We designed a prospective, observational study enrolling patients presenting for treatment of acute myeloid leukemia (AML) at 13 institutions to analyze associations between hematopoietic cell transplantation (HCT) and survival, quality of life (QOL), and function in: the entire cohort, those aged ≥65 years, those with high comorbidity burden, intermediate cytogenetic risk, adverse cytogenetic risk, and first complete remission with or without measurable residual disease. Patient were assessed 8 times over 2 years. Time-dependent regression models were used. Among 692 patients that were evaluable, 46% received HCT with a 2-year survival of 58%. In unadjusted models, HCT was associated with reduced risks of mortality most of the subgroups. However, after accounting for covariates associated with increased mortality (age, comorbidity burden, disease risks, frailty, impaired QOL, depression, and impaired function), the associations between HCT and longer survival disappeared in most subgroups. Although function, social life, performance status, and depressive symptoms were better for those selected for HCT, these health advantages were lost after receiving HCT. Recipients and nonrecipients of HCT similarly ranked and expected cure as main goal of therapy, whereas physicians had greater expectations for cure than the former. Accounting for health impairments negates survival benefits from HCT for AML, suggesting that the unadjusted observed benefit is mostly owing to selection of the healthier candidates. Considering patients’ overall expectations of cure but also the QOL burdens of HCT motivate the need for randomized trials to identify the best candidates for HCT. This trial was registered at www.clinicaltrials.gov as #NCT01929408.

Pretransplant respiratory virus infections (RVIs) have been shown to negatively affect hematopoietic cell transplantation (HCT) outcomes. The impact of and need for delay of HCT for pretransplant infection with human rhinovirus (HRV) or endemic human coronavirus (HCoV; 229E, OC43, NL63, and HKU1) remain controversial. We analyzed the impact of symptomatic RVI within ≤90 days before HCT on overall mortality, posttransplant lower respiratory tract disease (LRD), and days alive and out of hospital (DAOH) by day 100 post-HCT in multivariable models. Among 1,643 adult HCT recipients (58% allogeneic recipients), 704 (43%) were tested for RVI before HCT, and 307 (44%) tested positive. HRV was most commonly detected (56%). Forty-five (15%) of 307 HCT recipients had LRD with the same virus early after HCT. Pretransplant upper respiratory tract infection (URI) with influenza, respiratory syncytial virus, adenovirus, human metapneumovirus, parainfluenza virus, HRV, or endemic HCoV was not associated with increased overall mortality or fewer DAOH. However, in allogeneic recipients who received myeloablative conditioning, LRD due to any respiratory virus, including HRV alone, was associated with increased overall mortality (adjusted hazard ratio, 10.8 [95% confidence interval, 3.29-35.1] for HRV and 3.21 [95% confidence interval, 1.15-9.01] for all other viruses). HRV LRD was also associated with fewer DAOH. Thus, the presence of LRD due to common respiratory viruses, including HRV, before myeloablative allogeneic HCT was associated with increased mortality and hospitalization. Pretransplant URI due to HRV and endemic HCoV was not associated with these outcomes. Improved management strategies for pretransplant LRD are warranted.

Background: Childhood cancer survivors (CCS) are more insulin resistant and have higher levels of several cardiovascular risk factors even while still children. This study examines specific treatment exposures associated with cardiovascular risk factors and insulin resistance.Methods: CCS of ages 9 to 18 years at study entry and in remission 5 years or more from diagnosis (n = 319) and 208 sibling controls were recruited into this cross-sectional study that included physiologic assessment of insulin resistance (hyperinsulinemic euglycemic clamp) and assessment of cardiovascular risk factors. Regression and recursive tree modeling were used to ascertain treatment combinations associated with insulin resistance and cardiovascular risk.Results: Mean current age of CCS was 14.5 years and 54% were male (siblings 13.6 years, 54% male). Diagnoses included leukemia (35%), brain tumors (36%), solid tumors (33%), or lymphoma (6%). Among CCS, analysis of individual chemotherapy agents failed to find associations with cardiovascular risk factors or insulin resistance. Compared with siblings, insulin resistance was significantly higher in CCS who received platinum plus cranial radiotherapy (CRT, 92% brain tumors) and in those who received steroids but no platinum (majority leukemia). Insulin resistance did not differ between CCS who received surgery alone versus siblings. Within survivor comparisons failed to elucidate treatment combinations that increased insulin resistance compared with those who received surgery only.Conclusions: Exposure to platinum, CRT, or steroids is associated with insulin resistance and cardiovascular risk factors and should be taken into consideration in the development of screening recommendations for cardiovascular risk.Impact: Earlier identification of CCS who may benefit from targeted prevention efforts may reduce their future risk of cardiovascular disease.

Background: Women with a history of chest radiotherapy have an increased risk of breast cancer; however, many do not undergo annual recommended screening mammography. We sought to characterize the relationship between mammography and potentially modifiable factors, with the goal of identifying targets for intervention to improve utilization.Methods: Of 625 female participants sampled from the Childhood Cancer Survivor Study, who were treated with chest radiotherapy, 551 responded to a survey about breast cancer screening practices. We used multivariate Poisson regression to assess several lifestyle and emotional factors, health care practices, and perceived breast cancer risk, in relation to reporting a screening mammogram within the last two years.Results: Women who had a Papanicolaou test [prevalence ratio (PR): 1.77; 95% confidence interval (CI) 1.26–2.49], and who perceived their breast cancer risk as higher than the average woman were more likely to have had a mammogram (PR, 1.26; 95% CI, 1.09–1.46). We detected an attenuated effect of echocardiogram screening [PR, 0.70; 95% CI (0.52–0.95)] on having a mammogram among older women compared with younger women. Smoking, obesity, physical activity, coping, and symptoms of depression and somatization were not associated with mammographic screening.Conclusion: Our findings suggest that compliance with routine and risk-based screening can be an important indicator of mammography in childhood cancer survivors. In addition, there is a need to ensure women understand their increased breast cancer risk, as a means to encouraging them to follow breast surveillance guidelines.Impact: Screening encounters could be used to promote mammography compliance in this population.

