Overview

In general Malignant peripheral nerve sheath tumor is known to have high metastatic potential and poor prognosis..[1] long-term outcomes vary widely across multiple series, with 5-year survival ranging between 15% and 50%. Large tumor size at presentation (typically >5 cm) has been the most consistently determined adverse prognostic factor.

Complications

  • A common complication of malignant peripheral nerve sheath tumor is metastasis.
  • Metastasis occurs in about 39% of patients, most commonly to the lung.[2]

Prognosis

  • Prognosis of malignant peripheral nerve sheath tumor is generally poor.[1]
  • Features associated with poor prognosis include a large primary tumor (over 5 cm across), high grade disease, co-existent neurofibromatosis, and the presence of metastases.[2] Malignant peripheral nerve sheath tumor is extremely threatening in NF1.[3]
