What Is Sarcomatoid Mesothelioma?

Sarcomatoid mesothelioma is a rare form of mesothelioma that accounts for approximately 10-15% of all mesothelioma cases. This type of mesothelioma is characterized by the presence of spindle-shaped cells that resemble sarcoma, a type of cancer that affects connective tissue. Sarcomatoid mesothelioma has a poor prognosis and is often resistant to treatment.

The majority of sarcomatoid mesothelioma cases are caused by exposure to asbestos, a naturally occurring mineral that was widely used in construction and manufacturing prior to the 1980s. When asbestos fibers are inhaled or ingested, they can become lodged in the mesothelial lining of the lungs, abdomen, or heart, causing damage to the cells and eventually leading to the development of mesothelioma.

Sarcomatoid Mesothelioma vs. Other Types of Mesothelioma

There are three main types of mesothelioma: epithelioid, sarcomatoid, and biphasic (a combination of both epithelioid and sarcomatoid cells). Epithelioid mesothelioma is the most common type, accounting for approximately 60-70% of all cases, while sarcomatoid mesothelioma is the least common.

Compared to epithelioid mesothelioma, which has a more favorable prognosis and is more likely to respond to treatment, sarcomatoid mesothelioma is typically more aggressive and less responsive to standard treatments such as surgery, chemotherapy, and radiation therapy. As a result, the prognosis for sarcomatoid mesothelioma is generally poor, with a median survival time of less than one year.

Causes of Sarcomatoid Mesothelioma

The primary cause of sarcomatoid mesothelioma is exposure to asbestos. Asbestos is a naturally occurring mineral that was used extensively in construction and manufacturing prior to the 1980s. When asbestos fibers are inhaled or ingested, they can become lodged in the mesothelial lining of the lungs, abdomen, or heart, causing damage to the cells and eventually leading to the development of mesothelioma.

It is important to note that not everyone who is exposed to asbestos will develop mesothelioma. However, exposure to asbestos is the primary risk factor for mesothelioma, and individuals who have been exposed to asbestos should monitor their health closely and undergo regular medical checkups.

Other Risk Factors for Sarcomatoid Mesothelioma

In addition to exposure to asbestos, there are several other risk factors for sarcomatoid mesothelioma:

  • Age: Mesothelioma is more common in individuals over the age of 65.
  • Gender: Men are more likely to develop mesothelioma than women, largely due to occupational exposure to asbestos.
  • Genetics: Some studies have suggested that certain genetic mutations may increase the risk of developing mesothelioma.
  • Smoking: While smoking is not a direct cause of mesothelioma, it can increase the risk of developing other types of cancer, which may make it more difficult to treat mesothelioma if it does develop.

Symptoms of Sarcomatoid Mesothelioma

The symptoms of sarcomatoid mesothelioma are similar to those of other types of mesothelioma and may include:

  • Chest pain
  • Shortness of breath
  • Coughing
  • Fatigue
  • Weight loss
  • Sweating
  • Fever
  • Difficulty swallowing
  • Abdominal pain or swelling (in cases of peritoneal mesothelioma)

It is important to note that these symptoms may not become apparent until several years after exposure to asbestos. In some cases, individuals may not experience symptoms until the disease has reached an advanced stage, making it more difficult to treat.

How is Sarcomatoid Mesothelioma Diagnosed?

The diagnosis of sarcomatoid mesothelioma typically involves a combination of imaging tests (such as chest X-rays or CT scans) and biopsies. During a biopsy, a small sample of tissue is removed from the affected area and examined under a microscope to determine whether cancer cells are present.

The biopsy may be performed using a variety of techniques, including:

  • Needle biopsy: A thin needle is inserted through the skin and into the affected area to remove a sample of tissue.
  • Surgical biopsy: A small incision is made in the skin and tissue is removed from the affected area.
  • Thoracoscopy or laparoscopy: A thin, flexible tube with a camera on the end is inserted into the chest or abdomen to allow the doctor to visualize the affected area and remove a tissue sample.

