RESUMEN
BACKGROUND: Pediatric brain tumor survivors (PBTS) experience neurocognitive late effects, including problems with working memory, processing speed, and other higher order skills. These skill domains are subserved by various white matter (WM) pathways, but not much is known about these brain-behavior links in PBTS. This study examined the anterior corona radiata (ACR), inferior fronto-occipital fasciculi (IFOF), and superior longitudinal fasciculi (SLF) by analyzing associations among diffusion metrics and neurocognition. PROCEDURE: Thirteen PBTS and 10 healthy controls (HC), aged 9-14 years, completed performance-based measures of processing speed and executive function, and parents rated their child's day-to-day executive skills. Children underwent magnetic resonance imaging (MRI) with diffusion weighted imaging that yielded fractional anisotropy (FA) and mean diffusivity (MD) values. Independent samples t-tests assessed group differences on neurocognitive and imaging measures, and pooled within-group correlations examined relationships among measures across groups. RESULTS: PBTS performed more poorly than HC on measures of processing speed, divided attention, and shifting (d = -1.08 to -1.44). WM microstructure differences were significant in MD values for the bilateral SLF and ACR, with PBTS showing higher diffusivity (d = 0.75 to 1.21). Better processing speed, divided attention, and shifting were associated with lower diffusivity in the IFOF, SLF, and ACR, but were not strongly correlated with FA. CONCLUSIONS: PBTS demonstrate poorer neurocognitive functioning that is linked to differences in WM microstructure, as evidenced by higher diffusivity in the ACR, SLF, and IFOF. These findings support the use of MD in understanding alterations in WM microstructure in PTBS and shed light on potential functions of these pathways.

OBJECTIVES: Adolescents with cancer often experience significant symptom burden and aggressive treatment near end-of-life. Increased adolescent involvement in care and decision-making may benefit health outcomes. Limited research has examined factors associated with adolescents' involvement in care in the context of advanced disease. Thus, we examined the impact of background factors and decision-making perceptions on both adolescents' involvement in care and their desired change in involvement. METHODS: Adolescents with advanced cancer (<60% survival or refractory/relapsed disease), ages 10-23 (n = 41; Mage = 15.37), were recruited approximately 1 month after diagnosis to complete measures of decision-making perceptions and their family role. Hierarchical regressions examined the contributions of background factors and decision-making perceptions to adolescents' frequency and desired involvement in their care. Qualitative interviews regarding decision-making were analyzed using deductive analysis. RESULTS: The model examining frequency of involvement in care was significant, F(5,34) = 3.12, p = .02, R2= .31. Older age was the only significant predictor (ß = .13, p= .003). The model examining desired involvement was non-significant, F(5,34) = 2.22, p = .075. Qualitative analysis indicated that (1) older adolescents have more involvement in decision-making, (2) collaborative decision-making occurred between the adolescent and extended family, and (3) adolescents trusted others to make decisions. Integration of qualitative and quantitative data revealed congruence in findings. SIGNIFICANCE OF RESULTS: Adolescents with advanced cancer, who consider how decisions directly impact them and prefer greater autonomy, may be more involved in their medical care. Research is needed to identify other longitudinal predictors of decision-making and involvement in care. Providers should consider encouraging families to communicate their preferences and engage in shared decision-making.
RESUMEN
PURPOSE: Pediatric cancer survivors may have lower quality of life (QoL), but most research has assessed outcomes either in treatment or long-term survivorship. We focused on early survivorship (i.e., 3 and 5 years post-diagnosis), examining the impact of CNS-directed treatment on child QoL, as well as sex and age at diagnosis as potential moderators. METHODS: Families of children with cancer (ages 5-17) were recruited at diagnosis or relapse (N = 336). Survivors completed the PedsQL at 3 (n = 96) and 5 years (n = 108), along with mothers (101 and 105, respectively) and fathers (45 and 53, respectively). The impact of CNS treatment, sex, and age at diagnosis on child QoL was examined over both time since diagnosis and time since last treatment using mixed model analyses. RESULTS: Parent-report of the child's total QoL was in the normative range and stable between 3 and 5 years when examining time since diagnosis, while child reported QoL improved over time (p = 0.04). In terms of time since last treatment, mother and child both reported the child's QoL improved over time (p = 0.0002 and p = 0.0006, respectively). Based on parent-report, males with CNS-directed treatment had lower total QoL than females and males who did not receive CNS-directed treatment. Age at diagnosis did not moderate the impact of treatment type on total QoL. CONCLUSIONS: Quality of life (QoL) in early survivorship may be low among males who received CNS-directed treatment. However, this was only evident on parent-report. Interventions to improve child QoL should focus on male survivors who received CNS-directed treatment, as well as females regardless of treatment type.

