Predicting Severity of Radiation Induced Lymphopenia in Individual Proton Therapy Patients for Varying Dose Rate and Fractionation Using Dynamic 4-Dimensional Blood Flow Simulations. Int J Radiat Oncol Biol Phys 2023; 116:1226-1233. [PMID: 36739919 PMCID: PMC10363211 DOI: 10.1016/j.ijrobp.2023.01.054] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Revised: 01/11/2023] [Accepted: 01/27/2023] [Indexed: 02/05/2023]
Abstract
PURPOSE Radiation-induced lymphopenia has gained attention recently as the result of its correlation with survival in a range of indications, particularly when combining radiation therapy (RT) with immunotherapy. The purpose of this study is to use a dynamic blood circulation model combined with observed lymphocyte depletion in patients to derive the in vivo radiosensitivity of circulating lymphocytes and study the effect of RT delivery parameters. METHODS AND MATERIALS We assembled a cohort of 17 patients with hepatocellular carcinoma treated with proton RT alone in 15 fractions (fx) using conventional dose rates (beam-on time [BOT], 120 seconds) for whom weekly absolute lymphocyte counts (ALCs) during RT and follow-up were available. We used HEDOS, a time-dependent, whole-body, blood flow computational framework, in combination with explicit liver blood flow modeling, to calculate the dose volume histograms for circulating lymphocytes for changing BOTs (1 second-300 seconds) and fractionations (5 fx, 15 fx). From this, we used the linear cell survival model and an exponential model to determine patient-specific lymphocyte radiation sensitivity, α, and recovery, σ, respectively. RESULTS The in vivo-derived patient-specific α had a median of 0.65 Gy-1 (range, 0.30-1.38). Decreasing BOT to 1 second led to an increased average end-of-treatment ALC of 27.5%, increasing to 60.3% when combined with the 5-fx regimen. Decreasing to 5 fx at the conventional dose rate led to an increase of 17.0% on average. The benefit of both increasing dose rate and reducing the number of fractions was patient specificࣧpatients with highly sensitive lymphocytes benefited most from decreasing BOT, whereas patients with slow lymphocyte recovery benefited most from the shorter fractionation regimen. CONCLUSIONS We observed that increasing dose rate at the same fractionation reduced ALC depletion more significantly than reducing the number of fractions. High-dose-rates led to an increased sparing of lymphocytes when shortening the fractionation regimen, particularly for patients with radiosensitive lymphocytes at elevated risk.

Prognostic impact of the simple L-index and absolute lymphocyte count early after allogeneic hematopoietic stem cell transplantation. Cytotherapy 2023; 25:415-422. [PMID: 36599773 DOI: 10.1016/j.jcyt.2022.11.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Revised: 11/05/2022] [Accepted: 11/22/2022] [Indexed: 01/04/2023]
Abstract
BACKGROUND AIMS The L-index, designed as a quantitative parameter to simultaneously assess the duration and severity of lymphopenia, and absolute lymphocyte count (ALC) have a prognostic impact after allogeneic hematopoietic stem cell transplantation (allo-HSCT). However, discrepancies have been reported in the impact of ALC, and limited information is currently available on the L-index. METHODS To search for a better clinical tool, the authors retrospectively compared the simple L-index at 30 days (sL-index(30)), which aims to make the original L-index more compact, and ALC at 30 days (ALC(30)) after allo-HSCT in 217 patients who underwent allo-HSCT at the authors' institutions. RESULTS Median sL-index(30) was 11 712 (range, 4419-18 511) and median ALC(30) was 404 (range, 0-3754). In a multivariate analysis, higher sL-index(30) was associated with a significantly higher cumulative incidence of relapse (CIR) (hazard ratio [HR], 1.01, 95% confidence interval [CI], 1.00-1.02, P = 0.02 for every increase of 100 in sL-index(30)) as well as non-relapse mortality (NRM) (HR, 1.02, 95% CI, 1.00-1.03, P = 0.01 for every increase of 100 in sL-index(30)). Although higher ALC(30) was associated with significantly lower CIR (HR, 0.94, 95% CI, 0.89-1.00, P = 0.04 for every increase of 100/μL in ALC(30)), it was not extracted as an independent risk factor for NRM (HR, 0.96, 95% CI, 0.88-1.05, P = 0.39). Higher sL-index(30) was associated with a slightly higher rate of grade 3-4 acute graft-versus-host disease (GVHD) (HR, 1.02, 95% CI, 1.00-1.04, P = 0.12 for every increase of 100 in sL-index(30)) but not chronic GVHD (HR, 1.00, 95% CI, 0.99-1.01, P = 0.63). ALC(30) was not associated with rates of grade 3-4 acute GVHD (HR, 1.02, 95% CI, 0.88-1.17, P = 0.81) or chronic GVHD (HR, 1.02, 95% CI, 0.98-1.06, P = 0.34). In a receiver operating characteristic curve, the cutoff values of sL-index(30) and ALC(30) for CIR were 9000 and 500, respectively, and the cutoff value of sL-index(30) for NRM was 12 000. CONCLUSIONS sL-index(30) is a promising tool that may be applied to various survival outcomes. A large-scale prospective study is needed to clarify whether medical interventions based on sL-index(30) values will improve the clinical prognosis of patients.

Abstract
Numerous prognostic indexes have been developed in hematological diseases based on patient characteristics and genetic or molecular assessment. However, less attention was paid to more accessible parameters, such as neutrophils, lymphocytes, monocytes, and platelet counts. Although many studies have defined the role of neutrophil-to-lymphocyte or platelet-to-lymphocyte in lymphoid malignancies, few applications exist for myeloid neoplasm or hematopoietic stem cell transplantation procedures. In this review, we synthesized literature data on the prognostic value of count blood cells in myeloid malignancies and hematopoietic stem cell transplantation in the context of classical prognostic factors and clinical outcomes.

Early reconstitution of lymphocytes after allogenic hematopoietic stem cell transplantation affects chronic graft-versus-host disease. Pediatr Int 2022; 64:e15222. [PMID: 35790056 DOI: 10.1111/ped.15222] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2021] [Revised: 04/05/2022] [Accepted: 04/15/2022] [Indexed: 01/06/2023]
Abstract
BACKGROUND Lymphocyte reconstitution after hematopoietic stem cell transplantation (HSCT) is important for the prevention of infections, as well as for the reduction of recurrence, by its graft versus tumor effect. However, these lymphocytes may also play a role in the development of graft-versus-host disease (GVHD). Few studies have investigated the association between lymphocyte reconstitution and clinical outcomes after HSCT. METHODS This issue was investigated by retrospectively analyzing pediatric patients who received their first allogeneic-HSCT using a newly developed parameter, the LD-index, which evaluates both the intensity and duration of lymphopenia. A total of 101 patients underwent allo-HSCT from April 2007 to August 2019 in our hospital. Excluding patients who died before lymphocyte recovery or underwent multiple HSCT, 78 patients were analyzed for associations between the LD-index with various factors relating to HSCT. RESULTS A significantly high association was observed between a low LD-index and the incidence of chronic GVHD (P = 0.0019). Analysis of predictive factors for chronic GVHD was carried out using univariate analysis. Lower LD-index, donor source and duration of lymphopenia were found to be significant factors associated with chronic GVHD. Multivariate analysis, however, only identified an association between a lower LD-index and an increased incidence of chronic GVHD (P = 0.00081). CONCLUSIONS Early reconstitution of lymphocytes after allo-HSCT is associated with a higher incidence of chronic GVHD.

