OBJECTIVE: We sought to assess the feasibility, reproducibility, and accuracy of conventional and newer echocardiographic measures of right ventricular (RV) systolic function in adolescent and young adult childhood cancer survivors treated with anthracyclines.
METHODS: Echocardiography and cardiac magnetic resonance imaging (CMR) were acquired ≤60 days apart in prospectively recruited survivors and RV functional measures were quantitated by blinded observers. Repeat quantitation was performed in a subset to evaluate reproducibility. For each echocardiographic measure, Spearman correlations with CMR measures were calculated, and values in participants with CMR RV ejection fraction (RVEF) ≥48% and RVEF <48% were compared using two sample Wilcoxon rank-sum tests.
RESULTS: Among 58 participants, mean age was 18.2 years (range 13.1-25.2) and five participants had CMR RVEF <48%. Intra- and inter-observer coefficients of variation were 8.2%-10.1% and 10.5%-12.0% for adjusted automated strain measures, and 5.2%-8.7% and 2.7% for 3D RVEF, respectively. No echocardiographic measures were significantly correlated with CMR RVEF; only tricuspid annular plane systolic excursion was correlated with CMR RV stroke volume (r = .392, p = .003). Participants with RV dysfunction had worse automated global longitudinal strain (-20.3% vs. -23.9%, p = .007) and free wall longitudinal strain (-23.7% vs. -26.7%, p = .09).
CONCLUSIONS: Echocardiographic strain and 3D RV function measurements were feasible and reproducible in at-risk childhood cancer survivors. Although not associated with CMR RVEF in this population with predominantly normal RV function, automated strain measurements were more abnormal in participants with RV dysfunction, suggesting potential clinical utility of these measures.

UNASSIGNED: Cardiovascular (CV) diseases are a cause of increased long-term morbidity and mortality in childhood cancer survivors (CCSs) treated with anthracyclines. These drugs may affect not only the heart, but also the vascular system. Left ventricular-arterial coupling (LVAC) represents a reliable parameter of altered ventricular and vascular performance, with validated prognostic value and never investigated in this setting. Aim of this study was to assess, in CCSs and matched controls, LVAC changes, performed with different echocardiographic modalities, and their relationship with endothelial function.
UNASSIGNED: Twenty survivors treated with anthracyclines for childhood malignancies and a matched control group of 20 healthy subjects were enrolled. Arterial elastance (Ea), end-systolic elastance (Ees), Ea/Ees ratio, as well as three-dimensional (3D) LVAC (assessed by measurement of End Systolic Volume [ESV]/Stroke Volume [SV] ratio) were performed at rest. Endothelial function was evaluated by measurement of flow-mediated dilatation (FMD) of the brachial artery.
UNASSIGNED: 3D SV and 3D ESV/SV ratio resulted respectively significantly lower and higher in CCSs than in controls, while Ea, Ees and Ea/Ees ratio were not different among groups. A positive correlation between 3D ESV/SV ratio and cumulative anthracycline doses, as well as with time after drug exposure were also found. Mean FMD was similar in CCSs and controls (8.45 ± 1.79 versus 9.41 ± 3.41, p = 0.34).
UNASSIGNED: In conclusion, conventional LVAC parameters were not shown to be significantly different between CCSs and controls; however, 3D SV and LVAC were significantly impaired in our population. In these patients, endothelial function was comparable to controls. Larger validation studies are therefore needed.

Anthracyclines have significantly improved the survival of children with malignant tumors, but the associated cardiotoxicity, an effect now under the purview of pediatric cardio-oncology, due to its cumulative and irreversible effects on the heart, limits their clinical application. A systematic screening and risk stratification approach provides the opportunity for early identification and intervention to mitigate, reverse, or prevent myocardial injury, remodeling, and dysfunction associated with anthracyclines. This review summarizes the risk factors, surveillance indexes, and preventive strategies of anthracycline-related cardiotoxicity to improve the safety and efficacy of anthracyclines.