Although pediatric lower extremity sarcoma once was routinely treated with amputation, multiagent chemotherapy as well as the evolution of tumor resection and reconstruction techniques have enabled the wide adoption of limb salvage surgery (LSS). Even though infection and tumor recurrence are established risk factors for early amputation (5 years) after LSS, the frequency of and factors associated with late amputation (≥ 5 years from diagnosis) in children with sarcomas are not known. Additionally, the resulting psychosocial and physical outcomes of these patients compared with those treated with primary amputation or LSS that was not complicated by subsequent amputation are not well studied. Studying these outcomes is critical to enhancing the quality of life of patients with sarcomas.(1) How have treatments changed over time in patients with lower extremity sarcoma who are included in the Childhood Cancer Survivor Study (CCSS), and did primary treatment with amputation or LSS affect overall survival at 25 years among patients who had survived at least 5 years from diagnosis? (2) What is the cumulative incidence of amputation after LSS for patients diagnosed with pediatric lower extremity sarcomas 25 years after diagnosis? (3) What are the factors associated with time to late amputation (≥ 5 years after diagnosis) in patients initially treated with LSS for lower extremity sarcomas in the CCSS? (4) What are the comparative social, physical, and emotional health-related quality of life (HRQOL) outcomes among patients with sarcoma treated with primary amputation, LSS without amputation, or LSS complicated by late amputation, as assessed by CCSS follow-up questionnaires, the SF-36, and the Brief Symptom Inventory-18 at 20 years after cancer diagnosis?The CCSS is a long-term follow-up study that began in 1994 and is coordinated through St. Jude Children's Research Hospital. It is a retrospective study with longitudinal follow-up of more than 38,000 participants treated for childhood cancer when younger than 21 years at one of 31 collaborating institutions between 1970 and 1999 in the United States and Canada. Participants were eligible for enrollment in the CCSS after they had survived 5 years from diagnosis. Within the CCSS cohort, we included participants who had a diagnosis of lower extremity sarcoma treated with primary amputation (547 patients with a mean age at diagnosis of 13 ± 4 years) or primary LSS (510 patients with a mean age 14 ± 4 years). The LSS cohort was subdivided into LSS without amputation, defined as primary LSS without amputation at the time of latest follow-up; LSS with early amputation, defined as LSS complicated by amputation occurring less than 5 years from diagnosis; or LSS with late amputation, defined as primary LSS in study patients who subsequently underwent amputation 5 years or more from cancer diagnosis. The cumulative incidence of late amputation after primary LSS was estimated. Cox proportional hazards regression with time-varying covariates identified factors associated with late amputation. Modified Poisson regression models were used to compare psychosocial, physical, and HRQOL outcomes among patients treated with primary amputation, LSS without amputation, or LSS complicated by late amputation using validated surveys.More study participants were treated with LSS than with primary amputation in more recent decades. The overall survival at 25 years in this population who survived 5 years from diagnosis was not different between those treated with primary amputation (87% [95% confidence interval [CI] 82% to 91%]) compared with LSS (88% [95% CI 85% to 91%]; p = 0.31). The cumulative incidence of amputation at 25 years after cancer diagnosis and primary LSS was 18% (95% CI 14% to 21%). With the numbers available, the cumulative incidence of late amputation was not different among study patients treated in the 1970s (27% [95% CI 15% to 38%]) versus the 1980s and 1990s (19% [95% CI 13% to 25%] and 15% [95% CI 10% to 19%], respectively; p = 0.15). After controlling for gender, medical and surgical treatment variables, cancer recurrence, and chronic health conditions, gender (hazard ratio [HR] 2.02 [95% CI 1.07 to 3.82]; p = 0.03) and history of prosthetic joint reconstruction (HR 2.58 [95% CI 1.37 to 4.84]; p = 0.003) were associated with an increased likelihood of late amputation. Study patients treated with a primary amputation (relative risk [RR] 2.04 [95% CI 1.15 to 3.64]) and LSS complicated by late amputation (relative risk [RR] 3.85 [95% CI 1.66 to 8.92]) were more likely to be unemployed or unable to attend school than patients treated with LSS without amputation to date. The CCSS cohort treated with primary amputation and those with LSS complicated by late amputation reported worse physical health scores than those without amputation to date, although mental and emotional health outcomes did not differ between the groups.There is a substantial risk of late amputation after LSS, and both primary and late amputation status are associated with decreased physical HRQOL outcomes. Children treated for sarcoma who survive into adulthood after primary amputation and those who undergo late amputation after LSS may benefit from interventions focused on improving physical function and reaching educational and employment milestones. Efforts to improve the physical function of people who have undergone amputation either through prosthetic design or integration into the residuum should be supported. Understanding factors associated with late amputation in the setting of more modern surgical approaches and implants will help surgeons more effectively manage patient expectations and adjust practice to mitigate these risks over the life of the patient.Level III, therapeutic study.

We assessed novel factors and the immunodeficiency scoring index (ISI) to predict progression to lower respiratory tract infection (LRTI) among hematopoietic cell transplant (HCT) recipients presenting with upper respiratory tract infection (URTI) with 12 viruses in the PCR era. We retrospectively analyzed the first respiratory virus detected by multiplex PCR in allogeneic HCT recipients (4/2008-9/2018). We used Cox proportional hazards models to examine factors for progression to LRTI within 90 days among patients presenting with URTI. A total of 1027 patients (216 children and 811 adults) presented with URTI only. Among these, 189 (18%) progressed to LRTI (median: 12 days). Multivariable models demonstrated a history of 1 transplant, age ≥40 years, time post-HCT (≤30 days), systemic steroids, hypoalbuminemia, hyperglycemia, cytopenia, and high ISI (scores 7-12) were associated with an increased risk of progression to LRTI. Respiratory syncytial virus and human metapneumovirus showed the highest progression risk. Patients with ≥3 independent risk factors or high ISI scores were highly likely to progress to LRTI. We identified novel risk factors for progression to LRTI, including history of multiple transplants and hyperglycemia, suggesting an intervention opportunity with glycemic control. ISI and number of risk factors appear to predict disease progression across several viruses.

Background: Survivors of childhood cancer are at risk for therapy-related subsequent malignant neoplasms (SMN), including thyroid SMN. Telomere length (TL) is associated with cancer risk, but the relationship between TL and SMN risk among survivors is less clear. Methods: We conducted a nested, matched case–control study of radiation-exposed 15-year+ adult survivors of childhood cancer with thyroid SMN (cases) and without SMN (controls). Forty-six cases were matched to 46 controls by primary diagnosis, chemotherapy (yes/no), radiation field, and follow-up duration. Lymphocyte TL (LTL) was measured by telomere flow-FISH cytometry using blood samples banked at a mean of 38.9 years (cases), 39.2 years (controls). Genetic variation in telomere genes was assessed by whole genome sequencing. Point estimates for LTL Results: Cases had shorter median LTL than controls in three out of four leukocyte subsets. Cases were more likely to have NK cell LTL Conclusions: Long-term survivors have shorter than expected LTL, a finding that is more pronounced among survivors with thyroid SMN. Impact: The long-term impact of childhood cancer treatment on immune function is poorly understood. Our findings support immune function studies in larger survivor cohorts to assess long-term deficits in adaptive and innate immunity that may underlie SMN risk.

Background: Prior studies have identified that survivors of childhood acute lymphoblastic leukemia (ALL) report poor health status. It is unknown how risk-stratified therapy impacts the health status of ALL survivors. Methods: We estimated and compared the prevalence of self-reported poor health status among adult (≥18 years) survivors of childhood ALL diagnosed at age Results: Among 5,119 survivors and 4,693 siblings, survivors were more likely to report poor health status in each domain including poor general health (13.5% vs. 7.4%; PR = 1.92; 95% CI, 1.69–2.19). Compared with 70s, 90sSR and 90sHR were less likely to report poor general health (90sSR: PR = 0.75; 95% CI, 0.57–0.98; 90sHR: PR = 0.58; 95% CI, 0.39–0.87), functional impairment (90sSR: PR = 0.56; 95% CI, 0.42–0.76; 90sHR: PR = 0.63; 95% CI, 0.42–0.95), and activity limitations (90sSR: 0.61; 95% CI, 0.45–0.83; 90sHR: PR = 0.59; 95% CI, 0.38–0.91). An added adjustment for chronic conditions in multivariable models partially attenuated 90sSR risk estimates. Conclusions: Risk-stratified ALL therapy has succeeded in reducing risk for poor general health, functional impairment, and activity limitations among more recent survivors of standard- and high-risk therapy. Impact: Future research into the relationship between risk-stratified therapy, health status, and late health outcomes may provide new opportunities to further improve late morbidity among survivors.

CLAG-M (cladribine, high-dose cytarabine [HiDAC], G-CSF, mitoxantrone)/CLAG are contemporary intensive chemotherapy regimens associated with higher and deeper complete remission rates than 7+3 (cytarabine, anthracycline)/HiDAC, but with greater myelosuppression and potential infection risks. Here, we compared the cumulative incidence (CI) and patterns of invasive fungal disease (IFD) between these regimens by identifying proven/probable and possible cases of IFD following CLAG-M (n=332) and 7+3 (n=115) chemotherapy and subsequent treatment cycles in adults ≥18 years old with newly diagnosed (ND) or relapsed/refractory (R/R) AML or other high-grade myeloid neoplasms between 2006 and 2018. By 90 days (D90) after initiating treatment, the CI of proven/probable IFD was 20% with CLAG-M and 12% with 7+3 (p=0.17). There was no significant difference in the CI of IFD between ND CLAG-M and R/R CLAG-M. Without mold-active prophylaxis, the D90 CI of proven/probable IFD was significantly higher in the CLAG-M than the 7+3 cohort (28% versus 11%; p=0.007), but this difference was mitigated with mold-active prophylaxis (CLAG-M, 7.5%; 7+3, 0%; p=0.65). After each chemotherapy treatment cycle, the CI of newly diagnosed IFD was similar, ranging from 15-20%. Use of mold-active prophylaxis was the only factor associated with reduced IFD risk in adjusted models (HR, 0.32; 95% confidence interval, 0.18-0.56). Together, these data indicate that the IFD risk with CLAG-M is higher than with 7+3 in the absence of mold-active prophylaxis; use of mold-active prophylaxis mitigates this risk.