Abstract
Type 1 regulatory (Tr1) T cells induced by enforced expression of interleukin-10 (LV-10) are being developed as a novel treatment for chemotherapy-resistant myeloid leukemias. In vivo, LV-10 cells do not cause graft-versus-host disease while mediating graft-versus-leukemia effect against adult acute myeloid leukemia (AML). Since pediatric AML (pAML) and adult AML are different on a genetic and epigenetic level, we investigate herein whether LV-10 cells also efficiently kill pAML cells. We show that the majority of primary pAML are killed by LV-10 cells, with different levels of sensitivity to killing. Transcriptionally, pAML sensitive to LV-10 killing expressed a myeloid maturation signature. Overlaying the signatures of sensitive and resistant pAML onto the public NCI TARGET pAML dataset revealed that sensitive pAML clustered with M5 monocytic pAML and pAML with MLL rearrangement. Resistant pAML clustered with myelomonocytic leukemias and those bearing the core binding factor translocations inv(16) or t(8;21)(RUNX1- RUNX1T1). Furthermore, resistant pAML upregulated the membrane glycoprotein CD200, which binds to the inhibitory receptor CD200R1 on LV-10 cells. In order to examine if CD200 expression on target cells can impair LV-10 cell function, we overexpressed CD200 in myeloid leukemia cell lines ordinarily sensitive to LV-10 killing. Indeed, LV-10 cells degranulated less and killed fewer CD200-overexpressing cells compared to controls, indicating that pAML can utilize CD200 expression for immune evasion. Altogether, the majority of pAML are killed by LV-10 cells in vitro, supporting further LV-10 cell development as an innovative cell therapy for pAML.

Abstract
Background: Hematopoietic stem cell transplantation (HSCT) is the most effective of all hematologic malignancies treatments, resulting in a significant improvement in survival rate. Objectives: This study aimed at determining the survival rate and factors affecting the survival in patients undergoing hematopoietic stem cell transplantation, using the joint model. Methods: This study was a retrospective cohort study, used for collecting data from patients with hematopoietic malignancies who underwent hematopoietic stem cell transplantation in Taleghani Hospital (Shahid Beheshti University of Medical Sciences), Tehran, Iran during the years 2007 and 2015 and were followed up till 2017. A Bayesian joint model of longitudinal and survival was chosen, using Win Bugs software. Results: A total of 395 patients were enrolled. The median overall survival was 6.3 years (95% CI (5.86, 6.76)). Eighty-one patients had died. The obtained results from this study manifested that age (HR: 1.02, 95% CI: (1.002, 1.04)) and pre-transplantation relapse (HR = 1.64, 95% CI: (1.09, 2.4)) have incremental impact on death after transplantation, while malignancy type (NHL (HR: 0.33, 95%CI: (0.152, 0.73)) and AML (HR: 0.62, 95% CI: (0.29, 0.7)) are also effective in reducing death after transplantation. Similarly, the correlation index between longitudinal and survival models proved to be significant (HR: 0.6, 95% CI: (0.0802, 0.37)). Conclusions: This study showed that age, per-transplantation relapse, and malignancy type are the effective factors in the survival rate. Moreover, the link parameter between longitudinal response (WBC) and the survival indicated that an increase in WBC count leads to a decrease in the death risk.

Abstract
Lymphoid recovery following myeloablative stem cell transplantation (SCT) displays a logistic pattern of exponential growth followed by a plateau. Within this logistic framework, lymphoid recovery is characterized by the parameters R (slope of ascent), a (time of maximal rate of ascent) and K (plateau), the 'steady-state' lymphocyte count. A retrospective analysis of allogeneic SCT performed from 2008 to 2013 was undertaken to compare lymphoid recovery and clinical outcomes in 131 patients with acute myelogenous leukemia, acute lymphocytic leukemia, and myelodysplastic syndromes. Using Prism software, a logistic curve was successfully fit to the absolute lymphocyte count recovery in all patients. Patients were classified according to the magnitude and rate of lymphoid recovery; pattern A achieved an absolute lymphocyte counts (ALC) of >1000/μL by day 45, pattern B an ALC 500 < x < 1000/μL, and pattern C an ALC <500/μL. Pattern A was characterized by a higher mean K (p < .0001) compared with patterns B and C. Patients with patterns B and C were more likely to have mixed T cell chimerism at 90 d following SCT (p = .01). There was a trend towards improved survival (and relapse-free survival) in those with pattern A and B at 1 year compared to pattern C (p = .073). There was no difference in cGVHD (p = .42) or relapse (p = .45) between pattern types. Cytomegalovirus (CMV), aGVHD, and all relapse were heralded by deviation from logistic behavior. Pattern C patients were more likely to require donor lymphocyte infusion (DLI) (p = .017). Weaning of tacrolimus post-transplant was associated with a second, separate logistic expansion in some patients. This study demonstrated that lymphoid reconstitution follows a prototypical logistic recovery and that pattern observed correlates with T cell chimerism and need for DLI, and may influence survival.

Abstract
AIM To examine the optimal absolute lymphocyte count (ALC) cut-off utilizing receiver operator characteristics (ROC) in addition to graft characteristics associated with early ALC recovery.
METHODS Patients who received T-cell replete peripheral hematopoietic cell transplantation (HCT) for acute leukemia were identified. ALC cut-off was established using ROC analysis and subsequently the cohort was stratified. Time to endpoint analysis and cox regression modelling was computed to analyze outcomes.
RESULTS A total of 72 patients met the inclusion criteria and were analyzed. Optimal ALC cut-off was established to be on day 14 (D14) with ALC > 0.3 × 109/L. At 2 years, cumulative incidence of relapse was 16.9% vs 46.9% (P = 0.025) for early and delayed lymphocyte recovery cohorts, respectively. Chronic graft vs host disease was more prevalent in the early lymphocyte recovery (ELR) group at 70% vs 27%, respectively (P = 0.0006). On multivariable analysis for relapse, ELR retained its prognostic significance with HR = 0.27 (0.05-0.94, P = 0.038).
CONCLUSION ELR is an independent predictor for relapse in patients receiving allogeneic HCT for acute leukemia. ELR was influenced by graft characteristics particularly CD34 count.

