Show moreBackgroundDexamethasone is important in the treatment for pediatric acute lymphoblastic leukemia (ALL) but induces muscle atrophy with negative consequences for muscle mass, muscle strength, and functional abilities. The aim of this study was to establish the effect of a dexamethasone course on sarcopenia and physical frailty in children with ALL, and to explore prognostic factors.MethodsPatients with ALL aged 3-18 years were included during maintenance therapy. Patients had a sarcopenia/frailty assessment on the first day of (T1) and on the day after (T2) a 5-day dexamethasone course. Sarcopenia was defined as low muscle strength in combination with low muscle mass. Prefrailty and frailty were defined as having two or >= three of the following components, respectively: low muscle mass, low muscle strength, fatigue, slow walking speed, and low physical activity. Chi-squared and paired t-tests were used to assess differences between T1 and T2. Logistic regression models were estimated to explore patient- and therapy-related prognostic factors for frailty on T2.ResultsWe included 105 patients, 61% were boys. Median age was 5.3 years (range: 3-18.8). At T1, sarcopenia, prefrailty, and frailty were observed in respectively 2.8%, 23.5%, and 4.2% of patients. At T2, the amount of patients with frailty had increased to 17.7% (p = 0.002), whereas the number of patients with sarcopenia and prefrailty remained similar. Higher ASMM (odds ratio [OR]: 0.49, 95% CI: 0.28-0.83), stronger handgrip strength (OR: 0.41, 95% CI: 0.22-0.77) and more physical activity minutes per day (OR: 0.98, 95% CI: 0.96-0.99) decreased the risk of frailty at T2. Slower walking performance (OR: 2, 95% CI: 1.2-3.39) increased the risk. Fatigue levels at T1 were not associated with frailty at T2.ConclusionPhysical frailty increased strikingly after a 5-days dexamethasone course in children with ALL. Children with poor physical state at start of the dexamethasone course were more likely to be frail after the course.Dexamethasone is important in the treatment for pediatric acute lymphoblastic leukemia (ALL) but induces muscle atrophy. After a 5-day dexamethasone course. Physical frailty increased with 13.5% in pediatric ALL patients. A poorer physical state at start of a dexamethasone course (lower muscle mass, muscle strength, or slower movement ability) was prognostic for developing frailty after a dexamethasone course.image Show less

Show moreBackground. Childhood cancer survivors (CCS) who received radiotherapy involving the spleen or total body irradiation (TBI) might be at risk for splenic dysfunction. A comprehensive screening test for examining splenic dysfunction is lacking. Objective. We investigated whether IgM memory B-cells could be used to assess splenic dysfunction in CCS who received a splenectomy, radiotherapy involving the spleen, or TBI. Methods. All CCS were enrolled from the DCCSS-LATER cohort. We analyzed differences in IgM memory B-cells and Howell-Jolly bodies (HJB) in CCS who had a splenectomy (n = 9), received radiotherapy involving the spleen (n = 36), or TBI (n = 15). IgM memory B-cells < 9 cells/mu L was defined as abnormal. Results. We observed a higher median number of IgM memory B-cells in CCS who received radiotherapy involving the spleen (31 cells/mu L, p=0.06) or TBI (55 cells/mu L, p = 0.03) compared to CCS who received splenectomy (20 cells/mu L). However, only two CCS had IgM memory B-cells below the lower limit of normal. No difference in IgM memory B-cells was observed between CCS with HJB present and absent (35 cells/mu L vs. 44 cells/mu L). Conclusion. Although the number of IgM memory B-cells differed between splenectomized CCS and CCS who received radiotherapy involving the spleen or TBI, only two CCS showed abnormal values. Therefore, this assessment cannot be used to screen for splenic dysfunction. Show less

