5 Department of Radiology, Massachusetts General Hospital, Boston, MA.

Objective: The objective of our study was to compare the supplemental cancer yield and performance of breast MRI in women at higher-than-average risk for breast cancer after negative 2D full-field digital mammography (FFDM) or negative digital breast tomosynthesis (DBT).

Materials And Methods: Retrospective review identified 4418 screening breast MRI examinations: 2291 were performed from January 2010 through January 2012 of patients with a negative FFDM examination in the 12 months before MRI (FFDM group), and 2127 were performed from January 2013 through January 2015 of patients with a negative DBT examination in the 12 months before MRI (DBT group). Screening indications included genetic predisposition, personal history of breast cancer or high-risk lesion, prior chest irradiation, family history, or other risk factors conferring a lifetime risk of greater than 20%.

Leveraging the variable natural history of ductal carcinoma in situ (DCIS) to select optimal therapy.

Breast Cancer Res Treat 2018 Dec 8. Epub 2018 Dec 8.

Department of Surgery, Brooklyn Breast Cancer Program of Maimonides Medical Center, 745 64th Street, Brooklyn, NY, 11220, USA.

Purpose: Ductal carcinoma in situ (DCIS) is a non-obligate precursor to invasive ductal carcinoma. The authors sought to discuss the evidence suggesting that not all DCIS will progress to invasive disease if left untreated.

Results: Four lines of evidence align to suggest that not all of this in-situ disease progresses to invasive cancer: its prevalence on screening mammography, studies of missed diagnoses, incidental findings in autopsy specimens, and large retrospective reviews of those treated with excision alone.

Robust Short-Lag Spatial Coherence Imaging of Breast Ultrasound Data: Initial Clinical Results.

IEEE Trans Ultrason Ferroelectr Freq Control 2018 Nov 27. Epub 2018 Nov 27.

Ultrasound is frequently used in conjunction with mammography in order to detect breast cancer as early as possible. However, due largely to the heterogeneity of breast tissue, ultrasound images are plagued with clutter that obstructs important diagnostic features. Short-lag spatial coherence (SLSC) imaging has proven to be effective at clutter reduction in noisy ultrasound images. Read More

Ellen Warner

Cancers (Basel) 2018 Nov 30;10(12). Epub 2018 Nov 30.

Sunnybrook Odette Cancer Centre, University of Toronto, Toronto, ON M4N 3M5, Canada.

Women with BRCA mutations, who choose to decline or defer risk-reducing mastectomy, require a highly sensitive breast screening regimen they can begin by age 25 or 30. Meta-analysis of multiple observational studies, in which both mammography and magnetic resonance imaging (MRI) were performed annually, demonstrated a combined sensitivity of 94% for MRI plus mammography compared to 39% for mammography alone. There was negligible benefit from adding screening ultrasound or clinical breast examination to the other two modalities. Read More

Method: The breast lesion regions were first segmented and depicted on FFDM images from 106 patients. In this work, 11 gray-level gap-length matrix texture features and 12 shape features were extracted form craniocaudal view and mediolateral oblique view, and then Student's t-test, Fisher-score and Relief-F were introduced to select features.

Agreement between digital breast tomosynthesis and pathologic tumour size for staging breast cancer, and comparison with standard mammography.

Breast 2018 Nov 10;43:59-66. Epub 2018 Nov 10.

Sydney School of Public Health, Sydney Medical School, Edward Ford Building (A27), The University of Sydney, NSW 2006, Australia.

Purpose: Tomosynthesis is proposed to improve breast cancer assessment and staging. We compared tomosynthesis and mammography in estimating the size of newly-diagnosed breast cancers.

Methods: All pathologically-confirmed cancers detected in the STORM-2 trial (90 cancers, 85 women) were retrospectively measured on tomosynthesis by two independent readers. Read More

Measurement of breast-tissue x-ray attenuation by spectral imaging: fresh and fixed normal and malignant tissue.

Phys Med Biol 2018 Nov 22;63(23):235003. Epub 2018 Nov 22.

