Reconsidering Physical Activity Restrictions for Mononephric Survivors of Childhood Cancer: A Report From the Children's Oncology Group.

Although traditional recommendations for mononephric childhood cancer survivors are to avoid contact sports in order to protect the remaining kidney, review of available evidence suggests that the majority of renal loss is caused by accidents not involving sports. An interdisciplinary team performed a review of the English literature published from 1999 to 2012 within the PubMed, Cochrane, Google Scholar, and National Guidelines Clearinghouse databases. The level of evidence and proposed recommendations were graded according to an established rubric and GRADE criteria. Our review found that kidney loss is most commonly caused by nonsports activities such as motor vehicle accidents and falls, implying that restrictions on sports-related activity in mononephric pediatric survivors are not well supported. This favors encouraging ordinary sports and related activities without restriction in mononephric childhood cancer survivors because the known benefits of exercise outweigh the exceedingly low risk of renal loss. Accordingly, activity recommendations for mononephric patients have been revised in the most current version of the Children's Oncology Group Long-term Follow-Up Guidelines for Survivors of Childhood, Adolescent and Young Adult Cancers. This has important implications for this and similar populations who may now undertake individual and organized sports without undue regard for their mononephric status.

Substance use among adolescent and young adult cancer survivors.

OBJECTIVE: Health-promoting behaviors are recommended to childhood cancer survivors (CCS) to reduce late effects resulting from cancer treatment. Understanding factors associated with substance use is needed, especially among Hispanic CCS who are underrepresented in previous studies. The objective of this study is to examine substance use behaviors of recently treated Hispanic and non-Hispanic CCS. METHODS: One hundred ninety-three Los Angeles County CCS who were diagnosed between 2000 and 2007 (54% Hispanic; mean age 19.9 years, SD = 2.8; mean age at diagnosis = 12.1, SD = 3.0; mean years since diagnosis = 7.8, SD = 2.0) provided self-reported information on substance use, demographics, clinical factors, religiosity, and depressive symptoms. Risk and protective factors for substance use were examined using multivariable logistic regression. RESULTS: Prevalence of 30-day substance use was 11%, 25%, and 14% for tobacco, alcohol, and marijuana, respectively. In controlled regression models, age was positively associated with tobacco use, binge drinking, and polysubstance use (use of at least two of the three substances). Male gender, higher depressive symptoms, and higher socioeconomic status were associated with greater marijuana use. In addition, religiosity was negatively associated with the use of all substances. CONCLUSIONS: The prevalence rates for substance use in this ethnically diverse representative sample of CCS are lower than those observed in the general population. Older CCS were at higher risk of substance use, and depression was associated with greater marijuana use. No differences by ethnicity were observed. Interventions for substance use prevention/cessation among CCS may be most effective if implemented before the age of 21 years and address mental health as part of survivorship care.

Comparative Toxicity by Sex Among Children Treated for Acute Lymphoblastic Leukemia: A Report From the Children's Oncology Group.

BACKGROUND: Epidemiologic studies find sex-based differences in incidence, survival, and long-term outcomes for children with cancer. The purpose of this study was to determine whether male and female patients differ with regard to acute treatment-related toxicities. PROCEDURES: We reviewed data collected on the Children's cancer group (CCG) high-risk acute lymphoblastic leukemia (ALL-HR) study (CCG-1961), and compared male and female patients' toxicity incidence and related variables in the first four phases of treatment. Similar analyses were performed with standard-risk ALL (ALL-SR) patients enrolled in CCG-1991. RESULTS: Among ALL-HR patients, females had significantly more hospital days, delays in therapy, grade 3 or 4 toxicities (e.g., gastrointestinal, liver), and supportive care interventions (e.g., transfusions, intravenous antibiotics) than males. Females were significantly more likely to have died of treatment-related causes than males (Hazard ratio = 2.8, 95%CI = 1.5-5.3, P = 0.002). Five months after beginning the treatment, the cumulative incidence of treatment-related deaths was 2.6% for females and 1.2% for males. Similar disparities were found among ALL-SR patients, with females experiencing significantly more hospital days and treatment-related toxicities than males. CONCLUSIONS: This study complements cancer survivorship studies that also report an increase in treatment-related late effects among females. Risk profiles appear to be different for male and female patients, with females having greater risk of developing both acute and long-term treatment-related toxicities. The underlying biological mechanisms for these sex differences are poorly understood and warrant further study in order to determine how sex-based outcome disparities can be addressed in future clinical trials and practice.

