Association between Textbook Outcomes of Liver Surgery and Overall Survival in Gallbladder Cancer Patients Treated...

This study investigated the relationship between textbook outcomes of liver surgery (TOLS) and overall survival (OS) in patients who underwent curative-intent resection of GBC.

Patients with GBC who underwent curative-intent resection between 2014 and 2021 were selected from 16 hospitals. Patients were divided into either the TOLS group or the non-TOLS group, according to whether TOLS were observed. Patients who died within 90 days of surgery were excluded prior to the survival analysis. Log-rank test was used to compare the difference in the OS rate between TOLS and non-TOLS groups. Univariate and multivariate analyses were performed using Cox regression analysis to identify factors independently associated with OS.

A total of 913 patients were selected, 565 (61.9%) exhibited TOLS. The 5-year OS rate in the TOLS group was significantly higher than that in the non-TOLS group (45.4% vs. 21.9%; p < 0.001). Multivariate Cox regression analysis confirmed TOLS, total bilirubin level >54 µmol/mL, carcinoembryonic antigen level >5 µg/mL, CA 19-9 level >37 U/L, poor differentiation, stages T2 and T3/4 according to the 8th edition AJCC T staging manual, N1 and N2 according to the 8th edition AJCC N staging manual, and adjuvant chemotherapy as independent risk factors that affect OS after curative-intent resection of GBC.

Among patients who undergo curative-intent resection of GBC, approximately 61.9% experience TOLS. TOLS are not only the optimal short-term outcome but also associated with long-term survival.
