Annual report to the nation on the status of cancer, featuring cancer in men and women age 20-49 years
Ward EM , Sherman RL , Henley SJ , Jemal A , Siegel DA , Feuer EJ , Firth AU , Kohler BA , Scott S , Ma J , Anderson RN , Benard V , Cronin KA . J Natl Cancer Inst 2019 111 (12) 1279-1297 BACKGROUND: The American Cancer Society, Centers for Disease Control and Prevention, National Cancer Institute, and North American Association of Central Cancer Registries provide annual updates on cancer occurrence and trends by cancer type, sex, race, ethnicity, and age in the United States. This year's report highlights the cancer burden among men and women age 20-49 years. METHODS: Incidence data for the years 1999 to 2015 from the Centers for Disease Control and Prevention- and National Cancer Institute-funded population-based cancer registry programs compiled by the North American Association of Central Cancer Registries and death data for the years 1999 to 2016 from the National Vital Statistics System were used. Trends in age-standardized incidence and death rates, estimated by joinpoint, were expressed as average annual percent change. RESULTS: Overall cancer incidence rates (per 100 000) for all ages during 2011-2015 were 494.3 among male patients and 420.5 among female patients; during the same time period, incidence rates decreased 2.1% (95% confidence interval [CI] = -2.6% to -1.6%) per year in men and were stable in females. Overall cancer death rates (per 100 000) for all ages during 2012-2016 were 193.1 among male patients and 137.7 among female patients. During 2012-2016, overall cancer death rates for all ages decreased 1.8% (95% CI = -1.8% to -1.8%) per year in male patients and 1.4% (95% CI = -1.4% to -1.4%) per year in females. Important changes in trends were stabilization of thyroid cancer incidence rates in women and rapid declines in death rates for melanoma of the skin (both sexes). Among adults age 20-49 years, overall cancer incidence rates were substantially lower among men (115.3 per 100 000) than among women (203.3 per 100 000); cancers with the highest incidence rates (per 100 000) among men were colon and rectum (13.1), testis (10.7), and melanoma of the skin (9.8), and among women were breast (73.2), thyroid (28.4), and melanoma of the skin (14.1). During 2011 to 2015, the incidence of all invasive cancers combined among adults age 20-49 years decreased -0.7% (95% CI = -1.0% to -0.4%) among men and increased among women (1.3%, 95% CI = 0.7% to 1.9%). The death rate for (per 100 000) adults age 20-49 years for all cancer sites combined during 2012 to 2016 was 22.8 among men and 27.1 among women; during the same time period, death rates decreased 2.3% (95% CI = -2.4% to -2.2%) per year among men and 1.7% (95% CI = -1.8% to -1.6%) per year among women. CONCLUSIONS: Among people of all ages and ages 20-49 years, favorable as well as unfavorable trends in site-specific cancer incidence were observed, whereas trends in death rates were generally favorable. Characterizing the cancer burden may inform research and cancer-control efforts. |
Annual Report to the Nation on the Status of Cancer, Part 2: Patient Economic Burden Associated With Cancer Care
Yabroff KR , Mariotto A , Tangka F , Zhao J , Islami F , Sung H , Sherman RL , Henley SJ , Jemal A , Ward EM . J Natl Cancer Inst 2021 113 (12) 1670-1682 BACKGROUND: The American Cancer Society, National Cancer Institute, Centers for Disease Control and Prevention, and North American Association of Central Cancer Registries provide annual information about cancer occurrence and trends in the United States. Part 1 of this annual report focuses on national cancer statistics. This study is part 2, which quantifies patient economic burden associated with cancer care. METHODS: We used complementary data sources, linked Surveillance, Epidemiology, and End Results-Medicare, and the Medical Expenditure Panel Survey to develop comprehensive estimates of patient economic burden, including out-of-pocket and patient time costs, associated with cancer care. The 2000-2013 Surveillance, Epidemiology, and End Results-Medicare data were used to estimate net patient out-of-pocket costs among adults aged 65 years and older for the initial, continuing, and end-of-life phases of care for all cancer sites combined and separately for the 21 most common cancer sites. The 2008-2017 Medical Expenditure Panel Survey data were used to calculate out-of-pocket costs and time costs associated with cancer among adults aged 18-64 years and 65 years and older. RESULTS: Across all cancer sites, annualized net out-of-pocket costs for medical services and prescriptions drugs covered through a pharmacy benefit among adults aged 65 years and older were highest in the initial ($2200 and $243, respectively) and end-of-life phases ($3823 and $448, respectively) and lowest in the continuing phase ($466 and $127, respectively), with substantial variation by cancer site. Out-of-pocket costs were generally higher for patients diagnosed with later-stage disease. Net annual time costs associated with cancer were $304.3 (95% confidence interval = $257.9 to $350.9) and $279.1 (95% confidence interval = $215.1 to $343.3) for adults aged 18-64 years and ≥65 years, respectively, with higher time costs among more recently diagnosed survivors. National patient economic burden, including out-of-pocket and time costs, associated with cancer care was projected to be $21.1 billion in 2019. CONCLUSIONS: This comprehensive study found that the patient economic burden associated with cancer care is substantial in the United States at the national and patient levels. |
Annual Report to the Nation on the Status of Cancer, Part 1: National Cancer Statistics
Islami F , Ward EM , Sung H , Cronin KA , Tangka FKL , Sherman RL , Zhao J , Anderson RN , Henley SJ , Yabroff KR , Jemal A , Benard VB . J Natl Cancer Inst 2021 113 (12) 1648-1669 BACKGROUND: The American Cancer Society, Centers for Disease Control and Prevention, National Cancer Institute, and North American Association of Central Cancer Registries collaborate to provide annual updates on cancer incidence and mortality and trends by cancer type, sex, age group, and racial/ethnic group in the United States. In this report, we also examine trends in stage-specific survival for melanoma of the skin (melanoma). METHODS: Incidence data for all cancers from 2001 through 2017 and survival data for melanoma cases diagnosed during 2001-2014 and followed up through 2016 were obtained from the Centers for Disease Control and Prevention- and National Cancer Institute-funded population-based cancer registry programs compiled by the North American Association of Central Cancer Registries. Data on cancer deaths from 2001 through 2018 were obtained from the National Center for Health Statistics' National Vital Statistics System. Trends in age-standardized incidence and death rates and 2-year relative survival were estimated by joinpoint analysis, and trends in incidence and mortality were expressed as average annual percent change (AAPC) during the most recent 5 years (2013-2017 for incidence and 2014-2018 for mortality). RESULTS: Overall cancer incidence rates (per 100,000 population) for all ages during 2013-2017 were 487.4 among males and 422.4 among females. During this period, incidence rates remained stable among males but slightly increased in females (AAPC = 0.2%; 95% confidence interval [CI] = 0.1% to 0.2%). Overall cancer death rates (per 100,000 population) during 2014-2018 were 185.5 among males and 133.5 among females. During this period, overall death rates decreased in both males (AAPC = -2.2%; 95% CI = -2.5% to - 1.9%) and females (AAPC = -1.7%; 95% CI = -2.1% to - 1.4%); death rates decreased for 11 of the 19 most common cancers among males and for 14 of the 20 most common cancers among females, but increased for 5 cancers in each sex. During 2014-2018, the declines in death rates accelerated for lung cancer and melanoma, slowed down for colorectal and female breast cancers, and leveled off for prostate cancer. Among children younger than age 15 years and adolescents and young adults aged 15-39 years, cancer death rates continued to decrease in contrast to the increasing incidence rates. Two-year relative survival for distant-stage skin melanoma was stable for those diagnosed during 2001-2009 but increased by 3.1% (95% CI = 2.8% to 3.5%) per year for those diagnosed during 2009-2014, with comparable trends among males and females. CONCLUSIONS: Cancer death rates in the United States continue to decline overall and for many cancer types, with the decline accelerated for lung cancer and melanoma. For several other major cancers, however, death rates continue to increase or previous declines in rates have slowed or ceased. Moreover, overall incidence rates continue to increase among females, children, and adolescents and young adults. These findings inform efforts related to prevention, early detection, and treatment and for broad and equitable implementation of effective interventions, especially among under-resourced populations. |
Annual report to the nation on the status of cancer, part I: National cancer statistics
