Late effects of blood and marrow transplantation

Driving Distance and Patient-Reported Outcomes in Hematopoietic Cell Transplantation Survivors

Long driving distances to transplantation centers may impede access to care for hematopoietic cell transplantation (HCT) survivors. As a secondary analysis from the multicenter INSPIRE study (NCT01602211), we examined baseline data from relapse-free HCT adult survivors (2 to 10 years after allogeneic or autologous HCT) to investigate the association between driving distances and patient-reported outcome (PRO) measures of distress and physical function. We analyzed predictors of elevated distress and impaired physical function using logistic regression models that operationalized driving distance first as a continuous variable and separately as a dichotomous variable (<100 versus 100+ miles). Of 1136 patients available for analysis from 6 US centers, median driving distance was 82 miles and 44% resided 100+ miles away from their HCT centers. Elevated distress was reported by 32% of patients, impaired physical function by 19%, and both by 12%. Driving distance, whether operationalized as a continuous or dichotomous variable, had no impact on distress or physical function in linear regression modeling (95% confidence interval, 1.00 to 1.00, for both PROs with driving distance as a continuous variable). In contrast, chronic graft-versus-host-disease, lower income, and lack of Internet access independently predicted both elevated distress and impaired physical function. In summary, we found no impact of driving distance on distress and physical function among HCT survivors. Our results have implications for how long-term follow-up care is delivered after HCT, with regard to the negligible impact of driving distances on PROs and also the risk of a "digital divide" worsening outcomes among HCT survivors without Internet access.

Lessons learned from a pilot randomized clinical trial of home-based exercise prescription before allogeneic hematopoietic cell transplantation

Allogeneic hematopoietic cell transplantation (alloHCT) is a life-saving technology that can cure otherwise incurable diseases, but imposes significant physiologic stress upon recipients. This stress leads to short-term toxicity and mid- to long-term physical function impairment in some recipients. Exercise interventions have demonstrated preliminary efficacy in preserving physical function in HCT recipients, but the role of these interventions prior to HCT (prehabilitative) is less known. We tested a 5- to 12-week, prehabilitative higher intensity home-based aerobic exercise intervention in a randomized study of alloHCT candidates. Of 113 patients screened, 34 were randomized to control or intervention groups, 16 underwent pre- and post-intervention peak oxygen consumption (VO2peak) testing, and 12 underwent pre- and post-intervention 6-min walk distance (6MWD) testing. No significant differences in VO2peak or 6MWD were seen pre- to post-intervention between intervention and control groups, but final numbers of evaluable participants in each group were too small to draw inferences regarding the efficacy of the intervention. We conclude that the design of our prehabilitative intervention was not feasible in this pilot randomized study, and make recommendations regarding the design of future exercise intervention studies in alloHCT.

Body composition after allogeneic haematopoietic cell transplantation/total body irradiation in children and young people: a restricted systematic review

PURPOSE

To collate evidence of changes in body composition following treatment of leukaemia in children, teenagers and young adults (CTYA, 0-24 years) with allogeneic haematopoietic stem cell transplant and total body irradiation (HSCT+TBI).

METHODS

Papers were identified by searching Medline and Google Scholar, reference lists/citations and contacting key authors, with no date or language restrictions. Inclusion criteria were as follows: leukaemia, HSCT+TBI, aged ≤ 24 years at HSCT and changes in body composition (total fat, central adiposity, adipose tissue function, muscle mass, muscle function). Quality was assessed using a brief Newcastle-Ottawa scale.

RESULTS

Of 900 papers, 20 were included: seven controlled, five uncontrolled studies and eight case reports. Study quality appeared good. There was little evidence of differences in total fat/weight for HSCT + TBI groups (compared to healthy controls/population norms/short stature controls). There was some evidence of significantly higher central adiposity and differences in adipose tissue function (compared to leukaemic/non-leukaemic controls). Muscle mass was significantly lower (compared to healthy/obese controls). Muscle function results were inconclusive but suggested impairment. Case reports confirmed a lipodystrophic phenotype.

CONCLUSIONS

Early remodelling of adipose tissue and loss of skeletal muscle are evident following HSCT + TBI for CTYA leukaemia, with extreme phenotype of overt lipodystrophy. There is some evidence for reduced muscle effectiveness.

IMPLICATIONS FOR CANCER SURVIVORS

Body composition changes in patients after HSCT + TBI are apparent by early adult life and link with the risk of excess cardiometabolic morbidity seen in adult survivors. Interventions to improve muscle and/or adipose function, perhaps utilizing nutritional manipulation and/or targeted activity, should be investigated.

Long-term Follow-up of Hematopoietic Stem Cell Transplant Survivors: A Focus on Screening, Monitoring, and Therapeutics

Annually, ~50,000 patients undergo hematopoietic stem cell transplantation (HCT) worldwide with almost 22,000 of these patients receiving HCT in the United States. HCT is a curative option for a wide range of hematologic malignancies, and advances in transplantation medicine have resulted in an increase in HCT survivors. It is anticipated that the number of HCT survivors will more than double from 242,000 in 2020 to ~500,000 in 2030. Survivors of HCT are at an increased risk of developing late complications due to exposure to chemotherapy and/or radiation in the pre-, peri-, and post-HCT phases and these cumulative exposures have the potential to damage normal tissue. This tissue damage leads to the early onset of chronic health conditions resulting in premature mortality in HCT survivors, who have a 15-year cumulative incidence of severe or life-threatening chronic health conditions exceeding 40%. Due to the significant burden of morbidity in HCT survivors and the delay in the development of long-term complications, this delicate patient population requires life-long monitoring due to the risk for neuropsychological, cardiac, pulmonary, renal, hepatic, ocular, skeletal, cardiac, endocrine, fertility, and sexual health complications, as well as secondary neoplasms. This review will focus on recent advances in screening, monitoring, and therapeutics for late-occurring or long-term complications in HCT survivors.

Allogeneic reactivity-mediated endothelial cell complications after HSCT: a plea for consensual definitions

Endothelial cell (EC) activation has been suspected of triggering a group of rare and dismal complications that can occur after allogeneic hematopoietic stem cell transplantation (HSCT). Capillary leak syndrome, engraftment syndrome, transplant-associated microangiopathy, diffuse alveolar hemorrhage, and idiopathic pneumonia syndrome are the main nosological entities. Post-HSCT endotheliitis can be triggered by chemotherapy, infections, and calcineurin inhibitors, but allogeneic reactivity is claimed to be the common denominator. Endothelial damages are thought to activate several deleterious pathways (proapoptotic, procoagulant, proinflammatory) and can lead to multiorgan failure; however, clinical manifestations of each syndrome overlap, and their relationship with graft-versus-host disease could be minimal. The lack of well-defined diagnostic criteria does not allow for a clear-cut comparison in the current literature. Therapeutic efforts have been made to intercept the pathogenic mechanisms leading to EC dysfunction, but remission rates and survival remain mostly unsatisfactory. In this article, we have reviewed the incidence, clinical features, and treatment approaches of EC activation syndromes, and we plead for the development of internationally accepted standard definitions.

