Mesothelioma Treatment

Posts Tagged ‘Pleural Mesothelioma’

Pleural mesothelioma, also known as mesothelioma of the pleura, is a tumor in the tissues surrounding the lungs. The pleura is a thin layer of tissue that surrounds the lungs and lines the inside of the chest. In order to protect the lungs, the pleura produces a small amount of a coating fluid which helps the lungs causing more uniform movements during breathing.

Symptoms of pleural mesothelioma may include breathing problems, chest pains, back pains, pains in the ribs, fluid accumulation in the tissue lining the lungs, hoarseness, coughing up blood, swelling of the face and arms, muscle weakness, paralysis and sensory loss.

Pleural mesothelioma benign (not cancerous)
benign pleural mesothelioma is a noncancerous tumor that has spread to other body organs. If the tumor is large, could put pressure on the lungs and cause breathing problems and pain.

Malignant Pleural Mesothelioma
Malignant pleural mesothelioma is cancerous and can spread to other parts of the body. This rare form of cancer found in the pleural tissue of the lung. Exposure to asbestos is considered the primary cause of malignant pleural mesothelioma.

The three types of mesothelioma
Mesothelioma is a rare type of cancer. It affects different parts of the mesothelium, the membrane that covers and protects most internal organs. Depending on the bodies that covers and protects the mesothelium has different names and forms of mesothelioma are named in relation to these different membranes.

For example, the mesothelial tissue, or membrane that surrounds the lungs and lines the wall of the chest cavity called pleura. Cancer of this membrane is called pleural mesothelioma.

The heart is covered by the pericardium. Cancer of the membrane is
called pericardial mesothelioma.

The membrane that surrounds most organs of the abdominal cavity is known as the peritoneum, therefore, cancer of the membrane is called peritoneal mesothelioma.

Regardless of which bodies are covered by the mesothelium, is composed of two layers of cells. The first layer surrounds each organ closely. The second layer forms a sac around it. Between these two layers, the mesothelium produces a lubricating fluid that allows organs to move easily. This lubrication allows the lungs to expand and contract effortlessly, while breathing. It also allows our heart to beat smoothly.

Pleural mesothelioma
Pleural mesothelioma is caused by tumors, malignant (cancerous) tumors that form in the tissue lining the lungs and chest cavity. The fluid usually collects between the lung lining and chest cavity. This is called pleural effusion , which usually causes shortness of breath and pain.

Pleural mesothelioma is, without doubt, the most common expression of malignant mesothelioma. Like all forms of mesothelioma, the people who have been exposed to asbestos for long periods (usually for working with asbestos or near it, or have lived near mines or factories where the ore was processed) are who are more likely to develop this type of mesothelioma caused by asbestos. However, relatives who inhaled the dust on clothing brought the workers and the people who were exposed for periods of not so long can also get this and other forms of malignant mesothelioma. In all types of this disease, the symptoms take from 10 to over 50 years to manifest.

The symptoms of pleural mesothelioma can resemble pneumonia and other diseases not so serious, so it is important to tell your doctor if you have been exposed to asbestos. Symptoms can be found shortness of breath, persistent cough or chest pain.

Although there is a type of mesothelioma in which tumors are benign
(noncancerous) in the pleura, most cases of pleural mesothelioma are malignant (cancerous).

Peritoneal mesothelioma
Peritoneal mesothelioma, which attacks the tissue surrounding the abdominal area, is much less common than pleural mesothelioma, but is also caused by the inhalation of fibers and asbestos dust.

Symptoms of peritoneal mesothelioma may be weight loss, abdominal pain and swelling, bowel obstruction, blood clotting abnormalities, anemia, and fever. In the same way as pleural mesothelioma, the symptoms of peritoneal mesothelioma are similar to those of other diseases less severe or different, which may hinder detection of the same, especially if your doctor does not know that you were exposed to asbestos.

Pericardial mesothelioma
Pericardial mesothelioma is an extremely unusual for mesothelioma caused by asbestos. Many of the symptoms are similar to those of pleural mesothelioma: constant cough, shortness of breath or chest pain. Another symptom is palpitations. As in other types of mesothelioma, the symptoms are similar to those of other diseases, therefore, tell your doctor if you have been exposed to asbestos.

