With recent rapid improvements in neonatal intensive care, the limit of viability has shifted downward to 22–23 weeks' gestation. The younger the gestational age of preterm infants, the higher the risk of survival despite severe neurodevelopmental impairments. For infants born at 22–23 weeks' gestation, the limit of viability, neurodevelopmental outcomes, and survival rates may be determined by the quality of... |
Question: This study aimed to elucidate the outcomes of high-risk neuroblastoma (HR-NB) patients treated with high-dose chemotherapy and stem cell rescue without immunotherapy. Finding: The 5-year overall survival and event-free survival rates were 45.1% and 40.4%, respectively. Meaning: High-dose chemotherapy plus stem cell rescue followed by cis-retinoic acid for 12 months is well tolerated and could improve survival in patients with HR-NB in limited resource settings. |
