Mesothelioma Cancer

Clinical research to treat malignant mesothelioma is very active and although no treatment has yet proved entirely successful, there exist a range of treatments available to individuals diagnosed with the disease. There are three types of standard treatments used to treat malignant mesothelioma which include: surgery, radiation therapy, and chemotherapy.

Mesothelioma Cancer | Asbestos

Surgery

Surgery for malignant mesothelioma is divided into a number of sub-classes, which are specially designed to limit the disease for individuals with particular strains of the disease.

Extrapleural pneumonectomy is a severe form of surgery in which the entire lung and a portion of the lining of the chest, the diaphragm, and some or the entire sac which surrounds the heart is removed.

Wide local excision is a form of surgery which targets and removes the cancer and a limited amount of the healthy tissue surrounding the cancerous region.

Pleurectomy and decortication removes part of the covering of the lungs, as well as the lining of the chest and portions of the outside covering of the lungs.

The surgical procedure pleurodesis is a distinct technique insofar as it employs a blend of chemicals and/or drugs to create an intentional scar between the layers of the pleura. Post surgery, the space created by the scar must be drained, using either a catheter or chest tube, and is then filled with a chemical which inhibits the accumulation of fluid in the pleura cavity.

Radiation

The second primary medical technique used to fight the development of malignant mesothelioma is radiation. Radiation therapy, as applied to malignant mesothelioma uses the same basic technology as other forms of medical radiation insofar as the technique employs high energy x-rays to kill cancer cells. The process is divided into two broad categories:

External radiation therapy is a technique in which a machine sends radiation in a targeted stream at a certain portion of the body, and in so doing it kills the cancerous cells in its purview.

Internal radiation therapy, by contrast, uses not an external machine, but rather needles, seeds and catheters to place radioactive substance directly on or near the cancer. While the precise method of implementation will of course depend upon the type and stage of the illness, what is constant within this category is that the goal is to get the radiation placed directly onto the cancerous area and in so doing provide a more concentrated and directed dosage.

Chemotherapy

The third standard malignant mesothelioma treatment is Chemotherapy. Chemotherapy uses drugs which target cancer cells and stop them from dividing and thus prevent their growth.

In systemic chemotherapy, the drug can be taken by mouth or injected, but either way the goal is to have it reach cancer cells by means of the body’s own blood circulation system. In regional chemotherapy, the drug is placed directly onto the target area. And finally, combination chemotherapy involves the use of two or more anticancer drugs which can be administered either orally or through injection.

Malignant mesothelioma is a difficult disease for anyone to bear, however, educating oneself as to the options available is an important step for making the process more manageable.