OBJECTIVES: This qualitative study examined how families share information and feelings about advanced pediatric cancer from the perspective of both parents and children, as well as how these perspectives vary by child developmental stage. METHODS: Participants (24 mothers, 20 fathers, 23 youth [children and adolescents]) were from a larger longitudinal study at an academic pediatric hospital. Eligible youth had advanced cancer (physician-estimated prognosis of <60%, relapse, or refractory disease), were aged 5-19 years (>8 years old to participate independently), had an English-speaking parent, and lived within 140 miles of the hospital. Interviews were completed at enrollment and asked how families share information and emotions about the child's cancer as a family. RESULTS: Saturation was reached at 20 interviews for mothers, fathers, and youth. Analyses revealed 4 major themes: (A) parents managing cancer-related information based on child age/developmental stage and processing styles of family members; (B) parents withholding poor prognosis information and emotions to maintain positivity; (C) lack of personal and familial emotion sharing; and (D) emotion sharing among their family and externally. Both parents and youth endorsed themes A, C, and D, but only parents endorsed theme B. Adolescents endorsed more themes than children. Parents of children (as opposed to adolescents) endorsed theme A more. SIGNIFICANCE OF RESULTS: Although both parents and youth with advanced cancer were generally willing to talk about treatment, emotions were not consistently shared. Perspectives varied depending on the child's developmental stage. Clinicians should assess parent and child information and emotion-sharing needs and provide individualized support to families regarding communication about advanced cancer.
RESUMEN
OBJECTIVE: Meaning-making may assist individuals in adaptation to stressful life events, particularly bereavement. However, few studies have examined meaning-making among pediatric populations with advanced illness to understand how this process unfolds before the child's death. This study explores meaning-making pre-bereavement among children with advanced cancer and their parents. METHODS: As part of a larger study examining shared decision-making near the end of life, 24 children with advanced cancer and/or high-risk cancer, 26 mothers, and 11 fathers participated in individual, semi-structured interviews. Analyses focused on questions regarding meaning-making. Four coders analyzed the data via directed content analysis. RESULTS: Three major meaning-making themes emerged: (1) sense-making (i.e., unknown, no sense/meaning, religious/spiritual explanations, scientific explanations), (2) benefit-finding, and (3) purpose/legacy. Some stated they were unable to make sense of the diagnosis, because there was no reason, they were not there yet, or they were dealing with the situation and moving forward. Others reported finding meaning through spiritual and scientific explanations. Many identified benefits related to the child's illness, such as personal growth and stronger relationships. Some parents expressed their purpose in life was to live for their children, while others shared their child's legacy as a way to find meaning. CONCLUSIONS: Our findings highlight the struggle children and parents often face when attempting to make sense of the child's advanced or high-risk illness. Clinicians might consider if meaning-centered interventions designed for use in adults at the end of life and bereaved parents may be helpful for children with advanced or high-risk cancer and their parents.

BACKGROUND: Central nervous system (CNS)-directed treatments can cause long-term academic, social, and emotional difficulties for children with cancer. However, limited research has examined the emergence of problems longitudinally and has often stratified risk by diagnosis alone. Therefore, this study compared competence and adjustment in children, who did and did not receive CNS-directed treatment, over the first 3 years following a cancer diagnosis. PROCEDURE: Mothers, fathers, and children (ages 5-18 years at diagnosis) from 217 families reported on the child's competence (academic, social) and adjustment (anxious/depressed, withdrawn/depressed) near a new cancer diagnosis or relapse and 3 years later. Children were categorized into CNS-directed treatment (n = 112; including cranial radiation, intrathecal chemotherapy, and/or neurosurgery) and non-CNS-directed treatment (n = 105) groups. RESULTS: At enrollment, there were few differences in competence and emotional adjustment among children based on treatment or diagnostic group. At 3 years, mothers and fathers reported poorer social competence for the CNS-directed treatment group, and fathers reported poorer school competence for the CNS-directed treatment group. Over time, father ratings of social competence increased for the non-CNS-directed treatment group, but not the CNS-directed treatment group. While father ratings of academic competence declined for the CNS-directed treatment group, mother ratings declined the most for children diagnosed with a brain tumor. All children demonstrated higher anxious/depressed scores over time. CONCLUSIONS: CNS-directed treatment may be a valuable indicator to identify childhood cancer survivors at risk for poor competence during early survivorship. Follow-up screening and supportive services are recommended, as well as additional longitudinal research.

