Assessing Textbook Oncologic Outcomes in Distal Pancreatectomy for Pancreatic Adenocarcinoma: A National Cancer Database Study

Background: This study investigates textbook oncologic outcomes (TOO), a measurement operationally defined to produce a holistic measure of surgical success, with respect to patients diagnosed with pancreatic adenocarcinoma undergoing distal (left) pancreatectomy for pancreatic adenocarcinoma. This study aims to identify factors associated with achieving TOO, emphasizing the role of hospital type. Methods: The NCDB (2010–2022) was queried for patients with clinical stage I–III pancreatic adenocarcinoma. Inclusion criteria consisted of patients > 18 who underwent curative partial or total pancreatectomy. The primary outcome was the achievement of TOO—operationally defined as R0 resection, ≥12 lymph nodes examined, no prolonged hospital stay, absence of 30-day mortality, and no readmissions. Logistic regression analyses were conducted to identify predictors of TOO. Results: Analysis of 11,194 patients showed that 38.9% achieved TOO. Achievement of TOO was associated with a median increase in one year in overall survival. Factors associated with TOO achievements in the adjusted model include female sex, private insurance, a lower Charlson/Deyo score, minimally invasive surgery (MIS), and high-volume centers. Notably, MIS emerged as a significant factor associated with 26% higher TOO (OR 1.26, 95% CI: 1.14–1.40) while treatment at high-volume hospitals was associated with 28–112% increased TOO (OR 1.28, 95% CI: 1.08–1.54 for Q3 volume and OR 2.12, 95% CI: 1.76–2.55 for Q4 volume). Conclusions: Achieving TOO is significantly influenced by patient demographics, clinical characteristics, and notably, the case volume of the treatment facility. These findings underscore the importance of considering centers experienced in surgical planning and patient counseling to optimize outcomes in distal pancreatectomies.
