10055 Background: Though hearing loss is a significant late effect among childhood cancer survivors, recent guidelines note insufficient evidence to quantify natural history or risk associated with specific exposures. We examined the long-term incidence and predictors of hearing loss requiring hearing amplification devices (HAD) using population-based healthcare data. Methods: In Ontario, Canada, HAD costs are subsidized by the provincial Assistive Devices Program (ADP). Ontario children age <18 years at cancer diagnosis between 1987-2016 were identified using a pediatric cancer registry and linked to ADP claims. The cumulative incidence of HAD use was compared between cases and matched controls. Patient, disease, and treatment predictors of HAD were examined. Results: We identified 11,842 cases and 59,210 matched controls. Cases were at higher risk of HAD [hazard ratio (HR) 12.8, 95% confidence interval (95CI) 9.8-16.7; p<0.001]. The cumulative incidence of HAD among survivors was 2.1% (95CI 1.7-2.5%) at 20-years and 6.4% (95CI 2.8-12.1%) at 30-years. 30-year incidence was highest in survivors of neuroblastoma (10.7%, 95CI 3.8-21.7%) and hepatoblastoma (16.2%, 95CI 8.6-26.0%). Predictors of HAD in multivariable analyses included age 0-4 years at diagnosis (vs. 5-9 years, HR 2.2, 95CI 1.4-3.3; p<0.001). Relative to no cisplatin exposure, patients receiving 1-200mg/m2 were not at greater risk, unlike those receiving higher cumulative doses (Table). Relative to no radiation, those receiving ≤32Gy were at no higher risk, unlike while those receiving >32Gy. Carboplatin exposure was not associated with HAD. Conclusions: Childhood cancer survivors are at elevated risk of requiring HAD which continues to rise between 20 and 30 years from diagnosis. Thresholds of cisplatin and radiation exposure exist above which risk substantially increases. Prolonged monitoring and trials of otoprotective agents are warranted in high-risk populations.

PURPOSE Hearing loss is a significant late effect among childhood cancer survivors. Recent guidelines note insufficient evidence to quantify its natural history or risk associated with specific exposures. We examined the long-term incidence and predictors of hearing loss requiring hearing amplification devices (HADs) using population-based health care data. METHODS In Ontario, Canada, HAD costs are subsidized by the Assistive Devices Program (ADP). Ontario children < 18 years of age at cancer diagnosis between 1987 and 2016 were identified and linked to ADP claims. Cumulative HAD incidence was compared between cases and matched controls. Patient, disease, and treatment predictors of HAD were examined. RESULTS We identified 11,842 cases and 59,210 controls. Cases were at higher risk for HAD (hazard ratio [HR], 12.8; 95% CI, 9.8 to 16.7; P < .001). The cumulative incidence of HAD among survivors was 2.1% (95% CI, 1.7% to 2.5%) at 20 years and 6.4% (95% CI, 2.8% to 12.1%) at 30 years post-diagnosis. The 30-year incidence was highest in neuroblastoma (10.7%; 95% CI, 3.8% to 21.7%) and hepatoblastoma (16.2%; 95% CI, 8.6% to 26.0%) survivors. Predictors of HAD in multivariable analyses included age 0-4 years at diagnosis ( v 5-9 years; HR, 2.2; 95% CI, 1.4-3.3; P < .001). Relative to no cisplatin exposure, patients receiving < 200 mg/m2 were not at greater risk, unlike those receiving higher cumulative doses. Relative to no cranial or facial radiation, those who had received ≤ 32.00 Gy were at no higher risk, unlike those who had received > 32.00 Gy. Carboplatin exposure was not associated with HAD. CONCLUSION Childhood cancer survivors are at elevated risk for requiring HAD, which continues to increase between 20 and 30 years after diagnosis. Thresholds of cisplatin and radiation exposure exist, above which risk substantially increases. Prolonged monitoring and trials of otoprotective agents are warranted in high-risk populations.

