Use of Adjuvant Chemotherapy among Stage II Colon Cancer Patients in 10 Population-Based National Program of Cancer Registries
Eheman CR , O'Neil ME , Styles TS , Thompson TD , Morris CR , Babcock FA , Chen VW . J Registry Manag 2016 43 (4) 179-186 BACKGROUND: Some guidelines advise adjuvant chemotherapy be considered after surgical resection for high-risk stage II colon cancer patients; however, high-risk criteria are poorly defined and the long-term benefits are still debated. This study documents patterns of care by selected patient and tumor characteristics using a US population-based cohort of stage II colon cancer patients diagnosed in 2011. METHODS: Data were collected from 10 specialized cancer registries participating in the Centers for Disease Control and Prevention's National Program of Cancer Registries' Enhancing Cancer Registry Data for Comparative Effectiveness Research project. The data were used to describe characteristics of stage II colon cancer patients treated by surgery to evaluate factors associated with receiving adjuvant chemotherapy. RESULTS: Of the 3,891 stage II colon cancer patients, 14.3% were treated with surgery and adjuvant chemotherapy compared to 82.9% by surgery alone. The patients treated with adjuvant chemotherapy were predominately non-Hispanic white (66.1%), of younger age, and had private insurance (39.9%). Compared to surgery alone, the 5 characteristics associated with adjuvant therapy were younger age (adjusted odds ratio [AOR] for 5-year decrease below 75 years, 1.25; P < .001); more advanced stage (IIB/IIC vs IIA) (AOR, 4.79; P < .001); lymphovascular invasion (AOR, 1.76, P < .001); higher grade (III/IV vs I/II) (AOR, 1.84; P < .001); and registry area. CONCLUSIONS: In this population-based cohort, younger patients with more advanced stage II colon tumors, with lymphovascular invasion, and poor differentiation were more likely to receive adjuvant chemotherapy in addition to surgery. These characteristics align with high-risk profiles defined in guidelines. Ongoing data collection on outcomes, including recurrence and survival, will help clarify the benefits of adjuvant treatments for stage II colon patients. |
Annual report to the nation on the status of cancer, 1975-2012, featuring the increasing incidence of liver cancer
Ryerson AB , Eheman CR , Altekruse SF , Ward JW , Jemal A , Sherman RL , Henley SJ , Holtzman D , Lake A , Noone AM , Anderson RN , Ma J , Ly KN , Cronin KA , Penberthy L , Kohler BA . Cancer 2016 122 (9) 1312-37 BACKGROUND: Annual updates on cancer occurrence and trends in the United States are provided through an ongoing collaboration among 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). This annual report highlights the increasing burden of liver and intrahepatic bile duct (liver) cancers. METHODS: Cancer incidence data were obtained from the CDC, NCI, and NAACCR; data about cancer deaths were obtained from the CDC's National Center for Health Statistics (NCHS). Annual percent changes in incidence and death rates (age-adjusted to the 2000 US Standard Population) for all cancers combined and for the leading cancers among men and women were estimated by joinpoint analysis of long-term trends (incidence for 1992-2012 and mortality for 1975-2012) and short-term trends (2008-2012). In-depth analysis of liver cancer incidence included an age-period-cohort analysis and an incidence-based estimation of person-years of life lost because of the disease. By using NCHS multiple causes of death data, hepatitis C virus (HCV) and liver cancer-associated death rates were examined from 1999 through 2013. RESULTS: Among men and women of all major racial and ethnic groups, death rates continued to decline for all cancers combined and for most cancer sites; the overall cancer death rate (for both sexes combined) decreased by 1.5% per year from 2003 to 2012. Overall, incidence rates decreased among men and remained stable among women from 2003 to 2012. Among both men and women, deaths from liver cancer increased at the highest rate of all cancer sites, and liver cancer incidence rates increased sharply, second only to thyroid cancer. Men had more than twice the incidence rate of liver cancer than women, and rates increased with age for both sexes. Among non-Hispanic (NH) white, NH black, and Hispanic men and women, liver cancer incidence rates were higher for persons born after the 1938 to 1947 birth cohort. In contrast, there was a minimal birth cohort effect for NH Asian and Pacific Islanders (APIs). NH black men and Hispanic men had the lowest median age at death (60 and 62 years, respectively) and the highest average person-years of life lost per death (21 and 20 years, respectively) from liver cancer. HCV and liver cancer-associated death rates were highest among decedents who were born during 1945 through 1965. CONCLUSIONS: Overall, cancer incidence and mortality declined among men; and, although cancer incidence was stable among women, mortality declined. The burden of liver cancer is growing and is not equally distributed throughout the population. Efforts to vaccinate populations that are vulnerable to hepatitis B virus (HBV) infection and to identify and treat those living with HCV or HBV infection, metabolic conditions, alcoholic liver disease, or other causes of cirrhosis can be effective in reducing the incidence and mortality of liver cancer.

