<h4>Background</h4>Pulmonary complications after cancer therapy are varied. This study describes pulmonary outcomes among childhood cancer survivors and evaluates their impact on daily activities.<h4>Methods</h4>The incidence of pulmonary outcomes (asthma, chronic cough, emphysema, lung fibrosis, oxygen need, and recurrent pneumonia) reported among 5-year cancer survivors (n = 14,316) and the incidence of death due to pulmonary causes among all eligible survivors (n = 20,690) in the Childhood Ca ...[more]

Project description:Studies have found associations between cancer therapies and auditory complications, but data are limited on long-term outcomes and risks associated with multiple exposures.The Childhood Cancer Survivor Study is a retrospective cohort investigating health outcomes of long-term survivors (5+ years) diagnosed and treated between 1970 and 1986 compared to a randomly selected sibling cohort. Questionnaires were completed by 14,358 survivors of childhood cancer and 4,023 sibling controls. Analysis determined the first occurrence of four auditory conditions in two time periods: diagnosis to 5 years post-diagnosis, and ? 5 years post-diagnosis. Multivariable analyses determined the relative risks (RR) and 95% confidence interval (CI) of auditory conditions by treatment exposure.Five or more years from cancer diagnosis, survivors were at increased risk of problems hearing sounds (RR = 2.3; 95% CI: 1.8-2.8), tinnitus (RR = 1.7; 95% CI: 1.4-2.1), hearing loss requiring an aid (RR = 4.4; 95% CI: 2.8-6.9), and hearing loss in 1 or both ears not corrected by a hearing aid (RR = 5.2; 95% CI: 2.8-9.5), when compared to siblings. Temporal lobe and posterior fossa radiation was associated with these outcomes in a dose-dependent fashion. Exposure to platinum compounds was associated with an increased risk of problems hearing sounds (RR = 2.1; 95% CI: 1.3-3.2), tinnitus (RR = 2.8; 95% CI: 1.9-4.2), and hearing loss requiring an aid (RR = 4.1; 95% CI: 2.5-6.7).Childhood cancer survivors are at risk of developing auditory complications. Radiation and platinum compounds are determinants of this risk. Follow-up is needed to evaluate the impact of auditory conditions on quality of life.

Project description:Childhood cancer survivors have an increased risk of secondary sarcomas. To better identify those at risk, the relationship between therapeutic dose of chemotherapy and radiation and secondary sarcoma should be quantified.We conducted a nested case-control study of secondary sarcomas (105 cases, 422 matched controls) in a cohort of 14,372 childhood cancer survivors. Radiation dose at the second malignant neoplasm (SMN) site and use of chemotherapy were estimated from detailed review of medical records. Odds ratios (ORs) and 95% confidence intervals were estimated by conditional logistic regression. Excess odds ratio (EOR) was modeled as a function of radiation dose, chemotherapy, and host factors.Sarcomas occurred a median of 11.8 years (range, 5.3-31.3 years) from original diagnosis. Any exposure to radiation was associated with increased risk of secondary sarcoma (OR = 4.1, 95% CI = 1.8-9.5). A dose-response relation was observed, with elevated risks at doses between 10 and 29.9 Gy (OR = 15.6, 95% CI = 4.5-53.9), 30-49.9 Gy (OR = 16.0, 95% CI 3.8-67.8) and >50 Gy (OR = 114.1, 95% CI 13.5-964.8). Anthracycline exposure was associated with sarcoma risk (OR = 3.5, 95% CI = 1.6-7.7) adjusting for radiation dose, other chemotherapy, and primary cancer. Adjusting for treatment, survivors with a first diagnosis of Hodgkin lymphoma (OR = 10.7, 95% CI = 3.1-37.4) or primary sarcoma (OR = 8.4, 95% CI = 3.2-22.3) were more likely to develop a sarcoma.Of the risk factors evaluated, radiation exposure was the most important for secondary sarcoma development in childhood cancer survivors; anthracycline chemotherapy exposure was also associated with increased risk.