UNASSIGNED: Childhood Cancer Survivors (CCSs) are more likely to report sexual dysfunction than people without cancer history. Sexual functioning encompasses more than just sexual dysfunction. The scarcity of information regarding the status and influencing factors of sexual functioning in CCSs, hampers to devise suitable screening or interventions. This review aims to summarize research progress on sexual functioning and associated factors among CCSs.
UNASSIGNED: This review protocol is registered in PROSPERO(CRD42023427939) and performed according to PRISMA guidelines. From inception to November 15, 2023, a comprehensive search was conducted in PubMed, EMBASE, CINAHL, Web of Science, SCOPUS, PsycINFO, CNKI Database, Wanfang of Chinese Database, SinoMed Database and Cochrane Library on sexual functioning and childhood cancer survivors. Inclusion criteria were English or Chinese studies focusing on sexual functioning and related factors of cancer survivors, who diagnosed with cancer before 18 years old, and were adult and disease-free when participating in the study. Studies were excluded if the focus was on adult cancer patients or without age information.
UNASSIGNED: 395 records were retrieved, and 22 studies were finally included in this review. Results suggest that CCSs experience a substantial burden of sexual issues, including delayed psychosexual development, low satisfaction, and high prevalence of dysfunction. Underlying factors related to sexual functioning of CCSs were identified, including demographic, cancer treatment-related, psychological, and physiological factors. The historical change in research on sexual functioning was summarized.
UNASSIGNED: Research on sexual functioning among CCSs is limited. The extent to which cancer and related treatments affect sexual functioning remains largely unknown. The relationships between various factors and mechanisms underlying sexual functioning need to be confirmed by more rigorous studies to enable effective interventions to be developed.
UNASSIGNED: None.

BACKGROUND: Interpersonal communication is a crucial component of the cancer experience that can contribute to managing cancer care and improving cancer survivors\' and caregivers\' quality of life. Cultural and contextual factors may impact Hispanic childhood cancer survivor (CCS) and parent caregiver relationships and communication. This study sought to describe the healthcare communication experiences of Hispanic parents with CCS, families, and medical providers.
METHODS: We conducted 15 semi-structured interviews with Hispanic caregivers from a safety-net hospital in Los Angeles County. Interviews were conducted in English and Spanish, audio-recorded and professionally transcribed, and analyzed using a thematic approach.
RESULTS: Caregivers shared the importance and impact of medical communication when exploring the \"first big talk\" of the diagnosis, uncertainty about treatment, navigating multiple providers, therapeutic communication (i.e., providing emotional reassurance), and current and lingering effects of cancer. All caregivers shared \"good communication\" experiences, while others shared various barriers to communication, including a lack of understanding of the cancer diagnosis and caregiver experience, psychological challenges impacting communication, cultural and language differences, physical factors that limit communication, and young age of child impacting communication with caregivers.
CONCLUSIONS: Our findings suggest that a strong interpersonal communication skill set for clinicians can contribute to managing cancer care and improving caregivers\' psychological adjustment.

BACKGROUND: Data on ovarian function in neuroblastoma survivors are limited. We sought to determine the prevalence of ovarian dysfunction in a cohort of high-risk neuroblastoma survivors and compare outcomes among survivors treated with and without autologous stem cell rescue (ASCR) preceded by myeloablative chemotherapy.
METHODS: Retrospective review of female survivors of high-risk neuroblastoma ≥5 years from diagnosis, diagnosed between 1982 and 2014, and followed in a tertiary cancer center. Participants were divided into two groups: individuals treated with conventional chemotherapy ± radiation (\"non-ASCR\") (n = 32) or with chemotherapy ± radiation followed by myeloablative chemotherapy with ASCR (\"ASCR\") (n = 51). Ovarian dysfunction was defined as follicle-stimulating hormone ≥15 mU/mL, while premature ovarian insufficiency (POI) was defined as persistent ovarian dysfunction requiring hormone replacement therapy. Poisson models were used to determine prevalence ratios of ovarian dysfunction and POI.
RESULTS: Among 83 females (median attained age: 19 years [range, 10-36]; median follow-up: 15 years [range, 7-36]), 49 (59%) had ovarian dysfunction, and 34 (41%) developed POI. Survivors treated with ASCR were 3.2-fold more likely to develop ovarian dysfunction (95% CI: 1.8-6.0; p < 0.001) and 4.5-fold more likely to develop POI (95% CI: 1.7-11.7; p = 0.002) when compared with those treated with conventional chemotherapy, after adjusting for attained age. Two participants in the non-ASCR group and six in the ASCR group achieved at least one spontaneous pregnancy.
CONCLUSIONS: Ovarian dysfunction is prevalent in female high-risk neuroblastoma survivors, especially after ASCR. Longitudinal follow-up of larger cohorts is needed to inform counseling about the risk of impaired ovarian function after neuroblastoma therapy.

