Undifferentiated Sarcoma of the Liver

Abstract

Undifferentiated (embryonal) sarcoma of the liver is a rare malignant tumor, most commonly seen in children aged 6 to 10 years. Previously believed to carry a poor prognosis, more recent reports indicate that treatment regimens combining surgical resection and adjuvant chemotherapy can yield long-term, disease-free survival. In this study, we review 5 pediatric patients with undifferentiated sarcoma of the liver treated with a uniform approach of resection followed by adjuvant chemotherapy and radiation when indicated. All 5 patients are disease free in their first remission at a median of 53 months.