Connecting the dots: Linking the National Program of Cancer Registries and the needs of survivors and clinicians
Ryerson AB , Eheman C , Styles T , Rycroft R , Snyder C . Am J Prev Med 2015 49 S528-35 Cancer survivors, the medical community, public health professionals, researchers, and policymakers all need information about newly diagnosed cancer cases and deaths to better understand and address the disease burden. CDC collects cancer data on 96% of the U.S. population through the National Program of Cancer Registries. The National Program of Cancer Registries routinely collects data on all cancer occurrences, deaths, and the types of initial treatment received by the patients, and recently CDC has made advances in its cancer surveillance activities that have direct applicability to cancer survivorship research and care. This article examines CDC's innovative uses of the National Program of Cancer Registries infrastructure and data as a recruitment source for survivorship research studies and behavioral interventions; comparative effectiveness and patient-centered outcomes research; and the collection, consolidation, and dissemination of treatment summaries for cancer survivors and their providers. This paper also discusses long-term, idealistic plans for additional data linkages and sharing among public health, providers, and the cancer survivor through innovative concepts such as patient portals and rapid-learning health care. |
Racial disparities in prostate cancer incidence rates by census division in the United States, 1999-2008
Cook MB , Rosenberg PS , McCarty FA , Wu M , King J , Eheman C , Anderson WF . Prostate 2015 75 (7) 758-63 BACKGROUND: Black men have a higher incidence of prostate cancer than white men in the U.S., but little is known whether incidence or racial differences vary geographically. Understanding these differences may assist future studies on causes of prostate cancer. To address such, we leverage the unique resource of the National Program of Cancer Registries (NPCR) combined with Surveillance, Epidemiology and End Results (SEER). METHODS: Prostate cancer counts and population denominators by race (black, white), age, calendar year, and U.S. census division, for the period 1999-2008, were extracted from NPCR and SEER. We calculated age-standardized incidence rates (ASR) and estimated annual percent changes (EAPC) by race and census division. We assessed black-to-white incidence rate ratios (BWIRR) by census division and by calendar period. RESULTS: This analysis included 1,713,471 prostate cancer cases and 1,217 million person-years. Black ASRs ranged from 176 per 100,000 person-years in Mountain division to 259 in Middle Atlantic. BWIRRs ranged from 1.20 in Western divisions to 1.72 in Southeastern divisions. EAPCs indicated that prostate cancer incidence is not decreasing in East South Central, unlike all other divisions. White EAPCs displayed similar variations by census division, resulting in modest temporal changes in BWIRRs. CONCLUSIONS: Within the U.S., there exists significant geographic variability in prostate cancer incidence rates. Although there are large geographic differences in BWIRRs, temporal trends are fairly stable. This may indicate that primary factors affecting prostate cancer incidence rates vary geographically but affect both black and white men to a similar degree. Prostate 75: 758-763, 2015.

Annual Report to the Nation on the Status of Cancer, 1975-2011, featuring incidence of breast cancer subtypes by race/ethnicity, poverty, and state
Kohler BA , Sherman RL , Howlader N , Jemal A , Ryerson AB , Henry KA , Boscoe FP , Cronin KA , Lake A , Noone AM , Henley SJ , Eheman CR , Anderson RN , Penberthy L . J Natl Cancer Inst 2015 107 (6) djv048 BACKGROUND: The American Cancer Society (ACS), Centers for Disease Control and Prevention (CDC), National Cancer Institute (NCI), and North American Association of Central Cancer Registries (NAACCR) collaborate annually to produce updated, national cancer statistics. This Annual Report includes a focus on breast cancer incidence by subtype using new, national-level data. METHODS: Population-based cancer trends and breast cancer incidence by molecular subtype were calculated. Breast cancer subtypes were classified using tumor biomarkers for hormone receptor (HR) and human growth factor-neu receptor (HER2) expression. RESULTS: Overall cancer incidence increased for men by 1.8% annually from 2007 to 2011. Rates for women were stable from 1998 to 2011. Within these trends there was racial/ethnic variation, and some sites have increasing rates. Among children, incidence rates continued to increase by 0.8% per year over the past decade while, like adults, mortality declined. HR+/HER2- breast cancers, the subtype with the best prognosis, were the most common for all races/ethnicities with highest rates among non-Hispanic white women, local stage cases, and low poverty areas (92.7, 63.51, and 98.69 per 100000 non-Hispanic white women, respectively). HR+/HER2- breast cancer incidence rates were strongly, positively correlated with mammography use, particularly for non-Hispanic white women (Pearson 0.57, two-sided P < .001). Triple-negative breast cancers, the subtype with the worst prognosis, were highest among non-Hispanic black women (27.2 per 100000 non-Hispanic black women), which is reflected in high rates in southeastern states. CONCLUSIONS: Progress continues in reducing the burden of cancer in the United States. There are unique racial/ethnic-specific incidence patterns for breast cancer subtypes; likely because of both biologic and social risk factors, including variation in mammography use. Breast cancer subtype analysis confirms the capacity of cancer registries to adjust national collection standards to produce clinically relevant data based on evolving medical knowledge. |
