Abstract
BACKGROUND Cyclosporine A (CsA) is used widely for graft-versus-host disease (GVHD) prophylaxis in hematopoietic stem cell transplantation (HSCT); however, the optimal schedule of its administration has not been established. Although comparative studies of adult patients undergoing HSCT have demonstrated enhanced efficacy and safety of twice-daily infusion (TD) compared with continuous infusion (CIF) of CsA, to our knowledge, similar studies have not yet been performed in pediatric groups. PROCEDURE A self-administered questionnaire was used to retrospectively compare the clinical outcome and incidence of CsA-associated adverse events of 70 pediatric acute myelogenous leukemia patients who were receiving CsA by TD (n = 36) or CIF (n = 34) as GVHD prophylaxis for their first allogeneic HSCT. RESULTS The cumulative incidences of grade II-IV acute GVHD and chronic GVHD, as well as the overall survival and event-free survival rates, did not differ significantly between the TD and CIF groups; however, the incidence of severe hypertension was significantly higher in the CIF group than the TD group. CONCLUSIONS The analysis presented here indicates that TD and CIF administration of CsA have similar prophylactic effect on pediatric GVHD and suggest that TD is associated with a lower rate of toxicity than CIF in pediatric patients undergoing HSCT.

Early left ventricular dysfunction in children after hematopoietic stem cell transplantation for acute leukemia: a case control study using speckle tracking echocardiography.

Abstract
Background and Objectives Cardiovascular complications are the leading cause of morbidity and mortality in childhood cancer survivors. Hematopoietic stem cell transplantation (HSCT) is a curable therapy for pediatric cancer. However, changes in cardiac function in children after HSCT are not well known. We assessed left ventricular (LV) function in children after HSCT using speckle tracking echocardiography (STE). Subjects and Methods Forty consecutive patients with median age of 11.9 years (range, 1.5-16 years) who received HSCT for acute leukemia and had comprehensive echocardiography before and after (median 9.2 month) HSCT were included in this study. The LV function parameters including conventional tissue Doppler imaging (TDI) and STE data were collected from pre- and post-HSCT echocardiography. These data were compared to those of 39 age-matched normal controls. Results Compared to normal controls, post HSCT patients had similar (p=0.06) LV ejection fraction. However, the following three LV function parameters were significantly decreased in post HSCT patients: rate-corrected velocity of circumferential fiber shortening (p=0.04), mitral inflow E velocity (p<0.001), and mitral septal annular E' velocity (p=0.03). The following four STE parameters were also significantly decreased in post HSCT patients: LV global circumferential systolic strain (p<0.01), strain rate (SR, p=0.01), circumferential diastolic SR (p<0.01), and longitudinal diastolic SR (p<0.001). There was no significant change in TDI or STE parameters after HSCT compared to pre-HSCT. Patients with anthracycline cumulative dose >400 mg/m2 showed significantly (p<0.05) lower circumferential systolic strain and circumferential diastolic SR. Conclusion Subclinical cardiac dysfunction is evident in children after HSCT. It might be associated with pre-HSCT anthracycline exposure with little effect of conditioning regimens. Serial monitoring of cardiac function is mandatory for all children following HSCT.

Abstract
As survival rates in allogeneic hematopoietic stem cell transplantation (HSCT) continue to improve, attention to long-term complications, including cardiovascular disease, becomes a major concern. Cardiovascular disease and dyslipidemia are a common, yet often overlooked occurrence post-HSCT that results in significant morbidity and mortality. Also, increasing evidence shows that several anti-hyperlipidemia medications, the 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors in particular, may have a role in modulating graft-versus-host disease (GVHD). However, factors such as drug-drug interactions, adverse effect profiles, and the relative efficacy in lowering cholesterol and triglyceride levels must be taken into account when choosing safe and effective lipid-lowering therapy in this setting. This review seeks to provide guidance to the clinician in the management of dyslipidemia in the allogeneic HSCT population, taking into account the recently published American College of Cardiology/American Heart Association guidelines on hyperlipidemia management, special considerations in this challenging population, and the evidence for each agent's potential role in modulating GVHD.