Show moreBACKGROUND Childhood cancer survivors (CCS) are at risk for cardiotoxicity.OBJECTIVES We sought to assess how cardiac dysfunction measurements in CCS overlap and are differentially influenced by risk factors.METHODS This cross-sectional Dutch Childhood Cancer Survivor Study evaluated echocardiograms of 1,397 $5-year CCS and 277 siblings. Of CCS, n = 1,254 received cardiotoxic (anthracyclines/mitoxantrone/radiotherapy involving the heart region [RTheart]) and n = 143 received potentially cardiotoxic (cyclophosphamide, ifosfamide, or vincristine) therapy. We assessed demographic, treatment-related, and traditional cardiovascular risk factors for cardiac dysfunction using multivariable logistic regression.RESULTS CCS were a median of 26.7 years after diagnosis; 49% were women. Abnormal left ventricular ejection fraction (LVEF) (defined as < 52% in men, < 54% in women) occurred most commonly in CCS treated with anthracyclines and RTheart combined (38%). Age/sex-specific abnormal global longitudinal strain (GLS) occurred most commonly in CCS treated with RTheart, either with (41%) or without (38%) anthracyclines. Of CCS with normal LVEF, 20.2% showed abnormal GLS. Diastolic dysfunction grade $II was rare. Abnormal LVEF was mainly associated with female sex, anthracycline dose, and only in women, RTheart dose. Abnormal GLS was associated with female sex, RTheart dose, diastolic blood pressure, and only in women, anthracycline dose. Cyclophosphamide, ifosfamide, and vincristine were not associated with LVEF or GLS. Compared with siblings, CCS showed higher risk of abnormal LVEF (OR: 2.9; 95% CI: 1.4-6.6) and GLS (OR: 2.1; 95% CI: 1.2-3.7), independent of (potentially) cardiotoxic treatment-related and cardiovascular risk factors.CONCLUSIONS Abnormal LVEF and GLS constitute complementary measures of systolic dysfunction among longterm CCS. Their diagnostic value may differ according to cardiotoxic exposures. Also, CCS have residual, unexplained risk of cardiac dysfunction.

Show moreObjectiveTo describe psychosocial outcomes among adult siblings of very long-term childhood cancer survivors (CCS), to compare these outcomes to reference populations and to identify factors associated with siblings' psychosocial outcomes. MethodsSiblings of survivors (diagnosed <18 years old, between 1963 and 2001, >5 years since diagnosis) of the Dutch Childhood Cancer Survivor Study DCCSS-LATER cohort were invited to complete questionnaires on HRQoL (TNO-AZL Questionnaire for Adult's HRQoL), anxiety/depression (Hospital Anxiety and Depression Scale), post-traumatic stress (Self-Rating Scale for Post-traumatic Stress Disorder), self-esteem (Rosenberg Self-Esteem Scale) and benefit and burden (Benefit and Burden Scale for Children). Outcomes were compared to a reference group if available, using Mann-Whitney U and chi-Square tests. Associations of siblings' sociodemographic and CCS' cancer-related characteristics with the outcomes were assessed with mixed model analysis. ResultsFive hundred five siblings (response rate 34%, 64% female, mean age 37.5, mean time since diagnosis 29.5) of 412 CCS participated. Siblings had comparable HRQoL, anxiety and self-esteem to references with no or small differences (r = 0.08-0.15, p < 0.05) and less depression. Proportions of symptomatic PTSD were very small (0.4%-0.6%). Effect sizes of associations of siblings' sociodemographic and CCS cancer-related characteristics were mostly small to medium (& beta; = 0.19-0.67, p < 0.05) and no clear trend was found in the studied associated factors for worse outcomes. ConclusionsOn the very long-term, siblings do not have impaired psychosocial functioning compared to references. Cancer-related factors seem not to impact siblings' psychosocial functioning. Early support and education remain essential to prevent long-term consequences. Show less