BACKGROUND: Pediatric hematology, oncology, and hematopoietic cell transplantation (HCT) patients are at increased risk for bloodstream infections. The authors sought to evaluate the influence of a standardized best practice central venous catheter (CVC) maintenance bundle on the burden of and risk factors for mucosal barrier injury (MBI) and non-MBI central line-associated bloodstream infections (CLABSIs) across a common inpatient and ambulatory continuum in this high-risk population. METHODS: A retrospective cohort study of patients with underlying malignancy, hematologic disorders, and HCT recipients with a CVC in place at the time of CLABSI diagnosis in both inpatient and ambulatory settings from January 1, 2012 to December 31, 2016. Descriptive, nonparametric statistics were used to describe patient characteristics and outcomes. Logistic regression analyses were applied to identify potential risk factors for inpatient versus ambulatory and MBI versus non-MBI CLABSI. RESULTS: During the 5-year period, 118 of 808 (14.6%) patients had 159 laboratory-confirmed CLABSIs for ambulatory and inpatient CLABSI rates of 0.27 CLABSI/1000 and 2.2 CLABSI/1000 CVC days, respectively. CLABSI occurred more frequently in hospitalized patients after HCT and with underlying leukemia, most frequently caused by Gram-negative bacteria. MBI CLABSI accounted for 42% of all CLABSI with a 3-fold higher risk in hospitalized patients. Having multiple CVC or a CVC that was not a port independently associated with higher CLABSI risk. CONCLUSIONS: In our cohort, non-MBI CLABSI continued to account for the majority of CLABSI. CVC type is independently associated with higher overall CLABSI risk. Further studies are needed to reliably define additional prevention strategies when CLABSI maintenance bundles elements are optimized in this high-risk population.

PURPOSE: Young individuals face a variety of developmental tasks as they mature into adulthood. For survivors of childhood cancer, growing up may be more difficult due to their illness and late effects from treatment. This study is the first to quantitatively examine perceptions of maturity and how these perceptions contribute to satisfaction with life among young adult survivors of childhood cancer. METHODS: Ninety survivors of childhood cancer (Mage = 29.8; 7-37 years post-diagnosis) were recruited to complete online surveys on how mature they felt relative to peers, their perceived maturity on three domains (financial, personal, social), and life satisfaction. RESULTS: Most survivors (62%; n = 56) felt they grew up faster than their peers, and over half (56%; n = 50) felt more mature. Perceived maturity was high on all three domains, but brain tumor survivors reported significantly lower maturity than other survivors (d = 0.76-1.11). All maturity domains were positively associated with life satisfaction (r = .49-.56). Hierarchical linear regressions indicated that 44% of the variance in life satisfaction was explained by perceptions of growing up slower (ß = - 1.08, p = .004) and marginally by greater perceived personal maturity (ß = 0.45, p = .061). CONCLUSIONS: Childhood cancer can influence development, with most survivors feeling that they grew up faster and were more mature than peers. Personal maturity was related to life satisfaction, with survivors of brain tumors or those who felt they grew up slower at greatest risk for lower life satisfaction. Future research and clinical practice should consider survivors' development and maturation across the life span to promote overall well-being.

