White blood cell recovery after allogeneic hematopoietic cell transplantation predicts clinical outcome.

ABSTRACT: To determine whether outcome after allogeneic hematopoietic cell transplantation (HCT) could be estimated by using peripheral white blood cell count (WBC) as a metric that integrates several aspects of HCT recovery, we conducted a retrospective study of 1,109 adult patients who underwent first allogeneic HCT from 2003 through 2009. WBC at 1-3 months after HCT was categorized as low (<2), normal (2-10), and high (>10 × 10(9) cells/L). Overall survival (OS) and progression-free survival (PFS) were lower for patients with low or high WBC at 1-3 months after HCT (P < 0.0001). We developed a predictive three-group risk model based on the pattern of WBC recovery early after HCT. Five-year OS was 47, 30, and 15% (P < 0.0001) and 5-year PFS was 39, 22, and 14% for patients in the three different r