Show moreObjectivesChildhood cancer may negatively impact childhood cancer survivors' (CCS) sexuality. However, this is an understudied research area. We aimed to describe the psychosexual development, sexual functioning and sexual satisfaction of CCS, and identify determinants for these outcomes. Secondarily, we compared the outcomes of a subsample of emerging adult CCS to the Dutch general population. MethodsFrom the Dutch Childhood Cancer Survivor Study LATER cohort (diagnosed 1963-2001), 1912 CCS (18-71 years, 50.8% male) completed questions on sexuality, psychosocial development, body perception, mental and physical health. Multivariable linear regressions were used to identify determinants. Sexuality of CCS age 18-24 (N = 243) was compared to same-aged references using binomial tests and t-tests. ResultsOne third of all CCS reported hindered sexuality due to childhood cancer, with insecure body the most often reported reason (44.8%). Older age at study, lower education, surviving central nervous system cancer, poorer mental health and negative body perception were identified as determinants for later sexual debut, worse sexual functioning and/or sexual satisfaction. CCS age 18-24 showed significantly less experience with kissing (p = 0.014), petting under clothes (p = 0.002), oral (p = 0.016) and anal sex (p = 0.032) when compared to references. No significant differences with references were found for sexual functioning and sexual satisfaction, neither among female CCS nor male CCS age 18-24. ConclusionsEmerging adult CCS reported less experience with psychosexual development, but similar sexual functioning and sexual satisfaction compared to references. We identified determinants for sexuality, which could be integrated in clinical interventions for CCS at risk for reduced sexuality. Show less

Show moreBackground: Dexamethasone is a cornerstone of paediatric acute lymphoblastic leukaemia (ALL) treatment, although it can induce serious side-effects. Our previous study suggests that children who suffer most from neurobehavioural side-effects might benefit from physiological hydrocortisone in addition to dexamethasone treatment. This study aimed to validate this finding.Methods: Our phase three, double-blind, randomised controlled trial with cross-over design included ALL patients (3-18 years) during medium-risk maintenance therapy in a national tertiary hospital between 17th May 2018 and 5th August 2020. A baseline measurement before and after a 5-day dexamethasone course was performed, whereafter 52 patients with clinically relevant neurobehavioural problems were randomised to receive an intervention during four subsequent dexamethasone courses. The intervention consisted of two courses hydrocortisone (physiological dose 10 mg/m2/d in circadian rhythm), followed by two courses placebo, or vice versa. Neurobehavioural problems were assessed before and after each course using the parent-reported Strengths and Difficulties Questionnaire (SDQ) as primary end-point. Secondary end-points were sleep problems, health-related quality of life (HRQoL), hunger feeling, and parental stress, measured with questionnaires and actigraphy. A generalised mixed model was estimated to study the intervention effect.Results: The median age was 5.5 years (range 3.0-18.8) and 61.5% were boys. The SDQ filled in by 51 primary caregivers showed no difference between hydrocortisone and placebo in reducing dexamethasone-induced neurobehavioral problems (estimated effect-2.05 (95% confidence interval (CI)-6.00-1.90). Also, no benefit from hydrocortisone compared to pla-cebo was found for reducing sleep problems, hunger, parental stress or improving HRQoL.Conclusions: Hydrocortisone, when compared to placebo, had no additional effect in redu-cing clinically relevant dexamethasone-induced neurobehavioural problems. Therefore, hy-drocortisone is not advised as standard of care for children with ALL who experience dexamethasone-induced neurobehavioural problems.

