Impact of tomosynthesis on the evolution of the cancer detection rate in the French National Breast Cancer Screening Program.

Objectives: This study aims to evaluate the cancer detection rate in French National Breast Cancer Screening Program, especially the cancer detection rate during second reading session (Reading 2) based on digital technologies used in radiology centres.

Study Design: This was an analytical and descriptive study.

Methods: Cancer detection rate was estimated by the ratio between the number of cancers detected and the number of women screened.

[Second reading in breast cancer screening program: State of knowledge and future].

Second reading is an important part of breast cancer organized screening program. Image quality control and detection of non-diagnosed cancer by first reader are the two goals of this process. In France, 6 % of all screening cancer are diagnosed by second reading, actually done on screen film.

Breast cancer incidence by age at discovery of mammographic abnormality in women participating in French organized screening campaigns.

Objective: Statistical modeling was already predicted the occurrence/prognosis of breast cancer from previous radiological findings. This study predicts the breast cancer risk by the age at discovery of mammographic abnormality in the French breast cancer screening program.

Study Design: This was a cohort study.

Colorectal cancer fecal screening test completion after age 74, sources and outcomes in French program.

Background: Elderly patients aged at least 75 years old (Elderly_75), represent 45% of colorectal cancer (CRC) incidence. As others, the French Colorectal Cancer Screening Program (CRCSP) does not include Elderly_75. To date, there is little evidence to justify stopping screening at 74 years of age.

With the collaboration of all coordinating physicians responsible for breast cancer screening in France, the authors studied factors related to personal history, mammographic characteristics prior to the diagnosis and the tumours of women with breast cancers larger than 20 mm. This retrospective study concerned 7,407 cancers larger than 20 mm diagnosed in the context of screening.Although criteria of tumour aggressiveness were more marked and technological factors were more commonly encountered, compliance with screening appears to be a major determinant in the discovery of these large tumours.

[Breast cancer screening in thirteen French departments].

Background: In France, breast cancer screening programme, free of charge for women aged 50-74 years old, coexists with an opportunistic screening and leads to reduction in attendance in the programme. Here, we reported participation in organized and/or opportunistic screening in thirteen French departments.

Population And Methods: We analyzed screening data (organized and/or opportunistic) of 622,382 women aged 51-74 years old invited to perform an organized mammography screening session from 2010 to 2011 in the thirteen French departments.

Mammographic density and urbanization: a population-based screening study.

Objectives: The high incidence of female breast cancer that has been consistently reported in urban areas could be mediated by breast density, which is considered to reflect the cumulative exposure of breast tissues to hormones. The aim of this study was to assess how mammographic density varies by the degree of urbanization.

Setting: The population consisted of 55,597 cancer-free women, aged 50-59 years, who participated in a French breast cancer screening programme (Franche-Comté region) between 2005 and 2009.

Trends in invasive breast cancer incidence among French women not exposed to organized mammography screening: an age-period-cohort analysis.

Background: The long tenure of the Doubs cancer registry (France) and the late implementation of a mass screening program provide a unique opportunity to assess the relative contributions of age, period and cohort effects to the increase in female invasive breast cancer incidence, while avoiding the influence of an organized screening program.

Methods: Population and incidence data were provided for the Doubs region during the 1978-2003 period. Breast cancer counts and person-years were tabulated into 1-year classes by age and time period.

Usefulness of weekly methicillin-resistant Staphylococcus aureus screening.

We evaluated the usefulness of adding weekly methicillin-resistant Staphylococcus aureus (MRSA) screening to our established admission screening and clinical sampling in 4 acute care units of a university hospital. Our results suggest that weekly MRSA screening allows the detection of 56.1% of all cases of hospital-acquired MRSA carriage.

Residential exposure to radiofrequency fields from mobile phone base stations, and broadcast transmitters: a population-based survey with personal meter.

Objectives: Both the public perceptions, and most published epidemiologic studies, rely on the assumption that the distance of a particular residence from a base station or a broadcast transmitter is an appropriate surrogate for exposure to radiofrequency fields, although complex propagation characteristics affect the beams from antennas. The main goal of this study was to characterise the distribution of residential exposure from antennas using personal exposure meters.

Methods: A total of 200 randomly selected people were enrolled.
