Trends in Endometrial Cancer Incidence Rates in the United States, 1999–2006

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. RESULTS 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).

Association of cutaneous melanoma incidence with area-based socioeconomic indicators-United States, 2004-2006.

BACKGROUND Socioeconomic status (SES) has been associated with melanoma incidence and outcomes. Examination of the relationship between melanoma and SES at the national level in the United States is limited. Expanding knowledge of this association is needed to improve early detection and eliminate disparities. OBJECTIVE We sought to provide a detailed description of cutaneous melanoma incidence and stage of disease in relationship to area-based socioeconomic measures including poverty level, education, income, and unemployment in the United States. METHODS Invasive cutaneous melanoma data reported by 44 population-based central cancer registries for 2004 to 2006 were merged with county-level SES estimates from the US Census Bureau. Age-adjusted incidence rates were calculated by gender, race/ethnicity, poverty, education, income, unemployment, and metro/urban/rural status using software. Poisson multilevel mixed models were fitted, and incidence density ratios were calculated by stage for area-based SES measures, controlling for age, gender, and state random effects. RESULTS Counties with lower poverty, higher education, higher income, and lower unemployment had higher age-adjusted melanoma incidence rates for both early and late stage. In multivariate models, SES effects persisted for early-stage but not late-stage melanoma incidence. LIMITATIONS Individual-level measures of SES were unavailable, and estimates were based on county-level SES measures. CONCLUSION Our findings show that melanoma incidence in the United States is associated with aggregate county-level measures of high SES. Analyses using finer-level SES measures, such as individual or census tract level, are needed to provide more precise estimates of these associations.

Anatomic distribution of malignant melanoma on the non-Hispanic black patient, 1998-2007.

OBJECTIVES To provide a population-based description of the anatomic distribution of melanoma among non-Hispanic black patients and to explore how characteristics of this distribution relate to the etiologies previously reported for both white and black patients. DESIGN Cross-sectional, retrospective. SETTING United States, January 1, 1998, through December 31, 2007. PATIENTS A total of 1439 non-Hispanic black patients with a diagnosis of malignant melanoma. MAIN OUTCOME MEASURES Proportion of melanoma found per anatomic site (head, face, or neck; trunk; upper limb and shoulder; and the lower limb and hip) by patient sex, age, and region of diagnosis. RESULTS The most frequent site of melanoma was the lower limb and hip (848 [58.9%]) and trunk (238 [16.5%]). The youngest median age was presented for diagnoses of the trunk (male: 56 years and females: 48 years). Presentation on the lower limb and hip accounted for most diagnoses in both the northern and southern geographic regions (north: 58.2% and south: 59.7%). CONCLUSIONS By increasing knowledge about the burden of this disease within the black population, our findings can be used to improve the early detection of melanoma by both the patient and the provider.

Cancer Incidence in Appalachia, 2004–2011

Background: Limited literature is available about cancer in the Appalachian Region. This is the only known analysis of all cancers for Appalachia and non-Appalachia covering 100% of the US population. Appalachian cancer incidence and trends were evaluated by state, sex, and race and compared with those found in non-Appalachian regions. Methods: US counties were identified as Appalachian or non-Appalachian. Age-adjusted cancer incidence rates, standard errors, and confidence intervals were calculated using the most recent data from the United States Cancer Statistics for 2004 to 2011. Results: Generally, Appalachia carries a higher cancer burden compared with non-Appalachia, particularly for tobacco-related cancers. For all cancer sites combined, Appalachia has higher rates regardless of sex, race, or region. The Appalachia and non-Appalachia cancer incidence gap has narrowed, with the exception of oral cavity and pharynx, larynx, lung and bronchus, and thyroid cancers. Conclusions: Higher cancer incidence continues in Appalachia and appears at least in part to reflect high tobacco use and potential differences in socioeconomic status, other risk factors, patient health care utilization, or provider practices. It is important to continue to evaluate this population to monitor results from screening and early detection programs, understand behavioral risk factors related to cancer incidence, increase efforts to reduce tobacco use and increase cancer screening, and identify other areas where effective interventions may mediate disparities. Impact: Surveillance and evaluation of special populations provide means to monitor screening and early detection programs, understand behavioral risk factors, and increase efforts to reduce tobacco use to mediate disparities.