Show moreBackground: Childhood cancer survivors appear to be at increased risk of frailty and sarcopenia, but evidence on the occurrence of and high-risk groups for these aging phenotypes is scarce, especially in European survivors. The aim of this cross-sectional study was to assess the prevalence of and explore risk factors for pre-frailty, frailty, and sarcopenia in a national cohort of Dutch childhood cancer survivors diagnosed between 1963 and 2001.Methods: Eligible individuals (alive at the time of study, living in the Netherlands, age 18-45 years, and had not previously declined to participate in a late-effects study) from the Dutch Childhood Cancer Survivor Study (DCCSS-LATER) cohort were invited to take part in this cross-sectional study. We defined pre-frailty and frailty according to modified Fried criteria, and sarcopenia according to the European Working Group on Sarcopenia in Older People 2 definition. Associations between these conditions and demographic and treatment-related as well as endocrine and lifestyle-related factors were estimated with two separate multivariable logistic regression models in survivors with any frailty measurement or complete sarcopenia measurements. Findings: 3996 adult survivors of the DCCSS-LATER cohort were invited to participate in this cross-sectional study. 1993 non-participants were excluded due to lack of response or a decline to participate and 2003 (50.1%) childhood cancer survivors aged 18-45 years were included. 1114 (55.6%) participants had complete frailty measurements and 1472 (73.5%) participants had complete sarcopenia measurements. Mean age at participation was 33.1 years (SD 7.2). 1037 (51.8%) participants were male, 966 (48.2%) were female, and none were transgender. In survivors with complete frailty measurements or complete sarcopenia measurements, the percentage of pre-frailty was 20.3% (95% CI 18.0-22.7), frailty was 7.4% (6.0-9.0), and sarcopenia was 4.4% (3.5-5.6). In the models for pre-frailty, underweight (odds ratio [OR] 3.38 [95% CI 1.92-5.95]) and obesity (OR 1.67 [1.14-2.43]), cranial irradiation (OR 2.07 [1.47-2.93]), total body irradiation (OR 3.17 [1.77-5.70]), cisplatin dose of at least 600 mg/m2 (OR 3.75 [1.82-7.74]), growth hormone deficiency (OR 2.25 [1.23-4.09]), hyperthyroidism (OR 3.72 [1.63-8.47]), bone mineral density (Z score <=-1 and >-2, OR 1.80 [95% CI 1.31-2.47]; Z score <=-2, OR 3.37 [2.20-5.15]), and folic acid deficiency (OR 1.87 [1.31-2.68]) were considered significant. For frailty, associated factors included age at diagnosis between 10-18 years (OR 1.94 [95% CI 1.19-3.16]), underweight (OR 3.09 [1.42-6.69]), cranial irradiation (OR 2.65 [1.59-4.34]), total body irradiation (OR 3.28 [1.48-7.28]), cisplatin dose of at least 600 mg/m2 (OR 3.93 [1.45-10.67]), higher carboplatin doses (per g/m2; OR 1.15 [1.02-1.31]), cyclophosphamide equivalent dose of at least 20 g/m2 (OR 3.90 [1.65-9.24]), hyperthyroidism (OR 2.87 [1.06-7.76]), bone mineral density Z score <=-2 (OR 2.85 [1.54-5.29]), and folic acid deficiency (OR 2.04 [1.20-3.46]). Male sex (OR 4.56 [95%CI 2.26-9.17]), lower BMI (continuous, OR 0.52 [0.45-0.60]), cranial irradiation (OR 3.87 [1.80-8.31]), total body irradiation (OR 4.52 [1.67-12.20]), hypogonadism (OR 3.96 [1.40-11.18]), growth hormone deficiency (OR 4.66 [1.44-15.15]), and vitamin B12 deficiency (OR 6.26 [2.17-1.81]) were significantly associated with sarcopenia. Interpretation: Our findings show that frailty and sarcopenia occur already at a mean age of 33 years in childhood cancer survivors. Early recognition and interventions for endocrine disorders and dietary deficiencies could be important in minimising the risk of pre-frailty, frailty, and sarcopenia in this population.

