Understanding Peritoneal Mesothelioma
Peritoneal mesothelioma is a rare and often misunderstood cancer that forms in the lining of the abdomen (the peritoneum).
While hearing a peritoneal mesothelioma diagnosis can feel overwhelming for patients and loved ones, it is the type of mesothelioma with the most promising outcomes.
Advancements in treatments including surgery combined with heated chemotherapy (HIPEC), have significantly improved survival rates, offering real hope to patients and their families.

The 4 Stages of Peritoneal Mesothelioma
Unlike pleural mesothelioma, peritoneal mesothelioma does not have a formal four-stage system.
Instead, many specialists use the Peritoneal Cancer Index (PCI) to evaluate the extent of cancer spread within the abdomen, which helps guide treatment options.
Peritoneal mesothelioma has more available treatments and overall better outcomes when detected early, while the cancer remains small and localized.
Acting quickly after a diagnosis is necessary to maximize treatment options.

Peritoneal Mesothelioma Survival Rates
Survival rates for peritoneal mesothelioma vary widely based on many key factors, including the cancer spread at diagnosis, cell type, and the patient’s overall health.
While a peritoneal mesothelioma prognosis can feel challenging, early detection and advancements in treatment options have led to improved outcomes for many patients. Innovative therapies and personalized treatment plans offer hope.
The average survival rates for peritoneal mesothelioma across the U.S. are:
• One-year survival rate: 92%
• Three-year survival rate: 74%
• Five-year survival rate: 65%
• Ten-year survival rate: 39%
But please note: survival rates are just an average and do not take into account personalized treatments.
One inspiring example is the longest-known peritoneal mesothelioma survivor, who lived over 25 years after being given only a few weeks to live.

It is caused by exposure to asbestos, a harmful mineral once widely used in construction and manufacturing..
Peritoneal mesothelioma often develops decades after asbestos exposure, and while it can feel overwhelming, advancements in treatment offer hope for many patients and their families.
The other types of mesothelioma are:
• Pleural mesothelioma (lungs): The most common type of mesothelioma affecting the chest and lungs
• Pericardial mesothelioma (heart): A very rare type which develops around the heart
• Testicular mesothelioma (testes): The rarest type, affecting the lining of the testes.
Knowing the type of mesothelioma is important as it can help you determine the best treatment options available and which specialists to see.
Before a biopsy, doctors often use imaging tests like X-rays, CT scans, or MRIs to detect abnormalities and determine the best area for tissue sampling.
The most common biopsy method for peritoneal mesothelioma is a laparoscopy, where a thin flexible instrument with a light and camera (a laparoscope) is inserted into the abdomen to collect tissue samples for an accurate diagnosis.
If you or a loved one has been diagnosed with mesothelioma, it’s important to seek expert guidance as soon as possible. Early diagnosis offers a wider range of treatment options and can improve outcomes.
Peritoneal mesothelioma is a rare and complex disease and consulting a specialist can provide clarity, reassurance, and confidence in your next steps.
A second opinion may also introduce new treatment options or approaches that better fit you and your family’s needs.
But you’re not alone—financial assistance is available. Common options include legal claims for asbestos exposure, veterans’ benefits, and support from insurance or financial aid programs.
You can call our number and one of our patient advocates will help you discover what’s available for you and we’ll do our best to support you in reducing your financial stress and burden.
Your doctor can likely help provide a referral or call us and our patient advocates can help connect you to the peritoneal mesothelioma specialists best suited for you or your loved one’s specific needs.
This exposure puts veterans at a higher risk of developing mesothelioma, a disease that can take decades to appear after initial exposure.
Veterans account for about 30% of all mesothelioma patients. Fortunately, there are additional veterans benefits and specialized care programs designed to support veterans and their families through this difficult journey.
Please call us if you need answers to mesothelioma veteran related questions.