A comparative analysis of breast cancer stage between women enrolled in the National Breast and Cervical Cancer Early Detection Program and women not participating in the program
Wu M , Austin H , Eheman CR , Myles Z , Miller J , Royalty J , Ryerson AB . Cancer Causes Control 2015 26 (5) 751-8 PURPOSE: To determine the proportional distribution of early- and late-stage breast cancers diagnosed in years 2004-2009 among women enrolled in the National Breast and Cervical Cancer Early Detection Program (NBCCEDP) and to compare this distribution to that of geographically comparable non-enrolled women diagnosed with breast cancer. METHODS: Using data from the National Program of Cancer Registries, we compared the demographic characteristics and cancer stage distribution of women enrollees and non-enrollees by use of conditional logistic regression using the odds ratio as a measure of association. RESULTS: NBCCEDP enrollees were slightly younger and more likely to identify as African-American, API and AIAN than were non-enrollees. The proportion of late-stage breast cancer (regional and distant) decreased slightly over the study period. NBCCEDP enrollees generally were diagnosed at a later stage of breast cancer than were those not enrolled in the NBCCEDP. CONCLUSIONS: The NBCCEDP has been effective in achieving its goal of enrolling racial and ethnic populations; however, enrollees had a poorer stage distribution of breast cancer than did non-enrollees underscoring the need to expand breast cancer control efforts among low-income, underserved populations. |
Reported breast symptoms in the National Breast and Cervical Cancer Early Detection Program
Ryerson AB , Miller J , Eheman CR . Cancer Causes Control 2015 26 (5) 733-40 PURPOSE: The frequency and types of breast symptoms reported by women in the National Breast and Cervical Cancer Early Detection Program (NBCCEDP) have never been characterized. This study aims to establish the frequency of reported symptoms and the diagnostic outcomes associated with reported symptoms. METHODS: We examined the frequency of symptoms reported prior to mammography using medical record abstraction data from women in the NBCCEDP. We also calculated adjusted odds ratios (aOR) of having an abnormal mammogram, an abnormal clinical breast examination, or a final diagnosis of breast cancer by symptoms, compared to asymptomatic women. RESULTS: In our sample of women, 10.3 % reported at least one symptom. Women with symptoms were younger and more likely to be non-Hispanic white. Among those reporting symptoms, breast lump (31.7 %) and pain or tenderness (49.3 %) was most common. A relatively low proportion of women with symptoms were diagnosed with in situ (0.9 %) or invasive breast cancer (4.3 %). However, a self-reported breast lump [aOR 13.7; 95 % confidence interval (CI) 7.8-24.1], inflammation or changes to the skin/nipple (aOR 27.8; 95 % CI 8.7-88.8), and other or unspecified symptoms (aOR 3.4; 95 % CI 2.1-7.5) were associated with an increased risk of invasive breast cancer. CONCLUSIONS: Although the prevalence of breast cancer among women reporting symptoms is relatively low, knowing which symptoms carry the highest breast cancer risk is important to assist in appropriate diagnostic workup. |
National Breast and Cervical Cancer Early Detection Program data validation project
Eheman CR , Leadbetter S , Benard VB , Blythe Ryerson A , Royalty JE , Blackman D , Pollack LA , Adams PW , Babcock F . Cancer 2014 120 Suppl 16 2597-603 BACKGROUND: The objectives of this study were to evaluate the quality of national data generated by the National Breast and Cervical Cancer Early Detection Program (NBCCEDP); to assess variables collected through the program that are appropriate to use for program management, evaluation, and data analysis; and to identify potential data-quality issues. METHODS: Information was abstracted randomly from 5603 medical records selected from 6 NBCCEDP-funded state programs, and 76 categorical variables and 11 text-based breast and cervical cancer screening and diagnostic variables were collected. Concordance was estimated between abstracted data and the data collected by the NBCCEDP. Overall and outcome-specific concordance was calculated for each of the key variables. Four screening performance measures also were estimated by comparing the program data with the abstracted data. RESULTS: Basic measures of program outcomes, such as the percentage of women with cancer or with abnormal screening tests, had a high concordance rate. Variables with poor or inconsistent concordance included reported breast symptoms, receipt of fine-needle aspiration, and receipt of colposcopy with biopsy. CONCLUSIONS: The overall conclusion from this comprehensive validation project of the NBCCEDP is that, with few exceptions, the data collected from individual program sites and reported to the CDC are valid and consistent with sociodemographic and clinical data within medical records. |
Lung cancer incidence trends
