Objectives. To evaluate the association between living alone and suicide and how it varies across sociodemographic characteristics. Methods. A nationally representative sample of adults from the 2008 American Community Survey (n = 3 310 000) was followed through 2019 for mortality. Cox models estimated hazard ratios of suicide across living arrangements (living alone or with others) at the time of the survey. Total and sociodemographically stratified models compared hazards of suicide of people living alone to people living with others. Results. Annual suicide rates per 100 000 person-years were 23.0 among adults living alone and 13.2 among adults living with others. The age-, sex-, and race/ethnicity-adjusted hazard ratio of suicide for living alone was 1.75 (95% confidence interval = 1.64, 1.87). Adjusted hazards of suicide associated with living alone varied across sociodemographic groups and were highest for adults with 4-year college degrees and annual incomes greater than $125 000 and lowest for Black individuals. Conclusions. Living alone is a risk marker for suicide with the strongest associations for adults with the highest levels of income and education. Because these associations were not controlled for psychiatric disorders, they should be interpreted as noncausal.

Background: Area-level measures are often used to approximate socioeconomic status (SES) when individual-level data are not available. However, no national studies have examined the validity of these measures in approximating individual-level SES. Methods: Data came from ~ 3,471,000 participants in the Mortality Disparities in American Communities study, which links data from 2008 American Community Survey to National Death Index (through 2015). We calculated correlations, specificity, sensitivity, and odds ratios to summarize the concordance between individual-, census tract-, and county-level SES indicators (e.g., household income, college degree, unemployment). We estimated the association between each SES measure and mortality to illustrate the implications of misclassification for estimates of the SES-mortality association. Results: Participants with high individual-level SES were more likely than other participants to live in high-SES areas. For example, individuals with high household incomes were more likely to live in census tracts (r = 0.232; odds ratio [OR] = 2.284) or counties (r = 0.157; OR = 1.325) whose median household income was above the US median. Across indicators, mortality was higher among low-SES groups (all p <.0001). Compared to county-level, census tract-level measures more closely approximated individual-level associations with mortality. Conclusions: Moderate agreement emerged among binary indicators of SES across individual, census tract, and county levels, with increased precision for census tract compared to county measures when approximating individual-level values. When area level measures were used as proxies for individual SES, the SES-mortality associations were systematically underestimated. Studies using area-level SES proxies should use caution when selecting, analyzing, and interpreting associations with health outcomes. [ABSTRACT FROM AUTHOR]

HEPATOCELLULAR carcinoma ,ETIOLOGY of diseases - Abstract
In the United States, hepatocellular carcinoma (HCC) survival varies with tumor characteristics, patient comorbidities, and treatment. The effect of HCC etiology on survival is less clearly defined. The relationship between HCC etiology and mortality was examined using Surveillance, Epidemiology, and End Results–Medicare data. In a cohort of 11,522 HCC cases diagnosed from 2000 through 2014, etiologies were identified from Medicare data, including metabolic disorders (32.9%), hepatitis C virus (8.2%), alcohol (4.7%), hepatitis B virus (HBV, 2.1%), rare etiologies (0.9%), multiple etiologies (26.7%), and unknown etiology (24.4%). After adjusting for demographics, tumor characteristics, comorbidities and treatment, hazard ratios (HRs) and survival curves by HCC etiology were estimated using Cox proportional hazard models. Compared with HBV‐related HCC cases, higher mortality was observed for those with alcohol‐related HCC (HR 1.49; 95% confidence interval [95% CI] 1.25‐1.77), metabolic disorder–related HCC (HR 1.25; 95% CI 1.07‐1.47), and multiple etiology‐related HCC (HR 1.25; 95% CI 1.07‐1.46), but was not statistically significant for hepatitis C virus–related, rare disorder–related, and HCC of unknown etiology. For all HCC etiologies, there was short median survival ranging from 6.1 months for alcohol to 10.3 months for HBV. Conclusion: More favorable survival was seen with HBV‐related HCC. To the extent that HCC screening is more common among persons with HBV infection compared to those with other etiologic risk factors, population‐based HCC screening, applied evenly to persons across all HCC etiology categories, could shift HCC diagnosis to earlier stages, when cases with good clinical status are more amenable to curative therapy.

Background and Aim: The incidence of hepatocellular carcinoma (HCC) has risen considerably in the US since 1980. The main causes include metabolic disorders (NAFLD, diabetes, obesity, metabolic syndrome), alcohol‐related disease (ALD) and hepatitis C and B virus infections (HCV, HBV). Etiology‐specific HCC incidence rates by detailed race‐ethnicity are needed to improve HCC control and prevention efforts. Methods: All HCC cases diagnosed in Florida during 2014‐2015 were linked to statewide hospital discharge data to determine etiology. Age‐specific and age‐adjusted rates were used to assess the intersection between etiology and detailed racial‐ethnicities, including White, African American, Afro‐Caribbean, Asian, Cuban, Puerto Rican and Continental Hispanic (Mexican, South and Central American). Results: Of 3666 HCC cases, 2594 matched with discharge data. HCV was the leading cause of HCC among men and women (50% and 43% respectively), followed by metabolic disorders (25% and 37%) and ALD (16% and 9%). Puerto Rican and African American men had the highest HCV‐HCC rates, 7.9 and 6.3 per 100 000 respectively. Age‐specific rates for HCV‐HCC peaked among baby boomers (those born in 1945‐1965). Metabolic‐HCC rates were highest among populations above age 70 and among Continental Hispanics. Afro‐Caribbean men had high rates of HBV‐HCC, whereas Puerto Rican men had high ALD‐HCC. Conclusions: HCC etiology is associated with specific race/ethnicity. While HCV‐related HCC rates are projected to decrease soon, HCC will continue to affect Hispanics disproportionately, based on higher rates of metabolic‐HCC (and ALD‐HCC) among Continental Hispanics, who demographically represent 80% of all US Hispanics. Multifaceted approaches for HCC control and prevention are needed. [ABSTRACT FROM AUTHOR]

