Prognostic significance of CYFRA 21-1 in patients with esophageal squamous cell carcinoma



Prognostic significance of CYFRA 21-1 in patients with esophageal squamous cell carcinoma



Journal of the American College of Surgeons 196(4): 573-578



CYFRA 21-1 has been reported as a useful tumor marker for esophageal carcinoma, but little information was reported about the clinicopathologic importance of CYFRA 21-1. The aim of this study was to analyze the clinicopathologic and prognostic significance of preoperative CYFRA 21-1 in patients with esophageal squamous cell carcinoma. The CYFRA 21-1 levels were measured before surgery by enzyme-linked immunosorbent assays in 157 patients with primary esophageal squamous cell carcinomas using 3.5 ng/mL as the upper limit of normal. All patients underwent radical surgical procedures without any preoperative therapy. The association between the clinicopathologic factors assessed and the CYFRA 21-1 level was determined. The CYFRA 21-1 values were monitored after surgery in 45 available patients. The prognostic values were determined by multivariate analysis using Cox's proportional hazards model. Thirty-one of the 157 patients (19.7%) had high CYFRA 21-1 levels (> or =3.5 ng/mL). CYFRA 21-1 levels were significantly increased in patients with large tumors (> or =40 mm, p = 0.009), deep tumors (T2-T4, p = 0.003), and node-positive tumors (p = 0.003). CYFRA 21-1 levels significantly decreased after surgery (p < 0.001). A high CYFRA 21-1 level before surgery was an independent prognostic factor for survival (p = 0.043). A high CYFRA 21-1 level is associated with tumor progression and poor survival in patients with esophageal squamous cell carcinoma.