Abstract
Standard carfilzomib (20 mg/m(2) cycle 1, 27 mg/m(2) thereafter; 2- to 10-minute infusion) is safe and effective in relapsed or refractory multiple myeloma (R/RMM). We report phase 2 results of carfilzomib 20 mg/m(2) on days 1 to 2 of cycle 1, 56 mg/m(2) thereafter (30-minute infusion), in R/RMM with the option of adding dexamethasone (20 mg) for suboptimal response/progression. Forty-four patients enrolled, all having prior bortezomib and immunomodulatory drugs and a median of 5 prior regimens. Of 42 response-evaluable patients, 23 (55%) achieved at least partial response (PR). Median (95% confidence interval) duration of response, progression-free, and overall survival were 11.7 (6.7-14.7), 4.1 (2.5-11.8), and 20.3 months (6.4-not estimable), respectively. High-risk cytogenetics did not impact outcomes. Treatment was active in bortezomib-refractory subgroups, but these patients tended to have poorer outcomes. Four/10 patients with prior allogeneic transplant achieved at least PR. Of 6 patients who responded, progressed and had dexamethasone added, 4 achieved at least stable disease. The most frequent grade 3/4 adverse events (AEs) possibly related to carfilzomib included lymphopenia (43%), thrombocytopenia (32%), hypertension (25%), pneumonia (18%), and heart failure (11%). Seven patients (16%) discontinued treatment due to AEs. Carfilzomib 56 mg/m(2) ± dexamethasone was tolerable and provided durable responses. This trial was registered at www.clinicaltrials.gov as #NCT01351623.

Abstract
The increasing number of haemopoietic stem cell transplantations (HSCT) taking place worldwide has offered a cure to many high risk childhood malignancies with an otherwise very poor prognosis. However, HSCT is associated with an increased risk of morbidity and premature death, and patients who have survived the acute complications continue to face lifelong health sequelae as a result of the treatment. Endocrine dysfunction is well described in childhood HSCT survivors treated for malignancies. The endocrine system is highly susceptible to damage from the conditioning therapy, such as, alkylating agents and total body irradiation, which is given prior stem cell infusion. Although not immediately life-threatening, the impact of these abnormalities on the long term health and quality of life in these patients may be considerable. The prevalence, risk factors, clinical approaches to investigations and treatments, as well as the implications of ongoing surveillance of endocrine disorders in childhood HSCT survivors, are discussed in this review.

Abstract
The authors sought to better understand the combined effects of pretransplant, transplant, and post-transplant factors in determining risks of serious cardiovascular disease after hematopoietic cell transplantation (HCT). Hospitalizations and deaths associated with serious cardiovascular outcomes were identified among 1379 Washington State residents who received HCT (57% allogeneic and 43% autologous) at a single center from 1985 to 2005, survived ≥ 2 years, and followed through 2008. Using a nested case-cohort design, relationships (hazard ratios [HRs]) between potential risk factors and outcomes were examined among affected survivors and a randomly selected subcohort (N = 509). After 7.0 years of median follow-up (range, 2.0 to 23.7), the 10-year cumulative incidence of ischemic heart disease, cardiomyopathy, stroke, and all-cause cardiovascular death was 3.8%, 6.0%, 3.5%, and 3.7%, respectively. In multivariable analysis, increased pretransplant anthracycline was associated with cardiomyopathy. Active chronic graft-versus-host disease was associated with cardiovascular death (HR, 4.0; 95% confidence interval, 1.1 to 14.7); risk was otherwise similar between autologous versus allogeneic HCT recipients. Independent of therapeutic exposures, pretransplant smoking, hypertension, dyslipidemia, diabetes, and obesity conferred additional risk of all outcomes except stroke (HR ≥ 1.5 for each additional risk factor, P < .03). Hypertension and dyslipidemia at 1 year with persistence of these conditions 2 or more years after HCT also were associated with independent risks of multiple outcomes. HCT survivors with preexisting or newly developed and persistent cardiovascular risk factors remain at greater risk of subsequent serious cardiovascular disease compared with other survivors, independent of chemo- and radiotherapy exposures. These survivors should receive appropriate follow-up and be considered for primary intervention.

