Psychological, educational, and social late effects in adolescent survivors of Wilms tumor: A report from the Childhood Cancer Survivor Study.

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.

Neurocognitive outcomes in long-term survivors of Wilms tumor: a report from the St. Jude Lifetime Cohort.

PURPOSE: To examine prevalence and predictors of neurocognitive outcomes, social attainment, emotional distress, and health-related quality of life (HRQOL) in long-term survivors of pediatric Wilms tumor (WT). METHODS: One hundred fifty-eight WT survivors (59% female; mean [SD] age 33 [9.1] years; time since diagnosis 29 [9.1] years) and 354 community controls (55.6% female; 35 [10.2] years) completed comprehensive neuropsychological testing and physical examination, including echocardiography/electrocardiography, pulmonary function tests, and endocrine evaluation. Self-report of emotional distress, HRQOL, and social attainment were collected. Impairment was defined in relation to both controls and normative data. Generalized linear models were developed to examine impact of treatment and chronic health conditions on outcomes. RESULTS: WT survivors performed poorer than norms and controls in 6 of 16 cognitive variables and 1 of 8 HRQOL variables, with scores ranging from - 0.64 (mathematics) to - 0.21 (verbal fluency) standard deviations below expectations. Compared to controls, WT survivors were less likely to graduate college (odds ratio 2.23, 95% confidence interval 1.46-3.41) and had more moderate to severe neurologic conditions (18.4% vs 8.2%, p < 0.001), which were associated with poor memory (ß = - 0.90, p < 0.001), attention (ß = - 1.02, p < 0.001), and HRQOL general health (ß = - 0.80, p = 0.0015). Treatment variables and cardiopulmonary morbidity (higher in survivors) were not associated with outcomes. CONCLUSIONS: Survivors of WT demonstrate impairment in neurocognitive function and have lower social attainment during adulthood, with poorer neurocognitive function associated with neurologic morbidity. IMPLICATIONS FOR CANCER SURVIVORS: Survivors of WT should be offered neurocognitive evaluations and rehabilitation. Neurologic conditions should be routinely assessed, and appropriate support offered to reduce risk for functional limitations.

Social adjustment in adolescent survivors of pediatric central nervous system tumors: A report from the Childhood Cancer Survivor Study.

BACKGROUND: The purpose of this study was to examine the prevalence and predictors of social difficulties in adolescent survivors of central nervous system (CNS) tumors. METHODS: Six hundred sixty-five survivors of CNS tumors (53.8% male and 51.7% treated with cranial radiation therapy [CRT]), who had a current median age of 15.0 years (range, 2.0-17.0 years) and were a median of 12.1 years (range, 8.0-17.7 years) from their diagnosis, were compared with 1376 survivors of solid tumors (50.4% male), who had a median age of 15.0 years (range, 12.0-17.0 years) and were a median of 13.2 years (range, 8.3-17.9 years) from their diagnosis, and 726 siblings (52.2% male), who had a median age of 15.0 years (range, 12.0-17.0 years). Social adjustment was measured with parent-proxy responses to the Behavior Problems Index. Latent profile analysis defined social classes. Multinomial logistic regression, adjusted for age, sex, and age at diagnosis, identified predictors of class membership. Path analyses tested mediating effects of physical limitations, sensory loss, and cognitive impairment on social outcomes. RESULTS: Caregivers reported that survivors of CNS tumors were more likely to have 0 friends (15.3%) and to interact with friends less than once per week (41.0%) in comparison with survivors of solid tumors (2.9% and 13.6%, respectively) and siblings (2.3% and 8.7%, respectively). Latent profile analysis identified 3 social classes for survivors of CNS tumors: well-adjusted (53.4%), social deficits (16.2%), and poor peer relationships (30.4%). However, 2 classes were identified for survivors of solid tumors and siblings: well-adjusted (86.2% and 91.1%, respectively) and social deficits (13.8% and 8.9%, respectively). CRT predicted class membership for CNS survivors (odds ratio [OR] for poor peer relationships, 1.16/10 Gy; 95% confidence interval [CI], 1.08-1.25; OR for social deficits 1.14/10 Gy; 95% CI, 1.04-1.25; reference, well-adjusted). Cognitive impairment mediated the association between all social outcomes and CRT (P values < .001). CONCLUSION: Almost 50% of survivors of CNS tumors experience social difficulties; the pattern is unique in comparison with solid tumor and sibling groups. Cognitive impairment is associated with increased risk, and this highlights the need for multitargeted interventions.

