Well Differentiated Papillary Mesothelioma Treatment
Papillary mesothelioma that is well differentiated occurs mostly in the abdomen’s lining, called the peritoneum. It can also occur in the pleura that surrounds the lungs and in the tunica vulginalis of testes.
Mesothelioma can be a deadly disease, however this type has low malignant potential and typically responds to treatment. It can recur and can progress to a more advanced form of cancer.
Symptoms
Papillary mesothelioma which is well differentiated develops on the membranes surrounding various organs. It most often occurs in the peritoneum, however it can also appear on the pleura (lining around the lung) as well as the pericardium (a sac that is located around the heart) and the tunica vaginalis (the liner of the testicles). While mesothelioma is generally a cancerous condition, some types are benign. These are mesotheliomas of low grade that usually have a better prognosis than mesothelioma that is malignant.
Asbestos is the most common cause mesothelioma. In certain cases asbestos exposure may cause symptoms that manifest several years later. Therefore, doctors must diagnose the condition through an examination of the body and taking blood samples to test for the condition. They use imaging technology like x rays MRIs, and PET scans to look for symptoms of mesothelioma.
Treatment for mesothelioma can be most efficient when the tumors are identified and treated early, prior to their progression into malignant forms. Therefore, many mesothelioma specialists recommend routine follow-ups to detect any possible changes. However a case report published in the Journal of Medical Ultrasound showed that regular imaging follow-ups might not be required for patients with well differentiated mesothelioma papillary.
The report reviewed an instance of WDPM which was diagnosed in combination with a struma Ovarian. This is a rare tumor located in the serosal tissues that surround the uterus. The patient was experiencing abdominal pain accompanied by a painful debulking laparoscopy. The pathology that resulted revealed a non-invasive papillary proliferation of mesothelial cells with retained labelling for BAP1 – considered appropriate under the latest WHO classification.
According to the study, WDPM is benign tumor that rarely develops into mesothelioma that is invasive. The authors of the study note that epithelioid mesotheliomas with invasive epitheli are clear can also resemble WDPM.
Diagnosis
In many instances, abdominal pain and swelling are the first signs. The condition can also cause an accumulation of fluid in the lungs or abdomen. It is important that you get a diagnosis by an expert doctor. Mesothelioma is classified as epithelial, sarcomatoid, or biphasic. WDPM unlike mesothelioma malignancy that can quickly spread to other parts of the human body, is generally benign.
The majority of mesotheliomas can be classified according to their cell type. The most prevalent type is epithelial, and the most rare is sarcomatoid. However, a few studies have examined the possibility that mesothelioma could develop into a well-differentiated mesothelioma that is papillary. Although sarcomatoid mesothelioma comes with a very poor prognosis, a well-differentiated mesothelioma is considered to have a low-risk.
In the past there were only 14 cases of well-differentiated papillary melanoma in the medical literature. This rare tumor forms in the lining of certain organs, including the pleura and the peritoneum. The exact cause is not known however it is believed that exposure to asbestos is the cause.
The WDPM tumor is located in the lining of the organ it targets, which is usually the peritoneum. It can also develop in the pleura (the sac that surrounds lungs) and tunica vaginalis, which is the testes’ tunica vaginalis.
WDPM is considered mesothelioma with low-grade grade, but it has the potential to transform into malignant mesothelioma in time. Some patients have developed malignant mesothelioma and WDPM in the same spot within their bodies.
Doctors diagnose WDPM using a sample of affected tissue. They then perform tests in the laboratory on the sample. These tests check for the presence of cancerous cells as well as the degree of differentiation of those cells. If the patient is diagnosed with this disease, they should have regular follow-up appointments to ensure that the tumor doesn’t grow or become recurrent. WDPM could be misdiagnosed as a different condition or misinterpreted as benign mesothelioma, so it is crucial that doctors are aware of the rare nature of this tumor and the possibility of it recurring. If this condition recurs, you should consult an experienced mesothelioma lawyer to discuss your options.
Treatment
Treatment of papillary mesothelioma with a differentiated approach is typically effective and provides an improved prognosis when than other mesothelioma types. However, like other mesothelioma types, patients will need to see an expert doctor to ensure the correct diagnosis and the best treatment options.
The first step in mesothelioma treatment is surgically removing the cancerous or tumor-causing tissue from the affected part of the body. The surgeon may also use radiation therapy or chemotherapy to kill any remaining cancerous cells and prevent the development of new tumors in the future.
Doctors have also found mesothelioma in other parts of body, such as the pericardium and tunica vaginalis, and pleura. In the case of WDPMT the tumors are typically seen as white to gray nodules that are about one to three centimeters in diameter. The tumors grow slowly but they can cause swelling and pain as they grow.
The cell structure of papillary mesothelioma that is well-differentiated is unique, and it distinguishes it from other types of mesothelioma. The tumors exhibit branches of cuboidal mesothelial cells that form finger-like projections known as papillae. The papillae are usually located in the peritoneal lining however, they can also be found in the pleura as well as testicles.
Despite their distinct cellular structures, epithelial mesothelioma (WDPM) and other types must be carefully distinguished from malignant sarcomatoid mesothelioma that has a more invasive course of action. Sarcomatoid cells of mesothelioma are more likely than other mesothelioma types to grow rapidly and spread widely.
In addition, sarcomatoid mesothelioma is more likely to be related to smoking and less likely to be affected by asbestos exposure than other mesothelioma cancer kinds. The connection between asbestos exposure and mesothelioma is not yet clear. Asbestos may contribute to the development both of benign and malignant forms of mesothelioma. However, it does not appear to be the cause of WDPM. WDPM that is isolated can develop into mesothelioma that is malignant. However, it is unclear which patients are at highest risk. There is a higher chance of a more aggressive course for those who’s solitary WDPM has a decrease in the proteins BAP1 and MTAP.
The following is a list with preventions.
Papillary mesothelioma can be found most commonly in the abdomen’s lining (peritoneum) and less often in the linings of the lungs and testicles. This epithelial mesothelioma subtype is generally benign and has a good prognosis. However, a small possibility of transformation into malignant mesothelioma remains. This cancer is believed by experts to be caused by asbestos, which is a carcinogen. But, researchers continue to look into possible causes.
In some cases, WDPM can transform into malignant mesothelioma of the pleural. This is a rare situation. However it is essential that you seek treatment and diagnosis as quickly as you can if you notice any of the symptoms.
WDPM and Sarcomatoid Mesothelioma are two separate types of malignant tumors that differ from one other in their cell structure and prognosis. WDPM is generally epithelial while sarcomatoid is more often a sarcomatoid type of tumor. malignant mesothelioma treatment can be found and may have both epithelial as well as sarcomatoid characteristics.
Because WDPM is generally benign, this type of mesothelioma generally has a better chance of survival than other malignancy types. This is especially true when it is detected in the peritoneum. It can still cause significant health issues and is difficult to treat if it occurs in the tunica vaginalis or pleura.
Typically doctors will diagnose this kind of mesothelioma if it is found during surgery for a different condition or in a patient who has abdominal pain and/or fluid buildup. A biopsy is needed to confirm the diagnosis.
Patients who have a history of asbestos exposure should be assessed and treated by a mesothelioma specialist who is up-to-date on the latest research. Patients have reported survival rates of up to 60 percent when paired with aggressive locoregional treatments, including cytoreductive surgical removal of all gross disease, and hyperthermic intraperitoneal chemotherapy to eradicate microscopic disease. This is far greater than the average survival rate of the historical controls. Because of this, it is crucial to seek treatment at a mesothelioma-referral center.
