RESUMEN

With this 2016 Summary of Notifiable Noninfectious Conditions and Disease Outbreaks - United States, CDC is publishing official statistics for the occurrence of nationally notifiable noninfectious conditions and disease outbreaks for the second time in the same volume of MMWR as the annual Summary of Notifiable Infectious Diseases and Conditions (1). As was the case for the 2015 Summary of Notifiable Noninfectious Conditions and Disease Outbreaks (2), this joint publication is the result of a request by the Council of State and Territorial Epidemiologists (CSTE) to provide readers with information on all nationally notifiable conditions and disease outbreaks in a single publication.

RESUMEN

BACKGROUND: Expansion of health insurance coverage, and hence clinical preventive services (CPS), provides an opportunity for improvements in the health of adults. The degree to which expansion of health insurance coverage affects the use of CPS is unknown. OBJECTIVE: To assess whether Massachusetts health reform was associated with changes in healthcare access and use of CPS. DESIGN: We used a difference-in-differences framework to examine change in healthcare access and use of CPS among working-aged adults pre-reform (2002-2005) and post-reform (2007-2010) in Massachusetts compared with change in other New England states (ONES). SETTING: Population-based, cross-sectional Behavioral Risk Factor Surveillance System surveys. PARTICIPANTS: A total of 208,831 survey participants aged 18 to 64 years. INTERVENTION: Massachusetts health reform enacted in 2006. MEASUREMENTS: Four healthcare access measures outcomes and five CPS. KEY RESULTS: The proportions of adults who had health insurance coverage, a healthcare provider, no cost barrier to healthcare, an annual routine checkup, and a colorectal cancer screening increased significantly more in Massachusetts than those in the ONES. In Massachusetts, the prevalence of cervical cancer screening in pre-reform and post-reform periods was about the same; however, the ONES had a decrease of -1.6 percentage points (95 % confidence interval [CI] -2.5, -0.7; p <0.001). As a result, the prevalence of cervical cancer screening in Massachusetts was increased relative to the ONES (1.7, 95 % CI 0.2, 3.2; p = 0.02). Cholesterol screening, influenza immunization, and breast cancer screening did not improve more in Massachusetts than in the ONES. LIMITATIONS: Data are self-reported. CONCLUSIONS: Health reform may increase healthcare access and improve use of CPS. However, the effects of health reform on CPS use may vary by type of service and by state.

RESUMEN

Few population-based studies have addressed the role that family history of colorectal cancer (CRC) plays in clinician decision making or patient health choices. The objective of this study was to evaluate the effect of family history of CRC on clinician practice, patient CRC screening, and patient preventive behavior. We analyzed 2008 Oregon Behavioral Risk Factor Surveillance System data to examine associations between family history of CRC and 1) patient-reported clinician recommendations, 2) perceived risk of developing CRC, 3) adoption of preventive and screening behaviors, and 4) CRC risk factors among 1,795 respondents without CRC. A family history of CRC was positively associated with a higher likelihood of respondents reporting that their clinicians discussed colorectal cancer screening (OR, 4.2; 95% CI, 2.4-7.4) and of respondents having colorectal screening within the recommended time period (OR, 2.2; 95% CI, 1.3-3.9). A family history of CRC was also associated with respondents reporting lifestyle changes to prevent CRC (OR, 2.6; 95% CI, 1.7-4.0). A family history of CRC may prompt clinicians to recommend screening and preventive behavior changes and motivate patients to adopt such strategies.

RESUMEN

Genomic copy number alterations (CNA) are common in breast cancer. Identifying characteristic CNAs associated with specific breast cancer subtypes is a critical step in defining potential mechanisms of disease initiation and progression. We used genome-wide array comparative genomic hybridization to identify distinctive CNAs in breast cancer subtypes from 259 young (diagnosed with breast cancer at <55 years) African American (AA) and Caucasian American (CA) women originally enrolled in a larger population-based study. We compared the average frequency of CNAs across the whole genome for each breast tumor subtype and found that estrogen receptor (ER)-negative tumors had a higher average frequency of genome-wide gain (P < 0.0001) and loss (P = 0.02) compared to ER-positive tumors. Triple-negative (TN) tumors had a higher average frequency of genome-wide gain (P < 0.0001) and loss (P = 0.003) than non-TN tumors. No significant difference in CNA frequency was observed between HER2-positive and -negative tumors. We also identified previously unreported recurrent CNAs (frequency >40%) for TN breast tumors at 10q, 11p, 11q, 16q, 20p, and 20q. In addition, we report CNAs that differ in frequency between TN breast tumors of AA and CA women. This is of particular relevance because TN breast cancer is associated with higher mortality and young AA women have higher rates of TN breast tumors compared to CA women. These data support the possibility that higher overall frequency of genomic alteration events as well as specific focal CNAs in TN breast tumors might contribute in part to the poor breast cancer prognosis for young AA women.

