VEGFA and breast cancer: When it came to separating patients with early‐stage BC from HCs, ROC analysis showed that miRNA‐373 had a moderate discriminative power (specificity = 76.7%; sensitivity = 70.0%; AUC = 0.839), whereas exosomal VEGF had an excellent discriminative capacity (specificity = 85.0%; sensitivity = 90.0%; AUC = 0.944) [114].
