Preventing futile surgery in Intrahepatic and Perihilar cholangiocarcinomas: Can we identify preoperative factors to improve patient selection and optimize outcomes?

Background: Intraoperative unresectability, postoperative deaths and early recurrences remain devastating futile events in the surgical management of Intrahepatic cholangiocarcinomas (iCCA) and Perihilar cholangiocarcinomas (pCCA). The present study aims to determine the preoperative predictors of futile surgery in cholangiocarcinomas.
Methods: Consecutive hepatectomies for iCCA and pCCA, between September 2010 and June 2022 were included. Futility of surgery was defined as either intraoperative unresectability, postoperative 30-day mortality or recurrence within six months of surgery. Multivariable logistic regression was used to identify predictors of futility.
Results: One hundred and fifty patients of iCCA and pCCA underwent surgery during the time period. Thirty-seven (38.1 %) out of 97 patients of iCCA and 25(47.16 %) out of 53 patients of pCCA underwent futile resection. The predictive factors of futile surgery for iCCA were tumour number (≥2) (OR, 9.705; 95%CI, 2.378-39.614; p = 0.002), serum aspartate transaminase (OR, 8.31; 95%CI, 2.796-24.703; p < 0.001) and serum CA-19.9 (>37 U/ml) (OR, 2.95; 95%CI, 1.051-8.283; p = 0.04). The predictive factors of futility for pCCA were lymph node involvement (OR, 7.636; 95%CI, 1.824-31.979; p = 0.005) and serum alkaline phosphatase (>562.5 U/L) (OR, 11.211; 95%CI, 1.752-71.750; p = 0.011).
Conclusion: Futile surgery was observed in over one third of our patients. Five strong preoperative predictors of futility were identified. Careful analysis of these factors may reduce futile surgical explorations.
