TACSTD2 and cervical cancer: The results showed that TROP2 was highly expressed in cervical cancer tissues (88.7%), but relatively low expression was found in normal (45%) and CIN tissues (64.7%) (P<0.001), and the percentage of TROP2 - positive cells increased progressively from CINI to CINIII, suggesting that TROP2 protein expression was significantly associated with the cervical oncogenesis and the development of cervical cancer.
