Glycemic Status and Prognosis of Patients with Squamous Cell Carcinoma of the Esophagus

Abstract

Background

The impact of glycemic status on esophageal squamous cell carcinoma (ESCC) prognosis is unclear.

Methods

A total of 623 patients who underwent curative subtotal esophagectomy for ESCC were evaluated. Diabetes was defined as a prior diagnosis of diabetes under treatment or newly diagnosed diabetes based on preoperative glycosylated hemoglobin (HbA1c) levels. Poor glycemic control was defined as HbA1c ≥ 7.0%, whereas good glycemic control was defined as HbA1c < 7.0%. The impact of glycemic status on long-term survival after esophagectomy was evaluated.

Results

Among the 623 patients, 64 (10.3%) had diabetes including 30 (4.8%) with poor glycemic control. Although diabetes did not influence patient survival, patients with poor glycemic control had worse overall and disease-specific survival compared with those with good glycemic control (P = 0.011 and 0.039, respectively). Comparing poor glycemic control with good glycemic control, the hazard ratios (HRs) for overall and disease-specific mortality were 1.91 (1.15–3.18) and 1.89 (1.02–3.49) in univariate analysis. After multivariate adjustment, poor glycemic control also had increased risk of overall and disease-specific mortality [HR 1.72 (95% CI 1.02–2.88) and 1.65 (95% CI 0.89–3.08), respectively]. Poor glycemic control did not increase the risk of overall or disease-specific mortality in patients with stages 0–II disease but significantly increased this risk in those with stages III–IV disease [HR 2.05 (1.14–3.69) and 1.95 (1.01–3.80), respectively].

Conclusions

Poor glycemic control is an independent risk factor for overall and disease-specific mortality after esophagectomy for advanced-stage ESCC.