- Abstract
Background: The total QT interval comprises both ventricular depolarization and repolarization currents. Understanding how HIV serostatus and other risk factors influence specific QT interval subcomponents could improve our mechanistic understanding of arrhythmias.Methods: Twelve-lead electrocardiograms (ECGs) were acquired in 774 HIV-infected (HIV+) and 652 HIV-uninfected (HIV-) men from the Multicenter AIDS Cohort Study. Individual QT subcomponent intervals were analyzed: R-onset to R-peak, R-peak to R-end, JT segment, T-onset to T-peak, and T-peak to T-end. Using multivariable linear regressions, we investigated associations between HIV serostatus and covariates, including serum concentrations of inflammatory biomarkers such as interleukin-6 (IL-6), and each QT subcomponent.Results: After adjustment for demographics and risk factors, HIV+ versus HIV- men differed only in repolarization phase durations with longer T-onset to T-peak by 2.3 ms (95% CI 0-4.5, p < .05) and T-peak to T-end by 1.6 ms (95% CI 0.3-2.9, p < .05). Adjusting for inflammation attenuated the strength and significance of the relationship between HIV serostatus and repolarization. The highest tertile of IL-6 was associated with a 7.3 ms (95% CI 3.2-11.5, p < .01) longer T-onset to T-peak. Age, race, body mass index, alcohol use, and left ventricular hypertrophy were each associated with up to 2.2-12.5 ms longer T-wave subcomponents.Conclusions: HIV seropositivity, in combination with additional risk factors including increased systemic inflammation, is associated with longer T-wave subcomponents. These findings could suggest mechanisms by which the ventricular repolarization phase is lengthened and thereby contribute to increased arrhythmic risk in men living with HIV.

Background: Previous research suggests that Adventists, who often follow vegetarian diets, live longer and have lower risks for many cancers than others, but there are no national data and little published comparative data for black subjects.Methods: This study compared all-cause mortality and cancer incidence between the nationally inclusive Adventist Health Study 2 (AHS-2) and nonsmokers in US Census populations: the National Longitudinal Mortality Study (NLMS) and its Surveillance, Epidemiology, and End Results substudy. Analyses used proportional hazards regression adjusting for age, sex, race, cigarette smoking history, and education.Results: All-cause mortality and all-cancer incidence in the black AHS-2 population were significantly lower than those for the black NLMS populations (hazard ratio [HR] for mortality, 0.64; 95% confidence interval [CI], 0.59-0.69; HR for incidence, 0.78; 95% CI, 0.68-0.88). When races were combined, estimated all-cause mortality was also significantly lower in the AHS-2 population at the age of 65 years (HR, 0.67; 95% CI, 0.64-0.69) and at the age of 85 years (HR, 0.78; 95% CI, 0.75-0.81), as was cancer mortality; this was also true for the rate of all incident cancers combined (HR, 0.70; 95% CI, 0.67-0.74) and the rates of breast, colorectal, and lung cancers. Survival curves confirmed the mortality results and showed that among males, AHS-2 blacks survived longer than white US subjects.Conclusions: Substantially lower rates of all-cause mortality and cancer incidence among Adventists have implications for the effects of lifestyle and perhaps particularly diet on the etiology of these health problems. Trends similar to those seen in the combined population are also found in comparisons of black AHS-2 and NLMS subjects. [ABSTRACT FROM AUTHOR]- Published

Background: Understanding relationships between individual-level demographic, socioeconomic status (SES) and U.S. opioid fatalities can inform interventions in response to this crisis. Methods: The Mortality Disparities in American Community Study (MDAC) links nearly 4 million 2008 American Community Survey responses to the 2008–2015 National Death Index. Univariate and multivariable models were used to estimate opioid overdose fatality hazard ratios (HR) and 95% confidence intervals (CI). Results: Opioid overdose was an overrepresented cause of death among people 10 to 59 years of age. In multivariable analysis, compared to Hispanics, Whites and American Indians/Alaska Natives had elevated risk (HR = 2.52, CI:2.21–2.88) and (HR = 1.88, CI:1.35–2.62), respectively. Compared to women, men were at-risk (HR = 1.61, CI:1.50–1.72). People who were disabled were at higher risk than those who were not (HR = 2.80, CI:2.59–3.03). Risk was higher among widowed than married (HR = 2.44, CI:2.03–2.95) and unemployed than employed individuals (HR = 2.46, CI:2.17–2.79). Compared to adults with graduate degrees, those with high school only were at-risk (HR = 2.48, CI:2.00–3.06). Citizens were more likely than noncitizens to die from this cause (HR = 4.62, CI:3.48–6.14). Compared to people who owned homes with mortgages, those who rented had higher HRs (HR = 1.36, CI:1.25–1.48). Non-rural residents had higher risk than rural residents (HR = 1.46, CI:1.34, 1.59). Compared to respective referent groups, people without health insurance (HR = 1.30, CI:1.20–1.41) and people who were incarcerated were more likely to die from opioid overdoses (HR = 2.70, CI:1.91–3.81). Compared to people living in households at least five-times above the poverty line, people who lived in poverty were more likely to die from this cause (HR = 1.36, CI:1.20–1.54). Compared to people living in West North Central states, HRs were highest among those in South Atlantic (HR = 1.29, CI:1.11, 1.50) and Mountain states (HR = 1.58, CI:1.33, 1.88). Discussion: Opioid fatality was associated with indicators of low SES. The findings may help to target prevention, treatment and rehabilitation efforts to vulnerable groups. [ABSTRACT FROM AUTHOR]

Purpose: To learn whether reported associations between major psychosocial stressors and lung cancer are independent of smoking history. Methods: Subjects were at least 25 years old and without lung cancer at enrollment in the United States Census Bureau’s National Longitudinal Mortality Survey in 1995–2008. Follow-up via Surveillance Epidemiology and End Results and National Death Index continued until lung cancer diagnosis, death, or December 2011. Involuntary unemployment, widowhood, and divorce, stratified by sex, were tested for association with subsequent lung cancer using proportional hazards regression for competing risks. Smoking status, years smoked, cigarettes per day, and years since quitting were imputed when missing. Results: At enrollment, subjects (n = 100,733, 47.4% male, age 49.1(±15.8) years) included 17.6% current smokers, 23.5% former smokers. Of men and women, respectively, 11.3% and 15.0% were divorced/separated, 2.9% and 11.8% were widowed, and 2.9% and 2.3% were involuntarily unemployed. Ultimately, 667 subjects developed lung cancer; another 10,071 died without lung cancer. Adjusted for age, education, and ancestry, lung cancer was associated with unemployment, widowhood, and divorce/separation in men but not women. Further adjusted for years smoked, cigarettes per day, and years since quitting, none of these associations was significant in either sex. Conclusions: Once smoking is accounted for, psychosocial stressors in adulthood do not independently promote lung cancer. Given their increased smoking behavior, persons experiencing stressors should be referred to effective alternatives to smoking and to support for smoking cessation. [ABSTRACT FROM AUTHOR]

