PERIPHERAL NERVE CANCER

ALTERNATE NAMES

Malignant Peripheral Nerve Sheath Tumor; Malignant Neurilemmoma; MPNST; Sporadic Neurofibromatosis Type I; Neurofibromatosis Type I; Malignant Neurofibrosarcoma; Malignant Schwannoma; Malignant Tumor of the PNS; Malignant Neoplasm of the PNS; Malignant PNS Tumor; Malignant PNS Neoplasm; Neurosarcoma

DESCRIPTION

Peripheral Nerve Cancer is a rare malignant tumor that develops in the tissue (sheath) covering the peripheral nerves. The peripheral nervous system includes the nerves that travel from the brain and spinal cord (central nervous system) to other parts of the body. The nerve sheath is the soft tissue that covers the nerve. This type of cancer occurs most commonly along the nerves that run from the buttocks to the legs (sciatic nerves), neck to the arms or within the pelvis. Peripheral Nerve Cancer that is metastatic or recurrent indicates that the malignant tumor has spread to other parts of the body, and has come back after treatment. This type of cancer generally occurs in adulthood between the ages of 20 and 50 years of age and may occur in childhood.

DIAGNOSTIC TESTING, PHYSICAL FINDINGS, AND ICD-9-CM CODING

Diagnostic testing: Diagnostic testing for peripheral nerve cancer include MRIs, X-rays, CT scans, PET scans, and bone scan to determine the location, size, and shape of the tumor and metastasis. The only definitive diagnosis of peripheral nerve cancer is a biopsy of the tumor.

Physical findings: Most peripheral nerve cancers do not present with neurological symptoms.

ICD-9: 237.7

237.9

ONSET AND PROGRESSION

Peripheral nerve cancers are highly aggressive tumors. The prognosis for people with unresectable tumors (tumors that cannot be surgically removed) is poor. Survival rates vary depending on the location and extent of the tumor, including any metastasis.

TREATMENT

Malignant peripheral nerve cancers are aggressive tumors that require a combination of surgery, chemotherapy or radiation. Complete resection of the tumor carries the longest survival rate.

SUGGESTED PROGRAMMATIC ASSESSMENT*

Suggested MER for evaluation: A pathology report of the tumor biopsy and of any metastasis. If a pathology report is unavailable, a surgical report or radiological studies especially X-rays, MRI scans, CT scans or PET scans may be substituted.