Philips Research, Knarrarnäsgatan 7, 164 85 Kista, Sweden. Philips Health Systems, Mammography Solutions, Torshamnsgatan 30A, 164 40 Kista, Sweden. Author to whom any correspondence should be addressed.

Knowledge of x-ray attenuation is essential for developing and evaluating x-ray imaging technologies. In mammography, measurement of breast density, dose estimation, and differentiation between cysts and solid tumours are example applications requiring accurate data on tissue attenuation. Published attenuation data are, however, sparse and cover a relatively wide range. Read More

The Development and Validation of a Modesty Measure for Diverse Muslim Populations.

J Relig Health 2018 Nov 21. Epub 2018 Nov 21.

Section of General Medicine, Department of Medicine, The University of Chicago, Chicago, IL, USA.

This paper reports on the multi-phase development of an English-language modesty measure for use among Muslim populations. The process yielded a 10-item measure that has high levels of internal consistency reliability (Cronbach's α of 0.83), and has acceptable discriminant and predictive validity. Read More

Automatic Labeling of Special Diagnostic Mammography Views from Images and DICOM Headers.

J Digit Imaging 2018 Nov 21. Epub 2018 Nov 21.

Institute for Computational Health Sciences, University of California, San Francisco, 550 16th Street, San Francisco, CA, USA.

Applying state-of-the-art machine learning techniques to medical images requires a thorough selection and normalization of input data. One of such steps in digital mammography screening for breast cancer is the labeling and removal of special diagnostic views, in which diagnostic tools or magnification are applied to assist in assessment of suspicious initial findings. As a common task in medical informatics is prediction of disease and its stage, these special diagnostic views, which are only enriched among the cohort of diseased cases, will bias machine learning disease predictions.

Meta-analysis of upgrade rates in 3163 radial scars excised after needle core biopsy diagnosis.

Breast Cancer Res Treat 2018 Nov 20. Epub 2018 Nov 20.

Cancer Epidemiology and Population Health Research Group, University of South Australia, Adelaide, Australia.

Background: Since concurrent malignancy may be associated with radial scars (RS) in up to 45% of RS diagnosed on core biopsy, surgical excision is usually advised. Recent very low upgrade rates have caused a re-evaluation of the need for routine surgery. We aimed to find subsets of RS at such low risk of upgrade, as to render imaging surveillance a plausible alternative to surgery. Read More

Interobserver agreement in breast ultrasound categorization in the Mammography and Ultrasonography Study for Breast Cancer Screening Effectiveness (MUST-BE) trial: results of a preliminary study.

Ultrasonography 2018 Sep 22. Epub 2018 Sep 22.

National Cancer Control Institute, National Cancer Center, Goyang, Korea.

Purpose: The purpose of this study was to record and evaluate interobserver agreement as quality control for the modified categorization of screening breast ultrasound developed by the Alliance for Breast Cancer Screening in Korea (ABCS-K) for the Mammography and Ultrasonography Study for Breast Cancer Screening Effectiveness (MUST-BE) trial.

Methods: Eight breast radiologists with 4-16 years of experience participated in 2 rounds of quality control testing for the MUST-BE trial. Two investigators randomly selected 125 and 100 cases of breast lesions with different ratios of malignant and benign lesions. Read More

Purpose To compare breast cancer detection performance of radiologists reading mammographic examinations unaided versus supported by an artificial intelligence (AI) system. Materials and Methods An enriched retrospective, fully crossed, multireader, multicase, HIPAA-compliant study was performed. Screening digital mammographic examinations from 240 women (median age, 62 years; range, 39-89 years) performed between 2013 and 2017 were included. Read More

Milk intake and mammographic density in premenopausal women.

Breast Cancer Res Treat 2018 Nov 20. Epub 2018 Nov 20.

Division of Public Health Sciences, Department of Surgery, Washington University School of Medicine, Campus Box 8100, 660 South Euclid Ave, St. Louis, 63110, MO, USA.

Purpose: Mammographic density is a strong risk factor for breast cancer. Although diet is associated with breast cancer risk, there are limited studies linking adult diet, including milk intake, with mammographic density. Here, we investigate the association of milk intake with mammographic density in premenopausal women. Read More