Background: For many childhood cancers, survival is lower among non-Hispanic blacks and Hispanics in comparison with non-Hispanic whites, and this may be attributed to underlying socioeconomic factors. However, prior childhood cancer survival studies have not formally tested for mediation by socioeconomic status (SES). This study applied mediation methods to quantify the role of SES in racial/ethnic differences in childhood cancer survival.Methods: This study used population-based cancer survival data from the Surveillance, Epidemiology, and End Results 18 database for black, white, and Hispanic children who had been diagnosed at the ages of 0 to 19 years in 2000-2011 (n = 31,866). Black-white and Hispanic-white mortality hazard ratios and 95% confidence intervals, adjusted for age, sex, and stage at diagnosis, were estimated. The inverse odds weighting method was used to test for mediation by SES, which was measured with a validated census-tract composite index.Results: Whites had a significant survival advantage over blacks and Hispanics for several childhood cancers. SES significantly mediated the race/ethnicity-survival association for acute lymphoblastic leukemia, acute myeloid leukemia, neuroblastoma, and non-Hodgkin lymphoma; SES reduced the original association between race/ethnicity and survival by 44%, 28%, 49%, and 34%, respectively, for blacks versus whites and by 31%, 73%, 48%, and 28%, respectively, for Hispanics versus whites ((log hazard ratio total effect - log hazard ratio direct effect)/log hazard ratio total effect).Conclusions: SES significantly mediates racial/ethnic childhood cancer survival disparities for several cancers. However, the proportion of the total race/ethnicity-survival association explained by SES varies between black-white and Hispanic-white comparisons for some cancers, and this suggests that mediation by other factors differs across groups.

Abstract: Racial disparities in cancer mortality still exist despite improvements in treatment strategies leading to improved survival for many cancer types. In this study, we described race/ethnic differences in patterns of de novo metastasis and evaluated the association between site of de novo metastasis and breast, prostate, and colorectal cancer mortality. Data were obtained from the Surveillance Epidemiology and Ends Results (SEER) database from 2010 to 2013 and included 520,147 patients ages ≥40 years with primary diagnosis of breast, colorectal, or prostate cancer. Site and frequency of de novo metastases to four sites (bone, brain, liver, and lung) were compared by race/ethnicity using descriptive statistics, and survival differences examined using extended Cox regression models in SAS 9.4. Overall, non‐Hispanic (NH) Blacks (11%) were more likely to present with de novo metastasis compared with NH‐Whites (9%) or Hispanics (10%). Among patients with breast cancer, NH‐Blacks were more likely to have metastasis to the bone, (OR: 1.25, 95% CI: 1.15–1.37), brain (OR: 2.26, 95% CI: 1.57–3.25), or liver (OR: 1.62, 95% CI: 1.35–1.93), while Hispanics were less likely to have metastasis to the liver (OR: 0.76, 95% CI: 0.60–0.97) compared with NH‐Whites. Among patients with prostate cancer, NH‐Blacks (1.39, 95% CI: 1.31–1.48) and Hispanics (1.39, 95% CI: 1.29–1.49) were more likely to have metastasis to the bone. Metastasis to any of the four sites evaluated increased overall mortality by threefold (for breast cancer and metastasis to bone) to 17‐fold (for prostate cancer and metastasis to liver). Racial disparities in mortality remained after adjusting for metastasis site in all cancer types evaluated. De novo metastasis is a major contributor to cancer mortality in USA with racial differences in the site, frequency, and associated survival. [ABSTRACT FROM AUTHOR]

Objectives: Intrahepatic (ICC) and extrahepatic (ECC) cholangiocarcinomas are rare tumors that arise from the epithelial cells of the bile ducts, and the etiology of both cancer types is poorly understood. Thus, we utilized the Surveillance, Epidemiology, and End Results (SEER)-Medicare resource to examine risk factors and novel preexisting medical conditions that may be associated with these cancer types. Methods: Between 2000 and 2011, 2,092 ICC and 2,981 ECC cases and 323,615 controls were identified using the SEER-Medicare database. Logistic regression was used to calculate adjusted odds ratios (OR) and 95% confidence intervals (CI). Results: Non-alcoholic fatty liver disease was associated with approximately 3-fold increased risks of ICC (OR = 3.52, 95% CI: 2.87–4.32) and ECC (OR = 2.93, 95% CI: 2.42–3.55). Other metabolic conditions, including obesity and type 2 diabetes, were also associated with increased risks of both cancer types. Smoking was associated with a 46% and 77% increased ICC and ECC risk, respectively. Several autoimmune/inflammatory conditions, including type 1 diabetes and gout, were associated with increased risks of ICC/ECC. As anticipated, viral hepatitis, alcohol-related disorders, and bile duct conditions were associated with both cancer types. However, thyrotoxicosis and hemochromatosis were associated with an increased risk of ICC but not ECC, but did not remain significantly associated after Bonferroni correction. Conclusions: In this study, risk factors for ICC and ECC were similar, with the exceptions of thyrotoxicosis and hemochromatosis. Notably, metabolic conditions were associated with both cancer types. As metabolic conditions are increasing in prevalence, these could be increasingly important risk factors for both types of cholangiocarcinoma. [ABSTRACT FROM AUTHOR]

- Abstract
Few studies in the United States have examined longitudinally the mortality risks associated with use of smokeless tobacco (SLT). The sample of our study was composed of participants from the National Longitudinal Mortality Study who completed a single Tobacco Use Supplement to the Current Population Survey between the years 1985 and 2011. Using survival methods, SLT use at the baseline survey was examined as a predictor of all-cause mortality and cause-specific mortalities in models that excluded individuals who had ever smoked cigarettes, cigars or used pipes (final n = 349,282). The participants had median and maximum follow-up times of 8.8 and 26.3 years, respectively. Regression analyses indicated that compared to the never tobacco users, the current SLT users did not have elevated mortality risks from all cancers combined, the digestive system cancers and cerebrovascular disease. However, current SLT users had a higher mortality risk for coronary heart disease (CHD) [hazard ratio (HR) (95% CI) = 1.24 (1.05, 1.46)] relative to never tobacco users. In a separate model, the elevated risk for CHD mortality corresponded to the use of moist snuff [HR (95% CI) = 1.30 (1.03, 1.63)]. The associations with CHD mortality could be attributed to long-term nicotine exposure, other SLT constituents ( e.g., metals) or the confounding effects of CHD risk factors not accounted for in our study. The study's findings contribute to the ongoing dialogue on tobacco harm reduction and the US FDA's evaluation of Modified Risk Tobacco Product applications submitted by American SLT manufacturers.

