Post-SCT outcome by stem cell source (allogeneic SCT cohort). (A) Post-SCT RFS by stem cell source. At 5 years, the posttransplant RFS rate was 57.1% (95% CI, 44.1-68.2) in patients who received SCT from unrelated donors, 41.6% (95% CI, 30.0-52.4) in those who received SCT from sibling donors, and 38.5% (95% CI, 14.0-62.8) in those who received CB-SCT (P = .22). (B) Post-SCT OS by stem cell source. At 5 years, the posttransplant OS rate was 61.7% (95% CI, 48.7-72.3) in patients who received SCT from unrelated donors, 52.3% (95% CI, 40.1-63.2) in those who received SCT from sibling donors, and 53.9% (95% CI, 24.8-76.0) in those who received CB-SCT (P = .52).