Mesothelioma Treatment options depend on many factors such as time, place and the age of patients and wishes. Important external factors to take into account the much experience with the oncologists at mesothelioma, and if so, whether a city-rural area to be transferred to a big city or for the aggressive palliative care. Survival rate of patients is determined to up to one year, while some major centres were of a cancer of the life expectancy after diagnosis, so as to be that five years longer. Screening By imaging tests allow doctors to see a photo on the side of the cancer. These tests can also use the X-ray computed tomography (CT) or MRI (magnetic resonance imaging). New tool for early detection: The test Mesomark The Food and Drug Administration has just the (January 2007), the first test for the in-vitro mesothelioma. Mesomark The test, developed by Fujirebio Diagnostics is in the patients with epithelioid biphasic mesothelioma or by a simple blood test. The test measures proteins in the blood, changes in the volume of the patient’s tumor is an important factor for the monitoring of the patient and the response to therapy. Modern Art treatment Surgery, the removal of the entire lung and in a part of the edition of the chest, the diaphragm and the part of the bag, which surrounds the core. Thoracoscopie is the insertion of an endoscope, which is a small narrow tube with a small cameria pleural fibrosis in the cave, situated directly on the tumor. Pathologiste, a biopsy, a tissue. Often chemical pleurodesis (emptying the liquid in the space intrapleurale), during the same procedure. Médiastinoscopie, another type of surgery is sometimes used for the measure from the stage of the disease, when enlarged nodes are using imaging techniques. Laproscopy mesothelioma in the techniques of imaging in patients indicate that the tumor invaded by the diaphragm. This information is important in assessing a patient potential for pleurectomy or extrapleuralen lung resection. Radiation Therapy (with high doses of X-rays or other high-energy radiation for cancer cells. Irradiation - Although the mesothelioma tumours are very resistant to radiation therapy, sometimes, these treatments to alleviate the symptoms that arise from the growth of tumors, such as the blocking of a main blood vessel problem. Radiation therapy is generally at the opening of the chest drain sites to prevent the growth of tumors along the paths in the chest wall. Chemotherapy - is used to prevent the cancer cells to grow and divide. Immunotherapy: intraopérative Intrapéritonéale heated chemotherapy is necessary to deprive the tumor as much as possible, followed by the direct administration of a heated between (40 and 48 ° C), chemotherapy, in the abdomen, while 60 to 120 minutes, then Abgetropfte. Palliative care procedures Pleuropéritonéale shunt is a procedure in which a catheter under the skin of pleural mesothelioma in the abdominal cavity. This procedure raises concern that the catheter may cause damage by anchoring himself in the abdomen. Pleurectomy a palliative procedure, if further surgery is not an option. The procedure can not effectively remove tumors. It is regarded as the most effective means to control the pleural effusion (water storage), in cases where the expansion of the lungs is by mesothelioma. Potentially curative These procedures are “intent” healing. Pleurectomy / Peel, usually in patients with early stage disease pleural mesothelioma (stage I and stage II select), and tried all gross tumor. Extrapleural Pneumonectomy for surgery is the removal of a diseased lung, a portion of the Pericardium a part of the membrane and a part of the parietal pleura. This type of surgery is often used to a clever and traditional mesothelioma in combination with chemotherapy and / or radiation therapy, gene therapy, immunotherapy, or photodynamic therapy. Cytoreductive Surgery removed tumors visible in the abdominal cavity. The rest of the cancer cells by intra-peritoneal hypertermiques (heated) chemotherapy (IPHC), then delivered the abdominal cavity. New treatments or experimental Gene Therapy: The best-known gene, called the p53 tumor. When this gene is damaged or missing, or genes, oncogenes cancer proliferate in a normal pace. The main axis of gene therapy for mesothelioma is a virus injected, has been changed, in the laboratory. The virus is in the room pleural mesothelioma in the chest, where the mesothelioma developed to be an attempt to kill cancer cells. Vaccine or drug therapy The mesothelioma patients have a high vascular endothelial growth factor (VEGF), a chemical in the blood vessels, that the people of other types of cancer. The experiments are currently under way to check whether the VEGF can be blocked, making the vehicles of growth of blood vessels pull mesothelioma tumors. Bevacizumab is a vaccine against the drug currently in use. A process has recently declared that the drug increases the chances of survival for patients with lung cancer. An American Phase 2 bevacizumab procedures tested to mesothelioma, in combination with chemotherapy drugs. Bevacizumab is still in the testing phase, and much more important process are necessary before we know it in the treatment of mesothelioma and other types of cancer. The photodynamic therapy (PDT) In photodynamic therapy drug called a photosensitising injection into the bloodstream and into the cells of the body through which the light-sensitive cells. If the patient is in the laser light, the cells. PDT is used in combination with surgery for the treatment of patients in the early stages of mesothelioma. PDT is in the stages of the proceedings and very experimental. The clinical trials and election law The clinical studies of the research with the help of an investigation of individuals affected by cancer. The National Cancer Institute says that the purpose of most clinical trials are designed to test new drugs against cancer or new methods for diagnosis, prevention or early detection of cancer. The conditions for the approval for clinical trials is not the same, each study contains specific guidelines for participation. Some procedures allow for the participation of other treatments have failed, while others require that the patient is not treated. The choice of a clinical trial may only after a medical consultation. Examinations for the Prevention - ways to reduce the risk or the likelihood of cancer to develop. Most tests are conducted on the prevention, in which healthy people who had no cancer. These tests, drugs, vitamins or diet to reduce cancer risk. Some procedures are interviews with people who have cancer, and want to prevent the return of cancer (Relapse), or the risk of developing a new type of cancer. Screening Trial - ways to detect cancer. They are often carried out to determine whether the cancer before finding the causes of the symptoms reduces the chances of dying of the disease. These procedures are people who show no signs of cancer. Diagnosis Cancer Trials - develops new tests or scans The trials for the treatment - studies of new drugs or combinations of drugs, new treatment options, and new ways of processing Quality of life processes explore how the comfort and quality of life of patients with cancer and survivors of cancer. These tests can be opportunities for the people who are suffering from nausea, vomiting, sleep disturbances, depression, or adverse reactions, cancer or treatment. Trials Genetics Study - sometimes are part of another clinical trial of cancer. The genetic component of the negotiations may affect the way can influence the genetic detection, diagnosis, or a response to a therapy against cancer. The clinical studies are in 4 phases: The phase 1 of the examination, if the attempt to treat drug is safe or harmful, and the efforts to establish the correct dosage. Phase 2 trials check the effectiveness of the treatment. Phase 3 tests to examine a new treatment against the current standard therapy. If it leads to better results, it could be the new standard treatment. Phase 4 trials are after a drug was approved. They collect information on the side effects of the safety and the long-term risks and benefits of a drug. The research is underway, the possibilities for improving the treatment of Mesothelioma, but clinical trials are not all in new and better treatments. After the examination, he discovered that the treatment in the test does not work, or it is the worst side effect, the existing forms of treatment. But for the researchers and doctors, and at the end for the patients it is important that this research is in progress.

