The little-known type of mesothelioma that can be difficult to diagnose and treat
Greetings, esteemed readers! Mesothelioma is a rare cancer that develops in the lining of the lungs, chest, or abdomen. It is typically caused by asbestos exposure, and unfortunately, it has a poor prognosis. Most people have heard of pleural mesothelioma or peritoneal mesothelioma, but there is a lesser-known type called transitional mesothelioma. In this article, we will dive deep into transitional mesothelioma, explaining what it is, its symptoms, diagnosis, treatment options, and more. So, let’s get started!
What is Transitional Mesothelioma?
👉 Transitional mesothelioma, also called biphasic mesothelioma, is a rare form of mesothelioma that accounts for about 20-40% of all mesothelioma cases.
Transitional mesothelioma is a combination of epithelioid mesothelioma and sarcomatoid mesothelioma. It has both the characteristics of these two subtypes of mesothelioma, which makes it difficult to diagnose and treat. Depending on the proportion of each subtype, the tumor can have various features and behaviors.
What Causes Transitional Mesothelioma?
Like other types of mesothelioma, the primary cause of transitional mesothelioma is asbestos exposure. Asbestos is a naturally occurring mineral that was widely used in construction, shipbuilding, automotive, and other industries until the 1980s. When asbestos fibers are inhaled or ingested, they can get trapped in the mesothelial cells that line the organs and cause chronic inflammation, DNA damage, and abnormal cell growth. Over time, these cells can become cancerous and spread to nearby tissues and organs.
What are the Symptoms of Transitional Mesothelioma?
The symptoms of transitional mesothelioma are similar to those of other mesothelioma types and can include:
| Common Symptoms | Less Common Symptoms |
|---|---|
| Chest pain | Weight loss |
| Shortness of breath | Night sweats |
| Cough | Chest wall mass |
| Difficulty swallowing | Fever |
However, the specific symptoms can vary depending on the location and stage of the cancer. For example, if the tumor affects the lungs, the patient may experience pleural effusion (fluid buildup in the lungs) and respiratory problems. If the tumor affects the abdomen, the patient may have abdominal pain and swelling, nausea, and bowel changes.
How Is Transitional Mesothelioma Diagnosed?
Diagnosing transitional mesothelioma is challenging because it has mixed histology (cellular structure) and can mimic other types of cancer or benign conditions. The diagnostic process usually involves:
1. Medical history and physical examination:
The doctor will ask about the patient’s exposure to asbestos and any symptoms they are experiencing. They will also check for any abnormal lumps, swelling, or fluid buildup.
2. Imaging tests:
The doctor may order X-rays, CT scans, MRI, or PET scans to look for signs of tumors and evaluate the extent of the cancer.
3. Biopsy:
The doctor will take a tissue sample from the affected area and examine it under a microscope to confirm the diagnosis and determine the subtype of mesothelioma.
What Are the Treatment Options for Transitional Mesothelioma?
👉 The treatment options for transitional mesothelioma depend on the stage, location, and subtype of the cancer, as well as the patient’s overall health and preferences.
1. Surgery:
Surgery may be an option to remove the tumor and surrounding tissues if the cancer is localized and the patient is healthy enough to undergo the procedure. The type of surgery will depend on the extent and location of the tumor and may include:
- Pleurectomy/decortication (P/D): removing the pleura and the affected lung tissue
- Extrapleural pneumonectomy (EPP): removing the entire lung, pleura, and diaphragm
- Peritonectomy: removing the lining of the abdomen and the affected organs
2. Chemotherapy:
Chemotherapy involves using drugs to kill cancer cells or slow their growth. Chemotherapy may be given before or after surgery or as a stand-alone treatment. Common chemotherapy drugs for mesothelioma include cisplatin, carboplatin, pemetrexed, and gemcitabine.
3. Radiation Therapy:
Radiation therapy uses high-energy beams to destroy cancer cells or shrink tumors. Radiation therapy may be used alone or in combination with surgery and/or chemotherapy.