Show moreSimple Summary Children treated for hemato-oncological diseases are at risk of muscle deterioration, such as loss of muscle mass and muscle weakness, with consequent impaired physical functioning. An easy screening tool will facilitate the early identification of children at risk and will support clinical decision making. We investigated the accuracy of an easy screening tool: the pediatric SARC-F (PED-SARC-F), for identifying functional sarcopenia in pediatric hemato-oncology patients. Functional sarcopenia indicates low muscle strength combined with low physical performance. We showed that the PED-SARC-F has a 90% accuracy in identifying pediatric hemato-oncology patients with functional sarcopenia. A PED-SARC-F cut-off point of >= 5 had the highest specificity (91%) and limits unnecessary assessments in patients who are not at risk of sarcopenia. This tool can be used to identify children that need a physiotherapy assessment and further interventions to prevent physical deterioration during and shortly after treatment for a hemato-oncology disease. Sarcopenia in pediatric hemato-oncology patients is undesirable because of the consequences it may have for treatment continuation and outcome, physical abilities and participation in daily life. An easy-to-use screening tool for sarcopenia will facilitate the identification of children at risk who need interventions to prevent serious physical deterioration. In the elderly, the use of the SARC-F score as a case-finding tool for sarcopenia is recommended. The aim of this cross-sectional study was to investigate the accuracy of the pediatric SARC-F (PED-SARC-F) for identifying sarcopenia in pediatric hemato-oncology patients, including the determination of a cut-off point for clinical use. Patients 3-20 years of age, under active treatment or within 12 months after treatment cessation were eligible. Patients had a physiotherapy assessment including a PED-SARC-F (0-10) and measurements of muscle strength (handheld dynamometry), physical performance (various tests) and/or muscle mass (bio-impedance analysis), as part of the standard of care. Spearman's correlation coefficient (r(s)) between the PED-SARC-F and physiotherapy outcomes were calculated. Structural sarcopenia was defined as low appendicular skeletal muscle mass (ASMM) in combination with low muscle strength and/or low physical performance. Functional sarcopenia indicated low muscle strength combined with low physical performance. Multiple logistic regression models were estimated to study the associations between the PED-SARC-F and structural/functional sarcopenia. To evaluate which cut-off point provides the most accurate classification, the area under the receiver operating characteristic curve (AUCs), sensitivity and specificity per point were calculated. In total, 215 assessments were included, 62% were performed in boys and the median age was 12.9 years (interquartile range: 8.5-15.8). The PED-SARC-F scores correlated moderately with the measurements of muscle strength (r(s) = -0.37 to -0.47, p < 0.001) and physical performance (r(s) = -0.45 to -0.66, p < 0.001), and weakly with ASMM (r(s) = -0.27, p < 0.001). The PED-SARC-F had an AUC of 0.90 (95% confidence interval (CI) = 0.84-0.95) for functional sarcopenia and 0.79 (95% CI = 0.68-0.90) for structural sarcopenia. A cut-off point of >= 5 had the highest specificity of 96% and a sensitivity of 74%.In conclusion, we adapted the SARC-F to a pediatric version, confirmed its excellent diagnostic accuracy for identifying functional sarcopenia and defined a clinically useful cut-off point in pediatric hemato-oncology patients.

Show moreSimple Summary: Hearing loss (HL) can be a side effect of paediatric cancer treatment and can be caused by chemotherapy but also local therapies such as radiotherapy and/or surgery of the head and neck region. In this study, the frequency and patterns of HL were assessed in survivors of head and neck rhabdomyosarcoma (HNRMS). Our secondary aim was to look into the dose-effect relationship between radiotherapy dose on the cochlea and the presence of HL. Forty-nine survivors of HNRMS were included in this study, forty-two of them underwent audiological evaluation. HL was found in up to 19% of the survivors. Four survivors had low frequencies