Background: Testicular germ cell tumors (TGCTs) are rare tumors in the general population but are the most commonly occurring malignancy among males between ages 15 and 44 years in the United States (US). Although non-Hispanic whites (NHWs) have the highest incidence in the US, rates among Hispanics have increased the most in recent years. To forecast what these incidence rates may be in the future, an analysis of TGCT incidence in the Surveillance, Epidemiology, and End Results program and the National Program of Cancer Registries was conducted.Methods: TGCT incidence data among males ages 15 to 59 years for the years 1999 to 2012 were obtained from 39 US cancer registries. Incidence rates through 2026 were forecast using age-period-cohort models stratified by race/ethnicity, histology (seminoma, nonseminoma), and age.Results: Between 1999 and 2012, TGCT incidence rates, both overall and by histology, were highest among NHWs, followed by Hispanics, Asian/Pacific Islanders, and non-Hispanic blacks. Between 2013 and 2026, rates among Hispanics were forecast to increase annually by 3.96% (95% confidence interval, 3.88%-4.03%), resulting in the highest rate of increase of any racial/ethnic group. By 2026, the highest TGCT rates in the US will be among Hispanics because of increases in both seminomas and nonseminomas. Rates among NHWs will slightly increase, whereas rates among other groups will slightly decrease.Conclusions: By 2026, Hispanics will have the highest rate of TGCT of any racial/ethnic group in the US because of the rising incidence among recent birth cohorts. Reasons for the increase in younger Hispanics merit further exploration. Cancer 2017;123:2320-2328. © 2017 American Cancer Society. [ABSTRACT FROM AUTHOR]- Published

The objective of the current study was to investigate the impact of country of birth on age at the time of HCC diagnosis in the United States.Methods: Incident HCC cases diagnosed between 2000 and 2012 in the Surveillance, Epidemiology, and End Results program 18 registry were included. Factors associated with very early onset (age at diagnosis < 40 years) and early onset (age at diagnosis < 50 years) were identified by logistic regression.Results: A total of 59,907 patients were included. The median age at the time of diagnosis of HCC was 62 years and 76% of the patients were male. Of the 75% of patients for whom information regarding birth country was available, 29% were foreign born. In multivariate logistic regression, birth in West Africa (adjusted odds ratio [AOR], 16.3; 95% confidence interval [95% CI], 9.2-27.9 [P<.01]), Central/South/other Africa (AOR, 11.0; 95% CI, 4.5-23.7 [P<.01]), Oceania (AOR, 4.9; 95% CI, 2.9-8.0 [P<.01]), and East Africa (AOR, 3.5; 95% CI, 1.5-6.8 [P<.01]) was found to have the strongest association with very early-onset HCC after adjusting for sex and race/ethnicity. Birth in West Africa, Central/South/other Africa, Oceania, or East Africa also was found to be strongly associated with early-onset HCC.Conclusions: Birth country was found to be independently associated with age at the time of HCC diagnosis in the United States. Birth in Africa (except for North Africa) and Oceania was strongly associated with very early-onset HCC. These findings have implications for the design of comprehensive HCC surveillance programs in the United States. Cancer 2016. © 2016 American Cancer Society.

Background: Telomere shortening is an important molecular event in hepatocellular carcinoma (HCC) initiation; however, its role in HCC progression and prognosis is less clear. Our study aimed to examine the association of telomere length with survival of patients with HCC. Methods: We measured telomere length in tumor and adjacent non-tumor tissues from 126 persons with HCC in the United States (U.S.) who were followed for mortality outcomes. Relative telomere length (RTL) was measured by a monochrome multiplex quantitative polymerase chain reaction assay. Multivariable Cox proportional hazards modeling was used to calculate hazard ratios (HRs) and 95% CIs for the association between telomere length and all-cause mortality. We also examined associations between telomere length and patient characteristics using multiple linear regression. Results: During a mean follow-up of 6.0 years, 79 deaths occurred among 114 individuals for whom survival data were available. The ratio of RTL in tumor relative to non-tumor tissue was greater for individuals with regional or distant stage tumors (0.97) than localized stage tumors (0.77), and for individuals with grade III or IV tumors (0.95) than grade II (0.88) or grade I (0.67) tumors. An RTL ratio ≥1 was not associated with survival (HR 0.92, 95% CI 0.55, 1.55) compared to a ratio <1, after adjusting for age at diagnosis, sex, tumor stage and tumor size. Similarly, RTL in the tumor and non-tumor tissue, respectively, were not associated with survival. Conclusions: This U.S. based study found that telomeres may be longer in more aggressive HCCs. There was no evidence, however, that telomere length was associated with survival of patients with HCC. Future investigations are warranted to clarify the role of telomere length in HCC prognosis.

Background: Hepatocellular carcinoma (HCC) incidence has been increasing in the United States for several decades; and, as the incidence of hepatitis C virus (HCV) infection declines and the prevalence of metabolic disorders rises, the proportion of HCC attributable to various risk factors may be changing.Methods: Data from the Surveillance, Epidemiology, and End Results-Medicare linkage were used to calculate population attributable fractions (PAFs) for each risk factor over time. Patients with HCC (n = 10,708) who were diagnosed during the years 2000 through 2011 were compared with a 5% random sample of cancer-free controls (n = 332,107) residing in the Surveillance, Epidemiology, and End Results areas. Adjusted odds ratios (ORs) and PAFs were calculated for HCV, hepatitis B virus (HBV), metabolic disorders, alcohol-related disorders, smoking, and genetic disorders.Results: Overall, the PAF was greatest for metabolic disorders (32%), followed by HCV (20.5%), alcohol (13.4%), smoking (9%), HBV (4.3%), and genetic disorders (1.5%). The PAF for all factors combined was 59.5%. PAFs differed by race/ethnicity and sex. Metabolic disorders had the largest PAF among Hispanics (PAF, 39.3%; 95% confidence interval [CI], 31.9%-46.7%) and whites (PAF, 34.8%; 95% CI, 33.1%-36.5%), whereas HCV had the largest PAF among blacks (PAF, 36.1%; 95% CI, 31.8%-40.4%) and Asians (PAF, 29.7%; 95% CI, 25.9%-33.4%). Between 2000 and 2011, the PAF of metabolic disorders increased from 25.8% (95% CI, 22.8%-28.9%) to 36% (95% CI, 33.6%-38.5%). In contrast, the PAFs of alcohol-related disorders and HCV remained stable.Conclusions: Among US Medicare recipients, metabolic disorders contribute more to the burden of HCC than any other risk factor, and the fraction of HCC caused by metabolic disorders has increased in the last decade.

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.