Abstract
PURPOSE To determine the influence of modifiable lifestyle factors on the risk of cardiovascular disease after hematopoietic cell transplantation (HCT). PATIENTS AND METHODS HCT survivors of ≥ 1 year treated from 1970 to 2010 (n = 3,833) were surveyed from 2010 to 2011 on current cardiovascular health and related lifestyle factors (smoking, diet, recreational physical activity). Responses (n = 2,362) were compared with those from a matched general population sample (National Health and Nutrition Examination Survey [NHANES]; n = 1,192). RESULTS Compared with NHANES participants, HCT survivors (median age, 55.9 years; median 10.8 years since HCT; 71.3% allogeneic) had higher rates of cardiomyopathy (4.0% v 2.6%), stroke (4.8% v 3.3%), dyslipidemia (33.9% v 22.3%), and diabetes (14.3% v 11.7%; P < .05 for all comparisons). Prevalence of hypertension was similar (27.9% v 30.0%), and survivors were less likely to have ischemic heart disease (6.1% v 8.9%; P < .01). Among HCT survivors, hypertension, dyslipidemia, and diabetes were independent risk factors for ischemic heart disease and cardiomyopathy, and smoking was associated with ischemic heart disease and diabetes (odds ratios [ORs], 1.8 to 2.1; P = .02). Obesity was a risk factor for post-transplantation hypertension, dyslipidemia, and diabetes (ORs ≥ 2.0; P < .001). In contrast, lower fruit/vegetable intake was associated with greater risk of dyslipidemia and diabetes (ORs, 1.4 to 1.8; P ≤ .01), and lower physical activity level was associated with greater risk of hypertension and diabetes (ORs, 1.4 to 1.5; P < .05). Healthier lifestyle characteristics among HCT survivors attenuated risk of all cardiovascular conditions assessed. CONCLUSION Attention of clinicians to conventional cardiovascular risk factors and modifiable lifestyle characteristics offers hope of reducing serious cardiovascular morbidity after HCT.

Abstract
Hematopoietic cell transplantation (HCT) is increasingly offered as a curative option for many patients with hematologic malignancies. Improvements in HCT strategies and supportive care have resulted in a growing number of long-term survivors. However, these survivors are at an increased risk of developing long-term debilitating chronic health conditions, including premature cardiovascular disease. These complications are more common than in the general population, and there are well-described associations between therapeutic exposures, traditional cardiovascular risk factors, and subsequent cardiovascular disease risk. The authors present herein an overview of the current state of knowledge regarding pathogenesis and risk factors for some of the more commonly occurring cardiovascular complications after HCT, highlighting existing surveillance recommendations and future directions for research to minimize cardiovascular morbidity in these survivors.

Male survivors of allogeneic hematopoietic stem cell transplantation have a long term persisting risk of cardiovascular events. Exp Hematol 2013; 42:83-9.

Abstract
Long-term survivors of allogeneic stem cell transplantation (SCT) have increased risk of cardiovascular disease. We retrospectively studied cardiovascular risk factors (CVRFs) in 109 SCT survivors (62 males, 47 females; median age 34 years) five years or more after bone marrow (15) or T cell-depleted peripheral blood (94) SCT for CML (56), acute leukemia (29), MDS (13), and others (11). One death and two cardiovascular events were reported. At five and ten years after SCT, respectively, 44% and 52% had abnormal lipid profiles; 23% of 5-year survivors met the Adult Treatment Panel III threshold for dyslipidemia treatment, which is substantially higher than the age-matched general population. There were significant increases in prevalence of hypertension (p < 0.001), diabetes (p = 0.018), and body mass index (p = 0.044) after SCT compared with baseline. The Framingham general cardiovascular risk score (FGCRS) in males at five years after SCT projected a doubling (median 10.4% vs. 5.4%) in the 10-year risk of cardiovascular events. Females received HRT after SCT, and none had increased FGCRS. Chronic GVHD and C-reactive protein were not associated with CVRF at any time. All CVRFs stabilized between five and ten years after SCT. Thus, SCT survivors have sustained elevations in CVRFs. Males have a significantly increased risk of cardiovascular events in their second and third decade after SCT.

