Mesothelioma Cancer Treatment - Clinical Trials

Mesothelioma is a rare and severe type of cancer. The treatments available are not effective in treating the disease. This also arises partly from the fact that the disease is not well known. New methods and procedures need to be developed in order to improve the effectiveness of the treatment. Clinical trials are studies directed for the purpose to develop new treatments and to evaluate the effectiveness and safety of these new treatments.

There are basically four phases in a clinical trial and each phase has its goals. The phases are as follows:

Phase 1: This phase studies the safety and side effects of a new drug. It tries to determine the best way that this new drug is administered and tries to determine the appropriate dosage. It is important to state that not only new drugs are studied in a clinical trial but treatments such as surgery, radiation therapy and other treatments may also be studied. Before any treatment is tested on humans it has been already tested in the laboratory, usually on animals, but its side effects on humans will not accurately be determined until it is actually tested on them.

Phase 2: In this phase the treatment's effectiveness to fight mesothelioma will be studied and the treatment's safety will further be evaluated.

Phase 3: the new treatment is compared to existing treatments in order to study side effects and confirm its effectiveness.

Phase 4: Information is gathered in order to determine how an already approved treatment can be used to treat other diseases.

To be eligible for a clinical trial the patient should have certain characteristics. Eligibility depends on the stage of the disease, the age of the individual and many other factors. There are different types of clinical trials and eligibility is not the same for all. There is no guarantee that a clinical trial will produce the desired results. Further more the patient is obviously exposed to certain risks. Therefore it is very important that the patient talks with his physician and is well informed about the advantages and risks involved and the adequacy of clinical trial in his or her particular situation.

Treatment Options for Pleural Mesothelioma

Mesothelioma is a deadly cancer that is directly attributed to asbestos exposure. There are three forms of mesothelioma. These forms are pleural mesothelioma, peritoneal mesothelioma and pericardial mesothelioma. This devastating cancer attacks the mesothelium, or the protective lining of the lungs, abdominal cavity, and heart respectively.

Of the three forms of mesothelioma, pleural mesothelioma is the most common. When asbestos is manufactured, mined or disturbed asbestos fibers are released into the air. Those working with or around asbestos inhale and ingest these fine particles. Over an extended period of time, mesothelioma can take 20 to 60 years to manifest, these asbestos particles can cause normal pleura in the lining of the chest to become abnormal, causing pleural mesothelioma.

Some of the most common symptoms of pleural mesothelioma are persistent cough, shortness of breath, bloody sputum, weight loss, fever, swelling of the face and neck, raspy voice and trouble swallowing. Due to the symptoms of pleural mesothelioma mimicking symptoms of other conditions it may go undiagnosed when the need to start mesothelioma treatment immediately is vital.

After a definitive diagnosis of pleural mesothelioma has been established there are several mesothelioma treatment options that can be undertaken. The type of mesothelioma treatment will depend on several key components. These factors are the extent of the disease, the patient’s history and age, and the location of the tumor.

The most common forms of mesothelioma treatment, for those with pleural mesothelioma, are a pneumonectomy, radiation, chemotherapy, and palliative therapies. One form of mesothelioma treatment is a pneumonectomy, or the removal of the cancerous lung. Depending on the spread of the disease, parts of diaphragm may be removed as well. A pleurectomy may also be used to treat pleural mesothelioma by removing parts of the chest and surrounding tissue. The ability for these procedures to be performed are dependent on the patient’s overall health, spread of the disease, and the amount of asbestos exposure.

Radiation treatment is another form of mesothelioma treatment for those suffering from pleural mesothelioma. Radiation therapy works by placing a radioactive source in the area of disease. The use of radiation has the benefit of destroying cancerous tissue while not exposing healthy cells. This form of mesothelioma treatment can be performed in conjunction with surgery or alone if the individual is to ill for surgery.

Chemotherapy is another common form of mesothelioma treatment for those with pleural mesothelioma. This high toxicity drug is usually administered by injection or in pill form. Some side affects from chemotherapy include nausea, vomiting, hair loss, fatigue and weight loss. This form of mesothelioma treatment is not targeted to a particular area like radiation therapy. Therefore, the drugs used have to make their way through the body to the cancerous area or areas. Unfortunately, this has the disadvantage of exposing healthy tissue to the toxicity of the chemotherapy drugs.

Palliative therapies are also used as a form of mesothelioma treatment for those with pleural mesothelioma. This involves removing excess fluid by needle and suction from the affected areas. Drugs are also used in order to keep fluid accumulation under control.

As additional research is performed on pleural mesothelioma more treatment options may become available. Keeping informed of new mesothelioma treatments is paramount if diagnosed with this devastating disease.
