Background:
Textbook oncologic outcome (TOO) serves as a composite, oncologic metric for surgical quality of care. We sought to evaluate variations in TOO among patients undergoing laparoscopic, robotic, and open surgery for intrahepatic (iCCA) and perihilar (pCCA) cholangiocarcinoma.
Methods:
Patients who underwent liver resection for iCCA and pCCA between 2010 and 2018 were identified from the National Cancer Database. Entropy balancing was performed for covariate balancing and multivariable regression was used to evaluate the association between surgical approach and TOO.
Results:
Among 5434 patients who underwent hepatic resection between 2010 and 2018, 3888 (71.6%) had iCCA, and 1546 (28.4%) had pCCA. TOO was achieved in 11.7% (n = 454), and 18.8% (n = 291) of patients with iCCA and pCCA, respectively. There was a difference in achievement of TOO relative to operative approach among patients with iCCA (robotic: 6.2% vs. laparoscopic: 8.1% vs. open: 12.5%; p = 0.002). After entropy balancing, patients with iCCA undergoing laparoscopic surgery had 32% reduced odds of achieving TOO (Ref: open surgery; laparoscopic, OR 0.68, 95%CI 0.49-0.93; p = 0.016; robotic, OR 0.69, 95%CI 0.34-1.39; p = 0.298).
Conclusions:
Usage of composite oncologic measures such as TOO may allow for a holistic assessment of different approaches to hepatic resection among patients with CCA.
