RECK mRNA expression is associated with a poor prognosis in patients with ESCC. (A) Kaplan-Meier analysis of survival after surgery according to the RECK mRNA expression level. The decreased expression of RECK (−∆∆Cq ≤0) was significantly correlated with a poor overall postoperative survival in ESCC patients. (B) The decreased expression of RECK (−∆Cq ≤-4.66) in tumor tissues was significantly correlated with a poor overall postoperative survival. -∆∆Cq, -(∆CqESCC - ∆CqNon-tumor); -∆Cq, -(CqESCC - Cqβ-actin); RECK, reversion-inducing cysteine-rich protein with kazal motif; ESCC, esophageal squamous cell carcinoma.