Thyroid dysfunctions in adult patients after allogeneic hematopoietic stem cell transplantation

INTRODUCTION

Thyroid dysfunction (TD) is one of the major endocrinopathies shown after allogeneic hematopoietic stem cell transplantation over the long term. The incidence and the risk factors for TD have varied widely.

PATIENTS AND METHODS

Two hundred and fifty-nine patients with pre-transplant normal thyroid function tests who survived at least 1 year after allo-HSCT between 2006-2016 were included in the study.

RESULTS

Sixty-four patients (25%) developed TD at median of 34 months (range, 1-112 months). Hypothyroidism was detected in 32 patients (12%): 5 patients had primary hypothyroidism, and subclinical hypothyroidism occurred in 27 patients. 18 patients (7%) were diagnosed with hyperthyroidism: 2 patients (0.07%) were treated for primary hyperthyroidism, and 16 patients (6%) were followed for subclinical hyperthyroidism. Euthyroid sick syndrome occurred in 14 cases. None of the patients with thyroid dysfunction developed secondary thyroid malignancy. Receiving high-dose TBI (P = .001) was found to be significant risk for hypothyroidism; older age than median (P = .01) and pre-transplant active disease (P < .0001) were related to hyperthyroidism.

CONCLUSIONS

Thyroid dysfunction, mostly hypothyroidism, is a long-term complication after allo-HSCT in 25% of patients. Older age, pre-transplant active disease, and receiving TBI are among the risk factors. Sustained long-term monitoring of thyroid function test should be considered post allo-HSCT.

Iron and Chelation in Biochemistry and Medicine: New Approaches to Controlling Iron Metabolism and Treating Related Diseases

Iron is essential for all living organisms. Many iron-containing proteins and metabolic pathways play a key role in almost all cellular and physiological functions. The diversity of the activity and function of iron and its associated pathologies is based on bond formation with adjacent ligands and the overall structure of the iron complex in proteins or with other biomolecules. The control of the metabolic pathways of iron absorption, utilization, recycling and excretion by iron-containing proteins ensures normal biologic and physiological activity. Abnormalities in iron-containing proteins, iron metabolic pathways and also other associated processes can lead to an array of diseases. These include iron deficiency, which affects more than a quarter of the world's population; hemoglobinopathies, which are the most common of the genetic disorders and idiopathic hemochromatosis. Iron is the most common catalyst of free radical production and oxidative stress which are implicated in tissue damage in most pathologic conditions, cancer initiation and progression, neurodegeneration and many other diseases. The interaction of iron and iron-containing proteins with dietary and xenobiotic molecules, including drugs, may affect iron metabolic and disease processes. Deferiprone, deferoxamine, deferasirox and other chelating drugs can offer therapeutic solutions for most diseases associated with iron metabolism including iron overload and deficiency, neurodegeneration and cancer, the detoxification of xenobiotic metals and most diseases associated with free radical pathology.

Defibrotide inhibits donor leucocyte-endothelial interactions and protects against acute graft-versus-host disease

Allogeneic hematopoietic stem cell transplantation (allo‐HCT) is an effective therapy for the treatment of high‐risk haematological malignant disorders and other life‐threatening haematological and genetic diseases. Acute graft‐versus‐host disease (aGvHD) remains the most frequent cause of non‐relapse mortality following allo‐HCT and limits its extensive clinical application. Current pharmacologic agents used for prophylaxis and treatment of aGvHD are not uniformly successful and have serious secondary side effects. Therefore, more effective and safe prophylaxis and therapy for aGvHD are an unmet clinical need. Defibrotide is a multi‐target drug successfully employed for prophylaxis and treatment of veno‐occlusive disease/sinusoidal obstruction syndrome. Recent preliminary clinical data have suggested some efficacy of defibrotide in the prevention of aGvHD after allo‐HCT. Using a fully MHC‐mismatched murine model of allo‐HCT, we report here that defibrotide, either in prophylaxis or treatment, is effective in preventing T cell and neutrophil infiltration and aGvHD‐associated tissue injury, thus reducing aGvHD incidence and severity, with significantly improved survival after allo‐HCT. Moreover, we performed in vitro mechanistic studies using human cells revealing that defibrotide inhibits leucocyte‐endothelial interactions by down‐regulating expression of key endothelial adhesion molecules involved in leucocyte trafficking. Together, these findings provide evidence that defibrotide may represent an effective and safe clinical alternative for both prophylaxis and treatment of aGvHD after allo‐HCT, paving the way for new therapeutic approaches.

Optimal Delivery of Follow-Up Care After Allogeneic Hematopoietic Stem-Cell Transplant: Improving Patient Outcomes with a Multidisciplinary Approach

The increasing indications for allogeneic stem-cell transplant in patients with hematologic malignancies and non-malignant diseases combined with improved clinical outcomes have contributed to increase the number of long-term survivors. However, survivors are at increased risk of developing a unique set of complications and late effects, besides graft-versus-host disease and disease relapse. In this setting, the management capacity of a single health-care provider can easily be overwhelmed. Thus, to provide appropriate survivorship care, a multidisciplinary approach for the long-term follow-up is essential. This review aims at summarizing the most relevant information that a health-care provider should know to establish a follow-up care plan, in the light of individual exposures and risk factors, that includes all organ systems and considers the psychological burden of these patients.

Fear of disease progression and relevant correlates in acute leukemia patients prior to allogeneic hematopoietic stem cell transplantation

OBJECTIVE

Prior to hematopoietic stem cell transplantation (HSCT), and despite the high objective risks associated with HSCT, fear of progression (FoP) has only sparsely been studied in patients with acute leukemia until now. The aim of this study was the assessment of the prevalence of FoP, and any relevant correlates and typical concerns.

METHODS

We included 59 adult patients with acute leukemia who were tested prior to their first HSCT during an in-patient stay. Patients completed self-report measures assessing FoP (Fear of Progression Questionnaire-Short Form, FoP-Q-SF) and relevant correlates of FoP (eg, patients' physical state, depression, psychosocial distress, or social support).

