Cell Death Protein

Programmed cell death protein-1 (PD-1) is an inhibitory co-receptor required for regulating immune responsiveness and maintaining immune homeostasis. As PD-1 can be released as bioactive soluble molecule, we investigated the clinical significance of soluble PD-1 (sPD-1) after allogeneic hematopoietic stem cell transplantation (HSCT) regarding graft-versus-host disease (GvHD), relapse, and overall survival (OS) in a mono-centric cohort of 82 patients. Compared to pre-HSCT and to healthy controls, post-HSCT sPD-1 plasma levels were significantly increased during an observation time of three months. Univariate analysis revealed that low sPD-1 plasma levels at month one, two or three post HSCT were associated with acute GvHD grade III-IV, the onset of moderate/severe chronic GvHD (cGvHD) and inferior OS, DFS, and TRM, respectively. No relationship was detected to relapse rates. sPD-1 plasma levels were significantly increased in ATG-treated patients compared to ATG-untreated patients. Multivariate analysis revealed that a low sPD-1 plasma levels status at one or two month(s) after HSCT is an independent indicator for inferior OS, DFS, or TRM. A low sPD-1 plasma levels status at month three post HSCT is predictive for the onset of moderate/severe cGvHD. Thus, our study pinpoints the soluble inhibitory co-receptor PD-1 as a promising candidate molecule for the prediction of clinical HSCT outcome.

Abstract Purpose: The role of haploidentical hematopoietic stem cell transplantation (haplo-HSCT) therapy for refractory or relapsed (R/R) aggressive non-Hodgkin lymphoma (NHL) patients was still unknown. In this study, we aimed to explore the clinical outcome of R/R aggressive NHL patients received haplo-HSCT treatment. Patients and Methods: 23 R/R aggressive NHL patients who had undergone haplo-HSCT in our center between February 2006 and October 2015 were retrospectively analyzed, and 25 R/R aggressive NHL patients who received HLA-matched HSCT at the same period were also involved in this study. All patients received myeloablative conditioning (MAC) regimen, and antithymocyte globulin, cyclosporine A, mycophenolate mofetil and short course of methotrexate were used as graft-versus-host disease (GVHD) prophylaxis. 12 patients had experienced autologous HSCT prior to allo-HSCT. Results: The median age of the total 48 patients was 33 (16-58) years old, and there were 33 males and 15 females in the total cohorts. The diagonosis were as following: 16 (33%) diffuse large B cell lymphoma and 22 (46%) peripheral T cell lymphoma. There were no difference in sex, age at transplantation, histologic diagnosis, aaIPI score, previous ASCT and conditioning regime between HLA-matched HSCT and Haplo-hsct groups. 44 patients had achieved engrafment, and the median times to neutrophil and platelet recovery were 12 and 15 days, respectively. Incidences of grade 3-4 acute GVHD were 18.3% in haplo-HSCT group and 16.7% in HLA-matched HSCT groups(p=0.87), while 2 years cumulative incidences of chronic GVHD in these two groups were 43.5% and 36.7% (P=0.68). For 16 patients who had chemoresistant disease at transplantation in haplo-HSCT group, four patients achieved complete remission, and ten patients achieved partial remission, while the other two patients experienced disease progression at 21 days and 37 days, respectively. With a median follow-up of 25 months, 12 patients experienced disease recurrence or progression in haplo-HSCT. And four patients died of transplantation related mortality: infection (n=2); acute GVHD (n=1) and multi-organ failure (n=1). There were no differences in overall survival (OS) rate at 2 years (52.8% vs 57.0%, P=0.85) and 2 years progress free survival (PFS) rate (52.7% vs 56.9%, p=0.73) between the haplo-SCT and HLA-matched SCT groups. Multivariate analyses suggested that old age (>45 years)(p=0.02), primarychemorefractory (p=0.04)and occurrence of grade3-4 aGVHD (p=0.01) may contribute to poor prognosis. Conclusion: Haploidentical hematopoietic stem cell transplantation withmyeloablative conditioning regimenachieved satisfactory outcome with acceptable side-effects. This approachcan be a feasible and acceptabletherapy for young patients withR/R NHLwho have no access to a HLA-matched donor. Figure Comparison of outcomes after haplo-SCT and HLA-matched SCT.