Abstract
PURPOSE Patients with metastatic or relapsed pediatric sarcomas receive cytotoxic regimens that induce high remission rates associated with profound lymphocyte depletion, but ultimately few survive long term. We administered adjuvant immunotherapy to patients with metastatic and recurrent pediatric sarcomas in an effort to improve outcomes. EXPERIMENTAL DESIGN Mononuclear cells were collected via apheresis, and tumor lysate was acquired via percutaneous biopsy at enrollment. Participants received standard antineoplastic therapy, followed by autologous lymphocytes, tumor lysate/keyhole limpet hemocyanin-pulsed dendritic cell vaccinations ± recombinant human IL7. Primary outcomes were toxicity and vaccine responses. Secondary outcomes were immune reconstitution, event-free survival, and overall survival (OS). RESULTS Forty-three patients enrolled and 29 received immunotherapy. The regimen was well tolerated. Intent-to-treat analysis demonstrated 5-year OS of 51% with significant differences based upon histologic group (63% vs. 0% for Ewing/rhabdomyosarcoma vs. other sarcomas) and response to standard therapy (74% no residual disease vs. 0% residual disease). Five-year intent-to-treat OS of patients with newly diagnosed metastatic Ewing/rhabdomyosarcoma was 77%, higher than previously reported in this population and higher than observed in a similar group treated with an earlier adjuvant immunotherapy regimen (25% 5-year OS). T-cell responses to autologous tumor lysate were identified in 62% of immunotherapy recipients, and survival was higher in those patients (73% 5-year OS with vs. 37% without immune response, P = 0.017). Immune reconstitution, measured by CD4 count recovery, was significantly enhanced in subjects treated with recombinant human IL7. CONCLUSIONS Adjuvant immunotherapy may improve survival in patients with metastatic pediatric sarcoma. Clin Cancer Res; 22(13); 3182-91. ©2016 AACR.

Risk factors for cytomegalovirus DNAemia following haploidentical stem cell transplantation and its association with host hepatitis B virus serostatus. J Clin Virol 2015; 75:10-5. [PMID: 26735213 DOI: 10.1016/j.jcv.2015.12.003] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2015] [Revised: 11/10/2015] [Accepted: 12/10/2015] [Indexed: 12/24/2022]
Abstract
BACKGROUND The risk factors associated with CMV DNAemia are not well known after haploidentical stem cell transplantation (SCT). OBJECTIVES This study investigated the risk factors and prognosis for CMV DNAemia among CMV seromatched donors and recipients (D+/R+). STUDY DESIGN A retrospective study of patients undergoing haploidentical stem cell transplantation (SCT) between January 2010 and January 2012 was conducted. Cox regression analysis was performed to identify the risk factors for CMV DNAemia. These possible factors included recipient/donor age, recipient/donor gender, gender disparity, recipient HBsAg serostatus, diagnosis, risk stratification, anti-thymocyte globulin (ATG) dose (6mg/kg,10mg/kg), early neutrophil engraftment (≤12 days, >12 days), absolute lymphocyte count on day 30 (ALC30) and the occurrence of acute GVHD before CMV DNAemia. RESULTS The total number of patients was 248 with median age of 31 years (range, 14-56). The cumulative incidence of CMV DNAemia (146/248) was 59.5%. CMV DNAemia was first detected after a median of +35 days (range,12-82). Seventeen patients (17/146, 11.6%) developed CMV disease. Multivariate analysis identified HBsAg seropositivity (P=0.002, hazard ratio (HR)=1.833; 95%CI=1.257-2.673) and the occurrence of acute GVHD before CMV DNAemia (P=0.014; HR=1.520; 95%CI=1.088-2.124) as risk factors for CMV DNAemia. CMV DNAemia was associated with subsequent II-IV acute graft-versus-host disease (GVHD) (P=0.014), III-IV aGVHD (P=0.013) and chronic GVHD (P=0.008). Totally, CMV DNAemia was found to be a poor prognostic factor in terms of non-relapse mortality (NRM) (P=0.003, HR=2.730; 95%CI=1.406-5.197), and overall survival (OS) (P=0.045, HR=1.654; 95%CI=1.012-2.701). CONCLUSIONS Our data showed HBsAg seropositivity was associated with an increased risk of cytomegalovirus DNAemia. Detection of CMV DNAemia proved to be a poor prognostic factor for haploidentical patients.

Optimal Threshold and Time of Absolute Lymphocyte Count Assessment for Outcome Prediction after Bone Marrow Transplantation. Biol Blood Marrow Transplant 2015; 22:505-13.

Abstract
The recovery pace of absolute lymphocyte count (ALC) is prognostic after hematopoietic stem cell transplantation. Previous studies have evaluated a wide range of ALC cutoffs and time points for predicting outcomes. We aimed to determine the optimal ALC value for outcome prediction after bone marrow transplantation (BMT). A total of 518 patients who underwent BMT for acute leukemia or myelodysplastic syndrome between 1999 and 2010 were divided into a training set and a test set to assess the prognostic value of ALC on days 30, 60, 90, 120, 180, as well as the first post-transplantation day of an ALC of 100, 200, 300, 400, 500, and 1000/μL. In the training set, the best predictor of overall survival (OS), relapse-free survival (RFS), and nonrelapse mortality (NRM) was ALC on day 60. In the entire patient cohort, multivariable analyses demonstrated significantly better OS, RFS, and NRM and lower incidence of graft-versus-host disease (GVHD) in patients with an ALC >300/μL on day 60 post-BMT, both including and excluding patients who developed GVHD before day 60. Among the patient-, disease-, and transplant-related factors assessed, only busulfan-based conditioning was significantly associated with higher ALC values on day 60 in both cohorts. The optimal ALC cutoff for predicting outcomes after BMT is 300/μL on day 60 post-transplantation.

Abstract
INTRODUCTION Early lymphocyte recovery after allogeneic hematopoietic stem cell transplantation (HSCT) is related to the prevention of serious infections and the clearing of residual tumor cells. METHODS We analyzed the absolute lymphocyte count at 20 (D+20) and 30 (D+30) days after HSCT in 100 patients with malignant hematologic diseases and correlated with the risk of transplant-related mortality, overall survival (OS), disease-free survival (DFS), nonrelapsed mortality (NRM), and risk of infection. RESULTS Patients presenting with lymphocyte counts of <300 × 103/μL on D+30 have a 3.76 times greater risk of death in <100 days. Over a medium follow-up of 20 months OS, DFS, and NRM were similar between the groups. CONCLUSION In our group of patients delayed lymphocyte recovery after HSCT was a predictor of early death post-HSCT.

