Long-term sequelae in survivors of childhood leukemia with Down syndrome: A childhood cancer survivor study report.

ABSTRACT: BACKGROUND:Children with Down syndrome (DS) are at increased risk of developing acute leukemia and are more prone to acute toxicities. We studied the incidence and severity of chronic health conditions among survivors of childhood leukemia with DS compared with those without DS. METHODS:Chronic health conditions reported by questionnaire were compared between 154 pediatric leukemia survivors with DS and 581 without DS, matched by leukemia, age at diagnosis, race/ethnicity, sex, radiation location and chemotherapy exposure using Cox models to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). Subjects were selected from 7139 5-year survivors of leukemia in the Childhood Cancer Survivor Study. RESULTS:Risk of at least 1 late onset chronic health condition (grade 1-5) was similar in the DS population compared with the non-DS group (HR, 1.1; 95% CI, 0.7-1.5). Serious chronic health conditions (grade 3-5) were more common in DS survivors (HR, 1.7; 95% CI, 1.1-2.6), as were???3 chronic health conditions (grades 1-5) (HR, 1.7; 95% CI, 1.2-2.4). The 25-year cumulative incidence of any condition (grades 1-5) was 83% for DS survivors and 69% for non-DS survivors. CONCLUSION:Leukemia survivors with DS have therapy-related chronic health conditions comparable to those of similarly treated survivors without DS, with a few notable exceptions: 1) an increased risk of cataracts, hearing loss, and thyroid dysfunction compared with survivors without DS (though these are known risks in the DS population), 2) decreased risk of second cancers, and 3) increased risk of severe or multiple conditions. Practitioners should be aware of these risks during and after therapy. Cancer 2018;124:617-25. © 2017 American Cancer Society.

Project description:BackgroundChildren treated for cancer are at risk for neuromuscular dysfunction, but data are limited regarding prevalence, longitudinal patterns, and long-term impact.MethodsLongitudinal surveys from 25,583 childhood cancer survivors ≥5 years from diagnosis and 5,044 siblings from the Childhood Cancer Survivor Study were used to estimate the prevalence and cumulative incidence of neuromuscular dysfunction. Multivariable models adjusted for age, sex, race, and ethnicity estimated prevalence ratios (PR) of neuromuscular dysfunction in survivors compared with siblings, and associations with treatments and late health/socioeconomic outcomes.ResultsPrevalence of neuromuscular dysfunction was 14.7% in survivors 5 years postdiagnosis versus 1.5% in siblings [PR, 9.9; 95% confidence interval (CI), 7.9-12.4], and highest in survivors of central nervous system (CNS) tumors (PR, 27.6; 95% CI, 22.1-34.6) and sarcomas (PR, 11.5; 95% CI, 9.1-14.5). Cumulative incidence rose to 24.3% in survivors 20 years postdiagnosis (95% CI, 23.8-24.8). Spinal radiotherapy and increasing cranial radiotherapy dose were associated with increased prevalence of neuromuscular dysfunction. Platinum exposure (vs. none) was associated with neuromuscular dysfunction (PR, 1.8; 95% CI, 1.5-2.1), even after excluding survivors with CNS tumors, cranial/spinal radiotherapy, or amputation. Neuromuscular dysfunction was associated with concurrent or later obesity (PR, 1.1; 95% CI, 1.1-1.2), anxiety (PR, 2.5; 95% CI, 2.2-2.9), depression (PR, 2.1; 95% CI, 1.9-2.3), and lower likelihood of graduating college (PR, 0.92; 95% CI, 0.90-0.94) and employment (PR, 0.8; 95% CI, 0.8-0.9).ConclusionsNeuromuscular dysfunction is prevalent in childhood cancer survivors, continues to increase posttherapy, and is associated with adverse health and socioeconomic outcomes.ImpactInterventions are needed to prevent and treat neuromuscular dysfunction, especially in survivors with platinum and radiation exposure.

