient, so that it becomes difficult to maintain the healing or for the life of a patient after treatment. Regardless of the available statistics are not as reliable as we would like. Although it was not easy to determine which of the two - or pleural effusion peritonealer - Mesothelioma is difficult to stage, the experts agree that in general, the prognosis is very difficult for the two.

But recent studies and researches have shown that patients with mesothelioma is perhaps not as bad as it was originally believed start. These data are included in the following tables.

Stage discovered Mesothelioma chances of survival (No. years) Percentage of Patients

Mid at an advanced stage 3 years 10%

5 years 5%

First Steps 2 years 50%

5 years 20%

It is not that general information on the prognosis of Mesothelioms. There are certain data available to Internet-n-scenarios and situations.
