Purpose: To assess the prevalence and severity of neurocognitive impairment in adult survivors of pediatric CNS tumors and to examine associated treatment exposures. Patients and Methods: Participants included 224 survivors of CNS tumors who were treated at St Jude Children's Research Hospital (current median age [range], 26 years [19 to 53 years]; time from diagnosis, 18 years [11 to 42 years]) and completed neurocognitive testing. Information on cranial radiation therapy (CRT) doses and parameters of delivery were abstracted from medical records. The prevalence of severe impairment (ie, at least two standard deviations below normative mean) was compared across radiation treatment groups (no CRT, focal irradiation, craniospinal irradiation) using the χ² test. Log-binomial models were used to estimate risk ratios (RRs) and corresponding 95% CIs for severe impairment. Results: In multivariable models, craniospinal irradiation was associated with a 1.5- to threefold increased risk of severe impairment compared with no CRT (eg, intelligence: RR = 2.70; 95% CI, 1.37 to 5.34; memory: RR = 2.93; 95% CI, 1.69 to 5.08; executive function: RR = 1.74; 95% CI, 1.24 to 2.45). Seizures were associated with impaired academic performance (RR = 1.48; 95% CI, 1.02 to 2.14), attention (RR = 1.54; 95% CI, 1.12 to 2.13), and memory (RR = 1.44; 95% CI, 1.04 to 1.99). Hydrocephalus with shunt placement was associated with impaired intelligence (RR = 1.78; 95% CI, 1.12 to 2.82) and memory (RR = 1.42; 95% CI, 1.03 to 1.95). Differential follow-up time contributed to variability in prevalence estimates between survivors treated with older nonconformal and those treated with more contemporary conformal radiation therapy methods. Neurocognitive impairment was significantly associated with lower educational attainment, unemployment, and nonindependent living. Conclusion: Survivors of pediatric CNS tumors are at risk of severe neurocognitive impairment in adulthood. The prevalence of severe impairment is greater than expected in the general population, even in the absence of CRT, and is associated with disrupted attainment of adult social milestones.

This study investigated longitudinal patterns of psychological distress in adult survivors of childhood cancer. Participants included 4569 adult survivors in the Childhood Cancer Survivor Study Cohort (CCSS) who completed the Brief Symptom Inventory-18 on three occasions between 1994 and 2010. Longitudinal latent class analysis was used to identify discrete classes of psychological distress. Predictors of class membership were examined through logistic regression modelling with odds ratios (ORs) and 95% confidence intervals (CIs) reported. Survivors were a median of 39 years of age and 30 years from diagnosis at the most recent follow-up. Most survivors reported few or no symptoms of distress over time, although subsets of survivors reported persistently elevated (depression: 8.9%; anxiety: 4.8%; somatisation: 7.2%) or significant increases in distress symptoms over the follow-up period (depression: 10.2%; anxiety: 11.8%; somatisation: 13.0%). Increasing distress symptoms were predicted by survivor perception of worsening physical health over time (depression: OR=3.3; 95% CI=2.4–4.5; anxiety: OR=3.0; 95% CI=2.2–4.0; somatisation: OR=5.3; 95% CI=3.9–7.4). Persistent distress symptoms were also predicted by survivor perception of worsening physical health over time, as well as by worsening pain and ending analgesic use. Subgroups of adult survivors are at-risk for chronic distress or significant increases in distress decades following their original cancer diagnosis. Routine screening of psychological distress in adult survivors of childhood cancer is warranted, especially for survivors who experience physical health morbidities.

The diagnosis of cancer during adolescent and young adulthood (AYA) may alter the development and psychological trajectory of survivors across their lifespan. The current review focuses broadly on emotional health, social functioning, health behaviors, and cancer-related cognitive impairment (CRCI) among AYA survivors. Overall, AYA survivors appear to be at elevated risk of emotional distress symptoms, mood and anxiety disorders, suicide, and mental health care service utilization compared with individuals without a cancer history. Difficulties with social relationships and reduced achievement of expected social outcomes including educational attainment and employment have been reported. Despite risk for health-related morbidities, including subsequent neoplasms, many AYA survivors do not engage in health behaviors at the recommended levels for physical activity, diet, or tobacco and alcohol use. Although CRCI has not been comprehensively characterized in this population, subgroups of AYA survivors appear to be at risk for experiencing CRCI, including survivors of central nervous system tumors, Hodgkin lymphoma, testicular, and breast cancer. Across each considered domain of psychological functioning, intervention efforts have largely focused on acceptability and feasibility with an increasing focus on e/mHealth approaches. Future research should include multiphase studies, including randomized controlled trials designed to evaluate intervention efficacy and effectiveness. It is imperative that psychological interventions consider the unique needs of AYA survivors by developmental stage and across multiple levels of influence (patient, support system, institution, and health care system).