The surgery is a major step in the confirmation, and knowing the type of cancer. It can be used in patients with the combination of radiation and chemotherapy used before and after surgery.

Pleurectomy:
The most common surgery for the treatment of Mesothelioma pleurectomy, in which doctors open the chest of the patient and remove excess liquid or a tumor from the wall of the lung (pleura). Although this method to control the accumulation of fluid and reduces the pain, it’s not a cure. However, if the tumor is in its original form and does not have much further, pleurectomy can increase the survival rate of patients when used with chemotherapy and radiation therapy. Moreover, a pleurectomy can in patients less than the approval of the conditions for the health and the death rate is lower than the extrapleuralen lung resection.

Extrapleural Pneumonectomy (EPP):
Extrapleural lung resection (EPP) is a serious and invasive form of surgery, the patients on Mesothelioma. In this treatment is a part of the lung, pleura (the wall of the lung tissue), pericardium (lining of the heart) and the mid-aperture, so that the tumor cells are removed. He takes the progress of mesothelioma, which the patient to breathe without a problem. It is normally associated with patients who are in the early stages of the disease, and when the tumor in the chest cavity. EPP is recommended for patients with a good heart and lung conditions, so that the severity of post-operative term. Although the operation in combination with chemotherapy and radiotherapy promising results, there is no guaranteed cure. The studies have shown that patients with therapies extrapleuralen lung resection, and have an average life span of 35 months after surgery, compared to only 9 months pleurectomy. But some doctors question of surgery, to the high risks arising from the internal bleeding, blood clotting, inflammation of the lungs, the accumulation of pus, shortness of breath and even death. So many surgeons recommend that the idea pleurectomy place of the technical complexity of the EPP.

Thoracentèse:
A small surgery is often performed on patients who can not be expanded or EPP pleurectomy, thoracentèse. In thoracentèse, thoracic surgeon inserts a needle into the chest of the patient to remove the excess fluid accumulated in the wall of the lung (pleura). This method is still not the cancer cure, but the symptoms to alleviate painful mesothelioma. In some cases, talc or other officials with a patient in the vaults of the scar in the chest wall and to help them breathe properly, without the tumor to increase to a certain degree.

Paracentèse:
Paracentèse is a similar method, with a needle to the liquid, but the abdominal section of the body. It follows the same procedure for the recovery of the liquid mucosa of the stomach and other organs abdominal muscle training. Patients with peritoneal mesothelioma paracentesis are responsible for the surgery.

As with any cancer, the treatment of mesothelioma is dependent on the localization of cancer, the progression of the disease, age, so that the health condition of the patient.

