355 Predictors of Textbook Outcome Following Oesophagogastric Cancer Surgery: A Single-Centre Analysis

Abstract Aim Textbook outcome (TO) is a multidimensional composite measure representing an ideal perioperative course, which has been utilised to assess the quality of care in oesophagogastric cancer surgery. We aim to determine TO rates among oesophagogastric cancer patients in a UK tertiary centre, investigate predictors of TO attainment, and evaluate the relationship between TO and survival. Method A retrospective analysis of a prospectively collected departmental database between 2006-2021 was conducted. Patients that underwent radical oesophagogastric cancer surgery with curative intent were included. TO attainment required margin-negative resection, adequate lymphadenectomy, uncomplicated postoperative course, and no hospital readmission. Predictors of TO were investigated using multivariable logistic regression. The association between TO and survival was evaluated using Kaplan-Meier analysis and Cox regression modelling. Results 667 oesophageal cancer and 312 gastric cancer patients were included. TO was achieved in 35.1% of oesophagectomy patients and 51.3% of gastrectomy patients. Several factors were independently associated with a low likelihood of TO attainment: T3 stage (OR:0.41, 95% CI 0.22-0.79, p=0.008) and T4 stage (OR:0.26, 95% CI 0.08-0.72, p=0.013) in the oesophagectomy cohort and high BMI (OR:0.93, 95% CI 0.88-0.98, p=0.011) in the gastrectomy cohort. TO attainment was associated with greater overall survival in oesophagectomy and gastrectomy cohorts, however, it was not associated with recurrence-free survival in the gastrectomy cohort. Conclusions TO is a relevant multidimensional metric that can be utilised to compare surgical quality between centres and investigate patients at risk of TO failure. Enhancement of preoperative care measures can improve TO rates and subsequently, long-term survival.