Cancer-related follow-up care among Hispanic and non-Hispanic childhood cancer survivors: The Project Forward study.

BACKGROUND: Follow-up care is critical for childhood cancer survivors (CCS), who are at high risk for comorbidities and late effects of cancer treatments. Understanding the factors associated with maintaining follow-up care is needed, especially for Hispanic CCS, who have been under-represented in previous studies. METHODS: Risk factors and protective factors for receiving cancer-related follow-up care were examined among 193 Los Angeles County CCS diagnosed between 2000 and 2007 (54% Hispanic; mean ± standard deviation age, 19.9 ± 2.8 years; age at diagnosis, 12.1 ± 3.0 years; time since diagnosis, 7.8 ± 2.0 years). Self-report surveys were used to assess follow-up care, insurance status, demographics, clinical factors, and psychosocial risk (eg, depression) and protective (eg, self-efficacy [SE]) factors. Multivariable logistic regression was used to identify factors associated with the previous receipt of cancer-related follow-up care (in prior 2 years) and the intent to seek future cancer-related follow-up care. RESULTS: Seventy-three percent of CCS reported a cancer follow-up visit in the previous 2 years, which was positively associated (P < .05) with having health insurance, white ethnicity (vs Hispanic), younger age, and greater treatment intensity. Sixty-nine percent reported an intent to receive follow-up care in the next 2 years, which was positively associated (P < .05) with having health insurance and greater SE. CONCLUSIONS: Hispanics and older CCS were more likely to lack previous follow-up care. Because health insurance was strongly associated with both previous follow-up care and the intent to seek care, the current results indicate that recent changes in health coverage may improve follow-up among CCS. Interventions targeting improved SE may help increase intent to receive follow-up care for this population.

The relationship between posttraumatic stress and posttraumatic growth among adolescent and young adult (AYA) cancer patients.

OBJECTIVE: Theories of posttraumatic growth suggest that some degree of distress is necessary to stimulate growth; yet, investigations of the relationship between stress and growth following trauma are mixed. This study aims to understand the relationship between posttraumatic stress symptoms and posttraumatic growth in adolescent and young adult (AYA) cancer patients. METHOD: 165 AYA patients aged 14-39 years at diagnosis completed standardized measures of posttraumatic stress and posttraumatic growth at 12 months following diagnosis. Locally weighted scatterplot smoothing and regression were used to examine linear and curvilinear relationships between posttraumatic stress and posttraumatic growth. RESULTS: No significant relationships between overall posttraumatic stress severity and posttraumatic growth were observed at 12-month follow-up. However, curvilinear relationships between re-experiencing (a posttraumatic stress symptom) and two of five posttraumatic growth indicators (New Possibilities, Personal Strengths) were observed. CONCLUSION: Findings suggest that re-experiencing is associated with some aspects of posttraumatic growth but not others. Although re-experiencing is considered a symptom of posttraumatic stress disorder, it also may represent a cognitive process necessary to achieve personal growth for AYAs. Findings call into question the supposed psychopathological nature of re-experiencing and suggest that re-experiencing, as a cognitive process, may be psychologically adaptive. Opportunities to engage family, friends, cancer survivors, or health care professionals in frank discussions about fears, worries, or concerns may help AYAs re-experience cancer in a way that enhances their understanding of what happened to them and contributes to positive adaptation to life after cancer.

