Role Of High Dose Chemotherapy And Autologous Stem Cell Transplant In Relapsed Ewing'S Sarcoma - A Systematic Review
BLOOD(2017)
Abstract
Introduction: Relapsed Ewing's sarcoma (ES) is an aggressive malignancy with poor survival. Conventional dose salvage chemotherapy (CC) regimens given at the time of relapse led to response rate up to 28-68% with reported event free survival (EFS) of 29% at 2 years and Overall survival (OS) of 49 % at 1 year and 28-31 % at 2 years (Van Winkle, P. et al. 2005, Magnan et al. 2015). High dose chemotherapy (HDCT) with autologous stem cell transplantation (ASCT) given as induction or as part of consolidation treatment after few cycles of CC has shown benefit in improving OS and EFS in single center studies. (McTiernan et al. 2006, Barker et al. 2005) Despite report of its utility, HDCT is not generally used in United states for relapsed ES and a comprehensive search and systemic review was performed to evaluate the benefits of HDCT for this disease.
