Abstract

Objective: To examine 5-year survival in esophageal cancer after MIE compared to OE.

Summary background data: MIE is becoming an increasingly common approach in the surgical treatment of esophageal cancer. A recent meta-analysis suggested 18% lower 5-year all-cause mortality after MIE compared to OE, but the quality of the included studies was limited.

Methods: Population-based cohort study including almost all patients who underwent elective esophagectomy for esophageal cancer in Sweden or Finland in 2010 to 2016, with follow-up until end of 2019. Cox regression was used to provide hazard ratios (HRs) with 95% confidence intervals (CIs) of all-cause 5-year mortality (main outcome) after MIE (hybrid or total) versus OE. Adjustments were made for age, sex, comorbidity, pathological tumor stage, histological tumor type, neoadjuvant chemo(radio)therapy, country, and annual hospital volume of esophagectomy.

Results: Among all 1264 patients, 470 (37.2%) underwent MIE and 794 (62.8%) underwent OE. MIE was associated with an 18% decreased risk of all-cause 5-year mortality, compared to OE [adjusted HR 0.82, 95% CI 0.67- 1.00 ( P = 0.048)]. The HR of all-cause 5-year mortality was seemingly lower after total MIE compared to OE (adjusted HR 0.77, 95% CI 0.60-0.98) than after hybrid MIE compared to OE (adjusted HR 0.87, 95% CI 0.68-1.11).

Conclusions: This bi-national study indicates that MIE is associated with a higher 5-year survival than OE in patients with esophageal cancer, and that the survival benefit is greater after total MIE than hybrid MIE.