Individual prediction of heart failure among childhood cancer survivors.

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 Children's 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.

PURPOSE: Identifying at-risk adolescent and young adult (AYA) cancer patients and referring them to age-appropriate psychosocial support services may be instrumental in reducing psychological distress and promoting psychosocial adaptation. The purpose of this study is to identify trajectories of clinically significant levels of distress throughout the first year following diagnosis and to distinguish factors, including supportive care service use, that predict the extent to which AYAs report distress. METHODS: In this prospective multisite study, 215 AYAs aged 15-39 years were assessed for psychological distress and psychosocial support service use within the first 4 months of diagnosis and again 6 and 12 months later. On the basis of distress scores, respondents were assigned to one of four distress trajectory groups (Resilient, Recovery, Delayed, and Chronic). Multiple logistic regression analyses examined whether demographics, clinical variables, and reports of unsatisfied need for psychosocial support were associated with distress trajectories over 1 year. RESULTS: Twelve percent of AYAs reported clinically significant chronic distress throughout the first 12 months following diagnosis. An additional 15% reported delayed distress. Substantial proportions of AYAs reported that needs for information (57%), counseling (41%), and practical support (39%) remained unsatisfied at 12 months following diagnosis. Not getting counseling needs met, particularly with regard to professional mental health services, was observed to be significantly associated with distress over time. CONCLUSIONS: Substantial proportions of AYAs are not utilizing psychosocial support services. Findings suggest the importance of identifying psychologically distressed AYAs and addressing their needs for mental health counseling throughout a continuum of care.

Adolescents' psychosocial health-related quality of life within 6 months after cancer treatment completion.

BACKGROUND: Health-related quality of life (HRQOL) may be affected by cure-directed therapy given to pediatric oncology patients. Identification of HRQOL risk/protective factors may facilitate the development of clinical interventions. OBJECTIVE: The study purpose was to assess adolescents' psychosocial HRQOL soon after treatment completion using patient-reported outcome measures. METHODS: Subjects were recruited from May 2005 to February 2007 to participate in a structured interview that collected information on demographics, symptoms, HRQOL (PedsQL 4.0), and coping (Adolescent Coping Orientation for Problem Strategies Questionnaire). Disease/treatment information was abstracted from medical records. Data analysis included descriptive approaches for data summarization and regression modeling for estimation and testing. RESULTS: A total of 94 participants were included in the analyses. Their mean psychosocial functioning summary scores fell between the means reported for healthy children and children with cancer; 18% were more than 1 standard deviation below the mean. In the univariate analyses, lower psychosocial HRQOL was associated with central nervous system tumors (P = .01), radiation therapy (P = .01), and treatment duration of 13 to 24 months (P < .01). Protective factors identified in multivariable analyses included older age and use of humor for coping; risk factors included symptoms of pain, fatigue, and posttraumatic stress. CONCLUSION: Although most patients rated their psychosocial HRQOL as good, a subset (18%) may have increased risk for impaired HRQOL. IMPLICATIONS FOR PRACTICE: Clinical assessment of psychosocial HRQOL using patient-reported outcome measures during the early posttreatment phase is recommended. Longitudinal studies are needed to further explore risk/protective factors and to identify targeted interventions to minimize the adverse psychosocial effects of cancer treatment and maximize healthy survivorship.

Trajectories of psychological distress in adolescent and young adult patients with cancer: a 1-year longitudinal study.

