An Overview of Mesothelioma Treatment Options

Mesothelioma treatment options depend on many internal factors such as: stage, location, and the patient's age and desires. Important external factors to consider include the experience level of the oncologist with mesothelioma cases and whether or not a rural dweller would have to be transferred to a larger city for aggressive treatment or palliative care.

Patient survival rate is determined to be up to a year; while some leading cancer centers have reported life expectancy after diagnosis to be as much as five more years.

Mesothelioma Treatment Options

Screening

An Overview of Mesothelioma Treatment Options

Imaging tests allow doctors to see a picture of the cancer site. These tests could include x-rays, CT scans (computed tomography), or MRI (magnetic resonance imaging).

New Screening Instrument: The Mesomark Test

The Food and Drug administration has just approved (January 2007) the world's first in-vitro test for mesothelioma. The Mesomark assay test, developed by Fujirebio Diagnostics is administered to patients diagnosed with biphasic or epithelioid mesothelioma by a simple blood test. The test measures proteins within the blood that reflect changes in the patient's tumor volume, a key factor for monitoring patient status and response to therapies.

Traditional Treatment Types

Surgery, removal of the entire lung and a part of the chest lining, the diaphragm and part of the sac surrounding the heart.

Thoracoscopy is the insertion of an endoscope which is a small narrow tube, containing a tiny cameria into the pleural cavity to look directly at the tumor. Pathologist's perform a biopsy to collect a tissue. Often, chemical pleurodesis (draining fluid in the intrapleural space), can be accomplished during the same procedure.

Mediastinoscopy, another type of surgical incision is sometimes used to stage the extent of disease when enlarged nodes are seen using imaging techniques.

Laproscopy is used in mesothelioma patients when imaging techniques suggest that the tumor has penetrated through the diaphragm. This information is important in evaluating a patient for potential pleurectomy or extrapleural pneumonectomy.

Radiation Therapy (using high-dose x-rays or other high-energy rays to kill cancer cells.

Radiation - Although mesothelioma tumors are highly resistant to radiotherapy, these treatments are sometimes used to relieve symptoms arising from tumor growth, such as obstruction of a major blood vessel.

Radiotherapy is commonly applied to the sites of chest drain insertion, in order to prevent the growth of the tumor along the track in the chest wall.

Chemotherapy - is used to stop the cancer cells from growing and dividing.

Immunotherapy: Heated Intraoperative Intraperitoneal Chemotherapy requires the removal as much of the tumor as possible followed by the direct administration of a heated between (40 and 48°C) chemotherapy agent, into the abdomen for 60 to 120 minutes and then drained.

Palliative Procedures

Pleuroperitoneal Shunt is a procedure where a catheter is placed under the skin from the pleural to the peritoneal cavity. This procedure raising concerns as the catheter can cause damage by embedding itself into the abdomen.

Pleurectomy, a palliative procedure, may be performed when more extensive surgery is not an option. The procedure does not effectively remove all tumors. It is considered the most effective means of controlling pleural effusion (fluid buildup) in cases where the lung's expansion is restricted by the mesothelioma.

Potentially Curative Procedures

These procedures are performed with "curative intent".

Pleurectomy/Decortication is usually performed on patients with early stage pleural mesothelioma disease (Stage I and selected Stage II), and attempts to remove all gross tumor.

Extrapleural Pneumonectomy is surgery to remove a diseased lung, part of the pericardium, part of the diaphragm and part of the parietal pleura. This type of surgery is used most often to treat malignant mesothelioma and is combined with traditional chemotherapy and/or radiation, gene therapy, immunotherapy or photodynamic therapy.

Cytoreductive Surgery removes visible tumors in the peritoneal cavity. The remaining cancer cells are treated by Intra-Peritoneal Hyperthermic (heated) Chemotherapy (IPHC) and then delivered to the abdominal cavity.

New or Experimental Therapies

Gene Therapy: The best known tumor suppressor gene is called p53. If this gene is damaged or non existent oncogenes or cancer genes multiply at an abnormal rate. The main focus of gene therapy for mesothelioma involves injecting a virus that has been modified in the laboratory. The virus is injected into the pleural space in the chest, where mesothelioma develops as an attempt to kill the cancer cells.

Drug or Vaccine Therapy

Patients with mesothelioma have much higher levels of vascular endothelial growth factor (VEGF) a chemical controlling blood vessel than people with any other type of cancer. Trials are being conducted to see if VEGF can be blocked, thus stopping the growth of blood vessels feeding the mesothelioma tumors.

Bevacizumab is a drug vaccine currently in use. One trial recently reported that this drug may increase survival for patients with lung cancer. An American phase 2 trial tested bevacizumab for mesothelioma, in combination with chemotherapy drugs. Bevacizumab is still in the experimental phase and much larger trials are needed before we will know how effective it will be in treating mesothelioma and other types of cancers.

Photodynamic Therapy (PDT)

In Photodynamic therapy a drug called a photosensitizing agent is injected into the bloodstream and absorbed by the body's cells rendering the cells sensitive to light. When the area to be treated is exposed to laser light, the cells are killed. PDT has to be combined with surgery to treat patients in the early stages of mesothelioma. PDT is still in the trial stages and very experimental.

Clinical Trials and Eligibility

Clinical Trials provide research by using a sampling of people affected by the cancer. The National Cancer Institute states that the purpose of most listed clinical trials is to test new cancer treatments or new methods of diagnosing, screening for or preventing cancer.

Eligibility requirements for clinical trials are not the same; each study has specific guidelines for participation. Some trials allow participation after other treatments have failed, while others require that the patient did not have prior treatment. Choosing a clinical test should only be done after a medical consultation.