CRA9513 Background: The risk of breast cancer (BC) by age 50 among women treated for childhood cancer with chest radiation therapy (RT) and how this risk compares with that of BRCA1 and BRCA2 (BRCA1/2) mutation carriers is unknown. Methods: We evaluated the risk of BC in a cohort of 1268 female 5-yr childhood cancer survivors treated with chest RT and estimated the cumulative incidence of BC non-parametrically treating death as a competing risk. The cumulative incidence of BC in BRCA1/2 mutation carriers was estimated with the kin-cohort method using data from 4570 female first-degree relatives of women diagnosed with unilateral BC (probands) participating in the WECARE Study. Absolute Excess Risks (AERs) were estimated using population-based data from the SEER program. Results: With a median follow-up of 26 yrs (range 5-39) for the CCSS cohort, 175 women were diagnosed with BC at a median age of 38 yrs (range 24-53) and a median latency of 23 yrs (range 7-38); the overall cumulative incidence of BC by age 50 was 24% (95% confidence interval [CI] 20-28%) and among Hodgkin lymphoma survivors was 30% (95% CI 25-35%). In comparison, among first-degree relatives of WECARE Study probands 324 were diagnosed with BC (median age at diagnosis, 55 yrs (range 26-90)). The estimated cumulative incidence by age 50 was 31% (95% CI 16-47%) and 10% (95% CI 2-23%) in carriers of BRCA1 and BRCA2 mutations, respectively. The population cumulative incidence of BC is 4% by age 50. Among the childhood cancer survivors, AERs for BCs diagnosed per 10,000 person-years of observation were respectively 34 (95% CI 18-52), 27 (95% CI 11-45), and 95 (95% CI 78-112) among women treated with 10-19 Gy (23%), 20-29 Gy (17%), and 30+ Gy (56%) of chest RT. Conclusions: Women treated for childhood cancer with chest RT have a substantial risk of BC comparable to BRCA1/2 mutation carriers and considerably greater than that of the general population. Women treated with 10-19 Gy RT had an increased excess risk warranting consideration of breast cancer surveillance strategies similar to the current recommendations for women treated with > 20 Gy.

10014 Background: Childhood cancer survivors face increased risk for DM, a polygenic trait also attributable to cancer treatment exposures, particularly abdominal radiation. We aimed to characterize the role of genetic and treatment risk factors for DM among two large cohorts of childhood cancer survivors. Methods: We performed a nested case-control genome-wide association study for DM managed with oral medications in the original CCSS cohort (diagnosed 1970-1986). Logistic regression was conducted in the total sample (N = 5083) and stratified by 1) European ancestry (EA) and 2) abdominal radiation. Replication of suggestive variants (P < 1×10-7) using Fisher’s exact test was performed in independent cohorts: i) CCSS expansion diagnosed 1987-1999 (N = 2588) and ii) SJLIFE diagnosed 1962-2012 (N = 2182). To evaluate the effect of cancer treatment on the background genetic predisposition to DM, we estimated standardized effect sizes (Z’) among EA survivors in each abdominal radiation group for 398 index variants from the largest population-based EA DM study. Radiation group Z’ estimates were compared using linear regression. Results: In the original CCSS cohort we identified nine variants associated with DM and provide further support for four linked variants in the ERCC6L2 locus. Among all survivors, the rs55849673-A allele was associated with increased odds for DM among survivors in the original CCSS cohort (minor allele frequency [MAF]-cases = 0.055; MAF-controls = 0.024; adjusted odds ratio [aOR] = 2.9, 95% CI: 2.0-4.2, P = 3.7×10-8). Allele frequencies were consistent in the CCSS expansion (MAF-cases = 0.075; MAF-controls = 0.028; P = 0.07) and SJLIFE (MAF-cases = 0.036; MAF-controls = 0.027; P = 0.5). Additionally, rs55849673-A estimates were consistent among EA survivors and stronger among survivors not treated with abdominal radiation (MAF-cases = 0.052; MAF-controls = 0.021; aOR = 3.6, P = 1.6×10-6). Notably, in the CCSS expansion all rs55849673-A EA carriers who developed DM did not receive abdominal radiation (MAF-cases = 0.1; MAF-controls = 0.026; P = 0.04). More broadly, the Z’ of population-based DM index variants were 78% lower in survivors treated with abdominal radiation than survivors not treated with abdominal radiation (beta = 0.22; P = 0.01), indicating the background genetic risk for DM may be altered by treatment. Conclusions: We provide evidence for a novel locus of DM in childhood cancer survivors. This locus is a regulatory region associated with expression of ERCC6L2, a gene implicated in an East Asian population-based DM study. Taken together, our findings support the overwhelming effect of abdominal radiation on DM risk in childhood cancer survivors, relative to other risk factors, and provide insight on a genetic locus that may be useful for DM risk prediction in the context of cancer treatment.

