Psychological Symptoms, Social Outcomes, Socioeconomic Attainment, and Health Behaviors Among Survivors of Childhood Cancer: Current State of the Literature

The diagnosis, treatment, and medical late effects of childhood cancer may alter the psychosocial trajectory of survivors across their life course. This review of the literature focuses on mental health symptoms, achievement of social milestones, socioeconomic attainment, and risky health behaviors in survivors of childhood cancer. Results suggest that although most survivors are psychologically well adjusted, survivors are at risk for anxiety and depression compared with siblings. Although the absolute risk of suicide ideation and post-traumatic stress symptoms is low, adult survivors are at increased risk compared with controls. Moreover, young adult survivors are at risk for delayed psychosexual development, lower rates of marriage or cohabitation, and nonindependent living. Survivors' socioeconomic attainment also is reduced, with fewer survivors graduating college and gaining full-time employment. Despite risk for late health-related complications, survivors of childhood cancer generally engage in risky health behaviors at rates similar to or only slightly lower than siblings and peers. CNS tumors and CNS-directed therapies are salient risk factors for poor psychosocial outcomes. In addition, physical health morbidities resulting from cancer-directed therapies are associated with worse psychosocial functioning. Several studies support the effectiveness of cognitive and behavioral interventions to treat psychological symptoms as well as to modify health behaviors. Additional randomized controlled trials are needed to evaluate the efficacy and long-term outcomes of intervention efforts. Future research should focus on the identification of potential genetic predispositions related to psychosocial outcomes to provide opportunities for preventive interventions among survivors of childhood cancer.

Patient factors associated with sperm cryopreservation among at-risk adolescents newly diagnosed with cancer

BACKGROUND

Although survivors of adolescent-onset cancers are at risk of infertility, the majority desire children. Fertility preservation options are available for adolescents, but sperm banking remains underused. To the authors' knowledge, patient factors that influence decisions to bank sperm are poorly understood.

METHODS

A cross-sectional study of 146 adolescent males who were newly diagnosed with cancer and who completed surveys within 1 week of treatment initiation was performed. Participants, 65% of whom were white, were aged 13 to 21 years (mean, 16.49 years; standard deviation, 2.02 years) and were at risk of infertility secondary to impending gonadotoxic treatment. Participating institutions included 8 leading pediatric oncology centers across the United States and Canada.

RESULTS

Of the patients approached, approximately 80.6% participated. Parent recommendation to bank (odds ratio [OR], 4.88; 95% confidence interval [95% CI], 1.15-20.71 [P = .03]), higher Tanner stage (OR, 4.25; 95% CI, 1.60-11.27 [P < .01]), greater perceived benefits (OR, 1.41; 95% CI, 1.12-1.77 [P < .01]), and lower social barriers to banking (OR, 0.88; 95% CI, 0.81-0.96 [P < .01]) were found to be associated with adolescent collection attempts, whereas meeting with a fertility specialist (OR, 3.44; 95% CI, 1.00-11.83 [P = .05]), parent (OR, 3.02; 95% CI, 1.12-8.10 [P = .03]) or provider (OR, 2.67; 95% CI, 1.05-6.77 [P = .04]) recommendation to bank, and greater adolescent self-efficacy to bank (OR, 1.16; 95% CI, 1.01-1.33 [P = .03]) were found to be associated with successful sperm banking.

CONCLUSIONS

Adolescents' perceived benefits of sperm banking, higher Tanner stage, and parent recommendation were associated with collection attempts, whereas perceived social barriers decreased this likelihood. Successful banking was associated with greater adolescent self-efficacy, parent and provider recommendation to bank, and consultation with a fertility specialist. Providers should consult with both adolescents and parents regarding fertility preservation, and interventions should be tailored to address barriers to sperm banking while promoting its benefits.