RESULTS

About one third of the patients (35.6%; n = 21) had high FoP. Higher FoP was associated with previous cancer diagnosis, as well as depression, anxiety, reduced physical functioning, lower mental health-related quality of life, and lower positive social support. The greatest fears reported by these patients reflected common fears of cancer patients (eg, fear about leaving their families behind), but also specific fears related to the current situation (eg, fear of severe medical treatments during the course of the illness).

CONCLUSIONS

This was the first study providing an extensive analysis of FoP in leukemia patients prior to the extreme situation of HSCT. FoP is frequent and of major clinical importance for these patients. Hence, we recommend that patients undergo routine screening for FoP, to identify highly distressed patients at an early stage, and to offer targeted support.

Predictors of Loss to Follow-Up Among Pediatric and Adult Hematopoietic Cell Transplantation Survivors: A Report from the Center for International Blood and Marrow Transplant Research

Follow-up is integral for hematopoietic cell transplantation (HCT) care to ensure surveillance and intervention for complications. We characterized the incidence of and predictors for being lost to follow-up. Two-year survivors of first allogeneic HCT (10,367 adults and 3865 children) or autologous HCT (7291 adults and 467 children) for malignant/nonmalignant disorders between 2002 and 2013 reported to the Center for International Blood and Marrow Transplant Research were selected. The cumulative incidence of being lost to follow-up (defined as having missed 2 consecutive follow-up reporting periods) was calculated. Marginal Cox models (adjusted for center effect) were fit to evaluate predictors. The 10-year cumulative incidence of being lost to follow-up was 13% (95% confidence interval [CI], 12% to 14%) in adult allogeneic HCT survivors, 15% (95% CI, 14% to 16%) in adult autologous HCT survivors, 25% (95% CI, 24% to 27%) in pediatric allogeneic HCT survivors, and 24% (95% CI, 20% to 29%) in pediatric autologous HCT survivors. Factors associated with being lost to follow-up include younger age, nonmalignant disease, public/no insurance (reference: private), residence farther from the tranplantation center, and being unmarried in adult allogeneic HCT survivors; older age and testicular/germ cell tumor (reference: non-Hodgkin lymphoma) in adult autologous HCT survivors; older age, public/no insurance (reference: private), and nonmalignant disease in pediatric allogeneic HCT survivors; and older age in pediatric autologous HCT survivors. Follow-up focusing on minimizing attrition in high-risk groups is needed to ensure surveillance for late effects.

Pathogenicity of BK virus on the urinary system

Introduction

The polyomaviruses are omnipresent in nature. The major sites of BK virus appearance are the kidney tubular epithelial cells and urinary bladder surface transitional cells.

Material and methods

A literature search according to PRISMA guidelines within the Medline database was conducted in July 2019 for articles presenting data about BK virus in urologic aspect without setting time limits, using the terms ‘BK virus’ in conjunction with transplantation, nephropathy, stenosis, cancer, bladder, prostate, kidney.

Results

The BK virus usually stays latent, however, its replication may become active in various clinical situations of impaired immunocompetence such as solid organ transplantation, bone marrow transplantation, AIDS, pregnancy, multiple sclerosis, administration of chemotherapy or biologic therapy. BK virus is associated with two main complications after transplantation: polyomavirus-associated nephropathy in kidney transplant patients and polyomavirus-associated hemorrhagic cystitis in allogeneic hematopoietic stem cell transplant patients.

Conclusions

The aim of this article was to present available data on urologic aspects of BK virus infection, its detection methods and available treatment.

Expanding Access to Lung Cancer Clinical Trials by Reducing the Use of Restrictive Exclusion Criteria: Perspectives of a Multistakeholder Working Group

Low rates of adult patient participation have been a persistent problem in cancer clinical trials and have continued to be a barrier to efficient drug development. The routine use of significant exclusion criteria has contributed to this problem by limiting participation in studies and creating significant clinical differences between the study cohorts and the real-world cancer patient populations. These routine exclusions also unnecessarily restrict opportunities for many patients to access potentially promising new therapies during clinical development. Multiple efforts are underway to broaden eligibility criteria, allowing more patients to enroll in studies and generating more robust data regarding the effect of novel therapies in the population at large. Focusing specifically on lung cancer as an example, a multistakeholder working group empaneled by the LUNGevity Foundation identified 14 restrictive and potentially outdated exclusion criteria that appear frequently in lung cancer clinical trials. As a part of the project, the group evaluated data from multiple recent lung cancer studies to ascertain the extent to which these 14 criteria appeared in study protocols and played a role in excluding patients (screen failures). The present report describes the working group's efforts to limit the use of these routine exclusions and presents clinical justifications for reducing the use of 14 criteria as routine exclusions in lung cancer studies, potentially expanding trial eligibility and improving the generalizability of the results from lung cancer trials.

Liver disease during and after hematopoietic stem cell transplantation in adults: a single-center Egyptian experience

BACKGROUND

Hepatic complications are a well-known cause of both early and late mortality and morbidity in hematopoietic stem cell transplant (HSCT) recipients. Early diagnosis and management of hepatic complications is important in order to commence appropriate therapy. Conditioning regimens, acute and chronic graft versus host disease, sinusoidal obstruction syndrome, and infections among others represent major hepatic complications for the transplant recipient. We assessed liver function tests, viral markers, polymerase chain reaction, abdominal ultrasound, portal, and hepatic venous duplex in 88 patients underwent autologous and 102 patients underwent allogeneic transplant as well as liver biopsy in selected patients in this retrospective study and evaluated early and late hepatic complications and their impact on transplant outcome.

RESULTS

The major cause of hepatic injury in allogeneic patients is the conditioning regimen (38.8%) followed by acute GVHD (14.7%), after day +100 chronic hepatic GVHD is the primary cause of liver injury which occurred in about 40% of allogeneic patients. In autologous patients, the first cause of hepatotoxicity is also conditioning regimen involving 27.9% of patients followed by flare of viral hepatitis in 7.9% and sepsis in 6.3% of cases. The prevalence of HCV, HBV, and CMV is 19%, 16%, and 8%, respectively.

CONCLUSION

In our study, conditioning regimens, acute and chronic hepatic GVHD are frequent causes of hepatic injury following allogeneic HSCT while conditioning regimens, flare of viral hepatitis, and sepsis represent the most common causes of hepatic injury following autologous HSCT.