Henley SJ , Richards TB , Underwood JM , Eheman CR , Plescia M , McAfee TA . Oncol Times 2014 36 (12) 64-66 Lung cancer is the leading cause of cancer death and the second most commonly diagnosed cancer (excluding skin cancer) among men and women in the United States. Although lung cancer can be caused by environmental exposures, most efforts to prevent lung cancer emphasize tobacco control because 80%-90% of lung cancers are attributed to cigarette smoking and secondhand smoke. One sentinel health consequence of tobacco use is lung cancer, and one way to measure the impact of tobacco control is by examining trends in lung cancer incidence rates, particularly among younger adults. Changes in lung cancer rates among younger adults likely reflect recent changes in risk exposure. To assess lung cancer incidence and trends among men and women by age group, CDC used data from the National Program of Cancer Registries (NPCR) and the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) program for the period 2005-2009, the most recent data available. During the study period, lung cancer incidence decreased among men in all age groups except <35 years and decreased among women aged 35-44 years and 54-64 years. Lung cancer incidence decreased more rapidly among men than among women and more rapidly among adults aged 35-44 years than among other age groups. To further reduce lung cancer incidence in the United States, proven population-based tobacco prevention and control strategies should receive sustained attention and support. |
Disparities in cancer mortality and incidence among American Indians and Alaska Natives in the United States
White MC , Espey DK , Swan J , Wiggins CL , Eheman C , Kaur JS . Am J Public Health 2014 104 Suppl 3 S377-87 OBJECTIVES: We used improved data on American Indian and Alaska Native (AI/AN) ancestry to provide an updated and comprehensive description of cancer mortality and incidence among AI/AN populations from 1990 to 2009. METHODS: We linked the National Death Index and central cancer registry records independently to the Indian Health Service (IHS) patient registration database to improve identification of AI/AN persons in cancer mortality and incidence data, respectively. Analyses were restricted to non-Hispanic persons residing in Contract Health Service Delivery Area counties in 6 geographic regions of the United States. We compared age-adjusted mortality and incidence rates for AI/AN populations with White populations using rate ratios and mortality-to-incidence ratios. Trends were described using joinpoint analysis. RESULTS: Cancer mortality and incidence rates for AI/AN persons compared with Whites varied by region and type of cancer. Trends in death rates showed that greater progress in cancer control was achieved for White populations compared with AI/AN populations over the last 2 decades. CONCLUSIONS: Spatial variations in mortality and incidence by type of cancer demonstrated both persistent and emerging challenges for cancer control in AI/AN populations. |
Changes in colorectal cancer incidence rates in young and older adults in the United States: what does it tell us about screening
Austin H , Henley SJ , King J , Richardson LC , Eheman C . Cancer Causes Control 2014 25 (2) 191-201 PURPOSE: Colorectal cancer (CRC) incidence rates have increased among young adults and have decreased among older adults. We re-evaluated these trends using more recent data covering about 96 % of the United States population. METHODS: Colorectal cancer incidence rates were abstracted from the National Program of Cancer Registries and the Surveillance Epidemiology and End Results analytic files for diagnosis years 1998-2009. We report rates for young adults (age <50 years) and for older adults (age 50 years or older) by four race/ethnicity groupings. We examined CRC incidence rates by stage at diagnosis, tumor subsite, and state. We calculated the correlation between state-specific CRC incidence and prevalence of colonoscopy reported in the Behavioral Risk Factor Surveillance System. RESULTS: Rectal cancer incidence rates increased from 1998 through 2009 among young non-Hispanic white adults and young blacks. Among older adults, CRC incidence rates decreased among all four race/ethnicity groupings and in all states. The decline was apparent for all stages and for all subsites. States with greater decreases in CRC incidence rates had higher colonoscopy screening rates. CONCLUSION: Rectal cancer is increasing among younger adults, for reasons largely unknown. Among older adults, CRC incidence continues to decrease, probably because of increasing uptake of colonoscopy screening. Decreases in CRC incidence are correlated with increased use of colonoscopy, indicating that CRC may be largely preventable through colonoscopy screening. Efforts to increase screening rates in underserved populations would help reduce health disparities associated with this type of cancer. |
Investigating suspected cancer clusters and responding to community concerns: guidelines from CDC and the Council of State and Territorial Epidemiologists