Henley SJ , Ward EM , Scott S , Ma J , Anderson RN , Firth AU , Thomas CC , Islami F , Weir HK , Lewis DR , Sherman RL , Wu M , Benard VB , Richardson LC , Jemal A , Cronin K , Kohler BA . Cancer 2020 126 (10) 2225-2249 BACKGROUND: The American Cancer Society, the Centers for Disease Control and Prevention, the National Cancer Institute, and the North American Association of Central Cancer Registries collaborate to provide annual updates on cancer occurrence and trends in the United States. METHODS: Data on new cancer diagnoses during 2001 through 2016 were obtained from the Centers for Disease Control and Prevention-funded and National Cancer Institute-funded population-based cancer registry programs and compiled by the North American Association of Central Cancer Registries. Data on cancer deaths during 2001 through 2017 were obtained from the National Center for Health Statistics' National Vital Statistics System. Trends in incidence and death rates for all cancers combined and for the leading cancer types by sex, racial/ethnic group, and age were estimated by joinpoint analysis and characterized by the average annual percent change during the most recent 5 years (2012-2016 for incidence and 2013-2017 for mortality). RESULTS: Overall, cancer incidence rates decreased 0.6% on average per year during 2012 through 2016, but trends differed by sex, racial/ethnic group, and cancer type. Among males, cancer incidence rates were stable overall and among non-Hispanic white males but decreased in other racial/ethnic groups; rates increased for 5 of the 17 most common cancers, were stable for 7 cancers (including prostate), and decreased for 5 cancers (including lung and bronchus [lung] and colorectal). Among females, cancer incidence rates increased during 2012 to 2016 in all racial/ethnic groups, increasing on average 0.2% per year; rates increased for 8 of the 18 most common cancers (including breast), were stable for 6 cancers (including colorectal), and decreased for 4 cancers (including lung). Overall, cancer death rates decreased 1.5% on average per year during 2013 to 2017, decreasing 1.8% per year among males and 1.4% per year among females. During 2013 to 2017, cancer death rates decreased for all cancers combined among both males and females in each racial/ethnic group, for 11 of the 19 most common cancers among males (including lung and colorectal), and for 14 of the 20 most common cancers among females (including lung, colorectal, and breast). The largest declines in death rates were observed for melanoma of the skin (decreasing 6.1% per year among males and 6.3% among females) and lung (decreasing 4.8% per year among males and 3.7% among females). Among children younger than 15 years, cancer incidence rates increased an average of 0.8% per year during 2012 to 2016, and cancer death rates decreased an average of 1.4% per year during 2013 to 2017. Among adolescents and young adults aged 15 to 39 years, cancer incidence rates increased an average of 0.9% per year during 2012 to 2016, and cancer death rates decreased an average of 1.0% per year during 2013 to 2017. CONCLUSIONS: Although overall cancer death rates continue to decline, incidence rates are leveling off among males and are increasing slightly among females. These trends reflect population changes in cancer risk factors, screening test use, diagnostic practices, and treatment advances. Many cancers can be prevented or treated effectively if they are found early. Population-based cancer incidence and mortality data can be used to inform efforts to decrease the cancer burden in the United States and regularly monitor progress toward goals. |
Annual Report to the Nation on the Status of Cancer, part II: Progress toward Healthy People 2020 objectives for 4 common cancers
Henley SJ , Thomas CC , Lewis DR , Ward EM , Islami F , Wu M , Weir HK , Scott S , Sherman RL , Ma J , Kohler BA , Cronin K , Jemal A , Benard VB , Richardson LC . Cancer 2020 126 (10) 2250-2266 BACKGROUND: The Centers for Disease Control and Prevention, the American Cancer Society, the National Cancer Institute, and the North American Association of Central Cancer Registries collaborate to provide annual updates on cancer occurrence and trends in the United States and to address a special topic of interest. Part I of this report focuses on national cancer statistics, and part 2 characterizes progress in achieving select Healthy People 2020 cancer objectives. METHODS: For this report, the authors selected objectives-including death rates, cancer screening, and major risk factors-related to 4 common cancers (lung, colorectal, female breast, and prostate). Baseline values, recent values, and the percentage change from baseline to recent values were examined overall and by select sociodemographic characteristics. Data from national surveillance systems were obtained from the Healthy People 2020 website. RESULTS: Targets for death rates were met overall and in most sociodemographic groups, but not among males, blacks, or individuals in rural areas, although these groups did experience larger decreases in rates compared with other groups. During 2007 through 2017, cancer death rates decreased 15% overall, ranging from -4% (rural) to -22% (metropolitan). Targets for breast and colorectal cancer screening were not yet met overall or in any sociodemographic groups except those with the highest educational attainment, whereas lung cancer screening