Abstract
PURPOSE: The textbook outcome (TBO), a multidimensional indicator that reflects an optimal perioperative course, has emerged as a significant prognostic variable in surgical oncology. Our study aimed to assess the occurrence and determinants of TBO following minimally invasive esophagectomy (MIE) for cancer. METHODS: A total of 945 patients who had undergone MIE at two high-volume centers between 2008 and 2022 were analyzed. Multivariable logistic regression analysis was applied to identify the independent predictors of TBO. The potential selection bias associated with choosing between different MIE techniques-namely, robotic esophagectomy (RE) and video-assisted thoracoscopic esophagectomy (VATE)-was addressed by applying inverse probability of treatment weighting (IPTW). RESULTS: TBO was realized in 46.6% of cases (n = 440), correlating with markedly better overall and disease-free survival. Multivariable analysis showed that treatment with RE (odds ratio (OR) = 1.527; 95% confidence interval (CI) = 1.149-2.028) was associated with a higher likelihood of achieving TBO, whereas a Charlson Comorbidity Index (CCI) of 2 or higher showed an opposite association (CCI2: OR = 0.687, 95% CI = 0.483-0.977; CCI ≥ 3: OR = 0.604, 95% CI = 0.399-0.915). The advantage of RE in attaining a higher rate of TBO, compared to VATE, remained statistically significant after applying IPTW, with rates of 53.3% for RE and 42.2% for VATE. Notably, RE contributed to a greater probability of thorough lymph node dissection, resection with negative margins, and the avoidance of major complications. CONCLUSION: TBO was realized in 46.6% of the patients who underwent MIE for cancer. Patients with a lower CCI and those who received RE were more likely to achieve TBO.