Abstract Allogeneic hematopoietic stem cell transplantation (HSCT) can cure adults with hematologic malignancies, but results in significant morbidity and mortality. Graft-vs.-host disease (GVHD) is a major complication; attempts to reduce the risk of GVHD include selecting donors based on several characteristics, including parity, a criterion which has been controversial. This retrospective cohort study using data from the Center for International Blood and Marrow Transplant Research (CIBMTR) is the first multi-center analysis of the effects of donor and recipient parity on outcomes of HSCT in the modern transplant era. Methods: We studied patients at least 18 years old who received a non-T-cell-depleted, myeloablative HLA-identical sibling HSCT between 1995 and 1999, for acute lymphoblastic or myelogenous leukemia or chronic myelogenous leukemia. The study endpoints included acute and chronic GVHD, overall survival, and relapse. There were 2,626 patients who met inclusion criteria and had complete information on both donor and recipient pregnancy status. Donors and recipients were categorized as: males, nulliparous females, or parous (one or more pregnancies) females. Analysis: We compared all possible combinations of donor and recipient pregnancy status (9 groups in total); the reference group was male donor/male recipient pairs. Multivariate Cox proportional hazards regression was used to adjust for other prognostic factors. Because multiple groups were compared, significant p-values were considered to be less than or equal to 0.006. Results: After controlling for important patient-, disease-, and transplant-related covariates, the risk of chronic GVHD was significantly increased in parous female donor/male recipient pairs (HR 1.56, 95% CI 1.23 – 1.94, p < 0.0001). Neither donor nor recipient parity had an impact on overall survival, acute GVHD, or relapse risk. Conclusions: This multi-center retrospective registry study showed that parous female donors resulted in a significantly increased risk of chronic GVHD in male recipients, but without concomitant reduction in relapse. Thus, H-Y antigens may be important targets of GVHD, but not of a graft-versus-leukemia effect. As when selecting unrelated donors, avoidance of parous female donors, particularly for male patients, in HLA-identical sibling transplants is recommended when possible.

Abstract Background: The optimal regimen for allogeneic stem cell transplantation with a reduced-intensity conditioning regimen (RIST) needs to be established. Therefore, we retrospectively reviewed data of 84 patients who underwent RIST using 180 mg/sqm fludarabine and 8 mg/kg busulfan (Flu/Bu8). All patients received mobilized blood stem cells from a related donor between Nov. 2000 and Jun. 2005. Patients and Methods: The median age of the patients was 53 years (range, 25–65). The diagnosis included 42 AML/MDS, 34 lymphoma and 8 others. Sixty-nine patients (82%) had high-risk diseases, including 56 (81%) in non-remission status before RIST. All were serologically 6/6 matched pairs, except for one who had a 5/6 match. For GVHD prophylaxis, 61 used cyclosporine A (CSP) alone, 21 used CSP + methotrexate (MTX), and 2 used some other compounds. Results: The engraftment kinetics were remarkable since all of the patients successfully engrafted at a median of 11 days (5–24 days), with no late graft rejection. Toxicities of grade 2 or 3 according to CTCAE v.3 were observed at minimal frequencies, i.e. 38 mucosal, 35 hepatic, 13 GI tract, 12 renal, 2 cardiac, 1 pulmonary, 19 febrile neutropenia, and 9 documented infections, and there were no grade 4 toxicities. The administration of MTX increased the incidence and severity of stomatitis (P=0.05). The cumulative incidences of grade II–IV and III–IV acute GVHD were, respectively, 50% and 29%, and 76% experienced chronic GVHD. Seventy-three patients (87%), including 38 of the 56 patients who were not in CR at the time of transplant, achieved partial or complete remission. The median follow-up of surviving patients was 1349 days (34–1981 days), and the day-100 mortality was 11% (disease progression 6% and non-relapse mortality [NRM] 5%). The 5-year overall and progression-free survival rates were 36% and 30%, respectively. Among 46 total deaths, 27 were from disease progression and 19 were from NRM primarily related to GVHD. The patients in remission at transplant showed better overall survival than those who were not in remission (85 % vs 34 % at 5 years post-transplant, respectively, P<0.05). The 5-year overall survival was 85 % for those in remission at transplant and 34 % for the remaining patients (P<0.05). Multivariate analyses showed that age older than 52 years and non-CR status at transplant were associated with an increased risk for mortality after RIST. Conclusions: Our study showed that RIST with this Flu/Bu8 regimen is feasible with durable engraftment and low early mortality. The clinical response rate is adequate for those who stayed in remission at transplantation, but otherwise a novel approach to prevent disease progression should be developed.