Abrams B , Anderson H , Blackmore C , Bove FJ , Condon SK , Eheman CR , Fagliano J , Haynes LB , Lewis LS , Major J , McGeehin MA , Simms E , Sircar K , Soler J , Stanbury M , Watkins SM , Wartenberg D . MMWR Recomm Rep 2013 62 1-24 This report augments guidelines published in 1990 for investigating clusters of health events (CDC. Guidelines for investigating clusters of health events. MMWR 1990;39[No. RR-11]). The 1990 Guidelines considered any noninfectious disease cluster, injuries, birth defects, and previously unrecognized syndromes or illnesses. These new guidelines focus on cancer clusters. State and local health departments can use these guidelines to develop a systematic approach to responding to community concerns regarding cancer clusters. The guidelines are intended to apply to situations in which a health department responds to an inquiry about a suspected cancer cluster in a residential or community setting only. Occupational or medical treatment-related clusters are not included in this report. Since 1990, many improvements have occurred in data resources, investigative techniques, and analytic/statistical methods, and much has been learned from both large- and small-scale cancer cluster investigations. These improvements and lessons have informed these updated guidelines. These guidelines utilize a four-step approach (initial response, assessment, major feasibility study, and etiologic investigation) as a tool for managing a reported cluster. Even if a cancer cluster is identified, there is no guarantee that a common cause or an environmental contaminant will be implicated. Identification of a common cause or an implicated contaminant might be an expected outcome for the concerned community. Therefore, during all parts of an inquiry, responders should be transparent, communicate clearly, and explain their decisions to the community. |
Regional variations in esophageal cancer rates by census region in the United States, 1999-2008
Drahos J , Wu M , Anderson WF , Trivers KF , King J , Rosenberg PS , Eheman C , Cook MB . PLoS One 2013 8 (7) e67913 BACKGROUND: Assessment of cancer incidence trends within the U.S. have mostly relied upon Surveillance, Epidemiology, and End Results (SEER) data, with implicit inference that such is representative of the general population. However, many cancer policy decisions are based at a more granular level. To help inform such, analyses of regional cancer incidence data are needed. Leveraging the unique resource of National Program of Cancer Registries (NPCR)-SEER, we assessed whether regional rates and trends of esophageal cancer significantly deviated from national estimates. METHODS: From NPCR-SEER, we extracted cancer case counts and populations for whites aged 45-84 years by calendar year, histology, sex, and census region for the period 1999-2008. We calculated age-standardized incidence rates (ASRs), annual percent changes (APCs), and male-to-female incidence rate ratios (IRRs). RESULTS: This analysis included 65,823 esophageal adenocarcinomas and 27,094 esophageal squamous cell carcinomas diagnosed during 778 million person-years. We observed significant geographic variability in incidence rates and trends, especially for esophageal adenocarcinomas in males: ASRs were highest in the Northeast (17.7 per 100,000) and Midwest (18.1). Both were significantly higher than the national estimate (16.0). In addition, the Northeast APC was 62% higher than the national estimate (3.19% vs. 1.97%). Lastly, IRRs remained fairly constant across calendar time, despite changes in incidence rates. CONCLUSION: Significant regional variations in esophageal cancer incidence trends exist in the U.S. Stable IRRs may indicate the predominant factors affecting incidence rates are similar in men and women. |
Mesothelioma incidence in 50 states and the District of Columbia, United States, 2003-2008
Henley SJ , Larson TC , Wu M , Antao VC , Lewis M , Pinheiro GA , Eheman C . Int J Occup Environ Health 2013 19 (1) 1-10 BACKGROUND: The decline in asbestos use in the United States may impact mesothelioma incidence. OBJECTIVE: This report provides national and state-specific estimates of mesothelioma incidence in the United States using cancer surveillance data for the entire US population. METHODS: Data from the National Program for Cancer Registries and the Surveillance, Epidemiology, and End Results program were used to calculate incidence rates and annual percent change. RESULTS: During 2003-2008, an average of 1.05 mesothelioma cases per 100,000 persons were diagnosed annually in the United States; the number of cases diagnosed each year remained level, whereas rates decreased among men and were stable among women. CONCLUSION: US population-based cancer registry data can be used to determine the burden of mesothelioma and track its decline. Even 30 years after peak asbestos use in the United States, 3200 mesothelioma cases are diagnosed annually, showing that the US population is still at risk. |
Annual report to the nation on the status of cancer, 1975-2009, featuring the burden and trends in human papillomavirus (HPV)-associated cancers and HPV vaccination coverage levels
Jemal A , Simard EP , Dorell C , Noone AM , Markowitz LE , Kohler B , Eheman C , Saraiya M , Bandi P , Saslow D , Cronin KA , Watson M , Schiffman M , Henley SJ , Schymura MJ , Anderson RN , Yankey D , Edwards BK . J Natl Cancer Inst 2013 105 (3) 175-201 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 annually to provide updates on cancer incidence and death rates and trends in these outcomes for the United States. This year's report includes incidence trends for human papillomavirus (HPV)-associated cancers and HPV vaccination (recommended for adolescents aged 11-12 years). METHODS: Data on cancer incidence were obtained from the CDC, NCI, and NAACCR, and data on mortality were obtained from the CDC. Long- (1975/1992-2009) and short-term (2000-2009) trends in age-standardized incidence and death rates for all cancers combined and for the leading cancers among men and among women were examined by joinpoint analysis. Prevalence of HPV