Abstract
PURPOSE Quantitative relationships between 9-β-D-arabinofuranosyl-2-fluoroadenine (F-ara-A) concentrations and lymphosuppression have not been reported, but would be useful for regimen design. A population pharmacokinetic/pharmacodynamic model was constructed in this study using data from 41 hematopoietic cell transplant (HCT) recipients conditioned with busulfan in combination with fludarabine (total dose 120 mg/m², Protocol 1519) or with fludarabine (total dose 250 mg/m²) with rabbit antithymocyte globulin (rATG, Protocol 2041). METHODS Individual pharmacokinetic parameters were fixed to post hoc Bayesian estimates, and circulating absolute lymphocyte counts (ALC) were obtained during the 3 weeks prior to graft infusion. A semi-physiological cell-kill model with three lymphocyte transit compartments was applied and aptly characterized the time course of suppression of circulating ALC by fludarabine administration. Drug- and system-specific parameters were estimated using a maximum likelihood expectation maximization algorithm, and the final model was qualified using an internal visual predictive check. RESULTS The final model successfully characterized the time course and variability in ALC. Pharmacodynamic parameters exhibited considerable between subject variability (38.9-211 %). The HCT protocol was the only covariate associated with the pharmacodynamic parameters, specifically the lymphocyte kill rate, the transit rate between lymphocyte compartments, and the baseline ALC. CONCLUSIONS This model can be used to simulate the degree of lymphosuppression for design of future fludarabine-based conditioning regimens.

Abstract
Background Despite advances in the treatment of acute leukemia, many patients need to undergo
hematopoietic stem cell transplantation. Recent studies show that early lymphocyte
recovery may be a predictor of relapse and survival in these patients. Objective To analyze the influence of lymphocyte recovery on Days +30 and +100
post-transplant on the occurrence of relapse and survival. Methods A descriptive, retrospective study was performed of 137 under 21-year-old
patients who we resubmitted to hematopoietic stem cell transplantation for acute
leukemia between 1995 and 2008. A lymphocyte count < 0.3 x 109/L
on Day +30 post-transplant was considered to be inadequate lymphocyte recovery and
counts ≥ 0.3 x 109/L were considered adequate. Lymphocyte
recovery was also analyzed on Day +100 with < 0.75 x 109/Land
≤ 0.75 x 109/L being considered inadequate and adequate
lymphocyte recovery, respectively. Results There was no significant difference in the occurrence of relapse between patients
with inadequate and adequate lymphocyte recovery on Day +30 post-transplant.
However, the transplant-related mortality was significantly higher in patients
with inadequate recovery on Day +30. Patients with inadequate lymphocyte recovery
on Day +30 had worse overall survival and relapse-free survival than patients with
adequate recovery. There was no significant difference in the occurrence of
infections and acute or chronic graft-versus-host disease. Patients with
inadequate lymphocyte recovery on Day +100 had worse overall survival and
relapse-free survival and a higher cumulative incidence of relapse. Conclusion The evaluation of lymphocyte recovery on Day +30 is not a good predictor of
relapse after transplant however patients with inadequate lymphocyte recovery had
worse overall survival and relapse-free survival. Inadequate lymphocyte recovery
on Day +100 is correlated with higher cumulative relapse as well as lower overall
survival and relapse-free survival.

Abstract
We have recently shown that lymphocyte and monocyte recovery by day +100 are associated with survival post myeloablative allogeneic hematopoietic transplant for acute leukemia. We hypothesized that lymphocyte and monocyte recovery would have a similar impact on survival in the reduced intensity setting. To test this hypothesis, we analyzed clinical data from 118 consecutive fludarabine/melphalan-conditioned patients by correlating peripheral blood absolute lymphocyte counts and monocyte counts (ALC and AMC, respectively) at days +15, +30, +60 and +100 with the outcomes. Multivariate analysis revealed that day +100 AMC (risk ratio (RR) 0.22, 95% confidence interval (CI) 0.07-0.73, P=0.01) and mild chronic GVHD (RR 0.09, 95% CI 0.005-0.43, P=0.008) were independently associated with survival. To explore whether the patterns of lymphocyte and monocyte recovery had a prognostic value, we performed unsupervised hierarchical clustering on the studied hematopoietic parameters and identified three patient clusters, A-C. Patient clusters A and B both had improved OS compared with cluster C (77.8 months vs not reached vs 22.3 months, respectively, P<0.001). No patient in cluster C had a day +100 AMC >300. Both severe acute GVHD and relapse occurred more frequently in cluster C. Our data suggest that patients with low AMC by day +100 post fludarabine/melphalan-conditioned allogeneic hematopoietic SCT may be at risk for poor outcomes.

Abstract
Natural killer (NK) cells differentiated from hematopoietic stem cells (HSCs) may have significant clinical benefits over NK cells from adult donors, including the ability to choose alloreactive donors and potentially more robust in vivo expansion. Stromal-based methods have been used to study the differentiation of NK cells from HSCs. Stroma and cytokines support NK cell differentiation, but may face considerable regulatory hurdles. A recently reported clinical-grade, heparin-based method could serve as an alternative. How the stromal-based and heparin-based approaches compare in terms of NK cell generating efficiency or function is unknown. We show that compared with heparin-based cultures, stroma significantly increases the yield of HSC-derived NK cells by differentiating less-committed progenitors into the NK lineage. NK cells generated by both approaches were similar for most NK-activating and -inhibiting receptors. Although both approaches resulted in a phenotype consistent with CD56(bright) stage IV NK cells, heparin-based cultures favored the development of CD56(+)CD16(+) cells, whereas stroma produced more NK cell immunoglobulin-like receptor-expressing NK cells, both of which are markers of terminal maturation. At day 21, stromal-based cultures demonstrated significantly more IL-22 production, and both methods yielded similar amounts of IFN-γ production and cytotoxicity by day 35. These findings suggest that heparin-based cultures are an effective replacement for stroma and may facilitate clinical trials testing HSC-derived NK cells.

Abstract
Many previous studies of immune reconstitution (IR) postallogeneic hematopoietic stem cell transplantation (HSCT) have focused on lymphocyte recovery. Recognizing that IR involves complex interactions between innate and adaptive immune networks, we hypothesized that patterns of both monocyte and lymphocyte recovery could provide additional prognostic information. To test our hypothesis, we analyzed data from 135 consecutive patients undergoing myeloablative allogeneic HSCT for acute myeloid (AML) and lymphoblastic leukemia (ALL) from 2001 to 2010. The absolute lymphocyte and monocyte counts (ALC and AMC, respectively) were determined longitudinally at days +15, +30, +60, and +100, and correlated with clinical outcomes. At the day +30 time point, both ALC and AMC >0.3 × 10(9) cells/L were strongly associated with improved survival (overall survival [OS] 29.6 months versus 5.4 months, P = .006 and 25.3 months versus 5.1 months, P = .01 respectively), a pattern that generally continued through the day +100 evaluation. Multivariate analysis revealed the following independent prognostic factors: early disease status at transplantation, the development of chronic GVHD, the day +30 AMC, day +100 AMC, and day +100 ALC. To further explore whether any inherent patterns in the timing of lymphocyte and monocyte recovery had prognostic value post-HSCT, we performed unsupervised hierarchical clustering on the longitudinal hematopoietic parameters studied in this cohort. Four clusters of patients were identified: clusters A-D. Patient clusters B and D both demonstrated improved ALC and AMC recovery at the day +60 and day +100 time points and had significantly improved OS compared with clusters A and C (57.8 months versus 19.7 and 4.4 months, respectively, P < .001). Our data suggest that patients with poor lymphocyte and monocyte recovery beyond the day +60 time points may be at risk for poorer outcomes, and that further investigation into lymphoid/myeloid interactions in developing individualized immunotherapy is warranted.