PURPOSE: To examine prevalence and changes in symptoms of psychological distress over 1 year after initial cancer diagnosis in adolescent and young adult (AYA) patients with cancer. Sociodemographic and clinical predictors of changes in distress were examined. PATIENTS AND METHODS: In this multisite, longitudinal, prospective study of an ethnically diverse sample, 215 patients age 14 to 39 years were assessed for psychological distress within the first 4 months of diagnosis and again 6 and 12 months later. Linear mixed models with random intercept and slope estimated changes in distress, as measured by the Brief Symptom Inventory-18 (BSI-18). RESULTS: Within the first 4 months of diagnosis, 60 respondents (28%) had BSI-18 scores suggesting caseness for distress. On average, distress symptoms exceeded population norms at the time of diagnosis, dipped at the 6-month follow-up, but increased to a level exceeding population norms at the 12-month follow-up. A statistically significant decline in distress over 1 year was observed; however, the gradient of change was not clinically significant. Multivariate analyses revealed that the reduction in distress over time was primarily a function of being off treatment and involved in school or work. Notably, cancer type or severity was not associated with distress. CONCLUSION: Findings emphasize the importance of early psychosocial intervention for distress in AYAs as well as the need to manage treatment-related symptoms and facilitate AYAs' involvement in work or school to the extent possible. Continued research is needed to understand how distress relates to quality of life, functional outcomes, treatment, and symptom burden throughout the continuum of care.

Post-traumatic growth among an ethnically diverse sample of adolescent and young adult cancer survivors.

OBJECTIVE: Although some survivors of childhood cancer report significant psychosocial distress, many also report having derived benefits, or post-traumatic growth (PTG), from their cancer experience. This study examines PTG and its correlates among an ethnically diverse sample of adolescent/young adult (AYA) cancer survivors who have recently completed treatment. METHODS: Survivors of childhood cancer (n = 94; 47% Hispanic), ages 11-21 and within 6 months of completing cancer therapy, were recruited from three pediatric cancer centers. Participants completed a structured interview that assessed demographics, PTG, post-traumatic stress symptoms, health-related quality of life, optimism, and depressive symptoms. Diagnosis/treatment information was collected from each patient's medical record. Multiple regression analyses were used to identify significant correlates of PTG. RESULTS: The majority of survivors reported positive growth. PTG was positively associated with psychosocial functioning and post-traumatic stress symptoms and inversely associated with physical functioning and depressive symptoms. PTG was significantly lower among survivors of bone tumors (vs. survivors of other cancers) and Hispanic survivors who primarily spoke English at home (vs. Hispanics who primarily spoke Spanish at home and non-Hispanics). PTG was not significantly related to age, sex, optimism, cancer treatment modality, duration of treatment, or treatment intensity. CONCLUSIONS: The AYA survivors commonly reported PTG in the immediate aftermath of cancer treatment. Findings regarding PTG among more acculturated Hispanic and bone tumor AYA survivors may help to inform risk-adapted clinical interventions, among those transitioning from active treatment to post-treatment surveillance, to mitigate negative long-term sequelae and enhance positive psychosocial adaptation from the cancer diagnosis and treatment.

Mental health disparities between Hispanic and non-Hispanic parents of childhood cancer survivors.

BACKGROUND: Parents of childhood cancer survivors (CCS) experience considerable distress related to their child's cancer. However, little is known about cultural variation in this experience. We examine parental distress, specifically symptoms of post-traumatic stress (PTSS) and depression, comparing Hispanic and non-Hispanic parents of CCS. PROCEDURE: Seventy-nine Hispanic and 60 non-Hispanic parents of CCS (currently aged 14-25, off treatment ≥2 years) completed questionnaires assessing demographics, depression, PTSS, perceived stress, and child's health status/quality of life (QOL). t-Tests and chi-square statistics were used to compare differences in demographic characteristics between Hispanic and non-Hispanic parents and multivariable regression was used to determine independent risk factors associated with parental PTSS and depression. RESULTS: Hispanic parents were significantly younger, had less education, lower incomes and reported significantly more PTSS and depressive symptoms than non-Hispanic parents (all P-values < 0.0001). Among Hispanic parents, foreign birthplace predicted higher PTSS after controlling for other factors (P < 0.001). Hispanic parents, regardless of birthplace, reported more depressive symptoms than non-Hispanic parents (US-born, P < 0.05; foreign-born, P < 0.01). For PTSS and depression, there were positive relationships with parental stress and negative relationships with the child's psychosocial QOL. Hispanic and non-Hispanic CCS did not differ significantly on disease and treatment factors or health-related QOL. CONCLUSIONS: Hispanic parents of CCS may be at greater risk for poorer mental health outcomes. Ethnic-specific factors (e.g., acculturation, immigration status, and previous trauma) may influence parents' responses and adjustment to their child's cancer. Research is needed to determine how to meet the needs of the most vulnerable parents.

