Mesothelioma: Statistics, Symptoms,Causes and Treatment

What is Mesothelioma?

Mesothelioma is a rare and aggressive form of cancer that affects the mesothelium, which is the thin tissue lining that covers the organs in the body’s cavities. It is primarily caused by exposure to asbestos, a naturally occurring mineral that was widely used in various industries due to its heat-resistant and insulating properties. In this article, we will delve into the causes, symptoms, diagnosis, treatment and legal options for mesothelioma.

What is Survival Rates Of Mesothelioma?

According to the American Cancer Society, the overall 5-year survival rate for mesothelioma is about 10%. This means that, on average, only 10% of people diagnosed with mesothelioma will survive for 5 years or more after diagnosis.

For localized mesothelioma (where the tumor is confined to the lining of one organ and has not spread to nearby lymph nodes or distant sites), the 5-year survival rate is higher, ranging from 20% to 50% or more, depending on the specific location and type of mesothelioma.

For advanced or metastatic mesothelioma (where the cancer has spread to distant organs or lymph nodes), the prognosis is generally poorer, with lower survival rates. The 5-year survival rate for advanced mesothelioma is typically less than 10%.

Factors that can impact mesothelioma survival rates include:

1. Stage of the disease: Early detection and diagnosis of mesothelioma can significantly impact survival rates. Localized mesothelioma that is diagnosed in its early stages may be more treatable and have a better prognosis compared to advanced or metastatic mesothelioma.
2. Type and location of the tumor: The type and location of the mesothelioma tumor can also affect survival rates. Pleural mesothelioma, which affects the lining of the lungs, is the most common type and generally has a poorer prognosis compared to peritoneal mesothelioma, which affects the lining of the abdomen.
3. Age and overall health of the patient: The age and overall health of the patient can also impact survival rates. Younger and healthier patients may have a better prognosis compared to older patients or those with pre-existing health conditions.
4. Treatment received: The type of treatment received can also affect survival rates. Mesothelioma treatment typically involves a combination of surgery, radiation therapy, chemotherapy, targeted therapy, immunotherapy, and/or palliative care. The extent and effectiveness of the treatment received can impact survival rates.
5. Response to treatment: The response to treatment can also impact survival rates. Some patients may respond well to treatment and experience better outcomes, while others may not respond as well and have a poorer prognosis.

What is Causes of Mesothelioma?

As mentioned earlier, the primary cause of mesothelioma is exposure to asbestos. Asbestos is a fibrous mineral that was used in a wide range of industries, such as construction, manufacturing, shipbuilding, automotive and textiles, due to its durability and fire-resistant properties. When asbestos fibers are disturbed or released into the air, they can be inhaled or swallowed and over time, they can accumulate in the mesothelium, causing inflammation, scarring and eventually leading to the development of mesothelioma.

Apart from asbestos exposure, there are other risk factors that have been associated with mesothelioma, although they are relatively rare. These include exposure to other minerals with asbestos-like properties, such as erionite and talc, as well as certain genetic mutations that may increase the susceptibility to mesothelioma.

What is Statistics About Mesothelioma?

Here are some statistics about mesothelioma:

1. Incidence: The incidence of mesothelioma is relatively low compared to other types of cancer. According to the American Cancer Society, in the United States, there are estimated to be around 3,000 new cases of mesothelioma diagnosed each year.
2. Age and gender: Mesothelioma is more common in older people, with the majority of cases diagnosed in people who are over 65 years old. Men are more commonly affected than women, likely due to higher rates of occupational asbestos exposure among males in the past.
3. Occupational exposure: Occupational exposure to asbestos is the primary risk factor for mesothelioma. People who have worked in industries such as construction, shipbuilding, asbestos mining and manufacturing and automotive repair have a higher risk of developing mesothelioma due to prolonged exposure to asbestos fibers.
4. Environmental exposure: While occupational exposure is the most significant risk factor, mesothelioma can also occur due to environmental exposure to asbestos. This can happen through living near asbestos mines, asbestos-containing materials in buildings or asbestos-contaminated soil.
5. Latency period: Mesothelioma has a long latency period, which means that it can take many years, even decades, for symptoms to manifest after exposure to asbestos. The latency period can range from 10 to 50 years or even longer.
6. Prognosis: Mesothelioma has a poor prognosis, with a relatively low overall survival rate. The prognosis depends on various factors such as the stage of the disease at diagnosis, the location of the tumor, the type of mesothelioma and the overall health of the patient. The median survival time for mesothelioma is typically around 8 to 12 months but this can vary widely depending on people circumstances.
7. Treatment options: Treatment for mesothelioma typically involves a combination of surgery, radiation therapy and chemotherapy. But, due to the aggressive nature of the disease, mesothelioma can be challenging to treat and curative treatment options are limited. Palliative care, which focuses on managing symptoms and improving quality of life, may also very helpful part of the treatment plan.
8. Legal and compensation issues: Due to the link between mesothelioma and asbestos exposure, there have been numerous legal cases and compensation claims related to mesothelioma. Many countries have regulations in place to protect workers and the general population from asbestos exposure and people who have been diagnosed with mesothelioma may be entitled to compensation for their medical expenses, lost wages and other damages related to their illness.
9. Prevention: Asbestos has been widely regulated and restricted in many countries due to its health risks, including mesothelioma. Preventive measures include proper asbestos management in workplaces, adherence to regulations regarding asbestos handling and removal and public awareness about the dangers of asbestos exposure. If you are in an occupation with potential asbestos exposure, it is helpful to follow proper safety guidelines and use personal protective equipment.