HL with normal hearing or milder HL in the higher frequencies. In our series, HL (>= Muenster 2b) was significantly associated with the maximum cochlear irradiation dose (p = 0.047). More research is needed on HL patterns in HNRMS survivors and on the radiotherapy dose-effect relationship. Purpose: The frequency and patterns of HL in a HNRMS survivor cohort were investigated. A dose-effect relationship between the dose to the cochlea and HL was explored. Methods: Dutch survivors treated for HNRMS between 1993 and 2017 with no relapse and at least two years after the end of treatment were eligible for inclusion. The survivors were evaluated for HL with pure-tone audiometry. HL was graded according to the Muenster, Common Terminology Criteria for Adverse Events (CTCAE) v4.03 and International Society for Paediatric Oncology (SIOP) classification. We defined deleterious HL as Muenster >= 2b, CTCAE >= 2, and SIOP >= 2. Mixed-effects logistic regression was used to search for the dose-effect relationship between the irradiation dose to the cochlea and the occurrence of HL. Results: Forty-two HNRMS survivors underwent pure-tone audiometry. The Muenster, CTCAE and SIOP classification showed that 19.0% (n = 8), 14.2% (n = 6) and 11.9% (n = 5) of survivors suffered from HL, respectively. A low-frequency HL pattern with normal hearing or milder hearing loss in the higher frequencies was seen in four survivors. The maximum cochlear irradiation dose was significantly associated with HL (>= Muenster 2b) (p = 0.047). In our series, HL (>= Muenster 2b) was especially observed when the maximum dose to the cochlea exceeded 19 Gy. Conclusion: HL occurred in up to 19% of survivors of HNRMS. More research is needed on HL patterns in HNRMS survivors and on radiotherapy dose-effect relationships. Show less

Show moreBackground: Anthracyclines and radiotherapy involving the heart region are cardiotoxic, but the potential car-diotoxicity of vincristine remains unknown. We assessed cardiac function in vincristine-treated >5-year child-hood cancer survivors (CCS). Methods and results: We cross-sectionally compared echocardiograms of 101 vincristine-treated CCS (median age 35 years [range: 17-53], median vincristine dose 63 mg/m2) from the national Dutch Childhood Cancer Survivor Study, LATER cohort, to 101 age-and sex-matched controls. CCS treated with anthracyclines, radiotherapy involving the heart region, cyclophosphamide or ifosfamide were excluded. Twelve CCS (14%) versus four controls (4%; p 0.034) had a decreased left ventricular ejection fraction (LVEF; men <52%, women <54%). Mean LVEF was 58.4% versus 59.7% (p 0.050). Global longitudinal strain (GLS) was abnormal in nineteen (24%) CCS versus eight controls (9%; p 0.011). Mean GLS was 19.0% versus 20.1% (p 0.001). No >= grade 2 diastolic dysfunction was detected. In multivariable logistic regression analysis CCS had higher risk of abnormal GLS (OR 3.55, p 0.012), but not abnormal LVEF (OR 3.07, p 0.065), than controls. Blood pressure and smoking history contributed to variation in LVEF, whereas obesity and diastolic blood pressure contributed to variation in GLS. Cumulative vincristine dose was not associated with either abnormal LVEF or abnormal GLS in multivariable models corrected for age and sex (OR per 50 mg/m2: 0.88, p 0.85 and 1.14, p 0.82, respectively). Conclusions: Vincristine-treated long-term CCS showed an abnormal GLS more frequently than controls. Their risk for future clinical cardiac events and the role of risk factor modification should be further elucidated. Show less

Show moreChildhood cancer survivors (CCS) are at risk of kidney dysfunction. Recently, the shrunken pore syndrome (SPS) has been described, which is characterized by selectively impaired filtration of larger molecules like cystatin C, while filtration of smaller molecules like creatinine is unaltered. It has been associated with increased mortality, even in the presence of a normal estimated glomerular filtration rate (eGFR). The aim of this study was to evaluate the prevalence of SPS in CCS exposed to potentially nephrotoxic therapy. In the Dutch Childhood Cancer Survivor Study (DCCSS)-LATER 2 Renal study, a nationwide cross-sectional cohort study, 1024 CCS >= 5 years after diagnosis, aged >= 18 years at study, treated