Improving Quality of Life in Hematopoietic Stem Cell Transplantation Survivors Through a Positive Psychology Intervention

Despite advances in transplantation medicine, psychological distress and quality of life and functional deficits continue to compromise survivorship after hematopoietic stem cell transplantation (HSCT). With increasing numbers of HSCT survivors, supportive oncology interventions that target health-related outcomes in HSCT survivorship are needed. Here we aimed to test the feasibility and acceptability of a group format phone-delivered positive psychology (PP) intervention in HSCT survivors. This is a one-arm pilot study design that adapted and tested an individual PP intervention used in cardiac disease to a phone-delivered group-based program for HSCT survivors who were .4 to 39 years post-transplantation. All participants received an 8-session weekly PP intervention. We assessed feasibility by the enrollment and intervention completion rates. We examined acceptability on a 10-point Likert scale of ease and utility. Unstructured qualitative interviews were used to obtain participant feedback on the intervention for future application in a larger trial. Self-reported assessments on psychological, functional, and quality of life outcomes were administered at baseline and at follow-up (the end of the intervention). Of 64 eligible participants, 29 (45%) enrolled in the study. For the main aim of intervention feasibility and acceptability, participants completed 96% of all PP sessions and rated the ease (7.6 ± 1.7) and utility (8.1 ± 1.1) of sessions highly. Of the self-reported assessments obtained, the PP intervention resulted in improvements in the resilience scale (mean difference, 2.4 ± 5.4; P = .03). From unstructured qualitative interviews, participants reported the PP exercises and intervention helped them to focus on positive emotions and the group format fostered a sense of community and social support. An 8-week phone-delivered group format PP intervention is feasible and acceptable in HSCT survivors. The piloted intervention could be tested with minor modifications in a randomized study to definitively examine the impact of the group format PP intervention on health-related outcomes.

Permanent Impairment-Free, Relapse-Free Survival: A Novel Composite Endpoint to Evaluate Long-Term Success in Allogeneic Transplantation

Permanent impairment (PI) of vital organs is one of the transplantation-related health problems affecting the quality of life and morbidity even in patients who do not develop graft-versus-host disease (GVHD) after allogeneic hematopoietic stem cell transplantation (allo-HCT), but no data are available on PI of multiple organs. This retrospective study aimed to estimate a novel composite endpoint of PI-free, relapse-free survival (PIRFS) in 164 allo-HCT recipients. We defined PI as >26% to 30% impairment of the whole person in 6 vital organs using the whole person impairment rating. Conventional GVHD-free/relapse-free survival (GRFS) and PIRFS at 5 years were 33.8% (95% confidence interval [CI], 26.5% to 41.3%) and 40.6% (95% CI, 32.6% to 48.4%), respectively. In the whole cohort, PIRFS was higher than GRFS at any time after allo-HCT. However, PIRFS was lower than GRFS after day 397 post-transplantation in patients who underwent umbilical cord blood transplantation (UCBT). In UCBT recipients, 5-year GRFS and PIRFS were 47.6% (95% CI, 34.3% to 59.7%) and 39.2% (95% CI, 26.6% to 51.5%), respectively. The cumulative incidence of PI after 5 years was 20.9% (95% CI, 13.7% to 29.0%) in patients surviving for ≥6 months without relapse. The multivariate analysis revealed that high disease risk (hazard ratio [HR], 1.91; 95% CI, 1.26 to 2.88; P < .01) and Karnofsky Performance Status score ≤90% at transplantation (HR, 1.73; 95% CI, 1.14 to 2.63; P = .01) were correlated with the lower PIRFS, whereas UCBT (HR, 2.35; 95% CI, 1.11 to 4.99; P = .03), grade III-IV acute GVHD by day 180 (HR, 3.59; 95% CI, 1.04 to 12.4; P = .04), and thrombotic microangiopathy by day 180 (HR, 2.74; 95% CI, 1.10 to 6.87; P = .03) were significantly correlated with a higher incidence of PI. More than 20% of long-term survivors had PI. Our data suggest that PIRFS is a useful endpoint for assessing long-term transplantation success from a different perspective than has been established previously.

Patient-Reported Neuropsychiatric Outcomes of Long-Term Survivors after Chimeric Antigen Receptor T Cell Therapy

CD19-targeted chimeric antigen receptor (CAR) modified T cell immunotherapy is a novel treatment with promising results in patients with relapsed/refractory lymphoid malignancies. CAR T cell therapy has known early toxicities of cytokine release syndrome and neurotoxicity, but little is known about long-term neuropsychiatric adverse effects. We have used patient-reported outcomes, including Patient-Reported Outcomes Measurement Information System (PROMIS) measures, to assess neuropsychiatric and other patient-reported outcomes of 40 patients with relapse/refractory chronic lymphocytic leukemia, non-Hodgkin lymphoma, and acute lymphoblastic leukemia 1 to 5 years after treatment with CD19-targeted CAR T cells. Mean T scores of PROMIS domains of global mental health, global physical health, social function, anxiety, depression, fatigue, pain, and sleep disturbance were not clinically meaningfully different from the mean in the general US population. However, 19 patients (47.5%) reported at least 1 cognitive difficulty and/or clinically meaningful depression and/or anxiety, and 7 patients (17.5%) scored ≤40 in global mental health, indicating at least 1 standard deviation worse than the general population mean. Younger age was associated with worse long-term global mental health (P = .02), anxiety (P = .001), and depression (P= .01). Anxiety before CAR T cell therapy was associated with increased likelihood of anxiety after CAR T cell therapy (P = .001). Fifteen patients (37.5%) reported cognitive difficulties after CAR T cell therapy. Depression before CAR T cell therapy was statistically significantly associated with higher likelihood of self-reported post-CAR T cognitive difficulties (P = .02), and there was a trend for an association between acute neurotoxicity and self-reported post-CAR T cognitive difficulties (P = .08). Having more post-CAR T cognitive difficulties was associated with worse global mental health and global physical health. Our study demonstrates overall good neuropsychiatric outcomes in 40 long-term survivors after CAR T cell therapy. However, nearly 50% of patients in the cohort reported at least 1 clinically meaningful negative neuropsychiatric outcome (anxiety, depression, or cognitive difficulty), indicating that a significant number of patients would likely benefit from mental health services following CAR T cell therapy. Younger age, pre-CAR T anxiety or depression, and acute neurotoxicity may be risk factors for long-term neuropsychiatric problems in this patient population. Larger studies are needed to confirm these findings.

Evaluation of Second Solid Cancers After Hematopoietic Stem Cell Transplantation in European Patients

Importance

Incidence and risk factors of second solid cancers (SSCs) that occur after hematopoietic stem cell transplantation (HSCT) are well documented. However, clinical outcome data of patients who developed an SSC after HSCT are limited.

Objective

To assess the outcome of patients with an SSC occurring after HSCT from the time of SSC diagnosis.

