Abstract Abstract 3540 Historically, allogeneic hematopoietic cell transplantation (HCT) has been offered only to patients with good performance status and below the age of 60. However, the peak incidence of most hematologic malignancies is above 60 years of age. The introduction of reduced intensity conditioning (RIC) regimens enabled successful allogeneic HCT in patients with considerable comorbidities and older than 60 years. The impact of age on outcome of allogeneic HCT in patients ≥60 years has not been evaluated extensively. We retrospectively analyzed 109 consecutive patients (f=43, m=66) aged≥60 who received allogeneic HCT 2000–2010 at our institution. Median age of the patients was 65 years (range, 60–76). Patients were grouped in two cohorts depending on age: group 1 aged 60–65 years (n=60, median age=63) and group 2 aged 66–76 years (n=49, median age=68). Diagnoses were acute leukemia (AML n=65, ALL n=1), myelodysplastic syndrome (n=14), osteomyelofibrosis (n=7), non-Hodgkin lymphoma (n=9), multiple myeloma (n=8), aplastic anemia (n=1), chronic myeloid leukemia (n=2) and chronic lymphatic leukemia (n=2). At time of HCT, 41 of the patients were in complete remission (CR), 68 in partial remission (PR) (group 1: CR 21, PR 39; group 2: CR 20, PR 29) and 18 patients had a preceding HCT, 14 in group 1. Conditioning regimens were grouped in high (TBI/Bu+Cy, n=5, all group 1), intermediate (FLAMSA, Flu/Mel/BCNU, n=28, group 1=11, group 2=17), low (FLU+alkylans, n=48, group 1=32, group 2=16) and minimal (2GyTBI/Flu, n=28, group 1=12, group 2=16) intensity. Intermediate intensity conditioning was particularly used for high risk patients in PR (25/28). 22 patients were transplanted from matched related (MRD), 46 from matched unrelated (MUD) and 41 from mismatched unrelated donors (MMUD). Kaplan-Meier-estimated 3-year overall survival (OS) was 45% for all patients, 32% for group 1 and 62%, for group 2, respectively (p=0.02), with more patients with high risk constellation in group 1. 3-year OS for patients transplanted with MUD was 57%, with MMUD 46% vs. with MRD 0% (p=0.01). Non-relapse-mortality was 28% for all patients, 40% in group 1 and 12% in group 2, probably due to the higher intensity in conditioning in group 1. The outcomes with intermediate, low and minimal intensity conditioning were comparable, while all patients after high intensity conditioning died. Table 1 describes Kaplan-Meier estimated 3-year-OS and statistical univariate analysis by log-rank test in the different subgroups. Table 1. 3-year OS (in%) All Group 1 Age 60–65 Group 2 Age 66–76 Remission CR 52 p=0.25 31 p=0.76 77 p=0.15 PR 40 32 50 Conditioning high 0 p=0.5 0 p=0.08 – p=0.38 intermediate 52 50 53 low 48 43 57 minimal 45 17 67 Donor MRD 0 p=0.01 0 p=0.06 73 p=0.45 MUD 57 53 65 MMUD 46 40 33 GVHD acute no 18 p=0.003 13 p=0.008 33 p=0.27 ≥II 43 53 58 chronic no 39 p=0.25 36 p=0.70 52 p=0.08 limited 52 30 100 extensive 50 30 67 In group 1 the outcome of minimal conditioning was inferior compared to intermediate and low conditioning while patients in group 2 had a better outcome with minimal vs. low and intermediate conditioning. Incidences of acute GVHD ≥II, limited and extensive chronic GVHD (cGVHD) were 10%, 28% and 13%, respectively. In group 1, acute GVHD ≥II occurred in 13% and cGVHD in 35%, in group 2 in 5% and 41% of the patients, respectively. Acute GVHD ≥II was associated with inferior outcome (3-year OS of 18% vs. 43%, p=0.003) while cGVHD had a positive impact on OS. In group 2 patients with limited cGVHD showed better 3-year OS than patients without cGVHD (67% vs. 52%, p=0.12). Age alone had no major impact on outcome of allogeneic HCT. Patients aged ≥60 seemed to benefit from the use of MUD rather than an older MRD. Chronic GVHD had a positive influence on survival. Our data indicate that the regimen used should be tailored to disease risk and patient performance status. Disclosures: No relevant conflicts of interest to declare.

