RESUMO

BACKGROUND: Results have been varied regarding the effect of donor age on the outcome of unrelated donor haemopoietic cell transplantation (HCT). AIMS: To determine the influence of donor age on adult unrelated donor HCT outcome in Australia. METHODS: Patients were included in the study if they were aged 16 years or above and underwent first allogeneic unrelated donor HCT in Australia for the indications of acute lymphoblastic leukaemia (ALL), acute myelogenous leukaemia (AML), chronic myelogenous leukaemia (CML) or myelodysplastic syndromes (MDS) between the years of 2001 and 2014 inclusive. The main outcome measure was overall survival (OS), which was tested against independent variables using univariate Kaplan-Meier methods and multivariate Cox regression. RESULTS: A total of 1158 unrelated donor HCT were represented in the data. Cumulative incidences of engraftment, transplant related mortality (TRM), acute graft-versus-host disease (GvHD), chronic GvHD and relapse were not significantly affected by donor age. OS probability at 5 years post-transplant was 48.3%. In multivariate analysis of OS, year of transplant 2001-2007, recipient age 40 years or greater, poor risk disease, human leukocyte antigen (HLA) match less than 6/6 and poor performance status at transplant (Karnofsky scale) were independently significant adverse OS risk factors. Donor age was not a significant risk factor for OS in univariate or multivariate analysis. CONCLUSIONS: The conclusion from this study was that donor age (up to 59 years) did not influence post-transplant outcome among adult unrelated donor HCT performed in Australia for haematologic malignancies.

RESUMO

Cardiac light chain (AL) amyloidosis is a condition with a very poor prognosis. We report a retrospective analysis comparing the traditional melphalan and dexamethasone protocol with cyclophosphamide, bortezomib and dexamethasone in late-stage cardiac AL amyloidosis. The primary end points were overall survival and haematological response. Both regimens provided meaningful responses in this difficult to treat patient group.

RESUMO

We conducted a study to analyze and report on indicators of hematopoietic cell transplant (HCT) physician time use and HCT center output measures. HCT centers in Australia and New Zealand (A&NZ) were invited to provide demographic and time use details for physicians participating in HCT patient care (HCT physicians). Resource details for adult and pediatric centers were included. From a total of 46 centers that were invited to participate, completed data were received from 37 centers (80%) representing 185 HCT physicians, with a median age of 48 (range, 33 to 72), of whom 31% were women. Just over half of HCT physicians cited prior work experience in large overseas HCT centers (97, 52%) and over one-third (79, 43%) possessed postgraduate qualifications other than specialist training. Total annual mean HCTs per HCT physician full-time equivalent (FTE) were 14.2 for centers performing both allogeneic and autologous HCT, 6.6 for autologous only centers, and 10.6 for all centers. For all HCT physicians surveyed the mean proportion of time spent on HCT related tasks was 31.7%. In A&NZ, for centers that perform both allografts and autografts, there was a mean of 4.0 allogeneic HCT annually per HCT bed, compared with 2.6 for the United States and 7.1 allogeneic HCT annually per HCT physician FTE (United States, 6.3). Projections of the A&NZ HCT physician workforce indicated that the numbers of HCT physicians are likely to stay within the region of 170 to 190 for the next 10 years, whereas HCT activity will likely continue to climb steadily. Healthcare and government authorities should be prepared to enable and support greater HCT activity in A&NZ in the future.

RESUMO

A previous study found that platelet recovery and mortality were worse in recipients of myeloablative bone marrow transplants where graft transit times were longer than 20 hours. This retrospective study of unrelated myeloablative allogeneic transplantation performed within Australia and New Zealand analyzed transplant outcomes according to graft transit times. Of 233 assessable cases, 76 grafts (33%) were sourced from bone marrow (BM) and 157 (67%) from peripheral blood. Grafts sourced from Australia and New Zealand (47% of total) were associated with a median transit time of 6 hours versus 32 hours for overseas sourced grafts (53% of total). Graft transit temperature was refrigerated in 85%, ambient in 6%, and unknown in 9% of cases, respectively. Graft transit times had no significant effect on neutrophil or platelet engraftment, treatment-related mortality, overall survival, and incidence of acute or chronic graft-versus-host disease. Separate analysis of BM grafts, although of reduced power, also showed no significant difference in either neutrophil or platelet engraftment or survival between short and longer transport times. This study gives reassurance that both peripheral blood stem cell and especially BM grafts subjected to long transit times and transported at refrigerated temperatures may not be associated with adverse recipient outcomes.