Design, Setting, and Participants

This cohort study used data of 4065 patients from 26 countries registered with the European Society for Blood and Marrow Transplantation, which has maintained clinical data since 1977 of patients who received a transplant. Information from all patients who underwent a transplant in Europe and had an SSC diagnosis between January 1, 2000, and December 31, 2014, was extracted. The cohort included patients with 18 different cancers. Data analysis was conducted from September 3, 2017, to March 17, 2018.

Main Outcomes and Measures

Median and 5-year age-standardized overall survival, causes of death, risk factor multivariate analysis using a clustered Cox proportional hazard regression model, and standardized mortality ratio were calculated for each of the 18 types of SSC.

Results

In total, 220 617 patients underwent a transplant, of whom only 4065 (1.8%) patients with a second solid cancer after HSCT were included in the study. Among the 4065 patients, 2321 (57.1%) were men and 1744 (42.9%) were women, with a mean (range) age of 59.1 (3.2-82.3) years at diagnosis of second solid cancer. The 5-year age-standardized overall survival was 47% (95% CI, 45%-49%). The 5-year overall survival rate after SSC diagnosis was poor for pancreas, lung, hepatobiliary, esophageal, brain, and gastric cancers, with a median survival between 0.6 and 1 year. The 5-year overall survival was intermediate for endometrial, colorectal, sarcomas, ovarian, bladder, oropharyngeal, and kidney cancers, with a median survival between 2 and 10 years. The 5-year overall survival was more favorable for melanoma, breast, prostate, cervix, and thyroid cancers, with a median survival of 10 or more years. Additional transplant-associated factors for mortality for patients treated with allogeneic HSCT were age at transplant, donor type, conditioning regimen, and graft-vs-host disease. In total, 1777 patients (43.7%) died, of which 1256 (74.8%) were from SSC, 344 (20.5%) from primary disease, and 79 (4.7%) from other causes. Standardized mortality ratio was higher, compared with de novo solid cancers, for melanoma, prostate, breast, kidney, bladder, colorectal, and endometrial cancers but not for the other cancers.

Conclusions and Relevance

The outcome of SSC is mainly dependent on the type of second cancer; thus, future studies should investigate the reasons the standardized mortality ratio is higher for some cancers to identify whether patients with these cancers should be treated differently and to help in screening and counseling patients who developed an SSC after HSCT.

HBV Reactivation in Patients Undergoing Hematopoietic Stem Cell Transplantation: A Narrative Review

HBV reactivation (HBVr) can occur due to the ability of HBV to remain latent in the liver as covalently closed circular DNA and by the capacity of HBV to alter the immune system of the infected individuals. HBVr can occur in patients undergoing hematopoietic stem cell transplantation (HSCT) with a clinical spectrum that ranges from asymptomatic infection to fulminant hepatic failure. The risk of HBVr is determined by a complex interplay between host immunity, virus factors, and immunosuppression related to HSCT. All individuals who undergo HSCT should be screened for HBV. HSCT patients positive for HBsAg and also those HBcAb-positive/HBsAg-negative are at high risk of HBV reactivation (HBVr) due to profound and prolonged immunosuppression. Antiviral prophylaxis prevents HBVr, decreases HBVr-related morbidity and mortality in patients with chronic or previous HBV. The optimal duration of antiviral prophylaxis remains to be elucidated. The vaccination of HBV-naïve recipients and their donors against HBV prior to HSCT has an important role in the prevention of acquired HBV infection. This narrative review provides a comprehensive update on the current concepts, risk factors, molecular mechanisms, prevention, and management of HBVr in HSCT.

Endocrine Challenges and Metabolic Profile in Recipients of Allogeneic Haematopoietic Stem Cell Transplant: A Cross-Sectional Study from Southern India

Although haematopoietic stem cell transplant has been successfully employed in the cure of several malignant and non-malignant conditions, survivors often suffer from delayed effects involving the endocrine system and cardio-metabolic risk factors. In this cross-sectional study, we aimed to assess the prevalence of endocrine dysfunction and alterations in metabolic profile in 63 recipients of allogeneic stem cell transplantation as compared to 65 age, sex and body mass index matched controls. Hypogonadism emerged as the most prevalent endocrinopathy, present in 23/60 (38.3%) of subjects, followed by overt and subclinical hypothyroidism in 10/63 (15.9%) of cases. The metabolic parameters, that included plasma glucose and lipid profile were not significantly different between cases and controls. However, insulin resistance, as assessed by surrogate markers employing HOMA IR (3.82 vs. 1.97) and QUICKI (0.338 vs. 0.373) was significantly higher among cases than in controls (P < 0.05). Abnormal glucose tolerance was observed in about one-third of the study cohort. The prevalence of overt diabetes (7%) was similar to that in the general population across India (8%); the prevalence of pre-diabetes (21%) was however considerably higher than the national average of 10%. Thus, although the process of haematopoietic stem cell transplant is often curative for the primary haematological disease, it may be associated with various delayed effects on the endocrine system and metabolic profile. Therefore, it is imperative that recipients be screened for the potential development of these late effects subsequent to the transplantation procedure.

Current Practice in Vitamin D Management in Allogeneic Hematopoietic Stem Cell Transplantation: A Survey by the Transplant Complications Working Party of the European Society for Blood and Marrow Transplantation

Beyond its impact on bone health, numerous studies have investigated the immune-regulatory properties of vitamin D and shown how its deficiency can affect outcomes in allogeneic hematopoietic stem cell transplantation (HSCT), particularly in acute or chronic graft-versus-host disease. This survey, carried out by the Transplant Complications Working Party of the European Society for Blood and Marrow Transplantation (EBMT), describes the current clinical practice discrepancies across the EBMT HSCT programs. We therefore recommend the development of evidence-based guidelines to standardize evaluation criteria and to harmonize the management of vitamin D deficiency in patients undergoing allogeneic HSCT.

Individualized in-hospital exercise training program for people undergoing hematopoietic stem cell transplantation: a feasibility study

PURPOSE

The purpose of this study is to evaluate the feasibility of an individualized exercise program for people undergoing hematopoietic stem cell transplantation.

METHODS

This is a feasibility study of an individualized in-hospital exercise training program for people undergoing hematopoietic stem cell transplantation. Participants performed the exercise program based on daily clinical, hemodynamic and hematological assessment. The program was carried out on a daily basis for 20-40 min during their hospital admission. The primary outcome was feasibility (recruitment, adherence and attrition rates) of the exercise program. The secondary outcomes were functional capacity, peripheral muscle strength, and health-related quality of life evaluated on admission and prior to hospital discharge. The adverse events rate was recorded during the intervention.