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

BACKGROUND: 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. METHODS: Within 4 months of initial cancer diagnosis, 215 AYAs ages 14 to 39 years (99 from pediatric care settings and 116 from adult care settings; 75% response rate) were assessed for reporting use of information resources, emotional support services, and practical support services. Statistical analyses derived odds ratios and 95% confidence intervals for service use and unmet needs after controlling for race, employment/school status, sex, relationship status, severity of cancer, treatment, and treatment-related side effects. RESULTS: AYAs ages 20 to 29 years were significantly less likely than teens and older patients ages 30 to 39 years to report using professional mental health services and were significantly more likely to report an unmet need with regard to cancer information, infertility information, and diet/nutrition information. Compared with teens who were treated in pediatric facilities, AYAs who were treated in adult facilities were more likely to report an unmet need for age-appropriate Internet sites, professional mental health services, camp/retreats programs, transportation assistance, and complementary and alternative health services. CONCLUSIONS: Substantial proportions of AYAs are not getting their psychosocial care needs met. Bolstering psychosocial support staff and patient referral to community-based social service agencies and reputable Internet resources may enhance care and improve quality of life for AYAs.

Prevalence and predictors of post-traumatic stress symptoms in adolescent and young adult cancer survivors: a 1-year follow-up study.

OBJECTIVES: Post-traumatic stress symptoms (PTSS) have been identified as a meaningful indicator of distress in cancer survivors. Distinct from young adult survivors of childhood cancer, young people diagnosed with cancer as adolescents and young adults (AYAs) face unique psychosocial issues; however, there is little published research of PTSS in the AYA population. This study examines prevalence and predictors of PTSS among AYAs with cancer. METHODS: As part of a longitudinal study of AYAs with cancer, 151 patients aged 15-39 years completed mailed surveys at 6 and 12 months post-diagnosis. Severity of PTSS was estimated at 6 and 12 months post-diagnosis. Multiple regression analyses were conducted to investigate the predictive effects of socio-demographic and clinical characteristics on changes in PTSS over time. RESULTS: At 6 and 12 months, respectively, 39% and 44% of participants reported moderate to severe levels of PTSS; 29% had PTSS levels suggestive of post-traumatic stress disorder. No significant differences in severity of PTSS between 6 and 12 months were observed. Regression analyses suggested that a greater number of side effects were associated with higher levels of PTSS at 6 months. Currently receiving treatment, having surgical treatment, diagnosis of a cancer type with a 90-100% survival rate, remaining unemployed/not in school, and greater PTSS at 6 months were associated with higher levels of PTSS at 12 months. CONCLUSIONS: Post-traumatic stress symptoms were observed as early as 6 months following diagnosis and remained stable at 12-month follow-up. The development of early interventions for reducing distress among AYA patients in treatment is recommended.

Exercise recommendations for childhood cancer survivors exposed to cardiotoxic therapies: an institutional clinical practice initiative.