Abstract
Haematopoietic cell transplantation (HCT) survivors are at increased risk for developing congestive heart failure (CHF), primarily due to pre-HCT exposure to anthracyclines. We examined the association between the development of CHF after HCT and polymorphisms in 16 candidate genes involved in anthracycline metabolism, iron homeostasis, anti-oxidant defence, and myocardial remodelling. A nested case-control study design was used. Cases (post-HCT CHF) were identified from 2950 patients who underwent HCT between 1988 and 2007 at City of Hope and had survived ≥1 year. This cohort formed the sampling frame for selecting controls (without CHF) matched on: age, race/ethnicity, cumulative anthracycline exposure, stem cell source (allogeneic, autologous), and length of follow-up. Seventy-seven cases with pre-HCT germline DNA and 178 controls were genotyped. Multivariate analysis revealed that the odds of CHF was higher in females [Odds Ratio (OR) = 2·9, P < 0·01], individuals with pre-HCT chest radiation (OR = 4·7, P = 0·05), hypertension (OR = 2·9, P = 0·01), and with variants of genes coding for the NAD(P)H-oxidase subunit RAC2 (rs13058338, 7508T→A; OR = 2·8, P < 0·01), HFE (rs1799945, 63C→G; OR = 2·5, P = 0·05) or the doxorubicin efflux transporter ABCC2 (rs8187710, 1515G→A; OR = 4·3, P < 0·01). A combined (clinical and genetic) CHF predictive model performed better [area under the curve (AUC), 0·79] than the genetic (AUC = 0·67) or the clinical (AUC = 0·69) models alone.

Abstract
In the context of modern cancer chemotherapeutics, cancer survivors are living longer and being exposed to potential comorbidities related to non-cancer side effects of such treatments. With close monitoring of cancer patients receiving potentially cardiotoxic medical therapies, oncologists, and cardiologists alike are identifying patients in both clinical and subclinical phases of cardiovascular disease related to such chemotherapies. Specifically, cardiotoxicity at the level of the myocardium and potential for the development of heart failure are becoming a growing concern with increasing survival of cancer patients. Traditional chemotherapeutic agents used commonly in the treatment of breast cancer and hematologic malignancies, such as anthracyclines and HER-2 antagonists, are well known to be associated with cardiovascular sequelae. Patients often present without symptoms and an abnormal cardiac imaging study performed as part of routine evaluation of patients receiving cardiotoxic therapies. Additionally, patients can present with signs and symptoms of cardiovascular disease months to years after receiving the chemotherapies. As the understanding of the physiology underlying the various cancers has grown, therapies have been developed that target specific molecules that represent key aspects of physiologic pathways responsible for cancer growth. Inhibition of these pathways, such as those involving tyrosine kinases, has lead to the potential for cardiotoxicity as well. In view of the potential cardiotoxicity of specific chemotherapies, there is a growing interest in identifying patients who are at risk of cardiotoxicity prior to becoming symptomatic or developing cardiotoxicity that may limit the use of potentially life-saving chemotherapy agents. Serological markers and novel cardiac imaging techniques have become the source of many investigations with the goal of screening patients for pre-clinical cardiotoxicity. Additionally, studies have been performed.

Abstract
This review highlights long-term and late consequences of hematopoietic cell transplantation (HCT) as well as strategies to manage or prevent complications that are more prevalent after HCT than most other cancer treatments. Chronic graft-versus-host disease stands out as a unique late effect of allogeneic HCT that is not seen after other types of cancer treatment. However, many other complications seen after solid tumor treatments are also common after HCT, including infections, second cancers, bone loss, and cardiovascular, pulmonary, renal, and endocrine dysfunction. Symptoms and syndromes that are reported after HCT include sexual dysfunction, cognitive problems, fatigue, insomnia, musculoskeletal symptoms, emotional distress, anger, and depression. Addressing these complex potential or actual complications requires diligent routine health care to intervene early or, when possible, to prevent late complications. To accomplish early detection and prevention of life-threatening complications, HCT survivors should undergo an annual comprehensive physical examination that includes screening for functional and psychosocial consequences of treatment and encouraging healthy lifestyle behaviors. Clinicians can link survivors to numerous online, print, and video resources to help them advocate for their health needs.