10546 Background: Childhood cancer survivors are at risk for neuromuscular dysfunction. We estimated the prevalence and cumulative incidence of neuromuscular dysfunction in a cohort of childhood cancer survivors and examined associations with treatment exposures and health/socioeconomic outcomes. Methods: CCSS participants ≥5 years from cancer diagnosed between 1970-1999 (n = 25,583, 46.5% female, median [range] age 54.4 [15.1-57.6] years) and siblings (n = 5,044, 52.3% female, median [range] age 54.1 [32.5-57.0] years) were included. Neuromuscular dysfunction was identified by self-report of 1) motor dysfunction: impaired balance, tremor, or extremity weakness; 2) sensory dysfunction: impaired touch sensation. Multivariable analyses examined predictors of dysfunction by diagnosis. Results: Cumulative incidence of neuromuscular dysfunction was elevated at 20 years from diagnosis in survivors (24.3%, 95% CI 23.8-24.8; motor 18.2%, sensory 13.5%) versus siblings (8.9%, 95% CI 8.1-9.7). In survivors five years from diagnosis, motor dysfunction was associated with exposure to cytarabine (OR = 1.39, 95% CI 1.10-1.77) and spinal radiation (OR = 2.11, 95% CI 1.31-3.41) in acute lymphoblastic leukemia/non-hodgkin lymphoma (ALL/NHL), vinca alkaloids (OR 1.29, 95% CI 1.03-1.60) and brain radiation (OR = 1.58, 95% CI 1.35-1.85) in central nervous system tumors, and cytarabine (OR = 3.73, 95% CI 1.62-8.57) and non-brain/spine radiation (OR = 1.84, 95% CI 1.42-2.40) in bone/soft tissue tumors. Sensory dysfunction was associated with exposure to vinca alkaloids (OR = 3.45, 95% CI 1.06-11.22) in ALL/NHL, and platinum agents (OR = 1.31, 95% CI 1.03-1.67) and spinal radiation (OR = 3.71, 95% CI 1.24-11.11) in bone/soft tissue tumors. Survivors with neuromuscular dysfunction were at increased risk for adverse health/socioeconomic outcomes (Table). Conclusions: Neuromuscular dysfunction is a prevalent morbidity in childhood cancer survivors, associated with specific therapies within a particular diagnosis. Interventions are needed to identify and improve neuromuscular dysfunction given its association with adverse health/socioeconomic outcomes. [Table: see text]

ObjectiveIn this report, we determine the cumulative incidence of symptomatic cardiac ischaemia and its risk factors among European 5-year childhood cancer survivors (CCS) participating in the PanCareSurFup study.MethodsEight data providers (France, Hungary, Italy (two cohorts), the Netherlands, Slovenia, Switzerland and the UK) participating in PanCareSurFup ascertained and validated symptomatic cardiac events among their 36 205 eligible CCS. Data on symptomatic cardiac ischaemia were graded according to the Criteria for Adverse Events V.3.0 (grade 3–5). We calculated cumulative incidences, both overall and for different subgroups based on treatment and malignancy, and used multivariable Cox regression to analyse risk factors.ResultsOverall, 302 out of the 36 205 CCS developed symptomatic cardiac ischaemia during follow-up (median follow-up time after primary cancer diagnosis: 23.0 years). The cumulative incidence by age 60 was 5.4% (95% CI 4.6% to 6.2%). Men (7.1% (95% CI 5.8 to 8.4)) had higher rates than women (3.4% (95% CI 2.4 to 4.4)) (p<0.0001). Of importance is that a significant number of patients (41/302) were affected as teens or young adults (14–30 years). Treatment with radiotherapy/chemotherapy conferred twofold risk (95% CI 1.5 to 3.0) and cases in these patients appeared earlier than in CCS without treatment/surgery only (15% vs 3% prior to age 30 years, respectively (p=0.04)).ConclusionsIn this very large European childhood cancer cohort, we found that by age 60 years, 1 in 18 CCS will develop a severe, life-threatening or fatal cardiac ischaemia, especially in lymphoma survivors and CCS treated with radiotherapy and chemotherapy increases the risk significantly.

