Health‑related quality of life after gastrectomy, esophagectomy, and combined esophagogastrectomy for gastroesophageal junction adenocarcinoma

• BACKGROUND: The postoperative health-related quality of life (HRQOL) outcomes in patients with gastroesophageal junction (GEJ) adenocarcinoma after gastrectomy and esophagectomy are unclear. The aim was to evaluate HRQOL outcomes 6 months after extended total gastrectomy, subtotal esophagectomy, and combined esophagogastrectomy. METHODS: Patients who underwent surgery for GEJ adenocarcinoma of Siewert type 2 or 3 in 2001-2005 were identified from a nationwide Swedish prospective and population-based cohort. Three surgical strategies, i.e., gastrectomy, esophagectomy, or esophagogastrectomy, were analyzed in relationship to HRQOL measured at 6 months after surgery (main outcome). HRQOL was assessed using well-validated questionnaires for general (EORTC QLQ-C30) and esophageal cancer-specific (EORTC QLQ-OES18) symptoms. Mean score differences (MSD) and 95% confidence intervals (CI) were analyzed using ANCOVA and adjusted for age, sex, tumor stage, comorbidity, education level, hospital volume, and postoperative complications. MSDs > 10 were regarded as clinically relevant. RESULTS: Among 176 patients with complete information on HRQOL and covariates, none of the MSDs for HRQOL among the three surgery groups were clinically and statistically significant. MSDs comparing esophagectomy and gastrectomy showed no major differences in global quality of life (MSD, +8, 95% CI, 0 to +16), physical function (MSD, +2, 95% CI, -5 to +9), pain (MSD, -3, 95% CI, -12 to +7), or reflux (MSD, +5, 95% CI, -4 to +14). Also, complication rates and 5-year survival rates were similar comparing esophagectomy and gastrectomy. CONCLUSIONS: Extended total gastrectomy, subtotal esophagectomy, and combined esophagogastrectomy seemed to yield similar 6-month postoperative HRQOL outcomes for patients with GEJ adenocarcinoma.