Abstract
Existing standards for screening and management of late effects occurring in children who have undergone hematopoietic cell transplantation (HCT) include recommendations from pediatric cancer networks and consensus guidelines from adult-oriented transplantation societies applicable to all HCT recipients. Although these approaches have significant merit, they are not pediatric HCT-focused, and they do not address post-HCT challenges faced by children with complex nonmalignant disorders. In this article we discuss the strengths and weaknesses of current published recommendations and conclude that pediatric-specific guidelines for post-HCT screening and management would be beneficial to the long-term health of these patients and would promote late effects research in this field. Our panel of late effects experts also provides recommendations for follow-up and therapy of selected post-HCT organ and endocrine complications in pediatric patients.

Abstract
Long-term complications after hematopoietic cell transplantation (HCT) have been studied in detail. Although virtually every organ system can be adversely affected after HCT, the underlying pathophysiology of these late effects remain incompletely understood. This article describes our current understanding of the pathophysiology of late effects involving the gastrointestinal, renal, cardiac, and pulmonary systems, and discusses post-HCT metabolic syndrome studies. Underlying diseases, pretransplantation exposures, transplantation conditioning regimens, graft-versus-host disease, and other treatments contribute to these problems. Because organ systems are interdependent, long-term complications with similar pathophysiologic mechanisms often involve multiple organ systems. Current data suggest that post-HCT organ complications result from cellular damage that leads to a cascade of complex events. The interplay between inflammatory processes and dysregulated cellular repair likely contributes to end-organ fibrosis and dysfunction. Although many long-term problems cannot be prevented, appropriate monitoring can enable detection and organ-preserving medical management at earlier stages. Current management strategies are aimed at minimizing symptoms and optimizing function. There remain significant gaps in our knowledge of the pathophysiology of therapy-related organ toxicities disease after HCT. These gaps can be addressed by closely examining disease biology and identifying those patients at greatest risk for adverse outcomes. In addition, strategies are needed for targeted disease prevention and health promotion efforts for individuals deemed at high risk because of their genetic makeup or specific exposure profile.

Abstract
An increased incidence of cardiovascular complications has been documented in recipients of allogeneic hematopoietic stem cell transplantation (HSCT). Despite this, little is known about the risk factors for hyperlipidemia or the role of lipid-lowering therapy early after transplantation. We performed a retrospective analysis of all patients who underwent allogeneic HSCT at the Dana-Farber Cancer Institute from 1998 to 2008 and who survived more than 100 days. The incidence of hypercholesterolemia and hypertriglyceridemia in the first 2 years after transplantation was 73.4% and 72.5%, respectively. In multivariable analysis, the development of acute graft-versus-host disease was independently associated with both hypercholesterolemia (odds ratio [OR] = 1.62) and hypertriglyceridemia (OR = 1.54) after transplantation. Statin use was instituted in 29% of patients and was associated with a significant net reduction in total cholesterol (65 mg/dL, P < .0001), triglyceride (118 mg/dL P < .0001), and LDL levels (59 mg/dL P < .0001) without any significant adverse effects. These data suggest that hyperlipidemia is common in the first 2 years after allogeneic transplantation when most patients remain under the care of the transplantation physician and lipid-lowering therapy may be underutilized. Given the cardiovascular risk associated with hyperlipidemia and the tolerability of statins, further prospective evaluation of lipid abnormalities and their treatment seems well warranted.