RESULTS

Twenty-six participants (58% female), aged 40 ± 15 (mean ± SD) years were included. The exercise program feasibility was demonstrated by 100% recruitment, 86% exercise adherence and 12% attrition rates with no adverse events recorded. Significant differences were observed in functional capacity (p = 0.03), upper and lower-limb muscle strength (p = 0.01) from admission to discharge (23 ± 7 d).

CONCLUSIONS

An individualized exercise training program based on daily clinical parameters is feasible for hospitalized patients undergoing hematopoietic stem cell transplantation. This intervention warrants further investigation in a randomized controlled trial. Implications for rehabilitation The individualized in-hospital exercise training program guided by daily clinical, hemodynamic and hematologic parameters is feasible, safe and with good adherence in people undergoing hematopoietic stem cell transplantation. People undergoing hematopoietic stem cell transplantation may improve functional capacity and upper and lower limb muscle strength following in-hospital exercise training program. The individualized in-hospital exercise training program could tentatively be introduced as part of the rehabilitation process in people undergoing hematopoietic stem cell transplantation.

A general practitioner's guide to hematopoietic stem-cell transplantation

Hematopoietic stem-cell transplantation (hsct) is a medical procedure that consists of infusing stem cells after a short course of chemotherapy or radiotherapy, or both. It can be used in the treatment of various cancers, as well as some benign conditions. In the present review, we discuss the various types of hsct and their main indications. The principles of the transplant procedure itself and the basics of recipient selection are reviewed. Special attention is given to both the immediate and the long-term complications of hsct and their management strategies. Hematopoietic stem-cell transplantation is a potentially life-saving procedure and often the only curative option for a variety of diseases; however, it is not without significant toxicities.

Distinct Clinical Manifestations of Thyroid Cancer After Hematopoietic Stem Cell Transplantation

BACKGROUND

The incidence of a secondary solid malignancy after hematopoietic cell transplantation (HCT) is increasing in long-term survivors.

OBJECTIVE

The aim of this study was to compare the clinicopathological characteristics of HCT recipients with secondary thyroid cancer (STC), with those of non-HCT thyroid cancer patients.

METHODS

We retrospectively investigated 5184 patients who received HCT between 1983 and 2016. Of these, 18 patients developed STC and underwent thyroidectomy due to differentiated thyroid cancer. We compared the clinicopathological characteristics of post-HCT thyroid cancer patients (post-HCT group) with those of a primary differentiated thyroid carcinoma cohort (cohort group) from Seoul St. Mary's Hospital.

RESULTS

The mean ages at HCT and thyroidectomy after HCT were 22.0 and 31.8 years, respectively, and the median time interval between HCT and thyroidectomy was 5 years (range 1-16). Compared with the cohort group, the post-HCT group was younger at cancer onset and frequently had a palpable mass at initial diagnosis. The post-HCT group had more aggressive features, including larger tumor size, frequent extrathyroidal extension, lymphatic invasion, perineural invasion, and frequent lateral neck node metastasis and distant metastasis, relative to the cohort group; however, most patients (83.2%) in the post-HCT group were stage I or II. Additionally, BRAF V600E mutation was less frequent in the post-HCT group.

CONCLUSIONS

We found that STC after HCT showed younger presentation and more aggressive clinical presentation. Therefore, a policy of regular screening, including neck ultrasound examination, may promote early detection and treatment in HCT recipients.

Outcomes of patients who developed subsequent solid cancer after hematopoietic cell transplantation

To characterize the outcomes of patients who developed a particular subsequent solid cancer after hematopoietic cell transplantation (HCT), age at cancer diagnosis, survival, and causes of death were compared with the respective primary cancer in the general population, using data from the national HCT registry and population-based cancer registries in Japan. Among 31 867 patients who underwent a first HCT between 1990 and 2013 and had progression-free survival at 1 year, 713 patients developed subsequent solid cancer. The median age at subsequent solid cancer diagnosis was 55 years, which was significantly younger than the 67 years for primary cancer patients in the general population (P < .001). The overall survival probability was 60% at 3 years after diagnosis of subsequent solid cancer and differed according to cancer type. Development of most solid cancers was associated with an increased risk of subsequent mortality after HCT. Subsequent solid cancers accounted for 76% of causes of death. Overall survival probabilities adjusted for age, sex, and year of diagnosis were lower in the HCT population than in the general population for colon, bone/soft tissue, and central nervous system cancers and did not differ statistically for other cancers. In conclusion, most subsequent solid cancers occurred at younger ages than primary cancers, emphasizing the need for cancer screening at younger ages. Subsequent solid cancers showed similar or worse survival compared with primary cancers. Biological and genetic differences between primary and subsequent solid cancers remain to be determined.

Non-GVHD ocular complications after hematopoietic cell transplantation: expert review from the Late Effects and Quality of Life Working Committee of the CIBMTR and Transplant Complications Working Party of the EBMT

Non-graft-versus-host disease (non-GVHD) ocular complications are generally uncommon after hematopoietic cell transplantation (HCT), but can cause prolonged morbidity affecting activities of daily living and quality of life. Here we provide an expert review of non-GVHD ocular complications in a collaboration between transplant physicians and ophthalmologists through the Late Effects and Quality of Life Working Committee of the Center for International Blood and Marrow Transplant Research and the Transplant Complications Working Party of the European Society of Blood and Marrow Transplantation. Complications discussed in this review include cataracts, glaucoma, ocular infections, ocular involvement with malignancy, ischemic microvascular retinopathy, central retinal vein occlusion, retinal hemorrhage, retinal detachment and ocular toxicities associated with medications. We have summarized incidence, risk factors, screening, prevention and treatment of individual complications and generated evidence-based recommendations. Baseline ocular evaluation before HCT should be considered in all patients who undergo HCT. Follow-up evaluations should be considered according to clinical symptoms, signs and risk factors. Better preventive strategies and treatments remain to be investigated for individual ocular complications after HCT. Both transplant physicians and ophthalmologists should be knowledgeable of non-GVHD ocular complications and provide comprehensive collaborative team care.

A survey of infectious diseases and vaccination uptake in long-term hematopoietic stem cell transplant survivors in Australia

BACKGROUND

This cross-sectional survey aimed to establish the prevalence of infectious diseases and vaccination uptake in long-term allogeneic hematopoietic stem cell transplants (HSCT) survivors in New South Wales, in order to reduce long-term post-HSCT morbidity and mortality and enhance long-term care.