RESUMO

Despite the long history of bendamustine as treatment for indolent non-Hodgkin lymphoma, long-term efficacy and toxicity data are minimal. We reviewed long-term data from three clinical trials to characterize the toxicity and efficacy of patients receiving bendamustine. Data were available for 149 subjects at 21 sites. The median age was 60 years at the start of bendamustine (range 39-84), and patients had received a median of 3 prior therapies. The histologies included grades 1-2 follicular lymphoma (FL; n = 73), grade 3 FL (n = 23), small lymphocytic lymphoma (n = 20), marginal zone lymphoma (n = 15), mantle cell lymphoma (n = 9), transformed lymphomas (n = 5), lymphoplasmacytic lymphoma (n = 2) and not reported (n = 2). The median event-free survival was 14·1 months. Nine of 12 attempted stem cell collections were successful. With a median follow-up of 8·9 years, 23 patients developed 25 cancers, including 8 patients with myelodysplastic syndrome/acute myeloid leukaemia. These data provide important information regarding the long-term toxicity of bendamustine in previously treated patients. A small but meaningful number of patients achieved durable remissions following bendamustine. These rigorously collected, patient-level, long-term follow-up data provide reassurance that bendamustine or bendamustine plus rituximab is associated with efficacy and safety for patients with relapsed or refractory indolent non-Hodgkin lymphoma.

RESUMO

BACKGROUND: Hematopoietic stem cell transplantation (HSCT) is a life-saving procedure for children with a variety of non-malignant conditions. However, these children face an increased risk of late death and incident cancers after HSCT, which may occur many years after their initial HSCT. PROCEDURE: We examined cancer occurrence and late mortality in a population-based cohort of 318 Australian children who underwent allogeneic HSCT for non-malignant disease. Standardized incident ratios (SIRs) and standardized mortality ratios (SMRs) were calculated and compared with population controls. RESULTS: We identified six (1.9%) cancers at a median 9.2 years post-HSCT. Cancer occurred 15 times more frequently than in the general population (SIR 15.4, 95% CI = 6.9-34.2). Of the 198 patients who survived for at least 2 years post-HSCT, 11 (5.6%) died at a median 7.5 years post-HSCT. The mortality rate was 17 times higher than in the general population (SMR 17.5, 95% CI = 9.7-31.2). DISCUSSION: Children transplanted for non-malignant conditions require evidence-based survivorship programs to reduce excess morbidity and mortality.

RESUMO

This report describes hematopoietic cell transplantation (HCT) activity and outcome in Australia and New Zealand during the years 2005 to 2013. In 2013, 1018 autologous, 221 allogeneic with related donors, and 264 allogeneic with unrelated donors HCT were performed in 40 centers in Australia, with corresponding figures of 147, 39, and 47 in 6 centers in New Zealand. Annual numbers of HCT in 2013 increased, compared to 2005, by 25% in Australia and by 52% in New Zealand. The majority of both allogeneic and autologous HCT used peripheral blood as the stem cell source for all years studied. Major indications for transplantation were acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL), plasma cell disorders, and non-Hodgkin lymphoma (NHL). Overall survival probabilities at 5 years after transplantation for adult (16+) allogeneic first HCT recipients were 54.2% for ALL, 46.0% for AML, 48.4% for myelodysplastic syndromes, and 58.6% for NHL. Consistent patterns over time include a steady increase in HCT, particularly for older recipients, relatively constant numbers of allografts using cord blood, and a recent increase in the number of allografts with 2 or more HLA-mismatched related donors.