The Impact

Introduction Novel high-risk groups have been identified in adult ALL, including secondary (sALL) and Philadelphia-like ALL (Ph-like, based on CRLF2, IgH, ABL2, JAK2 and other tyrosine kinase translocations), and those with minimal residual disease >0.1% (MRD+) after induction therapy. Novel targeted therapies are now routinely incorporated into 1st line regimens, including tyrosine kinase inhibitors (BCR-ABL1-pos), rituximab (CD20+) and blinatumomab (Blina) for MRD+. The impact of these novel high risk groups and therapies after alloHCT is unknown; therefore, we evaluated their impact on overall survival (OS), relapse rate (REL), non-relapse mortality (NRM) and acute and chronic GVHD. Methods We evaluated pts receiving 1st Allo-HCT for ALL at Mayo Clinic (Rochester, Phoenix, and Jacksonville) from 2008-2018 for outcomes of interest, specifically the impact of novel therapies and risk groups. Associations of patient factors with outcomes were examined using univariable (UVA) and multivariable (MVA) Cox proportional hazards regression models, where the cause-specific hazard of the given outcome was modeled to account for the competing risk of death. Results We identified 261 consecutive AlloHCT recipients during the study period. Median age at transplant was 48 years (18-72) and 147 (56.3%) were male. The median comorbidity (HCT-CI) score was 2 (0-8). 213 pts (81.6%) had B-lineage ALL, of which 85 (32.6%) were BCR-ABL-pos, 17 (6.5%) Ph-like (identified by FISH), 16 (6.1%) hypoploidy/near triploidy (Hy/Tri), and 67 (25.7%) pre-B ALL NOS. The remaining 48 (18.4%) had T-ALL. 30 pts (11.5%) had sALL (i.e. prior chemo/radiotherapy for another malignancy). HyperCVAD was the most common 1st line regimen (68.2%). 243 (93.1%) pts achieved Complete Remission (CR1) after induction therapy, and 203 (77.8%) were in CR1 at the time of alloHCT. Blina was administered for MRD+ in 14 pts (5.4%), and for relapsed/refractory ALL (R/R) in 13 (27% of R/R pts), 7 of whom received Blina as initial therapy for R/R. Donors were matched unrelated in 149 (57.1%), matched related in 98 (37.5%), and haploidentical in 14 (5.4%). Peripheral blood (PB) grafts were used in 233 (89.3%). 103 (54.5%) were donor:recipient (D:R) sex-matched, and 86 D:R mismatched [47 (24.9%) M:F; and 39 (20.6%) F:M]. Myeloablative conditioning was used for the majority (78.5%) mostly with Cy/TBI (60.5%). Standard GVHD prophylaxis regimens were used. Outcomes Median follow-up after transplant was 22.4 months (0.5-135), and 51 (19.5%) had REL. The 1, 2 and 5-year survival rates were 71.9%, 64.9%, and 54.1%, respectively (Figure 1). Acute GVHD developed in 144 (55.2%) and chronic GVHD in 100 (38.3%). Ph-like ALL, Blina for MRD+, Blina for R/R, sALL and CD20-pos had no independent impact on OS. In contrast, age>60, Hy/Tri, and >CR1 at alloHCT were associated with worse OS in UVA, however, in MVA only pre-B ALL NOS was associated with better OS. Female:male D:R status was associated with inferior OS. Blina for R/R disease was associated with increased risk of REL in UVA [HR 5.26 95% CI (1.33, 20.00), p=0.017], whereas other novel high risk groups had no impact on REL. In contrast, T-ALL, Hy/Tri and >CR1 at AlloHCT were associated with increased REL in UVA, but only T-ALL and Hy/Tri continued to predict for increased REL in MVA. Secondary ALL was associated with increased NRM in UVA [HR 1.96 95% CI (1.07, 3.57), p=0.028], whereas other novel high risk groups had no impact on NRM. In contrast, age>60, >CR1 at AlloHCT and D:R sex mismatch were associated with higher NRM in UVA, but only sex mismatch and >CR1 at AlloHCT were associated with higher NRM in MVA. TBI use was associated with higher risk of acute GvHD (p=0.008) and ATG use with lower risk chronic GVHD (p<0.001). Similarly non-PB grafts were associated with a lower risk of chronic GVHD (p=0.005). Results for OS, REL, NRM, acute and chronic GVHD analysis are shown in Table 1. Conclusion Novel high risk groups (CD20+, Ph-like and sALL) do not appear to adversely impact OS after alloHCT, although sALL was associated with increased risk of NRM. Interestingly, pre-B-ALL NOS appear to be associated with favorable OS. Novel targeted therapies also do not independently predict outcome, with the exception of Blina for R/R ALL which may be associated with REL after subsequent alloHCT (a subgroup for whom novel maintenance strategies should be explored). Our analysis highlights the importance of allo-HCT for novel high risk ALL subgroups.

