Pleural Mesothelioma
Pleural mesothelioma is a rare and aggressive cancer that affects the lining of the lungs, known as the pleura. It is primarily caused by exposure to asbestos fibers, which can become trapped in the lungs and lead to the development of cancerous cells. Common symptoms of pleural mesothelioma include chest pain, shortness of breath, coughing, and fatigue. Treatment options for pleural mesothelioma may include surgery, chemotherapy, and radiation therapy, as well as various clinical trials and experimental therapies.
What Causes Pleural Mesothelioma?
Pleural mesothelioma is primarily caused by exposure to asbestos fibers, which are tiny mineral fibers that can become airborne and inhaled into the lungs. Once inhaled, the fibers can become trapped in the lining of the lungs, known as the pleura, and over time, can cause genetic mutations and cellular damage that lead to the development of cancerous cells. Other risk factors for pleural mesothelioma may include a family history of the disease, exposure to other environmental toxins, and certain genetic mutations. However, asbestos exposure is by far the most common cause of pleural mesothelioma.
Who Is At Risk?
Those who have been exposed to asbestos, either in their work or in their environment, are at the highest risk of developing pleural mesothelioma. Workers in certain industries, such as construction, shipbuilding, and manufacturing, are particularly at risk due to the widespread use of asbestos in these fields prior to its regulation in the 1970s. Additionally, family members of individuals who work with asbestos may also be at risk due to secondhand exposure. Other risk factors for pleural mesothelioma may include a history of radiation therapy to the chest, certain genetic mutations, and a family history of the disease.
Several professions have a high risk of exposure to asbestos, which can increase the risk of developing pleural mesothelioma. These professions include:
- Construction Workers, especially those involved in insulation, roofing, and building demolition.
- Shipyard Workers who build or repair ships and naval vessels.
- Manufacturing Workers who produce or handle asbestos-containing products, such as insulation, gaskets, and textiles.
- Railroad Workers who work with asbestos-containing brakes and insulation.
- Automotive Mechanics who repair brakes and clutches that contain asbestos.
- Miners who work in asbestos mines or in close proximity to asbestos deposits.
- Military Veterans who served on ships or in construction projects during times when asbestos was commonly used.
These are just a few examples, but many other professions and industries may also pose a risk of exposure to asbestos and an increased risk of pleural mesothelioma.
Symptoms of Pleural Mesothelioma
The symptoms of pleural mesothelioma can vary depending on the stage and progression of the cancer, but some common symptoms include:
- Chest pain or discomfort, often accompanied by difficulty breathing
- Persistent cough or hoarseness
- Fatigue or weakness
- Unexplained weight loss
- Shortness of breath, even at rest
- Fluid buildup in the chest cavity (pleural effusion)
- Difficulty swallowing (dysphagia)
- Night sweats or fever
- Swelling in the face and arms
- Muscle weakness and sensory loss (neurological symptoms)
It’s important to note that these symptoms can be caused by a variety of conditions, and having these symptoms does not necessarily mean you have pleural mesothelioma. However, if you have a history of asbestos exposure or other risk factors, it’s important to speak with your healthcare provider if you experience any of these symptoms. Early detection and treatment can improve outcomes for people with pleural mesothelioma.
Pleural Plaques
Pleural plaques are a type of lung condition that can be caused by exposure to asbestos fibers. They are essentially areas of scarring or thickening of the pleural membrane, which is the thin layer of tissue that lines the outside of the lungs and the inside of the chest cavity. Pleural plaques are not cancerous and typically do not cause any symptoms, but they can be an indicator of past exposure to asbestos.
Pleural plaques can often be seen on chest X-rays or CT scans and can be an important piece of information for healthcare providers when assessing a patient’s risk for asbestos-related diseases, such as pleural mesothelioma. While pleural plaques themselves are not harmful, their presence indicates a history of asbestos exposure, which can increase the risk of developing more serious lung conditions in the future.
Pleural Effusion
Pleural effusion is a condition that can occur when fluid accumulates in the pleural cavity, which is the space between the pleural membrane that lines the outside of the lungs and the inside of the chest cavity. This condition can be caused by a variety of factors, including pleural mesothelioma, congestive heart failure, pneumonia, and other lung infections.
