TAFA4 and cervical squamous cell carcinoma: Our previous study revealed that detection of FAM19A4 methylation was able to effectively distinguish cervical cancer and healthy cervical tissue (96.8% vs 8.7%,P < 0.05) at formalin-fixed and paraffin -embedded (FFPE) levels, suggesting that FAM19A4 could be a promising biomarker of cervical carcinoma, which is consistent with Steenbergen’s study [14], showing a significant difference in cervical squamous cell carcinoma and normal cervical tissue (91% vs 5%, P < 0.05).
