Assessment of Liver Function for Evaluation of Long-Term Outcomes of Intrahepatic Cholangiocarcinoma: A Multi-Institutional Analysis of 620 Patients.

ABSTRACT: Background: Liver function is a routine laboratory test prior to curative liver resection. It remains unclear whether the albumin-bilirubin (ALBI) grade and albumin-to-alkaline phosphatase ratio (AAPR) can predict long-term outcomes of surgically treated patients with intrahepatic cholangiocarcinoma (ICC). Methods: This study investigated the correlation between ALBI grade and AAPR with overall survival (OS) after liver resection and then compared their accuracy to the Child-Pugh score. Harrell's concordance index (C-index) and Akaike information criterion (AIC) were used to compare accuracy of models. Results: A total of 620 ICC patients were included, 477 in derivation cohort and 143 for validation. 0.348 was identified as the cutoff value for AAPR after calculating the Youden index. In the derivation cohort, elevated ALBI grade was associated with worse prognosis [hazard ratio (HR): 1.751, 95% confidence interval (CI): 1.329 to 2.306], and a decreased AAPR value was correlated with shorter OS (HR: 1.969, 95% CI: 1.552 to 2.497). Multivariate analysis suggested that the ALBI grade, AAPR, CA19-9, tumor number, and microvascular invasion were independent prognostic predictors for OS. ALBI grade and AAPR showed more accuracy in evaluating OS for surgically treated ICC patients than the Child-Pugh score (C-index: 0.559, 0.600 vs. 0.528; AIC: 3023.84, 3007.73 vs. 3034.66). Our findings were validated in an independent cohort from another clinical center. Conclusions: Importantly, the ALBI grade and AAPR showed greater discriminatory power than the Child-Pugh score in assessing long-term outcomes following hepatectomy for ICC. The AAPR was more accurate than the ALBI grade. It was beneficial to consider the ALBI grade and AAPR as useful surrogate markers to identify patients at risk of poor postoperative outcomes.

Project description:ImportanceComposite measures may be superior to individual measures for the analysis of hospital performance and quality of surgical care.ObjectiveTo determine the incidence of a so-called textbook outcome, a composite measure of the quality of surgical care, among patients undergoing curative-intent resection of intrahepatic cholangiocarcinoma.Design, setting, and participantsThis cohort study involved an analysis of a multinational, multi-institutional cohort of patient from 15 major hepatobiliary centers in North America, Europe, Australia, and Asia who underwent curative-intent resection of intrahepatic cholangiocarcinoma between 1993 and 2015. Data analysis was conducted from April 2018 to May 2018.Main outcomes and measuresHospital variation in the composite end point of textbook outcome, defined as negative margins, no perioperative transfusion, no postoperative surgical complications, no prolonged length of stay, no 30-day readmissions, and no 30-day mortality. Secondary end points were factors associated with achieving textbook outcomes.ResultsAmong 687 patients (of whom 370 [53.9%] were men; median patient age, 61 [range, 18-86] years) undergoing curative-intent resection of intrahepatic cholangiocarcinoma, a textbook outcome was achieved in 175 patients (25.5%). Being 60 years or younger (odds ratio [OR], 1.61 [95% CI, 1.04-2.49]; P = .03), absence of preoperative jaundice (OR, 4.40 [95% CI, 1.28-15.15]; P = .02), no neoadjuvant chemotherapy (OR, 2.57 [95% CI, 1.05-6.29]; P = .04), T1a/T1b-stage disease (OR, 1.58 [95% CI, 1.01-2.49]; P = .049), N0 status (OR, 3.89 [95% CI, 1.77-8.54]; P = .001), and no bile duct resection (OR, 2.46 [95% CI, 1.25-4.84]; P = .009) were independently associated with achieving a textbook outcome after resection. A prolonged length of stay had the greatest negative association with a textbook outcome. A nomogram to assess the probability of textbook outcome was developed and had good accuracy in both the training data set (area under the curve, 0.755) and validation data set (area under the curve, 0.763).Conclusions and relevanceIn this study, while hepatic resection for intrahepatic cholangiocarcinoma was performed with less than 5% mortality in specialized centers, a textbook outcome was achieved in only approximately 26% of patients. A textbook outcome may be useful for the reporting of patient-level hospital performance and hospital variation, leading to quality improvement efforts after resection of intrahepatic cholangiocarcinoma.

Project description:Transjugular intrahepatic portosystemic shunt (TIPS) is a procedure designed to treat portal hypertension. Hospital teaching status is an institutional factor found to be predictive of outcomes following several complex procedures; however, its impact on outcomes following TIPS is unknown. The aim of this study was to determine the association between hospital teaching status and long-term survival in patients with cirrhosis receiving TIPS. We performed a retrospective population-based cohort study using linked administrative health data from Ontario, Canada. Adult patients with cirrhosis who received TIPS between January 1, 1998, and December 31, 2016, with follow-up until December 31, 2017, were included. Hospital teaching status was defined based on hospital participation in the instruction of medical students and/or resident physicians. Liver transplant-free (LTF) survival was evaluated using Kaplan-Meier analysis, and overall survival was assessed using competing risks regression analysis, which accounted for hospital clustering. A total of 857 unique patients were included (mean age 57.1 years; 69.1% male). The TIPS procedures were performed in teaching hospitals (84.3%) as well as nonteaching hospitals (15.7%). Median LTF survival was more than twice as long for procedures performed in teaching hospitals compared to nonteaching hospitals (2.2 years versus 0.9 year, respectively; P < 0.001). After adjusting for confounders and clustering, hospital teaching status was not independently associated with mortality (nonteaching subdistribution hazard ratio [sHR], 1.32; 95% confidence interval [CI], 0.97-1.81; P = 0.08); however, annual hospital procedure volume was (per unit increase sHR, 0.96; 95% CI, 0.93-0.99; P = 0.003). Conclusion: Hospital procedure volume is associated with long-term survival following TIPS. These results further support the centralization of TIPS to high-volume hospitals to improve long-term outcomes in this population.