Comparative study of quality of life of adult survivors of childhood acute lymphocytic leukemia and Wilms’ tumor / Estudo comparativo da qualidade de vida de adultos sobreviventes de leucemia linfocítica aguda e tumor de Wilms na infância

Abstract Objective To analyze and compare the health-related quality of life of adult survivors of acute lymphocytic leukemia and Wilms’ tumor amongst themselves and in relation to healthy participants. Methods Ninety participants aged above 18 years were selected and divided into three groups, each comprising 30 individuals. The Control Group was composed of physically healthy subjects, with no cancer history; and there were two experimental groups: those diagnosed as acute lymphocytic leukemia, and those as Wilms’ Tumor. Quality of life was assessed over the telephone, using the Medical Outcomes Study 36-Item Short Form Health Survey. Results Male survivors presented with better results as compared to female survivors and controls in the Vitality domain, for acute lymphocytic leukemia (p=0.042) and Wilms’ tumor (p=0.013). For acute lymphocytic leukemia survivors, in Social aspects (p=0.031), Mental health (p=0.041), and Emotional aspects (p=0.040), the latter also for survivors of Wilms’ tumor (p=0.040). The best results related to the Functional capacity domain were recorded for the experimental group that had a late diagnosis of acute lymphocytic leukemia. There were significant differences between groups except for the Social and Emotional domains for self-perceived health, with positive responses that characterized their health as good, very good, and excellent. Conclusion Survivors of acute lymphocytic leukemia showed no evidence of relevant impairment of health-related quality of life. The Medical Outcomes Study 36-Item Short Form Health Survey (via telephone) can be a resource to access and evaluate survivors.

Overgrowth syndromes.

PURPOSE OF REVIEW: Human growth ensues from a complex interplay of physiological factors, in the wider setting of varying genetic traits and environmental influences. Intensive research in these divergent areas, and particularly in the field of genetics, continues to clarify the molecular basis of disorders which result in overgrowth, and it is therefore timely to provide a review of these findings. RECENT FINDINGS: This article provides an overview of the factors which regulate growth, followed by a discussion of the more commonly encountered overgrowth syndromes and their genetic basis as it is understood at the current time. There is also an added focus on recently discovered genetic associations in some conditions, such as Weaver, Perlman and Proteus syndromes. SUMMARY: New discoveries continue to be made regarding the genetic basis for many overgrowth syndromes and the development of a much needed molecular classification system for overgrowth may become possible as the interlinking functions of these genes on growth are unravelled. As there exists a wide spectrum of syndromes, disorders resulting in overgrowth can represent a diagnostic and therapeutic challenge, from those causing prenatal overgrowth with a poor prognosis to less severe genetic aberrations which are identified in later childhood or adult life.

Social outcomes in young adult survivors of low incidence childhood cancers.

INTRODUCTION: The intensity and duration of childhood cancer treatment may disrupt psychosocial development and thereby cause difficulties in transition into adulthood. The study objective was to assess social outcomes in early adulthood after successful treatment for childhood acute myeloid leukemia (AML), Wilms tumor (WT) and infratentorial astrocytoma (IA). METHODS: Nordic patients treated for AML, WT and IA from 1985 to 2001 identified from a database administered by NOPHO (Nordic Society of Paediatric Haematology and Oncology) were invited to participate in a postal survey. All cancer-free survivors treated at age >1 year who were >19 years at time of study were eligible. Seventy-four percent; 247/335 responded. An age-equivalent group (N = 1,814) from a Norwegian Census Study served as controls. RESULTS: Mean age of survivors was 23 years (range 19-34), 55% females. The proportion with academic education (>/=4 years) was similar in survivors and controls (28 vs. 32%). Fifty-nine percent of survivors were employed compared to 77% among controls (p < .01). More survivors were recipients of social benefits (6.7 vs. 3.1%, p < .01). There were no differences in marital status but parenthood was more common among controls (37 vs. 27%, p = .01). Controls lived longer in their parental homes (p = .01). Cancer type or treatment intensity had no statistically significant impact on results, except for parenthood. CONCLUSIONS AND IMPLICATIONS FOR CANCER SURVIVORS: The study revealed important differences in social outcomes between survivors and controls early in adult life. Specific difficulties pertain to studying social status in early adulthood because of the natural transition characteristics for this age group. Therefore, longer follow-up is warranted.

Does childhood cancer affect parental divorce rates? A population-based study.

