Your QuestionI was diagnosed with a malignant peripheral nerve sheath tumor in my right thigh. The tumor was taken out surgically. Surgery was followed by 30 sittings of radiation therapy. Several months later, a lump was felt on top of the scar from the first surgery and tests confirmed the lump was the same kind of tumor. Again, the tumor has been removed surgically and chemotherapy is needed. Other tests suggest the tumor has spread to the lungs. What is the prognosis for this type of tumor?

Malignant peripheral nerve sheath tumors (MPNST) are aggressive tumors. The chance of surviving a diagnosis of MPNST depends on the size and location of the tumor; people who have a small tumor tend to survive longer than those with a large tumor, and people with a tumor in the arms or legs tend to survive longer those with a tumor in the head and neck regions. Also, MPNSTs that are treated when they first occur have a better prognosis than when the tumor has regrown after initial treatments (recurred) or spread to distant parts of the body (metastasized). One study of 140 patients found that 26% of individuals diagnosed with MPNST were living 10 years after the initial diagnosis. Of those patients who developed a metastasis, 8% were living 10 years after the initial diagnosis.
