What is a Malignant Peripheral Nerve Sheath Tumor (MPNST) ?

A malignant peripheral nerve sheath tumor (MPNST) is a rare soft tissue sarcoma. In MPNST, there are cancerous tumors in the sheaths or layers of covering tissue of nerves in your peripheral nervous system. You may have this kind of tumor in your arms and legs, but it can also be in your pelvis, abdomen, head, and neck. Surgery can remove tumors and cure the disease, but the tumors usually come back (recur).

What are the symptoms of a malignant peripheral nerve sheath tumor?

MPNSTs arise wherever you have peripheral nerves, but they most often occur in areas such as your arms and legs. They can occur in your pelvis, chest, abdomen, or head and neck. MPNSTs can cause:

• A growth under your skin that continues to grow. These tumors can be as small as a pea (about 2 centimeters) or as big as a grapefruit (about 10 cm).
• Pain (particularly if you have NF1).
• Paresthesia (tingling).
• Loss of strength in your arms and legs.

What leads to MPNST?

Research indicates neurofibromatosis type 1 causes 50% of malignant peripheral nerve sheath tumors. Other reasons include:

• Radiation therapy: Approximately 10% of individuals with MPNST are given radiation therapy for other health problems.
• Genetic mutations: Researchers have identified multiple genetic mutations that convert regular nerve sheath cells into abnormal cells that proliferate and form tumors.
• Certain neurofibromas: People with plexiform neurofibromas have an increased risk for MPNST.

How is a malignant peripheral nerve sheath tumor diagnosed?

A healthcare provider will perform a physical exam and assess your overall health. This includes a review of your medical history, family history, and symptoms. They may do:

• Imaging tests: Providers may do magnetic resonance imaging (MRI) and positron emission tomography (PET) scans.
• Biopsy: Your provider might perform a biopsy to take tissue for a medical pathologist to view under a microscope.
• Genetic tests: If you have a malignant peripheral nerve sheath tumor, your provider might suggest you and close family members get genetic tests to see if you or they have neurofibromatosis type 1 (NF1) or neurofibromatosis type 2 (schwannomatosis), another kind of nerve sheath tumor.

What are the treatments for MPNST?

Health professionals usually perform surgery to take out an aggressive peripheral nerve sheath tumor. Surgery can't be done in some individuals who have:

• Tumors that are 5 cm or more in size.
• Metastatic tumors.
• Tumors are very complicated networks of nerves that may be damaged in the process of surgery.

Health professionals can treat MPNST by using surgery with chemotherapy or radiation therapy. Professionals can perform radiation therapy prior to or after surgery.

Researchers are investigating immunotherapy or targeted therapy as new or other potential treatments. If you have a malignant peripheral nerve sheath tumor, you might consider speaking with your provider about joining a clinical trial that's evaluating new treatments.

What are the possible complications or side effects of treatment?

Surgery can lead to the following complications:

• Reaction to general anesthesia.
• Bleeding too much (hemorrhage).
• Pain.
• Surgical scars.
• Surgical wound infection.

Treatments such as chemotherapy or radiation can lead to side effects, such as:

• Diarrhea.
• Fatigue.
• Nausea and vomiting.

What is the prognosis for a person with MPNST?

Your prognosis is what your health care team thinks will occur after you complete treatment. They use the following factors to make MPNST prognoses:

• NF1 status: The prognosis for individuals with NF1 who have these tumors is worse than the prognosis for individuals without NF1.
• Tumor grade: Pathologists group tumors as high-grade or low-grade, depending on how the cells look under a microscope. High-grade tumors contain cancer cells that grow extremely fast and tend to spread.
• Tumor size: MPNSTs can grow up to 10 centimeters. Large tumors are generally harder to remove surgically.
• Metastasis: Tumors that have spread from where they originated are harder to treat.

As you can see, several things can impact your prognosis, and not all of the items listed will pertain to you. Have your doctor explain your prognosis to you. They understand your case and are your best source of information.

MPNST survival rates

Survival rates are statistics based on someone else's outcome with malignant peripheral nerve sheath tumors. Since these tumors don't occur that often, the experts can't make estimates easily. The National Cancer Institute (U.S.) says that between 23% and 69% of individuals with MPNST were alive after five years following their diagnosis. That's quite a range, so it might be a good idea for you to get an opinion from your doctor about what they think will happen in your case.

How can I take care of myself?

If you have a malignant peripheral nerve sheath tumor, you're facing an uncommon cancer that usually recurs following treatment. Listed below are a few programs that might be helpful:

• Palliative care: When you receive palliative care, you work together with a group of specially qualified providers who can assist you with MPNST signs and side effects of treatment. More than this, they might be emotional support.
• Survivorship from cancer: Cancer is a journey. Cancer survivorship programs guide you through cancer, from diagnosis and treatment to knowing what to do if cancer returns.
