What is Malignant Mesothelioma Sarcomatoid Type?
Malignant mesothelioma sarcomatoid type, also known as sarcomatoid mesothelioma, is a rare and aggressive form of cancer that affects the mesothelial cells, which line the lungs, abdomen, or heart. It is called “sarcomatoid” because the cancer cells resemble those found in sarcoma, a type of cancer that affects the connective tissues of the body, such as muscles, bones, and cartilage. Sarcomatoid mesothelioma accounts for only 10 to 20 percent of all mesothelioma cases and is the least common subtype. It is also the most aggressive form of mesothelioma and has a poor prognosis compared to the other subtypes.
Sarcomatoid mesothelioma is classified as a biphasic or mixed subtype when it contains both epithelioid and sarcomatoid cells. This subtype has a better prognosis than pure sarcomatoid mesothelioma because the epithelioid cells can respond better to treatment. The sarcomatoid cells have a spindle-shaped appearance and can be more difficult to diagnose and treat because they are highly resistant to chemotherapy and radiation therapy.
There are several types of sarcomatoid mesothelioma based on their location and the type of cell they originate from. These include pleural sarcomatoid mesothelioma, which affects the lining of the lungs, peritoneal sarcomatoid mesothelioma, which affects the lining of the abdomen, and pericardial sarcomatoid mesothelioma, which affects the lining of the heart. Each type of sarcomatoid mesothelioma has its own specific symptoms and treatment options.
Causes and Risk Factors
As with all subtypes of mesothelioma, the primary cause of malignant mesothelioma sarcomatoid type is exposure to asbestos. Asbestos is a naturally occurring mineral that was widely used in construction, shipbuilding, and manufacturing industries due to its heat-resistant properties. When asbestos fibers are inhaled or ingested, they can become trapped in the lining of the lungs, abdomen, or heart, causing inflammation and scarring over time. This can ultimately lead to the development of mesothelioma, including the sarcomatoid subtype.
The risk of developing malignant mesothelioma sarcomatoid type is higher for those who have had prolonged exposure to asbestos, such as industrial workers, miners, military personnel, and those who live in buildings with asbestos-containing materials. Smoking does not increase the risk of developing mesothelioma, but it can increase the risk of developing lung cancer in those who have been exposed to asbestos.
Symptoms and Diagnosis
Symptoms of malignant mesothelioma sarcomatoid type can vary depending on the location of the cancer, but they typically include shortness of breath, chest or abdominal pain, coughing, fever, weight loss, and fatigue. Because these symptoms are common to many other conditions, diagnosing sarcomatoid mesothelioma can be challenging, especially in the early stages.
Diagnosis of malignant mesothelioma sarcomatoid type typically involves a combination of imaging tests, such as X-rays, CT scans, or MRIs, and tissue biopsies. A biopsy is a procedure that involves removing a small sample of tissue from the affected area and examining it under a microscope to check for cancer cells. Because sarcomatoid mesothelioma can be difficult to distinguish from other types of cancer or non-cancerous conditions, such as sarcomas or fibrous tumors, a pathologist with expertise in mesothelioma diagnosis is usually needed to confirm the diagnosis.
Treatment Options
The treatment options for malignant mesothelioma sarcomatoid type depend on several factors, including the location and stage of the cancer, the age and overall health of the patient, and the preferences of the patient and their healthcare team. Because sarcomatoid mesothelioma is a rare and aggressive form of cancer, treatment can be more difficult and may involve a combination of surgery, chemotherapy, and radiation therapy.
Surgery is often the first-line treatment for sarcomatoid mesothelioma when it is localized and has not spread to other areas of the body. The goal of surgery is to remove as much of the cancerous tissue as possible to improve the patient’s quality of life and prolong survival. However, surgery is not always an option for sarcomatoid mesothelioma due to its location or the extent of the cancer.
Chemotherapy is a systemic treatment that involves using drugs to kill cancer cells throughout the body. It can be used before or after surgery to shrink the tumor and prevent the cancer from spreading, or as a palliative treatment to relieve symptoms and improve quality of life. Sarcomatoid mesothelioma is resistant to many chemotherapy drugs, so treatment may involve using a combination of drugs or newer, experimental drugs.
Radiation therapy uses high-energy radiation to kill cancer cells and shrink tumors. It may be used alone or in combination with surgery or chemotherapy to treat sarcomatoid mesothelioma. However, radiation therapy can also damage healthy tissues and cause side effects, such as fatigue, skin irritation, and nausea.
Prognosis and Survival Rates
The prognosis for malignant mesothelioma sarcomatoid type is generally poor, with a median survival rate of 6 to 12 months from the time of diagnosis. This is due in part to the aggressive nature of the cancer and its tendency to metastasize to other areas of the body. However, the prognosis can vary depending on the stage of the cancer at the time of diagnosis, the location of the cancer, and the patient’s age and overall health.
Survival rates for sarcomatoid mesothelioma are lower than for the other subtypes of mesothelioma, with a five-year survival rate of only 5 to 10 percent. However, some patients may be eligible for clinical trials or newer treatment options that can improve their chances of survival and enhance their quality of life.
Prevention and Awareness
The best way to prevent mesothelioma, including malignant mesothelioma sarcomatoid type, is to avoid exposure to asbestos. If you work in an industry that may involve exposure to asbestos, be sure to follow safety guidelines and use protective equipment, such as respirators or protective clothing. If you live in a building with asbestos-containing materials, have them removed or encapsulated by a licensed professional. It is also important to raise awareness about the risks of asbestos exposure and advocate for better regulations to protect workers and the general public from this dangerous mineral.
