Background: We investigated the relationship between the preoperative psychological state and the perioperative nutritional conditions of patients with esophageal cancer.
Methods: Seventy-three participants underwent operations for esophageal cancer in our hospital. Depressive state was evaluated using the Self-Rating Depression Scale (SDS). General quality of life (QOL) was assessed using the SF-8™, and the nutritional assessments were evaluated through anthropometric analysis, bioelectrical impedance analysis (BIA) and some biochemical assessments.
Results: In the preoperative stage, patients with higher SDS scores, representing a more depressive state, had low arm circumference, grip strength, serum albumin levels and prognostic nutritional index. Patients with higher SDS scores also had a tendency for a lower physical component summary, representing physical QOL by the Eight-Item Short Form Health Survey (SF-8™). At 3 months after surgery, patients with higher preoperative SDS scores had significantly lower body mass indexes (BMIs) and had a lower tendency of body fat masses. In the univariate and multivariate analyses on the recovery of BMI at 3 months after surgery, preoperative SDS score was the only independent risk factor (odd ratio (OR): 4.07, 95% confidence interval (CI): 1.15 - 14.35) in this study.
Conclusion: Preoperative depressive mood, as evaluated by the SDS, was the sole relevant factor for postoperative body weight recovery of patients with esophageal cancer. Preoperative depressive mood of patients with esophageal cancer might delay recovery from operation-related malnutrition. Some measures against preoperative depressive mood might be necessary for early recovery from postoperative malnutrition in patients with esophageal cancer.
