However, the significance of abundant CD34+ in bone marrow transplantation (BMT) remained unclear.MethodsWe retrospectively reviewed 207 consecutive adult patients who underwent their first BMT at Jichi Medical University between January 2009 and June 2021.ResultsThe median nucleated cell count (NCC) and CD34+ cell dose were 2.17 × 108/kg (range .56‐8.52) and 1.75 × 106/kg (.21–5.84), respectively. Compared with 104 patients in the low CD34+ group (below the median), 103 patients in the high CD34+ group (above the median) showed faster engraftment at day +28 in terms of neutrophil (84.6% vs. 94.2%; p =  .001), reticulocyte (51.5% vs. 79.6%; p < .001), and platelet (39.4% vs. 72.8%; p < .001). There were no significant differences in overall survival, relapse, nonrelapse mortality, acute or chronic graft‐versus‐host disease, or infectious complications between the two groups in univariate and multivariate analyses. Low or high NCC had no significant effect on overall survival, nonrelapse mortality, cumulative incidence of relapse and graft‐versus‐host disease, either. While a positive correlation was observed between NCC and the CD34+ cell dose, a high CD34+ cell dose was associated with rapid hematopoietic recovery, even in patients with NCC below the median.ConclusionMeasurement of CD34+ cell dose in addition to NCC was useful for predicting hematopoietic recovery, but seemed to have little influence on the long‐term outcome in BMT. 10.1111/ctr.15313 http://onlinelibrary.wiley.com/termsAndConditions#vor