Abstract
Advances in transplantation techniques and supportive care strategies have resulted in a significant improvement in survival of those who have undergone treatment. However, hematopoietic stem cell transplantation (HSCT) survivors are at risk of developing long-term complications, such as endocrinopathies, musculoskeletal disorders, cardiopulmonary compromise and subsequent malignancies. These complications have a direct impact on the morbidity and mortality experienced by HSCT survivors. Two-thirds of HSCT survivors develop at least one chronic health condition; while a fifth develop severe or life-threatening conditions. HSCT patients who have survived for at least 5 years post-transplantation are at a fourfold to ninefold increased risk of late mortality for as long as 30 years from HSCT, producing an estimated 30% lower life expectancy compared with the general population. The high burden of morbidity experienced by HSCT survivors makes it critically important that there is standardized follow-up of HSCT survivors at high risk for post-HSCT complications. The Center for International Blood and Marrow Transplant Research/European Group for Blood and Marrow Transplantation/American Society for Blood and Marrow Transplantation and the Children's Oncology Group long-term follow-up guidelines offer such standardized care. Future steps include wider dissemination and refinement of these guidelines.

Abstract
We conducted a matched-cohort analysis of autologous transplant conditioning regimens for diffuse large cell lymphoma in 92 patients treated with either radioimmunotherapy (RIT) or total body irradiation (TBI)-based conditioning regimens. The RIT regimen consisted of 0.4 mCi/kg of (90)Y-ibritumomab tiuxetan plus BEAM (BCNU, etoposide, cytarabine, melphalan). The TBI-based regimen combined fractionated TBI at 1200 cGy, with etoposide and cyclophosphamide. Five factors were matched between 46 patient pairs: age at transplant ±5 years, disease status at salvage, number of prior regimens, year of diagnosis ±5 years, and year of transplantation ±5 years. Patients in the TBI group had higher rates of cardiac toxicity and mucositis, whereas Z-BEAM patients had a higher incidence of pulmonary toxicity. Overall survival at 4 years was 81.0% for the Z-BEAM and 52.7% for the TBI group (P = .01). The 4-year cumulative incidence of relapse/progression was 40.4% and 42.1% for Z-BEAM and TBI, respectively (P = .63). Nonrelapse mortality was superior in the Z-BEAM group: 0% compared with 15.8% for TBI at 4 years (P < .01). Our data demonstrate that RIT-based conditioning had a similar relapse incidence to TBI, with lower toxicity, resulting in improved overall survival, particularly in patients with ≥2 prior regimens.

Abstract
HSCT is being increasingly offered as a curative option for children with hematologic malignancies. Although survival has improved, the long-term morbidity ascribed to the HSCT procedure is not known. We compared the risk of chronic health conditions and adverse health among children with cancer treated with HSCT with survivors treated conventionally, as well as with sibling controls. HSCT survivors were drawn from BMTSS (N = 145), whereas conventionally treated survivors (N = 7207) and siblings (N = 4020) were drawn from CCSS. Self-reported chronic conditions were graded with CTCAEv3.0. Fifty-nine percent of HSCT survivors reported ≥ 2 conditions, and 25.5% reported severe/life-threatening conditions. HSCT survivors were more likely than sibling controls to have severe/life-threatening (relative risk [RR] = 8.1, P < .01) and 2 or more (RR = 5.7, P < .01) conditions, as well as functional impairment (RR = 7.7, P < .01) and activity limitation (RR = 6.3, P < .01). More importantly, compared with CCSS survivors, BMTSS survivors demonstrated significantly elevated risks (severe/life-threatening conditions: RR = 3.9, P < .01; multiple conditions: RR = 2.6, P < .01; functional impairment: RR = 3.5, P < .01; activity limitation: RR = 5.8, P < .01). Unrelated donor HSCT recipients were at greatest risk. Childhood HSCT survivors carry a significantly greater burden of morbidity not only compared with noncancer populations but also compared with conventionally treated cancer patients, providing evidence for close monitoring of this high-risk population.

