Hepatic sinusoidal obstruction syndrome (SOS) has been rarely studied after haploidentical donor (HID) allogeneic hematopoietic stem cell transplantation (allo-HSCT). We performed a retrospective multicentre study on patients with SOS after allo-HSCT in China. The incidence, risk factors, and outcomes were compared between HID HSCT and matched related donor (MRD) HSCT. SOS developed in 0.4% of patients (HIDs: 0.4%, MRDs: 0.5%, p = 0.952) at a median time of 21.50 days (range, 1-55) after allo-HSCT (HIDs: 24 days, MRDs: 20 days, p = 0.316). For patients diagnosed with SOS, the 2-year cumulative incidence of relapse was 22.7% and 22.4% in patients receiving HID and MRD transplantation, respectively (p = 0.584). Overall survival (OS) at 2 year was 10.4% and 38.5% in the two groups (p = 0.113). The transplant-related mortality (TRM) at 100 days was 60.9% in the HID group and 38.5% in the MRD group (p = 0.178). According to the multivariate analyses, significant independent risk factors for the occurrence of SOS were delayed platelet engraftment (p = 0.007) and advanced disease status at the time of HSCT (p = 0.009). The outcomes of SOS after HID HSCT are similar to those after MRD HSCT.
