Background
Textbook oncologic outcome (TOO) is a composite outcome measure realized when all desired short-term quality metrics are met after an oncologic operation. This study examined the incidence and impact of achieving a TOO among patients undergoing resection of gastric adenocarcinoma.
Methods
The 2004–2016 National Cancer Database was queried for patients who underwent curative gastrectomy. Textbook oncologic outcome was defined as having met five metrics: R0 resection, American Joint Committee on Cancer-compliant lymph node evaluation (n ≥ 15), no prolonged hospital stay (< 75th percentile by year), no 30-day readmission, and receipt of guideline-accordant systemic therapy.
Results
Of 34,688 patients identified, 8249 (23.8 %) achieved TOO. The patients for whom TOO was achieved were more likely to have traveled farther (p < 0.001) and received care in an academic (p < 0.001) or very high case-volume facility (p < 0.001). The TOO group had a significanty higher median overall survival (OS) than the non-TOO group (80.5 vs 35.3 months; p < 0.001). The Kaplan-Meier curve showed that at 12 months, the survival probability estimate was 92 % for the TOO group versus 77 % for the non-TOO group. At 60 months (long-term survival), survival probability estimates remained higher for the TOO group (57 % vs 38 %). The results of the multivariate Cox regression model found that TOO attainment was significantly associated with a reduced risk of death (hazard ratio, 0.82; p < 0.001).
Conclusion
The TOO measure is associated with improved OS and reduced risk of death after gastrectomy for gastric adenocarcinoma. Unfortunately, in this study, TOO was obtained in only 23.8 % of cases.