RESUMEN

Steroid 5-alpha-reductase type 2 (SRD5a2) is a critical enzyme in androgen metabolism. Two polymorphisms in the SRD5a2 gene, V89L (rs523349) and A49T (rs9282858), have been studied for associations with prostate cancer risk, with conflicting results. The authors conducted a systematic review and meta-analysis (1997-2007) to examine these associations and compared the results with findings from genome-wide association studies of prostate cancer. The meta-analysis included 24 case-control studies (10,088 cases and 10,120 controls for V89L and 4,998 cases and 5,451 controls for A49T). The authors found that prostate cancer was not associated with V89L (L allele vs. V allele: odds ratio = 0.99, 95% confidence interval: 0.94, 1.05) and was probably not associated with A49T (T allele vs. A allele: odds ratio = 1.10, 95% confidence interval: 0.86, 1.40). These results could have been distorted by spectrum-of-disease bias, convenience sampling of cases and controls, genotype misclassification, and/or confounding. Neither V89L nor A49T was included in microarray chips used for published genome-wide association studies. Analysis of well-designed population-based studies with pathway-based arrays containing common genetic variants could be useful for identifying genetic factors in prostate cancer.

RESUMEN

OBJECTIVE: To examine the extent to which the only national organized screening program in the US, the National Breast and Cervical Cancer Early Detection Program (NBCCEDP), has helped to meet the cervical cancer screening needs of underserved women. METHODS: Low-income, uninsured women 18-64 years of age are eligible for free cervical cancer screening services through NBCCEDP. We used data from the US Census Bureau to estimate the number of eligible women, based on insurance status and income. The estimates were adjusted for hysterectomy status using the National Health Interview Survey and the Behavioral Risk Factor Surveillance System. We used administrative data from NBCCEDP to obtain the number of women receiving NBCCEDP-funded Papanicolaou (Pap) tests. We then calculated the percentage of NBCCEDP-eligible women who received free cervical cancer screening through NBCCEDP. We also used the NHIS to calculate the percentage of NBCCEDP-eligible women screened nationally and the percentage unscreened. RESULTS: In 2004-2006, nearly 9% (775,312 of 8.9 million) of NBCCEDP-eligible women, received NBCCEDP-funded Pap test. Rates varied substantially by age groups, race, and ethnicity. NBCCEDP-eligible women 40-64 years of age had a higher screening rate (22.6%) than eligible women 18-39 years of age (2.3%). Non-Hispanic women had a higher screening rate (9.3%) than Hispanic women (7.3%). Among non-Hispanics, the screening rate was highest among American Indian and Alaska Native (AIAN) women (36.1%) and lowest among women of different race combinations (4.6%), The percentage of eligible women screened in each state ranged from 2.0 to 38.4%. CONCLUSIONS: Although NBCCEDP provided cervical cancer screening services to 775,312 low-income, uninsured women, this number represented a small percentage of those eligible. In 2005, more than 34% of NBCCEDP-eligible women (3.1 million women) did not receive recommended Pap tests from either NBCCEDP or other sources.

RESUMEN

Numerous genomic tests continue to emerge as potential tools in the diagnosis, treatment, prognosis, and prevention for a wide variety of common human diseases. To date, most of these tests have "insufficient evidence" of clinical validity and utility for their use in clinical practice. Explicit and quantitative tools can be used in the evaluation of direct and indirect evidence on the utility of genomic tests. As suggested in an article in this month's issue by Veenstra et al., a recommendation matrix can be developed based on the amount of certainty of the evidence and the assessment of the risk-benefit profile. To supplement the current binary (up or down) evidence-based recommendation for use, it is worthwhile to explore all available data to develop a three-tier evidence-based recommendation classification of genomic tests ("use in practice," "promote informed decision-making," and "discourage use"). Promoting informed decision making may be a valuable recommendation for tests for which there is sufficient information on analytic and clinical validity and for which the risk/benefit analysis on clinical utility is promising but not definitive. This approach could provide interim guidance for clinical practice, while rigorous outcomes research is conducted to assess the impact of such tests on patients, families, and population health outcomes.