Staging of Sarcomatoid Mesothelioma

Staging is the process of determining the severity and extent of the cancer. In general, mesothelioma is staged using a system known as TNM, which stands for tumor, node, and metastasis. The TNM system takes into account the size and location of the tumor, whether the cancer has spread to nearby lymph nodes, and whether the cancer has metastasized (spread) to other parts of the body.

The stages of sarcomatoid mesothelioma are as follows:

  • Stage I: The cancer is localized to one area of the mesothelium and has not spread to nearby lymph nodes or other parts of the body.
  • Stage II: The cancer has spread to nearby lymph nodes but has not yet metastasized to other parts of the body.
  • Stage III: The cancer has spread to nearby organs or tissues and may have spread to nearby lymph nodes.
  • Stage IV: The cancer has spread to other parts of the body, such as the lungs, liver, or bones.

The stage of the cancer plays an important role in determining treatment options and prognosis. Generally, early-stage mesothelioma is more treatable and has a better prognosis than advanced-stage mesothelioma.

Treatment of Sarcomatoid Mesothelioma

The treatment of sarcomatoid mesothelioma depends on the stage of the cancer, the location of the tumor, and the overall health of the patient. In general, treatment options for sarcomatoid mesothelioma may include:

  • Surgery: Surgical removal of the tumor may be an option in some cases, particularly for early-stage mesothelioma.
  • Chemotherapy: Chemotherapy uses powerful drugs to kill cancer cells and may be used in combination with surgery or radiation therapy.
  • Radiation therapy: Radiation therapy uses high-energy X-rays to kill cancer cells and may be used in combination with surgery or chemotherapy.
  • Immunotherapy: Immunotherapy uses the body’s immune system to attack cancer cells and may be used in combination with other treatments.
  • Palliative care: Palliative care focuses on relieving symptoms and improving quality of life, and may be recommended in cases where curative treatment is not possible.

It is important to note that sarcomatoid mesothelioma is often resistant to treatment, and the prognosis for this type of cancer is generally poor. However, new treatments and therapies are being developed and tested, and individuals diagnosed with sarcomatoid mesothelioma may be eligible to participate in clinical trials of these new treatments.

Prognosis of Sarcomatoid Mesothelioma

The prognosis for sarcomatoid mesothelioma is generally poor, with a median survival time of less than one year. However, the prognosis may vary depending on the stage of the cancer, the location of the tumor, the age and overall health of the patient, and other factors.

For individuals with early-stage sarcomatoid mesothelioma, the prognosis may be more favorable, particularly if the tumor can be surgically removed. However, for individuals with advanced-stage sarcomatoid mesothelioma, the prognosis is generally poor, and the focus of treatment may shift to palliative care to relieve symptoms and improve quality of life.

Living with Sarcomatoid Mesothelioma

Living with sarcomatoid mesothelioma can be challenging, both for patients and for their loved ones. It is important to have a strong support system in place and to work closely with a healthcare team that is experienced in treating mesothelioma.

There are also several lifestyle changes that individuals with sarcomatoid mesothelioma can make to help manage their symptoms and improve their quality of life, including:

  • Eating a healthy diet
  • Engaging in regular exercise (if possible)
  • Getting enough rest and managing stress
  • Participating in activities that bring joy and fulfillment
  • Connecting with others in the mesothelioma community through support groups or online forums

Prevention of Sarcomatoid Mesothelioma

The primary way to prevent sarcomatoid mesothelioma is to avoid exposure to asbestos. If you work in an industry that may expose you to asbestos, it is important to take the proper precautions to minimize your risk of exposure, such as wearing protective equipment and following workplace safety guidelines.

If you suspect that you may have been exposed to asbestos in the past, it is important to undergo regular medical checkups and to notify your healthcare provider of your potential exposure to asbestos.