PATIENTS AND METHODS

Hematopoietic stem cell transplants survivors aged over 18 years and transplanted between 2000-2012 in New South Wales (NSW) were eligible to participate. Survivors self-completed the Sydney Post BMT Study survey, FACT-BMT (V4), Chronic Graft versus Host Disease (cGVHD) Activity Assessment Self Report, Lee Chronic GvHD Symptom Scale, DASS21, Post Traumatic Growth Inventory, and the Fear of Recurrence Scale.

RESULTS

Of the 583 HSCT survivors contacted, 441 (78%) completed the survey. Respondents included 250 (57%) males and median age was 54 years (range 19-79 years). The median age at the time of transplant was 49 years (Range: 17-71), the median time since HSCT was 5 years (Range: 1-14) and 69% had cGVHD. Collectively, 41.7% of survivors reported a vaccine preventable disease (VPD) with the most common being influenza-like-illness (38.4%), varicella zoster/shingles (27.9%), pap smear abnormalities (9.8%), pneumococcal disease (5.1%), and varicella zoster (chicken pox) (4.6%). Only 31.8% had received the full post-HSCT vaccination schedule, and the majority (69.8%) of these had received the vaccines via their General Practitioner. cGVHD was not found to be a significant factor on multivariate analysis for those who were vaccinated. There was a trend toward lower vaccination rates in patients in a lower income strata.

CONCLUSIONS

Vaccinating post-HSCT survivors to prevent infections and their consequences have an established role in post-HSCT care. Improving rates of post-HSCT vaccination should be a major priority for BMT units.

Non-Graft-versus-Host Disease Ocular Complications after Hematopoietic Cell Transplantation: Expert Review from the Late Effects and Quality of Life Working Committee of the Center for International Blood and Marrow Transplant Research and the Transplant Complications Working Party of the European Society for Blood and Marrow Transplantation

Impact of the 2014 NIH chronic graft-versus-host disease scoring criteria modifications assessed in a large cohort of severely affected patients

In 2005, the National Institutes of Health (NIH) chronic graft-versus-host disease (cGVHD) consensus project provided diagnosis and staging criteria, based mostly on clinical experience and expert opinion. These criteria were revised in 2014, aiming to provide enhanced specificity and clarity. However, the impact of 2014 changes to the original NIH cGVHD severity scoring criteria has not been reported. In this study, 284 patients, prospectively enrolled on the National Cancer Institute's cross-sectional cGVHD natural history study, were scored using the 2005 NIH cGVHD criteria and then rescored according to the 2014 modifications. In comparing the two criteria, 2014 cGVHD global severity scoring resulted in a tendency toward being categorized as milder scores (75 vs. 72% of severe score per 2014, p = 0.0009), with a statistically significant shift in NIH liver and lung scores toward milder categories (p < 0.0001). 2005 and 2014 NIH global severity scores showed a significant association with reduced grip strength (p < 0.0001), reduced joint range of motion (p = 0.0003), and the subspecialist evaluation score (p < 0.0001). Poor survival prediction of the severe NIH lung score is also retained in the new criteria (p = 0.0012). These findings support the use of 2014 cGVHD scoring criteria in continuous efforts to develop better classification systems.

Phase 1 clinical trial evaluating abatacept in patients with steroid-refractory chronic graft-versus-host disease

Costimulatory blockade using abatacept represents a novel therapeutic approach for the treatment of cGVHD. Abatacept resulted in a clinical response in 44% of patients with both decreased prednisone use and T-cell PD-1 expression in responders.

Oral health and dental morbidity in long-term allogeneic blood and marrow transplant survivors in Australia

BACKGROUND

Oral and dental disease is a major cause of long-term morbidity following allogeneic blood and marrow transplantation (Allo-BMT). This study aimed to describe the extent and range of oral and dental complications in BMT recipients and to identify gaps in service provision provided to this high-risk group.

METHODS

Participants were Allo-BMT recipients, aged >18 years, and received transplants between 2000 and 2012 in NSW. They completed seven surveys, the purpose-designed Sydney Post-BMT Study survey and six other validated instruments.

RESULTS

Of 441 respondents, many reported dry mouth (45.1%), dental caries (36.7%), mouth ulcers (35.3%), oral GVHD (35.1%), gingivitis (16.2%), tooth abscess (6.1%) and oral cancer (1.5%). Regular dental visits were reported by 66.2% of survivors. Middle-high income, older age and geographic location showed a positive association with regular dental visits. Of those who did not visit the dentist regularly, 37% stated they did not feel it necessary, 36% reported cost and 20% stated it was not advised by the treating team.

CONCLUSION

Despite oral complications commonly occurring after Allo-BMT, many survivors receive inadequate dental care. These results emphasize the need for improved oral health education, the importance of regular dental checks and improvement in the delivery of dental health services for BMT survivors.

Myeloma patients' experiences of haematopoietic stem cell transplant: A qualitative thematic synthesis

PURPOSE

The aim of this study was to synthesise all qualitative evidence on the experiences of myeloma patients undergoing haematopoietic stem cell transplant (HSCT).

METHOD

A systematic search strategy was developed and a rigorous search of the literature was undertaken searching six databases (CINAHL, Embase, Medline, Psych Info, Ethos and Proquest). The software for systematic reviews www.covidence.org was used to blind screen for eligible papers. Quality appraisal of each study was undertaken using the Critical Appraisal Skills Programme (CASP). Confidence in each finding was assessed using Confidence in the Evidence from Reviews of Qualitative research (CERQual).

RESULTS

Eight qualitative studies (reported in eleven papers and including seventy six myeloma patients) were selected in the final sample for evidence synthesis. Four themes were identified relating to patients' feeling 'dead', disconnecting and isolating themselves, cognitive impairment and engagement with exercise and its benefits in recovery.

CONCLUSIONS

The burden of cognitive functioning among myeloma patients was often under detected. Nurses should ask patients regularly about their memory and any challenges they may be experiencing to their concentration and recall, Exercise during the transplant process can help improve patients' recovery, both physically and psychologically. A structured exercise programme developed by a physiotherapist to suit the needs of each patient should be standard practice in the transplant process.

Allogeneic stem-cell transplantation for myelofibrosis

PURPOSE OF REVIEW

Allogeneic hematopoietic stem-cell transplantation (HSCT) remains the only curative therapy for myelofibrosis. The number of HSCTs performed for this indication has been steadily increasing over the past years, even after the approval of the Janus kinase (JAK) inhibitor, ruxolitinib. This increase may be attributed to improved patient selection based on new prognostic molecular markers, more frequent use of matched unrelated donors, secondary to better (high-resolution) human leukocyte antigen typing and supportive care. Ruxolitinib approval raises new questions regarding the role of JAK inhibitors in the transplant setting.

