Fifty patients with high-risk hematologic malignancies, underwent an unmanipulated haploidentical bone marrow transplantation (BMT), followed by posttransplantation high-dose cyclophosphamide (PT-CY): the myeloablative (MA) conditioning consisted of thiotepa, busulfan, fludarabine (n = 35), or total body irradiation (TBI), fludarabine (n = 15). The median age was 42 years (range, 18-66 years); 23 patients were in remission, 27 had active disease, and 10 patients were receiving a second allograft. Graft-versus-host disease (GVHD) prophylaxis consisted in PT-CY on day +3 and +5, cyclosporine (from day 0), and mycophenolate (from day +1). Three patients died before engraftment, and 2 patients had autologous recovery: 45 patients (90%) had full-donor chimerism on day +30. The median day for neutrophil engraftment was day +18 (range, 13-30 days). The cumulative incidence of grade II-III acute GVHD (aGVHD) was 12%, and of moderate chronic GVHD (cGVHD) 10%. With a median follow-up for surviving patients of 333 days (range, 149-623 days), the cumulative incidence of transplantation-related mortality (TRM) was 18%, and the rate of relapse was 26%. The actuarial 22-month disease-free survival (DFS) rate was 68% for patients in remission and 37% for patients with active disease (P < .001). Causes of death were pneumonia (n = 3), hemorrhage (n = 3), sepsis (n = 3), and relapse (n = 7). In conclusion, an MA conditioning regimen followed by haploidentical BMT with PT-CY results in a low risk of aGVHD and cGVHD and encouraging rates of TRM and DFS.

We studied 459 consecutive patients with hematologic malignancies, median age 44 years (range, 15 to 71 years), who underwent transplantation with grafts from identical sibling donors (SIB; n = 176), matched unrelated donors (MUD; n = 43), mismatched unrelated donors (mmUD; n = 43), unrelated cord blood (UCB; n = 105) or HLA-haploidentical family donors (HAPLO; n = 92). Graft-versus-host disease (GVHD) prophylaxis consisted of cyclosporine and methotrexate in the SIB recipients; antithymocyte globulin for the MUD, mmUD, and UCB recipients; and post-transplantation cyclophosphamide, cyclosporine, and mycophenolate in the HAPLO recipients. Conditioning regimens were mostly myeloablative (69%). Advanced disease phase was more frequent, but not significantly so, in the HAPLO and mmUD groups (P = .08). Acute GVHD grade II-IV was significantly less frequent in the HAPLO, UCB, and MUD groups (14% to 21%) compared with the SIB (31%) and mmUD (42%) groups (P < .001), and there was a trend toward less moderate-severe chronic GVHD in the HAPLO and UCB groups (P = .053). The proportion of patients off cyclosporine at 1 year ranged from 55% for the SIB group to 81% for the HAPLO group (P < .001). Transplantation-related mortality at 2 years was lower in the HAPLO and SIB groups (18% to 24%) compared with the MUD, mmUD, and UCB groups (33% to 35%; P = .10). Relapse rate was comparable in the 5 groups (P = .80). The 4-year actuarial survival was 45% in the SIB group, 43% in the MUD group, 40% in the mmUD group, 34% in the UCB group, and 52% in the HAPLO group (P = .10). In multivariate analysis, advanced disease was a negative predictor of survival (hazard ratio [HR], 2.4; P < .0001), together with a diagnosis of acute leukemia (HR, 1.8; P = .0001); HAPLO grafts were comparable to SIB (P = .80), whereas UCB had inferior survival (P = .03). In conclusion, unmanipulated haploidentical family donor transplants are an additional option for patients lacking a matched sibling donor.

Summary. The number of long-term survivors after allogeneic bone marrow transplantation (BMT) has been increasing over the past years, and quality of life (QOL) has become an important end-point. We studied 244 patients undergoing an allogeneic BMT to identify factors and events influencing psychosocial outcome. Patients enrolled received the Psychosocial Adjustment to Illness Scale (PAIS) questionnaire assessing psychological and social adjustment to chronic illness or its sequelae. Eightytwo per cent of patients had a haematological disease. The median age was 28 years at BMT, and the median follow-up was 61 months. The median overall PAIS score for all patients was 56 (range 22±76): 25% (n 61) of patients were considered to have a good QOL (# 25 percentile score); 44% (n 108) of patients had an intermediate QOL (26± 75 percentile score) and 31% (n 75) had a poor QOL (. 75 percentile score). Factors associated with a poor QOL in multivariate analysis were: patients' age at BMT (. 25 years, P , 0´01); presence of long-term sequelae (P , 0´01); chronic graft-versus-host disease (GVHD) (P , 0´05); and a short interval from BMT (, 5 years; P , 0´05). The QOL improved with time: 12% of patients reported a good QOL within 5 years compared with 38% after this time point and, conversely, 38% reported a poor QOL within 5 years compared with 24% after this time point (P , 0´0001). Older patients had significantly poorer QOL compared with younger patients (# 25 years; P 0´01). Females had significantly poorer scores when compared with males in the sexual (P , 0´0001) and psychological domains (P 0´001). The data suggest that (i) one-third of patients undergoing allogeneic BMT report a poor QOL; (ii) factors associated with poor QOL are older age, presence of long-term sequelae, chronic GVHD and short follow-up; (iii) QOL is superior in long-term survivors; and (iv) BMT affects different aspects of life in males and females. A longitudinal study is ongoing to prove the effect of time on quality of life.