It is the oncologists, focusing on the disease, which is to decide from the treatment. The disease is difficult to treat and, in most cases, the prognosis is bleak. The options for treatment include:

1st If the diagnosis is in the early stages of the operation can be recommended to all tissues of cancer patients. That means thoracoscopie, FCAV or video support-thoracic surgery, médiastinoscopie (for the production), or laproscopy. Often, the doctors recommend palliative procedures such as chest tube pleurodesis and drainage, thoracoscopie and pleurodesis, pleuroperitonial shunt or pleurectomy, that the symptoms of mesothelioma than the disease.

2nd Radiation aggressively is necessary for the patient and that mesothelioma is often used in combination with surgery or with the aim of curbing the symptoms, palliatively. Research on the use of radiation therapy use of implants or UV light is in therapy than conventional radiation therapy damage surrounding healthy tissue.

3rd The chemotherapy is an option, and in the vicinity of 12-20% of patients in the fight against drugs. Drugs to treat cancer, the cancer cells and destroy their propagation. In mesothelioma, the chemotherapy is not as a curative. The aim is to prevent the spread of the disease, reducing the tumor prior to surgery, known under the name of neoadjuvant therapy, the destruction of the entire rest of the tumor in the body after surgery, and to alleviate the pain and the discomfort of others, the palliative chemotherapy . The experts recommend that the limitation premetrexed with cisplastin. These drugs have shown positive results, and that is now the standard for the treatment of non companionable mesothelioma from the surgery.

4th Biological therapy, the interleukin-2.

5th The immunotherapy, in which the body’s immune system is stimulated to fight the disease. Modifiers of biological, BRMs, in the treatment. This improvement of the functions of the immune system, which regulate metabolic reactions, the growth of cancer, cancer to change the cell division; block or reverse the process, the training of cancer, and prevention of the spread of cancer.

6th The gene, where an attempt will be made to the sequence of the gene that causes the cancer. These are two types, and the replacement gene, gene knockout.

7th Administration of lovastatin, a cholesterol-lowering medicines.

8th Photodynamic therapy with a drug light is activated with a laser, this happens during the operation ablation of tissue cancer patients.

9th Drain the fluid in the chest or abdomen, followed by the introduction of drugs into the cave, in order to avoid the accumulation of fluid is for the patients, the uncontrolled accumulation of fluid and intense discomfort, the resulting.

10th Combination Therapy or therapy, which means Trimodal surgery with radiotherapy and chemotherapy.

Often, the drugs are also used. Proposals in this holistic type of treatment focused on a patient physical, mental, emotional and spiritual well-being.

In the case of mesothelioma, which is incurable, we can be for clinical trials of new therapies that are currently in several laboratories and research centres. The best advice, on the stands, it is recommended that the treatment by the doctor or oncologist.

The earlier the symptoms of malignant pleural mesothelioma are very similar to those with other lung diseases such as pneumonia or lung cancer. The symptoms tend, even on very gradually, and therefore can long remain undetected for some time. Shortness is one of the earliest and the typical symptoms of pleural mesothelioma. That can, as a recent onset of shortness of breath or an increased shortness of breath. Shortness can be an accumulation of fluids (pleural effusion), in the space around the lung. This accumulation of fluid at regular intervals can be removed to facilitate breathing. Some substances may also in the space between the membranes pleurales where fluid collects. These substances lead to an inflammatory response in the pleurales membranes, which are merging, thus preventing the training and the collection of more liquid.

The pleural thickening of the membranes by the growth of cancer cells are also the lung function and contributes to the shortness. Sometimes the thickening of the tissue can order the removal of the operation again some lung function. The process is known as referral décortication or pleurectomy.

Mésothéliome clever tend to be fairly quickly to other parts of the body, and this difference may be additional symptoms. If pleural mesothelioma on the chest wall and other tissues of the chest, it can cause severe pain. Even before the cancer, the pain in the chest, particularly in the lower part of the chest and on the side, can be experienced. Chest pain gradually growing bigger problem than the cancer grows. A pain can be processed, with a strong relief of pain with drugs and radiation therapy. If pleural mesothelioma on the lung, the symptoms that are usually having lung cancer, such as cough and hoarseness blood, can be present.

As with other types of cancer, the effect of pleural mesothelioma is very common. The increase in the metabolism of cancer cells, which by the results of fever, weight loss and fatigue.