Background.Population-based studies are needed to estimate the prevalence of underweight or overweight/obese childhood cancer survivors.Procedure.Adult survivors (diagnosed ≤20 years) were identified from the linked Utah Cancer Registry and Utah Population Database. We included survivors currently aged ≥20 years and ≥5 years from diagnosis(N=1060), and a comparison cohort selected on birth year and sex(N=5410). BMI was calculated from driver license data available from 2000 to 2010. Multivariable generalized linear regression models were used to calculate prevalence relative risks (RR) and 95% confidence intervals (95% CI) of BMI outcomes for survivors and the comparison cohort.Results.Average time since diagnosis was 18.5 years(SD=7.8), and mean age at BMI for both groups was 30.5 (survivorsSD=7.7, comparisonSD=8.0). Considering all diagnoses, survivors were not at higher risk for being underweight or overweight/obese than the comparison. Male central nervous system tumor survivors were overweight (RR=1.12, 95% CI 1.01–1.23) more often than the comparison. Female survivors, who were diagnosed at age 10 and under, had a 10% higher risk of being obese than survivors diagnosed at ages 16–20(P<0.05).Conclusion.While certain groups of childhood cancer survivors are at risk for being overweight/obese, in general they do not differ from population estimates.

Background: Among childhood cancer survivors, cranial radiation therapy (CRT) increases risk of self-reported first-stroke; there are no published estimates of recurrent stroke. Objective: To assess rates and predictors of first and recurrent stroke in childhood cancer survivors treated with CRT. Methods: In a retrospective cohort study of all children who received CRT at one institution,1980-2009, we performed chart abstraction (n=321) and phone interviews (n=101) to measure first and recurrent stroke; we confirmed stroke through imaging review. Incidence of first-stroke was calculated as the number of first strokes per person-years of observation after radiation. We used survival analysis techniques to determine the cumulative incidence of first stroke after radiation, and recurrent stroke after first stroke; we used Cox proportional hazards models to examine potential predictors of first stroke. Results: Median age of children at the time of CRT treatment was 8 years (IQR 4-13 years). A total of 17 first-strokes (12 ischemic, 2 hemorrhagic, 3 unknown sub-type) were identified at a median age of 25 years (IQR 17-34 years): 6 from chart review, 8 from interview, 3 from both. Imaging was available in 12 cases and consistent with stroke in all. The overall rate of first-stroke was 594 (95% CI 346 - 949) per 100,000 person-years. The risk of stroke persists for decades after treatment (see Figure ). Males had a 4-fold hazard of first stroke compared to females (95% CI 1.1 - 14; P =0.034). Race and treatment with chemotherapy did not affect the stroke risk; dose effect of CRT could not be assessed due to a narrow dose range in our cohort. There were 5 recurrent strokes (2 ischemic, 2 hemorrhagic, 1 unknown) at a median of 6 months after first stroke (range 5.6 months to 8.9 years); brain imaging was available in 4 cases and consistent with stroke in all. The cumulative incidence of recurrent stroke was 21% (95% CI 7.5-53) at 1 year post first-stroke, 29% (95% CI 12-61) at 5 years, and 43% (95% CI 19-78) at 10 years. Conclusion: Survivors of childhood cancer who received CRT are at high risk for first and recurrent stroke. Larger studies are needed to identify predictors of recurrence to design secondary stroke prevention strategies.