Abstract
Rapid recovery of lymphocytes after T-cell depleted hematopoietic SCT (HSCT) protects from relapse of myeloid malignancies. Whether lymphocyte reconstitution has a similar role after non-manipulated transplantation is controversial. We assessed numbers of CD4 and CD8 T-cells, natural killer (NK) cells and B-cells, before and 1, 3, 6, 12 and 24 months after T-cell replete transplantation in 345 patients. Lymphocyte subset counts up to 6 months post transplant had no effect on relapse. Elevated number of NK cells 12 months post transplant protected from relapse. As a novel finding, early recovery of NK cells was associated with significant protection from TRM already at the 3 and 6 months time points (P=0.03, P=0.02). In Cox multivariable models, patients with NK cells above 150/μL were significantly protected from TRM (hazard ratio (HR) 0.45, 95% confidence interval (95% CI) 0.21-0.95, P=0.03), an effect comparable in magnitude with that of carrying >200 CD4 T-cells/μL (HR 0.37, 95% CI 0.19-0.74, P=0.005). CD8 T-cell and B-cell recovery did not affect the rates of relapse or TRM. Early reconstitution of NK cells and CD4 T-cells in patients undergoing T-cell replete HSCT independently protected from TRM. Only a weak protection from disease relapse was noted for patients with high numbers of NK cells, and this occurred only late after transplantation.

Abstract
Rapid lymphocyte recovery after bone marrow or peripheral blood transplantation is associated with improved survival. However, the impact of early lymphocyte recovery has not been examined after umbilical cord blood transplant (UCBT). We evaluated lymphocyte recovery in 360 consecutive patients with hematologic malignancy that underwent UCBT between 2001 and 2007. Uniform myeloablative (MA), reduced intensity conditioning (RIC) and graft-versus-host disease prophylaxis regimens were used. In multivariate analysis, an absolute leukocyte count (ALC) >200 × 10(6)/L at day 30 (n = 73) after MA conditioning was associated with superior 2-year overall survival (OS) (73% versus 61%; P = .02) (relative risk [RR]: 2.29; 95% confidence interval [CI]: 1.15-4.56), progression-free survival (PFS) (68% versus 54%; P = .05) (RR: 1.96; 95% CI: 0.99-3.86) and less transplant-related mortality (8% versus 28%, P < .01) (RR: 4.38; 95% CI: 1.65-11.60) compared to ≤200 × 10(6)/L (n = 43). Similarly, an ALC >200 × 10(6)/L at day 42 (n = 105) after RIC was associated with superior 2-year OS (59% versus 41%, P < .01) (RR: 2.10; 95% CI: 1.3-3.41) and PFS (46% versus 36%, P = .05) (RR: 1.58; 95% CI: 1.01-2.49) compared to ≤200 × 10(6)/L (n = 55). There was no significant relationship between ALC and relapse. Rapid lymphocyte recovery early after UCBT predicts better survival in patients with hematologic malignancies.

Abstract
Stem cell transplantation (SCT) from a healthy donor can be curative for patients with hematologic malignancies resistant to other treatments. Elimination of malignant cells through a graft-versus-leukemia (GVL) effect involves donor T and natural killer (NK) cells, but their relative contribution to this process is poorly defined. NK cell alloreactivity and GVL effects are controlled by the nature of the interaction of NK activation receptors and killer-immunoglobulin-like-receptors (KIR) with major histocompatibility locus class I antigens on the target cell. We performed KIR-genotyping of HLA-identical sibling donors in 246 T cell-depleted SCTs to identify genetic factors affecting transplant outcome (treatment-related mortality [TRM], leukemic relapse, and survival). Univariate and multivariate analysis of transplant-related risk factors and KIR genotyping was performed to identify independent variables predictive of outcome for different forms of leukemia. Further to confirming known predictive factors for TRM and survival (CD34 cell dose, patient age, disease stage), statistical analysis revealed that 3 donor B haplotype KIR genes, 2DL5A, 2DS1, and 3DS1, were associated with significantly less relapse in patients with acute myelogenous leukemia (AML) (13% versus 57%) but not in patients with other myelogenous or lymphoid malignancies. AML patients receiving SCT from donors with these KIR genes relapsed 4 times less frequently than patients transplanted from donors with other KIR genotypes. These findings suggest specific, genetically determined, interactions between NK cells and AML cells that facilitate the GVL effect, and have implications for donor selection for AML patients.

Abstract
Unmanipulated human leukocyte antigen (HLA)-mismatched/haploidentical blood and marrow transplantation is an established treatment for patients without HLA-matched related or unrelated donors. However, the prognostic significance of early lymphocyte recovery in this transplant setting is not defined. In this study, we investigated the association of day 30 absolute lymphocyte count (ALC-30) with outcome after unmanipulated HLA-mismatched/haploidentical transplantation. We prospectively analyzed the relationship between ALC-30 and transplant outcomes in 206 patients with hematologic malignancies receiving T-cell-replete transplantation from HLA-mismatched/haploidentical related donors. Multivariate analysis showed that ALC-30 above the cutoff value of 300 cells/microL was associated with improved overall survival (hazard ratio [HR], 0.258; 95% confidence interval [CI], 0.141-0.472; p < 0.0001); improved cancer-free survival (HR, 0.289; 95% CI, 0.166-0.501; p < 0.0001); reduced relapse (HR, 0.370; 95% CI, 0.161-0.853; p = 0.020); and decreased transplant-related mortality (HR, 0.211; 95% CI, 0.097-0.457; p < 0.0001). Our results suggest that the recovery of ALC-30 might have an influence on transplant outcomes following unmanipulated HLA-mismatched/haploidentical transplantation.

