Although peritoneal mesothelioma is the most common of these, it is rare with an annual incidence of 1-2 cases per million persons. Only 10-20 percent of all mesotheliomas arise in the peritoneum. Peritoneal malignant mesothelioma occurs more often in adult males but also occurs seldom in children with equal sex incidence.
Mesothelioma tumors of the peritoneum include benign, malignant and cystic.
Cause-Multicystic Peritoneal Mesothelioma
The link with asbestos exposure which is well established for pleural mesothelioma is not clear for peritoneal mesothelioma.
Malignant mesothelioma occurs chiefly late in the fifth decade of life, the benign type in the fourth decade and the cystic type in the third decade. The non malignant type are common in ladies.
Signs and Signs-Multicystic Peritoneal Mesothelioma
-Abdominal pain which may not be limited to any specific region of the abdomen but may be migratory.
-Abdominal distention and complaints associated with partial bowel obstruction are frequent
-Ascites (liquid in the abdomen,) may be present
-Abdominal mass/swelling may be present
Diagnosis-Multicystic Peritoneal Mesothelioma
-CT scans often show tumor masses and ascites (liquid in the abdomen)
-Laparatomy and laparoscopy for multiple biopsies the surgeon opens up the abdomen surgically to look in to the peritoneum directly and take samples
Prognosis of Peritoneal Mesothelioma
The prognosis of peritoneal mesothelioma is dismal with median survival of about one year after presentation. Death usually results from progressive bowel obstruction.
Treatment of Peritoneal Mesothelioma-Multicystic Peritoneal Mesothelioma
It is treated with combination therapy:
A. Peritoneal radioactive P32 followed by whole abdomen radiation is used often
B. Chemotherapy:Combination chemotherapy with doxorubicin is a important secondary part.
C. Surgical procedure:Surgical treatment is completed chiefly to debulk (reduce the size of the tumor by cutting of parts of the tumor,) and treatment of intestinal obstruction.