RESUMO

We quantified the risk of second cancer and late mortality in a population-based Australian cohort of 3273 adult (≥15 years) allogeneic hematopoietic stem cell transplant recipients (1992 to 2007). Most recipients received nonradiation-based conditioning and a peripheral blood graft from a matched related donor. Using record linkage with death and cancer registries, 79 second cancers were identified a median of 3.5 years after transplantation. The competing-risk adjusted cumulative incidence of second cancers was 3.35% (95% CI, 2.59 to 4.24) at 10 years, and the cancer risk relative to the matched general population was 2.10 (95% CI, 1.65 to 2.56). We observed an excess risk of melanoma and lip, tongue, esophagus, and soft tissue cancers. Cancer risk relative to the general population was elevated for those transplanted for lymphoma, some leukemia subtypes, and severe aplastic anemia, recipients who developed chronic graft-versus-host disease (cGVHD) and irrespective of radiation-based conditioning or stem cell source. In those alive 2 years after transplantation (n = 1463), the cumulative incidence of late mortality was 22.2% (95% CI, 19.7 to 24.9) at 10 years, and the risk of death relative to the matched general population was 13.8 (95% CI, 12.2 to 15.6). In multivariable modeling, risk of late death was reduced for females compared with males and those transplanted for chronic myeloid leukemia compared with acute myeloid leukemia; risk was increased for recipients with discordant sex donors, cGVHD, those undergoing second transplants, and disease relapse. Adults undergoing allogeneic transplantation have unique cancer and mortality risk profiles that continue to warrant prevention and surveillance activities targeted at high-risk subgroups.

RESUMO

We assessed overall and cause-specific mortality and risk factors for late mortality in a nation-wide population-based cohort of 4547 adult cancer patients who survived 2 or more years after receiving an autologous hematopoietic stem cell transplantation (HSCT) in Australia between 1992 and 2005. Deaths after HSCT were identified from the Australasian Bone Marrow Transplant Recipient Registry and through data linkage with the National Death Index. Overall, the survival probability was 56% at 10 years from HSCT, ranging from 34% for patients with multiple myeloma to 90% for patients with testicular cancer. Mortality rates moved closer to rates observed in the age- and sex-matched Australian general population over time but remained significantly increased 11 or more years from HSCT (standardized mortality ratio, 5.9). Although the proportion of deaths from nonrelapse causes increased over time, relapse remained the most frequent cause of death for all diagnoses, 10 or more years after autologous HSCT. Our findings show that prevention of disease recurrence remains 1 of the greatest challenges for autologous HSCT recipients, while the increasing rates of nonrelapse deaths due to the emergence of second cancers, circulatory diseases, and respiratory diseases highlight the long-term health issues faced by adult survivors of autologous HSCT.