vaccination coverage during 2008 and 2010 and of Papanicolaou (Pap) testing during 2010 were obtained from national surveys. RESULTS: Death rates continued to decline for all cancers combined for men and women of all major racial and ethnic groups and for most major cancer sites; rates for both sexes combined decreased by 1.5% per year from 2000 to 2009. Overall incidence rates decreased in men but stabilized in women. Incidence rates increased for two HPV-associated cancers (oropharynx, anus) and some cancers not associated with HPV (eg, liver, kidney, thyroid). Nationally, 32.0% (95% confidence interval [CI] = 30.3% to 33.6%) of girls aged 13 to 17 years in 2010 had received three doses of the HPV vaccine, and coverage was statistically significantly lower among the uninsured (14.1%, 95% CI = 9.4% to 20.6%) and in some Southern states (eg, 20.0% in Alabama [95% CI = 13.9% to 27.9%] and Mississippi [95% CI = 13.8% to 28.2%]), where cervical cancer rates were highest and recent Pap testing prevalence was the lowest. CONCLUSIONS: The overall trends in declining cancer death rates continue. However, increases in incidence rates for some HPV-associated cancers and low vaccination coverage among adolescents underscore the need for additional prevention efforts for HPV-associated cancers, including efforts to increase vaccination coverage. |
Annual report to the nation on the status of cancer, 1975-2008, featuring cancers associated with excess weight and lack of sufficient physical activity
Eheman C , Henley J , Ballard-Barbash R , Jacobs EJ , Schymura MJ , Noone A-M , Pan L , Anderson RN , Fulton JE , Kohler BA , Jemal A , Ward E , Plescia M , Ries LAG , Edwards BK . Cancer 2012 118 (9) 2338-66 BACKGROUND: Annual updates on cancer occurrence and trends in the United States are provided through collaboration between 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). This year's report highlights the increased cancer risk associated with excess weight (overweight or obesity) and lack of sufficient physical activity (<150 minutes of physical activity per week). METHODS: Data on cancer incidence were obtained from the CDC, NCI, and NAACCR; data on cancer deaths were obtained from the CDC's National Center for Health Statistics. Annual percent changes in incidence and death rates (age-standardized to the 2000 US population) for all cancers combined and for the leading cancers among men and among women were estimated by joinpoint analysis of long-term trends (incidence for 1992-2008 and mortality for 1975-2008) and short-term trends (1999-2008). Information was obtained from national surveys about the proportion of US children, adolescents, and adults who are overweight, obese, insufficiently physically active, or physically inactive. RESULTS: Death rates from all cancers combined decreased from 1999 to 2008, continuing a decline that began in the early 1990s, among men and among women in most racial and ethnic groups. Death rates decreased from 1999 to 2008 for most cancer sites, including the 4 most common cancers (lung, colorectum, breast, and prostate). The incidence of prostate and colorectal cancers also decreased from 1999 to 2008. Lung cancer incidence declined from 1999 to 2008 among men and from 2004 to 2008 among women. Breast cancer incidence decreased from 1999 to 2004 but was stable from 2004 to 2008. Incidence increased for several cancers, including pancreas, kidney, and adenocarcinoma of the esophagus, which are associated with excess weight. CONCLUSIONS: Although improvements are reported in the US cancer burden, excess weight and lack of sufficient physical activity contribute to the increased incidence of many cancers, adversely affect quality of life for cancer survivors, and may worsen prognosis for several cancers. The current report highlights the importance of efforts to promote healthy weight and sufficient physical activity in reducing the cancer burden in the United States. |
Divergent trends for gastric cancer incidence by anatomical subsite in US adults
Camargo MC , Anderson WF , King JB , Correa P , Thomas CC , Rosenberg PS , Eheman CR , Rabkin CS . Gut 2011 60 (12) 1644-9 BACKGROUND AND AIM: Age-specific analyses of non-cardia gastric cancer incidence reveal divergent trends among US whites: rates are declining in individuals aged 40 years and older but rising in younger persons. To investigate this heterogeneity further, incidence trends were evaluated by anatomical subsite. METHODS: Gastric cancer incidence data for 1976-2007 were obtained from the US National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) Program and the US Centers for Disease Control and Prevention's National Program of Cancer Registries (NPCR). Incidence rates and estimated annual percentage change were calculated by age group (25-39, 40-59 and 60-84 years), race/ethnicity and subsite. RESULTS: Based on data from the nine oldest SEER registries (covering approximately 10% of the US population), rates for all non-cardia subsites decreased in whites and blacks, except for corpus cancer, which increased between 1976 and 2007 with estimated annual percentage changes of 1.0% (95% CI 0.1% to 1.9%) for whites and 3.5% (95% CI 1.8% to 5.2%) for blacks. In contrast, rates for all non-cardia subsites including corpus cancer declined among other races. In combined data from NPCR and SEER registries (covering 89% of the US population), corpus cancer significantly increased between 1999 and 2007 among younger and middle-aged whites; in ethnic-specific analyses, rates significantly increased among the same age groups in non-Hispanic whites and were stable among Hispanic whites. Age-specific rates for all subsites declined or were stable in this period among blacks and other races. CONCLUSIONS: Long- and short-term incidence trends for gastric cancers indicate a shifting distribution by anatomical subsite. Corpus cancer may have distinctive aetiology and changing risk factor exposures, warranting further investigation. |