Abstract
This study investigated the impact of pretransplant cytomegalovirus (CMV) serostatus and posttransplant CMV reactivation and disease on umbilical cord blood transplant (UCBT) outcomes. Between 1994 and 2007, 332 patients with hematologic malignancies underwent UCBT and 54% were CMV seropositive. Pretransplant recipient CMV serostatus had no impact on acute or chronic graft-versus-host disease (aGVHD, cGVHD), relapse, disease-free survival (DFS), or overall survival (OS). There was a trend toward greater day 100 treatment-related mortality (TRM) in CMV-seropositive recipients (P=.07). CMV reactivation occurred in 51% (92/180) of patients with no difference in myeloablative (MA) versus reduced-intensity conditioning (RIC) recipients (P=.33). Similarly, reactivation was not influenced by the number of UCB units transplanted, the degree of HLA disparity, the CD34(+) or CD3(+) cell dose, or donor killer cell immunoglobulin-like receptor (KIR) gene haplotype. Rapid lymphocyte recovery was associated with CMV reactivation (P=.02). CMV reactivation was not associated with aGVHD (P=.97) or cGVHD (P=.65), nor did it impact TRM (P=.88), relapse (P=.62), or survival (P=.78). CMV disease occurred in 13.8% of the CMV-seropositive patients, resulting in higher TRM (P=.01) and lower OS (P=.02). Thus, although recipient CMV serostatus and CMV reactivation have little demonstrable impact on UCB transplant outcomes, the development of CMV disease remains a risk, associated with inferior outcomes.

Abstract
A higher absolute lymphocyte count 1 month (LC30) after allogeneic hematopoietic stem cell transplantation (HSCT) is associated with better outcome in patients transplanted from a matched sibling. We studied 102 SCT patients with unrelated donor and matched unrelated donors and the relationship between LC30 and outcome in patients with myelogenous leukemia. Conditioning was myeloablative using cyclophosphamide (Cy) with busulfan (Bu; n=61) or total body irradiation (TBI; n=41). LC30 was low (<0.2x10(9)/L) in 18 patients, intermediate (0.2-1.0x10(9)L) in 67, and high (>1.0x10(9)/L) in 17 patients. In multivariate analysis, independent factors associated with high relapse-free survival (RFS) were high LC30, high CD34 cell-dose, and absence of acute graft-versus-host disease (aGVHD) grades II-IV. When analyzed as a continuous variable in multivariate analysis, a higher LC30 was associated with a lower transplant-related mortality (TRM; relative hazard [RH]=0.87, P < .05), higher relapse-free survival (RH=3.42, P=.036), and improved survival (RH=4.53, P=.016, excluding GVHD). In patients with high, intermediate, and low LC30, overall survival (OS) was 91% versus 60%, versus 36% (P=.02 and .001, respectively). This significant relationship was maintained in patients who did not develop GVHD by day 30. Significant risk factors to develop low LC30 was chronic myelogenous leukemia (CML; hazard ratio [HR] 0.73, P=.001), prophylaxis with granulocyte colony-stimulating factor (G-CSF; HR 0.81, P=.02) and aGVHD (HR 0.84, P=.05). These results indicate that LC30 is an independent prognostic factor for transplant outcome in matched unrelated SCT for myelogenous malignancies.

Abstract
Lymphocyte and platelet recovery may influence outcomes of allo-SCT for treatment of AML. It is not clear, however, if this impact is independent of patient and transplant characteristics. To investigate this question, we evaluated the influence of pre- or post transplant factors on day +30 absolute lymphocyte count (ALC) and the speed of platelet engraftment. We studied 106 AML patients treated with fludarabine and melphalan reduced-intensity conditioning and allo-SCT. Twenty nine percent of patients were in CR at the initiation of the conditioning, 39% had active disease with circulating blasts and 32% had active disease without circulating blasts. The graft source was peripheral blood from a matched sibling donor in 55% and BM from a matched unrelated donor in 45%. Our data showed that the presence of circulating blasts before transplantation is significantly correlated with low post-SCT day +30 ALC and slow platelet engraftment. This finding suggests that the impact of early ALC and platelet recovery on transplant outcome may not be independent of disease status at transplantation.

Abstract
An infection after allogeneic stem cell transplantation (SCT) can affect the activity of immune cells and increase the level of proinflammatory cytokines. Further, a post-SCT infection may influence the milieu of the graft-versus-leukemia (GVL) effect and graft-versus-host disease (GVHD). We performed a retrospective study of patients with acute leukemia who had undergone allogeneic SCT using the same preparative regimens and bone marrow as the stem cell source to determine if early post-transplant infection was associated with the risk of leukemic relapse and GVHD. The analysis revealed that patients who had a febrile infection (FI) before post-transplant day 21 (FI group) had a lower actuarial probability of leukemic relapse (P < 0.001) and a higher relapse-free survival rate (P = 0.012) than those patients who did not have a FI before post-transplant day 21 (non-FI group). The experience of early post-transplant FI (HR = 0.316; 95% CI = 0.174-0.575; P < 0.001), together with the presence of chronic GVHD and high risk cytogenetics, were independent predictive factors for post-transplant leukemic relapse. The FI group had a trend towards a higher lymphocyte count on post-transplant day 21 than the non-FI group (P = 0.063), despite the delayed recovery of the platelet count and a trend towards delayed recovery of the neutrophil count. These findings suggest that a change in the immunologic network by infectious diseases in the early post-transplant period favors the milieu of the GVL effect. The specific immunologic change during FI, which can potentiate the GVL effect, remains to be determined.

Abstract
To study the effect of early lymphocyte recovery post-allogeneic hematopoietic stem cell transplantation (HSCT) on outcome in pediatric ALL, we reviewed 136 consecutive pediatric patients with ALL who received allogeneic HSCT between 1994 and 2005 at the Hospital for Sick Children, Toronto, Canada. Patients with an absolute lymphocyte count (ALC) <0.3 x 10(9) per liter at day 21 (n=104) had more than five times risk of relapse compared to those with ALC >0.3 x 10(9) per liter (n=32) (hazard ratio (HR) 5.3; P=0.002) and had inferior 3-year event-free survival, (EFS), 0.42 (95% confidence interval (CI) 0.32, 0.51) compared to 0.66 (95% CI 0.48, 0.82; P=0.02). Similarly, patients with an ALC <0.3 x 10(9) per liter (n=48) at day 30 were more than twice as likely to relapse compared to those with an ALC >0.3 x 10(9) per liter (n=88) (HR 2.2; P=0.01) and had an inferior 3-year EFS, 0.30 (95% CI 0.18, 0.45) compared to 0.57 (95% CI 0.46, 0.68; P=0.0001). Interestingly, increasing ALC at days 21 and 30 was not associated with increased incidence of acute or chronic GVHD or transplant-related mortality (TRM). Early lymphocyte recovery post-HSCT is associated with a significant GVL without increase in GVHD.

