Yougui Wu

J Biopharm Stat 2021 Sep 21:1-11. Epub 2021 Sep 21.

Department of Epidemiology and Biostatistics, College of Public Health, University of South Florida, Tampa, Florida, USA.

Predictive values of a binary diagnostic test are often evaluated under a random sample design. When the disease is rare, however, such a design might not be as efficient as a nested case-control design where the cases are oversampled from a large existing cohort. Under a nested case-control design, direct proportion estimators of predictive values are biased because cases are oversampled. Read More

Mucin Neovascularization as a Diagnostic Aid to Distinguish Mucinous Carcinomas From Mucocele-like Lesions in Breast Core Needle Biopsies.

Am J Surg Pathol 2021 Sep 21. Epub 2021 Sep 21.

Department of Pathology, Beth Israel Deaconess Medical Center and Harvard Medical School Department of Pathology, Brigham and Women's Hospital and Harvard Medical School Breast Oncology Program, Dana-Farber/Brigham and Women's Cancer Center, Boston, MA.

The distinction between mucinous carcinomas (MCs) and mucocele-like lesions (MLLs), particularly those containing detached epithelial fragments, can be problematic in the limited samples afforded by breast core needle biopsies (CNBs). Neovascularization of mucin has been proposed as a criterion to distinguish MC from MLL, but its value in helping to categorize mucin-producing breast lesions in CNB has not been previously investigated. To address this, we evaluated mucin neovascularization on hematoxylin and eosin (H&E)-stained sections of 140 CNB containing mucin-producing breast lesions including 52 MC, 17 mucin-producing ductal carcinoma in situ (mDCIS), and 71 MLL.

Predicting the Effect of Variants of Unknown Significance in Molecular Tumor Boards with the VUS-Predict Pipeline.

Stud Health Technol Inform 2021 Sep;283:209-216

Dept. of Medical Bioinformatics, University Medical Center Göttingen, Germany.

Precision oncology utilizing molecular biomarkers for targeted therapies is one of the hopes to treat cancer. The availability of patient specific molecular profiling through next-generation sequencing, though, increases the amount of available data per patient to an extent that computational support is required to identify potential driver alterations for targeted therapies and rational decision-making in molecular tumor boards (MTBs). For some genetic variants evidence-based drug recommendations are available in public databases, but for the majority, the variants of unknown significance (VUS), this clinical information is missing.

Screening mammography mitigates breast cancer disparities through early detection of triple negative breast cancer.

Clin Imaging 2021 Aug 30;80:430-437. Epub 2021 Aug 30.

Weill Cornell Medicine, Department of Breast Surgery, 425 E. 61st St., 10th Floor, New York, NY 10065, USA. Electronic address:

Purpose: Screening mammography improves breast cancer survival through early detection, but Triple Negative Breast Cancer (TNBC) is more difficult to detect on mammography and has lower survival compared to non-TNBC, even when detected at early stages. TNBC is twice as common among African American (AA) compared to White American (WA) women, thereby contributing to the 40% higher breast cancer mortality rates observed in AA women. The role of screening mammography in addressing breast cancer disparities is therefore worthy of study. Read More
