EPCAM and neoplasm: In the univariate Cox analysis after adjusting for age and sex, we found a significant association between death and pN1 [2.7 (1.14–6.2); p = 0.022], percentage of lymph nodes positive for tumor localization [1.15 (1.003–1.33); p = 0.045], adjuvant CT/RT [0.15 (0.037–0.67); p = 0.56], % of ESA+CD24+CD44− cells [1.043 (1.001–1.087); p = 0.046], % of ESA−CD24+CD44− cells [1.036 (1.006–1.068); p = 0.02], and % of CD24+ cells [1.034 (1.011–1.057); p = 0.004].