Project description:Female survivors of childhood cancer treated with abdominal radiotherapy who manage to conceive are at risk of delivering premature and low-birthweight offspring, but little is known about whether abdominal radiotherapy may also be associated with additional complications during pregnancy and labor. We investigated the risk of developing pregnancy and labor complications among female survivors of childhood cancer in the British Childhood Cancer Survivor Study (BCCSS).Pregnancy and labor complications were identified by linking the BCCSS cohort (n?=?17 980) to the Hospital Episode Statistics (HES) for England. Relative risks (RRs) of pregnancy and labor complications were calculated by site of radiotherapy treatment (none/abdominal/cranial/other) and other cancer-related factors using log-binomial regression. All statistical tests were two-sided.A total of 2783 singleton pregnancies among 1712 female survivors of childhood cancer were identified in HES. Wilms tumor survivors treated with abdominal radiotherapy were at threefold risk of hypertension complicating pregnancy (relative risk = 3.29, 95% confidence interval [CI] = 2.29 to 4.71), while all survivors treated with abdominal radiotherapy were at risk of gestational diabetes mellitus (RR?=?3.35, 95% CI?=?1.41 to 7.93) and anemia complicating pregnancy (RR?=?2.10, 95% CI?=?1.27 to 3.46) compared with survivors treated without radiotherapy. Survivors treated without radiotherapy had similar risks of pregnancy and labor complications as the general population, except survivors were more likely to opt for an elective cesarean section (RR?=?1.39, 95% CI?=?1.16 to 1.70).Treatment with abdominal radiotherapy increases the risk of developing hypertension complicating pregnancy in Wilms tumor survivors, and diabetes mellitus and anemia complicating pregnancy in all survivors. These patients may require extra vigilance during pregnancy.

Project description:BACKGROUND:The objective of the current study was to characterize and identify factors associated with perceptions of risk of infertility among adult male survivors of childhood cancer. METHODS:A total of 1233 adult male survivors from the Childhood Cancer Survivor Study who were without a history of disease recurrence or subsequent malignancy reported their perceptions of their risk of infertility compared with men never diagnosed with cancer. Survivors were a median age of 37.8 years (range, 22.0-58.7 years) and were 28.4 years from their diagnosis (range, 21.4-39.2 years). Multivariable logistic regression evaluated factors associated with perceptions of risk. RESULTS:Overall, 35.9% of the survivors (443 of 1233 survivors) reported perceptions of their risk of infertility that were discordant with their actual risk based on previous cancer treatment exposures. Discordant perceptions were equally common among men exposed to gonadotoxic therapies (36.3%; 311 of 857 men) and those with no history of gonadotoxic exposure (35.1%; 132 of 376 men). Survivors who fathered children (odds ratio [OR], 4.14; 95% confidence interval [95% CI], 2.74-6.24), had no survivor-focused health care (OR, 3.07; 95% CI, 1.57-5.99), were nonwhite (OR, 2.28; 95% CI, 1.10-4.75), and were of lower income were more likely to report no increased risk of infertility after gonadotoxic treatment. Perceptions of increased risk of infertility among men with no history of gonadotoxic treatment were predicted by never having fathered a child (OR, 1.88; 95% CI, 1.17-3.03), recent participation in survivor-focused health care (OR, 2.11; 95% CI, 1.01-4.42), and higher educational achievement. CONCLUSIONS:Many male survivors of childhood cancer are unaware of how their cancer treatments could impact their reproductive health, underscoring the need for all patients to receive education regarding their risk of infertility throughout the continuum of cancer care.

Project description:Adult childhood cancer survivors report high levels of unemployment, although it is unknown whether this is because of health or employability limitations.We examined 2 employment outcomes from 2003 in the Childhood Cancer Survivor Study (CCSS): (1) health-related unemployment and (2) unemployed but seeking work. We compared survivors with a nearest-age CCSS sibling cohort and examined demographic and treatment-related risk groups for each outcome.We studied 6339 survivors and 1967 siblings ?25 years of age excluding those unemployed by choice. Multivariable generalized linear models evaluated whether survivors were more likely to be unemployed than siblings and whether certain survivors were at a higher risk for unemployment.Survivors (10.4%) reported health-related unemployment more often than siblings (1.8%; Relative Risk [RR], 6.07; 95% Confidence Interval [CI], 4.32-8.53). Survivors (5.7%) were more likely to report being unemployed but seeking work than siblings (2.7%; RR, 1.90; 95% CI, 1.43-2.54). Health-related unemployment was more common in female survivors than males (Odds Ratio [OR], 1.73; 95% CI, 1.43-2.08). Cranial radiotherapy doses ?25 Gy were associated with higher odds of unemployment (health-related: OR, 3.47; 95% CI, 2.54-4.74; seeking work: OR, 1.77; 95% CI, 1.15-2.71). Unemployed survivors reported higher levels of poor physical functioning than employed survivors, and had lower education and income and were more likely to be publicly insured than unemployed siblings.Childhood cancer survivors have higher levels of unemployment because of health or being between jobs. High-risk survivors may need vocational assistance.