Prevention trials - study ways to reduce the risk, or chance, of developing cancer. Most prevention trials are conducted with healthy people who have not had cancer. These trials use drugs, vitamins or diet to reduce risk of cancer. Some trials are conducted with people who have had cancer and want to prevent the return of cancer (recurrence), or reduce the chance of developing a new type of cancer.

Screening Trials - study ways to detect cancer. They are often conducted to determine whether finding cancer before it causes symptoms decreases the chance of dying from the disease. These trials involve people who do not have any symptoms of cancer.

Diagnostic Cancer Trials - develops new tests or scans

ng>Treatment Trials - studies new drugs or combinations of drugs; new ways of giving treatment, and new types of treatment

Quality of life trials explore ways to improve the comfort and quality of life of cancer patients and cancer survivors. These trials may study ways to help people who are experiencing nausea, vomiting, sleep disorders, depression, or other effects from cancer or its treatment.

Genetics Study Trials - are sometimes part of another cancer clinical trial. The genetics component of the trial may focus on how genetic makeup can affect detection, diagnosis, or response to cancer treatment.

Clinical trials are conducted in 4 phases:

Phase 1 trials look at whether a trial treatment drug is safe or has any harmful effects and attempts to establish the right dosage required.

Phase 2 trials look at the effectiveness of the treatment.

Phase 3 trials test a new treatment against the existing standard treatment. If it yields better results, it may become the new standard treatment.

Phase 4 trials are carried out after a drug has been licensed. They collect information about side effects, safety and the long term risks and benefits of a drug.

Ongoing research attempts to improve mesothelioma treatment options but clinical trials will not all result in new and better treatment. After testing, it may be discovered that the treatment being tested does not work, or that it has worse side affects than existing treatments. But, to researchers and doctors, and in the end for patients, it is crucial to keep this research going.

Asbestos, asbestos exposure and mesothelioma - an overview

Asbestos
The literal meaning of the word "asbestos" comes from Greek and means "indelible." Rightly named, this long fibrous mineral was widely used for thousands of years because of its refractory properties. In fact, the ancient Greeks used asbestos for burial dress of kings, which should be burned. Both the Greeks and Romans used asbestos fiber napkins to clean it by throwing into the fire.

In modern times, has asbestosused since the same reason. In addition, the mineral is very resistant to heat, salt water, corrosion and other biological processes. It is lightweight, extremely strong and can be woven cloth or mixed with building materials like concrete. Asbestos has been used for insulation in a variety of products and structures, including the ceilings, walls, toaster and hairdryer. It was generally used on ships and in military applications, and was at one point its use evenOn behalf of the U.S. military.

Unfortunately, it is now known that asbestos that poses huge health risks. Pleural plaques, asbestosis and mesothelioma cancer are just some of the diseases that can be caused by asbestos, especially if the exposure is extended and / or repeated. Although the Roman naturalist Pliny the Elder observed a "disease of the lungs" in slaves, who worked with the fiber, and the first case of asbestosis has been established already in the 1920s,in England, the material was used in industrial applications, and its adverse effects have been ignored or even covered up on purpose, for decades.

Asbestos exposure
Asbestos, once disturbed there, tiny particles that are typically unseen by human eyes in the air. once inhaled, these particles are released into the mesothelium that protects the outside covering the heart, lungs and stomach. The fibers can not be exhaled or otherwise removed from theBody as soon as they filed into the body soft tissues.

Exposure to dangerous asbestos fibers that caused the development of asbestos cancer in a variety of different people and professions over the years. The exposure was through the production of asbestos from the earth, construction or demolition occurred asbestos-containing construction materials and even through clothing, laundry, contaminated by asbestos. Various asbestos-related diseases, including mesothelioma, werediagnosed people from all walks of life.

Mesothelioma
Mesothelioma is an aggressive cancer whose only known cause is asbestos exposure. Mesothelioma often has a long latency period, and even decades can go undetected for years or. Over time it is diagnosed cancer in advanced stage of a difficult rule reaches to determine what very undergo how to treat mesothelioma. This means that we do not yetunderstand the full impact of widespread use of asbestos in the first decades of the 20th Century, since so many people and especially diagnosed.

Mesothelioma symptoms are usually unspecific and resemble those of common diseases, such as viral pneumonia, heart disease, flu and bronchitis. These symptoms include dyspnea (shortness of breath) or causing difficulty breathing, coughing and / or coughing up blood, chest or abdominal pain of too much fluid weightLoss, hoarse voice, difficulty swallowing, fever, anemia, intestinal obstruction, inability to sleep, and loss of appetite. Because of the similarity to many other diseases, mesothelioma is often misdiagnosed or not diagnosed accurately, until it has reached an advanced stage. As with all cancers, mesothelioma can be better treated if diagnosed early, but given the long latency period and its symptoms' similarities to other health issues, it rarelyis.

Mesothelioma is currently incurable. There is, treatments that are used to slow the disease progress or provide palliative care. Established therapies such as chemotherapy and radiation, experimental treatments and holistic therapies can all be used individually or in combination.

Asbestos, Asbestos Exposure, and Mesothelioma - An Overview

Asbestos
The literal meaning of the word "asbestos" comes from the Greek word meaning "inextinguishable."

Mesothelioma
Mesothelioma is an aggressive cancer whose only known cause is asbestos exposure. Mesothelioma often has a long latency period, and can remain for years or even decades undetected. By the time of diagnosis the cancer has usually reached an advanced stage, decide on how to undergo mesothelioma treatment very difficult.
