Surgical perspective on treatment of pediatric undifferentiated sarcoma of the liver

Abstract

Surgical resection and chemotherapy are the mainstay of the treatment for undifferentiated embryonal sarcoma of the liver. Whether neoadjuvant chemotherapy should be systematically performed is a matter of debate; perioperative morbidity and mortality should be carefully weighed against chemotherapy-associated complications. In order to manage undifferentiated embryonal sarcoma of the liver and to allow for accurate outcome analysis, there is a clear need for standardization of disease extent as well as for a risk stratification system, including the PRETEXT grouping system, patient age, and tumor size.