RECENT FINDINGS

The current review summarizes recent updates on HSCT in myelofibrosis. Predictors for transplant outcomes, and specific considerations related to myelofibrosis patient selection for HSCT (e.g. molecular risk stratification) are reviewed. In addition, this review will consider management of myelofibrosis patients in the peritransplant period, including the role of ruxolitinib in the pretransplant period, pre and posttransplant splenomegaly, transplant protocols, posttransplant follow-up of minimal residual disease and interventions in the event of poor engraftment.

SUMMARY

HSCT remains a highly relevant treatment option for myelofibrosis in the era of JAK inhibitors. Recent advances may contribute to a refined definition of HSCT eligibility and identification of the optimal transplantation time, conditioning protocols and posttransplant management.

Concise Review: Translating Regenerative Biology into Clinically Relevant Therapies: Are We on the Right Path?

Despite approaches in regenerative medicine using stem cells, bio‐engineered scaffolds, and targeted drug delivery to enhance human tissue repair, clinicians remain unable to regenerate large‐scale, multi‐tissue defects in situ. The study of regenerative biology using mammalian models of complex tissue regeneration offers an opportunity to discover key factors that stimulate a regenerative rather than fibrotic response to injury. For example, although primates and rodents can regenerate their distal digit tips, they heal more proximal amputations with scar tissue. Rabbits and African spiny mice re‐grow tissue to fill large musculoskeletal defects through their ear pinna, while other mammals fail to regenerate identical defects and instead heal ear holes through fibrotic repair. This Review explores the utility of these comparative healing models using the spiny mouse ear pinna and the mouse digit tip to consider how mechanistic insight into reparative regeneration might serve to advance regenerative medicine. Specifically, we consider how inflammation and immunity, extracellular matrix composition, and controlled cell proliferation intersect to establish a pro‐regenerative microenvironment in response to injuries. Understanding how some mammals naturally regenerate complex tissue can provide a blueprint for how we might manipulate the injury microenvironment to enhance regenerative abilities in humans.

Deconditioning, fatigue and impaired quality of life in long-term survivors after allogeneic hematopoietic stem cell transplantation

Long-term survivors after allogeneic hematopoietic stem cell transplantation (allo-HSCT) are at high risk for treatment-related adverse events, that may worsen physical capacity and may induce fatigue and disability. The aims of this prospective study were to evaluate exercise capacity in allotransplant survivors and its relationship with fatigue and disability. Patient-reported outcomes and exercise capacity were evaluated in 71 non-relapse patients 1 year after allo-HSCT, using validated questionnaires, cardiopulmonary exercise testing (CPET) with measure of peak oxygen uptake (peakVO₂) and deconditioning, pulmonary function testing, echocardiography and 6-min walk test. A high proportion (75.4%) of allo-HSCT survivors showed abnormal cardiopulmonary exercise testing parameters as compared to predicted normal values, including 49.3% patients who exhibited moderate to severe impairment in exercise capacity and 37.7% patients with physical deconditioning. PeakVO₂ values were not accurately predicted by 6-min walk distances (r = 0.53). Disability and fatigue were strongly associated with decreased peakVO₂ values (p = 0.002 and p = 0.008, respectively). Exercise capacity was reduced in most allo-HSCT long-term survivors. Because reduced exercise capacity was associated with fatigue, disability and a decrease in quality of life, cardiopulmonary exercise testing should be performed in every patient who reports fatigue and disability.

Kidney Pathology after Hematologic Cell Transplantation-A Single-Center Observation Study of Indication Biopsies and Autopsies

Hematopoietic cell transplantation (HCT) is an increasingly used treatment for hematologic malignancies as well as for nonmalignant diseases. Kidney impairment remains an important early and late post-transplantation complication. Although numerous histopathological changes have been reported, the pathophysiology remains incompletely understood. Furthermore, correlations between clinical findings and morphological changes have not been well studied. Between 2000 and 2016, 17 recipients of allogeneic (n = 12) or autologous (n = 5) HCT underwent kidney biopsy for either proteinuria or deterioration of kidney function at our center. The most common biopsy findings were therapy-related changes with thrombotic microangiopathy (n = 5), calcineurin inhibitor toxicity (n = 4), and membranous glomerulonephritis (n = 3), representing the majority of cases in this category. In addition, kidney findings from 137 autopsies performed between 1995 and March 2017 were analyzed. The most common changes were acute kidney injury (n = 55), most likely due to the patients' premortal deteriorated state, and thrombotic microangiopathy (n = 14). Several cases demonstrated involvement by either infectious agents (n = 6) or tumors (n = 9). Distinct kidney diseases, such as glomerulonephritis, were rare (3% of cases). Uncommon and yet rarely described diagnoses for this patient cohort were IgG4-related tubulointerstitial nephritis and fibrillary nephritis. This study provides a comprehensive overview of the histomorphological findings in kidney biopsy specimens from HCT recipients. Along with treatment-related complications, one putative correlate of chronic GVHD of the kidney could be documented: membranous glomerulonephritis. In contrast, no morphological correlate of acute GVHD of the kidney was identified. Findings at the time of autopsy varied greatly, spanning a wider range than those of indication biopsies.

Coordination of Care in Survivorship After Treatment of Hematological Malignancies-The Journey is Not Over Yet

The number of adult survivors of hematologic malignancies is steadily growing. This population is at moderate to high risk for cancer survivorship issues including physical and psychosocial sequelae of intensive cancer therapies. Although cancer survivorship is a growing field in pediatric and solid tumor oncology, survivorship care and research has often been overlooked in the hematologic malignancies. In this review, we focus specifically on survivorship issues related to adult patients with hematologic malignancies and provide commentary on the role of cancer survivorship, proposed survivorship care models, and the economic and health policy obstacles associated with moving the cancer survivorship field forward in this very important patient population.

Lichenoid and interface dermatoses

The terms 'lichenoid' and 'interface' dermatitis are often used interchangeably to describe an inflammatory pattern characterized histologically by damage to the basal keratinocytes in the epidermis. The mechanism of cell damage of such cells is now best understood as apoptosis, or programmed cell death. This inflammatory pattern of dermatoses, is also accompanied frequently by a band of lymphocytes and histiocytes in the superficial dermis, that often obscures the dermal-epidermal junction, hence the term 'lichenoid'. A discussion of the more common lichenoid/interface dermatitides encountered in the routine clinical practice encompasses the following entities: lichen planus, lupus erythematosus, dermatomyositis, erythema multiforme, graft versus host disease, fixed drug reactions, and multiple others.
