The COG ANBL0532 trial was designed to assess single vs. tandem autologous stem cell transplantation for patients with newly-diagnosed high-risk neuroblastoma. So why talk about it at ASTRO? Because patients with gross residual disease (>1 cm3) received 36 Gy, a >50% increase from the historical standard of 21.6 Gy. TBL: Rates of local progression of high-risk neuroblastoma were not improved with higher radiation doses. | Liu, ASTRO 2019
