Textbook oncologic outcome in pancreaticoduodenectomy: Do regionalization efforts make sense?

ABSTRACT:

Background and objectives

Few empiric studies evaluate the effects of regionalization on pancreatic cancer care.

Methods

We queried the National Cancer Database to identify patients undergoing pancreaticoduodenectomy for clinical stage I/II pancreatic adenocarcinoma between 2006 and 2015. Facilities were categorized by annual pancreatectomy volume. Textbook oncologic outcome was defined as a margin negative resection, appropriate lymph node assessment, no prolonged hospitalization, no 30-day readmission, no 90-day mortality, and timely receipt of adjuvant chemotherapy. Multivariable regression adjusted for comorbid disease, pathologic stage, and facility characteristics was used to evaluate the relationship between facility volume and textbook outcome.

Results

Sixteen thousand six hundred and two patients underwent pancreaticoduodenectomy; 3566 (21.5%) had a textbook outcome. Operations performed at high volume centers increased each year (45.8% in 2006 to 64.2% in 2015, p < 0.001) as did textbook outcome rates (14.3%-26.2%, p < 0.001). Surgical volume was associated with textbook outcome. High volume centers demonstrated higher unadjusted rates of textbook outcome (25.4% vs. 11.8% p < 0.01) and increased adjusted odds of textbook outcome relative to low volume centers (odds ratio: 2.39, [2.02, 2.85], p < 0.001). Textbook outcome was associated with improved overall survival independent of volume.

Conclusions

Regionalization of care for pancreaticoduodenectomy to high volume centers is ongoing and is associated with improved quality of care.

Project description:BackgroundTextbook outcome (TO) is a composite outcome measure for surgical quality assessment. The aim of this study was to assess TO following laparoscopic pancreaticoduodenectomy (LPD), identify factors independently associated with achieving TO, and analyze hospital variations regarding the TO after case-mix adjustment.MethodsThis multicenter cohort study retrospectively analyzed 1029 consecutive patients undergoing LPD at 16 high-volume pancreatic centers in China from January 2010 to August 2016. The percentage of patients achieving TO was calculated. Preoperative and intraoperative variables were compared between the TO and non-TO groups. Multivariate logistic regression was performed to identify factors independently associated with achieving TO. Hospital variations regarding the TO were analyzed by the observed/expected TO ratio after case-mix adjustment. Differences in expected TO rates between different types of hospitals were analyzed using the one-way analysis of variance test.ResultsTO was achieved in 68.9% ( n =709) of 1029 patients undergoing LPD, ranging from 46.4 to 85.0% between different hospitals. Dilated pancreatic duct (>3 mm) was associated with the increased probability of achieving TO [odds ratio (OR): 1.564; P =0.001], whereas advanced age (≥75 years) and concomitant cardiovascular disease were associated with a lower likelihood of achieving TO (OR: 0.545; P =0.037 and OR: 0.614; P =0.006, respectively). The observed/expected TO ratio varied from 0.62 to 1.22 after case-mix adjustment between different hospitals, but no significant hospital variations were observed. Hospital volume, the surgeon's experience with open pancreaticoduodenectomy and minimally invasive surgery, and surpassing the LPD learning curve were significantly correlated with expected TO rates.ConclusionTO was achieved by less than 70% of patients following LPD. Dilated pancreatic ducts, advanced age, and concomitant cardiovascular disease were independently associated with achieving TO. No significant hospital variations were observed after case-mix adjustment.

