ObjectiveIt was hypothesized that patient survival improves with increasing surgeon age up to an age where it then decreases.BackgroundExperience, physical and psychological abilities required for esophagectomy may change with increasing surgeon age.MethodsThis population-based cohort study included all patients having undergone esophagectomy for esophageal cancer in Sweden in 1987 to 2010, with follow-up until 2016. Risk-adjusted cumulative sum (RA-CUSUM) analysis was performed to estimate the relation between surgeon age and 90-day mortality, all-cause, and disease-specific 5-year mortality. Change-points in surgeon age identified by the RA-CUSUM were then analyzed in relation to mortality using multivariable Cox regression, providing hazard ratios (HRs) with 95% confidence intervals (CIs), adjusted for age, sex, comorbidity, tumor stage, tumor histology, neoadjuvant therapy, surgeon volume, and calendar year.ResultsAmong 139 surgeons performing 1761 esophagectomies, RA-CUSUM analysis of 90-day mortality showed change-points at 43 years (downward deflection) and at 56 years (upward deflection). Both all-cause and disease-specific 5-year mortality had corresponding change-points at 52 years and 56 years. Compared with surgeon age 52 to 55 years, surgeon age ≤51 years was associated with increased 90-day mortality (HR = 1.71, 95% CI 1.01-2.90) and 5-year all-cause mortality (HR = 1.21, 95% CI 1.02-1.43), and surgeon age ≥56 years showed increased 90-day mortality (HR = 2.38, 95% CI 1.38-4.13), 5-year all-cause mortality (HR = 1.29, 95% CI 1.08-1.55), and disease-specific 5-year mortality (HR = 1.18, 95% CI 1.01-1.42).ConclusionsSurgeon age ≤51 and ≥56 years may increase short- and long-term mortality after esophagectomy for cancer.
