Synopsis: Overview of pleural mesothelioma, covering symptoms, stages, and treatment options, with insights into diagnosis challenges and SSA disability recognition.

Why it matters: This report provides a comprehensive overview of pleural mesothelioma, a rare cancer affecting the lining of the chest cavity and lungs. It details risk factors, notably asbestos exposure, and highlights the disease's latency period of 30 to 50 years. The report outlines symptoms such as shortness of breath and chest pain, discusses diagnostic challenges due to symptom similarity with other conditions, and reviews treatment options including surgery, radiation therapy, and chemotherapy. Additionally, it mentions that the U.S. Social Security Administration recognizes pleural mesothelioma as a Compassionate Allowance, expediting disability claims for affected individuals - Disabled World (DW).

Introduction

Pleural Mesothelioma is a rare type of cancer in which malignant cells are found in the pleura (the thin layer of tissue that lines the chest cavity and covers the lungs).

The U.S. Social Security Administration (SSA) has included Pleural Mesothelioma as a Compassionate Allowance to expedite a disability claim.

Main Item

Exposure to airborne asbestos particles increases one's risk of developing malignant mesothelioma. Although reported incidence rates have increased in the past 20 years, mesothelioma remains a relatively rare cancer.

About 2,000 new mesothelioma cases are diagnosed annually in the United States.

Mesothelioma occurs more often in men than in women, and risk increases with age, but this disease can appear in either men or women at any age.

Working with asbestos is the major risk factor for mesothelioma. A history of asbestos exposure at work is reported in about 70 percent to 80 percent of all cases. However, mesothelioma has been reported in some individuals without known exposure to asbestos.

Symptoms of mesothelioma may not appear until 30 to 50 years after asbestos exposure. Shortness of breath and pain in the chest due to an accumulation of fluid in the pleura are often symptoms of pleural mesothelioma.

Diagnosing pleural mesothelioma is often difficult because the symptoms are similar to those of several other conditions.

Diagnosis begins with a review of the patient's medical history, including any history of asbestos exposure. A complete physical examination may be performed, including x-rays of the chest or abdomen and lung functioning tests. A CT scan or an MRI may also be useful.

A biopsy is needed to confirm a diagnosis of pleural mesothelioma. In a biopsy, a surgeon or medical oncologist (a doctor specializing in diagnosing and treating cancer) removes a tissue sample for examination. The doctor may perform a thoracoscopy if the cancer is in the chest. In this procedure, the doctor makes a small cut through the chest wall and puts a thin, lighted tube called a thoracoscope into the chest between two ribs. Thoracoscopy allows the doctor to look inside the chest and obtain tissue samples. More extensive diagnostic surgery may be necessary if the procedure does not yield enough tissue.

Treatment for pleural mesothelioma depends on cancer's location, the tumor's size, the amount of fluid in the chest, the stage of the disease, and the individual's age and general health. Standard treatment options include surgery, radiation therapy, and chemotherapy. Surgery is associated with a median survival time of 15-24 months; chemotherapy has an average response rate of 10-20%.

Pleural mesothelioma patients who undergo lung-sparing surgery in combination with photodynamic therapy (PDT) show superior overall survival than patient treated using the conventional therapy of extrapleural pneumonectomy (EPP) (or en bloc removal of the lung and surrounding tissue) with PDT - Pleural Mesothelioma Combination Therapy Shows Promise

Advanced malignant mesothelioma includes stages II, III, and IV.

Insights, Analysis, and Developments

Editorial Note: The inclusion of pleural mesothelioma in the SSA's Compassionate Allowance program underscores the severity of this disease and the importance of timely support for those affected. This recognition facilitates quicker access to disability benefits, providing crucial assistance to patients and their families during challenging times - Disabled World (DW).