Introduction: Allogeneic hematopoietic stem cell transplantation (HCT) is a potentially curative treatment for several malignant and non-malignant hematological diseases. However, sometimes it is challenging to find human leukocyte antigen (HLA)-matched related or unrelated donors, especially in minority populations such as Hispanics. Transplantation of T cell replete HLA haploidentical graft (HaploHCT) followed by a high dose post-transplantation cyclophosphamide (PTCy) to eradicate alloreactive T cells is an option for populations with low donor availability. HaploHCT has emerged as an effective and safe strategy in this population (Luznik L et al. BBMT 2008), but data in Hispanics is scarce. Objective: The aim of our study was to describe the clinical characteristics and assess overall survival at 100 days, 1- and 3-years of patients who underwent haploHCT in two Colombian reference centers. Methods: An observational retrospective study was conducted at two tertiary referral centers in Colombia. Patients who underwent haploHCT at Clinica FOSCAL and Centro Medico Imbanaco between January 2013 and January 2020 were selected. Demographic and clinical characteristics where analyzed using descriptive statistics. The Kaplan-Meier method was used to assess overall survival (OS) rates and the log-rank test was used to compare survival rates between groups. All data were analyzed using R statistical software®. Results: Seventy-six patients were included. Mean age at transplantation was 34 years (range 18-60). Forty-two (57.89%) patients were female. Average body mass index was 19.86kg/m2. The majority of patients (57%) had a pre-transplantation ECOG performance status of 2. The most common indication for haploHCT was acute lymphoblastic leukemia (55.26%), followed by acute myeloid leukemia (23.64%). A sibling was the donor in 69.74% of the cases. Forty-seven (61.84%) patients were ABO-matched group. Peripheral blood stem cells were the graft source in 96% of the patients. The average number of infused CD34+ cells was 11.15 x 106/kg. Fludarabine-melphalan was the most commonly used conditioning regimen (57%), followed by fludarabine-busulfan-thiotepa (39%). Graft-versus-host disease (GVHD) prophylaxis consisted of PTCy (50 mg/kg/day) on days 3 and 4 after HCT and a calcineurin inhibitor plus mycophenolate mofetil from day 5 to day 35 post-HCT. Median time to neutrophil engraftment (neutrophils &gt; 0,5x109/L) was 15 days (range 10-33), while platelet engraftment, defined as as the second day of unsupported platelet count of ≥20 × 109, occurred at a median time of 13 days (range 5-38) post-transplantation. On day 28 post-HSCT, 93.4% of the patients had achieved 100% chimerism. OS was 91% (95%CI 84-97.5) at 100 days, 81% (95%CI 72-90) at 1-year, and 77% (95%CI 68-88) at 3-years after HaploHCT. C onclusion: The results of our haploHCT retrospective study in a Hispanic population are comparable to several other cohorts that have reported similar outcomes of haploHCT compared to HLA-matched HCT. The OS rates reported in our study suggest that haploHCT is a viable option in patients without an HLA-matched related or unrelated donor available, especially in populations with lower rates of suitable donors.

Purpose Transformed mycosis fungoides (MF) and Sézary syndrome (SS) are currently incurable. We studied the safety and efficacy of total skin electron beam with allogeneic hematopoietic stem-cell transplantation (HSCT) in patients with cutaneous T-cell lymphoma (CTCL). Patients and Methods Nineteen patients with advanced CTCL (median age, 50 years; four prior therapies) underwent total skin electron beam radiation followed by allogeneic HSCT between July 2001 and July 2008. Sixteen patients were conditioned with fludarabine (125 mg/m2) and melphalan (140 mg/m2) plus thymoglobulin (for mismatched donors). Graft-versus-host disease (GVHD) prophylaxis was with tacrolimus/mini methotrexate. Results Eighteen patients experienced engraftment, and one died as a result of sepsis on day 16. Median time to recovery of absolute neutrophil count (ANC) was 12 days. Fifteen achieved full donor chimerism, 12 had acute GVHD, and 12 were treated for chronic GVHD. The overall intent-to-treat response was 68%, and the complete response rate was 58%. Four of six patients died in complete remission as a result of bacterial sepsis (n = 2), chronic GVHD and fungal infection (n = 1), or lung cancer (n = 1); only two died as a result of progressive disease. Eight experienced relapse in skin; five regained complete response with reduced immunosuppression or donor lymphocyte infusions. Eleven of 13 are currently in complete remissions, with median follow-up of 19 months (range, 1.3 to 8.3 years). Median overall survival has not been reached. Conclusion Total skin electron beam followed by allogeneic stem-cell transplantation merits additional evaluation for a selected group of patients with refractory, advanced, cutaneous T-cell lymphoma with evidence for graft-versus-tumor effect.
