Inclusion criteria

Inclusion criteria: 1.Patients with primary esophageal cancer who underwent curative-intent esophagectomy at Hokkaido University Hospital between January 2010 and December 2024. 2.Patients with available preoperative laboratory and anthropometric data required for calculation of the Geriatric Nutritional Risk Index. 3.Patients with available preoperative CT images required for measurement of the psoas muscle index.

Design outcomes

Primary

Measure	Time frame
Overall survival, defined as the time from surgery to death from any cause or last follow-up. Survival status and date of death during follow-up were assessed using medical records.	—

Secondary

Measure	Time frame
Disease-free survival, defined as the time from surgery to recurrence, death, or last follow-up. Recurrence status and date of recurrence were assessed using medical records, imaging studies, and endoscopic findings. Short-term postoperative outcomes, including postoperative complications, severe complications, anastomotic leakage, pneumonia, reoperation, in-hospital mortality, and length of postoperative hospital stay, were also evaluated. Postoperative complications were graded according to the Clavien-Dindo classification, and severe complications were defined as grade IIIb or higher.	—