UNASSIGNED: Cancer therapies predispose childhood cancer survivors to various treatment-related late effects, which contribute to a higher symptom burden, chronic health conditions (CHCs), and premature mortality. Regular monitoring of symptoms between clinic visits is useful for timely medical consultation and interventions that can improve quality of life (QOL). The Health Share Study aims to utilize mHealth to collect patient-generated health data (PGHD; daily symptoms, momentary physical health status) and develop survivor-specific risk prediction scores for mitigating adverse health outcomes including poor QOL and emergency room admissions. These personalized risk scores will be integrated into the hospital-based electronic health record (EHR) system to facilitate clinician communications with survivors for timely management of late effects.
UNASSIGNED: This prospective study will recruit 600 adult survivors of childhood cancer from the St. Jude Lifetime Cohort study. Data collection include 20 daily symptoms via a smartphone, objective physical health data (physical activity intensity, sleep performance, and biometric data including resting heart rate, heart rate variability, oxygen saturation, and physical stress) via a wearable activity monitor, patient-reported outcomes (poor QOL, unplanned healthcare utilization) via a smartphone, and clinically ascertained outcomes (physical performance deficits, onset of/worsening CHCs) assessed in the survivorship clinic. Participants will complete health surveys and physical/functional assessments in the clinic at baseline, 2) report daily symptoms, wear an activity monitor, measure blood pressure at home over 4 months, and 3) complete health surveys and physical/functional assessments in the clinic 1 and 2 years from the baseline. Socio-demographic and clinical data abstracted from the EHR will be included in the analysis. We will invite 20 cancer survivors to investigate suitable formats to display predicted risk information on a dashboard and 10 clinicians to suggest evidence-based risk management strategies for adverse health outcomes.
UNASSIGNED: Machine and statistical learning will be used in prediction modeling. Both approaches can handle a large number of predictors, including longitudinal patterns of daily symptoms/other PGHD, along with cancer treatments and socio-demographics.
UNASSIGNED: The individualized risk prediction scores and added communications between providers and survivors have the potential to improve survivorship care and outcomes by identifying early clinical presentations of adverse events.

UNASSIGNED: Childhood cancer survivors at risk for heart failure undergo lifelong echocardiographic surveillance. Previous studies reported the limited diagnostic accuracy of N-terminal pro-B-type natriuretic peptide (NT-proBNP) and high-sensitivity cardiac troponin T (hs-cTnT) in detecting left ventricular (LV) dysfunction. However, potential enhanced diagnostic accuracy through the combination of biomarkers and clinical characteristics has been suggested.
UNASSIGNED: The aim of this study was to develop and internally validate a diagnostic model that combines cardiac biomarkers with clinical characteristics for effectively ruling in or ruling out LV dysfunction in childhood cancer survivors.
UNASSIGNED: A multicenter cross-sectional study included 1,334 survivors (median age 34.2 years) and 278 siblings (median age 36.8 years). Logistic regression models were developed and validated through bootstrapping, combining biomarkers with clinical characteristics.
UNASSIGNED: Abnormal NT-proBNP levels were observed in 22.1% of survivors compared with 5.4% of siblings, whereas hs-cTnT levels exceeding 10 ng/L were uncommon in both survivors (5.9%) and siblings (5.0%). The diagnostic models demonstrated improvement upon the addition of NT-proBNP and hs-cTnT to clinical characteristics, resulting in an increased C statistic from 0.69 to 0.73 for LV ejection fraction (LVEF) <50% and a more accurate prediction of more severe LV dysfunction, with the C statistic increasing from 0.80 to 0.86 for LVEF <45%. For LVEF <50% (prevalence 10.9%), 16.9% of survivors could be effectively ruled out with high sensitivity (95.4%; 95% CI: 90.4%-99.3%) and negative predictive value (97.5%; 95% CI: 94.6%-99.7%). Similarly, for LVEF <45% (prevalence 3.4%), 53.0% of survivors could be ruled out with moderate to high sensitivity (91.1%; 95% CI: 79.2%-100%) and high negative predictive value (99.4%; 95% CI: 98.7%-100%).
UNASSIGNED: The biomarker-based diagnostic model proves effective in ruling out LV dysfunction, offering the potential to minimize unnecessary surveillance echocardiography in childhood cancer survivors. External validation is essential to confirm these findings. (Early Detection of Cardiac Dysfunction in Childhood Cancer Survivors; A DCOG LATER Study; https://onderzoekmetmensen.nl/nl/trial/23641).