Background CMV reactivation is occasionally detected during the work-up for hematopoietic cell transplantation (HCT) but its natural history and significance on posttransplant CMV risk is unknown. Methods CMV seropositive 1st HCT allograft recipients in the preemptive therapy era (2010-17) were analyzed. CMV PCR testing was routinely performed before and after HCT. Cumulative incidences of CMV reactivation after HCT were calculated at multiple PCR thresholds by pre-HCT viral loads (peak: < or >150 IU/mL; last prior to HCT positive vs positive to negative). Treatment of pre-HCT reactivation was recommended for viral loads >50 IU/mL. Multivariable Cox proportional hazard models were used to determine the association of pre-transplant CMV reactivation on post-HCT CMV reactivation at different PCR thresholds. Results Among 1536 patients (median age 50 y, range 0.1-81), 155 (10%), 53 (3.5%) and 24 (1.6%) had pre-HCT reactivation in the month before HCT at any level, >150 IU/mL, and >500 IU/mL, respectively. Pre-transplant CMV reactivation was associated with a higher risk of post-HCT CMV reactivation at all examined PCR thresholds and with CMV disease after transplantation in cumulative incidence (Figure 1) and multivariable analyses (Figure 2A). Patients who had CMV DNA detected that subsequently became negative before HCT (with or without treatment) had a lower risk than those who proceeded to HCT with viremia (Figure 2B). Cumulative Incidence of CMV Infection and Disease Multivariable Cox Regression Conclusion CMV reactivation occurs pre-HCT in ∼10% of CMV seropositive HCT candidates and is a risk factor for post-HCT CMV events at all severity levels, placing a HCT recipient in a high-risk category. Thus, pre-HCT PCR testing and antiviral treatment as well as the use of optimized posttransplant antiviral or immunotherapy prevention strategies are recommended. Disclosures Joshua A.

Background Respiratory virus infections (RVIs) in adult hematopoietic cell transplant (HCT) candidates have been shown to impact posttransplant outcomes; however, there are few studies in pediatric patients. We sought to evaluate the role of specific viruses and the location of viral infection on post HCT outcomes. Methods We evaluated allogeneic pediatric HCT recipients receiving myeloablative conditioning from 3/2010–3/2018. All patients had a multiplex PCR for RVIs prior to HCT, regardless of symptoms. Delaying HCT was recommended when feasible for RSV, parainfluenza, metapneumovirus, adenovirus, and influenza, but not routinely for human rhinovirus (HRV) and endemic coronaviruses. We utilized Cox proportional hazards models to evaluate progression to lower respiratory disease (LRD) post HCT and linear regression models to evaluated days alive and out of hospital (DAOH) by 100 days post HCT. Results Of 310 allogeneic HCT recipients receiving myeloablative conditioning, 133 (43%) were positive for a RVI before HCT. Baseline characteristics were notable for differences for age, recipient CMV serostatus, and delayed HCT (Table 1). The most common RVI was HRV (97, 73%) and 81 (61%) patients were symptomatic at the time of detection. Most patients had a URI (92%) and 11 patients had LRD (3 proven, 8 possible). In univariate analysis, HRV as virus type was associated with fewer DAOH and preHCT URI as location of viral infection (with and without symptoms) trended towards fewer DAOH (Figure 1a). When adjusted for age, preHCT lymphocyte count, cell source, and conditioning regimen, both HRV and preHCT URI showed a trend towards fewer DAOH, but no significant association was found (Figure 1b,c). Twenty patients progressed to LRD after HCT with the same preHCT RVI; no factors, including delay of transplant, were associated with reduced progression to LRD. (A) Univariable linear regression for DAOH, (B) Multivariable linear regression for DAOH by viral type, (C) Multivariable linear regression for DAOH by viral location and symptom composite. Conclusion In this single center study, HRV as virus type and URI as location of viral infection before myeloablative allogeneic HCT were associated with increased hospitalization after HCT, but not in multivariate models. Larger multicenter studies are needed to provide timely evaluation and adequate statistical power to definitively determine role of URI versus LRD and the impact of transplant delay and treatment strategies.

Background We previously demonstrated frequent detection of HHV-6B DNA in bronchoalveolar lavage fluid (BALF) and its positive association with mortality in HCT recipients from 1992-2015 with lower respiratory tract disease (LRTD). Whether these findings remain pertinent in contemporary patients, the additive value of testing for viral gene transcription, and the correlation of HHV-6 detection in blood and BALF, are unknown. Methods We conducted a prospective study of allogeneic HCT recipients undergoing BAL for LRTD within 120 days of HCT at three cancer centers from 2015-2019. We collected and tested paired blood and BALF for HHV-6B DNA by qPCR and HHV-6B mRNA (U38 and U90 gene transcripts) among DNA positive samples using RT-qPCR. We described the detection of HHV-6B DNA and mRNA in blood and BALF, generated receiver operating characteristic (ROC) curves to determine the ability of BALF HHV-6B DNA detection to predict HHV-6B mRNA detection, and analyzed the association of HHV-6B DNA detection with mortality. Results We enrolled 116 allogeneic HCT recipients who underwent 125 BALs. HHV-6B DNA was detected in 45 of 122 BALF (37%) compared to 19 of 124 (15%) plasma samples. Among the 45 BALF samples with HHV-6B DNA detected, either HHV-6B mRNA transcript was detected in 22 (49%) (Figure 1). BALF HHV-6B DNA ≥ 218 copies/ml had an area under the curve of 0.93 for predicting detection of BALF viral mRNA (Figure 2). In turn, patients with BALF HHV-6B DNA ≥ 218 copies/mL had increased risk for mortality and death due to LRTD within 60 days after the BAL (Figure 3). This association remained after adjustment for age, oxygen use, and steroid use at the time of BAL in a multivariable Cox model (Figure 3). Conclusion HHV-6B was detected more frequently in BALF than plasma, suggesting compartment-specific reactivation. BALF HHV-6B DNA ≥ 218 copies/mL had high sensitivity and specificity for detection of viral gene transcription in BALF and was associated with increased mortality; this viral load is strikingly similar to the BALF viral load threshold of 251 copies/mL associated with mortality in our prior retrospective study. Together, these data suggest transcriptionally active HHV-6B is a clinically impactful pulmonary pathogen in contemporary HCT recipients. Disclosures Joshua A.

