AIM: Recent studies have reported that the albumin-to-globulin ratio (AGR) may be a useful inflammatory-nutritional biomarker to predict postoperative complications and poor prognosis in various types of patients with cancer. However, its prognostic value in patients with esophageal cancer is still unclear. We aimed to examine the utility of the AGR for predicting the short- and long-term outcomes in patients with esophageal cancer who underwent curative resection. PATIENTS AND METHODS: This was a retrospective cohort analysis reviewing the medical records of consecutive patients who underwent esophagectomy for clinical stage I to III esophageal cancer at Yokohama City University. A total of 105 patients were identified between 2005 and 2018. The overall survival (OS), recurrence-free survival (RFS), and postoperative complication rates were compared between patients with high AGR (>1.48) and those with low AGR (≤1.48) group. RESULTS: A total of 57 and 48 patients were classified into the high and low AGR groups, respectively. There was no significant difference between the two groups in the rate of overall postoperative complications of more than Clavien-Dindo grade 3 (50.9% vs. 54.2%, p=0.85). The long-term findings showed that 5-year OS and RFS rates were significantly better for the group with a high AGR (67.2% vs. 33.8%, p<0.001 and 51.6% vs. 28.5%, p=0.003, respectively). CONCLUSION: This study suggests that a low preoperative AGR is a risk factor for poor RFS and OS in patients who are planning to undergo curative surgery for esophageal cancer. AGR may be a useful biomarker for establishing treatment strategies to improve patients' survival.