Abstract
Although important advances have been made in curing childhood cancer in the last several decades, long-term survivors face considerable morbidity and mortality because of late effects from their initial anticancer therapy. By 30 years after treatment, the cumulative mortality from treatment-related medical illness actually exceeds that of mortality from cancer recurrence. Cardiovascular disease, in particular, is a leading threat to the well-being of adult survivors of childhood cancers. Unfortunately, the mechanisms of these late cardiac effects are understudied and poorly understood. This article reviews cardiotoxicity associated with 2 major anticancer regimens used in treating childhood cancer patients: anthracycline treatment and radiation therapy. The known pathophysiology and clinical cardiac risk factors that further predispose these patients to late-onset cardiac events are discussed. Basic and translational research is urgently needed to clarify pathophysiologic mechanisms of late cardiac effects and to develop therapies to improve both long-term survival and quality of life of adults cured of pediatric cancers.

Abstract
Hematopoietic SCT (HSCT) is a life-saving therapy in children, but has been associated with heart failure. Little is known about subclinical changes in cardiac function. We examined changes in systolic and diastolic function from pre- to 1-year post HSCT by echocardiography. All patients (n=74, 61% men, median age 9.1 years, mean left-ventricular (LV) ejection fraction 61.3±4.9%) who underwent HSCT at Children's Hospital Boston between 2005 and 2008, were <21 years at time of HSCT, and had routine pre- and 1-year post echocardiograms were included. Systolic function parameters, including LV ejection fraction, rate-corrected velocity of fiber shortening (Vcfc) and stress-velocity index and diastolic parameters, including tissue Doppler imaging (TDI)-derived velocities, and left-ventricular flow propagation, were compared before and after transplant. At 1-year post HSCT, systolic function, as measured by Vcfc (1.10±0.15 vs 1.04±0.12 circ/s; P=0.03) and stress-velocity index (z-score 0.40±1.4 vs -0.20±1.1; P=0.02), had worsened; diastolic function parameters, including mitral E' velocity (16.6±3.9 vs 15.0±3.4 cm/s; P=0.01) and tricuspid E' velocity (14.3±3.6 vs 12.4±2.8 cm/s; P=0.002) had also decreased. At 1-year post HSCT, children have subclinical declines in systolic and diastolic function. These small changes might become clinically important over time. Serial non-invasive assessment of cardiac function should be considered in all children following HSCT.

Abstract
More than 25,000 allogeneic hematopoietic stem cell transplantations (allo-HCTs) are expected to be performed worldwide in 2010, a number that has been increasing yearly. With broadening indications, more options for allo-HCT, and improvement in survival, by 2020 there may be up to half a million long-term survivors after allo-HCT worldwide. These patients have increased risks for various late complications, which can cause morbidity and mortality. Most long-term survivors return to the care of their local hematologists/oncologists or primary care physicians, who may not be familiar with specialized monitoring recommendations for this patient population. The purpose of this article is to describe practical approaches to screening for and managing these late effects, with the goal of reducing preventable morbidity and mortality associated with allo-HCT.

Abstract
The cancer patient with coronary disease presents particular challenges that directly impact on the management of coronary disease, both stable and acute. The frequent need for surgery in the cancer patient is an important consideration in avoiding a coronary artery stent or any percutaneous coronary intervention for management of chronic stable angina, which will delay surgery or pose of risk of stent thrombosis during surgery. Cancer surgery is considered low or intermediate cardiac risk so revascularization before surgery is needed only in exceptional circumstances. Medical treatment in most patients or coronary artery bypass graft in high risk situations may be preferable if the cancer is being actively treated. The likelihood of thrombocytopenia, either primary from bone marrow disease, or secondarily during chemotherapy causes concern about the need for continuous use of platelet suppressing agents, aspirin for all patients, or double antiplatelet therapy in all patients after receiving a coronary artery stent. Drug-eluting stents pose special problems and should be avoided. Even bare metal stents may have a higher long-term risk of stent thrombosis in the cancer patient. The increase in propensity for venous clotting, either as a result of the cancer itself, or especially with selected chemotherapeutic agents may be an issue after stenting and certainly early after coronary bypass surgery. Aggressive medical treatment to reduce risk factors, especially with statins is essential to stabilize the underlying coronary disease.
