Correlation between CK20 and DEFA5 positivity in blood and bone marrow samples, respectively, and survival for patients with esophageal carcinoma (EC). Detection of (A,C) CK20 and (B,D) DEFA5 in (A,B) blood and (C,D) bone marrow samples of EC patients was assessed by RT-PCR and correlated with overall survival by Kaplan–Meier analysis. On the vertical dotted line, the 5-year (60 months) overall survival is shown. The horizontal dotted line at the cumulative survival probability of 0.5 indicates the median survival. (BL: blood, BM: bone marrow, n.s.: not significant).