Project description:BackgroundSurvivors of childhood acute myeloid leukemia (AML) are vulnerable to medical late effects of treatment; however, less is known about their psychosocial outcomes. This study evaluated neurocognitive and psychosocial outcomes in long-term AML survivors treated with bone marrow transplantation (BMT) or intensive chemotherapy (IC) without BMT.MethodsAML survivors (N = 482; median age at diagnosis = 8 [range = 0-20] years; median age at evaluation = 30 [range = 18-49] years) treated with BMT (n = 183) or IC (n = 299) and sibling controls (N = 3190; median age at evaluation = 32 [range = 18-58] years) from the Childhood Cancer Survivor Study were compared on emotional distress (Brief Symptom Inventory-18), neurocognitive problems (Childhood Cancer Survivor Study Neurocognitive Questionnaire), health-related quality of life (SF-36), and social attainment. Outcomes were dichotomized (impaired vs nonimpaired) using established criteria, and relative risks (RRs) were estimated with multivariable Poisson regression, adjusted for age at evaluation and sex.ResultsAML survivors were more likely than siblings to report impairment in overall emotional (RR = 2.19, 95% confidence interval [CI] = 1.51 to 3.18), neurocognitive (RR = 2.03, 95% CI = 1.47 to 2.79), and physical quality of life (RR = 2.71, 95% CI = 1.61 to 4.56) outcomes. Survivors were at increased risk for lower education (RR = 1.15, 95% CI = 1.03 to 1.30), unemployment (RR = 1.41, 95% CI = 1.16 to 1.71), lower income (RR = 1.39, 95% CI = 1.17 to 1.65), and not being married or having a partner (RR = 1.33, 95% CI = 1.17 to 1.51). BMT-treated survivors did not differ statistically significantly from IC-treated on any outcome measure.ConclusionsAML survivors are at increased risk for psychosocial impairment compared with siblings; however, BMT does not confer additional risk for psychosocial late effects compared with treatment without BMT.

Project description:BACKGROUND:Neuroblastoma survivors may be at elevated risk for psychological impairments because of their young age at diagnosis and neurotoxic treatment, but this is not well described. METHODS:A total of 859 ?5-year survivors of neuroblastoma younger than 18 years (diagnosed in 1970-1999), who had a median age at diagnosis of 0.8 years (range: 0.0-7.3 years) and a median follow-up of 13.3 years (range: 8.0-17.9 years), were compared with 872 siblings of childhood cancer survivors who were younger than 18 years with the parent-reported Behavior Problem Index (BPI) for psychological functioning. Age- and sex-adjusted multivariate log-binomial models were used to identify factors associated with impairment in BPI domains (scores worse than the sibling 10th percentile). The impact of psychological impairment on educational outcomes was examined among survivors. RESULTS:Compared with siblings, neuroblastoma survivors had an increased prevalence of impairment in the domains of anxiety/depression (19% vs 14%; P?=?.003), headstrong behavior (19% vs 13%; P?<?.001), attention deficits (21% vs 13%; P?<?.001), peer conflict/social withdrawal (26% vs 17%; P?<?.001), and antisocial behavior (16% vs 12%; P?=?.01). Common treatment exposures (vincristine, cisplatin, and retinoic acid) were not associated with impairment. Having 2 or more chronic health conditions predicted impairment in 4 domains (P?<?.001). Specifically, pulmonary disease predicted impairment in all 5 domains (P???.004). Endocrine disease (P???.004) and peripheral neuropathy (P???.02) each predicted impairment in 3 domains. Psychological impairment was associated with special education service usage and educational attainment less than college. CONCLUSIONS:Neuroblastoma survivors are at elevated risk for psychological impairment, which is associated with special education service usage and lower adult educational attainment. Those with chronic health conditions may represent a high-risk group for targeted screening and intervention. Cancer 2018. © 2018 American Cancer Society.

Project description:BackgroundWith improved survival, more bone sarcoma survivors are approaching middle age making it crucial to investigate the late effects of their cancer and its treatment. We investigated the long-term risks of adverse outcomes among 5-year bone sarcoma survivors within the British Childhood Cancer Survivor Study.MethodsCause-specific mortality and risk of subsequent primary neoplasms (SPNs) were investigated for 664 bone sarcoma survivors. Use of health services, health and marital status, alcohol and smoking habits, and educational qualifications were investigated for survivors who completed a questionnaire.ResultsSurvivors were seven times more likely to experience all-cause mortality than expected, and there were substantial differences in risk depending on tumour type. Beyond 25 years follow-up the risk of dying from all-causes was comparable to the general population. This is in contrast to dying before 25 years where the risk was 12.7-fold that expected. Survivors were also four times more likely to develop a SPN than expected, where the excess was restricted to 5-24 years post diagnosis. Increased health-care usage and poor health status were also found. Nonetheless, for some psychosocial outcomes survivors were better off than expected.ConclusionsUp to 25 years after 5-year survival, bone sarcoma survivors are at substantial risk of death and SPNs, but this is greatly reduced thereafter. As 95% of all excess deaths before 25 years follow-up were due to recurrences and SPNs, increased monitoring of survivors could prevent mortality. Furthermore, bone and breast SPNs should be a particular concern. Since there are variations in the magnitude of excess risk depending on the specific adverse outcome under investigation and whether the survivors were initially diagnosed with osteosarcoma or Ewing sarcoma, risks need to be assessed in relation to these factors. These findings should provide useful evidence for risk stratification and updating clinical follow-up guidelines.