Trends in endometrial cancer incidence rates in the United States, 1999-2006
Duong LM , Wilson RJ , Ajani UA , Singh SD , Eheman CR . J Womens Health (Larchmt) 2011 20 (8) 1157-63 BACKGROUND: Risk factors for endometrial cancer, such as hormone replacement therapy (HRT) and obesity, have changed significantly in the last decade. We investigated trends in endometrial cancer histologic subtypes on a national level during 1999-2006. METHODS: Data covering 88% of the U.S. population were from central cancer registries in the National Program of Cancer Registries (NPCR) and Surveillance, Epidemiology, and End Results (SEER) programs that met high-quality United States Cancer Statistics (USCS) criteria. Our analyses included females with microscopically confirmed invasive uterine cancer (n=257,039). Age-adjusted incidence rates and trends for all invasive uterine cancers and by endometrial cancer histologic subtypes (type I and II) were assessed. RSEULTS: There were 145,922 cases of type I endometrial cancers and 15,591 cases of type II for 1999-2006. We found that type I endometrial cancers have been increasing, whereas type II endometrial cancers and all invasive uterine cancers have been relatively stable throughout the 1999-2006 period. CONCLUSIONS: During the past decade, the overall burden of uterine cancer has been stable, although there have been changes in underlying histologies (e.g., endometrial). Changes in trends for underlying histologies may be masked when reviewing trends irrespective of histologic subtypes. Our findings suggest the need to examine trends of uterine cancer by histologic subtype in order to better understand the burden of endometrial cancer in relation to these subtypes to help women at increased risk for developing more aggressive types of endometrial cancer (e.g., type II). |
Annual report to the nation on the status of cancer, 1975-2006, featuring colorectal cancer trends and impact of interventions (risk factors, screening, and treatment) to reduce future rates

Cancer 2010 116 (3) 544-73 BACKGROUND: The American Cancer Society, the Centers for Disease Control and Prevention (CDC), the National Cancer Institute (NCI), and the North American Association of Central Cancer Registries (NAACCR) collaborate annually to provide updated information regarding cancer occurrence and trends in the United States. This year's report includes trends in colorectal cancer (CRC) incidence and death rates and highlights the use of microsimulation modeling as a tool for interpreting past trends and projecting future trends to assist in cancer control planning and policy decisions. METHODS: Information regarding invasive cancers was obtained from the NCI, CDC, and NAACCR; and information on deaths was obtained from the CDC's National Center for Health Statistics. Annual percentage changes in the age-standardized incidence and death rates (based on the year 2000 US population standard) for all cancers combined and for the top 15 cancers were estimated by joinpoint analysis of long-term trends (1975-2006) and for short-term fixed-interval trends (1997-2006). All statistical tests were 2-sided. RESULTS: Both incidence and death rates from all cancers combined significantly declined (P < .05) in the most recent time period for men and women overall and for most racial and ethnic populations. These decreases were driven largely by declines in both incidence and death rates for the 3 most common cancers in men (ie, lung and prostate cancers and CRC) and for 2 of the 3 leading cancers in women (ie, breast cancer and CRC). The long-term trends for lung cancer mortality in women had smaller and smaller increases until 2003, when there was a change to a nonsignificant decline. Microsimulation modeling demonstrates that declines in CRC death rates are consistent with a relatively large contribution from screening and with a smaller but demonstrable impact of risk factor reductions and improved treatments. These declines are projected to continue if risk factor modification, screening, and treatment remain at current rates, but they could be accelerated further with favorable trends in risk factors and higher utilization of screening and optimal treatment. CONCLUSIONS: Although the decrease in overall cancer incidence and death rates is encouraging, rising incidence and mortality for some cancers are of concern. |
Repeat pap testing and colposcopic biopsies in the underserved