Background The objective of this study was to examine long-term outcomes among children newly diagnosed with cancer who were treated in dexrazoxane-containing clinical trials. Methods P9404 (acute lymphoblastic leukemia/lymphoma [ALL]), P9425 and P9426 (Hodgkin lymphoma), P9754 (osteosarcoma), and Dana-Farber Cancer Institute 95-01 (ALL) enrolled 1308 patients between 1996 and 2001: 1066 were randomized (1:1) to doxorubicin with or without dexrazoxane, and 242 (from P9754) were nonrandomly assigned to receive dexrazoxane. Trial data were linked with the National Death Index, the Organ Procurement and Transplantation Network, the Pediatric Health Information System (PHIS), and Medicaid. Osteosarcoma survivors from the Childhood Cancer Survivor Study (CCSS; n = 495; no dexrazoxane) served as comparators in subanalyses. Follow-up events were assessed with cumulative incidence, Cox regression, and Fine-Gray methods. Results In randomized trials (cumulative prescribed doxorubicin dose, 100-360 mg/m2 ; median follow-up, 18.6 years), dexrazoxane was not associated with relapse (hazard ratio [HR], 0.84; 95% confidence interval [CI], 0.63-1.13), second cancers (HR, 1.19; 95% CI, 0.62-2.30), all-cause mortality (HR, 1.07; 95% CI, 0.78-1.47), or cardiovascular mortality (HR, 1.45; 95% CI, 0.41-5.16). Among P9754 patients (all exposed to dexrazoxane; cumulative doxorubicin, 450-600 mg/m2 ; median follow-up, 16.6-18.4 years), no cardiovascular deaths or heart transplantation occurred. The 20-year heart transplantation rate among CCSS osteosarcoma survivors (mean doxorubicin, 377 ± 145 mg/m2 ) was 1.6% (vs 0% in P9754; P = .13). Among randomized patients, serious cardiovascular outcomes (cardiomyopathy, ischemic heart disease, and stroke) ascertained by PHIS/Medicaid occurred less commonly with dexrazoxane (5.6%) than without it (17.6%; P = .02), although cardiomyopathy rates alone did not differ (4.4% vs 8.1%; P = .35). Conclusions Dexrazoxane did not appear to adversely affect long-term mortality, event-free survival, or second cancer risk.

BACKGROUND AND PURPOSE We previously evaluated late cardiac disease in long-term survivors in the Childhood Cancer Survivor Study (CCSS) based on heart radiation therapy (RT) doses estimated from an age-scaled phantom with a simple atlas-based heart model (HAtlas). We enhanced our phantom with a high-resolution CT-based anatomically realistic and validated age-scalable cardiac model (HHybrid). We aimed to evaluate how this update would impact our prior estimates of RT-related late cardiac disease risk in the CCSS cohort. METHODS We evaluated 24,214 survivors from the CCSS diagnosed from 1970 to 1999. RT fields were reconstructed on an age-scaled phantom with HHybrid and mean heart dose (Dm), percent volume receiving ≥ 20 Gy (V20) and ≥ 5 Gy with V20 = 0 ( [Formula: see text] ) were calculated. We reevaluated cumulative incidences and adjusted relative rates of grade 3-5 Common Terminology Criteria for Adverse Events outcomes for any cardiac disease, coronary artery disease (CAD), and heart failure (HF) in association with Dm, V20, and [Formula: see text] (as categorical variables). Dose-response relationships were evaluated using piecewise-exponential models, adjusting for attained age, sex, cancer diagnosis age, race/ethnicity, time-dependent smoking history, diagnosis year, and chemotherapy exposure and doses. For relative rates, Dm was also considered as a continuous variable. RESULTS Consistent with previous findings with HAtlas, reevaluation using HHybrid dosimetry found that, Dm ≥ 10 Gy, V20 ≥ 0.1%, and [Formula: see text] ≥ 50% were all associated with increased cumulative incidences and relative rates for any cardiac disease, CAD, and HF. While updated risk estimates were consistent with previous estimates overall without statistically significant changes, there were some important and significant (P

We designed a prospective, observational study enrolling patients presenting for treatment of AML at 13 institutions to analyze associations between hematopoietic cell transplantation (HCT) and survival, quality of life (QOL), function and geriatric health, in 6 groups: 1) the entire cohort, 2) ≥65 years old, 3) high comorbidity burden, 4) intermediate cytogenetic-risk, 5) adverse cytogenetic-risk, and 6) first complete remission with or without measurable residual disease. Patient health and preferences were assessed eight times across 2 years. Time-dependent regression models were used. Among 692 evaluable patients, 46% received HCT with 2-year survival of 58%. In unadjusted models, HCT was associated with reduced risks of mortality in the entire group and most of the subgroups. However, after accounting for covariates associated with increased mortality (age, comorbidity-burden, disease risks, frailty, impaired QOL, depression, and impaired function), the associations between HCT and longer survival disappeared in all groups. While function, social life, performance status, and depressive symptoms were better for those selected for HCT compared to those who were not, these health advantages were lost after receiving HCT. Recipients and non-recipients of HCT similarly ranked and expected cure as main goal of therapy, while physicians expected more cure for the formers. Accounting for health impairments negate survival benefits from HCT for AML, suggesting that the unadjusted observed benefit is due mostly to selection of the healthier candidates. Considering patients' overall expectations of cure but also the QOL burdens of HCT motivate the need for randomized trials to identify the best candidates for HCT.

PURPOSE To determine the incidence of serious chronic health conditions among survivors of pediatric Hodgkin lymphoma (HL), compare by era of therapy and by selected cancer therapies, and provide estimates of risks associated with contemporary therapy. METHODS Assessing 2,996 5-year HL survivors in the Childhood Cancer Survivor Study diagnosed from 1970 to 1999, we examined the cumulative incidence of severe to fatal chronic conditions (grades 3-5) using self-report conditions, medically confirmed subsequent malignant neoplasms, and cause of death based on the National Death Index. We used multivariable regression models to estimate hazard ratios (HRs) per decade and by key treatment exposures. RESULTS HL survivors were of a mean age of 35.6 years (range, 12-58 years). The cumulative incidence of any grade 3-5 condition by 35 years of age was 31.4% (95% CI, 29.2 to 33.5). Females were twice as likely (HR, 2.1; 95% CI, 1.8 to 2.4) to have a grade 3-5 condition compared with males. From the 1970s to the 1990s, there was a 20% reduction (HR, 0.8; 95% CI, 0.7 to 0.9) in decade-specific risk of a grade 3-5 condition ( P trend = .002). In survivors who had a recurrence and/or hematopoietic cell transplant, the risk of a grade 3-5 condition was substantially elevated, similar to that of survivors treated with high-dose, extended-field radiotherapy (HR, 1.2; 95% CI, 0.9 to 1.5). Compared with survivors treated with chest radiotherapy ≥ 35 Gy in combination with an anthracycline or alkylator, a contemporary regimen for low-intermediate risk HL was estimated to lead to a 40% reduction in risk of a grade 3-5 condition (HR, 0.6; 95% CI, 0.4 to 0.8). CONCLUSION This study demonstrates that risk-adapted therapy for pediatric HL has resulted in a significant reduction in serious long-term outcomes.

OBJECTIVE: To characterize the prevalence and predictors of concerns regarding future health and cancer risk among siblings of childhood cancer survivors. METHODS: This study reports longitudinal data (baseline and follow-up) from 3,969 adult siblings (median age = 29 [range 18 – 56] years) of long-term survivors of childhood cancer (median time since diagnosis 19.6 [9.6–33.8] years). Self-reported future health and cancer risk concerns (concerned vs not concerned) were assessed. Demographics and health data reported by both the siblings and their matched cancer survivors were examined as risk factors for health concerns using multivariable logistic regression. RESULTS: Percentage of siblings reporting future health and cancer risk concerns, respectively, decreased across decade of survivors’ diagnosis: 1970s (73.3%; 63.9%), 1980s (67.2%; 62.6%), 1990s (45.7%; 52.3%). Risk factors associated with future health concerns included sibling chronic health conditions (grade 2 Odds Ratio [OR]=1.57, 95% CI: 1.12–2.20; grade 3–4 OR=1.86, 95% CI: 1.18–2.94; compared to less than grade 2). Risk factors associated with future cancer concerns included sibling chronic health conditions (grade 2 OR=1.43, 95% CI: 1.05–1.94;’ grade 3–4 OR=1.64, 95% CI: 1.09–2.47; compared to less than grade 2). CONCLUSIONS: Sibling concerns regarding future health and cancer have diminished in recent decades. There are subgroups of siblings that are at-risk for future health and cancer risk concerns. IMPLICATIONS FOR CANCER SURVIVORS: Routine screening of concerns in at-risk siblings of survivors of childhood cancer may benefit the siblings of cancer survivors. These individuals may benefit from early interventions during diagnosis and treatment of their siblings.