In all types of mesothelioma, like other forms of cancer, cancer cells can metastasize (branches) from the original site to other parts of the body, generating other types of cancer.

Even with treatment, the prognosis for most people with mesothelioma is about 18 months after diagnosis, although some patients experienced four or more years after diagnosis and treatment. Without treatment, the prognosis is usually not more than four months.

Until recently, treatment options were limited, however, knowledge of the disease and progress in research, including clinical trials of new treatments, mean that the outlook for survival is becoming more encouraging.

Malignant mesothelioma is a cancer that occurs in the thin layer of tissue that covers most internal organs (mesothelium). The mesothelium has two layers of specialized cells called mesothelial cells.

Doctors divide mesothelioma into different types depending on the part of the mesothelium is affected. Mesothelioma occurs more frequently in the tissue surrounding the lungs (pleura). Other common sites include the lining of the abdomen (peritoneum) and the lining of the heart (pericardium).

Treatment for mesothelioma depends on the patient’s health and some aspects of cancer, including stage and location. Unfortunately, mesothelioma is usually an aggressive disease and most patients there is no cure. Mesothelioma is usually diagnosed at an advanced stage when it is not possible to remove the cancer through surgery. Your doctor can work to control cancer and the patient more comfortable.

Discuss treatment goals with your doctor. Some people want to do everything possible to treat cancer, even if it means enduring the side effects of a small room for improvement. Others prefer treatments that make them feel comfortable so they can have the best quality of life without symptoms time of life left in them.

- Surgery
Surgeons try to remove the mesothelioma cases are diagnosed in time. Sometimes it is not possible to remove all the cancer. In such cases, surgery may help reduce the signs and symptoms caused by the spread of mesothelioma in the body. Surgical options may include:

Surgery to decrease the fluid: pleural mesothelioma can cause a buildup of fluid in the chest, causing difficulty breathing. The surgeons inserted a tube or catheter into the chest to drain fluid. Doctors can also inject drugs in the chest to prevent fluid from coming back (pleurodesis).

Surgery to remove the tissue surrounding the lungs or abdomen: Surgeons can remove the tissue covering the ribs and lungs (pleurectomy) or the lining of the abdominal cavity (peritonectomy) to relieve the signs and symptoms of Mesothelioma.

Surgery to remove as much cancer as possible (debulking): If you can not remove all the cancer, surgeons try to remove as much.

Surgery to remove a lung and surrounding tissue: The removal of the affected lung and surrounding tissue can relieve the signs and symptoms of pleural mesothelioma. If you receive radiation therapy to the chest after surgery, this procedure also allows physicians to use higher doses because they do not have to worry about protecting the lungs from the harmful radiation.

- Chemotherapy
Chemotherapy uses chemicals to kill cancer cells. Systemic chemotherapy travels throughout the body and can reduce or slow the growth of pleural mesothelioma that can not be removed through surgery. Chemotherapy can also be used before surgery (neoadjuvant chemotherapy) to facilitate operation or after surgery (adjuvant chemotherapy) to reduce the possibility of cancer returning.

The compounds of chemotherapy also can be heated and administered directly into the abdominal cavity (intraperitoneal chemotherapy) in case of mesothelioma peritoneal or chest cavity (intrapleural chemotherapy) in case of pleural mesothelioma. With this strategy, mesothelioma chemotherapy can reach directly without harming healthy cells elsewhere in the body. This allows doctors to administer higher doses of chemotherapy drugs.

- Radiotherapy
Radiation therapy given high energy beams such as X-rays to a specific spot or spots on the body. Radiation can reduce the signs and symptoms in patients with pleural mesothelioma. Radiation therapy is sometimes used after a biopsy or surgery to prevent mesothelioma to spread to the surgical incision.

- Combination therapy
Surgery, chemotherapy and radiotherapy can be used in various combinations to treat both pleural mesothelioma and peritoneal mesothelioma.

- Clinical Trials
Clinical trials are studies of new methods of treatment of mesothelioma. People with mesothelioma may opt for the opportunity to try new types of treatment. However, the cure is not guaranteed. Carefully consider treatment options and see what clinical trials may be options for you. Participation in a clinical trial may help doctors better understand how to treat mesothelioma in the future.

