Lymphovascular invasion (LVI) is a critical pathological feature in breast cancer, strongly associated with an increased risk of metastasis and poorer prognosis. However, manual detection of LVI is labor-intensive and prone to inter-observer variability. To address these challenges, this study explores the potential of Swin-Transformer, a state-of-the-art deep learning model, and GigaPath, a cutting-edge foundation model, for automating the detection of LVI in whole-slide images (WSIs) of breast cancer tissue. We trained the models on a dataset of 90 annotated Hematoxylin and Eosin (H&E)-stained breast cancer slides, achieving strong performance with a slide-level Area Under the Receiver Operating Characteristic (AUC) of 97%, a sensitivity of 79% with an average of 8 false positives (FPs) per slide using the best-performing model. The results underscore the potential of Swin-Transformer and GigaPath to enhance diagnostic accuracy and consistency in LVI detection.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