PURPOSE Cancer in children may profoundly affect parents' personal relationships in terms of psychological stress and an increased care burden. This could hypothetically elevate divorce rates. Few studies on divorce occurrence exist, so the effect of childhood cancers on parental divorce rates was explored. PATIENTS AND METHODS Data on the entire Norwegian married population, age 17 to 69 years, with children age 0 to 20 years in 1974 to 2001 (N = 977,928 couples) were retrieved from the Cancer Registry, the Central Population Register, the Directorate of Taxes, and population censuses. Divorce rates for 4,590 couples who were parenting a child with cancer were compared with those of otherwise similar couples by discrete-time hazard regression models. Results Cancer in a child was not associated with an increased risk of parental divorce overall. An increased divorce rate was observed with Wilms tumor (odds ratio [OR], 1.52) but not with any of the other common childhood cancers. The child's age at diagnosis, time elapsed from diagnosis, and death from cancer did not influence divorce rates significantly. Increased divorce rates were observed for couples in whom the mothers had an education greater than high school level (OR, 1.16); the risk was particularly high shortly after diagnosis, for CNS cancers and Wilms tumors, for couples with children 0 to 9 years of age at diagnosis, and after a child's death. CONCLUSION This large, registry-based study shows that cancer in children is not associated with an increased parental divorce rate, except with Wilms tumors. Couples in whom the wife is highly educated appear to face increased divorce rates after a child's cancer, and this may warrant additional study.

Psychological status in childhood cancer survivors: a report from the Childhood Cancer Survivor Study.

Psychological quality of life (QOL), health-related QOL (HRQOL), and life satisfaction outcomes and their associated risk factors are reviewed for the large cohort of survivors and siblings in the Childhood Cancer Survivor Study (CCSS). This review includes previously published manuscripts that used CCSS data focused on psychological outcome measures, including the Brief Symptom Inventory (BSI-18), the Medical Outcomes Survey Short Form-36 (SF-36), the Cantril Ladder of Life, and other self-report questionnaires. Comparisons and contrasts are made between siblings and survivors, and to normative data when available, in light of demographic/health information and abstracted data from the medical record. These studies demonstrate that a significant proportion of survivors report more symptoms of global distress and poorer physical, but not emotional, domains of HRQOL. Other than brain tumor survivors, most survivors report both good present and expected future life satisfaction. Risk factors for psychological distress and poor HRQOL are female sex, lower educational attainment, unmarried status, annual household income less than $20,000, unemployment, lack of health insurance, presence of a major medical condition, and treatment with cranial radiation and/or surgery. Cranial irradiation impacted neurocognitive outcomes, especially in brain tumor survivors. Psychological distress also predicted poor health behaviors, including smoking, alcohol use, fatigue, and altered sleep. Psychological distress and pain predicted use of complementary and alternative medicine. Overall, most survivors are psychologically healthy and report satisfaction with their lives. However, certain groups of childhood cancer survivors are at high risk for psychological distress, neurocognitive dysfunction, and poor HRQOL, especially in physical domains. These findings suggest targeting interventions for groups at highest risk for adverse outcomes and examining the positive growth that remains despite the trauma of childhood cancer.

Scholastic achievement of children with lymphoma or Wilms tumor at the end of comprehensive education--a nationwide, register-based study.

Cancer treatment may affect school performance. School report grades after childhood lymphomas and Wilms tumor have not been previously reported. All Finnish patients with Wilms tumor (N = 74), Hodgkin lymphoma (HL) (N = 99) and non-Hodgkin lymphoma (NHL) (N = 94) who were born in 1974-1986 and had achieved the age of 16 years were identified from the Finnish cancer registry. Population controls (N = 1329) were matched for age, gender and residence. Their 9th grade school reports were obtained from Statistics Finland. The overall average and grades for mother tongue, first foreign language, mathematics and physical education were compared between the patients and their controls. Almost all the patients (>98%) had finished their comprehensive school. NHL patients had lower overall averages than their controls (difference -0.27 grade units; 95% CI -0.39, -0.15). Irradiation or age at diagnosis did not explain this difference in NHL patients. The grades of NHL patients were significantly lower than those of their controls in each academic school subject, especially in mathematics (-0.45; 95% CI -0.63, -0.27). In mother tongue, girls with irradiation had greatest difference (-0.66, 95% CI -0.99, -0.34) to their controls. Patients with HL and Wilms tumor performed similarly or even better than their controls in all academic subjects. Grades for physical education were impaired in Wilms tumor patients (-0.20; 95% CI -0.33, -0.06). Impairment of school report grades was observed in patients with NHL. The difference to controls was greatest in mathematics. The patients with HL and Wilms tumor, who had not received any central nervous system directed therapy, achieved equally good grades as their controls in all the academic subjects.