RESUMO

The number of hematopoietic stem cell transplantations (HCTs) is increasing annually worldwide, and the Asia-Pacific (AP) region is no exception. We report on the absolute number of HCTs in 2018 and 2019 and the trends in graft selection and disease indication in the past few decades. In 2018, 24,292 HCTs were performed in the AP region, of which 8,754 (36.0%) were autologous and 15,538 (64.0%) were allogeneic. Among the allogeneic HCTs, 10,552 (67.9%) of the recipients were related to their donors, whereas 4,986 (32.1%) were unrelated. In 2019, 27,583 HCTs were reported, of which 17,613 (63.9%) were allogeneic and 9,970 (36.1%) were autologous. Although, in 2010, there was a nearly equal number of related and unrelated HCTs, the difference has shown an annual increase, with more than double (2.05) the number of related than unrelated HCTs in 2019. Recent trends in the AP region show that peripheral blood has overwhelmingly surpassed the bone marrow as a graft source for both related and unrelated HCTs, with the haploidentical donor type being preferred; however, their trends in each country/region were quite different among countries/regions. In 2019, the main conditions requiring HCT were acute myelogenous leukemia (n=6,629 [24.0%]), plasma cell disorders (PCD) (n=4,935 [17.9%]), malignant lymphoma (ML) (n=4,106 [14.9%]), acute lymphoblastic leukemia (AML) (n=3,777 [13.7%]), myelodysplastic syndrome or myelodysplastic/myeloproliferative neoplasm (n=1,913 [6.9%]), severe aplastic anemia (n=1,671 [6.1%]), and hemoglobinopathy (n=910 [3.3%]). PCD and ML were the main indications for autologous HCT, and the number of PCD cases has grown more prominent than the corresponding of ML. The increased number of allogeneic transplants for hemoglobinopathy remains prominent, as well as that of AML and acute lymphocytic leukemia for the past 5 years. There was a significant regional variation in the number of facilities performing HCTs, ranging from one in Mongolia and Nepal to 313 in Japan, and differing regional densities varying from 0.1 in Indonesia and Pakistan to 24.7 in Japan. The total transplant density per 10 million population in each country/region also differed (0.2 in Indonesia and 627 in New Zealand). This annual Activity Survey aims to help all participating countries/regions understand the changes in HCT, serve as an asset in promoting HCT activities in the AP region, and be used as a reference for comparison with other registries from Europe and the United States.

RESUMO

This retrospective registry analysis examined predictive factors for outcome in 57 patients who underwent allogeneic or syngeneic hematopoietic cell transplantation (HCT) for chronic myelofibrosis (CM), either primary (n = 49) or following an antecedent condition (n = 8), reported to the Australasian Bone Marrow Transplant Registry (ABMTRR) between 1993 and 2005. During the 6 years 2000 to 2005, 40 HCTs were performed for CM compared with 17 in the 7 years 1993 to 1999. Twenty-four recipients (42%) were age 50 or over at transplantation; all of these patients were transplanted after 1997, and 15 were given reduced intensity conditioning (RIC) pretransplantation. The cumulative incidence of transplantation-related mortality was 18% at 100 days and 25% at 1 year posttransplantation. Up to 1 year posttransplantation 16 patients died, with the most common causes being infection (n = 6) and graft-versus-host disease (GVHD) (n = 5). A total of 27 patients survived for 3 years or longer posttransplantation. None of these patients required regular red blood cell transfusions, and of the 17 who had not had splenectomies, none had detectable splenomegaly. Twelve patients had no detectable bone marrow fibrosis, 7 had grade 1 fibrosis, and in 8 patients no information was available. The overall survival (OS) probability for all patients was 72% at 1 year and 58% at 5 years posttransplantation. Patients age 50 and over who received myeloablative conditioning fared poorly, with 1-year overall actuarial survival of 44% compared with 77% for all other patients (P = .007). In multivariate analysis, age 50 years and over at transplantation was the only significant independent unfavorable risk factor for survival post-HCT (hazard ratio 2.71, 95% confidence interval 1.16-6.34, P = .02). This study shows a clear increase in annual numbers of allogeneic HCT performed for CM in Australia and New Zealand in recent years. Five-year survival was favorable compared with international studies, but for older recipients who received myeloablative conditioning, mortality risk was elevated.

