Breast Cancer Screening Using Tomosynthesis in Combination With Digital Mammography

TLDR
Addition of tomosynthesis to digital mammography was associated with a decrease in recall rate and an increase in cancer detection rate, and further studies are needed to assess the relationship to clinical outcomes.
Abstract
mammography + tomosynthesis; difference, 1.3 (95% CI, 0.4-2.1; P = .004); for cancer detection, 4.2 (95% CI, 3.8-4.7) with digital mammography vs 5.4 (95% CI, 4.9-6.0) with digital mammography + tomosynthesis; difference, 1.2 (95% CI, 0.8-1.6; P < .001); and for invasive cancer detection, 2.9 (95% CI, 2.5-3.2) with digital mammography vs 4.1 (95% CI, 3.7-4.5) with digital mammography + tomosynthesis; difference, 1.2 (95% CI, 0.8-1.6; P < .001). The in situ cancer detection rate was 1.4 (95% CI, 1.2-1.6) per 1000 screens with both methods. Adding tomosynthesis was associated with an increase in the positive predictive value for recall from 4.3% to 6.4% (difference, 2.1%; 95% CI, 1.7%-2.5%; P < .001) and for biopsy from 24.2% to 29.2% (difference, 5.0%; 95% CI, 3.0%-7.0%; P < .001). CONCLUSIONS AND RELEVANCE Addition of tomosynthesis to digital mammography was associated with a decrease in recall rate and an increase in cancer detection rate. Further studies are needed to assess the relationship to clinical outcomes.

Insulin vs Sulfonylureas for Second-Line Diabetes Treatment

TL;DR: In this paper, the authors compared insulin and sulfonylurea drugs for second-line diabetes treatment and found that insulin was associated with increased risk of a composite of nonfatal cardiovascular outcomes and all-cause mortality in patients with diabetes mellitus.

Auxiliary diagnosis of small tumor in mammography based on deep learning

TL;DR: The core idea of multi feature kernel hash, combined with a variety of features and deep kernel hash network framework, constructs a new multi feature based deep learning network, which can effectively express the image features of breast tumor, and complete the task of breast micro tumor detection with good performance.

Rethinking the ACR Appropriateness Criteria® Supplemental Breast Cancer Screening Based on Breast Density.

TL;DR: Weinstein et al. as discussed by the authors proposed a new ACR Appropriateness Criteria (ACR) for supplemental breast cancer screening based on breast density, which is the only supplemental screening examination considered "usually appropriate" for individuals with dense breast tissue.

Screening for Lung Cancer: U.S. Preventive Services Task Force Recommendation Statement

TL;DR: Although lung cancer screening is not an alternative to smoking cessation, the USPSTF found adequate evidence that annual screening for lung cancer with LDCT in a defined population of high-risk persons can prevent a substantial number of lung cancerrelated deaths.

Diagnostic Performance of Digital versus Film Mammography for Breast-Cancer Screening

TL;DR: The overall diagnostic accuracy of digital and film mammography as a means of screening for breast cancer is similar, but digital mammography is more accurate in women under the age of 50 years, women with radiographically dense breasts, and premenopausal or perimenopausal women.