Tumor de Wilms: características clínicas e cirúrgicas / Wilms'tumor: clinical and surgical features

O tumor de Wilms (TW) é o tumor renal maligno mais comum na infância. O conhecimento de certas características clínicas e a realização de procedimentos cirúrgicos adequados podem ter impacto no prognóstico desta doença. Revisados prontuários de pacientes com diagnóstico de TW entre 1989 e 2005. Coletados dados demogrãficos, caracteríisticas clínicas e avaliação de procedimentos cirúrgicos. Durante o ato operatório, 38 pacientes foram submetidos à avaliação do rim contralateral através da palpação e em 13 relatos de cirurgia não foram encontradas descrições. Ruptura tumoral em 1 paciente; em dez prontuários havia registro de ausência de ruptura tumoral e em 41 prontuários não havia qualquer menção quanto à presença ou ausência dessa complicação. A histopatologia confirmou 45 casos de histologia favorável e os demais de histologia desfavorável. Os resultados apresentados permitem concluir que os pacientes estudados apresentam características demográficas gerais semelhantes aos da literatura.Considerando-se que em um número expressivo de pacientes observou-se falta de aderência a certas etapas do procedimento cirúrgico, incluindo ausência de biópsia de linfonodos e atrasos na realização da ressecção tumoral, os autores recomendam que o cirurgião pediátrico tenha uma participação mais efetiva na equipe multidisciplinar e na elaboração das rotinas do protocolo cirúrgico para pacientes com TW

Wilms´tumor (WT) is the most common malignant renal tumor in childhood. The knowledge of the clinical characteristics and the accomplishment of standard surgical procedures may have an impact in the prognosis of this disease. Medical records of newly diagnosed WT patients treated from 1989 to 2005 were reviewed. We collected data on demographics, clinical characteristics and whether certain recommended surgical standard procedures were carried out.The surgeon in 38 patients performed palpation of the contralateral kidney and in 13 medical records there was no report whether this procedure was carried out. Tumor spillage was reported 1 patient, reported as absent in 10 patients; we were unable to find any mention about tumor rupture on the surgeon’s report for 41 patients. There were 45 cases of favorable histology and 7 of unfavorable histology. The OS was of 69%, 71%, 79%, 50% and 40% for the stages I, II, III, IV and V, respectively. Five years OS was 73% and 65,2% for patients submitted to surgery before and after the 6th week after diagnosis, respectively. The results of the present study indicate that patients in this study show demographic characters similar to the literature. Considering that surgeons did not performed standard recommended surgical procedure such as lymph nodes biopsy and carried out late surgical resection of the primary tumor in many patients, there is a need for a more effective participation of the surgeon in the multidisciplinary team and possiblyin the designing protocols for the surgical management of patients with TW

Health-related quality of life in adult survivors of childhood Wilms tumor or neuroblastoma: A report from the childhood cancer survivor study.

BACKGROUND: Long-term survivors of Wilms tumor and neuroblastoma may experience significant late adverse effects from their disease and its therapy. Little is known, however, about the health-related quality of life experienced by these survivors. PROCEDURE: Health-related quality of life, measured by the 36-Item Short Form Health Survey (SF-36), was assessed from self-report in adult survivors of Wilms tumor (N = 654) and neuroblastoma (N = 432) who participated in the Childhood Cancer Survivor Study. RESULTS: More than 90% of the study population was 18-34 years old at interview, and 58% were females. There was no significant difference on any SF-36 subscale or summary scale between the two diagnostic groups. On average, survivors reported no decrement on the Physical Component Summary scale of the SF-36 when compared to population norms. However, both groups scored significantly below the population mean score (50) on the Mental Component Summary Scale of the SF-36 (Wilms tumor mean = 41.66, standard error = 2.19, P < 0.0001; neuroblastoma mean = 42.41, standard error = 2.23, P < 0.0001) reflecting decreased emotional health. Independent risk factors for lower scores on this scale included female gender, Native American race, unemployment, and household income below $20,000. CONCLUSIONS: Adult survivors of childhood Wilms tumor and neuroblastoma do not differ from population norms on most health-related quality of life (HRQL) measures. These data, however, indicate that the emotional well being of adult survivors may be compromised. Health care providers should be aware of the risk of adverse outcomes in emotional health even many years after treatment and cure.

Behavioral and educational limitations after chemotherapy for childhood acute lymphoblastic leukemia or Wilms tumor.

