Mesothelioma Types – Peritoneal Mesothelioma

Malignant peritoneal mesothelioma is a rare type of cancer that occurs in the thin cell walls that surround the abdominal cavity, known as the peritoneum. This thin membrane acts as a lubricant within the abdominal cavity to adjacent organs and structures of the inner body may contract and expand within their normal body function.

Other types of cancer including mesothelioma malignant pleural mesothelioma, which occurs in the cell wall surrounding the lungs, and mesothelioma of the pericardium, which occurs in the lining of the pericardium of the heart. Peritoneal mesothelioma is the rarest form of the disease, second and accounts for about 20% of cases of mesothelioma each year.

What causes peritoneal mesothelioma?

Peritoneal mesothelioma is only known to be caused by exposure to asbestos, a natural microscopic fiber that was used heavily in industry. Asbestos is said to reach the abdominal wall by one of two methods. The first is through the ingestion of asbestos fibers that are processed through the digestion and become lodged in the peritoneum. These other method is through the lungs and lymph nodes, inhalation of asbestos fibers. Malignant pleural mesothelioma is also known as metastasis directly into the abdominal cavity, if its spread is not slowed.

Many who worked with asbestos materials developed peritoneal mesothelioma as a result of exposure to asbestos fibers brittle. Asbestos was used in many industrial materials and construction products. Asbestos exposure was common in aluminum plants, steel mills, power plants and shipyards.

Peritoneal mesothelioma is a relatively rare disease, with only 200-500 women per year in the United States to be documented. Risk however, is sustained in those who were exposed to asbestos. Even those exposed many years ago, are potentially at risk for developing malignant peritoneal mesothelioma. Latency between asbestos exposure and the development of peritoneal mesothelioma symptoms can be anywhere from 20-50 years. Misdiagnosis is also common because the symptoms of peritoneal mesothelioma closely mimic minor stomach discomfort / abdominal hernia. However, those with clear history of exposure to asbestos should be aware of the disease and talk with your doctor or cancer specialist if they believe that if they experience symptoms related to mesothelioma.

Peritoneal Mesothelioma How is it treated?

Prognosis of patients with mesothelioma is poor, and patients with peritoneal mesothelioma are no exception. Most forms of treatment of peritoneal mesothelioma patients include methods such as chemotherapy and palliative radiotherapy mesothelioma. However, if the disease is diagnosed in its early stages, patients such as those diagnosed with mesothelioma Phase 1, these individuals may be eligible for surgical resection of the disease, which could add years to the initial predictions.

Surgery is possible for patients diagnosed with earlier stage disease. Some surgical options include pneumonectomy, extra-pleural pneumonectomy, and palliative procedures such as thoracentesis or pleurodesis. Pneumonectomy and extra-pleural pneumonectomy are lengthy procedures involving the removal of not affecting the lung and surrounding structures of the body. Some doctors, including Dr. David Sugarbaker International Mesothelioma Program at Brigham and Women’s Hospital in Boston, MA, have become extremely well versed and experienced in the surgical treatment of malignant mesothelioma. In many cases, surgical treatment for mesothelioma will be combined with chemotherapy or radiotherapy regimes.

Chemotherapy is the most common treatment for the disease of mesothelioma. There has been only one prior chemotherapy regimen (Alimta (pemetrexed) in combination with cisplatin), approved by the Food and Drug Administration as a therapy prescribed for the treatment of malignant pleural mesothelioma. There is, however, dozens of clinical trials being conducted for mesothelioma patients experimenting with new drugs, including gemcitabine, Navelbine, ONCONASE, and others for the treatment of malignant peritoneal mesothelioma.

How Peritoneal Mesothelioma is diagnosed?

Mesothelioma doctors may suspect peritoneal mesothelioma if the patient complains of stomach, chest or abdominal pain. Suspicious hernias can actually be a pleural effusion caused by peritoneal tumor growth. Misdiagnosis is common and patients will undergo multiple imaging studies and probably a biopsy before a diagnosis is made official.

Diagnostic procedures in which fluid is extracted from the peritoneum for lab tests are the only way to conclusively diagnose peritoneal mesothelioma. Samples will be analyzed for the presence of malignant cells. Since malignant cells are detected, further tests are needed to classify these cells as malignant mesothelioma.

What are the options for a patient?

Patients of peritoneal mesothelioma may be eligible for compensation if they are negatively exposed to asbestos. industrial exhibitions were common and are exposed were collected compensation to fund the high costs of treatment.