Background: The incidence of testicular germ cell tumors (TGCTs) in the United States is notably higher among white men versus other men. Previously, however, it was reported that rates were rising among Hispanics in certain areas. To determine whether this finding was evident in a wider area of the United States, data from 39 US cancer registries were examined.Methods: Racial/ethnic-specific incidence rates per 100,000 man-years were calculated overall and by census region for the period of 1998-2011. Annual percentage changes (APCs) were estimated, and joinpoint models were fit. Differences in incidence by region were examined with the Wald test.Results: From 1998 to 2011, 88,993 TGCTs were recorded. The TGCT incidence was highest among non-Hispanic whites (6.57 per 100,000), who were followed by Hispanics (3.88), American Indians/Alaska Natives (2.88), Asians/Pacific Islanders (A/PIs; 1.60), and non-Hispanic blacks (1.20). The incidence significantly increased among Hispanics (APC, 2.31; P < .0001), with rates rising in all regions except the South. Rates rose slightly among non-Hispanic whites (APC, 0.51; P = .0076). Significant differences in rates by region were seen for Hispanics (P = .0001), non-Hispanic whites (P < .0001), and A/PIs (P < .0001), with the highest rates among Hispanics in the West and with the highest rates among non-Hispanic whites and A/PIs in the Northeast.Conclusions: Although the incidence of TGCTs remained highest among non-Hispanic whites between 1998 and 2011, the greatest increase was experienced by Hispanics. Rising rates of TGCTs among Hispanics in the United States suggest that future attention is warranted. Reasons for the increase may include variability in birthplace, changing exposures, genetic susceptibility, and the length of US residence. [ABSTRACT FROM AUTHOR]- Published

CHOLANGIOCARCINOMA ,INTRAHEPATIC bile ducts ,LIVER cancer ,ETIOLOGY of cancer - Abstract
Background: Intrahepatic (ICC) and extrahepatic cholangiocarcinomas (ECC) are tumors that arise from cholangiocytes in the bile duct, but ICCs are coded as primary liver cancers while ECCs are coded as biliary tract cancers. The etiology of these tumors is not well understood. It has been suggested that the etiology of ICC is more similar to that of another type of liver cancer, hepatocellular carcinoma (HCC), than to the etiology of ECC. If this is true, geographic incidence patterns and trends in ICC incidence should be more similar to that of HCC than ECC. Methods: To examine this hypothesis, data from the North American Association of Central Cancer Registries Cancer in North America data file were analyzed. Incidence rates and joinpoint trends were calculated by demographic subgroup. County-level incidence rates were mapped. Results: Overall incidence rates, racial distribution, male:female ratio, and peak ages were more similar between ICC and ECC than with HCC. During 2000–2009, average annual incidence rates of ECC increased. During 2005–2009, average annual ICC incidence rates also increased. High rates for all three cancer sites were found in the Pacific region, particularly Hawaii and Alaska. Rates of ICC and ECC were also high in the Northeast and the upper Midwest, while rates of HCC were high in the South. Conclusions: Demographic patterns and geographical variation were more closely related between ICC and ECC than HCC, suggesting that the etiology of ICC and ECC may be similar. Increasing rates of both tumors suggest that further etiology studies are warranted. [ABSTRACT FROM AUTHOR]

Purpose: Human papillomavirus (HPV) is a major risk factor for specific cancers of the head and neck, particularly malignancies of the tonsil and base of the tongue. However, the role of HPV in the development of laryngeal cancer has not been definitively established. We conducted a population-based, cancer registry study to evaluate and characterize the genotype-specific prevalence of HPV in invasive laryngeal cancer cases diagnosed in the U.S. Methods: The presence of genotype-specific HPV DNA was evaluated using the Linear Array HPV Genotyping Test and the INNO-LiPA HPV Genotyping Assay in formalin-fixed paraffin embedded tissue from 148 invasive laryngeal cancer cases diagnosed in 1993–2004 within the catchment area of three U.S. SEER cancer registries. Results: HPV DNA was detected in 31 of 148 (21%) invasive laryngeal cancers. Thirteen different genotypes were detected. Overall, HPV 16 and HPV 33 were the most commonly detected types. HPV was detected in 33% (9/27) of women compared with 18% (22/121) of men (p = 0.08). After adjustment for age and year of diagnosis, female patients were more likely to have HPV-positive laryngeal tumors compared to males (adjusted OR 2.84, 95% CI 1.07–7.51). Viral genotype differences were also observed between the sexes. While HPV 16 and 18 constituted half of HPV-positive cases occurring in men, among women, only 1 was HPV 16 positive and none were positive for HPV 18. Overall 5-year survival did not vary by HPV status. Conclusions: HPV may be involved in the development of a subset of laryngeal cancers and its role may be more predominant in women compared to men.

BACKGROUND The objectives of this article are to assess the completeness of the data collected on site-specific factors (SSFs) as a part of Collaborative Stage (CS) version 2 and the impact of the transition from the American Joint Committee on Cancer's (AJCC) 6th to 7th edition guidelines on stage distribution. METHODS Incidence data for melanomas of the skin from 18 Surveillance, Epidemiology, and End Results (SEER) registries (SEER-18) were analyzed. Percentages of unknown cases for 7 SSFs were examined, along with staging trends from 2004 to 2010 and differences in AJCC 6th and 7th edition stage distributions for 2010 cases. RESULTS Fewer than 10% of cases were coded as unknown for SSFs 1 (measured thickness), 2 (ulceration), and 3 (lymph node metastasis). For the remaining SSFs, 36-81% of cases were coded as unknown. Stage distributions were relatively consistent across time and between the AJCC 6th and 7th editions, with the exception of stage IA and stage INOS (not otherwise specified), for which a shift in cases was observed between the AJCC 6th and 7th edition guidelines fOR 2010 cases. CONCLUSIONS A shift of cases out of stage IA and into stage INOS was observed between the AJCC 6th and 7th edition guidelines for 2010 cases. This was attributed to the high number of cases coded as unknown for SSF7 (primary tumor mitotic count/rate). The percentage of cases coded as unknown varied by SSF. Data completeness presents an issue for SSFs introduced in CS version 2. Cancer 2014;120(23 suppl):3807-14. © 2014 American Cancer Society. [ABSTRACT FROM AUTHOR]