BACKGROUND: The improved prognosis of childhood cancer makes monitoring of functional outcome important. The purpose of this study was to evaluate behavioral and educational functioning in survivors of childhood acute lymphoblastic leukemia (ALL) or a Wilms tumor. In this study, children with ALL received central nervous system directed chemotherapy without cranial irradiation. METHODS: In a multicenter study, behavioral functioning and school performance was examined in 199 children age 4 to 18. Sixty-four children were at least 1 year from finishing treatment with chemotherapy for ALL (n = 28) or a Wilms tumor (n = 36). They were compared with siblings (n = 37) and with a control group of healthy schoolchildren (n = 98). RESULTS: A moderately increased risk of behavioral and educational problems was found in children with ALL but not in children with Wilms tumor. School performance was poorer in children with ALL attending primary school compared with same-age peers; however, the rate of utilization of special education services was low. Teacher-rated behavior and mathematics performance was correlated with attention function in children with ALL. An excess of problem behavior and underperformance at school was found in the ALL high-risk group compared with the standard-risk group. No differences were found between siblings and controls. CONCLUSION: Evidence is provided of subtle but significant behavioral and educational problems in survivors of childhood ALL, but no dysfunctions in survivors of a Wilms tumor. Careful follow-up of children with ALL treated with chemotherapy only is warranted.

Visuomotor control in survivors of childhood acute lymphoblastic leukemia treated with chemotherapy only.

Treatment for childhood acute lymphoblastic leukemia (ALL), which includes CNS prophylaxis, is associated with central and peripheral neurotoxicity. The purpose of the present study was to analyze the effects of chemotherapy on various levels of visuomotor control in survivors of childhood ALL treated without cranial irradiation, and to identify risk factors for possible deficits. Visuomotor function was compared between children after treatment for ALL (n = 34), children after treatment for Wilms tumor, which consists of non-CNS directed chemotherapy (n = 38), and healthy controls (n = 151). Three tasks were administered: a simple visual reaction time task and two tasks measuring visuomotor control with one requiring a higher level of cognitive control than the other. Visuomotor deficits were detected only in the ALL group, with poorer performance restricted to the condition requiring the highest level of control. Significant risk factors for poorer performance were female gender and a short time since end of treatment, and a trend was found for a young age at diagnosis. A high cumulative methotrexate dose was an adverse predictive factor in girls. The results indicate that chemotherapy-induced central neurotoxicity in childhood ALL treatment is associated with higher order visuomotor control deficits. Girls appear to be particularly vulnerable.

Neuropsychological outcome in long-term survivors of a childhood extracranial solid tumor who have undergone autologous bone marrow transplantation.

The purpose of this study was to evaluate neuropsychological and adaptive functioning of children who have undergone bone marrow transplantation (BMT) without previous cranial irradiation. In total, 76 children treated for an extracranial tumor with BMT without total body irradiation (TBI) were evaluated at least 5 years after the end of the treatment.Overall, their performance and skills were in the normal range and their professional and academic outcomes were satisfactory. Nevertheless, we observed a deleterious effect of deafness on verbal IQ associated with the previous administration of cisplatin during conventional chemotherapy. In addition, reading difficulties had arisen. This could be related to absence from kindergarten or primary school during hospitalization. Finally, in the younger subgroup, visual-perceptual skills were found to be more fragile.

Health status and health-related quality of life in survivors of cancer in childhood in Latin America: a MISPHO feasibility study.

Cancer is an increasing cause of disease-related death in childhood within developing countries, where the great majority of the world's children reside. The improving prospects for survival in such children, and the corresponding challenge of undertaking economic evaluations of related health interventions, provide a stimulus to study the health-status and health-related quality of life in survivors of cancer in childhood in Latin America. Spanish language versions of questionnaires for proxy assessors, based on the Health Utilities Index (HUI), were used to elicit responses from parents and physicians. The HUI is a family of multi-attribute, generic, preference-linked measures of health status and health-related quality of life that are reliable, responsive and valid, and have been used previously in pediatric oncology. Valid responses were received from 178 parents and 144 physicians in 6 centres in 4 countries (Cuba, Honduras, Colombia and Uruguay). For children with acute lymphoblastic leukemia the major morbidity burdens were in the attributes of emotion, cognition and pain. The overall burden of morbidity was greater in children with non-Hodgkin's lymphoma. In survivors of Hodgkin's disease and Wilms' tumor the attributes most affected were emotion and pain. In general, there was considerable agreement between the assessments provided independently by parents and physicians. This study demonstrates the feasibility of conducting such measurements in developing countries, and reveals similarities in health status and health-related quality of life to comparable populations in more privileged societies.