was generally low (<10%). Targets were not yet met overall for cigarette smoking, recent smoking cessation, excessive alcohol use, or obesity but were met for secondhand smoke exposure and physical activity. Some sociodemographic groups did not meet targets or had less improvement than others toward reaching objectives. CONCLUSIONS: Monitoring trends in cancer risk factors, screening test use, and mortality can help assess the progress made toward decreasing the cancer burden in the United States. Although many interventions to reduce cancer risk factors and promote healthy behaviors are proven to work, they may not be equitably applied or work well in every community. Implementing cancer prevention and control interventions that are sustainable, focused, and culturally appropriate may boost success in communities with the greatest need, ensuring that all Americans can access a path to long, healthy, cancer-free lives. |
Cancer collection efforts in the United States provide clinically relevant data on all primary brain and other CNS tumors
Kruchko C , Gittleman H , Ruhl J , Hofferkamp J , Ward EM , Ostrom QT , Sherman RL , Jones SF , Barnholtz-Sloan JS , Wilson RJ . Neurooncol Pract 2019 6 (5) 330-339 Cancer surveillance is critical for monitoring the burden of cancer and the progress in cancer control. The accuracy of these data is important for decision makers and others who determine resource allocation for cancer prevention and research. In the United States, cancer registration is conducted according to uniform data standards, which are updated and maintained by the North American Association of Central Cancer Registries. Underlying cancer registration efforts is a firm commitment to ensure that data are accurate, complete, and reflective of current clinical practices. Cancer registries ultimately depend on medical records that are generated for individual patients by clinicians to record newly diagnosed cases. For the cancer registration of brain and other CNS tumors, the Central Brain Tumor Registry of the United States is the self-appointed guardian of these data. In 2017, the Central Brain Tumor Registry of the United States took the initiative to promote the inclusion of molecular markers found in the 2016 WHO Classification of Tumours of the Central Nervous System into information collected by cancer registries. The complexities of executing this latest objective are presented according to the cancer registry standard-setting organizations whose collection practices for CNS tumors are directly affected. |
Chromosome Translocations and Cosmic Radiation Dose in Male U.S. Commercial Airline Pilots.
Grajewski B , Yong LC , Bertke SJ , Bhatti P , Little MP , Ramsey MJ , Tucker JD , Ward EM , Whelan EA , Sigurdson AJ , Waters MA . Aerosp Med Hum Perform 2018 89 (7) 616-625 BACKGROUND: Chromosome translocations are a biomarker of cumulative exposure to ionizing radiation. We examined the relation between the frequency of translocations and cosmic radiation dose in 83 male airline pilots. METHODS: Translocations were scored using fluorescence in situ hybridization chromosome painting. Cumulative radiation doses were estimated from individual flight records. Excess rate and log-linear Poisson regression models were evaluated. RESULTS: Pilots' estimated median cumulative absorbed dose was 15 mGy (range 4.5-38). No association was observed between translocation frequency and absorbed dose from all types of flying [rate ratio (RR) = 1.01 at 1 mGy, 95% confidence interval (CI) 0.97-1.04]. However, additional analyses of pilots' dose from only commercial flying suggested an association (RR = 1.04 at 1 mGy, 95% CI 0.97-1.13). DISCUSSION: Although this is the largest cytogenetic study of male commercial airline pilots to date of which the authors are aware, future studies will need additional highly exposed pilots to better assess the translocation-cosmic radiation relation. |
Annual Report to the Nation on the Status of Cancer, 1975-2014, featuring survival
Jemal A , Ward EM , Johnson CJ , Cronin KA , Ma J , Ryerson B , Mariotto A , Lake AJ , Wilson R , Sherman RL , Anderson RN , Henley SJ , Kohler BA , Penberthy L , Feuer EJ , Weir HK . J Natl Cancer Inst 2017 109 (9) Background: The American Cancer Society (ACS), the Centers for Disease Control and Prevention (CDC), the National Cancer Institute (NCI), and the North American Association of Central Cancer Registries (NAACCR) collaborate to provide annual updates on cancer occurrence and trends in the United States. This Annual Report highlights survival rates. Data were from the CDC- and NCI-funded population-based cancer registry programs and compiled by NAACCR. Trends in age-standardized incidence and death rates for all cancers combined and for the leading cancer types by sex were estimated by joinpoint analysis and expressed as annual percent change. We