RESUMO

The Asia-Pacific Blood and Marrow Transplantation Group (APBMT) has been conducting annual surveys on the activity of hematopoietic stem cell transplants since 2007. The APBMT Data Center collected the following data in 2017. A total of 21,504 transplants were registered from 733 transplant centers of 20 countries/regions in the Asia-Pacific (AP) region. Five countries/regions comprised 89.4% of all transplants - China (6,979), Japan (5,794), South Korea (2,626), India (2,034), and Australia (1,789). The number of centers in these five countries/regions also comprised 88.9% of all centers: Japan (373), China (123), India (66), Australia (45), and South Korea (44). The overall ratio between autologous and allogeneic transplants was 37.0% and 63.0%, respectively, but the ratios varied significantly among countries/regions. Autologous transplants have surpassed allogeneic transplants in Thailand, Australia, Vietnam, New Zealand, Singapore, and Iran. In contrast, the proportion of allogeneic transplants comprised over 70% of all transplants in Pakistan, China, and Hong Kong. These ratios were compared by the Data Center among countries/regions that performed more than 50 transplants. The proportion of related and unrelated transplants also differed among countries/regions. The number of unrelated transplants was more than related ones in Japan (2,551 vs. 1,202) and Australia (329 vs. 291), whereas more than 80% of all transplants were related transplants in Malaysia (90.9%), India (89.5%), Iran (87.2%), Vietnam (85.7%), China (80.9%), and Thailand (80.6%). All transplant activities were related transplants in Pakistan, the Philippines, Myanmar, and Nepal, and no allogeneic transplants were performed in Bangladesh and Mongolia. Regarding the indications for transplants, acute myeloid leukemia (AML) was the most common disease for allogeneic transplant (4,759, 35.1% of allogeneic transplants), while plasma cell disorder (PCD) was the most common disease for autologous transplant (3,701, 27.3% of all autologous transplants). Furthermore, the number of transplants for hemoglobinopathy has steeply increased in this region compared with the rest of disease indications (677, 3.1% of all transplants). APBMT covers a broad area globally, including countries/regions with diverse disease distribution, development of HSCT programs, population, and economic power. Consistent and continuous activity surveys considering those elements in each country/region revealed the HSCT field's diverse characteristics and background factors in this region.

RESUMO

This report describes the results of the Asia-Pacific Blood and Marrow Transplantation Group (APBMT) Activity Survey 2016, focusing on the trends of haploidentical and cord blood (CB) transplants in the Asia-Pacific region. Mongolia and Nepal submitted their first activity data in this survey, and the number of countries/regions participating in the activity survey grew to 20. The annual number of transplants exceeded 20,000 for the first time in 2016, and the total number of centers increased to 686. About 87.9% of all hematopoietic stem cell transplantations (HSCTs) were performed in China, Japan, Korea, India, and Australia with China performing the highest number. Beginning with the 2016 survey, APBMT modified the survey forms and initiated the collection of the exact number of haploidentical transplants. The total number of such transplants was 3,871, and 66.0% of those were performed in China. Meanwhile, cord blood transplants in this region remained high (1,612), and 81.8% of them (1,319) were performed in Japan. The number of facilities and transplants, the ratio of haploidentical transplants to related transplants, the ratio of CB transplants to unrelated transplants, and proportions of haploidentical and CB transplants per capita significantly differed among countries/regions in the Asia-Pacific region. Data collection and analysis revealed the transition and diversity of transplants in this region. This report also shows a dramatic increase in haploidentical transplants as seen in other parts of the world, while revealing uniquely that the activity of cord blood transplant remains high in this region.

RESUMO

The long-term follow-up is presented for 317 patients with acute myeloid leukaemia who underwent human leucocyte antigen-identical sibling marrow transplants between 1984 and 1995 following preparation with busulfan 16 mg/kg and cyclophosphamide 120 mg/kg. Among the 142 (45%) who were alive and leukaemia-free 3 years following transplantation, the leukaemia-free survival at 15 years was 72.8%. The cumulative incidence of late (>3 years beyond transplant) non-relapse mortality at 15 years was 12.9% and of late relapse was 16.5%. None of the variables considered (including age, disease stage, and graft-versus-host disease) were predictive of late failure.

