OBJECTIVE: We hypothesize that radiologists' estimated percentage likelihood assessments for the presence of ductal carcinoma in situ (DCIS) and invasive cancer may predict histologic outcomes. MATERIALS AND METHODS: Two hundred fifty cases categorized as BI-RADS category 4 or 5 at four University of California Medical Centers were retrospectively reviewed by 10 academic radiologists with a range of 1-39 years in practice. Readers assigned BI-RADS category (1, 2, 3, 4a, 4b, 4c, or 5), estimated percentage likelihood of DCIS or invasive cancer (0-100%), and confidence rating (1 = low, 5 = high) after reviewing screening and diagnostic mammograms and ultrasound images...

BACKGROUND: Most population breast cancer (BC) screening programs use double-reading of 2D-mammography. We recently reported the screening with tomosynthesis or standard mammography-2 (STORM-2) trial, showing that double-read tomosynthesis (pseudo-3D-mammography) detected more BC than double-read 2D-mammography. In this study, we compare screen-detection measures for single-reading of 3D-mammography with those for double-reading of 2D-mammography, to inform screening practice. METHODS: This is a secondary analysis based on STORM-2 which prospectively compared 3D-mammography and 2D-mammography in sequential screen-readings...

INTRODUCTION: Modern full-field digital mammography (FFDM) appears to have increased the detection of breast microcalcification. This retrospective study aimed to assess whether this is associated with over-investigation and possible over-diagnosis of breast pathology of lesser significance. METHODS: Three 2-year periods were studied, in which different mammographic technologies were used exclusively viz., classical screen-film mammography (SFM) in 2003-04, computed radiography (CR) in 2009-10 and FFDM in 2012-13...

Background: Experiencing a false positive (FP) screening mammogram is economically, physically, and emotionally burdensome, which may affect future screening behavior by delaying the next scheduled mammogram or by avoiding screening altogether. We sought to examine the impact of a FP screening mammogram on the subsequent screening mammography behavior.Methods: Delay in obtaining subsequent screening was defined as any mammogram performed more than 12 months from index mammogram. The Kaplan-Meier (product limit) estimator and Cox proportional hazards model were used to estimate the unadjusted delay and the hazard ratio (HR) of delay of the subsequent screening mammogram within the next 36 months from the index mammogram date...

BACKGROUND: In 2009, the U.S. Preventive Services Task Force (USPSTF) recommended biennial mammography for women aged 50-74 years and shared decision-making for women aged 40-49 years for breast cancer screening. We evaluated changes in mammography screening interval after the 2009 recommendations. MATERIALS AND METHODS: We conducted a prospective cohort study of women aged 40-74 years who received 821,052 screening mammograms between 2006 and 2012 using data from the Breast Cancer Surveillance Consortium...

PURPOSE: Fibroglandular tissue may mask breast cancers, thereby reducing the sensitivity of mammography. Here, we investigate methods for identification of women at high risk of a masked tumor, who could benefit from additional imaging. METHODS: The last negative screening mammograms of 111 women with interval cancer (IC) within 12 months after the examination and 1110 selected normal screening exams from women without cancer were used. From the mammograms, volumetric breast density maps were computed, which provide the dense tissue thickness for each pixel location...

PURPOSE: Initial auto-adjustment of the window level WL and width WW applied to mammo-graphic images. The proposed intensity windowing (IW) method is based on the maximization of the mutual information (MI) between a perceptual decomposition of the original 12-bit sources and their screen displayed 8-bit version. Besides zoom, color inversion and panning operations, IW is the most commonly performed task in daily screening and has a direct impact on diagnosis and the time involved in the process...

BACKGROUND: More than a third of hospitalized women are both overdue for breast cancer screening and at high risk for developing breast cancer. The purpose of the study was to evaluate if inpatient breast cancer screening education, scheduling an outpatient mammography appointment before hospital discharge at patients' convenience, phone call reminders, and a small monetary incentive ($10) would result in improved adherence with breast cancer screening for these patients. METHODS: A prospective intervention pilot study was conducted among 30 nonadherent women aged 50-75 years hospitalized to a general medicine service...