- Treatment for other types of mesothelioma
Pericardial mesothelioma and mesothelioma of the tunica vaginalis are rare. Early-stage cancer can be surgically removed, however, doctors have yet to determine how best to treat cancers later in life. Your doctor may recommend other treatments to improve quality of life.

Any form of mesothelioma is very aggressive and often resistant to treatment. In addition, early diagnosis is so rare that the treatment of mesothelioma is usually not able to provide a complete cure.

However, with the development of new drugs and early detection techniques, the outlook is improving for patients with pleural mesothelioma, particularly because this is the most common form of mesothelioma is a much larger body of knowledge and research for the treatment patients. According to some ongoing studies, approximately 10 percent of all patients with pleural mesothelioma will survive three to five years after diagnosis, and about 5 percent will survive five years or more.

In general, patients with pleural mesothelioma has three options: surgery, chemotherapy and radiation therapy. Typically, patients receive a combination of two or more of these types of treatment.

Early detection of pleural mesothelioma patient’s prognosis improves considerably, and these patients have more extensive treatment options. If the disease is diagnosed with ample time, surgery to remove tumors located, followed by chemotherapy or radiation therapy to kill any remaining cancer cells may be a successful treatment. Curative surgery candidates must be in good health and that his cancer has not spread to other sections of the lungs.

Pleural mesothelioma patients who are not diagnosed early enough for curative treatment have fewer treatment options, and these are mostly limited to palliative care. These types of treatments are designed to relieve pain and discomfort and improve quality of life of the patient, instead of improving their prognosis. Palliative treatments include removal of the nuclei of pleural fluid spaces, and surgical removal of tumors to relieve pressure in the lungs.

As Asbestos Causes Cancer

The exact method by which asbestos causes cancer in mesothelial cells is currently unknown. However, there are four different theories:

1. Asbestos causes irritation of mesothelial cells, causing cell damage and eventually causing cancer
2. Asbestos fibers enter the mesothelial cells and damage molecules that are crucial for normal cell division
3. Asbestos fibers promote the formation of free radicals, which damage DNA and cause mesothelial cells turn into cancer cells
4. Asbestos fibers cause mesothelial cells produce molecules called oncoproteins that make cancer cells become

As with other malignant cancers, the key element is that the cells begin to divide continuously. Eventually these cells form tumors that inhibit the normal functioning of other cells and organs.

Symptoms

The first symptoms of malignant mesothelioma are not specific and can often resemble viral infections – this means that early diagnosis of this type of cancer is difficult. Symptoms such as shortness of breath, chest pain or a persistent cough are common. Night sweating, fever and weight loss are less common symptoms in people with pleural mesothelioma. Symptoms of peritoneal mesothelioma include pain or swelling in the abdominal area, nausea, weight loss, bowel obstructions, and anemia.

Diagnosis

Malignant mesothelioma diagnosis quickly and accurately is very important for two reasons. First, the correct diagnosis is essential to treat patients as soon as possible. The second reason is that some patients might want to try and obtain financial compensation from the company that was responsible for his exposure to asbestos.

The diagnosis is based on the patient’s symptoms, along with a physical examination. This I can include chest x-rays and other procedures designed to discover what kind of cancer is and what stage you are. The diagnosis is confirmed by biopsy or blood tests that determine whether cancer cells are present or not in the body.

Forecast

In general, the prognosis (life expectancy) for people with malignant mesothelioma is very poor. The first symptoms of the disease are so general that this type of cancer is very difficult to diagnose in the early stages, and when confirming an accurate diagnosis, about 50% of patients will die within a year.

Treatment

The most common treatments for malignant mesothelioma are surgery and chemotherapy, usually used in conjunction with each other. Surgical procedures typically involve the extraction of malignant cells to improve the quality of life for patients and continuing with chemotherapy to remove residual cancer cells.

Other forms of treatment are largely experimental. These types of treatment include immunotherapy and gene therapy. Immunotherapy involves manipulating the body’s own immune system in an effort to induce it to kill cancer cells. Gene therapy involves using a virus that has been genetically modified to infect cancer cells and make them produce molecules that are only capable of killing malignant mesothelioma cells.

What is mesothelioma?