Marijuana/tobacco use and patient-reported outcomes (PROs) in adult survivors of childhood cancer

175

Background: In 2017, the National Academy of Medicine reported adverse physical and psychosocial outcomes associated with marijuana use, and an increased risk of marijuana use among those who use tobacco. However, the association of marijuana and/or tobacco use with PROs has not been well-studied in survivors of childhood cancer. Methods: A random sample (stratified on self-reported smoking status) of 287 adult survivors of childhood cancer was selected from the St. Jude Lifetime Cohort Study. Chemotherapy and radiotherapy were abstracted from medical records. Marijuana use was self-reported and classified as past/current vs. never use. Current tobacco use was determined using serum cotinine concentrations by liquid chromatography tandem mass spectrometry. PROs were evaluated by physical and mental component summary (PCS and MCS) scores from the Medical Outcomes Study SF-36. Linear regression was used to evaluate associations of marijuana and tobacco use with PROs after adjusting for covariates, and the results were stratified by treatment modality. Results: Survivors’ mean age at study participation was 33.6 years (SD = 9.1), mean years from diagnosis was 24.2 (SD = 6.2). 61.3% used marijuana and 39.4% were current tobacco users. 79.3% of the tobacco users had marijuana use. Marijuana and tobacco were independently associated with lower PCS (βs = -3.1 and -2.9, respectively, p’s < 0.05) and MCS (βs = -3.3 and -3.2, respectively, p’s < 0.01). Among survivors who received chemotherapy, marijuana and tobacco were associated with lower PCS (β = -4.3, p < 0.01; β = -2.8, p < 0.05, respectively) and MCS (βs = -4.8 and -3.1, respectively, p’s < 0.05). In survivors who received radiotherapy, marijuana, but not tobacco, use was associated with lower PCS (β = -3.6, p < 0.05) and MCS (β = -4.6, p < 0.05). Among those who received neither chemotherapy nor radiotherapy, each substance was independently associated, but not significantly, with lower PCS and MCS. Conclusions: Among adult survivors of childhood cancer, marijuana users likely co-used tobacco, and both substances were independently associated with lower PROs. When associations with treatment exposures were assessed, different profiles of PRO scores were identified.

Psychosexual functioning in sexually active female survivors of childhood cancer

136

Background: Childhood cancer survivors (CCS) may be at risk for low psychosexual function. We estimated the prevalence of low psychosexual function among female CCS, and evaluated associations with treatment exposures. Methods: 712 female CCS (mean age at assessment 31.2±7.71 years, at diagnosis 7.00±5.58 years; 31.3% acute lymphoblastic leukemia, 12.5% Hodgkin lymphoma) and 122 non-cancer controls enrolled in the St. Jude Lifetime Cohort Study completed a clinical assessment, reported sexual activity with or without a partner in the preceding month, and filled out the Sexual Functioning Questionnaire (SFQ) (25 items averaged to create overall and subscale scores ranging 0-5; lower is worse). CCS with SFQ scores < 10th percentile of controls were classified as low function. Linear models, adjusted for age, were used to compare SFQ scores. Associations between CCS characteristics and psychosexual function were evaluated using logistic regression. Results: 19.9% of CCS had low psychosexual function with a lower mean overall SFQ score than controls (3.19 vs. 3.47, effect size 0.4; p < 0.01). The most common impairments among CCS were performance problems (27.4%), orgasm (24.2%), satisfaction (17.6%), interest (17.2%), desire (15.4%), and arousal (12.5%). Survivors with low function reported poor quality of life in both physical (21.1% vs. 12.7%, p = 0.01) and mental health (36.5% vs. 18.2%, p < 0.01) domains compared to those without. Untreated hypogonadism was associated with low function (OR 3.20, 95% CI 1.69-6.42) for the performance problems subscale. Compared to controls, CCS with germ cell tumors (OR 8.82, 95% CI 3.17-24.50), renal tumors (OR 4.49, 95% CI 1.89-10.67) and leukemia (OR 3.09, 95% CI 1.50-6.38) were at greatest risk for low function. Though 40.7% of CCS perceived a higher risk for low psychosexual function compared to other women their age, only 2.9% reported receiving an intervention. Conclusions: Low psychosexual function is prevalent among female CCS. CCS with low psychosexual function also report poorer quality of life and more psychological symptoms. Research is necessary to identify additional risk factors that characterize high-risk survivors who would benefit from targeted screening and intervention.

Factors influencing risk-based care of the childhood cancer survivor in the 21st century

The population of adult survivors of childhood cancer continues to grow as survival rates improve. Although it is well established that these survivors experience various complications and comorbidities related to their malignancy and treatment, this risk is modified by many factors that are not directly linked to their cancer history. Research evaluating the influence of patient-specific demographic and genetic factors, premorbid and comorbid conditions, health behaviors, and aging has identified additional risk factors that influence cancer treatment-related toxicity and possible targets for intervention in this population. Furthermore, although current long-term follow-up guidelines comprehensively address specific therapy-related risks and provide screening recommendations, the risk profile of the population continues to evolve with ongoing modification of treatment strategies and the emergence of novel therapeutics. To address the multifactorial modifiers of cancer treatment-related health risk and evolving treatment approaches, a patient-centered and risk-adapted approach to care that often requires a multidisciplinary team approach, including medical and behavioral providers, is necessary for this population.

