MPNST is an aggressive tumor for which complete surgical resection is the mainstay of successful treatment. Postoperative radiotherapy may have a role in improving local control in patients with minimal residual tumor. The reported responses to primary chemotherapy suggest that it may be effective in patients with tumor considered unresectable at diagnosis.

The present findings do not support the usefulness of general screening for neuroblastoma at one year of age.

Clinical group, tumor size, and invasiveness are important prognostic factors. Multicenter randomized clinical trials are needed to determine both the effect of chemotherapy on survival and the necessity of local radiotherapy in patients with completely resected tumors.