Project description:Assessing the perioperative outcomes of pancreaticoduodenectomy (PD) based solely on individual complications is not comprehensive, and the association between perioperative outcomes and the long-term prognosis of individuals diagnosed with pancreatic ductal adenocarcinoma (PDAC) remains uncertain. Our study is designed to evaluate the impact of a novel composite indicator, textbook outcomes (TO), on the long-term prognosis of patients undergoing PD for PDAC. This study conducted a retrospective analysis of 139 patients who underwent PD for pathologically confirmed PDAC at our hospital between January 2018 and December 2021. After applying exclusion criteria, a total of 111 patients were included in the subsequent analysis. These patients were categorized into two groups: the non-TO group (n=42) and the TO group (n=69). The Kaplan-Meier survival curve was employed to describe the relationship between TO and disease-free survival (DFS) and overall survival (OS). Cox regression was employed to assess the impact of achieving TO on long-term survival. Logistic regression was employed to investigate the risk factors affecting the achievement of TO. Out of the 111 PDAC patients, 69 (62.2%) achieved TO following PD. The achievement of TO significantly improved the OS of PDAC patients [P=0.03; hazard ratio (HR) =0.60; 95% confidence interval (CI): 0.37-0.83]. Cox regression analysis indicated that achieving TO was a protective factor for OS (P=0.04; HR =4.08; 95% CI: 1.07-15.61). Logistic regression analysis indicated that high amylase in drainage fluid on the third day after surgery (>1,300 U/L) was detrimental to achieve TO [odds ratio (OR) =0.10; 95% CI: 0.02-0.58; P=0.01], longer surgery durations (≥6.25 hours) was detrimental to achieve TO (OR =0.19; 95% CI: 0.06-0.54; P=0.002), and soft pancreatic texture was detrimental to achieve TO (OR =0.31; 95% CI: 0.10-0.93, P=0.04). Achievement of TO significantly improves the OS of PDAC patients and has the potential to serve as a robust prognostic indicator. Looking ahead, it is highly necessary for TO to become a standard surgical quality control measure in hospitals.

Project description:ImportanceTextbook outcome (TO) is a composite measure that captures the most desirable surgical outcomes as a single indicator, yet to date TO has not been defined and assessed in the field of laparoscopic liver resection (LLR) and open liver resection (OLR).ObjectiveTo obtain international agreement on the definition of TO in liver surgery (TOLS) and to assess the incidence of TO in LLR and OLR in a large international multicenter database using a propensity-score matched analysis.Design, setting, and participantsPatients undergoing LLR or OLR for all liver diseases between January 2011 and October 2019 were analyzed using a large international multicenter liver surgical database. An international survey was conducted among all members of the European-African Hepato-Pancreato-Biliary Association (E-AHPBA) and International Hepato-Pancreato-Biliary Association (IHPBA) to reach agreement on the definition of TOLS. The rate of TOLS was assessed for LLR and OLR before and after propensity-score matching. Factors associated with achieving TOLS were investigated.Main outcomes and measuresTextbook outcome, with TOLS defined as the absence of intraoperative incidents of grade 2 or higher, postoperative bile leak grade B or C, severe postoperative complications, readmission within 30 days after discharge, in-hospital mortality, and the presence of R0 resection margin.ResultsA total of 8188 patients (4559 LLR; median age, 65 years [interquartile range, 55-73 years]; 2529 were male [55.8%] and 3629 OLR; median age, 64 years [interquartile range, 56-71 years]; 2204 were male [60.7%]) were included in the analysis of whom 69.1% achieved TOLS; 74.8% for LLR and 61.9% for OLR (P < .001). On multivariable analysis, American Society of Anesthesiologists grade III, previous abdominal surgery, histological diagnosis of colorectal liver metastases (odds ratio [OR], 0.656 [95% CI, 0.457-0.940]; P = .02), cholangiocarcinoma, non-CRLM, a tumor size of 30 mm or more, minor resection of posterior/superior segments (OR, 0.716 [95% CI, 0.577-0.887]; P = .002), anatomically major resection (OR, 0.579 [95% CI, 0.418-0.803]; P = .001), and nonanatomical resection (OR, 0.612 [95% CI, 0.476-0.788]; P < .001) were associated with a worse TOLS rate after LLR. For OLR, only histological diagnosis of cholangiocarcinoma (OR, 0.360 [95% CI, 0.214-0.607]; P < .001) and a tumor size of 30 mm or more (30-50 mm = OR, 0.718 [95% CI, 0.565-0.911]; P = .01; 50.1-100 mm = OR, 0.729 [95% CI, 0.554-0.960]; P = .02; >10 cm = OR, 0.550 [95% CI, 0.366-0.826]; P = .004) were associated with a worse TOLS rate.Conclusions and relevanceIn this multicenter study, TOLS was found to be a useful tool for assessing patient-level hospital performance and may have utility in optimizing patient outcomes after LLR and OLR.