Surveillance for cancer incidence and mortality — United States, 2013

This report provides, in tabular and graphic form, official federal statistics on cancer incidence and mortality for 2013 and trends for 1999-2013 as reported by CDC and the National Cancer Institute (NCI). Data in this report come from the United States Cancer Statistics (USCS) system (1), which includes cancer incidence data from population-based cancer registries that participate in CDCs National Program of Cancer Registries (NPCR) and NCIs Surveillance, Epidemiology, and End Results (SEER) program reported as of November 2015 and cancer mortality data from death certificate information reported to state vital statistics offices as of June 2015 and compiled into a national file for the entire United States by CDCs National Center for Health Statistics (NCHS) National Vital Statistics System (NVSS).

Ovarian and Uterine Cancer Incidence and Mortality in American Indian and Alaska Native Women, United States, 1999–2009

OBJECTIVES We examined geographic differences and trends in incidence and mortality of ovarian and uterine cancer in American Indian/Alaska Native (AI/AN) women. METHODS We linked mortality data (1990-2009) and incidence data (1999-2009) to Indian Health Service (IHS) records. Death (and incidence) rates for ovarian and uterine cancer were examined for AI/AN and White women; Hispanics were excluded. Analyses focused on Contract Health Service Delivery Area (CHSDA) counties. RESULTS AI/AN and White women had similar ovarian and uterine cancer death rates. Ovarian and uterine cancer incidence and death rates were higher for AI/ANs residing in CHSDA counties than for all US counties. We also observed geographic differences, regardless of CHSDA residence, in ovarian and uterine cancer incidence and death rates in AI/AN women by IHS region; Pacific Coast and Southern Plains women had higher ovarian cancer death rates and Northern Plains women had higher uterine cancer death rates. CONCLUSIONS Regional differences in the incidence and mortality of ovarian and uterine cancers among AI/AN women in the United States were significant. More research among correctly classified AI/AN women is needed to understand these differences.

Racial and ethnic differences in survival of pediatric patients with brain and central nervous system cancer in the United States

Brain and central nervous system (CNS) cancer is the leading cause of cancer death among children and adolescents in the United States. Data from earlier studies suggested racial and ethnic differences in survival among pediatric patients with brain tumor. This study examined racial/ethnic difference in survival using national data and considered the effects of demographic and clinical factors.

Lung Cancer Among Women in the United States.

November marks Lung Cancer Awareness Month, and reminds us that lung cancer is the leading cause of cancer death among women in the United States. In this brief report, we highlight CDC resources that can be used to examine the most recent data on lung cancer incidence, survival, prevalence, and mortality among women. Using the U.S. Cancer Statistics Data Visualizations tool, we report that in 2015, 104,992 new cases of lung cancer and 70,073 lung cancer deaths were reported among women in the United States. The 5-year relative survival among females diagnosed with lung cancer was 22%, and as of 2015, ∼185,759 women were living with a lung cancer diagnosis. We also describe ways CDC works to collect and disseminate quality cancer surveillance data, prevent initiation of tobacco use, promote cessation, eliminate exposure to secondhand smoke, identify and eliminate disparities, promote lung cancer screening, and help cancer survivors live longer by improving health outcomes.

Racial and ethnic disparities among state Medicaid programs for breast cancer screening

Breast cancer screening by mammography has been shown to reduce breast cancer morbidity and mortality. The use of mammography screening though varies by race, ethnicity, and, sociodemographic characteristics. Medicaid is an important source of insurance in the US for low-income beneficiaries, who are disproportionately members of racial or ethnic minorities, and who are less likely to be screened than women with higher socioeconomic statuses. We used 2006-2008 data from Medicaid claims and enrollment files to assess racial or ethnic and geographic disparities in the use of breast cancer screening among Medicaid-insured women at the state level. There were disparities in the use of mammography among racial or ethnic groups relative to white women, and the use of mammography varied across the 44 states studied. African American and American Indian women were significantly less likely than white women to use mammography in 30% and 39% of the 44 states analyzed, respectively, whereas Hispanic and Asian American women were the minority groups most likely to receive screening compared with white women. There are racial or ethnic disparities in breast cancer screening at the state level, which indicates that analyses conducted by only using national data not stratified by insurance coverage are insufficient to identify vulnerable populations for interventions to increase the use of mammography, as recommended.
