In addition, this study also found that the areas under the ROC curve of MAGE-A9 mRNA in lesion tissues and MAGE-A9 mRNA in PBMC for the diagnosis of cervical cancer were 0.925 and 0.900, respectively, and were positively correlated with serum SCC-Ag, CA-125, and CEA of patients, suggesting that the detection of MAGE-A9 mRNA may provide a reference for the early diagnosis and treatment of cervical cancer, which is worthy of further exploration. The gene discussed is CEACAM5; the disease is cervical cancer.
