Rationale: This exploratory study aimed to investigate the relationship between the psoas muscle volume index (PVI) at 6 months after esophagectomy and various preoperative factors in patients with thoracic esophageal cancer.

Methods: The study included 40 thoracic esophageal cancer patients (aged 20–79 years) who performed perioperative gum-chewing training (GCT) and received one-stage radical esophagectomy at Department of Gastrointestinal Surgery in Okayama University Hospital. Spearman’s rank correlation coefficient was used to evaluate association between the PVI at 6 months after esophagectomy and various preoperative factors. A multiple liner regression analysis was performed.

Results: Thirty-two patients completed GCT. Two patients with missing values ​​for PVI at 6 months after esophagectomy were excluded from the analysis. Preoperative age, tongue pressure, chewing ability and the number of days of GCT before surgery were associated with PVI at 6 months after esophagectomy (p < 0.1). In multiple liner regression analysis, preoperative tongue pressure (p = 0.033) and the number of days of preoperative GCT (p = 0.007) were significantly positively associated with PVI at 6 months after esophagectomy.

Conclusion: PVI at 6 months after esophagectomy was significantly associated with preoperative tongue pressure and the number of days of GCT in patients with thoracic esophageal cancer.
