Is MPNST curable?
Malignant peripheral nerve sheath tumors (MPNST) are aggressive soft tissue sarcomas characterized by high risk of local recurrence and distant metastasis. The only known curative therapy is complete resection. Adjuvant radiation is recommended for larger lesions or those with more aggressive histology.
What is the prognosis for nerve sheath tumor?
The benign tumor has excellent prognosis while malignant tumor has poor prognosis. The prognosis of benign nerve sheath tumor is more favorable as compared to malignant tumor as they are slow in growth and does not have the potential to metastasize.
What is the treatment for a malignant peripheral nerve sheath tumor?
Treatment for malignant peripheral nerve sheath tumors often involves: Surgery. The goal of surgery is to remove the entire tumor and a small margin of healthy tissue that surrounds it. When that isn’t possible, surgeons remove as much of the tumor as they can.
When do you need a nerve sheath biopsy?
In some cases, such as when there are concerns that the tumor may be malignant, the doctor may recommend a biopsy in order to make a diagnosis. A nerve sheath tumor may appear on imaging such as an MRI or ultrasound when a person is being evaluated for one of the symptoms listed above.
Can a tumor on the nerve be removed?

What is the cause of a nerve sheath tumor?
Genetic Cause- An inherited syndrome, neurofibromatosis, increases the risk of malignant nerve sheath tumor. In this condition, the tumor suppressor activity of the cells is reduced, increasing the risk of developing benign as well as malignant tumor.