Platelet recovery after allogeneic haemopoietic stem cell transplant (HSCT) and predictive factors were analysed in 342 patients with haematological malignancies. All patients were prepared with cyclophosphamide plus total body irradiation, and received an unmanipulated HSCT from an HLA‐identical sibling (n = 270), a matched unrelated donor (n = 67) or an identical twin (n = 5). The source of stem cells was peripheral blood (n = 15) or bone marrow (n = 327). Graft‐vs.‐host disease (GvHD) prophylaxis consisted of cyclosporin A with or without methotrexate. The proportion of patients with < 50 × 109/l platelets on d +50, d +100, d +200 and d +365 after HSCT was 26%, 27%, 14% and 11% respectively. Thrombocytopenia was independent of the degree of complete donor chimaerism. Four variables were predictive of platelet recovery: donor type, acute GvHD, cytomegalovirus (CMV) infection and number of cells infused at transplant. Recipients of an unrelated graft had lower platelet counts (49 × 109/l) on d +50 than identical sibling grafts (108 × 109/l) (P < 0·001) and twin grafts (149 × 109/l) (P < 0·001). Patients with GvHD grades 0, I, II, III and IV had significantly different platelet counts on d +50 (153 × 109/l, 102 × 109/l, 85 × 109/l, 32 × 109/l and 22 × 109/l; P < 0·001) and thereafter. Thrombocytopenia was more frequent in patients with high‐level CMV antigenaemia (> four positive cells/2 × 105) (P < 0·0001) and in patients who received a low cell dose at transplant (≤ 4·1 × 108/kg) (P = 0·009). Platelet counts predicted transplant‐related mortality (TRM) and were higher at all time intervals in patients surviving the transplant. Patients with grade II GvHD and > 50 × 109/l platelets had a lower TRM than patients with grade II GvHD and ≤ 50 × 109/l platelets (14% vs. 40%, P < 0·0001). In conclusion, (i) a significant proportion of allogeneic HSCT recipients are thrombocytopenic long‐term, irrespective of complete donor chimaerism, (ii) thrombocytopenia identifies patients at greater risk of lethal complications, and (iii) platelet recovery is influenced by GvHD, donor type, CMV infections and cell dose, not by stem cell source or other patient–disease‐related variables.

Invasive aspergillosis (IA) is a serious complication in patients undergoing allogeneic haematopoietic stem cell transplantation (HSCT), particularly from donors other than HLA-identical sibling. All 306 patients who underwent alternative donor HSCT between 01 January 1999 and 31 December 2006 were studied. Late IA was defined as occurring X40 days after HSCT. The median followup was 284 days (range, 1-2709). Donors were matched unrelated (n ¼ 185), mismatched related (n ¼ 69), mismatched unrelated (n ¼ 35) and unrelated cord blood (n ¼ 17). According to European Organization for Research and Treatment of Cancer/Mycoses Study Group criteria, 2 patients already had IA at HSCT, 23 had early IA and 20 had late IA (IA incidence 15%). Eight patients had proven and 37 probable IA. Multivariate analyses showed that significant predictors of IA were delayed neutrophil engraftment, extensive chronic GVHD (cGVHD), secondary neutropenia and relapse after transplant. Early IA was associated with active malignancy at HSCT, CMV reactivation and delayed lymphocyte engraftment. Late IA was predicted by cGVHD, steroid therapy, secondary neutropenia and relapse after HSCT. IA-related mortality among IA patients was 67% and was influenced by use of antithymocyte globulin, steroids, higher levels of creatinine, and lower levels of IgA and platelets. The outcome of IA depends on the severity of immunodeficiency and the status of the underlying disease.
