  　View Summary

  Introduction: The nutritional risk index (NRI), calculated using serum albumin levels and body weight ratio is a known prognostic factor in adult hematopoietic cell transplantation (HCT). However, its usefulness in pediatric HCT settings remains unclear. Methods: In a retrospective study, we examined pre-transplant NRI impact on outcomes in 82 pediatric patients undergoing allogeneic HCT. Results: The 2-year non-relapse mortality (NRM) rate was 7.94% (95% confidence interval [CI], 3.05%-19.8%) and 30.8% (95% CI, 16.7%-52.2%) in the high and low NRI groups, respectively (p = 0.0037). Conclusion: We found that poor nutritional status prior to pediatric HCT led to a worse prognosis, including increased NRM. Keywords: pediatrics; prognostic factor; stem cell transplantation
