Neelima Vidula and her team evaluated the correlation between Trop2 gene expression and clinical and tumor characteristics in primary breast cancer (BC) using several databases, including I-SPY 1 (n = 149), METABRIC (n = 1992), TCGA (n = 817), and the full sample of the Kruskal-Wallis trial. Here, TACSTD2 is linked to breast carcinoma.