between 1963-2001 with nephrectomy, abdominal radiotherapy, total body irradiation, cisplatin, carboplatin, ifosfamide, high-dose cyclophosphamide or hematopoietic stem cell transplantation participated, and 500 age- and sex-matched controls form Lifelines. SPS was defined as an eGFR(cys)/eGFR(cr) ratio <0.6 in the absence of non-GFR determinants of cystatin C and creatinine metabolism (i.e. hyperthyroidism, corticosteroids, underweight). Three pairs of eGFR-equations were used; CKD-EPIcys/CKD-EPIcr, CAPA/LMR, and FAS(cys)/FAS(age). Median age was 32 years. Although an eGFR(cys)/eGFR(cr) ratio <0.6 was more common in CCS (1.0%) than controls (0%) based on the CKD-EPI equations, most cases were explained by non-GFR determinants. The prevalence of SPS in CCS was 0.3% (CKD-EPI equations), 0.2% (CAPA/LMR) and 0.1% (FAS equations), and not increased compared to controls. CCS treated with nephrotoxic therapy are not at increased risk for SPS compared to controls. Yet, non-GFR determinants are more common and should be taken into account when estimating GFR. Show less

Show moreBackgroundPediatric differentiated thyroid cancer (DTC) has an excellent prognosis but unknown late effects of treatment. The initial cardiac evaluation showed subclinical diastolic dysfunction in 20% of adult survivors. The objective of this follow-up study was to determine the clinical course of this finding. MethodsThis multicenter study, conducted between 2018 and 2020, re-evaluated survivors after 5 years. The primary endpoint was echocardiographic diastolic cardiac function (depicted by the mean of the early diastolic septal and early diastolic lateral tissue velocity (e' mean)). Secondary endpoints were other echocardiographic parameters and plasma biomarkers. ResultsFollow-up evaluation was completed in 47 (71.2%) of 66 survivors who had completed their initial evaluation. Of these 47 survivors, 87.2% were women. The median age was 39.8 years (range: 18.8-60.3), and the median follow-up after the initial diagnosis was 23.4 years (range: 10.2-48.8). Between the first and second evaluation, the e' mean significantly decreased by 2.1 cm/s (s.d. 2.3 cm/s, P < 0.001). The median left ventricular ejection fraction did not significantly change (58.0% vs 59.0%, P= NS). In the best explanatory model of e' mean, multivariate linear regression analysis showed that BMI and age were significantly associated with e' mean (beta coefficient: -0.169, 95% CI: -0.292; -0.047, P = 0.008 and beta coefficient: -0.177, 95% CI: -0.240; -0.113, P < 0.001, respectively). Conclusions and relevanceIn these relatively young survivors of pediatric DTC, diastolic function decreased significantly during 5-year follow-up and is possibly more pronounced than in normal aging. This finding requires further follow-up to assess clinical consequences. Show less

Show moreChildhood cancer survivors (CCS) are at increased risk to develop metabolic syndrome (MetS), diabetes, and cardiovascular disease. Common criteria underestimate adiposity and possibly underdiagnose MetS, particularly after abdominal radiotherapy. A systematic literature review and meta-analysis on the diagnostic and predictive value of nine newer MetS related biomarkers (adiponectin, leptin, uric acid, hsCRP, TNF-alpha, IL-1, IL-6, apolipoprotein B (apoB), and lipoprotein(a) [lp(a)]) in survivors and adult non-cancer survivors was performed by searching PubMed and Embase. Evidence was summarized with GRADE after risk of bias evaluation (QUADAS-2/QUIPS). Eligible studies on promising biomarkers were pooled. We identified 175 general population and five CCS studies. In the general population, valuable predictive biomarkers are uric acid, adiponectin, hsCRP and apoB (high level of evidence), and leptin (moderate level of evidence). Valuable diagnostic biomarkers are hsCRP, adiponectin, uric acid, and leptin (low, low, moderate, and high level of evidence, respectively). Meta-analysis showed OR for hyperuricemia of 2.94 (age-/sex-adjusted), OR per unit uric acid increase of 1.086 (unadjusted), and AUC for hsCRP of 0.71 (unadjusted). Uric acid, adiponectin, hsCRP, leptin, and apoB can be alternative biomarkers in the screening setting for MetS in survivors, to enhance early identification of those at high risk of subsequent complications.