RESUMO

Whether the annual mortality rates of long-term hematopoietic cell transplant (HCT) survivors ever return to that of the general population is unclear. This study sought to determine the annual long-term mortality rates of allogeneic and autologous HCT recipients who had survived 5 years or more disease-free posttransplant and calculate their relative survival rates. Patients were included if they had a first allogeneic or syngeneic HCT for acute leukemia, chronic myelogenous leukemia (CML) or myelodysplastic syndromes (MDS), or autologous HCT for acute myelogenous leukemia (AML) or lymphoma in Australia or New Zealand between 1992 and 2001, recorded on the Australasian Bone Marrow Transplant Recipient Registry (ABMTRR) database, and were known to have survived, disease free, 5 years or more posttransplant. The annual mortality rates of 5-year transplant survivors were compared to standard Australian and New Zealand populations using relative survival. A total of 1461 HCT survivors (688 postallograft, 773 postautograft) were included in this study. The 10-year survival probability for 5-year allograft survivors was slightly higher than that of 5-year autologous survivors (93.4% versus 89.6%, P=.06). The relative survival of both allogeneic and autologous 5-year survivors was never <97% of that of the general population. However, it was statistically significantly lower than expected in the sixth to ninth years posttransplant, with no obvious pattern of either improvement or deterioration from 6 to 10 years posttransplant. This study indicates that annual relative survival rates of long-term survivors of allogeneic HCT performed in Australia and New Zealand for acute lymophoblastic leukemkia (ALL), AML, CML, and MDS are slightly, but significantly lower than population rates in the 6th to 10th years posttransplant. Annual relative survival rates of long-term survivors of autologous HCT performed in Australia and New Zealand for AML and lymphomas are also slightly lower than population rates up to the 10th year posttransplant. Late deaths from transplant and disease-related causes are unusual, but continue to occur for many years post-HCT.

RESUMO

Allogeneic hematopoietic stem cell transplantation (HSCT) is the only known curative therapy for chronic myelogenous leukemia (CML). Failure, because of relapse or nonrelapse mortality (NRM), generally occurs within 3 years of transplantation, but large studies with long-term follow-up are limited. We present mature results in 335 patients with CML who underwent allogeneic bone marrow transplantation (BMT) from HLA-identical siblings following busulfan and cyclophosphamide (BU/Cy2). Two hundred twenty-nine were in chronic phase (CP) and 106 in accelerated or blastic phase at transplantation. Median follow-up exceeded 14 years. The estimated probability of 18-year leukemia-free survival (LFS) for CP patients was 55.6% and for those beyond CP, 10.5%. Of 182 patients who survived leukemia-free at 3 years, the estimated probability of LFS at 18 years was 61.9%. Late relapse (P = .039) and late NRM (P = .008) occurred at higher rates in patients beyond CP at transplantation. There was no plateau in LFS.

RESUMO

Between 2005 and 2015, 138,165 hematopoietic stem cell transplantation (HSCT) were reported in 18 countries/regions in the Asia-Pacific region. In this report, we describe current trends in HSCT throughout the Asia-Pacific region and differences among nations in this region and various global registries. Since 2008, more than 10,000 HSCTs have been recorded each year by the Asia-Pacific Blood and Marrow Transplantation Group Data Center. Between 2005 and 2015, the greatest increase in the number of HSCTs was observed in Vietnam. Allogeneic HSCT was performed more frequently than autologous HSCT, and a majority of cases involved related donors. Regarding allogeneic HSCT, the use of cord blood has remained steady, especially in Japan, and the number of cases involving related HLA non-identical donors has increased rapidly, particularly in China. The incidence of hemoglobinopathy, a main indication for allogeneic HSCT in India, China, Iran, and Pakistan, increased nearly six-fold over the last decade. Among the 18 participating countries/regions, the transplant rate per population varied widely according to the absolute number of HSCTs and the national/regional population size. We believe that this report will not only benefit the AP region but will also provide information about HSCT to other regions worldwide.

