Bottom Line: Patients with COCC ≤8.0 had a significantly better CSS than patients with COCC >8.0 (53.1% vs 15.3%, P<0.001).In addition, the area under the curve (AUC) was 0.722 for COCC, 0.645 for CRP, and 0.618 for CEA, indicating that COCC was superior to CRP or CEA for CSS prediction.We conclude that COCC was superior to CRP or CEA as a more precise prognostic factor in patients with ESCC.

ABSTRACT

Background: The prognostic value of inflammatory index in esophageal cancer (EC) has not been established. In the present study, therefore, we initially evaluated a novel prognostic system, named the COCC (COmbination of C-reactive protein [CRP] and carcinoembryonic antigen [CEA]), for making a prognosis in patients with esophageal squamous cell carcinoma (ESCC).

Methods: A total of 327 patients with ESCC between January 2006 and December 2008 were included in this retrospective study. The COCC was calculated by combined CRP and CEA according to the logistic equation. The Kaplan-Meier method was used to calculate the cancer-specific survival (CSS), and the difference was assessed by the log-rank test. Cox regression analyses were performed to evaluate the prognostic factors.

Results: In our study, COCC was defined as CRP +0.71 CEA according to the logistic equation. Receiver operating characteristic curves for CSS prediction were plotted to verify the optimum cutoff points for CRP, CEA, and COCC, which were 9.8 mg/L, 4.2 ng/mL, and 8.0, respectively. Patients with COCC ≤8.0 had a significantly better CSS than patients with COCC >8.0 (53.1% vs 15.3%, P<0.001). Multivariate analysis revealed that COCC was an independent prognostic factor in patients with ESCC (P=0.006). In addition, the area under the curve (AUC) was 0.722 for COCC, 0.645 for CRP, and 0.618 for CEA, indicating that COCC was superior to CRP or CEA for CSS prediction.

Conclusion: The COCC is an independent prognostic factor in patients with ESCC. We conclude that COCC was superior to CRP or CEA as a more precise prognostic factor in patients with ESCC.

Mentions: Patients with COCC ≤8.0 had a significantly better CSS than patients with COCC >8.0 (53.1% vs 15.3%, P<0.001) (Figure 5A). There were also significant differences in CSS regarding CRP (46.6% vs 15.4%, P<0.001, Figure 5B) and CEA (45.1% vs 20.2%, P=0.001, Figure 5C). To assess the confounding effect of COCC on T stage and N stage, we further stratified patients into different groups corresponding to T stage (T1–T2 and T3–T4a) and N stage (N0 and N1–N3). The predictive value of COCC was significant in patients with T1–T2 (P=0.010), T3–T4a (P<0.001), N0 (P<0.001), and N1–N3 (P<0.001) (Figure 6).