BACKGROUND The American Joint Committee on Cancer's (AJCC) 7th edition cancer staging manual reflects recent changes in cancer care practices. This report assesses changes from the AJCC 6th to the AJCC 7th edition stage distributions and the quality of site-specific factors (SSFs). METHODS Incidence data for renal parenchyma and pelvis and ureter cancers from 18 Surveillance, Epidemiology, and End Results (SEER) registries were examined, including staging trends during 2004-2010, stage distribution changes between the AJCC 6th and 7th editions, and SSF completeness for cases diagnosed in 2010. RESULTS From 2004 to 2010, the percentage of stage I renal parenchyma cancers increased from 50% to 58%, whereas stage IV and unknown stage cases decreased (18% to 15%, and 10% to 6%, respectively). During this period, the percentage of stage 0a renal pelvis and ureter cancers increased from 21% to 25%, and stage IV and unknown stage tumors decreased (20% to 18%, and 7% to 5%, respectively). Stage distributions under the AJCC 6th and 7th editions were about the same. For renal parenchymal cancers, 71%-90% of cases had known values for 6 required SSFs. For renal pelvis and ureter cancers, 74% of cases were coded as known for SSF1 (WHO/ISUP grade) and 47% as known for SSF2 (depth of renal parenchymal invasion). SSF values were known for larger proportions of cases with reported resections. CONCLUSIONS Stage distributions between the AJCC 6th and 7th editions were similar. SSFs were known for more than two-thirds of cases, providing more detail in the SEER database relevant to prognosis. Cancer 2014;120(23 suppl):3826-35. © 2014 American Cancer Society.

BACKGROUND Uterine cancer is the fourth leading cancer among US women. Changes in uterine cancer staging were made from the American Joint Committee on Cancer (AJCC) 6th to 7th edition staging manuals, and 8 site-specific factors (SSFs) and 3 histologic schemas were introduced. Carcinomas account for 95% of cases and are the focus of this report. METHODS Distributions of SSF values were examined for 11,601 cases of malignant cancer of the corpus uteri and uterus, NOS (not otherwise specified) diagnosed in Surveillance, Epidemiology, and End Results (SEER) Program registries during 2010. AJCC 6th and 7th edition staging distributions were compared for 11,176 cases using data in both staging systems. AJCC 6th edition staging distributions during 2004-2010 were examined. AJCC 7th edition SSFs required by SEER were International Federation of Gynecology and Obstetrics stage (SSF1), peritoneal cytology (SSF2), number of positive pelvic lymph nodes (SSF3), number of pelvic lymph nodes examined (SSF4), number of positive para-aortic lymph nodes (SSF5), and number of para-aortic lymph nodes examined (SSF6). RESULTS For SSFs related to lymph nodes, a third of cases were classified as 'not applicable,' reflecting that lymph node dissection is not indicated for cases with stage1A and stage 4 diagnoses. AJCC 7th edition criteria assigned more cases to stage I (72.9%) than AJCC 6th edition criteria (68.7%). Annual counts significantly increased during 2004-2010, as did counts for AJCC 6th edition stages INOS, IA, IB, IC, IIIA, IIIB, IIIC, and IVB. The proportion of cases diagnosed with stage I cancer was stable, whereas stages II and IV decreased and stage III increased. CONCLUSIONS Five SSFs were suitable for analysis: peritoneal cytology results (SSF2), numbers of positive pelvic lymph nodes (SSF3), pelvic lymph nodes examined (SSF4), positive para-aortic lymph nodes (SSF5), and para-aortic lymph nodes examined (SSF6).

BACKGROUND The Collaborative Stage (CS) Data Collection System enables multiple cancer registration programs to document anatomic and molecular pathology features that contribute to the Tumor (T), Node (N), Metastasis (M) - TNM - system of the American Joint Committee on Cancer (AJCC). This article highlights changes in CS for colon and rectal carcinomas as TNM moved from the AJCC 6th to the 7th editions. METHODS Data from 18 Surveillance, Epidemiology, and End Results (SEER) population-based registries were analyzed for the years 2004-2010, which included 191,361colon and 73,341 rectal carcinomas. RESULTS Overall, the incidence of colon and rectal cancers declined, with the greatest decrease in stage 0. The AJCC's 7th edition introduction of changes in the subcategorization of T4, N1, and N2 caused shifting within stage groups in 25,577 colon and 10,150 rectal cancers diagnosed in 2010. Several site-specific factors (SSFs) introduced in the 7th edition had interesting findings: 1) approximately 10% of colon and rectal cancers had tumor deposits - about 30%-40% occurred without lymph node metastases, which resulted in 2.5% of colon and 3.3% of rectal cases becoming N1c (stage III A/B) in the AJCC 7th edition; 2) 10% of colon and 12% of rectal cases had circumferential radial margins <1 mm; 3) about 46% of colorectal cases did not have a carcinoembryonic antigen (CEA) testing or documented CEA information; and 4) about 10% of colorectal cases had perineural invasion. CONCLUSIONS Adoption of the AJCC 7th edition by the SEER program provides an assessment tool for staging and SSFs on clinical outcomes. This evidence can be used for education and improved treatment for colorectal carcinomas. Cancer 2014;120(23 suppl):3793-806. © 2014 American Cancer Society. [ABSTRACT FROM AUTHOR]

BACKGROUND To evaluate whether progress continues in identifying more effective treatments for children and adolescents with cancer, the authors examined both overall and disease-specific childhood cancer mortality rates for the United States, focusing on data from 2000 to 2010. METHODS Age-adjusted US mortality trends from 1975 to 2010 were estimated using joinpoint regression analysis. Analyses of annual percentage change (APC) were performed on the same diagnostic groupings for the period restricted to 2000 through 2010 for groupings ages <20 years, <15 years, and 15 to 19 years. RESULTS After a plateau in mortality rates during 1998 to 2002 (APC, 0.3%), the annual decline in childhood cancer mortality from 2002 to 2010 (APC, −2.4%) was similar to that observed from 1975 to 1998 (APC, −2.7%). Statistically significant declines in mortality rates from 2000 to 2010 were noted for acute lymphoblastic leukemia, acute myeloid leukemia, non-Hodgkin lymphoma, Hodgkin lymphoma, neuroblastoma, central nervous system cancers, and gonadal cancers. From 2000 to 2010, the rates of decline in mortality for the group ages 15 to 19 years generally were equal to or greater than the rates of decline for the group ages birth to 14 years. Improvements in treatment since 1975 resulted >45,000 cancer deaths averted through 2010. CONCLUSIONS Cancer mortality for both children and adolescents declined from 2000 to 2010, with significant declines observed for multiple cancer types. However, greater than 1900 cancer deaths still occur each year among children and adolescents in the United States, and many survivors experience long-term effects that limit their quality of life. Continued research directed toward identifying more effective treatments that produce fewer long-term sequelae is critical to address these remaining challenges. Cancer 2014;120:2497-2506.