Five-year survival following childhood acute myeloid leukemia (AML) has increased following improvements in treatment and supportive care. Long-term health outcomes are unknown. To address this, cumulative incidence of late mortality and grades 3 to 5 chronic health condition (CHC) were estimated among 5-year AML survivors diagnosed between 1970 and 1999. Survivors were compared by treatment group (hematopoietic cell transplantation [HCT], chemotherapy with cranial radiation [chemo + CRT], chemotherapy only [chemo-only]), and diagnosis decade. Self-reported health status was compared across treatments, diagnosis decade, and with siblings. Among 856 survivors (median diagnosis age, 7.1 years; median age at last follow-up, 29.4 years), 20-year late mortality cumulative incidence was highest after HCT (13.9%; 95% confidence interval [CI], 10.0%-17.8%; chemo + CRT, 7.6%; 95% CI, 2.2%-13.1%; chemo-only, 5.1%; 95% CI, 2.8%-7.4%). Cumulative incidence of mortality for HCT survivors diagnosed in the 1990s (8.5%; 95% CI, 4.1%-12.8%) was lower vs those diagnosed in the 1970s (38.9%; 95% CI, 16.4%-61.4%). Most survivors did not experience any grade 3 to 5 CHC after 20 years (HCT, 45.8%; chemo + CRT, 23.7%; chemo-only, 27.0%). Furthermore, a temporal reduction in CHC cumulative incidence was seen after HCT (1970s, 76.1%; 1990s, 38.3%; P = .02), mirroring reduced use of total body irradiation. Self-reported health status was good to excellent for 88.2% of survivors; however, this was lower than that for siblings (94.8%; P < .0001). Although HCT is associated with greater long-term morbidity and mortality than chemotherapy-based treatment, gaps have narrowed, and all treatment groups report favorable health status.

Data are limited regarding risk factors for lower respiratory tract infection (LRTI) caused by seasonal human coronaviruses (HCoVs) and the significance of virologic documentation by bronchoalveolar lavage (BAL) on outcomes in hematopoietic cell transplant (HCT) recipients. We retrospectively analyzed patients undergoing allogeneic HCT (4/2008-9/2018) with HCoV (OC43/NL63/HKU1/229E) detected by polymerase chain reaction during conditioning or post-HCT. Risk factors for all manifestations of LRTI and progression to LRTI among those presenting with HCoV upper respiratory tract infection (URTI) were analyzed by logistic regression and Cox proportional hazard models, respectively. Mortality rates following HCoV LRTI were compared according to virologic documentation by BAL. A total of 297 patients (61 children and 236 adults) developed HCoV infection as follows: 254 had URTI alone, 18 presented with LRTI, and 25 progressed from URTI to LRTI (median, 16 days; range, 2-62 days). Multivariable logistic regression analyses showed that male sex, higher immunodeficiency scoring index, albumin 150 mg/dL, and presence of respiratory copathogens were associated with occurrence of LRTI. Hyperglycemia with steroid use was associated with progression to LRTI (P < .01) in Cox models. LRTI with HCoV detected in BAL was associated with higher mortality than LRTI without documented detection in BAL (P < .01). In conclusion, we identified factors associated with HCoV LRTI, some of which are less commonly appreciated to be risk factors for LRTI with other respiratory viruses in HCT recipients. The association of hyperglycemia with LRTI might provide an intervention opportunity to reduce the risk of LRTI., Key Points • We demonstrate risk factors for HCoV LRTI in allogeneic HCT recipients and significance of virologic documentation by BAL on mortality. • Hyperglycemia associated with steroid use appears to be a strong predictor of HCoV disease progression.

Decreased cytomegalovirus (CMV)-specific immunity after hematopoietic cell transplantation (HCT) is associated with late CMV reactivation and increased mortality. Whether letermovir prophylaxis-associated reduction in viral exposure influences CMV-specific immune reconstitution is unknown. In a prospective cohort of allogeneic HCT recipients who received letermovir, we compared polyfunctional CMV-specific T-cell responses to those of controls who received PCR-guided preemptive therapy before the introduction of letermovir. Thirteen-color flow cytometry was used to assess T-cell responses at 3 months after HCT following stimulation with CMV immediate early-1 (IE-1) antigen and phosphoprotein 65 (pp65) antigens. Polyfunctionality was characterized by combinatorial polyfunctionality analysis of antigen-specific T-cell subsets. Use of letermovir and reduction of viral exposure were assessed for their association with CMV-specific T-cell immunity. Polyfunctional T-cell responses to IE-1 and pp65 were decreased in letermovir recipients and remained diminished after adjustment for donor CMV serostatus, absolute lymphocyte count, and steroid use. Among letermovir recipients, greater peak CMV DNAemia and increased viral shedding were associated with stronger CD8+ responses to pp65, whereas the CMV shedding rate was associated with greater CD4+ responses to IE-1. In summary, our study provided initial evidence that letermovir may delay CMV-specific cellular reconstitution, possibly related to decreased CMV antigen exposure. Evaluating T-cell polyfunctionality may identify patients at risk for late CMV infection after HCT.

ImportanceLong-term survivors of childhood cancer may be at elevated risk for new neurocognitive impairment and decline as they age into adulthood.ObjectiveTo determine whether aging adult childhood cancer survivors report more new-onset neurocognitive impairments compared with their siblings and to identify risk factors associated with such impairments.Design, Setting, and ParticipantsParticipants of this cohort study included adult survivors of childhood cancer from the Childhood Cancer Survivor Study and their siblings as a control group. The original cohort included survivors who received a diagnosis between January 1, 1970, and December 31, 1986, for whom longitudinal neurocognitive assessment was available. This study examined the prevalence of new-onset neurocognitive impairment between baseline (23.4 years after diagnosis) and follow-up (35.0 years after diagnosis). The analysis was performed from January 2021 to May 2022.ExposuresCancer treatment exposures were abstracted from medical records. Chronic health conditions were graded using Common Terminology Criteria for Adverse Events version 4.03.Main Outcomes and MeasuresThe primary outcome was new-onset (present at follow-up, but not present at baseline) neurocognitive impairment (defined as a score in the worst 10% of the sibling cohort). Impairment was assessed using the Childhood Cancer Survivor Study Neurocognitive questionnaire. Relative risks (RRs) and 95% CIs were used to estimate associations of neurocognitive impairment with treatment and health behaviors and conditions using generalized linear models.ResultsThe cohort comprised 2375 survivors (mean [SD] age at evaluation, 31.8 [7.5] years; 1298 women [54.6%]) of childhood cancer, including acute lymphoblastic leukemia (ALL; 1316 participants), central nervous system (CNS) tumors (488 participants), and Hodgkin lymphoma (HL; 571 participants). A total of 232 siblings (mean [SD] age at evaluation, 34.2 [8.4] years; 134 women [57.8%]) were included. Compared with siblings, a higher proportion of survivors with no impairment in memory at baseline had new-onset memory impairment at follow-up: siblings proportion, 7.8% (95% CI, 4.3%-11.4%); ALL survivors treated with chemotherapy only, 14.0% (95% CI, 10.7%-17.4%); ALL survivors treated with cranial radiation (CRT), 25.8% (95% CI, 22.6%-29.0%); CNS tumor survivors, 34.7% (95% CI, 30.0%-39.5%); and HL survivors, 16.6% (95% CI, 13.4%-19.8%). New-onset memory impairment was associated with CRT in CNS tumor survivors (RR, 1.97; 95% CI, 1.33-2.90) and alkylator chemotherapy greater than or equal to 8000 mg/m2 in ALL survivors treated without CRT (RR, 2.80; 95% CI, 1.28-6.12). Neurologic conditions mediated the impact of CRT on new-onset memory impairment in CNS survivors. Smoking, low educational attainment, and low physical activity were associated with elevated risk for new-onset memory impairment.Conclusions and RelevanceThese findings suggest that adult survivors of childhood cancer are at elevated risk for late-onset memory impairment related to modifiable risk factors identified early in survivorship.