OBJECTIVE: The majority of childhood cancer survivors develop at least one late effect subsequent to treatment (eg, cardiovascular disease and obesity). Consistent engagement in recommended health behaviors may mitigate some of these conditions. Researchers have identified early survivorship as a teachable moment, yet few studies have examined positive health behaviors during this period. METHODS: Families of children with cancer (ages 5-17) were initially recruited following a diagnosis or relapse of cancer. Three years post diagnosis, survivors (n = 82, Mage = 13.3, SD = 3.7) and their mothers (n = 103, Mage = 41.1, SD = 7.6) completed a questionnaire assessing exercise, dietary, and sleep patterns among survivors. A follow-up assessment was conducted 2 years later. Mixed models tested change in health behavior over time. RESULTS: At 3- and 5-year post diagnosis, mother and self-report indicated that few survivors engaged in appropriate levels of low-intensity exercise, fruit/vegetable intake, and dairy consumption. However, most survivors engaged in recommended levels of high intensity exercise, fast food restriction, and sleep. Health behaviors remained stable over time, except for mother report of sleep duration, which decreased (b = -0.6, P < 0.001). Brain tumor diagnosis predicted a larger decrease in self-report of sleep duration compared with other diagnoses (P = 0.04). Income predicted fast food intake such that higher income was associated with decreased intake over time, whereas lower income was associated with increased intake (P = 0.04). CONCLUSIONS: During early survivorship, several health behaviors fell short of expectations for exercise and diet and did not improve upon reaching 5-year post diagnosis. Providers should evaluate survivors' health behaviors, including sleep, early and often, intervening when necessary.

OBJECTIVE: The Cancer Care Index (CCI), a single metric that sums the number of undesirable patient events in a given time frame (either preventable harm events or missed opportunities to provide optimal care), resulted in a 42% improvement in performance. Our objective was to test the index concept in other service lines to determine whether similar performance improvement occurred. STUDY DESIGN: Care indices were developed and introduced in 3 additional service lines: Nephrology (Chronic Kidney Disease Care Index; CKDCI), Pulmonology (Lung Transplantation Care Index; LTCI), and Otolaryngology (Tracheostomy Care Index; TCI). After reaching agreement on specific harms to be avoided and elements of optimal care that should be reliably delivered, these items were compiled into indices that were updated monthly. Reports included each element individually and the total for all elements. Baseline performance was calculated retrospectively for the previous year. RESULTS: Significant improvement in performance occurred in each program following implementation of the clinical indices. The CKDCI was decreased by 63.2% (P < .001), the LTCI was decreased by 89.5% (P < .001), and the TCI was decreased by 53.0% (P < .001). Surveyed staff indicated satisfaction with use of the metric. CONCLUSIONS: Clinical indices are useful for evaluating and managing the overall reliability of a program's ability to deliver optimal care, and are associated with improved clinical performance and satisfaction by service line staff when incorporated into a program's operation.

OBJECTIVE: To extend the limited research on psychosexual development among childhood cancer survivors, by not only focusing on the prevalence and age of milestone attainment, but also survivors' attitudes toward the timing of reaching such milestones. METHODS: Adult survivors of childhood cancer (N = 90; Mage = 29.8, SD = 5.2), recruited from a US pediatric institution, completed online surveys indicating whether they had reached 5 milestones of psychosexual development (ie, first kiss, first boy-/girlfriend, first physical intimacy, sexual debut, first time in love), age at attainment, and perceptions about the timing (ie, right time, wished it had happened earlier, wished they had waited). RESULTS: Almost all survivors had reached each milestone (≥90%), except for sexual debut (83.3%). Survivors reported their first kiss as the earliest milestone at age 14.6 (N = 82, 92%) and falling in love as the latest milestone at age 18.8 (N = 80; 90%). This timing did not differ by sex/cancer-specific factors. Most survivors (~60%) felt they reached each milestone at the right time. Compared with US normative data, both male and female survivors were less likely to have experienced their sexual debut and were approximately 1.5 years older at sexual debut. Nevertheless, 59% of survivors felt that this timing was right and 31% wished they had waited longer. CONCLUSIONS: This is the first study to demonstrate that although childhood cancer survivors may delay some aspects of psychosexual development, most are satisfied with this timing. Research and clinical practice should emphasize survivors' perceptions/satisfaction toward psychosexual development rather than focusing only on normative milestone attainment.