Malignant Mesothelioma is a rare form of cancer that originates in the mesothelium, the membrane that covers and protects most internal organs of the body. The mesothelium has two layers, one surrounding the organ itself, and the other forming a lining bag inside it. Between these two layers are usually produces a small amount of liquid to lubricate the movement of organs protected. When the normal cells of the mesothelium out of control and multiply rapidly, it is called mesothelioma. The most common form of mesothelioma is mesothelioma pleural, which is generated in the lining of the lungs. Other forms are mesothelioma peritoneal, affecting the lining of the abdominal cavity, and mesothelioma pericardial, affecting the lining of the heart.

What causes mesothelioma?

Mesothelioma is almost always prevent exposure to asbestos fiber. Many people have been exposed in the military, others because of their work, others, secondarily, through contact with workers exposed. Because of its latency, the cancer may not occur for 20-50 years and higher after exposure.

What types of products generally contain asbestos?

These products generally contain asbestos in varying concentrations. This list is not exhaustive and is intended only as a general reference.

* Coatings shaped or molded, used for thermal insulation of pipes and boilers

* Asbestos spray used as fire protection in ducts, in firebreaks, panels, partitions in, in the floor boards, ceiling panels and around structural steel
* Insulating boards used for fire protection, thermal insulation, the partitions and pipes
* Coatings used asbestos in firebreaks and ceiling cavities
* Double-pressed cardboard, paper and paper products used for the insulation of electrical equipment, asbestos paper may also be used as a flame retardant coating on the panels of wood fiber
* All asbestos cement products, both flat corrugated sheets used for roofing or wall covering, cement products were also used in the gutters in the rain and water tanks
* Textured finish (such as Artex)
* Roofing material made of bitumen
* Tile Vinyl or thermoplastic

The pleura in a double layer covering the lung
The pleura is a membrane consisting of two thin sheets (visceral and parietal). They are the lungs and the inside of the chest cavity. In case of illness the space between the two pleural (pleural cavity) may fill with fluid, which causes breathing difficulties.

Asbestos case
It is assumed that about half of all malignant mesothelioma is caused by asbestos dust. Mesothelioma can develop decades after exposure to asbestos. If the asbestos dust may cause cancer should notify the appropriate accident insurance of the employer with whom the patient was exposed to dust, even if the patient is retired.

The lungs ‘walled’
The pleural mesothelioma is spread across the pleura and may invade nearby organs like the lungs or diaphragm. Arise breathing problems, coughing and chest pain. For the diagnosis is used in radiography, computed tomography or other methods of examination of the chest. It also collects fluid from the pleural cavity.

Surgery, radio and chemotherapy
The type of treatment depends on the spread of cancer. Typically, therapy is a combination of surgery, radio and chemotherapy. If pleural mesothelioma is diagnosed in a very advanced stage of recovery is not possible.

Pleural metastases
Much more frequent pleural mesothelioma are pleural metastasis, ie secondary tumors. Pleural metastases arise mostly from malignant tumors of lung, breast, stomach and esophagus.

Mesothelioma?

Abdominal mesothelioma is an intensely singular form of mesothelioma cancer. Usually described as peritoneal mesothelioma, a cancer affecting an intestinal lining, it is also well well well known as a peritoneum. In a bowel, is a serious membrane, which is also well well well known as a parietal peritoneum, and this surface continues until an intestinal peritoneum which lines an organ. With intestinal mesothelioma, an intestinal and parietal peritoneum lining has been influenced by an increase of carcenogenic cells.

Most often, cancer occurs when an intestinal specific initial developer pleural mesothelioma is that when a backing of a lung develops carcenogenic cells after transformation of asbestos. Pleural mesothelioma can then spread to the peritoneal form as well as funds peritoneal mesothelioma, which accounts for reduction than a third of all mesothelioma diagnoses.

How is peritoneal mesothelioma Contracted?

Abdominal or peritoneal, mesothelioma is caused by a transformation of asbestos fibers or asbestos dust. Asbestos is an element that is trailing from vermiculite, a vegetable that was heavily mined in the United States as well as about a universe in a 20 century. Asbestos was most commonly used as an insulation on the inside of a building a lot of attention since it was fire resistant, as well as were grown in cheap prices.