The buildup of fluid in the pleural cavity can put pressure on the lungs and make it difficult to breathe. Common symptoms of pleural effusion include shortness of breath, chest pain, coughing, and fatigue. Treatment for pleural effusion depends on the underlying cause, but may include draining the fluid from the pleural cavity using a needle or chest tube, treating the underlying condition, or medications to help manage symptoms.
If you have symptoms of pleural effusion, it’s important to speak with your healthcare provider to determine the underlying cause and develop an appropriate treatment plan.
Pleural Thickening
Pleural thickening is a lung condition that can be caused by exposure to asbestos fibers. It occurs when the pleural membrane, which is the thin layer of tissue that lines the outside of the lungs and the inside of the chest cavity, becomes thicker and less flexible. Pleural thickening can cause breathing difficulties and may lead to other serious lung conditions, including pleural mesothelioma.
Symptoms of pleural thickening may include shortness of breath, chest pain, and persistent cough. Diagnosis typically involves a physical exam, imaging tests such as a chest X-ray or CT scan, and pulmonary function tests to assess lung function.
Treatment for pleural thickening depends on the severity of the condition and may include medications to manage symptoms, breathing exercises, and in some cases, surgery to remove the thickened tissue. It’s important to note that pleural thickening can be a sign of past exposure to asbestos, and individuals who have been exposed to asbestos should be monitored regularly for any potential lung complications.
Asbestosis
Asbestosis is a chronic lung disease caused by prolonged exposure to asbestos fibers. When asbestos fibers are inhaled, they can become lodged in the lungs and cause scarring, which can lead to difficulty breathing and other respiratory problems. Unlike pleural plaques or pleural thickening, asbestosis is a serious and potentially life-threatening condition.
Symptoms of asbestosis can include shortness of breath, persistent cough, chest pain, and fatigue. Diagnosis is typically made through imaging tests such as a chest X-ray or CT scan, as well as pulmonary function tests to assess lung function.
While there is no cure for asbestosis, treatment may include medications to manage symptoms, oxygen therapy to help with breathing, and in some cases, pulmonary rehabilitation to improve lung function. It’s important for individuals who have been exposed to asbestos to be monitored regularly by their healthcare provider and to take steps to minimize further exposure to asbestos.
How Pleural Mesothelioma Is Diagnosed?
Diagnosing pleural mesothelioma can be challenging because its symptoms are similar to those of other lung conditions. However, several diagnostic tests and procedures can be used to help confirm a diagnosis of pleural mesothelioma.
First, a healthcare provider will typically take a detailed medical history and conduct a physical exam to assess symptoms and overall health. Imaging tests such as a chest X-ray, CT scan, or MRI may also be ordered to look for signs of pleural thickening, pleural effusion, or other abnormalities in the chest.
If imaging tests suggest the presence of pleural mesothelioma, a tissue biopsy may be performed to confirm the diagnosis. This involves taking a small sample of tissue from the affected area of the lung or pleura and examining it under a microscope for signs of mesothelioma cells.
Other tests, such as blood tests or pulmonary function tests, may also be used to assess lung function and overall health.
It’s important to note that diagnosing pleural mesothelioma can be complex, and a healthcare provider may need to consult with specialists in oncology, radiology, and pathology to make an accurate diagnosis. Early detection is important for successful treatment, so individuals who have been exposed to asbestos or who are experiencing symptoms should speak with their healthcare provider as soon as possible.
Cell Types
There are three main cell types of pleural mesothelioma: epithelioid, sarcomatoid, and biphasic.
Epithelioid Mesothelioma is the most common cell type, accounting for approximately 70% of cases. These cells are typically round or cube-shaped and form clusters. They tend to grow more slowly than other cell types and are associated with a better prognosis.
Sarcomatoid Mesothelioma, on the other hand, is more aggressive and less common, accounting for approximately 10-20% of cases. These cells are long and spindle-shaped and can appear similar to other types of cancer cells, making them more difficult to diagnose.
Biphasic Mesothelioma is a combination of both epithelioid and sarcomatoid cell types, accounting for approximately 20-30% of cases. These tumors can be more challenging to treat because they have both slow-growing and more aggressive cell types.
The specific cell type of pleural mesothelioma can impact the course of the disease and the effectiveness of treatment options. A healthcare provider may use a biopsy to determine the cell type and develop an appropriate treatment plan.