<ce:para>Organized breast cancer screening has become available throughout France since 2004. According to the French National Cancer Institute, more than 22 million mammograms have been performed during the first ten years of the screening programme, or about 2.45 million mammographies each year. In 2012, the organized screening participation rate was 52.7%, well below the European target of 70%. Solutions must be found to increase this rate to recommended target levels. Three French departments have developed mobile mammography screening programmes, but their participation rates are not higher than the national average and they are associated with a number of obstacles, notably financial and technical...

: 180 Background: Like other medical interventions, cancer screening requires shared decision-making (SDM). To better understand the process, we are performing a cluster-randomized trial of educational supports to improve screening guideline compliance for breast, cervical, colorectal, lung and prostate cancer at two urban academic medical centers. We present interim results that focus on recalled SDM discussions. METHODS: We are enrolling an age- and sex-stratified sample of 216 patients aged 30 to 89 years, 18 treated by each of 12 primary care physicians at two affiliated hospitals before a periodic physical examination...

: 184 Background: Prior studies have exploredbarriers to collaborative cancer care and suggest a need for greater clarity about clinician roles. However, little is known about patient's preferences and expectations for which clinicians handle various aspects of care after primary cancer treatment. METHODS: A weighted random sample of newly diagnosed breast cancer patients in the Georgia and Los Angeles SEER registries were surveyed approximately 6 months after diagnosis (expected final N = 2600, 70% current response rate)...

RATIONALE & OBJECTIVES: We sought to develop an abbreviated protocol (AP) for breast MRI that maximizes lesion detection by assessing each lesion not seen on mammography by each acquisition from a full diagnostic protocol (FDP). MATERIALS & METHODS: 671 asymptomatic women (mean 55.7 years, range 40-80) with a negative mammogram were prospectively enrolled in this IRB approved study. All lesions on MRI not visualized on mammography were analyzed, reported, and suspicious lesions biopsied...

REVIEW
Harris Carmichael, Cindy Matsen, Phoebe Freer, Wendy Kohlmann, Matthew Stein, Saundra S Buys, Sarah Colonna
Screening recommendations for women with BRCA mutations include annual breast MRI starting at age 25, with annual mammogram added at age 30. The median age of childbearing in the US is age 28, therefore many BRCA mutation carriers will be pregnant or breastfeeding during the time when intensive screening is most important to manage their increased breast cancer risk. Despite this critical overlap, there is little evidence to guide clinicians on the appropriate screening for women with BRCA mutations during pregnancy or breastfeeding...

BACKGROUND: The incidence of breast cancer in Asia is increasing because of urbanization and lifestyle changes. In the developing countries in Asia, women present at late stages, and mortality is high. Mammographic screening is the only evidence-based screening modality that reduces breast cancer mortality. To date, only opportunistic screening is offered in the majority of Asian countries because of the lack of justification and funding. Nevertheless, there have been few reports on the effectiveness of such programmes...

The purpose of this study was to evaluate the utility of a breast cancer risk assessment (BCRA) at the time of screening mammogram. Women whose BCRA indicated a high risk for cancer received a letter with instructions for breast health care and genetic counseling if appropriate. After 6 months this group received surveys to evaluate their risk perception and their recall of, and compliance with, recommendations. We also explored the impact of other variables such as a recommendation for genetic counseling and physician communication with the women...

OBJECTIVES: Compression is used in mammography to reduce breast thickness, which is claimed to improve image quality and reduce radiation dose. In the XXX Breast Cancer Screening Program (XBCSP), the recommended range of compression force for full field digital mammography is 11-18 kg (108-177 Newton [N]). This is the first study to investigate the compression force used in the program. METHODS: The study included information from 17,951 randomly selected women screened with FFDM at 14 breast centres in the XBCSP, January-March 2014...
