Results

Among 158 eligible patients, 124 (78.5%) were working at 18 months. Older age and pathological stage III or more were associated with non-working at 18 months, whereas sedentary work and self-employment were associated with a lower risk of non-working. Postoperative appetite loss, financial difficulties (QLQ-C30), and 10% or more body weight loss at 6 months were associated with non-working status. Median time to first RTW was 30 and 70 days for gastric and esophageal cancers, respectively.

Baseline Characteristics

The median age was 65.5 years (range: 37-84 years), and 152 (96.2%) patients achieved R0 resection. Pathological stage III or more disease was observed in approximately 30% patients. Postoperative complications were observed in 45 (28.5%) patients. More than 90% of the patients underwent minimally invasive surgery. Preoperative retirement was observed in seven (4.4%) patients, 55 (34.8%) patients were self-employed, 54 (34.2%) were regular employees, and 96 (60.8%) worked in companies or offices with 50 or fewer employees.

Participant flow

Overall, 167 patients were initially enrolled in this study, following the exclusion of 5. Two patients were excluded because they withdrew before postoperative assessment. In addition, patients who lacked willingness to RTW preoperatively (n = 1) and those who had missing critical outcome data (n = 1) were excluded from the analysis. A total of 158 patients were finally included in the analysis.

Outcome measures

The primary endpoint in this study was the proportion of patients who were working at 18 months post-surgery.
Secondary endpoints were the proportion of employed patients 18 months post-surgery (including those on sick leave) and time to return-to-work.
