EGFR and carcinoma: The area under the curve (AUC) of FN1 expression was 0.875 (Figure 2C), higher than that of epidermal growth factor receptor (EGFR) expression (AUC = 0.756, p < 0.001), which has been regarded as a biomarker in multiple malignant carcinomas (Yip et al., 2017; Serilmez et al., 2019; Park et al., 2020).
