Surveillance of high-grade cervical cancer precursors (CIN III/AIS) in four population-based cancer registries, United States, 2009-2012.

Surveillance of cervical intraepithelial neoplasia grade III (CIN III) and adenocarcinoma in situ (AIS) is important for determining the burden of a preventable disease, identifying effects of vaccination on future diagnoses, and developing targeted programs. We analyzed population-based rates of high-grade cervical cancer precursor lesions using data from four central cancer registries (diagnosis years 2009-2012 from Louisiana, Kentucky, Michigan, and diagnosis years 2011-2012 from Los Angeles) by age, race, and histology. We also compared rates of precursors to invasive cancers. With 4 complete years of data from Michigan, we were able to conduct a trend analysis for that state. Data analysis was conducted in Atlanta during 2016. Kentucky reported the highest rate of CIN III/AIS (69.8), followed by Michigan (55.4), Louisiana (42.3), and Los Angeles (19.2). CIN III/AIS rates declined among women in Michigan by 37% each year for women aged 15-19, 14% for those aged 20-24, and 7% for those aged 25-29. Rates of CIN III/AIS vary by registry, and were higher than invasive cancer. In Michigan, declines in CIN III/AIS among women aged 15-29 are likely related in part to updated screening recommendations, and to the impact of human papillomavirus vaccination.

Characteristics, rates, and trends of melanoma incidence among Hispanics in the USA.

PURPOSE: The purpose of this study is to describe the epidemiology of melanoma among Hispanics using data that cover nearly 100 % of the US population. METHODS: The study used population-based cancer incidence data from the National Program of Cancer Registries and the Surveillance, Epidemiology and End Results Program to examine melanoma incidence rates and trends among Hispanics by sex, age, race, histology, anatomic location, stage, and tumor thickness. RESULTS: From 2008 to 2012, 6,623 cases of melanoma were diagnosed among Hispanics. Rates were higher among males (4.6) than among females (4.0), but females younger than age 55 had higher rates than males. The most common histologic subtype was superficial spreading melanoma (23 %). Melanomas with poorer outcomes, such as nodular (NM) and acral lentiginous melanoma (ALM), were more common among males. Hispanic females had the highest proportion of melanoma on the lower limb and hip (33.7 %), while Hispanic males had the highest proportion on the trunk (29.9 %). Incidence rates for later-stage diagnosis and thicker tumors were significantly higher among Hispanic men than among women. Incidence rates decreased significantly during 2003-2012 (AAPC = -1.4). CONCLUSIONS: Clinicians and public health practitioners will need to reach the growing Hispanic population in the USA with strategies for primary prevention and early diagnosis of melanoma. Results suggest Hispanics and providers need education to increase awareness about the characteristics of melanoma among Hispanics, including types that occur on non-sun-exposed areas (ALM and NM). Skin cancer prevention and awareness interventions targeting Hispanics should be culturally relevant.

Consumer Response to Gastrointestinal Illness Perceived To Originate from Food Service Facilities.

Consumer responses to food product recalls have been documented, but there is little information on how consumers respond to illnesses or outbreaks associated with food service facilities. This study uses an on-line survey of 885 adults conducted in 2012 to determine how respondents changed their dining behavior following personal experiences with and secondhand reports of gastrointestinal illness believed to be associated with food service facilities. In response to personally experiencing gastrointestinal illness that they attributed to a food service facility, 90% of survey participants reported that they avoided the implicated facility for a time following the incident; almost one-half decided to never return to the facility they believed had made them ill. In response to a secondhand report of gastrointestinal illness, 86% of respondents reported they would avoid the implicated facility for a time, and 22% said they would never return to the facility. After both personal experiences of illness and secondhand reports of illness, consumer responses were significantly more severe toward the implicated facility than toward all other food service facilities. Frequent diners avoided facilities for shorter periods of time and were less likely to never go back to a facility than were infrequent diners. The survey results indicate that 24 to 97 fewer meals were purchased per respondent, or a 11 to 20% reduction in meals purchased outside the home, in the year following respondents' illness. Future estimates of the economic burden of foodborne illnesses, including those caused by noroviruses, should consider the impacts on the food service industry attributable to changes in consumer behavior, in addition to health care costs and loss of productivity.