Abstract Prophylactic transfusion of donor lymphocytes (pDLT) is an attractive form of maintenance therapy after allogeneic stem cell transplantation in patients with high risk of relapse. However, clinical experience is limited, and disease response is often achieved at the expense of severe graft-versus-host disease (GvHD). We here report our data on pDLT in high-risk AML and MDS. Cells were given within a prospective protocol that contained a sequence of chemotherapy, reduced intensity conditioning for allogeneic transplantation, and pDLT (FLAMSA-regimen). For pDLT, patients had to be in CR at least 120 days from transplantation, off immunosuppression for 30 days, and free of GvHD. 22/86 patients alive at day +120 fulfilled the criteria for pDLT. They had been transplanted for refractory or relapsed leukemia (n=9 each) or in CR1 because of unfavorable cytogenetics (n=4). 14 patients had an unfavorable karyotype, 8 with complex aberrations. Reasons for withholding pDLT in 64 patients included cGvHD or prolonged immunosuppression (n=38), refractory or relapsed leukemia (n=15), refusal of patient or donor (n=4 each), a history of grade IV acute GvHD (n=2), and chronic infections (n=3). The median time from transplant to first pDLT was 167 days (range 120–297). Median follow up of transfused patients is 696 days (range 209–1341). Ten patients received 1, 6 patients received 2, and 6 patients received 3 transfusions in escalating doses, containing a median of 1x106, 5x106 and 1x107 CD3+ cells/kg at pDLT 1, 2 and 3, respectively. Reasons for giving less than 3 transfusions were GvHD, relapse or refusal of the patient. Induction of GvHD was the main complication; grade III acute GvHD developed in 1, and chronic GvHD in 7 patients. So far, 5 patients have relapsed despite pDLT. One died of refractory leukemia, whereas 2 achieved secondary CR following adoptive immunotherapy. Two patients are currently under treatment. At present, 18/22 patients are alive and in CR at a median of 423 days post DLT. The current leukemia free survival at two years from first pDLT is 79%. Nineteen patients were complete chimeras at time of pDLT. pDLT converted mixed into complete bone marrow chimerism in 1, but failed in 2 cases. In our experience, pDLT is safe after allogeneic transplantation for high risk AML, when given at low doses and to a selected group of patients. Results are encouraging, and long term survival can be achieved. However, further studies need to define more precisely the contribution of pDLT to the therapeutic effect of the entire procedure.