BACKGROUND: Retrospective multicenter research using echocardiograms obtained for routine clinical care can be hampered by issues of individual center quality, thus limiting the application of post-hoc research analytics. We sought to evaluate imaging and patient characteristics associated with poorer quality of archived echocardiograms from a cohort of childhood cancer survivors. METHODS: A single blinded reviewer at a central core lab graded quality of clinical echocardiograms from 5 contributing centers focusing on images to derive 2D and M-mode fractional shortening (FS), biplane Simpson ejection fraction (EF), myocardial performance index (MPI), tissue Doppler imaging (TDI) derived velocities and global longitudinal strain (GLS). RESULTS: Of 535 studies analyzed in 102 subjects from 2004 to 2017, all measures of cardiac function could be assessed in only 7%. While FS by 2D or M-mode, MPI and septal E/E’ could be measured in >80% studies, mitral E/E’ was less consistent (69%), but better than EF (52%) and GLS (10%). At least one quality issue was identified in 66% studies, with technical issues (ex. lung artifact, poor endocardial definition) being the most common (33%). Lack of 2- and 3-chamber views was associated with the performing center. Patients < 5 years had a higher chance of apex cut-off in 4-chamber views compared to 16–35 year old (RR 1.99 (1.07–3.72), p = 0.03). Overall, for any quality issue, earlier era of echo and center were the only significant risk factors. CONCLUSION: Assessment of cardiac function using pooled multicenter archived echocardiograms was significantly limited. Efforts to standardize clinical echocardiographic protocols to include apical 2- and 3-chamber views and TDI will improve the ability to quantitate LV function.

Childhood cancer survivors treated with radiation therapy (RT) and osteotoxic chemotherapies are at increased risk for fractures. However, understanding of how genetic and clinical susceptibility factors jointly contribute to fracture risk among survivors is limited. To address this gap, we conducted genome-wide association studies of fracture risk after cancer diagnosis in 2,453 participants of European ancestry from the Childhood Cancer Survivor Study (CCSS) with 930 incident fractures using Cox regression models (i.e., time-to-event analysis) and prioritized sex- and treatment-stratified genetic associations. We performed replication analyses in 1,417 survivors of European ancestry with 652 incident fractures from the St. Jude Lifetime Cohort Study (SJLIFE). In discovery, we identified a genome-wide significant (P36 Gray only: HR=3.79, 95% CI: 1.95–7.34, P=8.2×10(−5)). These head/neck RT-specific HAGHL SNP effects were replicated in female SJLIFE survivors. In silico bioinformatics analyses suggest these fracture risk alleles regulate HAGHL gene expression and related bone resorption pathways. Genetic risk profiles integrating this locus may help identify female survivors who would benefit from targeted interventions to reduce fracture risk.

Long-term survivors of childhood Hodgkin lymphoma (HL) experience a high burden of chronic health morbidities. Correlates of neurocognitive and psychosocial morbidity have not been well established. A total of 1760 survivors of HL (mean ± SD age, 37.5 ± 6.0 years; time since diagnosis, 23.6 ± 4.7 years; 52.1% female) and 3180 siblings (mean age, 33.2 ± 8.5 years; 54.5% female) completed cross-sectional surveys assessing neurocognitive function, emotional distress, quality of life, social attainment, smoking, and physical activity. Treatment exposures were abstracted from medical records. Chronic health conditions were graded according to the National Cancer Institute’s Common Terminology Criteria for Adverse Events version 4.3 (1 = mild, 2 = moderate, 3 = severe/disabling, and 4 = life-threatening). Multivariable analyses, adjusted for age, sex, and race, estimated relative risk (RR) of impairment in survivors vs siblings and, among survivors, risk of impairment associated with demographic, clinical, treatment, and grade 2 or higher chronic health conditions. Compared with siblings, survivors had significantly higher risk (all, P < .05) of neurocognitive impairment (eg, memory, 8.1% vs 5.7%), anxiety (7.0% vs 5.4%), depression (9.1% vs 7%), unemployment (9.6% vs 4.4%), and impaired physical/mental quality of life (eg, physical function, 11.2% vs 3.0%). Smoking was associated with a higher risk of impairment in task efficiency (RR, 1.56; 95% confidence interval [CI], 1.02-2.39), emotional regulation (RR, 1.84; 95% CI, 1.35-2.49), anxiety (RR, 2.43; 95% CI, 1.51-3.93), and depression (RR, 2.73; 95% CI, 1.85-4.04). Meeting the exercise guidelines of the Centers for Disease Control and Prevention was associated with a lower risk of impairment in task efficiency (RR, 0.70; 95% CI, 0.52-0.95), organization (RR, 0.60; 95% CI, 0.45-0.80), depression (RR, 0.66; 95% CI, 0.48-0.92), and multiple quality of life domains. Cardiovascular and neurologic conditions were associated with impairment in nearly all domains. Survivors of HL are at elevated risk for neurocognitive and psychosocial impairment, and risk is associated with modifiable factors that provide targets for interventions to improve long-term functional outcomes.

BACKGROUND: Some respiratory viruses have been evaluated for the association between viral burden and respiratory disease progression in hematopoietic cell transplant (HCT) recipients, and no significant association has been reported. OBJECTIVES: To assess whether initial viral burden of respiratory viruses predicts risk of progression to lower respiratory tract infection (LRTI) in among adult allogeneic HCT recipients who presented with upper respiratory tract infection (URTI) with 12 viruses in the PCR era. STUDY DESIGN: We reviewed adult allogeneic HCT recipients (4/2008–9/2018) who presented with their first symptomatic respiratory viral infection following transplantation at the Fred Hutchinson Cancer Research Center and the Seattle Cancer Care Alliance. Cox proportional hazards models were used to investigate whether viral burden as measured by initial Ct values at the diagnosis of URTI is associated with progression to LRTI within 90 days for each virus, treating death as a competing risk. RESULTS: Among 2,148 adult HCT recipients during the study periods, 1,102 episodes of URTI met the study inclusion criteria. Higher viral burden (lower Ct value) were associated with an increased risk of progression to LRTI for influenza after adjusting for immunodeficiency scoring index and initiation of antiviral therapy, respectively. The association between viral burden and progression to LRTI was not found for other viruses. CONCLUSIONS: Our findings suggest that routine reporting of viral burden in current molecular diagnostic platforms may be beneficial. Further studies are needed to investigate the impact of viral burden on LRTI in other populations including pediatric HCT recipients.

PURPOSE Survivors of childhood cancer treated with anthracyclines and/or chest-directed radiation are at increased risk for heart failure (HF). The International Late Effects of Childhood Cancer Guideline Harmonization Group (IGHG) recommends risk-based screening echocardiograms, but evidence supporting its frequency and cost-effectiveness is limited. PATIENTS AND METHODS Using the Childhood Cancer Survivor Study and St Jude Lifetime Cohort, we developed a microsimulation model of the clinical course of HF. We estimated long-term health outcomes and economic impact of screening according to IGHG-defined risk groups (low [doxorubicin-equivalent anthracycline dose of 1-99 mg/m2 and/or radiotherapy < 15 Gy], moderate [100 to < 250 mg/m2 or 15 to < 35 Gy], or high [≥ 250 mg/m2 or ≥ 35 Gy or both ≥ 100 mg/m2 and ≥ 15 Gy]). We compared 1-, 2-, 5-, and 10-year interval-based screening with no screening. Screening performance and treatment effectiveness were estimated based on published studies. Costs and quality-of-life weights were based on national averages and published reports. Outcomes included lifetime HF risk, quality-adjusted life-years (QALYs), lifetime costs, and incremental cost-effectiveness ratios (ICERs). Strategies with ICERs < $100,000 per QALY gained were considered cost-effective. RESULTS Among the IGHG risk groups, cumulative lifetime risks of HF without screening were 36.7% (high risk), 24.7% (moderate risk), and 16.9% (low risk). Routine screening reduced this risk by 4% to 11%, depending on frequency. Screening every 2, 5, and 10 years was cost-effective for high-risk survivors, and every 5 and 10 years for moderate-risk survivors. In contrast, ICERs were > $175,000 per QALY gained for all strategies for low-risk survivors, representing approximately 40% of those for whom screening is currently recommended. CONCLUSION Our findings suggest that refinement of recommended screening strategies for IGHG high- and low-risk survivors is needed, including careful reconsideration of discontinuing asymptomatic left ventricular dysfunction and HF screening in low-risk survivors.

