What is Well Differentiated Papillary Mesothelioma of the Peritoneum?
Well differentiated papillary mesothelioma of the peritoneum (WDPM) is a rare tumor that originates in the mesothelial lining of the peritoneal cavity. It is a subtype of mesothelioma, a type of cancer that is usually associated with asbestos exposure. Unlike other types of mesothelioma, WDPM is not related to asbestos exposure and can affect both men and women of any age. WDPM is characterized by the presence of papillary structures that resemble the villi of the small intestine.
Although WDPM is considered an indolent and non-aggressive tumor, it has the potential to recur and spread to other organs. The diagnosis of WDPM is often challenging, as it can mimic other benign or malignant conditions. Most patients diagnosed with WDPM undergo surgical resection, and the prognosis is generally excellent, with a high rate of disease-free survival, even in cases of recurrence.
The Symptoms and Diagnosis of WDPM
The symptoms of WDPM are often nonspecific and can include abdominal pain, bloating, nausea, vomiting, and weight loss. As these symptoms are common to many other conditions, the diagnosis of WDPM can be challenging, and a detailed medical history, physical examination, and diagnostic imaging tests are necessary.
The diagnosis of WDPM requires a biopsy of the peritoneal tissue. The biopsy can be performed either by laparoscopy or laparotomy. The tissue sample is then examined under a microscope to determine whether it is WDPM or another condition. The confirmation of WDPM requires the identification of papillary structures in the tissue sample.
How is WDPM Treated?
The optimal treatment for WDPM is surgical resection. The extent of surgery depends on the location and size of the tumor. If the tumor is localized, a complete resection may be possible, which is associated with an excellent prognosis. In cases where a complete resection is not possible, debulking surgery or cytoreductive surgery may be recommended. These procedures aim to remove as much of the tumor as possible to minimize the risk of recurrence.
Chemotherapy and radiotherapy have not been shown to be effective in the treatment of WDPM. However, these treatments may be used in conjunction with surgery in certain cases, such as when there is residual disease after surgery or if the tumor is inoperable.
