Abstract

The question of the best donor type between haploidentical (HAPLO) and matched-related donors (MRD) for patients with advanced HL receiving an allogeneic hematopoietic cell transplantation (allo-HCT) is still debated. Given the lack of data comparing these two types of donor in the setting of non-myeloablative (NMA) or reduced-intensity (RIC) allo-HCT, we performed a multicentre retrospective study using graft-vs.-host disease-free relapse-free survival (GRFS) as our primary endpoint. We analysed the data of 151 consecutive HL patients who underwent NMA or RIC allo-HCT from a HAPLO (N  =  61) or MRD (N  =  90) between January 2011 and January 2016. GRFS was defined as the probability of being alive without evidence of relapse, grade 3-4 acute GVHD or chronic GVHD. In multivariable analysis, MRD donors were independently associated with lower GRFS compared to HAPLO donors (HR  =  2.95, P   < 0.001). Disease status at transplant other than CR was also associated with lower GRFS in multivariable analysis (HR  =  1.74, P  =  0.01). In addition, the administration of ATG was independently linked to higher GRFS (HR  =  0.52, P  =  0.009). In summary, we observed significantly higher GRFS in HL patients receiving an allo-HCT using the HAPLO PT-Cy platform compared to MRD.