Fertility-Related Perceptions and Impact on Romantic Relationships Among Adult Survivors of Childhood Cancer

PURPOSE

To present an overview of fertility-related perceptions and describe the perceived negative/positive impact of (potential) infertility on romantic relationships among childhood cancer survivors.

METHODS

Male and female long-term childhood cancer survivors (N = 92) aged 22-43 and 7-37 years postdiagnosis, completed an online survey about fertility-related perceptions (i.e., knowledge, beliefs, uncertainty, concern, and attitudes toward testing) and romantic relationships. Potential differences based on sociodemographic/cancer-specific factors were tested.

RESULTS

Most survivors (82.4%, n = 75) knew about infertility risk due to childhood cancer treatment. Seventy percent (n = 65) reported being told they were personally at risk, but less than one-third believed it (29.2%, n = 19/65). Half of survivors (48.9%, n = 45) never underwent fertility testing and were unaware of their fertility status. Fertility-related uncertainty and concerns were more common among survivors without children and those who desired (additional) children (d's > 0.5). Among survivors without biological children (n = 52), partnered survivors felt more uncertain about their fertility than singles (d = 0.8). Ten survivors (10.9%) reported a negative impact of infertility on romantic relationships, 6 (6.5%) reported a positive impact, and 7 (7.6%) reported both (e.g., pressure on relationship, fights, break-ups, being closer, and open partner communication).

CONCLUSIONS

Fertility-related perceptions varied among survivors, but the majority never underwent fertility testing. Uncertainty or concerns differed by current circumstances (e.g., wanting children and relationship status). Providers should routinely discuss potential infertility and offer testing throughout survivorship. A negative impact on romantic relationships may seem small, but should be considered for survivors who desire children and may discover they are infertile in the future.

Accurate understanding of infertility risk among families of adolescent males newly diagnosed with cancer

OBJECTIVE

To examine patient and parent understanding of infertility risk (relative to oncologists' risk ratings) among adolescents newly diagnosed with cancer, and to identify background factors related to inaccurate reporting/estimating.

METHODS

Male patients (N = 137; aged 13-21) and their parents completed self-report questionnaires. Those who reported a fertility-related conversation with their provider (N = 102 adolescents, N = 74 parents) reported their infertility risk (ie, what oncologist had communicated) and all participants' estimated risk (ie, personal belief). Reports/estimates were compared with oncologists' ratings to assess relative accuracy, and regression analyses assessed potentially related background factors.

RESULTS

Participants' agreement of their risk reports with the oncologist was poor (κ = .079/.122 for adolescents/parents), resulting in most adolescents (59.8%) and parents (58.7%) inaccurately reporting risk. Older adolescents were less likely to overreport risk (OR = 0.69; 95% CI, 0.49-0.97) and parents of sons with the highest Tanner stage were less likely to underreport (OR = 0.28; 95% CI, 0.08-0.92). Risk estimates were also in poor agreement with oncologists' ratings among adolescents (κ = .040) and parents (κ = .088). Accordingly, incongruent estimates occurred in most adolescents (63.7%) and parents (62.2%), although all reported fertility-related conversations with their providers.

CONCLUSIONS

Most adolescents and parents inaccurately reported infertility risk, and more poorly estimated risk. Research is needed to identify additional factors associated with accurate understanding of cancer-related infertility risk. Providers should be supported with user-friendly educational tools to promote awareness of infertility risk.

Parental influences on sperm banking attempts among adolescent males newly diagnosed with cancer

OBJECTIVE

To investigate the influence of parental sociodemographic, communication, and psychological factors on sperm collection attempts among at-risk adolescent males newly diagnosed with cancer.

DESIGN

Prospective, single group, observational study design.

SETTING

Pediatric oncology centers.

PATIENT(S)

Parents (N = 144) of 122 newly diagnosed adolescent males at increased risk for infertility secondary to cancer therapy.

INTERVENTION(S)

Survey-based assessment of parent factors associated with adolescent collection attempts.

