Causes
MPNSTs are rare cancers that develop in the protective lining surrounding nerves (sheath). MPNSTs are associated with genetic conditions like neurofibromatosis type 1 (NF1) and radiation exposure, although the exact cause is often unknown.
Symptoms
MPNSTs may cause the following symptoms:
-
An area of persistent pain that may worsen over time.
-
Under the skin, there is swelling or a lump.
-
The affected limb or area is numb or weak.
-
Changing sensations, such as tingling or burning.
-
An area of muscle weakness or loss of function.
-
MPNSTs near the spinal cord may cause bowel or bladder dysfunction in rare cases.
Diagnosis
MPNSTs are typically diagnosed by:
-
Examined for lumps, changes in sensation, and muscle function, a healthcare provider conducts a physical examination.
-
An MRI or CT scan may be performed to determine the size and location of the tumor.
-
A tissue sample (biopsy) may be taken from the suspected tumor site and examined under a microscope.
-
In cases of NF1 or other genetic conditions associated with MPNSTs, genetic testing may be recommended.
Treatment
MPNSTs are often treated with a combination of therapies:
-
In most cases, surgical removal of the tumor is the most effective treatment option. However, if the tumor has infiltrated nearby structures or nerves, complete removal may not be possible.
-
Before or after surgery, radiation therapy may be used to shrink the tumor, kill remaining cancer cells, or relieve symptoms.
-
For advanced or metastatic MPNSTs, chemotherapy may be recommended to slow tumor growth and improve symptoms.
-
Therapy that targets and inhibits the growth of cancer cells can be used in cases where standard treatments are ineffective, such as targeted therapies.
Prevention
MPNSTs are often associated with genetic conditions such as NF1, so prevention strategies may include:
-
Individuals with a family history of NF1 or other genetic conditions associated with MPNSTs may benefit from genetic counseling.
-
Monitoring and regular follow-up appointments with healthcare providers may help detect MPNSTs early, especially in individuals with NF1 or other predisposing conditions.
-
Maintaining a healthy lifestyle, including regular exercise, a balanced diet, and avoiding exposure to environmental toxins, can help reduce the risk of cancer development.
Conclusion
While treatment options are available for peripheral nerve sheath tumors, early detection and intervention are crucial to improving outcomes. It is possible for individuals to receive an appropriate diagnosis and treatment for MPNSTs if they understand the causes, recognize the symptoms, and seek immediate medical attention. In addition, individuals with genetic predispositions to MPNSTs should monitor their symptoms closely and undergo regular screenings as recommended by their healthcare providers.