Trivers KF , Benard VB , Eheman CR , Royalty JE , Ekwueme DU , Lawson HW . Obstet Gynecol 2009 114 (5) 1049-1056 To quantify repeat Pap testing and colposcopy biopsies among women in the National Breast and Cervical Cancer Early Detection Program between 2003 and 2006 (N=955,494). Rates of repeat Pap testing (two tests within 9 months) and colposcopic biopsies were estimated along with 95% confidence intervals (CIs). Odds ratios and 95% CIs for receipt of colposcopic biopsy compared with repeat Pap testing were estimated from multivariable logistic regression models. Finally, we estimated positive predictive values and 95% CIs of cervical intraepithelial neoplasia (CIN) 2 or worse (CIN 3, carcinoma in situ, invasive cancer) for two strategies: 1) repeat Pap testing followed by colposcopic biopsy and 2) colposcopic biopsy alone. There were 39,583 and 53,880 women with repeat Pap testing and colposcopic biopsy, respectively, from 2003 to 2006. Overall, age-standardized rates of repeat Pap testing and colposcopic biopsies were 37.2 per 1,000 women and 39.3 per 1,000 women, respectively. Younger women, Hispanic women, and African-American women were more likely to receive colposcopic biopsies compared with repeat Pap tests. Positive predictive values of colposcopic biopsy were highest after abnormal Pap test results (27% after a result of atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesion, 70% after a result of high-grade squamous intraepithelial lesion/ squamous cell cancer). Colposcopic biopsies are common among young women after being screened for cervical cancer and, except among those with the most severe Pap test results, may not be efficient in detecting serious disease. These results conflict with current recommendations for less aggressive follow-up for most young women. copyright 2009 by The American College of Obstetricians and Gynecologists. |
Care of long-term cancer survivors: physicians seen by Medicare enrollees surviving longer than 5 years
Pollack LA , Adamache W , Ryerson AB , Eheman CR , Richardson LC . Cancer 2009 115 (22) 5284-95 BACKGROUND: Studies have shown that follow-up care for cancer patients differs by physician specialty, and that coordination between specialists and generalists results in better care. Little is known, however, regarding which specialties of physicians provide care to long-term cancer survivors. METHODS: The authors used Surveillance, Epidemiology, and End Results data from 1992 through 1997 that were linked to 1997-2003 Medicare data to identify persons diagnosed >5 years earlier with bladder, female breast, colorectal, prostate, or uterine cancer. Physician specialties were assigned by combining Medicare data with the American Medical Association Masterfile and the Unique Physician Identification Number Registry. The percentage of long-term survivors who visited physicians of interest was determined by analyzing Medicare outpatient claims submitted 6 to 12 years after initial diagnosis. RESULTS: Over the entire study period, 46% of female breast cancer survivors, 26% of colorectal cancer survivors, and 14% of prostate cancer survivors saw hematologists/oncologists. Radiation oncologists were seen by 11%, 2%, and 14% of breast, colorectal, and prostate cancer survivors, respectively. Survivors also sought care from specialists related to their cancer: 19% of breast cancer survivors had a cancer-coded visit with a surgeon, 26% of colorectal cancer survivors visited a gastroenterologist, and 68% of prostate cancer survivors visited a urologist. The percentage of survivors who visited cancer and cancer-related physicians declined each year. In contrast, nearly 75% of female breast, colorectal, and prostate cancer survivors saw primary care providers, and these percentages did not decrease annually. CONCLUSIONS: The findings of the current study underscore the need to include both primary care providers and cancer-related specialists in education and guidelines regarding cancer survivorship.

Information-seeking styles among cancer patients before and after treatment by demographics and use of information sources
Eheman CR , Berkowitz Z , Lee J , Mohile S , Purnell J , Marie Rodriguez E , Roscoe J , Johnson D , Kirshner J , Morrow G . J Health Commun 2009 14 (5) 487-502 The type and quantity of information needed varies between patients who actively seek information and those who tend to avoid information.We analyzed data from a longitudinal study of adult cancer patients from outpatient clinics for whom information needs and behaviors were assessed by survey before and after treatment. We evaluated the relationships between information-seeking style (active, moderately active, and passive styles) and demographics, cancer type, and health status for the pretreatment and posttreatment periods and overall. The generalized estimating equations (GEE) approach was used to model the log odds of more active to more passive information-seeking preferences taking into consideration both the pretreatment and posttreatment periods. Analyses included 731 case participants, including female breast cancer patients (51%), male genitourinary cancer patients (18%), and lung cancer patients of both sexes (10%). At pretreatment, 17% reported an active information-seeking style, 69% were moderately active, and 14% were passive. During this period, 19% of those with at least some college education reported being very active compared with 14% of those with less education. With adjustment for all other covariates, male genitourinary and lung cancer patients had a higher odds of having a more active information-seeking style in the pretreatment than in the posttreatment period, with an odds of 4.5 (95% confidence interval [CI]: 2.4-8.4) and 5.4 (95% CI: 2.7-10.6), respectively. Controlling for all covariates, breast cancer patients had 1.5 (95% CI: 1.0-2.1) times higher odds of being more active in seeking information than other patients. Public health researchers and clinicians must work together to develop the most effective strategy for meeting the informational needs of these patients before and after treatment. |
