Monitoring for Cardiovascular Disease in Survivors of Childhood Cancer: Report From the Cardiovascular Disease Task Force of the Children's Oncology Group

Curative therapy for childhood cancer has improved significantly in the last 2 decades such that, at present, ∼80% of all children with cancer are likely to survive ≥5 years after diagnosis. Prevention, early diagnosis, and treatment of long-term sequelae of therapy have become increasingly more significant as survival rates continue to improve. Cardiovascular disease is a well-recognized cause of increased late morbidity and mortality among survivors of childhood cancer. The Childrens Oncology Group Late Effects Committee and Nursing Discipline and Patient Advocacy Committee have recently developed guidelines for follow-up of long-term survivors of pediatric cancer. A multidisciplinary task force critically reviewed the existing literature to evaluate the evidence for the cardiovascular screening recommended by the Childrens Oncology Group guidelines. In this review we outline the clinical manifestations of late cardiovascular toxicities, suggest modalities and frequency of monitoring, and address some of the controversial and unresolved issues regarding cardiovascular disease in childhood cancer survivors.

Parent proxy–reported health‐related quality of life and fatigue in pediatric patients diagnosed with brain tumors and acute lymphoblastic leukemia

Pediatric patients with brain tumors (BT) are often excluded from health‐related quality of life (HRQOL) studies even though they experience more severe disease and treatment‐related sequelae than children with other types of cancer. Parent proxy assessments of HRQOL allow for greater inclusion of children who are developmentally immature, physically ill, or cognitively impaired.

Factors associated with health-related quality of life in pediatric cancer survivors†

Childhood cancer survivors are at risk for late effects of disease and treatment that may be attributed to multiple causes. This study describes health‐related quality of life (HRQOL) in childhood cancer survivors and identifies factors related to poor quality of life outcomes.

Prevalence and Predictors of Posttraumatic Stress Disorder in Adult Survivors of Childhood Cancer

OBJECTIVE: This study compared the prevalence of symptoms of posttraumatic stress disorder (PTSD), with functional impairment and/or clinical distress, among very long-term survivors of childhood cancer and a group of healthy siblings. METHODS: A total of 6542 childhood cancer survivors >18 years of age who received diagnoses between 1970 and 1986 and 368 siblings of cancer survivors completed a comprehensive demographic and health survey. RESULTS: A total of 589 survivors (9%) and 8 siblings (2%) reported functional impairment and/or clinical distress in addition to the set of symptoms consistent with a full diagnosis of PTSD. Survivors had more than fourfold greater risk of PTSD, compared with siblings (odds ratio [OR]: 4.14 [95% confidence interval [CI]: 2.08–8.25]). With controlling for demographic and treatment variables, increased risk of PTSD was associated with educational level of high school or less (OR: 1.51 [95% CI: 1.16–1.98]), being unmarried (OR: 1.99 [95% CI: 1.58–2.50]), having annual income below

20000 (OR: 1.63 [95% CI: 1.21–2.20]), and being unemployed (OR: 2.01 [95% CI: 1.62–2.51]). Intensive treatment also was associated with increased risk of full PTSD (OR: 1.36 [95% CI: 1.06–1.74]). CONCLUSIONS: PTSD was reported significantly more often by survivors of childhood cancer than by sibling control subjects. Although most survivors apparently are faring well, a subset reported significant impairment that may warrant targeted intervention.

Prevalence and Correlates of Fatigue in Long-Term Survivors of Childhood Leukemia

Brain tumors (BT) are second only to acute lymphoblastic leukemia as the most prevalent form of pediatric cancer, with BT 5‐year survival rates approaching 70%. With increased survival, quality of life has emerged as an essential health outcome. This investigation examines the internal consistency reliability and construct validity of the Pediatric Quality of Life Inventory™ (PedsQL™) Brain Tumor Module.