BACKGROUND: In an effort to reduce morbidity and mortality from vaccine preventable influenza infection, national consensus guidelines recommend vaccination of patients who are immunocompromised as a result of receiving cancer therapy. Quality improvement (QI) processes are a proven method used to improve vaccination rates. PROCEDURE: We conducted a QI initiative aimed at increasing influenza vaccination in oncology patients undergoing active treatment. Primary drivers for the project focused on patient education, staff and provider education, and communication regarding vaccine-eligible patients. We performed a retrospective analysis of influenza infection among the vaccine-eligible population. This approach has validity at our institution because of the consistent follow-up and hospital admission pattern of cancer patients on active therapy such that nearly all follow-up care is delivered at our institution. RESULTS: We successfully achieved greater than 87% vaccination of eligible patients each vaccine season (September to March). During the recommended timeframe for delivering influenza vaccine between September and December of each vaccine season, we offered the vaccine to 100% of patients on active therapy and vaccinated >90%. Barriers to success, including vaccine refusals, increased late in the vaccine season. Influenza infection was documented in 0.5-7.3% of the vaccine-eligible group. CONCLUSION: A robust influenza vaccination program implemented using a standardized QI approach can sustain a high vaccination rate in a pediatric oncology population receiving active treatment. The influenza infection rate was under 10% in the vaccinated group.

BACKGROUND: Risk factors for impairment in psychosexual development and satisfaction among adult survivors of childhood cancer are poorly understood. The authors compared psychosexual outcomes between survivors and healthy controls, and tested whether at-risk survivors can be identified by 1) treatment neurotoxicity or 2) diagnosis. METHODS: A total of 144 young adult survivors of childhood cancer and 144 matched controls completed questionnaires regarding psychosexual development, sexual satisfaction, and satisfaction with relationship status. Survivors were aged 20 to 40 years and were 5 to 34 years after diagnosis. Using medical chart data, survivors were divided into non-neurotoxic (48 survivors), low-dose (36 survivors), and high-dose (58 survivors) neurotoxic treatment groups. RESULTS: Apart from having fewer lifetime sex partners, survivors did not appear to differ from controls. However, survivors of brain tumors and any survivor who received high-dose neurotoxic treatment reported the lowest rates of achieving milestones of psychosexual development, whereas sexual and relationship status satisfaction were found to be related to relationship status. Neurotoxic treatment intensity further distinguished between survivors of brain tumors with and without psychosexual impairment. CONCLUSIONS: The intensity of neurotoxic treatment may be a valuable indicator of risk for psychosexual impairment relative to diagnosis alone. Health care providers should assess romantic/sexual problems among survivors at risk and make referrals if needed. Cancer 2017;123:1869-1876. © 2017 American Cancer Society.

BACKGROUND: Families often express a need for additional information about neurocognitive late effects (NCLE) after a pediatric cancer diagnosis. Therefore, we examined: (i) differences in parent, child, and oncologist estimates of risk for NCLE; (ii) whether the estimates of parents and/or children change over time; and (iii) whether estimates are different for children treated with central nervous system (CNS) directed therapies. PROCEDURE: Mothers, fathers, and children (initial age: 5-17, self-report: >10) from 258 families reported their perceived likelihood of the child developing "thinking/learning problems" on a visual analog scale (0-100%) at 2 months (T1), 1 year (T2), and 3 years (T3) following cancer diagnosis/relapse. Oncologists estimated the likelihood of NCLE at T1. Children were separated into groups based on CNS-directed treatment (n = 137; neurosurgery, intrathecal chemotherapy, and/or craniospinal radiation) or no CNS treatment. RESULTS: Mother, father, and child estimates of risk for NCLE were similar to oncologists and to one another around diagnosis (T1). Although there were no significant mean differences, a considerable subset of family members either underestimated their child's risk for NCLE (>40%) or overestimated the risk for NCLE (20%) in comparison to oncologists. At T2 and T3, the estimates of mothers were significantly higher than children. Linear growth curves indicated that mothers' estimates for children with CNS-directed treatment significantly increased throughout the first 3 years of survivorship. CONCLUSIONS: Considering that accurate understanding of NCLE is essential to seeking appropriate assessment and intervention, healthcare providers should focus on implementing family-based education early in treatment and throughout survivorship care.

