mesothelioma peritoneum
Peritoneal MesotheliomaPeritoneal mesothelioma is a form of cancer that forms in the peritoneum (the tissue lining of the abdomen). It is caused by inhaling or swallowing asbestos fibers. Patients with this condition may survive several years after diagnosis.

| mesothelioma peritoneum |
Peritoneal mesothelioma is the second-most common type of mesothelioma.
Tumors of this rare asbestos-related cancer form on the abdominal lining.
The beginning symptoms of peritoneal mesothelioma include abdominal distension, abdominal pain, swelling or tenderness around the abdomen and constipation or diarrhea.
Important Facts About Peritoneal Mesothelioma
It accounts for less than 20 percent of all mesothelioma cases.
Surgery and heated chemotherapy are the most effective treatments.
Immunotherapy for this type is available through clinical trials.
Peritoneal patients generally live four times longer than pleural mesothelioma patients.
The survival rate of someone diagnosed with peritoneal mesothelioma depends on the stage of the cancer, types of treatments the patient undergoes and the quality of the specialist treating the patient.
Surgery plays a major role in long-term survival. Patients who don’t qualify for surgery live around one year. About half of patients who undergo surgery and heated chemotherapy are alive more than five years later.
Although clinical trials for peritoneal mesothelioma are not as abundant as those for pleural mesothelioma, researchers are studying whether immunotherapy combined with chemotherapy could play a bigger role in controlling the cancer by boosting the body’s immune system
Mesothelioma in the Peritoneum
The peritoneum is a protective membrane with two layers that surrounds the abdomen. Peritoneal mesothelioma can develop on both layers.
Parietal layer: Covers the abdominal cavity.
Visceral layer: Surrounds the stomach, liver and other organs of the abdomen.
Together, the layers support the abdominal cavity and its organs.
What Causes Peritoneal Mesothelioma?
Asbestos exposure is the primary cause of peritoneal mesothelioma, also known as abdominal mesothelioma.
Development of Peritoneal Mesothelioma
Swallowed asbestos fibers travel from digestive system to the peritoneum.
Inhaled asbestos fibers travel from lymphatic system to the peritoneum.
Once fibers are in the peritoneum, they irritate the cells.
The irritated cells begin to thicken the peritoneal lining.
Excess abdominal fluid builds.
Over time, tumors begin to form on the damaged peritoneum.
Research on other causes of abdominal mesothelioma is scarce. Evidence shows other fibrous minerals, such as erionite, and radiation to the abdomen trigger some cases of this disease.
