Learn what biphasic mesothelioma is, how it is diagnosed and treated, and what factors affect its prognosis. This article will help you understand this rare and aggressive cancer caused by asbestos exposure.
Biphasic mesothelioma is a type of malignant mesothelioma that has both epithelioid and sarcomatoid cells. It is also known as mixed mesothelioma because it combines features of both cell types. Biphasic mesothelioma accounts for 10-20% of all mesothelioma cases and is caused by exposure to asbestos fibers.
Biphasic mesothelioma can affect different parts of the body, such as the pleura (lung lining), the peritoneum (abdominal lining), the pericardium (heart lining), or the tunica vaginalis (testicular lining). However, it is most commonly found in the pleura or the peritoneum.
The prognosis of biphasic mesothelioma depends on several factors, such as:
- The ratio of epithelioid to sarcomatoid cells
- The location and stage of the tumor
- The patient’s age, health, and performance status
- The treatment options available and chosen
In this article, we will discuss these factors in more detail and provide some tips on how to improve your chances of survival.
1. How Does Cell Type Affect Biphasic Mesothelioma Prognosis?
The cell type of biphasic mesothelioma affects its prognosis because it determines how aggressive and resistant to treatment the cancer is. Epithelioid cells are more common and less aggressive than sarcomatoid cells. They tend to stick together and form well-defined tumors that are easier to remove surgically. They also respond better to chemotherapy and radiation therapy.
Sarcomatoid cells are rare and more aggressive than epithelioid cells. They tend to spread quickly and form irregular tumors that are harder to remove surgically. They also resist chemotherapy and radiation therapy more than epithelioid cells.
Biphasic mesothelioma has both cell types, but in varying proportions. To be classified as biphasic, a tumor must have at least 10% of both epithelioid and sarcomatoid cells. However, some tumors may have more epithelioid cells than sarcomatoid cells, or vice versa.
The prognosis of biphasic mesothelioma improves if it has more epithelioid cells than sarcomatoid cells. This means that the cancer is less aggressive and more responsive to treatment. On average, patients with biphasic mesothelioma that has more epithelial cells live longer than those with more sarcomatoid cells.
2. How Does Location and Stage Affect Biphasic Mesothelioma Prognosis?
The location and stage of biphasic mesothelioma also affect its prognosis because they determine how far the cancer has spread and how much it affects vital organs.
Pleural biphasic mesothelioma affects the lung lining and can cause symptoms such as:
- Difficulty breathing
- Chest pain
- Pleural effusion (fluid buildup in the chest cavity)
- Pleural thickening or plaques
Peritoneal biphasic mesothelioma affects the abdominal lining and can cause symptoms such as:
- Abdominal pain
- Abdominal swelling
- Weight loss
- Bowel obstruction
Pericardial biphasic mesothelioma affects the heart lining and can cause symptoms such as:
- Heart palpitations
- Chest pain
- Pericardial effusion (fluid buildup around the heart)
- Cardiac tamponade (compression of the heart)
Tunica vaginalis biphasic mesothelioma affects the testicular lining and can cause symptoms such as:
- Testicular swelling or lump
- Scrotal pain
- Hydrocele (fluid buildup in the scrotum)
The stage of biphasic mesothelioma indicates how far it has spread from its original location. There are four stages of pleural or peritoneal biphasic mesothelioam according to TNM system:
- Stage I: The cancer is localized within one side of either pleura or peritoneum.
- Stage II: The cancer has spread beyond one side of either pleura or peritoneum but not into nearby lymph nodes.
- Stage III: The cancer has spread into nearby lymph nodes or into other structures within either chest cavity or abdomen.
- Stage IV: The cancer has spread beyond either chest cavity or abdomen into distant organs such as liver, brain, bones etc.
The prognosis of biphasic mesothelioam worsens as it progresses from stage I to stage IV. This means that the cancer has spread more extensively and affects more organs and tissues. The earlier the stage of biphasic mesothelioma, the better the prognosis and the more treatment options available.
