Radiation and chemotherapy are variably employed. The optimal treatment remains uncertain, particularly for unresectable or metastatic disease and patients with neurofibromatosis type 1 (NF-1).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We present data for 58 patients with newly diagnosed malignant peripheral nerve sheath tumors enrolled on the Children\u2019s Oncology Group study ARST0332. Patients were treated with risk-adapted therapy including surgery with or without radiotherapy and ifosfamide and doxorubicin chemotherapy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Most patients had primary tumors that were greater than 5\u2009cm (86%), deep (95%), and invasive (74%), and 10% had distant metastases. Of the patients, 32 (55%) had germline NF-1, and 26 (45%) did not. Among patients, 31 received neoadjuvant therapy, and 22 were evaluable for response with 5 (23%) attaining an objective response, 10 (45%) stable disease, and 7 (32%) progressive disease. Estimated 5-year event-free survival was 87%, 52%, and 0% for the low- (n\u2009=\u20098), intermediate-, (n\u2009=\u200944), and high-risk (n\u2009=\u20096) patients, respectively. In univariate analysis, event-free survival and overall survival differed by sex, presence or absence of metastatic disease, risk group, and achievement of upfront or delayed R0 and\/or R1. There was no difference in event-free survival or overall survival based on germline NF-1 status.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The treatment strategy in ARST0332 achieved excellent outcomes for low-risk malignant peripheral nerve sheath tumors.