Project description:BACKGROUND:Childhood cancer survivors are at risk for adverse psychological outcomes. Whether exercise can attenuate this risk is unknown. METHODS:In total, 6199 participants in the Childhood Cancer Survivor Study (median age, 34.3 years [range, 22.0-54.0 years]; median age at diagnosis, 10.0 years [range, 0-21.0 years]) completed a questionnaire assessing vigorous exercise and medical/psychological conditions. Outcomes were evaluated a median of 7.8 years (range, 0.1-10.0 years) later and were defined as: symptom level above the 90th percentile of population norms for depression, anxiety, or somatization on the Brief Symptom Inventory-18; cancer-related pain; cognitive impairment using a validated self-report neurocognitive questionnaire; or poor health-related quality of life. Log-binomial regression estimated associations between exercise (metabolic equivalent [MET]-hours per week-1 ) and outcomes adjusting for cancer diagnosis, treatment, demographics, and baseline conditions. RESULTS:The prevalence of depression at follow-up was 11.4% (95% CI, 10.6%-12.3%), anxiety 7.4% (95% CI, 6.7%-8.2%) and somatization 13.9% (95% CI, 13.0%-14.9%). Vigorous exercise was associated with lower prevalence of depression and somatization. The adjusted prevalence ratio for depression was 0.87 (95% CI, 0.72-1.05) for 3 to 6 MET hours per week-1 , 0.76 (95% CI, 0.62-0.94) for 9 to 12 MET-hours per week-1 , and 0.74 (95% CI, 0.58-0.95) for 15 to 21 MET-hours per week-1 . Compared with 0 MET hours per week-1 , 15 to 21 MET-hours per week-1 were associated with an adjusted prevalence ratio of 0.79 (95% CI, 0.62-1.00) for somatization. Vigorous exercise also was associated with less impairment in the physical functioning, general health and vitality (Ptrend < .001), emotional role limitations (Ptrend = .02), and mental health (Ptrend = .02) domains as well as higher cognitive function in the domains of task completion, organization, and working memory (P < .05 for all), but not in the domain of cancer pain. CONCLUSIONS:Vigorous exercise is associated with less psychological burden and cognitive impairment in childhood cancer survivors.

Project description:BackgroundThe prevalence and associated psychosocial morbidity of late-onset anorectal disease after surgery and radiotherapy for the treatment of childhood cancer are not known.MethodsA total of 25,530 survivors diagnosed between 1970 and 1999 (median age at cancer diagnosis, 6.1 years; age at survey, 30.2 years) and 5036 siblings were evaluated for late-onset anorectal disease, which was defined as a self-reported fistula-in-ano, self-reported anorectal stricture, or pathology- or medical record-confirmed anorectal subsequent malignant neoplasm (SMN) 5 or more years after the primary cancer diagnosis. Piecewise exponential models compared the survivors and siblings and examined associations between cancer treatments and late-onset anorectal disease. Multiple logistic regression with generalized estimating equations was used to evaluate associations between late-onset anorectal disease and emotional distress, as defined by the Brief Symptom Inventory 18 (BSI-18), and health-related quality of life, as defined by the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36).ResultsBy 45 years after the diagnosis, 394 survivors (fistula, n = 291; stricture, n = 116; anorectal SMN, n = 26) and 84 siblings (fistula, n = 73; stricture, n = 23; anorectal neoplasm, n = 1) had developed late-onset anorectal disease (adjusted rate ratio [RR] for survivors vs siblings, 1.2; 95% confidence interval [CI], 1.0-1.5). Among survivors, pelvic radiotherapy with ≥30 Gy within 5 years of the cancer diagnosis was associated with late-onset anorectal disease (adjusted RR for 30-49.9 Gy vs none, 1.6; 95% CI, 1.1-2.3; adjusted RR for ≥50 Gy vs none, 5.4; 95% CI, 3.1-9.2). Late-onset anorectal disease was associated with psychosocial impairment in all BSI-18 and SF-36 domains.ConclusionsLate-onset anorectal disease was more common among childhood cancer survivors who received higher doses of pelvic radiotherapy and was associated with substantial psychosocial morbidity.

Project description:BackgroundPrior studies have identified that survivors of childhood acute lymphoblastic leukemia (ALL) report poor health status. It is unknown how risk-stratified therapy impacts the health status of ALL survivors.MethodsWe estimated and compared the prevalence of self-reported poor health status among adult (≥18 years) survivors of childhood ALL diagnosed at age <21 years from 1970 to 1999 and sibling controls, excluding proxy reports. Therapy combinations defined treatment groups representative of 1970s therapy (70s), standard- and high-risk 1980s and 1990s therapy (80sSR, 80sHR, 90sSR, 90sHR), and relapse/bone marrow transplant (R/BMT). Log-binomial models, adjusted for clinical and demographic factors, compared outcomes between groups using prevalence ratios (PR) with 95% confidence intervals (CI).ResultsAmong 5,119 survivors and 4,693 siblings, survivors were more likely to report poor health status in each domain including poor general health (13.5% vs. 7.4%; PR = 1.92; 95% CI, 1.69-2.19). Compared with 70s, 90sSR and 90sHR were less likely to report poor general health (90sSR: PR = 0.75; 95% CI, 0.57-0.98; 90sHR: PR = 0.58; 95% CI, 0.39-0.87), functional impairment (90sSR: PR = 0.56; 95% CI, 0.42-0.76; 90sHR: PR = 0.63; 95% CI, 0.42-0.95), and activity limitations (90sSR: 0.61; 95% CI, 0.45-0.83; 90sHR: PR = 0.59; 95% CI, 0.38-0.91). An added adjustment for chronic conditions in multivariable models partially attenuated 90sSR risk estimates.ConclusionsRisk-stratified ALL therapy has succeeded in reducing risk for poor general health, functional impairment, and activity limitations among more recent survivors of standard- and high-risk therapy.ImpactFuture research into the relationship between risk-stratified therapy, health status, and late health outcomes may provide new opportunities to further improve late morbidity among survivors.