Childhood cancer survivors who have received treatment with anthracyclines are at risk for developing cardiomyopathy in dose-dependent fashion. Historically, restrictions on certain types of physical activity that were intended to preserve cardiac function have been recommended, based on a mixture of evidence-based and consensus-based recommendations. In the LIFE Cancer Survivorship & Transition Program at Children's Hospital Los Angeles, the authors reevaluated their recommendations for exercise in survivors who were exposed to anthracyclines, with or without irradiation in proximity to the myocardium. The primary goal was to develop consistent, specific, practical, safe, and (where possible) evidence-based recommendations for at-risk survivors in the program. To accomplish this, the authors referred to current exercise guidelines for childhood cancer survivors, consulted recent literature for relevant populations, and obtained input from the program's pediatric cardiology consultant. The resulting risk-based exercise recommendations are designed to complement current published guidelines, maximize safe exercise, and help childhood cancer survivors return to a normal life that emphasizes overall wellness and physical activity. This article describes a single institution's experience in modifying exercise recommendations for at-risk childhood survivors and includes the methods, findings, and current institutional practice recommendations along with sample education materials.

Cancer survivor identity shared in a social media intervention.

This study investigates how cancer survivors construct their identities and the impact on their psychological health, as measured by depression and survivor self-efficacy. Fourteen young adult survivors of pediatric cancer participated in a customized social networking and video blog intervention program, the LIFECommunity, over a 6-month period. Survivors were asked to share their stories on various topics by posting video messages. Those video blog postings, along with survey data collected from participants, were analyzed to see how cancer survivors expressed their identities, and how these identities are associated with survivors' psychosocial outcomes. In survivors who held negative stereotypes about cancer survivors, there was a positive relationship with depression while positive stereotypes had a marginal association with cancer survivor efficacy. Findings indicate that although pediatric cancer survivors often do not publicly discuss a "cancer survivor identity," they do internalize both positive and negative stereotypes about cancer survivorship. It is important for practitioners to be aware of the long-term implications of cancer survivor identity and stereotypes.

Fatigue, inflammation, and ω-3 and ω-6 fatty acid intake among breast cancer survivors.

PURPOSE: Evidence suggests that inflammation may drive fatigue in cancer survivors. Research in healthy populations has shown reduced inflammation with higher dietary intake of ω-3 polyunsaturated fatty acids (PUFAs), which could potentially reduce fatigue. This study investigated fatigue, inflammation, and intake of ω-3 and ω-6 PUFAs among breast cancer survivors. METHODS: Six hundred thirty-three survivors (mean age, 56 years; stage I to IIIA) participating in the Health, Eating, Activity, and Lifestyle Study completed a food frequency/dietary supplement questionnaire and provided a blood sample assayed for C-reactive protein (CRP) and serum amyloid A (30 months after diagnosis) and completed the Piper Fatigue Scale and Short Form-36 (SF-36) vitality scale (39 months after diagnosis). Analysis of covariance and logistic regression models tested relationships between inflammation and fatigue, inflammation and ω-3 and ω-6 PUFA intake, and PUFA intake and fatigue, controlling for three incremental levels of confounders. Fatigue was analyzed continuously (Piper scales) and dichotomously (SF-36 vitality ≤ 50). RESULTS: Behavioral (P = .003) and sensory (P = .001) fatigue scale scores were higher by increasing CRP tertile; relationships were attenuated after adjustment for medication use and comorbidity. Survivors with high CRP had 1.8 times greater odds of fatigue after full adjustment (P < .05). Higher intake of ω-6 relative to ω-3 PUFAs was associated with greater CRP (P = .01 after full adjustment) and greater odds of fatigue (odds ratio, 2.6 for the highest v lowest intake; P < .05). CONCLUSION: Results link higher intake of ω-3 PUFAs, decreased inflammation, and decreased physical aspects of fatigue. Future studies should test whether ω-3 supplementation may reduce fatigue among significantly fatigued breast cancer survivors.

Perceived positive impact of cancer among long-term survivors of childhood cancer: a report from the childhood cancer survivor study.