Purpose: In the general population, psychological symptoms frequently co-occur; however, profiles of symptom comorbidities have not been examined among adolescent survivors of childhood cancer.Patients and Methods: Parents of 3,893 5-year survivors of childhood cancer who were treated between 1970 and 1999 and who were assessed in adolescence (age 12 to 17 years) completed the Behavior Problems Index. Age- and sex-standardized z scores were calculated for symptom domains by using the Childhood Cancer Survivor Study sibling cohort. Latent profile analysis identified profiles of comorbid symptoms, and multivariable multinomial logistic regression modeling examined associations between cancer treatment exposures and physical late effects and identified symptom profiles. Odds ratios (ORs) and 95% CIs for latent class membership were estimated and analyses were stratified by cranial radiation therapy (CRT; CRT or no CRT).Results: Four symptoms profiles were identified: no significant symptoms (CRT, 63%; no CRT, 70%); elevated anxiety and/or depression, social withdrawal, and attention problems (internalizing; CRT, 31%; no CRT, 16%); elevated headstrong behavior and attention problems (externalizing; CRT, no observed; no CRT, 9%); and elevated internalizing and externalizing symptoms (global symptoms; CRT, 6%; no CRT, 5%). Treatment with ≥ 30 Gy CRT conferred greater risk of internalizing (OR, 1.7; 95% CI, 1.0 to 2.8) and global symptoms (OR, 3.2; 95% CI, 1.2 to 8.4). Among the no CRT group, corticosteroid treatment was associated with externalizing symptoms (OR, 1.9; 95% CI, 1.2 to 2.8) and ≥ 4.3 g/m²intravenous methotrexate exposure was associated with global symptoms (OR, 1.5; 95% CI, 0.9 to 2.4). Treatment late effects, including obesity, cancer-related pain, and sensory impairments, were significantly associated with increased risk of comorbid symptoms.Conclusion: Behavioral, emotional, and social symptoms frequently co-occur in adolescent survivors of childhood cancer and are associated with treatment exposures and physical late effects. Assessment and consideration of symptom profiles are essential for directing appropriate mental health treatment for adolescent survivors.

BACKGROUND: Survivors of childhood cancer who are treated with platinum‐based chemotherapy and/or cranial radiation are at risk of treatment‐induced hearing loss. However, the effects of such hearing loss on adult social attainment have not been well elucidated.METHODS: Adult survivors of pediatric central nervous system (CNS) solid tumors (180 survivors) and non‐CNS solid tumors (226 survivors) who were treated with potentially ototoxic cancer therapy completed audiologic evaluations and questionnaires assessing their perception of social functioning and social attainment (ie, independent living, marriage, and employment). Audiograms were graded with the Chang ototoxicity grading scale. Analyses were stratified by tumor type (ie, CNS vs non‐CNS). Multivariable logistic regression models were conducted with adjustment for age; sex; chronic health conditions; and, for the CNS group, IQ. Adjusted odds ratios (ORs) and 95% confidence intervals (95% CIs) were reported.RESULTS: Serious hearing loss (that requiring a hearing aid or deafness) was detected in 36% of survivors of CNS tumors and 39% of survivors of non‐CNS tumors. Serious hearing loss was associated with an increased risk of perceived negative impact in ≥1 areas of social functioning (survivors of non‐CNS tumors: OR, 1.83 [95% CI, 1.00‐3.34]). Among survivors of non‐CNS tumors, serious hearing loss was associated with 2‐fold increased risk of nonindependent living (OR, 2.19; 95% CI, 1.19‐4.04) and unemployment or not graduating from high school (OR, 1.85; 95% CI, 1.00‐3.34).CONCLUSIONS: A substantial proportion of adult survivors of childhood cancer treated with potentially ototoxic therapy have serious hearing loss. Treatment‐induced hearing loss was found to be associated with reduced social attainment, both perceived and actual, in this study sample. Cancer 2015;121:4053–4061. © 2015 American Cancer Society.

BACKGROUND: Adult survivors of childhood cancer are at risk for suicide ideation, although longitudinal patterns and rates of recurrent suicide ideation are unknown. This study investigated the prevalence of late report (ie, after initial assessment) and recurrent suicide ideation in adult survivors of childhood cancer, identified predictors of suicide ideation, and examined associations among suicide ideation and mortality.METHODS: Participants included 9128 adult survivors of childhood cancer and 3082 sibling controls enrolled in the Childhood Cancer Survivor Study who completed a survey question assessing suicide ideation on one or more occasions between 1994 and 2010. Suicide ideation was assessed using the Brief Symptom Inventory‐18 instrument. Mortality data was ascertained from the National Death Index.RESULTS: Survivors were more likely to report late (odds ratio [OR] = 1.9, 95% confidence interval [CI] = 1.5‐2.5) and recurrent suicide ideation (OR = 2.6, 95% CI = 1.8‐3.8) compared to siblings. Poor physical health status was associated with increased risk of suicide ideation in survivors (late report: OR = 1.9, 95% CI = 1.3‐2.7; recurrent: OR = 1.9, 95% CI = 1.2‐2.9). Suicide ideation was associated with increased risk for all‐cause mortality (hazard ratio = 1.3, 95% CI = 1.03‐1.6) and death by external causes (hazard ratio = 2.4, 95% CI = 1.4‐4.1).CONCLUSIONS: Adult survivors of childhood cancer are at risk for late‐report and recurrent suicide ideation, which is associated with increased risk of mortality. Routine screening for psychological distress in adult survivors appears warranted, especially for survivors who develop chronic physical health conditions.
