Deep Learning Image Analysis of Benign Breast Disease to Identify Subsequent Risk of Breast Cancer

Abstract: Background New biomarkers of risk may improve breast cancer risk prediction. We developed a computational pathology method to segment benign breast disease (BBD) whole slide images (WSIs) into epithelium, fibrous stroma, and fat. We applied our method to the BBD breast cancer nested case-control study within the Nurses' Health Studies to assess whether computer-derived tissue composition or a morphometric signature was associated with subsequent risk of breast cancer. Methods Tissue segmentation and nuclei … Show more

“…We previously investigated the association of automated breast tissue composition and BC risk in the Nurses’ Health Studies (28). Women in the highest quartile for % epithelium had higher BC risk compared to women in the lowest quartile; there was no relationship between % fibrous stroma and BC risk (28). Taken together, this current study now provides quantitative histological evidence to support prior epidemiological reports that TT may reduce BC risk (35).…”

“…There was no relationship between TT and mammographic breast density. We previously investigated the association of automated breast tissue composition and BC risk in the Nurses' Health Studies (28). Women in the highest quartile for % epithelium had higher BC risk compared to women in the lowest quartile; there was no relationship between % fibrous stroma and BC risk (28).…”

“…We previously developed a deep-learning algorithm to segment breast histological images into epithelium, fibrous stroma, and fat [ 28 ]. As this algorithm was not developed using images containing nipple-areolar complex or skin, it was likely to erroneously classify pixels containing nipple-areolar complex or skin as breast epithelium.…”

“…We previously developed a computational pathology algorithm to assess non-cancer breast tissue composition [ 26 29 ]. Using our algorithm, women with more breast epithelium (highest quartile) had higher subsequent BC risk compared with women in the lowest quartile [ 28 ]. Hormone-related BC risk factors such as reproductive and early body weight were also linked to changes in breast tissue composition [ 26 , 27 ].…”
