In this population-based cohort study involving 1,647 patients undergoing gastrectomy for gastric adenocarcinoma, surgeon age ≥47 years was associated with worse 5-year all-cause mortality rates. Adjusted hazard ratios for surgeons aged 55+ were 1.21 (95% CI 1.04 to 1.41), and for those aged 47-54 were 1.16 (95% CI 0.99 to 1.36), compared with those aged ≤46 years. The associations became non-significant after adjusting for lymph node yield, resection margin status, and complications, suggesting these factors may mediate the impact of surgeon age on long-term survival.
