CCDC18 and breast cancer: The ROC curve analysis revealed SFN gene as a potential biomarker (AUC: 0.7222, p=0.0083), the LINC01343 gene as a good biomarker (AUC: 0.7951, p=0.0005) in discriminating BC patients from healthy individuals, and the CCDC18-AS1 gene as the strongest biomarker (AUC: 0.8958, p < 0.0001) (Figures 5(a)–5(c)).
