Pleural Mesothelioma: Know the Symptoms, Causes and Treatment Solutions

Understanding Pleural Mesothelioma, a rare and aggressive form of cancer, is crucial for anyone who may be at risk or is currently dealing with this disease. With a focus on the lining of the lungs, known as the pleura, pleural mesothelioma poses unique challenges in terms of diagnosis and treatment.

What is Malignant Pleural Mesothelioma?

Malignant pleural mesothelioma is a cancer that affects the pleura, the thin membrane surrounding the lungs. It is primarily linked to asbestos exposure, and although asbestos use has declined, cases of pleural mesothelioma are still being diagnosed due to the long latency period of the disease, which can range from 20 to 50 years.

Causes of Pleural Mesothelioma

The principal cause of pleural mesothelioma is prolonged exposure to asbestos fibers. When inhaled, these fibers can lodge in the pleura, leading to inflammation and genetic damage over time. This damage can eventually cause malignant transformations in the pleural cells. While occupational exposure remains the most common risk factor, secondary exposure can occur among family members of workers who handled asbestos.

Symptoms of Pleural Mesothelioma

Early Symptoms

Pleural mesothelioma symptoms often resemble those of other respiratory conditions, making early diagnosis challenging. Initial symptoms may include persistent dry cough, shortness of breath, and chest pain. These symptoms are often mistaken for pneumonia or bronchitis, leading to delays in accurate diagnosis.

Progressive Symptoms

As the disease progresses, symptoms intensify and diversify. Patients may experience severe chest pain, significant weight loss, night sweats, and fever. Additionally, pleural effusion, an accumulation of fluid in the pleural space, is a common symptom that exacerbates breathing difficulties.

Diagnosing Pleural Mesothelioma

Imaging Tests

Diagnosis typically begins with imaging tests such as X-rays, CT scans, and MRIs to identify abnormalities in the pleura. These tests help in visualizing the extent of disease spread and are crucial for planning further diagnostic procedures.

Biopsy Procedures

A definitive diagnosis of pleural mesothelioma requires a biopsy, where tissue samples are extracted from the pleura for microscopic examination. Procedures like thoracoscopy allow for direct visualization of the pleura and collection of tissue, providing essential information for an accurate diagnosis.

Treatment Options for Pleural Mesothelioma

Surgery

Surgical intervention aims to remove as much of the tumor as possible. Procedures like pleurectomy/decortication (P/D) and extrapleural pneumonectomy (EPP) are considered based on the stage of the disease and the patient’s overall health. While surgery can improve symptoms and potentially prolong survival, it is typically part of a multimodal approach.

Chemotherapy

Chemotherapy uses potent drugs to target and destroy cancer cells. In pleural mesothelioma, chemotherapy is often administered systemically or directly into the pleura to maximize effectiveness. The combination of pemetrexed and cisplatin is a standard regimen, aiming to shrink tumors and alleviate symptoms.

Radiation Therapy

Radiation therapy focuses high-energy beams on cancer cells to kill them or inhibit their growth. It is often used in conjunction with surgery or chemotherapy to enhance treatment efficacy. While it can be effective in controlling localized disease, care must be taken to minimize damage to surrounding healthy tissue.

Emerging Treatments and Clinical Trials

Research into pleural mesothelioma is ongoing, with clinical trials exploring innovative treatments such as immunotherapy and targeted therapy. Immunotherapy aims to harness the patient’s immune system to fight cancer, while targeted therapy seeks to attack specific molecules involved in cancer growth. Participation in clinical trials offers access to cutting-edge treatments and contributes to advancing medical knowledge.

Preventing Pleural Mesothelioma

Reducing Asbestos Exposure

Prevention of pleural mesothelioma primarily involves minimizing exposure to asbestos. This entails adhering to safety regulations in workplaces where asbestos is present and ensuring proper asbestos removal procedures in older buildings. Awareness campaigns and regulatory measures have significantly reduced exposure risks in recent decades.

Regular Health Monitoring

For individuals with known asbestos exposure, regular health monitoring is essential. This includes periodic imaging and lung function tests to detect any abnormalities early. Early detection can lead to more effective management of the disease and better outcomes.