OBJECTIVE: In Germany, children diagnosed with cancer survive their initial disease in more than 80%, and the majority will become long-term survivors. Around the age of 18, survivors are transferred to adult healthcare. The transition can be a critical period in the process of care at which many childhood cancer survivors discontinue to participate in regular follow-up care. Hence, the objective of the paper was to explore (a) survivors\' attitudes towards pediatric follow-up care and (b) their concerns regarding the transition process to draw conclusions for optimizing pediatric care and transition processes.
METHODS: We conducted semi-structured interviews with 21 adolescent childhood cancer survivors between the ages of 14 and 20. The survivors were recruited via a pediatric oncology department of a university hospital in Germany. Based on the principles of qualitative content analysis, a deductive-inductive method according to Kuckartz was applied.
RESULTS: Based on the interview guide and derived from the exploratory research questions, two key categories were generated: (a) Survivors\' attitudes towards pediatric follow-up care, which encompasses all formal and emotional aspects of survivors regarding follow-up care, and (b) their concerns regarding transition from pediatric to adult healthcare, where hindering and facilitating factors for a successful transition occur. Our results show high satisfaction among survivors with follow-up care. Nevertheless, they wish to be more integrated into processes and the organization of their follow-up care. Most adolescent survivors do not feel ready for transition.
CONCLUSIONS: The integration of survivors into the organization processes and routines, and the promotion of emotional detachment from pediatric health care professionals (HCPs) are important to reduce concerns and uncertainties of adolescent survivors regarding the transition process and to promote subjective readiness for transition. To gain confidence in the adult healthcare, it is crucial to provide tailored education depending on individual requirements and needs and to build trusting relationships between survivors and adult HCPs.

BACKGROUND: Childhood cancer survivors (CCSs) face an increased risk of cardiovascular disease (CVD). This systematic review aims to provide the first synthesis of observational and interventional studies on the relationship between diet and cardiovascular health in CCSs.
METHODS: A comprehensive search was conducted for studies published between 1990 and July 2023 in PubMed, MEDLINE, CINAHL, Child Development & Adolescent Studies, and Cochrane Library. Eligible studies included observational and interventional studies examining the associations or effects of dietary factors on CVD incidence, cardiac dysfunction, or CVD risk factors in CCSs diagnosed before age 25 years.
RESULTS: Ten studies met the inclusion criteria (nine observational and one interventional). Collectively, they comprised 3485 CCSs (male, 1734; female, 1751). The outcomes examined across observational studies included characteristics of obesity, diabetes biomarkers, hypertension indicators, dyslipidaemia biomarkers, and metabolic syndrome. The evidence suggested that greater adherence to healthy diets was associated with lower body mass index, blood pressure, glucose, and triglycerides and higher high-density lipoprotein cholesterol. The 12-week lifestyle intervention study in childhood leukaemia survivors found no impact on obesity indicators.
CONCLUSIONS: The review results indicate the potentially protective effects of healthy diets. However, the available research remains preliminary and limited, underscoring the need for more rigorous, adequately powered studies.