Abstract INTRODUCTION We retrospectively analyzed the impact on post-relapse survival of selected prognostic factors and salvage therapy (finalized to perform an allo-SCT) in 145 patients (pts) with non-APL AML who had been initially treated with standard induction and risk-adapted consolidation. The aim was to identify factors associated with a better outcome at first relapse. METHODS All pts were at first recurrence following consolidation of CR1 with (i) high-dose Ara-C (HiDAC) multicycle therapy supported by blood stem cells (standard risk, as defined by mixed clinico-cytogenetic criteria) or (ii) allo-SCT in case of high-risk prognostic profile. Median pt age was 55 y (range 21–68). CR1 duration was ≤ 6 months in 49 pts (34%), ranging from 0.6 to 6 mo (median 3.7). 25/68 pts (37%) had an unfavourable cytogenetics (CG), and 8.2 % had MDS-related AML. 96 pts (66%) had received HiDAC and 21 (15%) an allo-SCT according to study design. RESULTS 105 pts (72%) received salvage chemotherapy, 10 pts (7%) underwent directly allo-SCT, while the remaining 30 (21%) received palliation and all of them died. Salvage therapy consisted again of HiDAC alone or in combination with fludarabine or anthracyclines. After reinduction, 52/105 pts (49.5%) achieved CR2 and 15 (14%) died of complications. Altogether, 42 pts (29%, group 1) received an allo-SCT following relapse, 27 (64%) in CR2, 5 beyond CR2 and 10 soon after relapse. Of 20 more pts (14%, group 2) in CR2 but without HLA identical donor, 13 could be given further intensive consolidation therapy. Both groups were comparable regarding adverse prognostic features such as age >55 y, WBC count>50,000/μL, unfavourable CG, presence of FLT-3 ITD, prior allo-SCT and 1st CR lasting ≤ 6 mo. At the end of treatment, 37/42 pts (88%) receiving SCT and all 20 pts (100%) given only chemotherapy were in CR2. Logistic regression analysis showed that intensive treatment without HiDAC at induction (p=0.04) as well as CR1 lasting <6 mo (p=0.01) negatively affected CR2 rate. Median duration of CR2 was 7.5 mo (range 1–49) in group 1 compared to 4 mo (range 1–15) in group 2. Day 100 non-relapse mortality in the 2 groups was 7% and 10%. After a median follow-up of 9.4 mo in group 1 (range 3–49) and 10 mo in group 2 (range 2–65), 2-y OS was 24% and 15.5%, respectively. Notably, 2-y OS in allo-SCT group ranged from 42% in pts ≤ 45 years to 14% in older ones. Moreover, survival was affected by risk category. In fact 2-y OS of 14/37 (38%) standard risk pts undergoing allo-SCT at salvage was 41% vs 17% in 28/108 (26%) comparable high risk pts. Cox regression analysis revealed achievement of CR2 being the only independent prognostic factor related to overall survival (p=0.0001). CONCLUSIONS AML patients receiving intensive chemotherapy including HiDAC at 1st relapse reached a high CR2 rate, regardless of type of prior risk-adapted consolidation. Further intensification with allo-SCT may offer substantial salvage rates to younger standard risk patients, thus adding value to the underlying concept of a risk-oriented first-line therapy.

Abstract Background: Reduced-intensity conditioning (RIC) regimens have led to a dramatic reduction of morbidity and mortality after allogeneic hematopoietic stem cell transplantation (allo-HSCT). The concept of RIC is to deliver adequate immunosuppression with manageable graft-versus-host disease (GVHD) and the eventual development of a potent graft-versus-leukemia effect. Nevertheless, GVHD prophylaxis remains a challenging task after allo-HSCT. While the combination of cyclosporine A (CsA) and a short course of methotrexate (Mtx) after transplantation is considered as the gold standard for GVHD prophylaxis after conventional myeloablative allo-HSCT from HLA-identical siblings, there is no consensus on the optimal preventive GVHD prophylaxis after RIC allo-HSCT. On the other hand, recent and ongoing studies are evaluating a promising GVHD prophylaxis strategy using post-transplantation cyclophosphamide (PTCy). The aim of this study is to evaluate the impact of different GVHD prophylaxis used after RIC allo-HSCT in patients receiving peripheral blood stem cells (PBSC) from unrelated donors for hematological malignancies. Patients and methods: We evaluated 127 consecutive patients with hematological malignancies who received RIC allo-HSCT and were followed in our center between January 2008 and January 2016; 74 (58%) were males, median age was 58 years (range: 18-70), 52 (41%) had acute myeloid leukemia, 36 (28%) myelodysplastic syndrome, 12 (10%) myeloproliferative syndrome, 9 (7%) Non-Hodgkin lymphoma, 9 (7%) chronic lymphocytic leukemia, 6 (5%) multiple myeloma and 3 (2%) chronic myeloid leukemia. At transplantation, 65 (51%) patients were in complete response (CR) or chronic phase (CP). RIC regimen consisted on fludarabine, intermediate doses of IV busulfan and anti-thymocyte golbulins (ATG) (Thymoblobulin) in 56 (44%) patients and a sequential FLAMSA regimen in 71 (56%) patients and who also received similar doses of ATG (Thymoglobulin). PBSC donors were 10/10 HLA matched in 81 (64%) patients and 9/10 HLA mismatched in 46 (36%) patients. Patients were divided according to GVHD prophylaxis into 3 groups: group 1 consisted on CsA alone with 23 (18%) patients, group 2 include patients who received either CsA + mycophenolate mofetil (MMF), n= 64 (50%) or CsA + Mtx, n= 20 (16%) or CsA + cyclophosphamide n= 5 (4%), and group 3 included patients receiving CsA + MMF + tacrolimus n= 15 (12%) patients. Results: After transplantation, all patients in group 1 engrafted after a median of 17 (3-25) days, 81/89 (91%) engrafted in group 2 after a median of 17 (5-58) days and 14/15 (94%) engrafted in group 3 after a median of 16 (9-24) days. We did not observe any significant impact of the type of GVHD prophylaxis on the 100-day incidence of grade II to IV acute GVHD, which occurred in 6/15 (40%), 34/81 (42%) and 7/14 (50%) for the groups 1, 2 and 3 respectively (p=0.18). Grade III-IV acute GVHD occurred in 3 (20%), 24 (29%) and 5 (33%) in the three groups respectively (p=0.11). Similarly, cumulative incidence of 1 year chronic GVHD was not different between groups 1, 2 and 3 reaching 46%, 43% and 46% respectively (p=0.6) among them 3/15 (20%), 18 (22%) and 3/14 (21%) patients had an extensive form. After a median follow-up of 22 months for surviving patients, although there was no significant difference between the three groups in terms of non-relapse mortality, we observed more infection-related mortality with 45% and 83% in groups 2 and 3 respectively compared to 47% in group 1. The cumulative incidence of relapse at 2 years was 22%, 31 and 26% for the three groups respectively (p=0.23). Overall survival rates at two years were 43%, 31% and 44 % for groups 1, 2 and 3 respectively (p=0.42). The multivariate analysis taking into account the type of disease, donor HLA matching, disease status at transplantation, type of RIC and the type of prophylaxis, showed that the incidence of acute GVHD was influenced only by the use of FLAMSA regimen from mismatched donors, HR= 2.2 [1.3-3.1], p=0.05 which had also the same impact on the occurrence of chronic GVHD. Conclusion: Despite its limitations and the need for prospective randomized studies, the results of our study suggest that in the RIC allo-HSCT from unrelated donors, the different GVHD prophylaxis associations lead to similar GVHD outcomes. Patients with more immunosuppressive drugs had a higher incidence of infection-related mortality and in which PTCy could be a better option.

Background: Unrelated cord blood (UCB) transplant (UCBT) is not recommended in patients with thalassemia major (TM) so far. Post-transplant (PT) Cyclophosphamide (PTCy) with long pre-transplant immunosuppression therapy have improved haploidentical peripheral blood (PB) stem cell transplant (haplo-SCT) survival in TM patients but with 2/31 primary rejection. So, we designed a novel dual transplantation of UCBT following haplo-SCTwith PTCy(NF-14-TM-CT protocol). Aim:To improve results of haplo-SCT and UCBT in patients with TM. Patients and method: NF-14-TM -CT protocol was termed as double-insurance dual transplantsincluding a haplo-SCT and an UCBT, in which conditioning regimen consisted of ATG (at -10 to -8 day), Cy (-7), Fludarabine (-6 to -2), Busulfan (-6 to -4) Thiotepa (-3), haplo-PB (0), PTCy (+3, +4) and UCB (+6). PTCy serve as GVHD prophylaxes after haplo-SCT and as conditioning before UCBT. In total 131 patients with TM from three pediatric center in China received NF-14-TM-CT protocolfrom June, 2014 to April, 2019, with a median follow-up of 13 (2-59) months and a median age of 8 (3.5-17) years. Results Final haplo-PB engrafted(group1)in 76 patients with mean PBSC-MNCof 22.49 (±5.36) x108/kgand UCB nuclear cells (NC) of 5.95 (±3.39) x107/kg and final UCB engrafted (group 2) in 55 patients with mean PBSC-MNC of 21.78 (±5.68) x108/kg and mean UCB-NC of. 5.43 (±2.32) x107/kg. The 4-year overall survival (OS), thalassemia-free survival (TFS), graft rejection (GR), and transplant related mortality (TRM) were 97.6%, 96.0%, 1.5%, and 2.4%, respectively (Fig. A), in total. The corresponding rates for group 1 were 98.3%, 96.9%, 1.7% and 1.8% and for group 2 were 95.5%, 93.8%, 4.5% and 1.4%, respectively. No statistic significant difference was found in OS, TFS, GR and TRM, respectively, when comparing group 1 with group 2 (Fig. B. C, D, E).The incidence of grade II-IV acute GVHD, III-IV acute GVHD, mild chronic GVHD, moderate/severe chronic GVHD, VOD, PT cystitisand PT hemolysis of the entire cohort was 16.8%, 6.87%, 9.92%, 1.52%, 4.60%, 31.3% and 14.5, respectively. Summary:Current study proved that the novel CT improved the results of haplo-SCT and UCBT in patients with TM. Disclosures Wing: Miltenyi Biotec: Employment.