OBJECTIVE: Research on body image and sexual satisfaction after adult onset cancer has shown significant and lasting impairments regarding survivors' sexuality and romantic relationships. However, knowledge about these topics and their associations in adult survivors of childhood cancer is largely lacking. METHODS: Participants completed web-based questionnaires concerning body image, body dissociation, sexual satisfaction, and relationship status satisfaction (i.e., satisfaction with either being in a relationship or being single). Survivors (n = 87) and controls (n = 87) were matched on age and gender, with a mean age of 27 years (range: 20-40). Survivors were most often diagnosed with leukemia (46%), at an average of 16 years prior to study participation (range: 6-33 years). RESULTS: Similar numbers of survivors and controls were single (n = 24/31), in a committed relationship (n = 33/23), or married (n = 30/33). Survivors and controls reported comparable levels of body image, body dissociation, sexual experiences, and sexual and status satisfaction (d = 0.15-0.28). Higher status satisfaction was associated with being in a relationship (compared with being single, ß = 0.439), more positive body image (ß = 0.196), and higher sexual satisfaction (ß = 0.200). CONCLUSIONS: Adult survivors of childhood cancer were comparable to healthy peers regarding views of their bodies and psychosexual development, which was unexpected. Independent of whether people experienced cancer or not, their status satisfaction was associated with their relationship status, body image, and sexual satisfaction. Future research should explore why sexual and body problems are identified after adult onset cancer, whereas this seems to be less of a problem in childhood cancer survivors.

PURPOSE: Children receiving radiotherapy of the head, neck, or chest as treatment of primary malignancies are at increased risk for secondary thyroid malignancy. We hypothesized that current standards (yearly thyroid physical examination) lead to a substantial number of missed thyroid nodules. Our objectives were: (1) use thyroid ultrasound to assess thyroid nodules in childhood cancer survivors; and (2) compare prevalence of thyroid nodules in thyroid radiation-exposed patients as compared with cancer survivors without radiation exposure. METHODS: We recruited 60 patients with thyroid radiation and chemotherapy exposure (median age at cancer diagnosis 10.8 y) and 59 patients with chemotherapy exposure alone (median age at diagnosis 4.3 y) from our long-term survivorship clinics. Each patient had a thyroid physical examination and thyroid ultrasound performed. RESULTS: Thirty-three patients (27.7%) had nodules >0.3 cm of which 2 were palpated (6.1%). We found 22 radiated patients (36.7%) with nodules versus 11 nonradiated patients (18.6%) (P=0.03). Eleven patients were biopsied and 1 diagnosis of secondary papillary thyroid carcinoma was confirmed. CONCLUSION: Our study supports further examination of incorporating thyroid ultrasounds into long-term survivorship follow-up guidelines in radiation-exposed patients for the detection of thyroid nodules and secondary malignancies.

Children with high-grade glioma, including diffuse intrinsic pontine glioma (DIPG), have a poor prognosis despite multimodal therapy. Identifying novel therapeutic targets is critical to improve their outcome. We evaluated prognostic roles of telomere maintenance mechanisms in children with HGG, including DIPG. A multi-institutional retrospective study was conducted involving 50 flash-frozen HGG (35 non-brainstem; 15 DIPG) tumors from 45 children (30 non-brainstem; 15 DIPG). Telomerase activity, expression of hTERT mRNA (encoding telomerase catalytic component) and TERC (telomerase RNA template) and alternative lengthening of telomeres (ALT) mechanism were assayed. Cox Proportional Hazard regression analyses assessed association of clinical and pathological variables, TERC and hTERT levels, telomerase activity, and ALT use with progression-free or overall survival (OS). High TERC and hTERT expression was detected in 13/28 non-brainstem HGG samples as compared to non-neoplastic controls. High TERC and hTERT expression was identified in 13/15 and 11/15 DIPG samples, respectively, compared to controls. Evidence of ALT was noted in 3/11 DIPG and 10/19 non-brainstem HGG specimens. ALT and telomerase use were identified in 4/19 non-brainstem HGG and 2/11 DIPG specimens. In multivariable analyses, increased TERC and hTERT levels were associated with worse OS in patients with non-brainstem HGG, after controlling for tumor grade or resection extent. Children with HGG and DIPG, have increased hTERT and TERC expression. In children with non-brainstem HGG, increased TERC and hTERT expression levels are associated with a worse OS, making telomerase a promising potential therapeutic target in pediatric HGG.