used relative survival ratios and adjusted relative risk of death after a diagnosis of cancer (hazard ratios [HRs]) using Cox regression model to examine changes or differences in survival over time and by sociodemographic factors. Results: Overall cancer death rates from 2010 to 2014 decreased by 1.8% (95% confidence interval [CI] = -1.8 to -1.8) per year in men, by 1.4% (95% CI = -1.4 to -1.3) per year in women, and by 1.6% (95% CI = -2.0 to -1.3) per year in children. Death rates decreased for 11 of the 16 most common cancer types in men and for 13 of the 18 most common cancer types in women, including lung, colorectal, female breast, and prostate, whereas death rates increased for liver (men and women), pancreas (men), brain (men), and uterine cancers. In contrast, overall incidence rates from 2009 to 2013 decreased by 2.3% (95% CI = -3.1 to -1.4) per year in men but stabilized in women. For several but not all cancer types, survival statistically significantly improved over time for both early and late-stage diseases. Between 1975 and 1977, and 2006 and 2012, for example, five-year relative survival for distant-stage disease statistically significantly increased from 18.7% (95% CI = 16.9% to 20.6%) to 33.6% (95% CI = 32.2% to 35.0%) for female breast cancer but not for liver cancer (from 1.1%, 95% CI = 0.3% to 2.9%, to 2.3%, 95% CI = 1.6% to 3.2%). Survival varied by race/ethnicity and state. For example, the adjusted relative risk of death for all cancers combined was 33% (HR = 1.33, 95% CI = 1.32 to 1.34) higher in non-Hispanic blacks and 51% (HR = 1.51, 95% CI = 1.46 to 1.56) higher in non-Hispanic American Indian/Alaska Native compared with non-Hispanic whites. Conclusions: Cancer death rates continue to decrease in the United States. However, progress in reducing death rates and improving survival is limited for several cancer types, underscoring the need for intensified efforts to discover new strategies for prevention, early detection, and treatment and to apply proven preventive measures broadly and equitably. |
Diagnostic X-ray examinations and increased chromosome translocations: evidence from three studies
Bhatti P , Yong LC , Doody MM , Preston DL , Kampa DM , Ramsey MJ , Ward EM , Edwards AA , Ron E , Tucker JD , Sigurdson AJ . Radiat Environ Biophys 2010 49 (4) 685-92 Controversy regarding potential health risks from increased use of medical diagnostic radiologic examinations has come to public attention. We evaluated whether chromosome damage, specifically translocations, which are a potentially intermediate biomarker for cancer risk, was increased after exposure to diagnostic X-rays, with particular interest in the ionizing radiation dose-response below the level of approximately 50 mGy. Chromosome translocation frequency data from three separately conducted occupational studies of ionizing radiation were pooled together. Studies 1 and 2 included 79 and 150 medical radiologic technologists, respectively, and study 3 included 83 airline pilots and 50 university faculty members (total = 155 women and 207 men; mean age = 62 years, range 34-90). Information on personal history of radiographic examinations was collected from a detailed questionnaire. We computed a cumulative red bone marrow (RBM) dose score based on the numbers and types of X-ray examinations reported with 1 unit approximating 1 mGy. Poisson regression analyses were adjusted for age and laboratory method. Mean RBM dose scores were 49, 42, and 11 for Studies 1-3, respectively (overall mean = 33.5, range 0-303). Translocation frequencies significantly increased with increasing dose score (P < 0.001). Restricting the analysis to the lowest dose scores of under 50 did not materially change these results. We conclude that chromosome damage is associated with low levels of radiation exposure from diagnostic X-ray examinations, including dose scores of approximately 50 and lower, suggesting the possibility of long-term adverse health effects. |
Research recommendations for selected IARC-classified agents
Ward EM , Schulte PA , Straif K , Hopf NB , Caldwell JC , Carreon T , Demarini DM , Fowler BA , Goldstein BD , Hemminki K , Hines CJ , Husgafvel Pursiainen K , Kuempel E , Lewtas J , Lunn RM , Lynge E , McElvenny DM , Muhle H , Nakajima T , Robertson LW , Ruder AM , Schubauer-Berigan MK . Environ Health Perspect 2010 118 (10) 1355-62 OBJECTIVES: There are some common occupational agents and exposure circumstances where evidence of carcinogenicity is substantial but not yet conclusive for humans. The objectives are to identify research gaps and needs for twenty agents prioritized for review based on evidence of widespread human exposures and potential carcinogenicity in animals or humans. DATA SOURCES: A systematic review was conducted of new data published since the most recent pertinent IARC monograph meeting. DATA EXTRACTION: Reviewers