4. Clinical Trials:
Clinical trials are ongoing research studies that test new treatments or combinations of treatments for mesothelioma. Participation in clinical trials may be an option for patients who do not respond to standard treatments or have limited treatment options.
What Is the Prognosis for Transitional Mesothelioma?
The prognosis for transitional mesothelioma is generally not as good as that for epithelioid mesothelioma but better than sarcomatoid mesothelioma. The prognosis depends on various factors, such as the stage and location of the cancer, the histology, the patient’s age and overall health, and the treatment response. The median survival time for transitional mesothelioma is around 15-18 months.
FAQs About Transitional Mesothelioma
1. Is transitional mesothelioma curable?
No, there is currently no cure for mesothelioma, including transitional mesothelioma. However, treatments can help control the cancer and improve the patient’s quality of life.
2. How common is transitional mesothelioma?
Transitional mesothelioma accounts for about 20-40% of all mesothelioma cases.
3. How is transitional mesothelioma different from other types of mesothelioma?
Transitional mesothelioma is a combination of epithelioid mesothelioma and sarcomatoid mesothelioma. It has both the characteristics of these two subtypes of mesothelioma, which makes it difficult to diagnose and treat.
4. What are the risk factors for transitional mesothelioma?
The primary risk factor for transitional mesothelioma is asbestos exposure. Other factors that may increase the risk include smoking, genetic predisposition, and radiation exposure.
5. Can transitional mesothelioma spread to other parts of the body?
Yes, transitional mesothelioma can metastasize (spread) to other organs and tissues, such as the lymph nodes, liver, bones, and brain.
6. What are the long-term effects of transitional mesothelioma?
The long-term effects of transitional mesothelioma can vary depending on the patient’s individual case. However, most patients experience some degree of physical and emotional challenges, such as pain, fatigue, anxiety, depression, and financial strain.
7. How can I reduce my risk of developing transitional mesothelioma?
The best way to reduce your risk of developing transitional mesothelioma is to avoid asbestos exposure. If you work in an industry that uses or used asbestos, make sure to follow safety regulations and wear protective equipment. If you suspect that your home or workplace may have asbestos-containing materials, hire a professional asbestos abatement company to remove them.
8. Can I file a lawsuit if I have transitional mesothelioma?
Yes, you may be eligible to file a lawsuit against the companies that exposed you to asbestos and caused your mesothelioma. A qualified mesothelioma lawyer can help you understand your legal rights and options.
9. Can alternative therapies cure transitional mesothelioma?
There is no scientific evidence to support the effectiveness of alternative therapies, such as herbal remedies, acupuncture, or dietary supplements, in curing mesothelioma or prolonging survival. However, some patients may use complementary therapies, such as meditation or yoga, to manage symptoms and improve their quality of life.
10. What should I do if I have been diagnosed with transitional mesothelioma?
If you have been diagnosed with transitional mesothelioma, it is crucial to seek medical advice from a mesothelioma specialist and discuss your treatment options. You may also want to consider joining a support group or seeking legal assistance if you believe that your asbestos exposure was due to someone else’s negligence.
11. Can transitional mesothelioma affect children?
While mesothelioma is rare in children, it can occur if they have been exposed to asbestos, either directly or indirectly (such as through their parents’ work clothes). Children who have been exposed to asbestos should be monitored for symptoms and undergo proper medical follow-up.
12. What is the difference between palliative care and hospice care?
Palliative care focuses on relieving the symptoms and improving the quality of life of patients with serious illnesses, including mesothelioma. Palliative care can be given alongside curative treatments and can involve pain management, counseling, and other supportive services. Hospice care, on the other hand, is specialized care for patients who are nearing the end of life and are no longer seeking curative treatments. Hospice care can provide comfort and dignity to patients and their families during this difficult time.
13. Can transitional mesothelioma recur after treatment?
Yes, mesothelioma can recur (come back) after treatment, even if the patient has achieved remission (no signs of cancer). The risk of recurrence depends on various factors, such as the stage and location of the cancer, the histology, and the treatment response. Patients who have completed treatment should undergo regular follow-up appointments and scans to monitor for any signs of recurrence.