Abstract Background: Hematopoietic stem cell transplantation (HSCT) is the only curative treatment for patients with thalassemia major. Majority of the patients undergoing transplants in India belongs to advanced Pesaro risk stratification and 2013 data from India using treosulfan based conditioning for matched related donor transplants (MRD) has showed an event free survival of 78.8 ± 6.0 at 3 years (Mathews et al. Plos One 2013). Advanced age and risk stratification is a deterrent in proceeding with matched unrelated donor (MUD) transplant in India. Since only 25-30 % of patients are likely to get a MRD, MUD transplant is a feasible option in the background of limited life expectancy in patients with thalassemia major. However, there is no data comparing MRD and matched unrelated donor (MUD) transplants from India. Method: This is a retrospective analysis to compare the outcomes between MRD and MUD transplants from a single institution. Events were defined as primary graft failure, graft rejection leading to recurrence of transfusion dependence or death. Results: A total of 123 patients with thalassemia major underwent MUD search in DKMS and DATRI registries. Fifteen (12%) and 13 (10%) patients found 10/10 HLA identical donors respectively and 4 (3%) of them had matches in both the registries. Very few patients underwent NMDP search due to cost constraints. Among the 36 patients who underwent stem cell transplantation, MRD group had 27 patients and MUD group has 9 patients. Base line characteristics of age, sex and Pesaro risk stratification were matched. (Table: 1) Majority of patients belonged to high risk category in both the groups. The conditioning regimens used in both the groups were thiotepa, fludarabine, and treosulfan (TreoFluT). All the MRD non-sibling transplants and MUD transplants also received antithymocyte globulin (ATG) as part of the conditioning regimen. All patients received HLA identical (10/10) grafts. In the MRD group, the stem cell source was 24 (89%), 2 (7%) and 1 (4%) from sibling, parent and 1st cousin respectively. The MUD grafts were procured from 3 different registries DKMS (German) 5 (56%), NMDP (US) 2 (22%) and DATRI (Indian) 2 (22%). Cyclosporine and short course methotrexate were used as Graft versus host disease (GVHD) prophylaxis in all the patients Multiple challenges are involved in the availability and procurement of donor grafts from different registries. A special DCGI (Drug controller General of India) approval needs to be taken for every graft source procured from overseas. The estimated average cost of MRD transplant is 24000 US$ and MUD transplant is 48000 US$ for DKMS and DATRI grafts and 78000 US$ for NMDP grafts. Inspite of lower costs than the western countries, affordability is a major concern even if matched donors are available. Overall survival at 1 year in MRD and MUD groups was 84.3 ± 7.2% and 88.9 ± 10.5% at a median follow up of 20 (0-57) months and 13 (1-31) months respectively (p= 0.799) (Fig:1). The thalassemia free survival at 1 year was 84.3 ± 7.2% and 77.8 ± 13.9% with a median follow up of 20 (0-57) and 12 (1-31) months respectively (p= 0.732). (Fig: 2). Conclusion: Although the incidence of acute GVHD and chronic GVHD incidence are higher in the MUD transplant group, TreoFluT based conditioning for allogeneic stem cell transplantation with both matched related and unrelated donor graft source is a feasible option in beta thalassemia major patients even in high risk category from developing countries.

