PURPOSE Women treated with chest radiation for childhood cancer have one of the highest risks of breast cancer. Models producing personalized breast cancer risk estimates applicable to this population do not exist. We sought to develop and validate a breast cancer risk prediction model for childhood cancer survivors treated with chest radiation incorporating treatment-related factors, family history, and reproductive factors. METHODS Analyses were based on multinational cohorts of female 5-year survivors of cancer diagnosed younger than age 21 years and treated with chest radiation. Model derivation was based on 1,120 participants in the Childhood Cancer Survivor Study diagnosed between 1970 and 1986, with median attained age 42 years (range 20-64) and 242 with breast cancer. Model validation included 1,027 participants from three cohorts, with median age 32 years (range 20-66) and 105 with breast cancer. RESULTS The model included current age, chest radiation field, whether chest radiation was delivered within 1 year of menarche, anthracycline exposure, age at menopause, and history of a first-degree relative with breast cancer. Ten-year risk estimates ranged from 2% to 23% for 30-year-old women (area under the curve, 0.63; 95% CI, 0.50 to 0.73) and from 5% to 34% for 40-year-old women (area under the curve, 0.67; 95% CI, 0.54 to 0.84). The highest risks were among premenopausal women older than age 40 years treated with mantle field radiation within a year of menarche who had a first-degree relative with breast cancer. It showed good calibration with an expected-to-observed ratio of the number of breast cancers of 0.92 (95% CI, 0.74 to 1.16). CONCLUSION Breast cancer risk varies among childhood cancer survivors treated with chest radiation. Accurate risk prediction may aid in refining surveillance, counseling, and preventive strategies in this population.

Purpose Little is known about the breast cancer risk among childhood cancer survivors who did not receive chest radiotherapy. We sought to determine the magnitude of risk and associated risk factors for breast cancer among these women. Patients and Methods We evaluated cumulative breast cancer risk in 3,768 female childhood cancer survivors without a history of chest radiotherapy who were participants in the Childhood Cancer Survivor Study. Results With median follow up of 25.5 years (range, 8 to 39 years), 47 women developed breast cancer at a median age of 38.0 years (range, 22 to 47 years) and median of 24.0 years (range, 10 to 34 years) from primary cancer to breast cancer. A four-fold increased breast cancer risk (standardized incidence ratio [SIR] = 4.0; 95% CI, 3.0 to 5.3) was observed when compared with the general population. Risk was highest among sarcoma and leukemia survivors (SIR = 5.3; 95% CI, 3.6 to 7.8 and SIR = 4.1; 95% CI, 2.4 to 6.9, respectively). By the age of 45 years, the cumulative incidence of breast cancer in sarcoma and leukemia survivors was 5.8% (95% CI, 3.7 to 8.4) and 6.3% (95% CI, 3.0 to 11.3), respectively. No other primary cancer diagnosis was associated with an elevated risk. Alkylators and anthracyclines were associated with an increased breast cancer risk in a dose-dependent manner (P values from test for trend were both < .01). Conclusions Women not exposed to chest radiotherapy who survive childhood sarcoma or leukemia have an increased risk of breast cancer at a young age. The data suggest high-dose alkylator and anthracycline chemotherapy increase the risk of breast cancer. This may suggest a possible underlying gene-environment interaction that warrants further study.

Long-term adverse health conditions, including secondary malignant neoplasms, are common in childhood cancer survivors. Although mortality attributable to secondary malignancies declined over the past decades, the risk for developing a solid secondary malignant neoplasm did not. Endocrine-related malignancies are among the most common secondary malignant neoplasms observed in childhood cancer survivors. In this systematic review, we describe risk factors for secondary malignant neoplasms of the breast and thyroid, since these are the most common secondary endocrine-related malignancies in childhood cancer survivors. Radiotherapy is the most important risk factor for secondary breast and thyroid cancer in childhood cancer survivors. Breast cancer risk is especially increased in survivors of Hodgkin lymphoma who received moderate- to high-dosed mantle field irradiation. Recent studies also demonstrated an increased risk after lower-dose irradiation in other radiation fields for other childhood cancer subtypes. Premature ovarian insufficiency may protect against radiation-induced breast cancer. Although evidence is weak, estrogen–progestin replacement therapy does not seem to be associated with an increased breast cancer risk in premature ovarian-insufficient childhood cancer survivors. Radiotherapy involving the thyroid gland increases the risk for secondary differentiated thyroid carcinoma, as well as benign thyroid nodules. Currently available studies on secondary malignant neoplasms in childhood cancer survivors are limited by short follow-up durations and assessed before treatment regimens. In addition, studies on risk-modifying effects of environmental and lifestyle factors are lacking. Risk-modifying effects of premature ovarian insufficiency and estrogen–progestin replacement therapy on radiation-induced breast cancer require further study.