Project description:BACKGROUND:Survivors of childhood cancer are at significant risk for serious chronic health conditions and subsequent cancers because of their prior treatment exposures. However, little is known about survivors' perceptions of their future health risks. METHODS:This study examined self-reported levels of concern about future health and subsequent cancer in 15,620 adult survivors of childhood cancer (median age, 26 years; median time since diagnosis, 17 years) and 3991 siblings in the Childhood Cancer Survivor Study. The prevalence of concerns was compared between survivors and siblings, and the impact of participant characteristics and treatment exposures on concerns was examined with multivariable modified Poisson regression to estimate relative risks (RRs) and 95% confidence intervals (CIs). RESULTS:A substantial proportion of survivors were not concerned about their future health (31%) or developing cancer (40%). The prevalence of concern in survivors was modestly higher (RR for future health, 1.12; 95% CI, 1.09-1.15) or similar (RR for subsequent cancer, 1.02; 95% CI, 0.99-1.05) in comparison with siblings. Survivors exposed to high doses of radiation (?20 Gy) were more likely to report concern (RR for future health, 1.13; 95% CI, 1.09-1.16; RR for subsequent cancer, 1.14; 95% CI, 1.10-1.18), but 35% of these high-risk survivors were not concerned about developing cancer, and 24% were not concerned about their future health. CONCLUSIONS:A substantial subgroup of survivors were unconcerned about their future health and subsequent cancer risks, even after exposure to treatments associated with increased risk. These survivors may be less likely to engage in beneficial screening and risk-reduction activities. Cancer 2018. © 2018 American Cancer Society.

Project description:The current study was performed to examine associations between childhood cancer therapies, chronic health conditions, and symptoms of emotional distress in adult survivors of childhood cancer.Participants included 5021 adult survivors of childhood cancer (mean age, 32.0 years [standard deviation, 7.6 years] with a time since diagnosis of 23.2 years [standard deviation, 4.5 years]) who completed measures assessing symptoms of anxiety, depression, and posttraumatic stress. Cardiac, pulmonary, and endocrine conditions were graded using the National Cancer Institute Common Terminology Criteria for Adverse Events (version 4.03; grades 1-4). Structural equation modeling was used to examine hypothesized pathways between cancer treatment exposures, chronic health conditions, and symptoms of emotional distress. Multivariable models were used to estimate relative risks (RRs) for associations between chronic health conditions and distress.Survivors with cardiovascular, endocrine, or pulmonary conditions were found to have a significantly higher prevalence of emotional distress symptoms. In path analyses and multivariable models, significant effects were observed between endocrine (??=?.12 [P?=?.002] and RR, 1.3 [95% confidence interval (95% CI), 1.1-1.6]) and pulmonary (??=?.13 [P<.001] and RR, 1.4 [95% CI, 1.1-1.7]) conditions and depression, and between cardiac (??=?.13 [P?=?.001] and RR, 1.5 [95% CI, 1.2-1.8]) and pulmonary (??=?.15 [P<.001] and RR, 1.6 [95% CI, 1.3-2.0]) conditions and anxiety. All treatment-related chronic health conditions were found to be associated with posttraumatic stress symptoms (cardiac: ??=?.09 [P?=?.004] and RR, 1.3 [95% CI, 1.2-1.5]; endocrine: ??=?.12 [P<.001] and RR, 1.3 [95% CI, 1.2-1.5]; and pulmonary: ??=?.13 [P<.001] and RR, 1.4 [95% CI, 1.2-1.6]).Chronic health conditions resulting from childhood cancer therapies contribute to emotional distress in adult survivors. Targeted mental health screening efforts in this at-risk population appear warranted. Therapeutic approaches should consider the complex interplay between chronic health conditions and symptoms of emotional distress. Cancer 2017;123:521-528. © 2016 American Cancer Society.