Staging
Staging is a process used to describe the extent of cancer and its spread in the body. For pleural mesothelioma, staging is typically based on the TNM system, which stands for tumor size and location, lymph node involvement, and metastasis (spread) to other parts of the body.
The stages of pleural mesothelioma are as follows:
- Stage 1: The cancer is localized to one side of the chest and has not spread to nearby lymph nodes or other parts of the body.
- Stage 2: The cancer has spread to nearby lymph nodes, but is still contained within one side of the chest.
- Stage 3: The cancer has spread to nearby organs or tissues within the chest, such as the heart or lungs, and may have spread to lymph nodes on the opposite side of the chest.
- Stage 4: The cancer has spread extensively to other parts of the body, such as the liver, brain, or bones.
Determining the stage of pleural mesothelioma is important in determining the most appropriate treatment plan, as well as the prognosis for the individual. A healthcare provider may use a combination of imaging tests, such as CT scans and PET scans, as well as biopsy results to stage the cancer.
Pleural Mesothelioma Treatment Options
The treatment options for pleural mesothelioma depend on several factors, including the stage of the cancer, the cell type, the patient’s overall health, and their personal preferences. Some common treatment options include:
- Surgery: Surgery may be recommended to remove the cancerous tissue, particularly if the cancer is localized and has not spread to other parts of the body. Types of surgery may include pleurectomy and decortication (P/D), which removes the pleural lining and any visible tumors, or extrapleural pneumonectomy (EPP), which removes the entire lung and surrounding tissue.
- Radiation Therapy: Radiation therapy uses high-energy radiation to kill cancer cells and may be used before or after surgery, or as a stand-alone treatment for patients who are not eligible for surgery. It can help shrink tumors and alleviate symptoms.
- Chemotherapy: Chemotherapy involves using drugs to kill cancer cells and may be used alone or in combination with surgery or radiation therapy. It can help slow the progression of the cancer and alleviate symptoms.
- Immunotherapy: Immunotherapy drugs help the body’s immune system to recognize and attack cancer cells. This treatment may be used alone or in combination with other treatments and is generally reserved for patients with advanced disease.
- Palliative Care: Palliative care focuses on managing symptoms and improving the quality of life for patients with advanced cancer. It may include pain management, nutritional support, and other supportive therapies.
Treatment for pleural mesothelioma is generally a multimodal approach, meaning that a combination of treatments may be used to achieve the best outcome. Your healthcare provider can work with you to develop a personalized treatment plan based on your individual needs and circumstances.

Pleural Mesothelioma Prognosis and Survival Rates
The prognosis for pleural mesothelioma is generally poor, as it is an aggressive and rare cancer. However, the survival rates can vary depending on several factors, such as the stage of the cancer, the age and overall health of the patient, and the treatment plan.
According to the American Cancer Society, the 5-year survival rate for people with mesothelioma is around 20% for all stages combined. However, this statistic varies widely based on the stage of the cancer at diagnosis. For example, the 5-year survival rate for stage 1 pleural mesothelioma is around 40%, whereas the 5-year survival rate for stage 4 pleural mesothelioma is only around 5%.
It’s important to note that survival rates are just estimates and may not accurately predict an individual’s outcome. Additionally, advancements in treatment options and ongoing research may improve survival rates in the future.
Factors that Affect Your Prognosis
Several factors can affect the prognosis of pleural mesothelioma. These factors include:
- Stage of Cancer: The stage of cancer at diagnosis is one of the most important factors affecting prognosis. The earlier the stage, the better the prognosis.
- Cell Type: The cell type of the mesothelioma can also affect prognosis. Epithelioid mesothelioma tends to have a better prognosis than sarcomatoid or biphasic mesothelioma.
- Patient Age and Overall Health: Patients who are younger and in good health may have a better prognosis than those who are older or have other underlying health conditions.
- Gender: Women tend to have a better prognosis than men with mesothelioma, although the reason for this is not fully understood.
- Treatment Plan: The type and effectiveness of treatment can also affect prognosis. Patients who undergo surgery, chemotherapy, and/or radiation therapy may have a better prognosis than those who do not receive treatment or receive palliative care.
It’s important to discuss your individual prognosis with your healthcare team, as they can provide more personalized information based on your specific circumstances.