RESUMEN

BACKGROUND: Breast cancers with a triple negative tumor (TNT) subtype (as defined by lacking protein expression of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2)) preclude the use of available targeted therapies and may contribute to poor outcome and to the historically poorest survival observed among African-American (AA) women. This study examines association of the ER/PR/HER2 subtypes with race and breast cancer survival. METHODS: Breast tumors from a population-based cohort of 116 AA and 360 white Atlanta women aged 20-54, diagnosed from 1990 to 1992 were centrally reviewed and tested by immunohistochemistry. Multivariate survival analyses within subtypes (TNT, ER-PR-HER2+, ER+/PR+HER2+, ER+/PR+HER2-) were conducted using weighted Cox regression and included socio-demographic, prognostic, and treatment factors. RESULTS: TNTs were more prevalent among young women and particularly among AA women (Odds Ratio [OR] = 1.9, 95% Confidence Interval [CI] 1.2-2.9), adjusting for age, stage, grade, and poverty index. Overall mortality was higher for AA women (Hazard Ratio [HR] = 1.9, 95% CI, 1.5-2.5) and differed by subtypes (P < 0.001). Within the TNT subtype, racial differences in survival persisted, after additional adjustment for treatment and comorbidities (HR = 2.0, 95% CI 1.0-3.7). TNTs were uniquely associated with high expression of p16, p53, and Cyclin E; and low Bcl-2 and Cyclin D1 expression. CONCLUSIONS: The high prevalence of TNTs among younger women and particularly younger AA women, along with unique protein expression patterns and poorer survival, suggests varying gene-environment etiologies with respect to age and race/ethnicity and a need for effective therapies.

RESUMEN

OBJECTIVE: Predictors of intrinsic breast cancer subtypes, including the triple-negative (TN) subtype, are largely unknown. We evaluated whether anthropometrics, demographics, and reproductive history were associated with distinct breast cancer subtypes. METHODS: Invasive breast tumors from a population-based case-control study of 476 (116 black and 360 white) Atlanta women aged 20-54, diagnosed between 1990 and 1992, were centrally reviewed and immunohistochemically analyzed for estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2); then grouped [TN (ER-PR-HER2-); ER-PR-HER2+; ER/PR+HER2+; ER/PR+HER2- (case-only reference group)]. Data were from interviews and anthropometric measurements; adjusted odds ratios (OR) and 95% confidence intervals (CI) were estimated using logistic regression, including both case-only and case-control comparisons. RESULTS: From the case-only analyses and compared with the ER/PR+HER2- subtype, women with TN tumors were more likely to be obese than normal/underweight [OR = 1.89 (95% CI = 1.22, 2.92)]. Regardless of HER2 status, ER-PR- tumors were associated with black race, young age at first birth, having a recent birth, and being overweight. CONCLUSIONS: Distinct breast cancer subtypes have unique sociodemographic, anthropometric and reproductive characteristics and possibly different pathways for development.

RESUMEN

The increasing availability of personal genomic tests has led to discussions about the validity and utility of such tests and the balance of benefits and harms. A multidisciplinary workshop was convened by the National Institutes of Health and the Centers for Disease Control and Prevention to review the scientific foundation for using personal genomics in risk assessment and disease prevention and to develop recommendations for targeted research. The clinical validity and utility of personal genomics is a moving target with rapidly developing discoveries but little translation research to close the gap between discoveries and health impact. Workshop participants made recommendations in five domains: (1) developing and applying scientific standards for assessing personal genomic tests; (2) developing and applying a multidisciplinary research agenda, including observational studies and clinical trials to fill knowledge gaps in clinical validity and utility; (3) enhancing credible knowledge synthesis and information dissemination to clinicians and consumers; (4) linking scientific findings to evidence-based recommendations for use of personal genomics; and (5) assessing how the concept of personal utility can affect health benefits, costs, and risks by developing appropriate metrics for evaluation. To fulfill the promise of personal genomics, a rigorous multidisciplinary research agenda is needed.