Psychosocial service use and unmet need among recently diagnosed adolescent and young adult cancer patients

PURPOSE To estimate the prevalence of fatigue, identify the factors associated with fatigue, and to explore the relationship between fatigue and quality of life (QOL) in long-term survivors of childhood acute lymphoblastic leukemia (ALL). METHODS One hundred sixty-one ALL survivors diagnosed at Childrens Hospital Los Angeles (Los Angeles, CA) before age 18 years and between January 1, 1975 and December 31, 1995, participated in a structured telephone interview. Participants were aged 18 to 41 years and off treatment for an average of 14 years. Four measures of fatigue, including the Revised-Piper Fatigue Scale, were used to assess fatigue; depression was assessed using the Center for Epidemiological Studies Depression Scale. Multivariate logistic regression models were developed to identify factors associated with fatigue and depression. RESULTS Prevalence of fatigue (30%) fell within the general population normal limits. Fatigue and depression were highly correlated (Pearson r = 0.75). Fatigue was associated with marriage (OR = 0.11; 95% CI, 0.02 to 0.50), having children (OR = 5.80; 95% CI, 1.30 to 25.82), sleep disturbances (OR = 6.15; 95% CI, 2.33 to 16.22), pain (OR = 5.56; 95% CI, 2.13 to 14.48), obesity (OR = 3.80; 95% CI, 1.41 to 10.26), cognitive impairment (OR = 2.56; 95% CI, 1.02 to 6.38), and exercise-induced symptoms (OR = 2.98; 95% CI, 1.11 to 8.02). Four factors associated with fatigue were also associated with depression: sleep disturbances, pain, obesity, and cognitive impairment. Fatigue was inversely related to QOL. CONCLUSION Some survivors of childhood ALL experience fatigue many years after treatment. Fatigued survivors represent a high-risk subgroup as they report more depression and poorer QOL than non-fatigued survivors and their peers.

Individual Prediction of Heart Failure Among Childhood Cancer Survivors

Adolescents and young adults (AYAs) with cancer demonstrate biomedical risks and psychosocial issues distinct from those of children or older adults. In this study, the authors examined and compared the extent to which AYAs treated in pediatric or adult oncology settings reported use of, and unmet need for, psychosocial support services.

Perceived Positive Impact of Cancer Among Long-term Survivors of Childhood Cancer: a report from the Childhood Cancer Survivor Study

PURPOSE To create clinically useful models that incorporate readily available demographic and cancer treatment characteristics to predict individual risk of heart failure among 5-year survivors of childhood cancer. PATIENTS AND METHODS Survivors in the Childhood Cancer Survivor Study (CCSS) free of significant cardiovascular disease 5 years after cancer diagnosis (n = 13,060) were observed through age 40 years for the development of heart failure (ie, requiring medications or heart transplantation or leading to death). Siblings (n = 4,023) established the baseline population risk. An additional 3,421 survivors from Emma Childrens Hospital (Amsterdam, the Netherlands), the National Wilms Tumor Study, and the St Jude Lifetime Cohort Study were used to validate the CCSS prediction models. RESULTS Heart failure occurred in 285 CCSS participants. Risk scores based on selected exposures (sex, age at cancer diagnosis, and anthracycline and chest radiotherapy doses) achieved an area under the curve of 0.74 and concordance statistic of 0.76 at or through age 40 years. Validation cohort estimates ranged from 0.68 to 0.82. Risk scores were collapsed to form statistically distinct low-, moderate-, and high-risk groups, corresponding to cumulative incidences of heart failure at age 40 years of 0.5% (95% CI, 0.2% to 0.8%), 2.4% (95% CI, 1.8% to 3.0%), and 11.7% (95% CI, 8.8% to 14.5%), respectively. In comparison, siblings had a cumulative incidence of 0.3% (95% CI, 0.1% to 0.5%). CONCLUSION Using information available to clinicians soon after completion of childhood cancer therapy, individual risk for subsequent heart failure can be predicted with reasonable accuracy and discrimination. These validated models provide a framework on which to base future screening strategies and interventions.

Psychological distress and unsatisfied need for psychosocial support in adolescent and young adult cancer patients during the first year following diagnosis.

Investigations examining psychosocial adjustment among childhood cancer survivors have focused primarily on negative effects and psychopathology. Emergent literature suggests the existence of positive impact or adjustment experienced after cancer, as well. The purpose of this study is to examine the distribution of Perceived Positive Impact (PPI) and its correlates in young adult survivors of childhood cancer.