The Impact

Purpose To evaluate the incidence of and risk factors for basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) in survivors of hematopoietic cell transplantation (HCT). Patients and Methods The impact of patient-, disease-, treatment-, and toxicity-related factors on risk of BCC and SCC was determined in a retrospective cohort study of 4,810 patients who received allogeneic HCT and who survived for at least 100 days. Results Among allogeneic HCT recipients, 237 developed at least one skin or mucosal cancer (BCC, n = 158; SCC, n = 95). Twenty-year cumulative incidences of BCC and SCC were 6.5% and 3.4%, respectively. Total-body irradiation was a significant risk factor for BCC (P = .003), most strongly among patients younger than 18 years old at HCT (P = .02, interaction). Light-skinned patients had an increased risk of BCC (P = .01). Acute graft-versus-host disease (GVHD) increased the risk of SCC (P = .02), whereas chronic GVHD increased the risk of both BCC (P = .01) and SCC (P < .001). Conclusion This analysis suggests that immutable factors, such as age and complexion, have a significant impact on BCC and SCC. However, specific treatment (radiotherapy) and transplantation complications (GVHD) may modify that risk. These additional risk factors suggest the contribution of immunologic mechanism DNA and tissue repair in the development of BCC and SCC. We confirm previous reports that exposure to ionizing radiation increases the risk of BCC but not SCC. Survivors of HCT should be monitored for the development of BCC and SCC and use preventive strategies.

Abstract Background: Allogeneic HSCT is a widely used treatment for children with acute leukemia (AL) either relapsed or at high risk of treatment failure. However, an HLA-identical sibling is available for only 20-25% of patients and an UD can be located in a suitable time only for a portion of the remaining population. HSCT from an HLA-haploidentical relative (haplo-HSCT) is now considered an alternative option, especially in view of the recent insights in graft manipulation. We recently developed a novel method of more selective T-cell depletion based on physical elimination of α/β T cells (ClinicalTrial.gov identifier: NCT01810120), shown to be effective for both preventing graft-versus-host disease (GvHD) and for conferring improved protection against infections in comparison to haplo-HSCT performed through the infusion of positively selected CD34+ cells. The initial results on 40 patients with AL were reported at the ASH Meeting in 2013 (Bertaina et al). We now present the comparison of the outcome of 80 children with AL given haplo-HSCT after α/β T-cell depletion (group 1) with that of patients transplanted from an HLA-identical sibling (group 2) or an UD (group 3) in the same time period. Patients and methods: All patients with AL were transplanted at the Bambino Gesù Children's Hospital in Rome, Italy, between December 2010 and September 2014; 80 patients were included in group 1, 41 in group 2 and 51 in group 3. Patients were offered α/β T-cell-depleted haplo-HSCT in the absence of suitable conventional donor (HLA identical sibling or 10/10 UD evaluated using high resolution typing) or if affected by rapidly progressive disease not permitting time to identify an UD. Clinical characteristics of patients assigned to the 3 groups and those of their donor are shown in Table1. All children were given a fully myeloablative regimen. No group 1 patient was given any post-transplantation GvHD prophylaxis, while patients of group 2 and 3 were given Cyclosporine-A and short-term methotrexate. Group 1 and 3 patients received ATG Fresenius® (4 mg/Kg/day) from day -5 to -3 for preventing both graft rejection and GvHD. Results: All group 2 and 3 patients had sustained engraftment of donor cells, while 1 of the 80 patients included in group 1 experienced primary graft failure and was rescued by haplo-HSCT from the other parent. The cumulative incidence (CI) of acute GvHD was 30%, 41% and 42%, respectively. Remarkably, all children of the group 1 who developed acute GvHD had a skin-only involvement, while 17% and 16.3% of those of group 2 and 3 had either gut or liver involvement (p&lt;0.001). The CI of chronic GvHD was significantly lower in group 1 children than in those of groups 2 and 3 (p=0.02, see also Figure 1-Panel A). None of the 4 group 1 patients experiencing chronic GvHD had the extensive form of the disease, while the CI of extensive chronic GvHD of group 2 and 3 was 8% and 14%, respectively (p=0.01). Four, 1 and 6 children of patients assigned in group 1, 2 and 3, respectively, died for transplant-related causes; the CI of transplantation-related mortality (TRM) in the 3 groups is shown in Figure 1-Panel B. Relapse was the main cause of treatment failure and occurred at a comparable CI in all the 3 groups (see also Panel C of Figure 1). The 3-year probability of Event-Free Survival (EFS) was comparable in the 3 groups (Figure 1 - Panel D). In multivariate analysis, a Total Body Irradiation (TBI)-containing regimen was the only variable favourably influencing EFS of group 1 children (hazard ratio 2.93, 95% Confidence Interval 1.24-6.95). No variable influenced EFS of group 2 and 3 patients. Conclusions: Overall, these data indicate that haplo-HSCT after α/β T-cell depletion is associated with a risk of TRM and leukemia recurrence comparable to that of transplantation from an HLA-identical sibling or an UD, this translating in a similar probability of EFS. In view of the low incidence of chronic GvHD, this transplant option has to be considered a competitive alternative for children with AL in need of an allograft. Table.