RESUMEN

BACKGROUND: Colorectal cancer (CRC) screening rates are low, and racial, ethnic, and economic disparities have been reported. Whether disparities in CRC screening have decreased over time is unknown. This study aimed to determine whether progress was made between 2000 and 2005 in reducing CRC screening disparities by race, ethnicity, income, and insurance status. METHODS: Age-adjusted percentages of participants aged 50-64 who reported CRC screening (home fecal occult blood test in the past year or endoscopy in the past 10 years) were estimated from the 2000 (n=6,020 participants) and 2005 (n=6,706) cancer control supplements of the National Health Interview Survey, with analysis in 2007. RESULTS: Screening rates did not increase between 2000 and 2005 for Hispanic women or uninsured women. Only for high-income participants did screening exceed 50%. For both men and women, the uninsured had the lowest levels of screening (19.1% and 19.3%, respectively, in 2005), and the greatest disparities were observed among groups defined by health insurance status. For women, disparities by ethnicity, income, and insurance status increased over time, whereas among men, disparities in 2005 were similar to those in 2000. For Hispanic women, growing disparities were present at all income and insurance levels and persisted after additional adjustment. CONCLUSIONS: No progress was made in reducing most CRC screening disparities between 2000 and 2005. Methods are needed to increase CRC screening among everyone, but in particular Hispanic women and uninsured men and women.

RESUMEN

Most major medical organizations recommend routine screening for breast, cervical, and colorectal cancers. Screening can lead to early detection of these cancers, resulting in reduced mortality. Yet not all people who should be screened are screened, either regularly or, in some cases, ever. This report presents the results of systematic reviews of effectiveness, applicability, economic efficiency, barriers to implementation, and other harms or benefits of interventions designed to increase screening for breast, cervical, and colorectal cancers by increasing community access to these services. Evidence from these reviews indicates that screening for breast cancer (by mammography) has been increased effectively by reducing structural barriers and by reducing out-of pocket client costs, and that screening for colorectal cancer (by fecal occult blood test) has been increased effectively by reducing structural barriers. Additional research is needed to determine whether screening for cervical cancer (by Pap test) can be increased by reducing structural barriers and by reducing out-of-pocket costs, whether screening for colorectal cancer (fecal occult blood test) can be increased by reducing out-of-pocket costs, and whether these interventions are effective in increasing the use of other colorectal cancer screening procedures (i.e., flexible sigmoidoscopy, colonoscopy, double contrast barium enema). Specific areas for further research are also suggested in this report.

RESUMEN

Most major medical organizations recommend routine screening for breast, cervical, and colorectal cancers. Screening can lead to early detection of these cancers, resulting in reduced mortality. Yet not all people who should be screened are screened, either regularly or, in some cases, ever. This report presents results of systematic reviews of effectiveness, applicability, economic efficiency, barriers to implementation, and other harms or benefits of two provider-directed intervention approaches to increase screening for breast, cervical, and colorectal cancers. These approaches, provider assessment and feedback, and provider incentives encourage providers to deliver screening services at appropriate intervals. Evidence in these reviews indicates that provider assessment and feedback interventions can effectively increase screening by mammography, Pap test, and fecal occult blood test. Health plans, healthcare systems, and cancer control coalitions should consider such evidence-based findings when implementing interventions to increase screening use. Evidence was insufficient to determine the effectiveness of provider incentives in increasing use of any of these tests. Specific areas for further research are suggested in this report, including the need for additional research to determine whether provider incentives are effective in increasing use of any of these screening tests, and whether assessment and feedback interventions are effective in increasing other tests for colorectal cancer (i.e., flexible sigmoidoscopy, colonoscopy, or double-contrast barium enema).

RESUMEN

Most major medical organizations recommend routine screening for breast, cervical, and colorectal cancers. Screening can lead to early detection of these cancers, resulting in reduced mortality. Yet not all people who should be screened are screened, either regularly or, in some cases, ever. This report presents the results of systematic reviews of effectiveness, applicability, economic efficiency, barriers to implementation, and other harms or benefits of interventions designed to increase screening for breast, cervical, and colorectal cancers by increasing community demand for these services. Evidence from these reviews indicates that screening for breast cancer (mammography) and cervical cancer (Pap test) has been effectively increased by use of client reminders, small media, and one-on-one education. Screening for colorectal cancer by fecal occult blood test has been increased effectively by use of client reminders and small media. Additional research is needed to determine whether client incentives, group education, and mass media are effective in increasing use of any of the three screening tests; whether one-on-one education increases screening for colorectal cancer; and whether any demand-enhancing interventions are effective in increasing the use of other colorectal cancer screening procedures (i.e., flexible sigmoidoscopy, colonoscopy, double contrast barium enema). Specific areas for further research are also suggested in this report.

