Overall and relapse-free survival. Kaplan-Meier estimates of overall (A) and relapse-free survival (B) by disease status at transplantation are depicted. CR1/CR2 indicates complete remission 1 (n = 22) or 2 (n = 14); non-CR, patients with refractory disease (n = 27), untreated relapse (n = 7), or untreated primary disease (n = 1). (C-D) Overall and relapse-free survival was similar for patients who received a transplant from siblings (SIB) or volunteer unrelated donors (VUD) (CR group: SIB n = 22, VUD n = 14; non-CR group: SIB n = 17, VUD n = 18).