Aсute myeloid leukemia (AML) in children aged 0–2 years and aсute lymphoid leukemia (ALL) up to 1 year (i.e., infants) frequently characterize high risk and poor prognosis. Аllogeneic hemopoietic stem cell transplantation (аllo-HCST) is a main curative but toxic option for these patients, and choice of allogeneic donor may be one of the important factor for long-term survival. Aim. To evaluate overall survival (OS), relapse free survival (RFS), transplant related mortality (TRM), "graft versus host" disease free/relapse free survival (GRFS) in infant with acute leukemia underwent allo-HCST from MUD vs haplodonor at 1st or 2nd remission. The study was approved by the Independent Ethics Committee and the Scientific Council of the I.P. Pavlov First Saint Petersburg State Medical University. 34 children with infant acute leukemia: 23 pts with AML (68%) and 11 – with ALL (32%) – underwent allo-HSCT from MUD vs haplo at 1st or 2nd remission between 2004–2018 were analyzed. Median age at allo-HCST – 22 months (6 months – 5 y.o.). HSCT was performed from MUD in 19 (56%) pts (group 1), haplo – 15 (44%) pts (group 2). Myeloablative conditioning received 29 (85%) pts. Reduced intensity conditioning received 5 (15%) pts. Posttransplant cyclophosphomyde (PtCy) was used in 10 (53%) pts in the group 1 and 14 (93%) pts. in the group 2 (p = 0.043). Engraftment was identified in 18 pts (95%) of group 1 and 12 pts (80%) of group 2 (p = 0.28). At the median follow up 3.5 years OS is 79% in the group 1 аnd 73% in the group 2 (p = 0.68). RFS is 79% in the group 1 аnd 67% in the group 2 (p = 0.41). GRFS is 39% in the group 1 аnd 47% in the group 2 (p = 0.5). TRM occurred in 2 pts (11%) of group 1 (due to infectious and toxicity) and no one of the group 2 (p = 0.2). Haplo-HSCT with PtCy is a good alternative to MUD with high efficacy and acceptable toxicity in children with infant acute leukemia at 1st or 2nd remission.

The Impact

Background Evidence regarding the impact of pre-hematopoietic cell transplantation (HCT) marital status on post-HCT outcomes is conflicting. Methods We identified patients, ≥40-years within the Center for International Blood and Marrow Transplant Research registry who received a HCT between January 2008 and December 2015. Pre-HCT marital status was declared as either 1) Married/living with a partner, 2) Single/never married, 3) Separated/divorced, and 4) Widowed. We performed multivariable analysis to determine the association of marital stsatus with post-HCT outcomes. Results We identified 10,226 allogeneic and 5,714 autologous HCT patients with a median follow-up of 37 months (range 1-102) and 40 months (range 1-106) respectively. There was no association between marital status and OS in both allogeneic (p=0.58) and autologous (p=0.17) settings. However, marital status was associated with grade 2-4 acute GVHD (p<0.001) and chronic GVHD (p=0.04). There was an increased risk of grade 2-4 acute GVHD in separated patients compared with married patients [HR 1.13, 95%CI (1.03-1.24)], while single patients had a reduced risk of grade 2-4 acute GVHD [HR 0.87, 95%CI (0.77-0.98)]. The risk of chronic GVHD was lower in widowed patients [HR 0.82, 95%CI (0.67-0.99)] compared with married patients. Conclusions OS post-HCT is not influenced by marital status, but there are associations between marital status and grade 2-4 acute and chronic GVHD. Future research should consider measuring social support using validated scales, patient and caregiver reports of caregiver commitment, and assess health-related quality of life together with health-care utilization to better appreciate the impact of marital status and social support.