RESUMEN

OBJECTIVE: To assess effects on breast cancer risk of exposure to both oral contraceptives and menopausal hormones, an increasingly common exposure. DESIGN: A case-control study of breast cancer among women under the age of 55 years in Atlanta, GA involving 1,031 cases and 919 population controls was conducted. RESULTS: Ever use of oral contraceptives was associated with a relative risk of 1.1 (95% 0.9-1.4), whereas the relative risk for hormone replacement therapy was 0.9 (95% CI 0.7-1.2). Seventeen percent of the cases versus 19% of the population controls reported exposure to both agents, resulting in a relative risk of 1.0 (95% CI 0.7-1.4) relative to those unexposed to either preparation. Although there was little variation in risk associated with joint effects by either age or race, there were statistically nonsignificant elevations in risk for this exposure among women who had experienced a natural menopause (relative risk = 2.0, 95% CI 0.7-5.6), were relatively thin (relative risk = 1.5, 0.8-3.0), or who had a first degree relative with breast cancer (relative risk = 2.0, 0.6-7.0). When joint effects of longer term use of both agents were considered, subjects who reported use of oral contraceptives for 10 or more years and hormone replacement for 3 or more years had a relative risk of 3.2 (95% CI 1.4-7.4) compared with nonusers of either preparation. CONCLUSIONS: Although our results must be cautiously interpreted given small numbers within subgroups, they raise concern and emphasize the need for further evaluation on breast cancer risk of the increasingly common exposure to both oral contraceptives and hormone replacement therapy.

RESUMEN

Recent oral contraceptive (OC) use is associated with modestly higher breast cancer incidence among younger women, but its impact on survival is unclear. This study examined the relationship between OC use before breast cancer diagnosis and survival. A population-based sample of 1,264 women aged 20 to 54 years with a first primary invasive breast cancer during 1990 to 1992 were followed up for 8 to 10 years. OC and covariate data were obtained by interviews conducted shortly after diagnosis and from medial records. All-cause mortality was ascertained through the National Death Index (n = 292 deaths). Age- and income-adjusted hazard ratios (HR) and 95% confidence intervals (95% CI) were estimated by Cox regression methods. All-cause mortality was not associated with ever use of OCs or duration of use. Compared with nonusers, mortality estimates were elevated among women who were using OCs at diagnosis or stopped use in the previous year (HR, 1.57; 95% CI, 0.95-2.61). The HR for use of high-dose estrogen pills within 5 years before diagnosis was double that of nonusers (HR, 2.39; 95% CI, 1.29-4.41) or, if the most recent pill included the progestin levonorgestrel, compared with nonusers (HR, 2.01; 95% CI, 1.03-3.91). Because subgroup estimates were based on small numbers of OC users, these results should be cautiously interpreted. Overall, most aspects of OC use did not seem to influence survival, although there is limited evidence that OC use just before diagnosis, particularly use of some pill types, may negatively impact survival in breast cancer patients aged 20 to 54 years.

RESUMEN

Among postmenopausal women, obesity is linked to increased risk of breast cancer and poorer subsequent survival. For premenopausal women, obesity may reduce incidence, but less is known about its effect on prognosis, particularly for abdominal obesity. This study investigated whether general or abdominal obesity at diagnosis influenced survival in a cohort of young women with breast cancer. A population-based follow-up study was conducted among 1,254 women ages 20 to 54 who were diagnosed with invasive breast cancer between 1990 and 1992 in Atlanta or New Jersey. Women were interviewed within several months of diagnosis and asked about their weight and height at age 20 and in the year before diagnosis. Study personnel did anthropometric measures at the interview. With 8 to 10 years of follow-up, all-cause mortality status was determined using the National Death Index (n = 290 deaths). Increased mortality was observed for women who were obese [body mass index (BMI), > or =30] at the time of interview compared with women of ideal weight [BMI, 18.5-24.9; stage- and income-adjusted hazard ratio (HR), 1.48; 95% confidence interval (95% CI), 1.09-2.01]. A similar result was seen for the highest versus lowest quartile of waist-to-hip ratio (HR, 1.52; 95% CI, 1.05-2.19). Strong associations with mortality were found for women who were obese at age 20 (HR, 2.49; 95% CI, 1.15-5.37) or who were overweight/obese (BMI, > or =25) at both age 20 and the time of interview (HR, 2.22; 95% CI, 1.45-3.40). This study provides evidence that breast cancer survival is reduced among younger women with general or abdominal obesity.