MAIN OUTCOME MEASURE(S)

Attempt of manual collection of sperm.

RESULT(S)

Parental recommendation to bank sperm (odds ratio [OR] 3.72; 95% confidence interval [CI] 1.18-11.76) and perceived self-efficacy to facilitate banking (OR 1.20; 95% CI 1.02-1.41) were associated with an increased likelihood of making a collection attempt.

CONCLUSION(S)

Parental recommendation to bank is a critical influence for sperm banking among adolescent males newly diagnosed with cancer. These findings highlight the importance of effective communication between parents, patients, and health-care teams when discussing preservation options. Parent perceptions of their ability to facilitate sperm banking at the time of diagnosis should also be targeted in future interventions.

St. Jude Cancer Education for Children Program: The Impact of a Teacher-Led Intervention on Student Knowledge Gains

In 2006, St. Jude Children's Research Hospital (Memphis, Tennessee) began developing a school-based outreach program known as the St. Jude Cancer Education for Children Program (SJCECP). The aim of this program is to teach Memphis-area children about cells, cancer, and healthy habits that can prevent the development of cancer in adulthood. Initial plans for delivery of the program was for St. Jude staff to present the program at local schools. This plan for disseminating instruction was not feasible due to the limited availability of St. Jude staff. As a next step, during the 2012-2014 academic years, we conducted a study entitled SJCECP2, utilizing the SJCECP curriculum, with the objective of evaluating the impact of the educational intervention on knowledge acquisition and retention among fourth-grade students participating in a modified, teacher-led version of the program. Eighteen teachers and 426 students from 10 local schools in the greater Memphis area participated in the program evaluation. This study used a single-group, pre-test/post-test design to determine the impact of the SJCECP intervention on changes in knowledge scores among fourth-grade students. Testing was on cells, cancer, and healthy living. The mean scores increased from 6.45 to 8.12, 5.99 to 7.65, and 5.92 to 7.96 on cell, cancer, and health behaviors units, respectively (all p values <.001). Preliminary evidence suggests that the SJCECP2 intervention is a useful tool for teachers to improve student knowledge of knowledge of cells, cancer, and healthy living concepts at the fourth-grade level.

Prevalence and Predictors of Sperm Banking in Adolescents Newly Diagnosed With Cancer: Examination of Adolescent, Parent, and Provider Factors Influencing Fertility Preservation Outcomes

Purpose To estimate the prevalence of sperm banking among adolescent males newly diagnosed with cancer and to identify factors associated with banking outcomes. Patients and Methods A prospective, single-group, observational study design was used to test the contribution of sociodemographic, medical, psychological/health belief, communication, and developmental factors to fertility preservation outcomes. At-risk adolescent males (N = 146; age 13.00 to 21.99 years; Tanner stage ≥ 3), their parents, and medical providers from eight leading pediatric oncology centers across the United States and Canada completed self-report questionnaires within 1 week of treatment initiation. Multivariable logistic regression was used to calculate odds ratios (ORs) and 95% CIs for specified banking outcomes (collection attempt v no attempt and successful completion of banking v no banking). Results Among adolescents (mean age, 16.49 years; standard deviation, 2.02 years), 53.4% (78 of 146) made a collection attempt, with 43.8% (64 of 146) successfully banking sperm (82.1% of attempters). The overall attempt model revealed adolescent consultation with a fertility specialist (OR, 29.96; 95% CI, 2.48 to 361.41; P = .007), parent recommendation to bank (OR, 12.30; 95% CI, 2.01 to 75.94; P = .007), and higher Tanner stage (OR, 5.42; 95% CI, 1.75 to 16.78; P = .003) were associated with an increased likelihood of a collection attempt. Adolescent history of masturbation (OR, 5.99; 95% CI, 1.25 to 28.50; P = .025), banking self-efficacy (OR, 1.23; 95% CI, 1.05 to 1.45; P = .012), and parent (OR, 4.62; 95% CI, 1.46 to 14.73; P = .010) or medical team (OR, 4.26; 95% CI, 1.45 to 12.43; P = .008) recommendation to bank were associated with increased likelihood of sperm banking completion. Conclusion Although findings suggest that banking is underutilized, modifiable adolescent, parent, and provider factors associated with banking outcomes were identified and should be targeted in future intervention efforts.

