What is Sarcomatoid Mesothelioma?

🩸 Introduction

Greetings, readers!

Many people have heard of mesothelioma, a rare and aggressive cancer that affects the lining of organs, most commonly the lungs. However, not everyone is aware of the different types of mesothelioma, including sarcomatoid mesothelioma. This specific type is the rarest, most aggressive, and most difficult to treat. Unfortunately, it is also the most common type diagnosed in the United States, accounting for roughly 10-20% of all mesothelioma cases.

In this article, we will define what sarcomatoid mesothelioma is, delve into its causes, symptoms, diagnosis, and treatment options, as well as answer some frequently asked questions about this rare cancer.

🧬 What is Sarcomatoid Mesothelioma?

Sarcomatoid mesothelioma is a type of mesothelioma cancer that affects the mesothelial cells, the thin layer of tissue that covers and protects the organs in the body. In sarcomatoid mesothelioma, these cells mutate into unusual sarcoma-like cells. Sarcoma is a type of cancer that originates from connective tissue or supportive tissue such as bone, cartilage, or fat. The mutated cells form tumors that can invade and harm nearby organs and tissues, making it very challenging to treat.

Other Types of Mesothelioma

There are two other types of mesothelioma aside from sarcomatoid: epithelioid and biphasic.

Epithelioid mesothelioma is the most common type, accounting for around 50-70% of cases. It is typically easier to treat than sarcomatoid mesothelioma because the cells are more normal and uniform, making them easier to identify and target with treatment.

Biphasic mesothelioma is a mix of both sarcomatoid and epithelioid cells, making it more difficult to treat than epithelioid mesothelioma but less aggressive than sarcomatoid mesothelioma.

How Common is Sarcomatoid Mesothelioma?

Sarcomatoid mesothelioma is rare, accounting for approximately 10-20% of all mesothelioma cases diagnosed in the United States. It is more common in men than in women and is typically diagnosed in individuals over the age of 50.

🧪 What Causes Sarcomatoid Mesothelioma?

The primary cause of sarcomatoid mesothelioma is exposure to asbestos. Asbestos is a group of naturally occurring minerals that was used widely in the United States in the 20th century in the construction, automotive, and manufacturing industries. When inhaled, asbestos fibers can become lodged in the mesothelial cells, leading to mutations and the development of sarcomatoid mesothelioma.

It is important to note that exposure to asbestos does not guarantee the development of sarcomatoid mesothelioma. There have been cases where individuals with high levels of asbestos exposure do not develop mesothelioma, and others with minimal exposure develop the disease.

Other Risk Factors

In addition to asbestos exposure, there are other risk factors that may increase the likelihood of developing sarcomatoid mesothelioma. These include:

  • Exposure to other harmful chemicals, such as erionite
  • Exposure to radiation therapy
  • A weakened immune system
  • Genetic predisposition
  • Having a history with a mesothelioma diagnosis in the family

🩹 Symptoms of Sarcomatoid Mesothelioma

The symptoms of sarcomatoid mesothelioma can be similar to other types of mesothelioma and can take several years to manifest. Some symptoms may include:

  • Chest pain
  • Shortness of breath
  • Difficulty breathing or swallowing
  • Cough
  • Fatigue
  • Night Sweats
  • Unintentional weight loss

Unfortunately, these symptoms are not specific to sarcomatoid mesothelioma and may be associated with other illnesses. This is partly why sarcomatoid mesothelioma is difficult to diagnose, and often, by the time it is diagnosed, it has already spread to other parts of the body.

Diagnosing Sarcomatoid Mesothelioma

The diagnostic process for sarcomatoid mesothelioma typically includes:

  1. Medical History and Physical Exam: The doctor will ask about the patient’s medical history and perform a physical exam to identify any signs of sarcomatoid mesothelioma, such as swelling or fluid buildup.
  2. Imaging Tests: The doctor may perform imaging tests, such as X-rays, CT scans, or MRIs, to get a better look at the organs and tissues in the body and identify any tumors.
  3. Biopsy: If tumors or abnormal tissue are found, the doctor may perform a biopsy, which involves removing a small sample of tissue for examination under a microscope. This can help determine if the tissue is cancerous and what type of cancer it is.

🏥 Treatment Options for Sarcomatoid Mesothelioma

Sarcomatoid mesothelioma is challenging to treat and may require a combination of different therapies depending on the stage of the cancer and the overall health of the patient. Some treatment options may include:

  • Surgery: In some cases, surgery may be an option to remove tumors and affected tissue. This is typically only an option if the cancer is caught early and has not spread to other parts of the body.
  • Chemotherapy: Chemotherapy involves using drugs to destroy cancer cells. This can be given orally or intravenously, and it can be administered alone or in combination with surgery or radiation therapy.
  • Radiation Therapy: Radiation therapy uses high-energy beams to destroy cancer cells. This is typically used in combination with surgery or chemotherapy to target specific areas where the cancer has spread.

It is essential to note that not all patients will be eligible for all types of treatment. Sarcomatoid mesothelioma is often diagnosed at a later stage, making it difficult to treat, and some patients may not be healthy enough to undergo aggressive forms of therapy.

📝 Frequently Asked Questions (FAQs)

1. What is the survival rate for sarcomatoid mesothelioma?

The survival rate for sarcomatoid mesothelioma is typically low, with an average life expectancy of 6-12 months after diagnosis.
