Mesothelioma Prognosis

Mesothelioma prognosis and mesothelioma treatment options depend on the size of the tumor, the stage of cancer, potential surgical removal of any tumor, amount of fluid in the chest or abdomen, overall health and age of patient, specific type of mesothelioma cancer cell and whether cancerous cells are found anywhere else in the body.

The mesothelioma prognosis is determined through physical examination and the results of a number of medical tests designed to evaluate the rare asbestos cancer. Once a mesothelioma prognosis is finally determined, then treating this aggressive and rare cancer can begin. Early diagnosis and treatment are most important in looking for a favorable mesothelioma prognosis.

Since mesothelioma is usually diagnosed at an advanced stage, the statistics for one to five year survival are usually unreliable.

The two most common types of mesothelioma are peritoneal (abdominal) mesothelioma and pleural (lung) mesothelioma, with pleural mesothelioma being the most common. Peritoneal mesothelioma can be difficult to stage because of its rarity. The initial symptoms of pleural mesothelioma are subtle and often ignored resulting in the cancer being more advanced when it is finally diagnosed causing it to be difficult to stage. However, because it is the most common of the mesothelioma cancers, pleural mesothelioma has multiple staging systems.

Unfortunately, patients who have been diagnosed with peritoneal or pleural mesothelioma are often advised of a grim mesothelioma prognosis, one which can often be less than one year survival expectancy from the time of diagnosis. Of course every patient is so different requires a different mesothelioma treatment plan and as a result of the individuality of each patient, an accurate mesothelioma prognosis must be individualized by your physician.

The mesothelioma prognosis has several important factors such as the patient’s overall health at the time of diagnosis, exact type of mesothelioma tumor, size of the mesothelioma tumor and precise location of the mesothelioma tumor. Normally mesothelioma is located near the vital organs such as the heart and lungs which can cause severe consequences if the cancerous tumors begin to press on these vital organs. It is important to remember that the healthier a patient is going in to treatment for malignant mesothelioma then the patient generally responds better to treatment and has a greater chance of a prolonged survival.

After properly being diagnosed with mesothelioma and a mesothelioma prognosis is made, the doctor and patient will discuss treatment options. Because there is currently no known cure for mesothelioma, treatment options are designed to relieve symptoms, try to prevent metastasis and to prolong life while maintaining an acceptable quality of life.

Mesothelioma Diagnosis

The diagnosis for Peritoneal Mesothelioma begins with the thorough review of the patient’s medical history to determine symptoms and any past asbestos exposure, as well as a complete physical. In addition, sometimes physicians might request an MRI (magnetic resonance imaging) scan or an X-ray of the abdomen or chest region to help determine the location and size of the tumor. 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, clearly depicting the areas affected with the tumor.

In cases of pleural and peritoneal mesothelioma, fluid (effusion) may collect in the chest or abdominal region. In such cases, physicians may use a procedure known as fine needle aspiration to obtain a sample of this fluid for further testing. In addition, this procedure can be used to drain the effusion to temporarily relieve chest pain or other painful symptoms.

Usually, a biopsy of the tumor is required to confirm a diagnosis of mesothelioma, however, sometimes only an effusion sample is needed. Some of the procedures commonly used for the diagnosis of the peritoneal mesothelioma include peritoneoscopy, thoracoscopy, and biopsy. With peritoneoscopy, the doctor will use a tool called a peritoneoscope, which is placed inside an opening made in the patient's abdomen. Fluid, if found, is then drained; the process of draining the fluid is called paracentesis, and it requires a needle to be placed inside the abdomen in order to extract the fluid.

In thoracoscopy a doctor uses a special instrument called a thoracoscope in order to examine the patient's chest cavity. An incision is made in the chest wall, and the thoracoscope is placed between the patient's ribs. If the fluid is found in the chest, the doctor drains it from the chest cavity through a needle. A thoracoscopy commonly requires an anesthetic or some other form of pain suppression.

In a biopsy, if cancerous tissue is found in the patient's lungs or abdomen it will be extracted and examined by the doctor. This process helps the doctor determine potential ways of treatment and is usually done during one of the other two processes or may require additional surgery.

Pleural Mesothelioma

Malignant Pleural Mesothelioma is a lethal cancer that starts in the lining of the lungs. The main cause is believed to be unprotected contact with asbestos. Every year about 3000 new cases of this disease are reported in the United States. It is estimated that over the past fifty years nearly eight million people have been exposed to asbestos and that 300,000 new cases would be reported by the year 2030. The peak may be around 2020 and thereafter the incidence is likely to taper down because of the preventive measures that are being taken.

Like in all cases of cancer, early detection and appropriate treatment improve the survival rate. On both counts the pleural mesothelioma patients are at a disadvantage. Symptoms take anywhere between 20 to 50 years to manifest. Because of this, the patients are generally in the fifty plus age group. And the outwardly noticed indications of the sickness are similar to that of several lesser ailments. This makes the diagnosis difficult. Because of all these, by the time the problem is detected, the cancer is likely to have spread. As yet there is no fully effective line of treatment. It is generally accepted that a combination therapy is better than monotherapy. A great deal of research is being done in this area.

A number of studies have been made about the survival rate among pleural mesothelioma patients. They all come to the same conclusion – the disease is almost always fatal. The lifespan of a person diagnosed with pleural mesothelioma is about six months to two years. There have been exceptions and their stories are inspiring. The life expectancy varies according to the stage (pleural mesothelioma has four different phases) and the type. One research based on the histologic (tissue structure)tests shows a median survival of 11 months – 9.4 months for sarcomatous, 12.5 months for epithelial and 11 months for mixed.

Several inspirational books are available for the patient to read and fortify himself. Also helpful are chat rooms with others in the same condition.