RESUMO

BACKGROUND: Preclinical studies suggest granulocyte-colony stimulating factor (G-CSF) holds promise for treating ischemic heart disease; however; its clinical safety and efficacy in this setting remain unclear. We elected to evaluate the safety and efficacy of G-CSF administration in patients with refractory "no-option" ischemic heart disease. METHODS: Twenty patients (18 males, 2 females, mean age 62.4 years) were enrolled and underwent baseline cardiac ischemia assessment (CA) (angina questionnaire, exercise stress test [EST], technetium Tc 99m sestamibi and dobutamine-stress echocardiographic imaging). Patients then received open-label G-CSF commencing at 10 microg/kg SC for 5 days, with an EST on days 4 and 6 (to facilitate myocardial cytokine generation and stem cell trafficking). After 3 months, CA and the same regimen of G-CSF+ESTs were repeated but, in addition, leukapheresis and a randomized double-blinded intracoronary infusion of CD133+ or unselected cells were performed. Final CA occurred 3 months thereafter. RESULTS: There were no deaths, but only 16 patients were permitted to complete the study. Eight events fulfilled prespecified "adverse event" criteria, including 4 troponin I-positive events and 2 episodes of thrombocytopenia. Also, frequent minor troponin I-positive events (troponin I<0.9 microg/L) were observed, which did not meet adverse event criteria. The administration of consecutive cycles of G-CSF resulted in stepwise improvements in anginal frequency, EST performance, and Duke treadmill scores (all P<.005). However, from baseline to final follow-up, technetium Tc 99m sestamibi and dobutamine-stress echocardiographic results were unchanged. CONCLUSIONS: Granulocyte-colony stimulating factor administration was associated with improvement in a range of subjective outcomes. However, adverse events were common, and objective measures of cardiac perfusion/ischemia were unchanged.

RESUMO

SUMMARY: Diamond-Blackfan anaemia (DBA) is a rare cause of bone marrow failure. The incidence of malignancy and endocrine complications are increased in DBA, relative to other inherited bone marrow failure syndromes. We describe an adult woman with DBA who developed osteoporosis and avascular necrosis (AVN) of both distal femora. Such endocrine complications are not uncommon in DBA, but under-appreciated, especially in adulthood. Further, rectal adenocarcinoma was diagnosed at age 32 years, requiring hemi-colectomy and adjuvant chemotherapy. Elevated cancer risk may warrant disease-specific screening guidelines. Genetic predictors of extra-haematopoetic complications in DBA are yet to be established. LEARNING POINTS: Endocrine complications are common in DBA.Clinical vigilance is required in managing bone health of DBA patients treated with glucocorticoids.There is currently no reliable way to predict which patients will develop complications of therapy or premature malignancy related to DBA.Complaints of bone or joint pain should prompt screening with targeted magnetic resonance imaging. Osteoporosis screening should be performed routinely.

RESUMO

BACKGROUND: Heart and lung transplant recipients have among of the highest incidence rates of post-transplant lymphoproliferative disease (PTLD). Despite this, there is a paucity of data specific to this group. We collated data on heart, lung and heart-lung transplant recipients with PTLD to identify disease features and prognostic factors unique to this group of patients. METHODS: Seventy cases of PTLD were identified from a single institution (41 heart, 22 lung, 6 heart-lung and 1 heart-kidney transplant) from 1984 to 2013. Demographics, immunosuppression, treatment, response, complications and survival data were analyzed. Uni- and multivariate Cox regression analyses were performed to identify prognostic factors. RESULTS: The incidence of PTLD was 7.59% in heart-lung, 5.37% in heart and 3.1% in lung transplant recipients. Extranodal disease (82%) with diffuse large B-cell lymphoma (72%) was the most common presentation. Bone marrow involvement (13%) and central nervous system disease (3%) were uncommon. Heart transplant recipients had later onset of PTLD (>1 year post-transplant), with less allograft involvement, compared with lung and heart-lung recipients. Poor prognostic markers were bone marrow involvement (HR 6.75, p < 0.001) and serum albumin <30 g/liter (HR 3.18, p = 0.006). Improved survival was seen with a complete response within 3 months of treatment (HR 0.08, p < 0.001). Five-year overall survival was 29%. CONCLUSION: This analysis is the largest to date on PTLD in heart and lung transplant recipients. It provides a detailed analysis of the disease in this group of patients and identifies unique prognostic features to aid risk stratification and guide treatment allocation.
