(2018) reviewed 322 cases of cervical cancer and found that it is hard to diagnose GAS by preoperative biopsy, but some specific clinical manifestations, such as aqueous secretion and lower abdominal pain, high serum CA19-9 level, and immunohistochemistry (HIK1083 and MUC6 staining), often help the diagnosis. Here, MUC6 is linked to cervical cancer.