Posttraumatic stress-related psychological functioning in adult survivors of childhood cancer

PURPOSE

The majority of research examining posttraumatic stress symptoms/disorder (PTSS/PTSD) among adult survivors of childhood cancer has been oriented to cancer, assuming that cancer has been the most traumatic experience in their lives. Whether that assumption is valid, and how it might impact assessment of PTSS, is unknown.

METHODS

Survivors in the St. Jude Lifetime Cohort study completed an assessment of PTSS without cancer orientation, global psychological functioning, perceived stress, and cancer-related anxiety.

RESULTS

Participants (n = 2969; M_age = 32.5 ± 8.5 years, 24.1 years since diagnosis, 49.1% female) obtained a mean score on the PTSD Checklist of 27.7, which is comparable to a normative population. Using established cutoffs, 11.8% obtained scores in the at-risk range. Multivariable modeling indicated that psychological factors [global distress (p < 0.0001), perceived stress (p = 0.001), cancer-related anxiety (p < 0.0001)] and demographic variables [female gender (p < 0.0001), survivors with less than a college education (p = 0.002)] were risk factors for increased PTSS. Only 14.5% identified a cancer-related traumatic event, and there was no difference in PTSS scores between those who identified cancer vs. non-cancer events as most stressful (28.4 ± 12.6 vs. 28.5 ± 12.7, p = 0.93).

CONCLUSION

One in eight adult long-term survivors of childhood cancer had PTSS above the cutoff, though subgroups (e.g., females and those with lower education) report more distress symptoms. Most adult survivors do not identify cancer as their most stressful event.

IMPLICATIONS FOR CANCER SURVIVORS

Screening for distress in survivorship clinics should not assume that distress is directly related to the survivor's cancer experience.

Human Papillomavirus Vaccination Rates in Young Cancer Survivors

Purpose

Cancer survivors are at high risk for human papillomavirus (HPV)-related morbidities; we estimated the prevalence of HPV vaccine initiation in cancer survivors versus the US population and examined predictors of noninitiation.

Methods

Participants included 982 cancer survivors (9 to 26 years of age; 1 to 5 years postcompletion of therapy); we assessed HPV vaccine initiation, sociodemographic and clinical characteristics, and vaccine-specific health beliefs; age-, sex-, and year-matched US population comparisons were from the National Immunization Survey-Teen and the National Health Interview Survey (2012-2015).

Results

The mean age at the time of the study was 16.3 ± 4.7 years; the mean time off therapy was 2.7 ± 1.2 years; participants were 55% male and 66% non-Hispanic white; 59% had leukemia/lymphoma. Vaccine initiation rates were significantly lower in cancer survivors versus the general population (23.8%; 95% CI, 20.6% to 27.0% v 40.5%; 95% CI, 40.2% to 40.7%; P < .001); survivors were more likely to be HPV vaccine-naïve than general population peers (odds ratio [OR], 1.72; 95% CI, 1.41 to 2.09; P < .001). Initiation in adolescent survivors (ages 13 to 17 years) was 22.0% (95% CI, 17.3% to 26.7%), significantly lower than population peers (42.5%; 95% CI, 42.2% to 42.8%; P < .001). Initiation in young adult survivors and peers (ages 18 to 26 years) was comparably low (25.3%; 95% CI, 20.9% to 29.7% v 24.2%; 95% CI, 23.6% to 24.9%). Predictors of noninitiation included lack of provider recommendation (OR, 10.8; 95% CI, 6.5 to 18.0; P < .001), survivors' perceived lack of insurance coverage for HPV vaccine (OR, 6.6; 95% CI, 3.9 to 11.0; P < .001), male sex (OR, 2.9; 95% CI, 1.7 to 4.8; P < .001), endorsement of vaccine-related barriers (OR, 2.7; 95% CI, 1.6 to 4.6; P < .001), and younger age (9 to 12 years; OR, 3.7; 95% CI, 1.8-7.6; P < .001; comparison, 13 to 17 years).

Conclusion

HPV vaccine initiation rates in cancer survivors are low. Lack of provider recommendation and barriers to vaccine receipt should be targeted in vaccine promotion efforts.

Premature Ovarian Insufficiency in Childhood Cancer Survivors: A Report From the St. Jude Lifetime Cohort

CONTEXT

Long-term follow-up data on premature ovarian insufficiency (POI) in childhood cancer survivors are limited.

