Background: Survivors of childhood cancer report poor health-related quality of life (HRQOL). Modifiable lifestyle factors such as nutrition and physical activity represent opportunities for interventions to improve HRQOL., Methods: The authors examined the association between modifiable lifestyle factors and HRQOL among 2480 adult survivors of childhood cancer in the St. Jude Lifetime Cohort Study. Dietary intake, physical activity, cigarette smoking, and alcohol consumption were assessed through questionnaires. Weight and height were measured in the clinic. HRQOL was evaluated using the Medical Outcome Study 36-Item Short Form Survey. The physical component summary (PCS), mental component summary (MCS), and 8 domain scores of HRQOL were calculated. Multivariable linear regression models were used to estimate regression coefficients (β) associated with HRQOL differences., Results: Being physically active (PCS β = 3.10; and MCS β = 1.48) was associated with higher HRQOL whereas current cigarette smoking (PCS β = -2.30; and MCS β = -6.49) and obesity (body mass index ≥30 kg/m 2 ) (PCS β = -3.29; and MCS β = -1.61) were associated with lower HRQOL in both the physical and mental domains. Better diet (Healthy Eating Index-2015) was associated with higher physical HRQOL (PCS β = 1.79). Moderate alcohol consumption was associated with higher physical (PCS β = 1.14) but lower mental (MCS β = -1.13) HRQOL (all P <.05). Adherence to multiple healthy lifestyle factors demonstrated a linear trend with high scores in both physical and mental HRQOL (highest vs lowest adherence: PCS β = 7.60; and MCS β = 5.76 [P for trend, <.0001])., Conclusions: The association between healthy lifestyle factors and HRQOL is cumulative, underscoring the importance of promoting multiple healthy lifestyles to enhance HRQOL in long-term survivors of childhood cancer., (© 2018 American Cancer Society.)

Purpose: To estimate the prevalence of and risk factors for growth hormone deficiency (GHD), luteinizing hormone/follicle-stimulating hormone deficiencies (LH/FSHD), thyroid-stimulatin hormone deficiency (TSHD), and adrenocorticotropic hormone deficiency (ACTHD) after cranial radiotherapy (CRT) in childhood cancer survivors (CCS) and assess the impact of untreated deficiencies., Patients and Methods: Retrospective study in an established cohort of CCS with 748 participants treated with CRT (394 men; mean age, 34.2 years [range, 19.4 to 59.6 years] observed for a mean of 27.3 years [range, 10.8 to 47.7 years]). Multivariable logistic regression was used to study associations between demographic and treatment-related risk factors and pituitary deficiencies, as well as associations between untreated deficiencies and cardiovascular health, bone mineral density (BMD), and physical fitness., Results: The estimated point prevalence was 46.5% for GHD, 10.8% for LH/FSHD, 7.5% for TSHD, and 4% for ACTHD, and the cumulative incidence increased with follow-up. GHD and LH/FSHD were not treated in 99.7% and 78.5% of affected individuals, respectively. Male sex and obesity were significantly associated with LH/FSHD; white race was significant associated with LH/FSHD and TSHD. Compared with CRT doses less than 22 Gy, doses of 22 to 29.9 Gy were significantly associated with GHD; doses ≥ 22 Gy were associated with LH/FSHD; and doses ≥ 30 Gy were associated with TSHD and ACTHD. Untreated GHD was significantly associated with decreased muscle mass and exercise tolerance; untreated LH/FSHD was associated with hypertension, dyslipidemia, low BMD, and slow walking; and both deficits, independently, were associated with with abdominal obesity, low energy expenditure, and muscle weakness., Conclusion: Anterior pituitary deficits are common after CRT. Continued development over time is noted for GHD and LH/FSHD with possible associations between nontreatment of these conditions and poor health outcomes., (© 2015 by American Society of Clinical Oncology.)

Background: With increasing numbers of childhood cancer survivors, direct sequelae of cancer therapy and psychosocial outcomes are becoming more important. The authors described psychosocial outcomes (education, employment, health insurance, and marriage) for survivors of pediatric lower extremity bone tumors., Methods: The long-term follow-up study of the Childhood Cancer Survivor Study is a multiinstitutional cohort study comprising 14,054 individuals who have survived for 5 or more years after treatment for cancer diagnosed during childhood or adolescence. Baseline demographic and medical information were obtained. Six hundred ninety-four survivors had osteosarcoma or Ewing sarcoma of the lower extremity or pelvis and were classified by amputation status and by age at diagnosis. The median age at diagnosis was 14 years old with a median of 16 years of follow up since diagnosis. Demographic characteristics were used to analyze the rates of psychosocial outcomes., Results: Amputation status and age at diagnosis did not significantly influence any of the measured psychosocial outcomes. Education was a significant positive predictor of employment, having health insurance, and being currently in their first marriage. Male gender predicted ever being employed and female gender predicted having health insurance and marriage. When compared with siblings, amputees had significant deficits in education, employment, and health insurance., Conclusions: Overall, no differences between amputees and nonamputees were found. However, gender and education play a prominent role. When compared with siblings, amputees in this cohort may benefit from additional supports., (Copyright 2003 American Cancer Society.DOI 10.1002/cncr.11363)