Background In 2010, Surveillance, Epidemiology, and End Results (SEER) registries began collecting human epidermal growth factor 2 (HER2) receptor status for breast cancer cases. Methods Breast cancer subtypes defined by joint hormone receptor (HR; estrogen receptor [ER] and progesterone receptor [PR]) and HER2 status were assessed across the 28% of the US population that is covered by SEER registries. Age-specific incidence rates by subtype were calculated for non-Hispanic (NH) white, NH black, NH Asian Pacific Islander (API), and Hispanic women. Joint HR/HER2 status distributions by age, race/ethnicity, county-level poverty, registry, stage, Bloom-Richardson grade, tumor size, and nodal status were evaluated using multivariable adjusted polytomous logistic regression. All statistical tests were two-sided. Results Among case patients with known HR/HER2 status, 36810 (72.7%) were found to be HR
+ /HER2- , 6193 (12.2%) were triple-negative (HR- /HER2- ), 5240 (10.3%) were HR+ /HER2+ and 2328 (4.6%) were HR- /HER2+ ; 6912 (12%) had unknown HR/HER2 status. NH white women had the highest incidence rate of the HR+ /HER2- subtype, and NH black women had the highest rate of the triple-negative subtype. Compared with women with the HR- /HER2+ subtype, triple-negative patients were more likely to be NH black and Hispanic; HR- /HER2+ patients were more likely to be NH API; and HR- /HER2+ patients were more likely to be NH black, NH API, and Hispanic. Patients with triple-negative, HR+ /HER2+ , and HR- /HER2+ breast cancer were 10% to 30% less likely to be diagnosed at older ages compared with HR+ /HER2- patients and 6.4-fold to 20.0-fold more likely to present with high-grade disease. Conclusions In the future, SEER data can be used to monitor clinical outcomes in women diagnosed with different molecular subtypes of breast cancer for a large portion (approximately 28%) of the US population.

OBJECTIVES:The objectives were to describe Surveillance, Epidemiology and End Results (SEER) hepatocellular carcinoma (HCC) incidence trends and the US liver cancer mortality trends by geography, age, race/ethnicity, and gender.METHODS:HCC incidence data from SEER 18 registries and liver cancer mortality data from the National Center for Health Statistics were analyzed. Rates and joinpoint trends were calculated by demographic subgroup. State-level liver cancer mortality rates and trends were mapped.RESULTS:HCC incidence rates in SEER registries did not significantly increase during 2007-2010; however, the US liver cancer mortality rates did increase. HCC incidence and liver cancer mortality rates increased among black, Hispanic, and white men aged 50+ years and decreased among 35-49-year-old men in all racial/ethnic groups including Asians/Pacific Islanders. Significantly increasing incidence and mortality rates among women were restricted to blacks, Hispanics, and whites aged 50+ years. Asian/Pacific Islander liver cancer mortality rates decreased during 2000-2010 with decreasing rates among women aged 50-64 years and men aged 35-49 years and stable rates in other groups. During 2006-2010, among individuals 50-64 years of age, blacks and Hispanics had higher incidence and mortality rates than Asians/Pacific Islanders. Liver cancer mortality rates were highest in Louisiana, Mississippi, Texas, and Washington, DC.CONCLUSIONS:Decreasing HCC incidence and liver cancer mortality rates among Asians/Pacific Islanders, men aged 35-49 years, and the nonsignificant increase in overall HCC incidence rates suggest that the peak of the epidemic may be near or have passed. Findings of geographic variation in mortality rates can inform control efforts. [ABSTRACT FROM AUTHOR]

Human immunodeficiency virus (HIV) infection substantially elevates diffuse large B-cell lymphoma (DLBCL) risk, but its impact on the distinct DLBCL subtypes defined by cell of origin is unclear. We compared DLBCL molecular characteristics and prognosis in 51 HIV-infected and 116 HIV-uninfected cases diagnosed during 1977-2003. Using immunohistochemistry to classify cell of origin based on the Tally algorithm, activated B-cell (ABC)-DLBCL was substantially more common in HIV-infected (83%) than in HIV-uninfected (54%) cases ( p < 0.001). Epstein-Barr virus (EBV) was detected in 63% of DLBCLs in HIV-infected cases, occurring almost exclusively in ABC-DLBCL (74% vs. 13% of germinal center B-cell [GCB]-DLBCL, p = 0.002), but was rarely detected in DLBCLs among HIV-uninfected cases (3%). Among HIV-uninfected cases, MYC/IgH [t(8;14)(q24;q32)] and IgH/BCL2 [t(14;18)(q32;q21)] translocations were significantly more common and BCL6/IgH [t(3;14)(q27;q32)] significantly less common in GCB-DLBCL than in ABC-DLBCL ( p = 0.010, < 0.001 and = 0.039, respectively). Among HIV-infected cases, translocations other than MYC/IgH [t(8;14)(q24;q32)] (21%) were rare (≤ 6%) and unrelated to cell of origin. ABC-DLBCL was associated with adverse overall survival compared with GCB-DLBCL regardless of HIV status ( p
HIV-infected = 0.066; pHIV-uninfected = 0.038). Our data demonstrate key differences in the molecular characteristics, cell of origin and prognosis of DLBCL by HIV status in the pre-highly active antiretroviral therapy (HAART) and pre-rituximab era, supporting biologic differences in lymphomagenesis in the presence of HIV.

Background: Human papillomavirus (HPV) is estimated to play an etiologic role in 40-50% of penile cancers worldwide. Estimates of HPV prevalence in U.S. penile cancer cases are limited. Methods: HPV DNA was evaluated in tumor tissue from 79 invasive penile cancer patients diagnosed in 1998-2005 within the catchment areas of seven U.S. cancer registries. HPV was genotyped using PCR-based Linear Array and INNO-LiPA assays and compared by demographic, clinical, and pathologic characteristics and survival. Histological classification was also obtained by independent pathology review. Results: HPV DNA was present in 50 of 79 (63%) of invasive penile cancer cases. Sixteen viral genotypes were detected. HPV 16, found in 46% (36/79) of all cases (72% of HPVpositive cases) was the most prevalent genotype followed equally by HPV 18, 33, and 45, each of which comprised 5% of all cases. Multiple genotypeswere detected in 18% of viral positive cases. HPV prevalence did not significantly vary by age, race/ethnicity, population size of geographic region, cancer stage, histology, grade, penile subsite, or prior cancer history. Penile cases diagnosed in more recent years were more likely to be HPV-positive. Overall survival did not significantly vary by HPV status. Conclusion: The relatively high prevalence of HPV in our study population provides limited evidence of a more prominent and, possibly, increasing role of infection in penile carcinogenesis in the U.S. compared to other parts of the world.