OBJECTIVE

To describe the prevalence of POI, its risk factors, and associated long-term adverse health outcomes.

DESIGN

Cross-sectional.

SETTING

The St. Jude Lifetime Cohort Study, an established cohort in a tertiary care center.

PATIENTS

Nine hundred twenty-one participants (median age, 31.7 years) were evaluated at a median of 24.0 years after cancer diagnosis.

MAIN OUTCOME MEASURE

POI was defined by persistent amenorrhea combined with a follicle-stimulating hormone level >30 IU/L before age 40. Multivariable Cox regression was used to study associations between demographic or treatment-related risk factors and POI. Multivariable logistic regression was used to study associations between POI and markers for cardiovascular disease, bone mineral density (BMD), and frailty. Exposure to alkylating agents was quantified using the validated cyclophosphamide equivalent dose (CED).

RESULTS

The prevalence of POI was 10.9%. Independent risk factors for POI included ovarian radiotherapy at any dose and CED ≥8000 mg/m2. Patients with a body mass index ≥30 kg/m2 at the time of the St. Jude Lifetime Cohort assessment were less likely to have a diagnosis of POI. Low BMD and frailty were independently associated with POI.

CONCLUSION

High-dose alkylating agents and ovarian radiotherapy at any dose are associated with POI. Patients at the highest risk should be offered fertility preservation whenever feasible. POI contributes to poor general health outcomes in childhood cancer survivors; further studies are needed to investigate the role of sex hormone replacement in improving such outcomes.

The role of body image dissatisfaction in the association between treatment-related scarring or disfigurement and psychological distress in adult survivors of childhood cancer

OBJECTIVE

To examine the potential mediating role of body image dissatisfaction on the association between treatment-related scarring/disfigurement and psychological distress in adult survivors of childhood cancer.

METHODS

Participants included 1714 adult survivors of childhood cancer (mean [SD] age at evaluation = 32.4 [8.0] years, time since diagnosis = 24.1 [8.1] years) enrolled in the St. Jude Lifetime Cohort Study. Survivors completed measures of body image, emotional distress, and posttraumatic stress symptoms (PTSS). Body image dissatisfaction (BID) was categorized into 2 groups (cancer-related and general) based on factor analysis. Using causal mediation analysis, we estimated the proportion of psychological distress associated with treatment-related scarring/disfigurement that could be eliminated by resolving BID through a hypothetical intervention.

RESULTS

Among survivors with scarring/disfigurement of the head, a sizable proportion of the relative excess of psychological distress could be eliminated if BID was successfully treated (males: [cancer-related BID: depression: 63%; anxiety: 100%; PTSS: 52%]; [general BID: depression: 70%; anxiety: 100%; PTSS: 42%]; females: [cancer-related BID: depression: 20%; anxiety; 36%; PTSS: 23%]; [general BID: depression: 32%; anxiety: 87%; PTSS: 38%]). The mediating effect of BID was less pronounced for the association between scarring/disfigurement of the body and psychological distress for both males and females.

CONCLUSIONS

Body image dissatisfaction mediates the association treatment-related scarring/disfigurement and psychological distress among adult survivors of childhood cancer, particularly among survivors with scarring/disfigurement of the head and male survivors. Successful treatment of body image dissatisfaction has the potential to eliminate a substantial proportion of psychological distress related to scarring/disfigurement among adult survivors of childhood cancer.

Accuracy of self-reported smoking status in adult survivors of childhood cancer: A report from St. Jude Lifetime Cohort study