What is Symptoms of Mesothelioma?

The symptoms of mesothelioma can change according to the type and stage of the cancer but here are some common symptoms:

1. Difficulty breathing or shortness of breath
2. Chest pain or discomfort
3. Persistent cough or hoarseness
4. Fatigue and weakness
5. Unexplained weight loss
6. Swelling or lumps in the abdomen
7. Bowel or digestive changes
8. Night sweats
9. Fever
10. Muscle weakness

Diagnosis of Mesothelioma:

Diagnosing mesothelioma can be complex and may require a combination of medical history, physical examination, imaging tests and biopsies. A detailed medical history, including any history of asbestos exposure, along with a physical examination, may provide important clues to the possibility of mesothelioma. However, further testing is typically needed to confirm the diagnosis.

Imaging tests, such as X-rays, CT scans, and MRI scans, can help visualize the affected areas and detect any abnormalities in the mesothelium or other tissues. However, imaging alone is not sufficient to confirm mesothelioma, and a biopsy is usually required.

A biopsy involves removing a small sample of tissue from the suspected area and examining it under a microscope to determine if there are cancerous cells present. There are different types of biopsies, including needle biopsies, thoracoscopy (for pleural mesothelioma), laparoscopy (for peritoneal mesothelioma), and mediastinoscopy (for pericardial mesothelioma). The biopsy results can provide definitive confirmation of mesothelioma and also help determine the type and stage of the cancer, which are crucial factors in determining the appropriate treatment plan.

Once the diagnosis of mesothelioma is confirmed, further tests may be conducted to determine the stage of the cancer. Staging helps determine the extent and spread of the cancer and plays a significant role in guiding the treatment options. Mesothelioma is typically staged using the TNM system, which stands for tumor, node, and metastasis. It takes into account the size and location of the tumor, involvement of nearby lymph nodes, and presence of metastasis (spread to other distant organs).

What is Treatment Ways of Mesothelioma?

The treatment of mesothelioma change according to various factors, including the type, stage and location of the cancer, as well as the overall health and preferences of the patient. Here are treatment options for mesothelioma:

1. Surgery: Surgery may be done to remove the tumor and surrounding affected tissues. The type of surgery may vary depending on the location of the cancer. For pleural mesothelioma, options may include pleurectomy/decortication (P/D) which involves removing the pleura and any visible tumor, or extrapleural pneumonectomy (EPP) which involves removing the entire lung along with the pleura and other affected tissues. For peritoneal mesothelioma, options may include cytoreductive surgery with heated intraperitoneal chemotherapy (HIPEC) which involves removing the tumor and lining of the abdomen followed by heated chemotherapy to kill remaining cancer cells. Surgery for pericardial mesothelioma is rare due to the delicate nature of the heart.
2. Radiation therapy: Radiation therapy uses high-energy rays to kill cancer cells. It may be used before surgery (neoadjuvant radiation), during surgery (intraoperative radiation), or after surgery (adjuvant radiation) to help kill remaining cancer cells or relieve symptoms.
3. Chemotherapy: Chemotherapy uses drugs to kill cancer cells throughout the body. It may be used before surgery (neoadjuvant chemotherapy), after surgery (adjuvant chemotherapy), or as the main treatment for advanced mesothelioma. Chemotherapy can also be used in combination with surgery and radiation therapy.
4. Targeted therapy: Targeted therapy uses drugs that specifically target cancer cells, blocking their growth or causing them to die. This type of therapy is still being researched and may be used in certain cases as part of a personalized treatment plan.
5. Immunotherapy: Immunotherapy uses drugs to stimulate the immune system to recognize and attack cancer cells. It is a rapidly evolving field, and clinical trials are ongoing to explore the use of immunotherapy in mesothelioma treatment.
6. Palliative care: Palliative care focuses on providing relief from symptoms, managing pain, and improving quality of life for patients with mesothelioma. Palliative care can be provided alongside curative treatment or as the main focus of care for patients who are not eligible for aggressive treatment.

