High expression of Trop‐2 has been discovered in a variety of human epithelial tumors including cervical, uterine, and ovarian cancers and confers tumor cells with an increased ability to proliferate and migrate (Bignotti et al., 2012; Liu et al., 2013; Santin et al., 2004; Varughese et al., 2011b; Xu et al., 2017). This evidence concerns the gene TACSTD2 and ovarian carcinoma.
