Abstract

Malignant peripheral nerve sheath tumours (MPNST) are rare sarcomas with one of the poorest prognoses of all the soft tissue sarcomas. Information about adjuvant treatment is scarce and not homogeneous for this diagnosis. We analyzed retrospectively the outcome of patients with localized high grade MPNST admitted to our Institute from 1969 to 2008. A review of the literature is also reported. Of 62 evaluable patients, 23 were females and 39 males, median age 39 years (17-71), 22/62 had neurofibromatosis type I. Median follow-up was 54 months (range 12-194). A total of 22/62 are alive; 26 patients had surgery alone, 18 received radiation therapy, 12 received radiation therapy and chemotherapy, and 6 received only adjuvant chemotherapy. The 5-year disease-free survival was 30% and 5-year overall survival was 38%. A positive trend for adjuvant radiation, but not for chemotherapy was observed according to univariate analysis only for disease-free survival and overall survival. Multivariate analysis indicated that primary site, size and surgical margins remained significant for disease-free survival and only site and size were significant for overall survival. New drugs employed successfully in advanced MPNST should be employed also in the adjuvant setting.
