Hello and welcome to this journal article on lung mesothelioma. Mesothelioma is a rare and aggressive type of cancer that affects the tissue lining of various organs, including the lungs. In this article, we will explore the causes, symptoms, diagnosis, treatment, and prognosis of lung mesothelioma. We will also provide some helpful tips on how to prevent this disease. Let’s dive in.
What is Lung Mesothelioma?
Lung mesothelioma is a cancer of the lining of the lung, known as the pleura. This type of mesothelioma is almost always caused by exposure to asbestos fibers. Asbestos is a naturally occurring mineral that was widely used in various industries for its heat-resistant properties. When asbestos fibers are inhaled or ingested, they can become trapped in the lungs and cause irritation, inflammation, and scarring. Over time, these changes can lead to the development of cancerous cells.
There are mainly two types of lung mesothelioma:
| Type | Description |
|---|---|
| Pleural Mesothelioma | It is the most common type of mesothelioma. It develops in the lining of the lungs, known as the pleura. The pleura is a thin membrane that covers the lungs and lines the chest cavity. Pleural mesothelioma can cause chest pain, coughing, shortness of breath, and other respiratory symptoms. |
| Peritoneal Mesothelioma | It is a rare type of mesothelioma that develops in the lining of the abdomen, known as the peritoneum. Peritoneal mesothelioma can cause abdominal pain, swelling, and other digestive symptoms. |
Causes of Lung Mesothelioma
The primary cause of lung mesothelioma is exposure to asbestos fibers. Asbestos was widely used in various industries, such as construction, shipbuilding, automotive, and manufacturing, until the 1980s. Workers who were exposed to asbestos fibers, especially for prolonged periods, are at a higher risk of developing lung mesothelioma. However, it is also possible for family members of asbestos workers or individuals who have had secondary exposure to asbestos fibers to develop this disease.
Other possible causes of lung mesothelioma include:
- Zeolites: A naturally occurring mineral that is similar in structure to asbestos.
- Radiation: Exposure to high levels of radiation can increase the risk of lung cancer, including mesothelioma.
- Genetics: Certain genetic mutations may increase the risk of developing mesothelioma.
Symptoms of Lung Mesothelioma
The symptoms of lung mesothelioma may not appear for several years after asbestos exposure. In some cases, it can take up to 50 years for symptoms to manifest. The symptoms of lung mesothelioma can be similar to those of other lung diseases, which can make it challenging to diagnose. Some common symptoms of lung mesothelioma include:
- Chest pain
- Coughing
- Shortness of breath
- Fatigue
- Unexplained weight loss
- Difficulty swallowing
- Fever or night sweats
- Cyanosis (blue tinting of the skin due to lack of oxygen)
Early Symptoms of Lung Mesothelioma
The early symptoms of lung mesothelioma may be mild and vague, making it challenging to diagnose the disease. Some early symptoms of lung mesothelioma include:
- Mild chest pain
- Frequent coughing
- Mild shortness of breath
- Fatigue or weakness
- Loss of appetite
- Muscle weakness
- Night sweats
- Fever
Advanced Symptoms of Lung Mesothelioma
The advanced symptoms of lung mesothelioma are much more severe and can significantly impact an individual’s quality of life. Some advanced symptoms of lung mesothelioma include:
- Severe chest pain
- Severe coughing
- Severe shortness of breath
- Unexplained weight loss
- Difficulty swallowing
- Fever or night sweats
- Cyanosis (blue tinting of the skin due to lack of oxygen)
- Bowel obstruction
Diagnosing Lung Mesothelioma
Diagnosing lung mesothelioma can be challenging, as the symptoms are similar to those of other lung diseases. Additionally, the disease can take several years to manifest after asbestos exposure, making it difficult to identify the source of the illness. Some of the diagnostic tests used to diagnose lung mesothelioma include:
- Chest X-ray
- CT scan
- MRI scan
- Biopsy
- PET scan
Biopsy for Diagnosing Lung Mesothelioma
A biopsy is a procedure that involves removing a tissue sample from the affected area and examining it under a microscope. This test is typically performed when other diagnostic tests are inconclusive, and lung mesothelioma is suspected. There are several types of biopsies, including:
- Needle biopsy
- Endoscopic biopsy
- Thoracoscopy
Treating Lung Mesothelioma
Treating lung mesothelioma can be challenging, as the disease is often diagnosed in later stages when it has already spread to other parts of the body. The treatment for lung mesothelioma depends on several factors, including the type of mesothelioma, the stage of the disease, and the patient’s overall health. Some of the treatment options for lung mesothelioma include:
- Surgery
- Chemotherapy
- Radiation therapy
- Immunotherapy
- Palliative care
Surgical Treatment for Lung Mesothelioma
Surgery is one of the primary treatments for lung mesothelioma, especially for early-stage cancer. The type of surgery depends on the extent and location of the cancer. Some of the surgical options for lung mesothelioma include:
- Pleurectomy/decortication (P/D)
- Extrapleural pneumonectomy (EPP)
- Extended pleurectomy/decortication (EP/D)
Chemotherapy for Lung Mesothelioma
Chemotherapy is a type of cancer treatment that uses drugs to kill cancerous cells. Chemotherapy may be used alone or in combination with other treatments, such as surgery or radiation therapy. Some of the chemotherapy drugs used to treat lung mesothelioma include:
- Pemetrexed
- Cisplatin
- Gemcitabine
- Carboplatin
- Methotrexate
Radiation Therapy for Lung Mesothelioma
Radiation therapy is a type of cancer treatment that uses high-energy rays to destroy cancerous cells. Radiation therapy may be used alone or in combination with other treatments, such as surgery or chemotherapy. Some of the radiation therapy options for lung mesothelioma include:
- External beam radiation therapy (EBRT)
- Intensity-modulated radiation therapy (IMRT)
- Brachytherapy
Immunotherapy for Lung Mesothelioma
Immunotherapy is a type of cancer treatment that uses the body’s immune system to fight cancerous cells. Immunotherapy may be used alone or in combination with other treatments, such as surgery or chemotherapy. Some of the immunotherapy drugs used to treat lung mesothelioma include:
- Keytruda (Pembrolizumab)
- Opdivo (Nivolumab)
- Yervoy (Ipilimumab)
- Atezolizumab
- Tremelimumab
Palliative Care for Lung Mesothelioma
Palliative care is a type of care that focuses on relieving symptoms and improving the quality of life for patients with serious illnesses, such as lung mesothelioma. Palliative care may be used in conjunction with other treatments or as a standalone therapy. Some of the palliative care options for lung mesothelioma include:
- Pain management
- Emotional support
- Nutritional support
- Hospice care
- End-of-life planning
Prognosis of Lung Mesothelioma
The prognosis of lung mesothelioma depends on several factors, including the stage of the disease, the location of the tumor, the patient’s overall health, and their response to treatment. Unfortunately, the prognosis for lung mesothelioma is generally poor, as the disease is often diagnosed in later stages when it has already spread to other parts of the body. According to the American Cancer Society, the five-year survival rate for mesothelioma is around 10%. However, with early detection and aggressive treatment, some patients may have a better chance of survival.