BACKGROUND: Due to the devastating late effects associated with cranial irradiation in young children with central nervous system (CNS) tumors, treatment for these patients has evolved to include the use of intensive chemotherapy to either avoid or postpone irradiation. While survival outcomes have improved, late effects data in survivors treated on such regimens are needed. OBJECTIVE: This multi-institutional study comprehensively describes late effects in survivors treated on the Head Start I/II protocols. METHODS: Survivors of CNS tumors treated on Head Start I/II protocols were enrolled. Late effects data were collected using a validated parent-report questionnaire. Social, emotional, and behavioral functioning and quality of life were assessed using parent-report on the BASC-2 and CHQ-PF50 questionnaires. RESULTS: Twenty-one survivors (medulloblastoma = 13, sPNET = 4, ATRT = 1, ependymoma = 3) were enrolled. Ten (48%) were irradiation-free. Late effects (frequency; median time of onset since diagnosis) included ≥ grade III hearing loss (67%; 3.9 years), vision (67%; 4.1 years), hypothyroidism (33%; 4 years), growth hormone (GH) deficiency (48%; 4.7 years), dental (52%; 7.1 years), and no cases of secondary leukemia. Irradiation-free (vs. irradiated) survivors reported low rates of hypothyroidism (0/10 vs. 7/11; P = 0.004) and GH deficiency (2/10 vs. 8/11; P = 0.03). The BASC-2 and CHQPF-50 mean composite scores were within average ranges relative to healthy comparison norms. Neither age at diagnosis nor irradiation was associated with these scores. CONCLUSIONS: Irradiation-free Head Start survivors have lower risk of hypothyroidism and GH deficiency. Secondary leukemias are not reported. With extended follow-up, survivors demonstrate quality of life, social, emotional, and behavioral functioning within average ranges.

Retinoblastoma is an ocular cancer associated with genomic variation in the RB1 gene. In individuals with bilateral retinoblastoma, a germline variant in RB1 is identified in virtually all cases. We describe herein an individual with bilateral retinoblastoma for whom multiple clinical lab assays performed by outside commercial laboratories failed to identify a germline RB1 variant. Paired tumor/normal exome sequencing, long-read whole genome sequencing, and long-read isoform sequencing was performed on a translational research basis ultimately identified a germline likely de novo Long Interspersed Nuclear Element (LINE)-1 mediated deletion resulting in a premature stop of translation of RB1 as the underlying genetic cause of retinoblastoma in this individual. Based on these research findings, the LINE-1 mediated deletion was confirmed via Sanger sequencing in our clinical laboratory, and results were reported in the patient's medical record to allow for appropriate genetic counseling.
RESUMEN
This study investigates the outcome of children <10 years old with newly-diagnosed ependymoma treated on the prospective multinational "Head Start" III clinical trial. Between April 2004 and July 2009, 19 children with newly-diagnosed ependymoma were enrolled. All children were to receive five induction chemotherapy cycles followed by one consolidation cycle of myelo-ablative chemotherapy and autologous hematopoietic cell rescue. Children between 6 and 10 years of age or with residual tumor prior to consolidation were to receive irradiation thereafter. Median age of 19 children (8 female) was 20 months at diagnosis. Median follow up was 44 months. The primary site was infratentorial in 11 and supratentorial in 8 patients. Gross total resection was achieved in 10 patients. After induction chemotherapy, all three supratentorial ependymoma patients with residual disease achieved a complete response (CR), while only one of six infratentorial patients with residual disease achieved CR. Three infratentorial patients developed progressive disease during induction chemotherapy. All four infratentorial patients with residual disease who underwent autologous hematopoietic cell transplant, failed to achieve CR. Four patients received focal irradiation following chemotherapy. The 3-year event free survival (EFS) and overall survival (OS) for supratentorial ependymoma were 86 ± 13 % and 100 % respectively. The 3-year EFS and OS for infratentorial ependymoma were 27 ± 13 % and 73 ± 13 % respectively. The role of intensive induction and consolidation chemotherapy in deferring irradiation should be investigated further in children with supratentorial ependymoma with residual disease following surgery. This approach appears ineffective in children with infratentorial ependymoma in the absence of irradiation.