Background. Breast cancer survival has improved significantly in the US in the past 10-15 years. However, disparities exist in breast cancer survival between black and white women. Purpose. To investigate the effect of county healthcare resources and SES as well as individual SES status on breast cancer survival disparities between black and white women. Methods. Data from1,796 breast cancer cases were obtained from the Surveillance Epidemiology and End Results and the National Longitudinal Mortality Study dataset. Cox Proportional Hazards models were constructed accounting for clustering within counties. Three sequential Cox models were fit for each outcome including demographic variables; demographic and clinical variables; and finally demographic, clinical, and county-level variables. Results. In unadjusted analysis, black women had a 53% higher likelihood of dying of breast cancer and 32% higher likelihood of dying of any cause (P < 0.05) compared with white women. Adjusting for demographic variables explained away the effect of race on breast cancer survival (HR, 1.40; 95% CI, 0.99-1.97), but not on all-cause mortality. The racial difference in all-cause survival disappeared only after adjusting for county-level variables (HR, 1.27; CI, 0.95-1.71). Conclusions. Improving equitable access to healthcare for all women in the US may help eliminate survival disparities between racial and socioeconomic groups. [ABSTRACT FROM AUTHOR]

Pancreatic ductal adenocarcinoma (PDAC) is an important cause of cancer death with no clear prognostic biomarker. Expression of prion (PrP) has been reported to be a marker of poor prognosis in a series of Caucasian PDAC cases. We determined the prognostic value of PrP in a racially and geographically diverse population-based series of PDAC cases. PrP expression was examined in 142 PDAC cases from three cancer registries. Cases included 71 Caucasian, 54 Asian/Pacific Islanders and 17 Blacks diagnosed from 1983-2000, and followed through 2008. Hazard ratios (HR) and 95% confidence intervals (CIs) for the association of PrP expression with survival were computed after adjustment for case attributes. The risk of death was about four times higher (HR=3.8; 95% PDAC cases with PrP^{+} tumors (median survival 5 months) compared to the 34 cases with PrP^{-} tumors (median survival 20 months). Of 51 cases with resected, localized PDAC median survival was 74 months for 17 cases with PrP^{-} tumors versus 14 months for 34 cases with PrP^{+} tumors (HR=6.7; 95% CI: 2.6, 17.4). All 6 surviving cases had PrP^{-} negative tumors (median survival, > 10 years). PrP may have potential as a prognostic biomarker in PDAC patient management. [ABSTRACT FROM AUTHOR]

US Department of Agriculture Food Safety and Inspection Service (FSIS) data on Salmonella enterica serotype Enteritidis in broiler chicken carcass rinses collected from 2000 through 2005 showed the annual number of isolates increased >4-fold and the proportion of establishments with Salmonella Enteritidis-positive rinses increased nearly 3-fold (test for trend, p<0.0001). The number of states with Salmonella Enteritidis in broiler rinses increased from 14 to 24. The predominant phage types (PT) were PT 13 and PT 8, 2 strains that a recent Foodborne Diseases Active Surveillance Network (FoodNet) case-control study associated with eating chicken. FSIS is directing more sampling resources toward plants with marginal Salmonella control to reduce prevalence in products including broilers. The policy targets establishments with common Salmonella serotypes of human illness, including Salmonella Enteritidis. Voluntary interventions should be implemented by industry.

Salmonella enterica serotype Enteritidis emerged as an important illness during the 1980s. Investigations showed that consumption of undercooked eggs was the major risk factor for disease, and a variety of prevention and control efforts were initiated during the 1990s. We describe sporadic infections and outbreaks of S. Enteritidis in the United States from 1985 through 1999 and discuss prevention and control efforts. After reaching a high of 3.9 per 100,000 population in 1995, S. Enteritidis infections declined to 1.98 per 100,000 in 1999. While the total number of outbreaks decreased by half, those in the western states tripled. Outbreaks of S. Enteritidis phage type 4 infections accounted for 49% of outbreaks in 1999. Outbreak-associated deaths in health facilities decreased from 14 in 1987 to 0 in 1999. Overall, rates of sporadic S. Enteritidis infection, outbreaks, and deaths have declined dramatically. For further reductions, control measures should continue to be applied along the entire farm-to-table continuum. [ABSTRACT FROM AUTHOR]

Campylobacter jejuni is the most commonly reported bacterial cause of foodborne infection in the United States. Adding to the human and economic costs are chronic sequelae associated with C. jejuni infection--Guillian-Barré syndrome and reactive arthritis. In addition, an increasing proportion of human infections caused by C. jejuni are resistant to antimicrobial therapy. Mishandling of raw poultry and consumption of undercooked poultry are the major risk factors for human campylobacteriosis. Efforts to prevent human illness are needed throughout each link in the food chain. [ABSTRACT FROM AUTHOR]

The incidence of esophageal adenocarcinoma in white males has been increasing steadily over the past decade. However, attempts to identify the precursor lesion, intestinal metaplasia of the esophagus, or early in-situ cancers have been dismal, with no increase in the diagnosis of early cancers over 9 years of follow-up, as noted in the study by Cooper et al. Important predictors of survival, such as a previous diagnosis of gastroesophageal reflux disease, endoscopy, and the diagnosis of intestinal metaplasia, continue to represent a minority of patients who present with esophageal adenocarcinoma. A discussion on the possible pathophysiology, and reasons for the poor diagnostic yields in spite of performing more endoscopies, are presented. It may be that most patients are relatively asymptomatic, or have very distal, endoscopically imperceptible intestinal metaplasia. Over time, factors that encourage localized, distal esophageal reflux may be the insidious culprit that leads to intestinal metaplasia.Am J Gastroenterol 2009; 104:1363–1365; doi:10.1038/ajg.2009.167; published online 12 May 2009 [ABSTRACT FROM AUTHOR]

Objectives. This study describes the epidemiology of raw milk-associated outbreaks reported to the Centers for Disease Control and Prevention from 1973 through 1992. Methods. Surveillance data for each reported raw milk-associated outbreak were reviewed. A national survey was conducted to determine the legal status of intrastate raw milk sales for the period 1973 through 1995. Results. Forty-six raw milk-associated outbreaks were reported during the study period; 40 outbreaks (87%) occurred in states where the intrastate sale of raw milk was legal. Conclusions. Consumption of raw milk remains a preventable cause of foodborne disease outbreaks. [ABSTRACT FROM AUTHOR]
