Biphasic Mesothelioma: From Diagnosis to Treatment

Biphasic Mesothelioma is a rare and aggressive cancer that starts in the lining of the lungs (Pleural Mesothelioma) or abdomen (peritoneal mesothelioma).

It’s different from other types of mesothelioma because it has both epithelial and sarcomatoid cells. This makes it harder to diagnose, treat, and predict outcomes.

Less than 10% of all mesothelioma cases are biphasic, so it’s important to understand this disease well.

Early detection, the right treatment, and better patient outcomes depend on it.

Biphasic Mesothelioma Demystified

Biphasic mesothelioma stands out for its mix of different cell types.

It has epithelial cells, similar to those lining organs, and sarcomatoid cells, like those found in connective tissues such as bone or muscle .

This mix makes the disease aggressive, often advancing quickly and not responding well to usual treatments used for mesothelioma’s with only one cell type.

The Culprit Behind the Curtain

Asbestos exposure is the main cause of biphasic mesothelioma, like in many other mesothelioma cases.

Asbestos, a mineral widely used in construction and industries in the past, releases harmful fibers when inhaled or swallowed.

These fibers get stuck in the lungs or abdomen, causing long-term inflammation and eventually turning into cancer.

Recognizing the Signs of Biphasic Mesothelioma

Biphasic mesothelioma can be mistaken for other lung or abdominal problems, which makes spotting it early tough. Still, some signs to look for include:

  • Breathing problems like shortness of breath, ongoing cough, or chest pain.
  • Abdominal troubles such as pain, swelling, trouble eating, or weight loss.
  • Feeling generally unwell, like being tired all the time, having a fever, or sweating at night.

Diagnosis Through a Multifaceted Approach

  • Imaging Techniques: Chest X-rays, CT scans, and MRIs provide initial clues about potential abnormalities.
  • Fluid Analysis: Examination of pleural or peritoneal fluid for the presence of cancer cells.
  • Biopsy: Tissue sampling from the affected area, followed by microscopic evaluation for conclusive diagnosis sand determination of cell types.

Treatment Options and their Nuances

Regrettably, there’s no cure for biphasic mesothelioma.But using a mix of treatments can ease symptoms, extend life, and make life better.

The plan depends on:

  • How far the cancer has spread (stage of the disease).
  • The patient’s overall health and how well they can handle treatments.
  • The balance between epithelial and sarcomatoid cells.

Surgical Intervention

Debulking surgery, aiming to remove as much tumor tissue as possible, is sometimes considered, particularly in early stages or for symptom relief.


Powerful drugs target and destroy cancer cells, often given in combination regimens.

However, biphasic mesothelioma often shows reduced susceptibility to these drugs.

Radiation Therapy

High-energy rays target and damage cancer cells, either delivered externally or internally.

While its role in biphasic mesothelioma is still under investigation, it may offer localised control or symptom palliation.

Emerging Frontiers

Using the body’s immune system to fight cancer shows potential for future treatments

Researchers are also looking into targeted therapies, which attack specific molecular problems in cancer cells, as options for managing Biphasic Mesothelioma.

Biphasic Mesothelioma Prevention

Since asbestos exposure is the primary cause, strict regulations and bans on asbestos use are crucial preventive measures.

Additionally, individuals with occupational exposure histories should seek regular screenings to detect mesothelioma at its earliest stages.

Institutions Offering Guidance and Care

The Mesothelioma Applied Research Foundation (MARF) offers detailed info, patient support groups, and financial aid programs.

The National Cancer Institute (NCI) provides scientific info, treatment options, and lists of clinical trials.

The American Cancer Society (ACS) offers patient resources, support groups, and guidance on navigating the healthcare system.

The International Mesothelioma Association (IMA) supports mesothelioma patients and their families worldwide.


If you have ongoing symptoms that might be Biphasic Mesothelioma, see your doctor right away.

With ongoing research progress and access to specialized care, the outlook for people with this tough disease is getting better over time.
