Understanding Metastatic Pleural Mesothelioma | Symptoms, Treatment, and Prognosis


Mesothelioma is a rare and aggressive cancer that primarily affects the lining of the lungs, known as the pleura. It is caused by exposure to asbestos fibers, which were once commonly used in building materials due to their fire-resistant properties. This deadly disease can also spread to other areas of the body, such as the abdomen, heart, and lymph nodes, making it even more difficult to treat. When the cancer spreads beyond the original site, it is known as metastatic pleural mesothelioma.

In this article, we will explore the complex world of metastatic pleural mesothelioma, including its causes, symptoms, diagnosis, treatment options, and prognosis. We will also discuss the challenges faced by patients living with this disease and the latest research developments that offer hope for better treatment options in the future.

What is Metastatic Pleural Mesothelioma?

Metastatic pleural mesothelioma occurs when primary mesothelioma cancer cells break away from the original tumor in the pleura and travel to other organs or tissues in the body. This type of cancer is considered advanced because it has spread beyond its initial location and is more challenging to treat. The most common sites for metastasis in pleural mesothelioma include the lungs, liver, bones, and brain.

The exact mechanism of how mesothelioma cells metastasize is not fully understood. However, researchers believe that it may be due to the cancer cells’ ability to secrete enzymes that allow them to invade nearby tissues and enter the bloodstream or lymphatic system. From there, they can travel to distant locations and form new tumors, further complicating the disease and reducing a patient’s chances of survival.

Symptoms of Metastatic Pleural Mesothelioma


The symptoms of metastatic pleural mesothelioma are similar to those of primary mesothelioma, but they may be more severe due to the spread of cancer to other areas of the body. Common symptoms include:

  • Shortness of breath
  • Chest pain or discomfort
  • Persistent cough
  • Fatigue
  • Unexplained weight loss
  • Difficulty swallowing
  • Abdominal pain or swelling
  • Nausea and vomiting
  • Changes in bowel habits

These symptoms can vary depending on the location of the metastases. For example, if the cancer has spread to the brain, a patient may experience headaches, seizures, or changes in their cognitive abilities. If the liver is affected, it can cause jaundice (yellowing of the skin and eyes), abdominal pain, and swelling.

It is essential to note that these symptoms can also be caused by other medical conditions, so it is crucial to seek medical attention if you are experiencing any of them, especially if you have a history of asbestos exposure.

Diagnosis of Metastatic Pleural Mesothelioma


Diagnosing metastatic pleural mesothelioma is often challenging because the cancer has already spread beyond its original location. It requires multiple tests and imaging scans to determine the extent of the disease and identify the sites of metastasis accurately. These may include:

  • X-rays: Can detect abnormalities in the lungs and other organs.
  • CT scan: Provides a more detailed image of the lungs and possible tumors.
  • MRI: Produces high-resolution images of soft tissues, such as the pleura and surrounding structures.
  • PET scan: Shows areas of increased metabolic activity, which can indicate the presence of cancer.
  • Biopsy: A tissue sample is taken from an affected organ or lymph node and examined under a microscope to confirm the presence of cancer cells.

Once a diagnosis is made, further testing may be required to determine the stage of cancer and the best treatment approach.

Treatment Options for Metastatic Pleural Mesothelioma

The treatment for metastatic pleural mesothelioma is similar to that of primary mesothelioma, with the goal of managing symptoms and slowing the spread of cancer. However, because the cancer has already spread, treatment options may be more limited.

Surgery: Surgery is often not an option for patients with metastatic pleural mesothelioma as the cancer has spread to multiple areas of the body. However, in some cases where a solitary metastasis is present, surgery may be considered to remove as much of the tumor as possible.

Chemotherapy: Chemotherapy drugs are used to destroy cancerous cells and slow the progression of the disease. This treatment can be delivered intravenously or directly into the affected area (intracavitary chemotherapy). It can also be used in combination with other treatments, such as surgery or radiation therapy.

Radiation therapy: This treatment uses high-energy X-rays to target and kill cancer cells. It can be administered externally (external beam radiation) or through an internal source placed inside the body near the tumors (brachytherapy).

Immunotherapy: This treatment works by stimulating the body’s immune system to recognize and fight cancer cells. It has shown promising results in some patients with advanced mesothelioma.

Palliative care: For patients with late-stage metastatic pleural mesothelioma, palliative care is essential to manage symptoms and improve their quality of life. This may include pain management, breathing support, and emotional and psychological support for both the patient and their loved ones.

Prognosis and Survival Rates

Unfortunately, the prognosis for patients with metastatic pleural mesothelioma is poor. The average survival time is around 12 months, but this can vary depending on individual factors such as age, overall health, and the location and extent of metastases.

According to the American Cancer Society, the five-year survival rate for all stages of mesothelioma is only 10%, with most cases being diagnosed at advanced stages. However, research and advancements in treatment are offering hope for better outcomes in the future.


Metastatic pleural mesothelioma is a devastating disease that can greatly impact a patient’s quality of life. It is caused by exposure to asbestos fibers and can spread to other areas of the body, making it challenging to treat. Early detection and proper treatment can improve a patient’s chances of survival, but more research is needed to develop effective therapies for advanced stages of this cancer. If you or your loved ones have a history of asbestos exposure and are experiencing symptoms, seek medical attention immediately. With ongoing research and awareness, there is hope for better treatment options and improved outcomes for those living with metastatic pleural mesothelioma.
