In clinical practice, needle biopsy has emerged as a powerful tool in diagnosing numerous suspicious breast masses detected through medical imaging. However, a notable proportion of needle biopsies are negative and the disrupted tissue architectures lead to limited histological information, making the diagnostic tasks for pathologists repetitive and difficult. Herein, we develop a screening platform utilizing a three-dimensional histological electrophoresis (3DHE) device coupled with a data analysis algorithm to quickly and automatically (1) exclude negative samples and (2) flag suspicious regions, thereby optimizing the clinical pathology workload. The 3DHE technology is applied to separate the dye-labeled proteins within biopsy tissue sections along the z-direction, allowing for a selected protein combination that provides maximum contrast for cancer tissue identification. Meanwhile, the developed algorithm can automatically sort samples into the exclusion group and the pending group based on postelectrophoresis protein signals. We accurately diagnose all malignant needle biopsies in 34 breast cancer cases. Furthermore, by weighting algorithm filters, our platform successfully pre-excludes 81.8% of negative samples without generating any false negatives. Our platform can act as a potent supplementary tool for evaluating breast cancer needle biopsies, serving as a preliminary screening step before pathological analysis.