10053 Background: Breast cancer is a common late-effect for female childhood cancer survivors and chest radiotherapy is an established risk factor. Recent findings showed that treatment with anthracyclines also increases breast cancer risk. However, the risk from the combined effect of radiotherapy and anthracyclines is unknown. Methods: We conducted a matched case-control study of 271 subsequent breast cancer and 1044 controls nested within the CCSS - a North-American cohort of five-year survivors of childhood cancer, diagnosed from 1970-1986 and followed-up through 2016. Detailed treatment records were abstracted to estimate radiation dose (Gy) to the breast cancer location and ovaries and calculate cumulative chemotherapy doses (mg/m2). Multivariable conditional logistic regression was used to estimate Odds ratios (OR) and 95% confidence intervals (CI). Results: Breast cancer risk increased linearly with radiation dose to the breast (OR per 10Gy = 3.9, 95%CI:2.5-6.5) and decreased with increasing ovarian dose (p < 0.01). Adjusted for radiation dose, the highest quartile of dose (455+mg/m2) of anthracyclines was associated with a 3.8-fold increased risk of breast cancer (95%CI:1.8-8.2) compared to no anthracyclines. This risk increased with cumulative anthracycline dose (p-trend < 0.01) and was non-significantly higher for ER+ than ER- breast cancers. For a breast dose of 10+Gy, the OR was 19.1 (95%CI:7.6-48.0) with anthracyclines versus 9.6 (95%CI:4.4-20.7) without anthracyclines, compared to 0- < 1Gy breast dose and no anthracyclines (p-additive interaction = 0.04). Conclusions: The combination of anthracyclines and radiotherapy doses to the breast can markedly increase breast cancer risk compared to those who receive neither treatment. Our results can be used to inform risk management for childhood cancer patients treated in the past, as well as project potential breast cancer risk from current treatment protocols.

Background: Sedentary behavior is associated with increased risk of poor outcomes in breast cancer survivors, but underlying mechanisms are not well understood. This pilot study explored associations between different aspects of sedentary behaviors (sitting, prolonged sitting, sit-to-stand transitions, and standing) and breast cancer risk-related biomarkers in breast cancer survivors (n = 30). Methods: Sedentary behavior variables were objectively measured with thigh-worn activPALs. Breast cancer risk-related biomarkers assessed were C-reactive protein (CRP), insulin, and homeostatic model assessment of insulin resistance (HOMA-IR) and were measured in fasting plasma samples. Linear regression models were used to investigate associations between sedentary behavior variables and biomarkers (log CRP, insulin, and HOMA-IR). Results: Sit-to-stand transitions were significantly associated with insulin resistance biomarkers (P < .05). Specifically, each 10 additional sit-to-stand transitions per day was associated with a lower fasting insulin concentration (β = −5.52; 95% CI, −9.79 to −1.24) and a lower HOMA-IR value (β = −0.22; 95% CI, −0.42 to −0.03). Sit-to-stand transitions were not significantly associated with CRP concentration (P = .08). Total sitting time, long sitting bouts, and standing time were not significantly associated with CRP, insulin, or HOMA-IR (P > .05). Conclusions: Sit-to-stand transitions may be an intervention target for reducing insulin resistance in breast cancer survivors, which may have favorable downstream effects on cancer prognosis.

PURPOSE Female survivors of childhood cancer have a high risk of subsequent breast cancer. We describe the ensuing risk for mortality and additional breast cancers. PATIENTS AND METHODS Female participants in the Childhood Cancer Survivor Study, a cohort of 5-year survivors of cancer diagnosed between 1970 and 1986 before age 21 years, and subsequently diagnosed with breast cancer (n = 274; median age at breast cancer diagnosis, 38 years; range, 20 to 58 years) were matched to a control group (n = 1,095) with de novo breast cancer. Hazard ratios (HRs) and 95% CIs were estimated from cause-specific proportional hazards models. RESULTS Ninety-two childhood cancer survivors died, 49 as a result of breast cancer. Overall survival after breast cancer was 73% by 10 years. Subsequent risk of death as a result of any cause was higher among childhood cancer survivors than among controls (HR, 2.2; 95% CI, 1.7 to 3.0) and remained elevated after adjusting for breast cancer treatment (HR, 2.4; 95% CI, 1.7 to 3.2). Although breast cancer–specific mortality was modestly elevated among childhood cancer survivors (HR, 1.3; 95% CI, 0.9 to 2.0), survivors were five times more likely to die as a result of other health-related causes, including other subsequent malignant neoplasms and cardiovascular or pulmonary disease (HR, 5.5; 95% CI, 3.4 to 9.0). The cumulative incidence of a second asynchronous breast cancer also was elevated significantly compared with controls ( P < .001). CONCLUSION Mortality after breast cancer was higher in childhood cancer survivors than in women with de novo breast cancer. This increased mortality reflects the burden of comorbidity and highlights the need for risk-reducing interventions.