were charged with identifying data gaps and general and specific approaches to address them, focusing on research that would be important in resolving classification uncertainties. An expert meeting brought reviewers together to discuss each agent and the identified data gaps and approaches. DATA SYNTHESIS: Several overarching issues were identified that pertained to multiple agents; these included the importance of recognizing that carcinogenic agents can act through multiple toxicity pathways and mechanisms, including epigenetic mechanisms, oxidative stress and immuno- and hormonal modulation. CONCLUSIONS: Studies in occupational populations provide important opportunities to understand the mechanisms through which exogenous agents cause cancer and intervene to prevent human exposure and/or prevent or detect cancer among those already exposed. Scientific developments are likely to increase the challenges and complexities of carcinogen testing and evaluation in the future, and epidemiologic studies will be particularly critical to inform carcinogen classification and risk assessment processes. |
Increased bladder cancer risk among workers exposed to o-toluidine and aniline: a reanalysis
Carreon T , Hein MJ , Viet SM , Hanley KW , Ruder AM , Ward EM . Occup Environ Med 2009 67 (5) 348-50 INTRODUCTION: In 1991, the U.S. National Institute for Occupational Safety and Health (NIOSH) reported an increased bladder cancer risk in a cohort of 1749 workers potentially exposed to o-toluidine and aniline at a chemical manufacturing plant. Additional information showed that workers in certain departments had been misclassified regarding o-toluidine exposure; therefore, we conducted a reanalysis of the data using updated exposure categories. METHODS: We updated exposure categories based on information ascertained during a plant walkthrough, documents on file at the plant, interviews with current and former employees, and answers provided by company and union officials on specific questions. Bladder cancer incidence was determined through 31 December 1988 and mortality through 31 December 1994. RESULTS: Thirteen cases of bladder cancer were observed, versus 3.57 expected (New York State rates excluding New York City) [standardized incidence ratio (SIR) 3.64, 95% confidence interval (CI) 1.94-6.23]. Among workers classified as definitely exposed, increasing risks were observed for longer duration of employment [for ≥10 years, standardized rate ratio (SRR) 6.07, 95% CI 0.77-48.17] and time since first employment in the exposed departments (for ≥20 years, SRR 3.39, 95% CI 0.40-29.03). One bladder cancer death was observed among those definitely exposed. CONCLUSION: These findings are comparable to the results reported earlier by NIOSH, and confirm that workers in this plant have an increased risk of bladder cancer. |
High dietary antioxidant intakes are associated with decreased chromosome translocation frequency in airline pilots
Yong LC , Petersen MR , Sigurdson AJ , Sampson LA , Ward EM . Am J Clin Nutr 2009 90 (5) 1402-10 BACKGROUND: Dietary antioxidants may protect against DNA damage induced by endogenous and exogenous sources, including ionizing radiation (IR), but data from IR-exposed human populations are limited. OBJECTIVE: The objective was to examine the association between the frequency of chromosome translocations, as a biomarker of cumulative DNA damage, and intakes of vitamins C and E and carotenoids in 82 male airline pilots. DESIGN: Dietary intakes were estimated by using a self-administered semiquantitative food-frequency questionnaire. Translocations were scored by using fluorescence in situ hybridization with whole chromosome paints. Negative binomial regression was used to estimate rate ratios and 95% CIs, adjusted for potential confounders. RESULTS: Significant and inverse associations were observed between translocation frequency and intakes of vitamin C, beta-carotene, beta-cryptoxanthin, and lutein-zeaxanthin from food (P < 0.05). Translocation frequency was not associated with the intake of vitamin E, alpha-carotene, or lycopene from food; total vitamin C or E from food and supplements; or vitamin C or E or multivitamin supplements. The adjusted rate ratios (95% CI) for ≥median compared with <median servings per week of high-vitamin C fruit and vegetables, citrus fruit, and green leafy vegetables were 0.61 (0.43, 0.86), 0.64 (0.46, 0.89), and 0.59 (0.43, 0.81), respectively. The strongest inverse association was observed for ≥median compared with <median combined intakes of vitamins C and E, beta-carotene, beta-cryptoxanthin, and lutein-zeaxanthin from food: 0.27 (0.14, 0.55). CONCLUSION: High combined intakes of vitamins C and E, beta-carotene, beta-cryptoxanthin, and lutein-zeaxanthin from food, or a diet high in their food sources, may protect against cumulative DNA damage in IR-exposed persons. |