OBJECTIVE: 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. METHODS: 6425 survivors and 360 siblings completed a comprehensive health survey, inclusive of a modified version of the Post-traumatic Growth Inventory (PTGI) as a measure of PPI. Linear regression models were used to examine demographic, disease and treatment characteristics associated with PPI. RESULTS: Survivors were significantly more likely than siblings to report PPI. Endorsement of PPI was significantly greater among female and non-white survivors, and among survivors exposed to at least one intense therapy, a second malignancy or cancer recurrence. Survivors diagnosed at older ages and fewer years since diagnosis were more likely to report PPI. Income, education and marital/relationship status appeared to have varied relationships to PPI depending upon the subscale being evaluated. CONCLUSIONS: The existence and variability of PPI in survivors in this study suggest that individual characteristics, inclusive of race, gender, cancer type, intensity of treatment, age at diagnosis and time since diagnosis, have unique and specific associations with different aspects of perceived positive outcomes of childhood cancer.

Estrogenic botanical supplements, health-related quality of life, fatigue, and hormone-related symptoms in breast cancer survivors: a HEAL study report.

BACKGROUND: It remains unclear whether estrogenic botanical supplement (EBS) use influences breast cancer survivors' health-related outcomes. METHODS: We examined the associations of EBS use with health-related quality of life (HRQOL), with fatigue, and with 15 hormone-related symptoms such as hot flashes and night sweats among 767 breast cancer survivors participating in the Health, Eating, Activity, and Lifestyle (HEAL) Study. HRQOL was measured by the Medical Outcomes Study short form-36 physical and mental component scale summary score. Fatigue was measured by the Revised-Piper Fatigue Scale score. RESULTS: Neither overall EBS use nor the number of EBS types used was associated with HRQOL, fatigue, or hormone-related symptoms. However, comparisons of those using each specific type of EBS with non-EBS users revealed the following associations. Soy supplements users were more likely to have a better physical health summary score (odds ratio [OR] = 1.66, 95% confidence interval [CI] = 1.02-2.70). Flaxseed oil users were more likely to have a better mental health summary score (OR = 1.76, 95% CI = 1.05-2.94). Ginseng users were more likely to report severe fatigue and several hormone-related symptoms (all ORs ≥ 1.7 and all 95% CIs exclude 1). Red clover users were less likely to report weight gain, night sweats, and difficulty concentrating (all OR approximately 0.4 and all 95% CIs exclude 1). Alfalfa users were less likely to experience sleep interruption (OR = 0.28, 95% CI = 0.12-0.68). Dehydroepiandrosterone users were less likely to have hot flashes (OR = 0.33, 95% CI = 0.14-0.82). CONCLUSIONS: Our findings indicate that several specific types of EBS might have important influences on a woman's various aspects of quality of life, but further verification is necessary.

Defining medical posttraumatic stress among young adult survivors in the Childhood Cancer Survivor Study.

OBJECTIVE: To examine the implications of use of differential thresholds for studying medical Posttraumatic Stress Disorder (PTSD). METHODS: Self-report data from 6,542 young adult survivors of childhood cancer and 374 of their siblings were used to create clearly differentially defined groups to compare prevalence, correlations and predictors of posttraumatic stress. RESULTS: Prevalence of posttraumatic stress in survivors compared to siblings differed by definition used, ranging from an odds ratio of 4.21 (95% CI 2.11-8.38) when posttraumatic stress was defined as meeting full symptoms plus functional impairment to 1.42 (95% CI 0.79-2.56) for partial symptoms with functional impairment. Re-experiencing symptoms did not substantially contribute to the ability to identify functional impairment and emotional distress. Although most of the variables associated with posttraumatic stress symptoms and impairment were consistent across definitions of PTSD, marital status and employment demonstrated nonproportional relationships. CONCLUSIONS: Choice of the definition used in studying posttraumatic stress after serious illness alters not only epidemiological findings, but also associations with correlates and predictors. This is important in the current debate about the criteria for PTSD in the upcoming DSMV. Further study is needed to determine if these findings are applicable to people exposed to other types of traumatic events.

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 $20,000 (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.
