Abstract The ideal outcome of allogeneic hematopoietic cell transplantation (allo-HCT) is based on survival that is free of morbidity. The most common causes of treatment failure and morbidity after HCT are relapse, GVHD and non-relapse death. A composite endpoint that measures survival free of clinically significant negative events may be a useful way to determine the success of allo-HCT (1). We assessed GVHD and relapse-free survival (GRFS) where the events were acute GVHD grade 3-4, moderate to severe chronic GVHD, relapse or death in 531 consecutive adult patients who received an allo- HCT between 2006 and 2014 at our center. Median follow up of living patients was 46 months (12-123). Patients were treated using standardized supportive care algorithms at our center. Although this was a retrospective analysis, patient characteristics and outcomes including GVHD grading were obtained from our institutional database where they had been prospectively documented. The median age was 52 (18-77) years. 266 (50%) received myeloablative conditioning, and 428 (81%) received PBSC as stem cell source. Donor type was HLA matched related (MRD, n=198, 37%), matched unrelated (MUD, n=205, 39%) and haploidentical using T-replete grafts and post-transplant cyclophosphamide (HIDT, n=128, 24%). 36% of patients had a high/very high Dana farber disease risk index (DRI). The most common indications for transplant were AML (n=197, 37%), MDS/MPS (n=114, 21%), NHL (n=132, 25%) and ALL (n=68, 13%).1 year OS, disease free survival DFS and GRFS were 78%, 64% and 33% respectively. GRFS after MRD, MUD and HIDT was 39%, 27% and 35% respectively, with MRD recipients having a better GRFS than MUD (p=0.004). Regression analysis showed that GRFS at the one year was lower for, patients transplanted before 2011 than those transplanted between 2011 and 2014(27% vs 39%, p=0.0031), high CIBMTR disease risk than low CIBMTR risk (24% vs 39%, p=0.009) and high/very high DRI than low DRI (23% vs 48%, p<0.001). On multivariable analysis, year of transplant before 2011 (HR =1.2, p=0.03), age >= 50 years (HR 1.22, p=0.05), MUD donor (HR 1.3, p=0.004) and high/very high DRI risk (HR 2.05, p<0.001) were all associated with a worse GFRS at one year post HCT. GFRS is an endpoint that is worth investigating in further trials as a marker of successful HCT. These data suggest that GRFS can be predicted by patient age and DRI but not by HCT-CMI. Importantly the GRFS appears to have improved in more recently transplanted patients and MUD donors produce inferior GRFS to MRD whereas haploidentical donors do not. Table 1.

Abstract Introduction There is no standard therapeutic approach for the relapse after allogeneic hematopoietic cell transplantation (allo-HCT). The aim of this paper is to confirm the role of granulocyte colony-stimulating factor (G-CSF) primed donor lymphocyte infusion (DLI) according to the timing of relapse after allo-HCT with limited CD34+ cell dose (<6x106/kg) Methods One hundred ten patients who had relapsed after allo-HCT at Kyungpook National University Hospital from November 2001 to December 2014, including 40 patients who received DLI from cryopreserved cells derived from the original G-CSF primed graft, were retrospectively reviewed. The patients were classified into early relapse or late relapse group by the median time of relapse after transplant. Results The median age at transplant was 38.5 years (range, 17-67 years) and male was 69 patients (62.2%). Primary diseases for allo-HCT included AML/MDS (n=63, 57.3%), ALL (n=32, 29.1%), CML (n=8, 7.3%), and NHL (n=7, 6.4%). Fifty four patients (49.1%) were in CR1 (complete remission), 16 (14.5%) in CR2, and 40 (36.4%) in relapsed and refractory status at the time of HCT. Sixty nine patients (62.2%) received myeloablative conditioning regimen. The median dose of CD34+ cells was 5.06x106/kg (range, 1~20.6x106/kg). Ninety nine percent of patients achieved the neutrophil recovery (> 500x103/mm3 for 3 days) at a median time of 13 days (range 9-24 days). The median time from HCT to relapse was 139 days (range, 21~1801 days). The median relapse free survival (RFS) since HCT was not significantly different according to the dose of CD34+ cells: median 147 days (range, 122-171) and 157 days (range, 87-227) in CD34+ < 6x106/kg and > 6x106/kg, respectively (p=0.249). The median overall survival (OS) since HCT was not significantly different according to the dose of CD34+ cells: median 324 days (range, 272-375) and 262 days (range, 235-288) in CD34+ < 5.06x106/kg and > 5.06x106/kg, respectively (p=0.554).The incidence of chronic GVHD was more frequent in higher CD34+ group (32.9% vs. 48.2%, P=0.042). After relapse, 57 patients (51.8%) were treated with salvage chemotherapy, 13 patients (11.8%) with second allo-HCT, and 40 patients (36.4%) with G-CSF primed DLI. The median number of CD3+T cell was 2.95x107/kg (range, 0.1~5.43x107/kg). Fourteen patients (23.6%) achieved DLI-induced CR, 20 patients progressed, and 6 patients were not evaluable for response. DLI-induced acute GVHD was observed in 25 patients (62.5%) and chronic GVHD developed in 4 patients (10%). The 1-year overall survival (OS) since relapse was not significantly different according to the use of DLI in early relapse group (11.7 +/- 5.3% and 10.0 +/- 6.7%, p=0.663), but in late relapse group, significantly higher in DLI than non-DLI (43.3 +/- 11.3% and 17.1 +/- 6.9%, p=0.021). The patients treated with DLI showed significantly higher RFS in late relapse group (286 days vs. 165 days, p=0.004). The incidence of DLI-induced GVHD did not differ between two groups. Conclusions G-CSF primed DLI after allo-HCT with limited CD34+ cell dose can be feasible and effective option in terms of response, donor convenience and its cost. In the late relapse group, it may replace the second transplantation for the patients with hematologic malignancies lately relapsed after first allo-HCT.