3. How Does Treatment Affect Biphasic Mesothelioma Prognosis?
The treatment of biphasic mesothelioma affects its prognosis because it can help slow down or stop the growth and spread of cancer cells, relieve symptoms, and improve quality of life. However, not all treatments are suitable or effective for every patient with biphasic mesothelioma.
The choice of treatment depends on:
- The location and stage of the tumor
- The ratio of epithelioid to sarcomatoid cells
- The patient’s age, health, and performance status
- The patient’s preferences and goals
Some of the common treatment options for biphasic mesothelioma include:
Surgery: This involves removing part or all of the affected lining and nearby tissues or organs. Surgery can be curative (aimed at removing as much cancer as possible) or palliative (aimed at relieving symptoms). Surgery is usually combined with chemotherapy or radiation therapy to prevent recurrence. Surgery is more effective for patients with more epithelioid cells than sarcomatoid cells, as they tend to have more localized tumors that are easier to remove.
Chemotherapy: This involves using drugs that kill cancer cells or stop them from dividing. Chemotherapy can be given before surgery (neoadjuvant) to shrink tumors, after surgery (adjuvant) to kill any remaining cancer cells, or alone (systemic) for advanced cases. Chemotherapy is usually given intravenously (through a vein) or intrapleurally (into the chest cavity). The most common chemotherapy drugs for biphasic mesothelioma are pemetrexed (Alimta) and cisplatin.
Radiation therapy: This involves using high-energy beams that damage DNA and kill cancer cells. Radiation therapy can be given before surgery (neoadjuvant) to shrink tumors, after surgery (adjuvant) to kill any remaining cancer cells, or alone (palliative) for advanced cases. Radiation therapy is usually given externally (from a machine outside the body) or internally (with radioactive seeds implanted near the tumor). Radiation therapy can help reduce pain and bleeding caused by biphasic mesothelioma.
Immunotherapy: This involves using drugs that stimulate the immune system to fight cancer cells. Immunotherapy can be given alone or in combination with other treatments for advanced cases. Immunotherapy is usually given intravenously (through a vein). Some examples of immunotherapy drugs for biphasic mesothelioma are pembrolizumab (Keytruda), nivolumab (Opdivo), ipilimumab (Yervoy), durvalumab (Imfinzi), tremelimumab etc.
Other treatment options for biphasic mesothelioma include:
Targeted therapy: This involves using drugs that target specific molecules involved in cancer growth and survival. Targeted therapy can be given alone or in combination with other treatments for advanced cases. Targeted therapy is usually given orally (by mouth) or intravenously (through a vein). An example of targeted therapy drug for biphasic mesothelioma is bevacizumab (Avastin), which blocks blood vessel formation in tumors.
Palliative care: This involves providing physical, emotional, social, and spiritual support to patients and their families throughout their illness. Palliative care can help improve quality of life, manage symptoms, cope with stress, and make informed decisions about treatment options.
4. How Can You Improve Your Biphasic Mesothelioma Prognosis?
There are some steps you can take to improve your chances of survival if you have been diagnosed with biphasic mesothelioma:
Seek expert medical care: It is important to find a doctor who specializes in treating mesothelioma and has experience with different cell types. A specialist can provide you with an accurate diagnosis, a personalized treatment plan, and access to clinical trials and new therapies.
Explore all your treatment options: It is important to discuss all your treatment options with your doctor and weigh their benefits and risks carefully. You may want to consider getting a second opinion from another specialist before making any decisions about your treatment plan. You may also want to seek alternative or complementary therapies that may enhance your conventional treatments or improve your well-being.
Take care of yourself: It is important to take care of your physical and mental health. You can do this by eating a balanced diet, staying hydrated, getting enough rest, exercising moderately, avoiding smoking and alcohol, managing stress, and seeking emotional support from your loved ones or a counselor. You can also join a mesothelioma support group or a clinical trial to connect with other patients and learn about new treatments.
Seek legal compensation: If you have been diagnosed with biphasic mesothelioma due to asbestos exposure, you may be eligible for financial compensation from the responsible parties. You can file a mesothelioma lawsuit, a claim with an asbestos trust fund, or apply for veterans’ benefits if you were exposed during your military service. Seeking legal compensation can help you cover your medical expenses, lost income, and other damages caused by your illness.