OBJECTIVE To delineate the impact of treatment exposures and chronic health conditions on psychological, educational, and social outcomes in adolescent survivors of Wilms tumor. METHODS Parent reports from the Childhood Cancer Survivor Study were analyzed for 666 adolescent survivors of Wilms tumor and 698 adolescent siblings. Adjusting for race and household income, survivors were compared to siblings on the Behavior Problems Index and educational outcomes. Multivariable modified Poisson regression estimated relative risks (RR) for therapeutic exposures and chronic health conditions (CTCAE 4.03 graded) among survivors, adjusting for sex, race, income, and age at diagnosis. RESULTS Compared to siblings, adolescent survivors of Wilms tumor were more likely to take psychoactive medication (9.4% vs. 5.1%, p < 0.001) and utilize special education services (25.5% vs. 12.6%, p < 0.001) but did not differ significantly in emotional and behavioral problems. Survivors were less likely to be friendless (7.2% vs. 10.1%, p = 0.04) but were more likely to have difficulty getting along with friends (14.5% vs. 7.8%, p < 0.001). Among survivors, use of special education services was associated with abdomen plus chest radiation (RR = 1.98, CI:1.18-3.34). Those with grade 2-4 cardiovascular conditions had higher risk for anxiety/depression (RR = 1.95, CI:1.19-3.19), headstrong behaviors (RR = 1.91, CI:1.26-2.89), and inattention (RR = 1.56, CI:1.02-2.40). CONCLUSIONS Adolescent survivors of Wilms tumor were similar to siblings with respect to mental health concerns overall but were more likely to require special education. Monitoring of psychosocial and academic problems through adolescence is warranted, especially among those treated with radiation to the abdomen plus chest or with cardiac conditions.

PURPOSE This study compared the measurement properties for multiple modes of survey administration, including postal mail, telephone interview, and Web-based completion of patient-reported outcomes (PROs) among survivors of childhood cancer. METHODS The population included 6,974 adult survivors of childhood cancer in the Childhood Cancer Survivor Study who completed the Brief Symptom Inventory-18 (BSI-18), which measured anxiety, depression, and somatization symptoms. Scale reliability, construct validity, and known-groups validity related to health status were tested for each mode of completion. The multiple indicators and multiple causes technique was used to identify differential item functioning (DIF) for the BSI-18 items that responded through a specific survey mode. The impact of the administration mode was tested by comparing differences in BSI-18 scores between the modes accounting for DIF effects. RESULTS Of the respondents, 58%, 27%, and 15% completed postal mail, Web-based, and telephone surveys, respectively. Survivors who were male; had lower education, lower household income, or poorer health status; or were treated with cranial radiotherapy were more likely to complete a telephone-based survey compared with either a postal mail or Web-based survey (all P < .05). Scale reliability and validity were equivalent across the 3 survey options. One, 2, and 5 items from the anxiety, depression, and somatization domains, respectively, were identified as having significant DIF among survivors who responded by telephone ( P < .05). However, estimated BSI-18 domain scores, especially depression and anxiety, between modes did not differ after accounting for DIF effects. CONCLUSION Certain survivor characteristics were associated with choosing a specific mode for PRO survey completion. However, measurement properties among these modes were equivalent, and the impact of using a specific mode on scores was minimal.

PURPOSE Radiotherapy for childhood cancer is associated with elevated subsequent neoplasm (SN) risk, but the contribution of rare variants in DNA damage response and radiation sensitivity genes to SN risk is unknown. PATIENTS AND METHODS We conducted whole-exome sequencing in a cohort of childhood cancer survivors originally diagnosed during 1970 to 1986 (mean follow-up, 32.7 years), with reconstruction of doses to body regions from radiotherapy records. We identified patients who developed SN types previously reported to be related to radiotherapy (RT-SNs; eg, basal cell carcinoma [BCC], breast cancer, meningioma, thyroid cancer, sarcoma) and matched controls (sex, childhood cancer type/diagnosis, age, SN location, radiation dose, survival). Conditional logistic regression assessed SN risk associated with potentially protein-damaging rare variants (SnpEff, ClinVar) in 476 DNA damage response or radiation sensitivity genes with exact permutation-based P values using a Bonferroni-corrected significance threshold of P < 8.06 × 10−5. RESULTS Among 5,105 childhood cancer survivors of European descent, 1,108 (21.7%) developed at least 1 RT-SN. Out-of-field RT-SN risk, excluding BCC, was associated with homologous recombination repair (HRR) gene variants (patient cases, 23.2%; controls, 10.8%; odds ratio [OR], 2.6; 95% CI, 1.7 to 3.9; P = 4.79 × 10−5), most notably but nonsignificantly for FANCM (patient cases, 4.0%; matched controls, 0.6%; P = 9.64 × 10−5). HRR variants were not associated with likely in/near-field RT-SNs, excluding BCC (patient cases, 12.7%; matched controls, 12.9%; P = .92). Irrespective of radiation dose, risk for RT-SNs was also associated with EXO1 variants (patient cases, 1.8%; controls, 0.4%; P = 3.31 × 10−5), another gene implicated in DNA double-strand break repair. CONCLUSION In this large-scale discovery study, we identified novel associations between RT-SN risk after childhood cancer and potentially protein-damaging rare variants in genes involved in DNA double-strand break repair, particularly HRR. With replication, these results could affect screening recommendations for childhood cancer survivors and risk-benefit assessments of treatment approaches.

BACKGROUND: The internet can be a valuable tool in delivering survivorship care to hematopoietic cell transplantation (HCT) cancer survivors. We describe the reach of INSPIRE, an internet and social media-based randomized controlled trial, to address healthcare and psychosocial needs of HCT survivors. MATERIALS AND METHODS: All survivors 2–10 years after HCT for hematologic malignancy or myelodysplasia from six transplant centers in the US were approached by mail and follow-up calls. Eligible participants had access to the internet, an email address, and did not have active disease in the past two years. We used logistic regression to determine characteristics of eligible survivors who were more or less likely to enroll. RESULTS: Of 2578 eligible HCT survivors, 1065 (41%) enrolled in the study. Mean age of enrollees was 56.3 (SD=12.6; age range 19 to 89 years), 52% were male, and 94% were White. Survivors less likely to enroll included those who were male, age younger than 40, and who received an autologous transplant (all P

Background Surveillance with annual mammography and breast magnetic resonance imaging (MRI) is recommended for female survivors of childhood cancer treated with chest radiation, yet benefits, harms, and costs are uncertain. Objective To compare the benefits, harms, and cost-effectiveness of breast cancer screening strategies in childhood cancer survivors. Design Collaborative simulation modeling using 2 Cancer Intervention and Surveillance Modeling Network breast cancer models. Data sources Childhood Cancer Survivor Study and published data. Target population Women aged 20 years with a history of chest radiotherapy. Time horizon Lifetime. Perspective Payer. Intervention Annual MRI with or without mammography, starting at age 25, 30, or 35 years. Outcome measures Breast cancer deaths averted, false-positive screening results, benign biopsy results, and incremental cost-effectiveness ratios (ICERs). Results of base-case analysis Lifetime breast cancer mortality risk without screening was 10% to 11% across models. Compared with no screening, starting at age 25 years, annual mammography with MRI averted the most deaths (56% to 71%) and annual MRI (without mammography) averted 56% to 62%. Both strategies had the most screening tests, false-positive screening results, and benign biopsy results. For an ICER threshold of less than $100 000 per quality-adjusted life-year gained, screening beginning at age 30 years was preferred. Results of sensitivity analysis Assuming lower screening performance, the benefit of adding mammography to MRI increased in both models, although the conclusions about preferred starting age remained unchanged. Limitation Elevated breast cancer risk was based on survivors diagnosed with childhood cancer between 1970 and 1986. Conclusion Early initiation (at ages 25 to 30 years) of annual breast cancer screening with MRI, with or without mammography, might reduce breast cancer mortality by half or more in survivors of childhood cancer.