Abstract
Several studies have shown that a higher lymphocyte count 3-4 weeks after allogeneic stem cell transplantation (SCT) is associated with better transplant outcome. However, the factors determining early lymphocyte recovery are not defined. To further explore the relationship between lymphocyte recovery and outcome we analyzed lymphocyte counts and other engraftment parameters in 157 patients with leukemia (48 acute myelogenous leukemia, 80 chronic myelogenous leukemia, and 29 acute lymphoblastic leukemia [ALL]) receiving T cell-depleted myeloablative SCT from an HLA-identical sibling. In multivariate analysis the day 30 absolute lymphocyte count (LC30) above the median of 450/muL was associated with improved survival (71% +/- 5% versus 38% +/- 6%, P < .0001), less relapse (21% +/- 5% versus 44% +/- 7%, P = .009), less nonrelapse mortality (NRM; 9 +/- 3 versus 36% +/- 6%, P < .0001) and less acute graft-versus-host disease (aGVHD) (34% +/- 5% versus 51% +/- 6%, P = .025). The beneficial effect of a higher LC30 influenced outcome in patients with both standard and high-risk disease but did not affect survival and relapse in ALL. We found that a higher LC30 correlated with higher lymphocyte counts at all time points between 30 and 90 days post-SCT and also with more rapid neutrophil and platelet engraftment. These results indicate that LC30 is a surrogate for robust engraftment and identifies an "at-risk" population of patients after T cell-depleted SCT.

Abstract
The effect of the transplant dose of each cell subset on engraftment kinetics and transplantation outcomes was evaluated in HLA-identical allogeneic peripheral blood stem cell transplantation (PBSCT). Sixty-nine patients were included in this retrospective study. Engraftment kinetics, transplantation outcomes, and immune reconstitution up to 1 year after transplantation were analyzed according to the transplant dose of CD34+ and non-CD34+ cells, including natural killer (NK) cells and CD8+ cytotoxic T (Tc) cells. An accelerated neutrophil engraftment was strongly associated with a higher transplant dose of NK cells (12 versus 16 days, P < .001) and Tc cells (13 versus 16 days, P < .001) but not CD34+ cells (P = .442). Survival analyses revealed a favorable prognosis for patients who received a higher dose of non-CD34+ cell subsets, rather than CD34+ cells, in terms of overall survival (OS; P = .024 for NK cells and .050 for Tc cells) and nonrelapse mortality (NRM; P = .005 for NK cells, .060 for Tc cells). In addition, a higher transplant dose of NK and Tc cells was correlated with a faster lymphoid reconstitution. In multivariate analyses, rapid neutrophil engraftment was correlated with a higher transplant dose of NK cells (P = .001) and Tc cells (P = .004). Moreover, an increased OS was associated with the NK cell dose (P = .007) and chronic graft-versus-host disease (P = .009), whereas a decreased NRM was associated with the NK dose (P = .024). In conclusion, in a PBSCT setting, a higher transplant dose of NK and Tc cells accelerated neutrophil engraftment, improved the immune reconstitution, and decreased NRM, thereby increasing OS after allogeneic PBSCT.

Abstract
BACKGROUND Little is known about the role of the CD56+ natural killer (NK) cell dose on the outcome of allogeneic peripheral blood stem cell transplantation (PBSCT). Recently, higher dose of NK cells has been associated with a lower incidence of severe graft-versus-host disease (GVHD). The current study attempted to evaluate the effect of the NK cell dose on transplant outcomes in allogeneic PBSCT setting. METHODS AND MATERIALS Sixty-one cytokine mobilized PBSC recipients were analyzed according to the infused dose of CD34+ cells and NK cells in relation to overall survival (OS), non-relapse mortality (NRM), GVHD, and infectious events. RESULTS The group received a higher dose of NK cells (> or =5 x 10(7)/kg) showed a lower incidence of NRM (P = 0.0186) and infectious events (P = 0.0107). In a multivariate analysis, a higher dose of NK cells was correlated to better transplant outcomes for NRM (P = 0.042) with CD34+ cell dose (P = 0.018), and for infectious events (P = 0.013) with CD34+ cell dose (P = 0.016). Higher NK cell infusion group also showed a faster immune recovery in serial measurements at days +90, +180, and +365. CONCLUSIONS High dose of NK cells may play an important role in improving transplant outcomes, in terms of reducing NRM and infectious events together with CD34+ cells.

Abstract
Eighty patients with chronic myeloid leukemia (CML) underwent T cell-depleted stem cell transplantation from an HLA-identical sibling, with add-back of donor T cells on days 30 to 45 and days 60 to 100 in patients in whom grade 2 or greater acute graft-versus-host disease (GVHD) developed. The outcomes for 54 patients with chronic-phase (CP) and 26 with advanced-phase (AP) disease were as follows: overall survival, 85% +/- 5% versus 36% +/- 10%; transplantation-related mortality (TRM), 13% +/- 5% versus 43% +/- 11%; and current leukemia-free survival, 76% +/- 6% versus 34% +/- 9%. The day-30 lymphocyte count (LC30) was strongly associated with outcome. For patients in CP with counts greater than the median of 0.30 x 10(9)/L, survival was 100% versus 70% +/- 9% (P = .003); current LFS 100% versus 56% +/- 9% (P = .002); and TRM 0% versus 26% +/- 8% (P = .006). Higher-than-median LC30 correlated significantly with molecular remission (MR) at 3, 6, and 12 months and with higher CD34 doses. Lymphocyte subset analysis performed in 20 patients available for phenotyping showed that LC30 was highly correlated with absolute CD56+CD3- natural killer cell numbers (NK30), which also predicted for survival and MR. CD34 cell dose, LC30, and NK30, but not day-30 CD3+ cell count, were highly correlated and were significant predictors of transplantation outcome. These results suggest that transplanted CD34 cell doses greater than 5 x 10(6)/kg may improve outcomes by increasing the early recovery of NK cells.

Abstract
Although the cure of acute leukaemia has improved significantly, many patients will still relapse and die. The unraveling of the molecular pathogenesis of acute leukaemia has lead to the identification of new prognostic factors and improved the detection of minimal residual disease. The treatment of relapsed acute leukaemia with chemotherapy remains unsatisfactory. Allogeneic or autologous blood and marrow transplant (BMT) can cure a subset of patients with relapsed acute leukaemia. The identification of the graft-vs-leukaemia (GVL) effect has lead to the development of donor lymphocyte infusions to re-induce remission in patients with relapsed leukaemia after allogeneic BMT and also stimulated the development of the less toxic nonmyeloablative allogeneic transplant approach. The identification of molecular targets of therapy and the development of monoclonal antibody-directed therapy has generated optimism. It is possible that combinations of chemotherapy, molecularly directed therapy, and immunotherapy may be combined to cure an increasing proportion of patients with acute leukaemia.

Abstract
There is controversy regarding the best approach to the management of patients with acute myeloid leukaemia (AML) in first remission (CR1). The impact of matched related allogeneic transplant in CR1 on the overall survival is equivocal, but what is not in doubt is a significant reduction in the relapse risk, compared to both autologous transplants and intensive chemotherapy, which is because of the allogeneic or the graft-versus-leukaemia (GVL) effect. Yet, this does not always translate to improved survival. T cell depletion (TCD) can reduce deaths related to graft-versus-host disease (GVHD) and its therapy, but might increase the relapse risk. The existing literature suggests that TCD is associated with a disease-free survival (DFS) of 53-80% and is associated with a lower relapse risk than anticipated (0-30%). We discuss the evolution of TCD in allogeneic transplantation and its relevance in AML-CR1 with regard to GVHD, DFS, immune reconstitution and GVL effect. It is possible that by reducing TRM related to GVHD and extramedullary toxicities, particularly in the older patients, TCD might improve the impact of allogeneic transplantation in AML-CR1, provided the immune reconstitution and the relapse risk are not adversely affected. Randomised studies are underway to address these issues.