10570

Background: Although clinicians often evaluate smoking behavior in cancer survivors via self-report, the validity of this approach is unknown. We validated self-reported smoking status by serum cotinine data in clinically assessed adult survivors of childhood cancer and identified factors contributing to misclassification. Methods: The study sample consists of 287 randomly selected adult survivors of childhood cancers participating in the St. Jude Lifetime Cohort Study and undergoing a risk-based clinical assessment in a survivorship clinic. Self-reported smoking status was classified as never (N = 105), past (N = 111), and current (N = 71) smokers. Age, sex, and race/ethnicity were balanced among the three groups (p’s > 0.05). Blood samples were obtained and serum cotinine levels were quantified by liquid chromatography tandem mass spectrometry. Misclassification was determined by the discrepancies between self-reported smoking status and race/ethnicity-specific serum cotinine thresholds (Benowitz et al. Am J Epidemiol 2009). Multiple logistic regression model was used to identify factors related to misclassification. Results: Of the 287 survivors (mean age = 34 years [range = 19-61]; mean time from diagnosis = 24 years [range = 11-46]), 55.4% were male and 84.0% non-Hispanic white. Cotinine levels consistent with recent active smoking were present in 39.4% compared to 24.7% who self-reported as being a current smoker (X2= 14.1; p = 0.0002). Rates of misclassification were 36.9%, 8.4%, and 6.7% in survivors who reported themselves as past, current, and never smokers, respectively. Among self-reported past smokers, 18-30 years of age at survey, male, and current marijuana use increased the risk of misclassification: RR = 3.0 (95%CI = 1.2-7.6), 2.5 (95%CI = 1.1-5.4) and 3.2 (95%CI = 1.1-9.3), respectively. Conclusions: Within a clinical setting, reliance on self-report of smoking status by survivors results in a high misclassification rate. For research, serum cotinine levels should be utilized to assign smoking status. For clinical care and health promotion, clinicians need to be aware of the high rate of misclassification when relying upon self-reported smoking status.

Provider Influences on Sperm Banking Outcomes Among Adolescent Males Newly Diagnosed With Cancer

PURPOSE

The purpose of this study was to examine provider communication and sociodemographic factors which associate with sperm banking outcomes in at-risk adolescents newly diagnosed with cancer.

METHODS

A prospective single-group quasi-experimental study design was used to test the contributions of provider factors on sperm banking outcomes. Medical providers (N = 52, 86.5% oncologists) and 99 of their at-risk adolescent patients from eight leading pediatric oncology centers in North America completed questionnaires querying provider factors and patient sperm banking outcomes. Logistic regression with single covariates was used to test each provider factor as a potential correlate of the two binary sperm banking study outcomes (collection attempt/no attempt and successful sperm bank/no bank). Multicovariate logistic regression was used to calculate odds ratios (OR) and 95% confidence intervals (CIs) for specified banking outcomes.

RESULTS

Fertility referral (OR, 9.01; 95% CI, 2.54-31.90; p < .001) and provider comfort/skills in negotiating barriers to sperm banking with families (OR, 1.94; 95% CI, 1.03-3.63; p < .04) were associated with collection attempts. Adolescents who were referred for a specialized fertility consultation were also almost five times more likely to successfully bank (OR, 4.96; 95% CI, 1.54-16.00; p < .01) compared to those who were not.

CONCLUSIONS

Provider training in communicating/managing adolescents and their families about sperm banking, and increasing utilization of fertility preservation referrals, should increase the proportion of at-risk males preserving fertility before treatment initiation.

Long-term functional outcomes and quality of life in adult survivors of childhood extremity sarcomas: a report from the St. Jude Lifetime Cohort Study

PURPOSE

This study compared measured physical performance, health-related quality of life (HRQOL), and social role attainment between extremity sarcoma survivors and controls, and evaluated associations between disease and treatment exposures, health conditions, and performance measures.

METHODS

Survivors of extremity sarcoma from the St. Jude Lifetime cohort and controls frequency matched by age-, sex-, and race completed physical performance testing and questionnaires. Survivors with Z-scores on outcome measures ≤ -2.0 SD (compared to controls) were categorized with severe impairment/limitation.

RESULTS

Among 206 survivors (52.4 % male median age 36 years (range 19-65)), 37 % had low relative lean mass, 9.7 % had an ejection fraction <50 %, 51.5 % had diffusion capacity for carbon monoxide <75 %, 27.7 % had sensory and 25.2 % motor neuropathy, and 78.2 % had musculoskeletal complications. Severe impairments/limitations were present among ≥25 % of survivors on fitness, balance, and physical HRQOL measures, and among ≥15 % on strength and activity of daily living measures. Lower extremity tumor location (OR 8.23, 95 % CI 2.54-26.67, P value 0.0004) and amputation (OR 8.07, 95 % CI 3.06-21.27, P value <0.0001) were associated with poor fitness. Poor fitness was associated with increased odds of scoring <40 on the SF-36 physical component summary (OR 4.83, 95 % CI 1.95-11.99, P value 0.001) and role-physical subscale (OR 3.34, 95 % CI 1.33-8.43, P value 0.01). Survivors and controls had similar rates of marriage, independent living, employment, and college attendance.