BackgroundSurvivors of childhood acute myeloid leukemia (AML) are vulnerable to medical late effects of treatment; however, less is known about their psychosocial outcomes. This study evaluated neurocognitive and psychosocial outcomes in long-term AML survivors treated with bone marrow transplantation (BMT) or intensive chemotherapy (IC) without BMT.MethodsAML survivors (N = 482; median age at diagnosis = 8 [range = 0-20] years; median age at evaluation = 30 [range = 18-49] years) treated with BMT (n = 183) or IC (n = 299) and sibling controls (N = 3190; median age at evaluation = 32 [range = 18-58] years) from the Childhood Cancer Survivor Study were compared on emotional distress (Brief Symptom Inventory-18), neurocognitive problems (Childhood Cancer Survivor Study Neurocognitive Questionnaire), health-related quality of life (SF-36), and social attainment. Outcomes were dichotomized (impaired vs nonimpaired) using established criteria, and relative risks (RRs) were estimated with multivariable Poisson regression, adjusted for age at evaluation and sex.ResultsAML survivors were more likely than siblings to report impairment in overall emotional (RR = 2.19, 95% confidence interval [CI] = 1.51 to 3.18), neurocognitive (RR = 2.03, 95% CI = 1.47 to 2.79), and physical quality of life (RR = 2.71, 95% CI = 1.61 to 4.56) outcomes. Survivors were at increased risk for lower education (RR = 1.15, 95% CI = 1.03 to 1.30), unemployment (RR = 1.41, 95% CI = 1.16 to 1.71), lower income (RR = 1.39, 95% CI = 1.17 to 1.65), and not being married or having a partner (RR = 1.33, 95% CI = 1.17 to 1.51). BMT-treated survivors did not differ statistically significantly from IC-treated on any outcome measure.ConclusionsAML survivors are at increased risk for psychosocial impairment compared with siblings; however, BMT does not confer additional risk for psychosocial late effects compared with treatment without BMT.

We sought to determine whether donor-derived human herpesvirus (HHV) 6B–specific CD4+ T-cell abundance is correlated with HHV-6B detection after allogeneic hematopoietic cell transplantation. We identified 33 patients who received HLA-matched, non–T-cell–depleted, myeloablative allogeneic hematopoietic cell transplantation and underwent weekly plasma polymerase chain reaction testing for HHV-6B for 100 days thereafter. We tested donor peripheral blood mononuclear cells for HHV-6B–specific CD4+ T cells. Patients with HHV-6B detection above the median peak viral load (200 copies/mL) received approximately 10-fold fewer donor-derived total or HHV-6B–specific CD4+ T cells than those with peak HHV-6B detection at ≤200 copies/mL or with no HHV-6B detection. These data suggest the importance of donor-derived immunity for controlling HHV-6B reactivation.

Background The objective of this study was to characterize the prevalence and risk of pain, pain interference, and recurrent pain in adult survivors of childhood cancer in comparison with siblings. Methods This study analyzed longitudinal data from survivors (n = 10,012; 48.7% female; median age, 31 years [range, 17-57 years]; median time since diagnosis, 23 years) and siblings (n = 3173) from the Childhood Cancer Survivor Study. Survivors were diagnosed between 1970 and 1986 at 1 of 26 participating sites. Associations between risk factors (demographics, cancer-related factors, and psychological symptoms) and pain, pain interference, and recurrent pain (5 years apart) were assessed with multinomial logistic regression. Path analyses examined cross-sectional associations between risk factors and pain outcomes. Results Twenty-nine percent of survivors reported moderate to severe pain, 20% reported moderate to extreme pain interference, and 9% reported moderate to severe recurrent pain. Female sex, a sarcoma/bone tumor diagnosis, and severe/life-threatening chronic medical conditions were associated with recurrent pain. Depression and anxiety were associated with increased risk for all pain outcomes. Poor vitality mediated the effects of anxiety on high pain and pain interference (root mean square error of approximation, 0.002). Conclusions A large proportion of adult survivors report moderate to severe pain and pain interference more than 20 years after their diagnosis. Increased screening and early intervention for pain interference and recurrent pain are warranted.

Objectives: The purpose of this study was to assess the timing of changes in serial echocardiographic parameters in pediatric cancer survivors and to evaluate their associations with cardiomyopathy development. Background: Pediatric cancer survivors undergo serial echocardiograms to screen for cardiotoxicity. It is not clear whether small longitudinal changes in functional or structural parameters over time have clinical significance. Methods: This is a multicenter, retrospective, case-control study of ≥1-year survivors following the end of cancer therapy. Cardiomyopathy cases (fractional shortening [FS] ≤28% or ejection fraction [EF] ≤50% on ≥2 occasions) were matched to control subjects (FS ≥30%, EF ≥55%, not on cardiac medications) by cumulative anthracycline and chest radiation dose, follow-up duration, and age at diagnosis. Digitally archived clinical surveillance echocardiograms were quantified in a central core laboratory, blinded to patient characteristics. Using mixed models with interaction terms between time and case status, we estimated the least square mean differences of 2-dimensional, M-mode, pulsed wave Doppler, and tissue Doppler imaging–derived parameters over time between cases and control subjects. Results: We identified 50 matched case-control pairs from 5 centers. Analysis of 412 echocardiograms (cases, n = 181; control subjects, n = 231) determined that indices of left ventricular systolic function (FS, biplane EF), diastolic function (mitral E/A ratio), and left ventricular size (end-diastolic dimension z-scores) were significantly different between cases and control subjects, even 4 years prior to the development of cardiomyopathy. Conclusions: Longitudinal changes in cardiac functional parameters can occur relatively early in pediatric cancer survivors and are associated with the development of cardiomyopathy.

BK polyomavirus (BKPyV) has been associated with hemorrhagic cystitis (HC) after allogeneic hematopoietic cell transplantation (HCT), but the natural history of HC and factors associated with the clinical course are incompletely understood. We retrospectively analyzed allogeneic HCT patients transplanted from 2007-2017 who presented after platelet engraftment or after day 28 post-HCT with BKPyV-associated HC (BKPyV-HC), which was defined as a positive urine BKPyV PCR, ≥1 plasma BKPyV viral load result, and macroscopic hematuria (Bedi grade ≥2). Factors associated with resolution of macroscopic hematuria and resolution of all cystitis symptoms within 90 days after HC diagnosis were investigated in multivariable models. In 128 patients with BKPyV-HC, the median times from diagnosis to resolution of all symptoms, macroscopic hematuria, and urinary clots (present in 55% [71/128]) were 24 days (15-44), 17 days (10-30), and 14 days (5-26), respectively. Ninety percent of patients had BKPyV viremia at the onset of HC with a median viral load of 1850 copies/mL (interquartile range, 240-8550). In multivariable models, high plasma viral load (≥10 000 copies/mL) and cytopenias at the beginning of BKPyV-HC were significantly associated with longer macroscopic hematuria and cystitis symptoms. Use of cidofovir was not associated with shorter duration of illness. In conclusion, BKPyV-HC after allogeneic HCT is characterized by prolonged and severe symptoms and requires improved management strategies. High-grade viremia and cytopenias were associated with a longer duration of BKPyV-associated HC. Accurate descriptions of disease and factors associated with prolonged recovery will inform end points of future clinical trials.
