[Abstract]
Background
Recently, studies have shown that plasma D-dimer and serum albumin are prognostic markers for esophageal cancer. The purpose of this study was to evaluate a novel prognostic scoring system—DA score (combination of preoperative plasma D-dimer and serum albumin levels)—and analyze the association between survival of patients with esophageal squamous cell carcinoma (ESCC) and their Glasgow prognostic score.
Methods
In this retrospective study, preoperative biochemical markers and clinicopathologic factors in 260 ESCC patients treated with transthoracic esophagectomy were reviewed. According to receiver operating characteristic analysis, the cutoff values of D-dimer and albumin were defined as 0.5 μg/mL and 43.8 g/L, respectively. Patients with high D-dimer levels (≥0.5 μg/mL) and low albumin levels (<43.8 g/L) were assigned a score of 2, those with only one of the two abnormalities were assigned a score of 1, and those with neither of the two abnormalities were assigned a score of 0.
Results
ESCC patients with a DA score of 0, 1, and 2 numbered 55, 116, and 89, respectively. Survival analysis showed that patients with a DA score of 2 had lower overall survival (OS) rates than those with DA scores of 1 and 0 (37.1% vs. 52.6% and 76.4%, P < 0.001); similar findings were observed for disease-free survival (DFS) rates (32.6% vs. 44.8% and 67.3%, P < 0.001). In addition, the predictive value of the DA score was also significant in patients with stages I–IIA and stages IIB–IV ESCC. Multivariate Cox regression analyses indicated that hazard ratios (HRs) for predicting OS of patients with DA scores 1 and 2 were 2.25 (P = 0.010) and 3.14 (P < 0.001), respectively, compared with those with a DA score of 0, and HRs for predicting DFS of patients with DA scores of 1 and 2 were 1.86 (P = 0.023) and 2.68 (P < 0.001), respectively, compared with those with a DA scores of 0.
Conclusions
Our study suggests that preoperative DA scores are notably associated with postoperative survival of ESCC patients.