CONCLUSIONS

Extremity sarcoma survivors experience high rates of physical impairment and report lower than expected physical HRQOL. However, they are as likely as peers to be married, live independently, be employed, and attend college.

IMPLICATIONS FOR CANCER SURVIVORS

Follow-up for extremity sarcoma survivors should include assessment of need for further orthopedic care and rehabilitation to address cardiopulmonary and musculoskeletal health.

The impact of childhood cancer: Perceptions of adult survivors

BACKGROUND

The objective of this study was to describe perceptions and associated risk factors of the impact of cancer on functional outcomes, including social relationships, exercise, finances, and religion, among adult survivors of childhood cancer.

METHODS

Evaluable participants included 3001 adult survivors (mean age, 32.5 years; range, 18.3-63.8 years; 24.1 years from diagnosis; 50.8% male; 84.9% Caucasian) who were enrolled in the St. Jude Lifetime Cohort study. Perceptions of the impact of cancer were assessed using the Brief Cancer Impact Assessment (BCIA). Regression models were used to evaluate risk factors for functional outcomes.

RESULTS

The median response on the BCIA was a perception that cancer had minimal impact on the domains assessed. Approximately 33.1% to 46.6% of survivors indicated this response across the 4 subscales, although responses ranged from very positive to very negative impact. Other than diagnosis (with survivors of brain tumors generally indicating a more negative impact of cancer, with subscale estimates of -1.25 for caregiving and finance and -1.01 for social and emotional and an odds ratio of 1.83 for exercise and diet), most variability was because of demographic factors, including sex, age, race, education, and employment.

CONCLUSIONS

The current findings highlight that many long-term adult survivors perceive minimal impact of childhood cancer on functional aspects of adulthood, including caregiving, finances, exercise, social-emotional relationships, and religion. This suggests that survivors may not be focusing on the influence of likely physical and psychological late effects of their disease in their day-to-day lives. For those who do perceive a negative impact, variability in responses suggests that there are of survivors who may benefit from interventions focused on the achievement of functional goals.

Approach for Classification and Severity Grading of Long-term and Late-Onset Health Events among Childhood Cancer Survivors in the St. Jude Lifetime Cohort

Characterization of toxicity associated with cancer and its treatment is essential to quantify risk, inform optimization of therapeutic approaches for newly diagnosed patients, and guide health surveillance recommendations for long-term survivors. The NCI Common Terminology Criteria for Adverse Events (CTCAE) provides a common rubric for grading severity of adverse outcomes in cancer patients that is widely used in clinical trials. The CTCAE has also been used to assess late cancer treatment-related morbidity but is not fully representative of the spectrum of events experienced by pediatric and aging adult survivors of childhood cancer. Also, CTCAE characterization does not routinely integrate detailed patient-reported and medical outcomes data available from clinically assessed cohorts. To address these deficiencies, we standardized the severity grading of long-term and late-onset health events applicable to childhood cancer survivors across their lifespan by modifying the existing CTCAE v4.03 criteria and aligning grading rubrics from other sources for chronic conditions not included or optimally addressed in the CTCAE v4.03. This article describes the methods of late toxicity assessment used in the St. Jude Lifetime Cohort Study, a clinically assessed cohort in which data from multiple diagnostic modalities and patient-reported outcomes are ascertained.

Caregiver Sexual and HPV Communication Among Female Survivors of Childhood Cancer

Human papillomavirus (HPV) vaccination is recommended for all female survivors of childhood cancer; yet, it is underused. Parent-child sexual communication and health care provider recommendation for HPV vaccination influence familial vaccination decisions. However, caregivers may be less likely to discuss sexual health issues with survivors as compared to healthy peers. Therefore, this study compared mothers of daughters with/without history of childhood cancer on measures of sexual communication, HPV-specific communication, and health care provider recommendation for HPV vaccination, and examined the effects of sociodemographic and medical factors on these measures. There were no differences between mothers of survivors/noncancer survivors on the outcomes (Ps > .05). Among all mothers, daughter's age was associated with sexual communication (Ps < .05). Household income and daughter's age were associated with health care provider recommendation for vaccination (Ps < .05). Among mothers of survivors, daughter's age at diagnosis was associated with sexual communication, HPV-specific communication, and health care provider recommendation for vaccination (Ps < .05). Findings have implications for the role of health care providers as advocates for mother-daughter sexual communication and HPV vaccination, especially among survivors of childhood cancer.
