Abstract

Poor platelet graft function (PPGF) is a significant complication after allogeneic hematopoietic stem cell transplantation (allo-HSCT). However, no optimal treatment has been recommended. This study investigated aspects of platelet recovery after allo-HSCT, including prognostic value and the effect of recombinant human thrombopoietin (rhTPO). We retrospectively analyzed 275 patients who received allo-HSCT in our center. Of them, 135 (49.1%) patients had good platelet graft function (GPGF) and 140 (50.9%) had PPGF. The latter included 59 (21.5%) patients with primary PPGF and 81 (29.4%) with secondary PPGF. Multivariate analysis showed that male gender (P = .024), lower CD34+ cell count (P = .04), and no use of rhTPO (P <.001) were associated with PPGF. The 3-year overall survival rate of patients with PPGF (58%) was significantly less than that of patients with GPGF (82%; P <.001). We further analyzed the effect of rhTPO on prognosis of patients after allo-HSCT. Although no advantage was apparent when analyzing the entire cohort, for patients with myelodysplastic syndromes and aplastic anemia, rhTPO was associated with a significant survival advantage (P = .014).