Legal Options for Mesothelioma:

As mesothelioma is primarily caused by asbestos exposure, people who have been diagnosed with mesothelioma may have legal options to seek compensation for their condition. Here are your guide::

1. Asbestos trust funds: Many companies that used asbestos in their products have established trust funds to compensate victims of asbestos-related diseases, including mesothelioma. These trust funds were set up as a result of lawsuits and bankruptcies of asbestos companies, and they provide compensation to eligible people who have been diagnosed with mesothelioma due to asbestos exposure.
2. Personal injury lawsuits: People who have been diagnosed with mesothelioma may be eligible to file personal injury lawsuits against the parties responsible for their asbestos exposure. This may include manufacturers of asbestos-containing products, employers who failed to provide adequate safety measures, or other parties who may have been negligent in protecting people from asbestos exposure.
3. Wrongful death lawsuits: If a loved one has passed away due to mesothelioma, surviving family members may have the option to file wrongful death lawsuits to seek compensation for their loss. This may include compensation for medical expenses, lost wages, pain and suffering, and loss of companionship.

What is Peritoneal Mesothelioma?

Peritoneal mesothelioma is a type of mesothelioma that affects the lining of the abdominal cavity, known as the peritoneum. It is a rare and aggressive cancer that originates from the cells that make up the peritoneal lining. Peritoneal mesothelioma accounts for approximately 10-20% of all mesothelioma cases, with the more common form being pleural mesothelioma which affects the lining of the lungs.

Peritoneal mesothelioma is primarily caused by asbestos exposure. Asbestos fibers, when inhaled or ingested, can become lodged in the peritoneal lining, leading to inflammation, damage to the cells and eventually the development of cancer. Other risk factors for peritoneal mesothelioma may include exposure to erionite, a naturally occurring mineral fiber similar to asbestos, and certain genetic mutations.

Symptoms of peritoneal mesothelioma can be non-specific and may include abdominal pain, swelling or fluid buildup in the abdomen (ascites), unexplained weight loss, changes in bowel or urinary habits, nausea and vomiting. These symptoms may be similar to other conditions and diagnosis often requires imaging tests such as CT scans or MRI, as well as biopsy for confirmation.

Treatment for peritoneal mesothelioma typically involves a multimodal approach that may include surgery, chemotherapy and radiation therapy, as well as palliative care to manage symptoms and improve quality of life. Cytoreductive surgery with heated intraperitoneal chemotherapy (HIPEC) is a common surgical approach for peritoneal mesothelioma, which involves removing visible tumors in the abdomen followed by the administration of heated chemotherapy directly into the abdominal cavity to target any remaining cancer cells. Other treatment options may include systemic chemotherapy, targeted therapy and immunotherapy, depending on the stage and extent of the disease, as well as the patient’s overall health.

Prognosis for peritoneal mesothelioma varies depending on several factors, including the stage of the disease at diagnosis, the overall health of the patient, and the effectiveness of the chosen treatment approach. But, compared to pleural mesothelioma, peritoneal mesothelioma has been associated with a slightly better prognosis, with some studies showing improved survival rates, particularly with the use of cytoreductive surgery with HIPEC. Nevertheless, peritoneal mesothelioma remains a challenging cancer to treat, and early detection and intervention are crucial for better outcomes.

In addition to medical management, people diagnosed with peritoneal mesothelioma may also face legal and compensation issues, as asbestos exposure is the primary cause of this cancer. Many countries have regulations in place to protect workers and the general population from asbestos exposure and people who have been diagnosed with peritoneal mesothelioma may be entitled to compensation for their medical expenses, lost wages and other damages related to their illness.