Abstract
Sources for allogeneic stem cells for patients with haematological disorders lacking a histocompatible sibling donor include matched unrelated donor (MUD) and umbilical cord blood (UCB). A total of 51 patients with haematological disorders, treated with myeloablation and transplantation with either unrelated human leucocyte antigen (HLA) partially matched UCB (28 patients) or HLA-matched MUD grafts (23 patients) during 1997-2003, were evaluated for life-threatening infections, haematological reconstitution, graft versus host disease, relapse and event-free survival (EFS). The median duration of neutropenia after transplantation was longer (29 d vs. 14 d) in the UCB group. The probability of donor-derived neutrophil engraftment by day 42 was 0.86 [95% confidence interval (CI) 0.71-1.0] in UCB recipients versus 0.96 (95% CI 0.87-1.0) in MUD recipients surviving >28 d. Overall infection rates were higher in UCB recipients, particularly at the early time points (before day +50) after transplantation. Graft failure occurred in five UCB recipients and two MUD recipients and was associated with the occurrence of bacteraemia during neutropenia. The EFS at 3-year follow-up was 0.25 in UCB and 0.35 in MUD recipients. UCB transplantation in adults is associated with delayed neutrophil and lymphocyte recovery compared with MUD grafting, and higher rates of bacteraemia at early time points after transplantation.

Abstract
The role of repopulating lymphocytes after allogeneic stem cell transplantation (SCT) includes the prevention of serious infections and attacking residual tumour cells in the early post-transplant phase. Therefore, the current study analysed the role of the absolute lymphocyte count (ALC) on day 21 after SCT in predicting transplant outcomes of 82 patients in terms of the risk of opportunistic infections and recurrence of original disease. The median dose of CD34+, CD3+ and mononuclear cells (MNC) infused was 6.41 x 10(6)/kg, 1.96 x 10(8)/kg and 6.81 x 10(8)/kg respectively. The high ALC group (high ALC on day 21; > or =0.35 x 10(9)/l) was associated with the use of peripheral blood stem cells, matched sibling donors and higher cell doses of MNC, CD3+ and CD4+ cells. The high ALC group also exhibited a better overall survival (56.3% vs. 17.7%) and disease-free survival (50.1% vs. 15.9%) after 3 years and lower incidences of relapse (33.6% vs. 67.1%) and fungal infections (3.0% vs. 19.5%) after 1 year. The incidence of cytomegalovirus antigenaemia was lower in the high ALC group (47.7% vs. 73.7%). Accordingly, identifying the ALC on day 21 would appear to be a useful and simple measurement to predict those patients with a high risk of opportunistic infections and relapse after allogeneic SCT.

Abstract
Allogeneic blood and marrow transplantation (BMT) is curative for many patients with high-risk and relapsed acute lymphoblastic leukemia (ALL). However, relapse is an important cause of post-transplantation failure, and there are no reliable markers to predict relapse. A retrospective review of patients with ALL who underwent matched related allogeneic BMT was carried out to examine whether the rate of lymphocyte recovery after transplantation had any prognostic value in ALL. The absolute lymphocyte count (ALC) at days 21 and 30 after transplantation was obtained for 43 patients who received transplants during an 18-year period. Patients with an ALC of 175 x 10(6)/l or less on day 21 were more likely to relapse than those with ALC greater than 175 x 10(6)/l (relative risk, 4; 95% confidence interval, 1.5-11.2). Patients with slower lymphocyte recovery had significantly lower relapse-free survival than those with faster recovery (P=0.0028). There was also a trend toward poorer overall survival among those with a slow lymphocyte recovery (log-rank test; P=0.028). The rate of lymphocyte recovery is prognostic in patients with ALL undergoing allogeneic BMT, and this should be integrated with other predictors to identify patients at high risk of relapse. Such patients could be considered for interventions aimed at prevention of relapse, including rapid withdrawal of immunosuppressive medication or donor lymphocyte infusion.

Abstract
We evaluated the outcome of 29 patients (age 22-60 years), who received a CD34+selected related (n=16) or unrelated graft (n=13) with limited T-cell addback (TCAB) (median 5.9 x 10(4)/kg) following full-intensity conditioning for haematological malignancies. In all, 16 patients (55%) had either advanced disease or previous transplants. The cumulative incidences of grade 2-4 acute GVHD were 15.4 and 19.2% and that for chronic extensive GVHD were 35 and 37% in related and unrelated graft recipients, respectively. The strongest predictor of nonrelapse mortality and overall survival was the absolute lymphocyte count (ALC) at 30 days; patients with ALC<0.35 x 10(9)/l having an NRM and OS of 59.2 and 24.7%, compared to 10 and 90% in those with a higher ALC. Patients with acute leukaemia had poorer survival and this was associated with a lower ALC as well. Thus, TCAB with a CD34+ selected graft resulted in a comparable outcome in both older and younger patients, but the survival was strongly influenced by early lymphocyte recovery.

Abstract
We studied the outcome of 24 peripheral blood stem cell (PBSC) graft recipients, who were T-cell depleted (TCD) with either 20 mg (n = 14) or 10 mg (n = 10) Campath-1H in vitro, in comparison with a retrospective cohort of 23 unmanipulated (UM) PBSC recipients. While the neutrophil engraftment was similar, the platelet engraftment occurred earlier in the TCD group (d 11 vs 14). The incidence of acute and chronic graft-versus-host-disease (GVHD) was 8.7% and 4.4% in the TCD group, respectively, compared with 47.7% and 56.3% in UM group (P < 0.001). In the TCD group, 5/6 chronic myeloid leukaemia (CML) and 4/18 non-CML patients relapsed (vs 0/6 and 3/17 in UM group, P = 0.06). All four molecular or cytogenetic relapses of CML were disease-free survivors following donor lymphocyte infusion. There was no difference in the incidence of serious infection between the TCD and UM groups and the lymphocyte recovery at 100 d was comparable. In the TCD cohort, the lymphocyte recovery was quicker in the 10 mg Campath-1H group. The non-relapse mortality (19.1%vs 66.3%) and 3 year survival (73.1 vs 19.2) were improved in the TCD group (P = 0.05). Thus elimination of late mortalities related to chronic GVHD and a rapid immune reconstitution, limiting either infection or relapse related deaths, contributed to an improved outcome following T-cell depletion with Campath-1H "in the bag".
