Objective:
To analyze the correlation between early lymphocyte count (lymphocyte count on day 30, LC30) post-allogeneic hematopoietic stem cell transplantation (allo-HSCT) and transplant prognosis in leukemia patients.
Methods:
The data from 124 consecutive patients undergoing allo-HSCT for leukemia from January 2003 to April 2011 was analyzed retrospectively. LC30 post-allo-HSCT correlated with 5-year overall survival (OS), 5-year relapse rate (RR), 5-year nonrelapse mortality (NRM), accumulative rate of acute graft versus host disease (aGVHD) and chronic graft versus host disease (cGVHD) was studied.
Results:
Univariate analysis indicated that patients with LC30 ≥ 0.40×10(9)/L had higher 5-year OS than those with LC30 < 0.40×10(9)/L \[(62.2 ± 5.8)% vs (37.0 ± 8.6)%, P = 0.003\], lower 5-year RR\[(13.9 ± 4.7)% vs (32.0 ± 8.4)%, P = 0.027\], lower 5-year NRM \[(31.3 ± 5.8)% vs (45.0 ± 9.3)%, P = 0.048)\], and higher cGVHD cumulative incidence \[(82.9 ± 4.6)% vs (62.7 ± 11.1)%, P = 0.042)\]. Multivariate analysis also suggested that LC30 was associated with 5-year OS, 5-year RR, 5-year NRM, and cGVHD cumulative incidence. At the same time disease risk stratification was associated with prognosis.
Conclusions:
Early lymphocyte count (LC30) post-allogeneic hematopoietic stem cell transplantation in leukemia is highly associated with prognosis, which can be the independent prognosis index after allo-HSCT in leukemia and can identify a group of patients who might be suitable candidates for early interventions treatment.
