Summary
This study developed an online calculator to predict very early recurrence (VER) in intrahepatic cholangiocarcinoma (ICC) patients after surgery. The tool aids clinicians in patient selection for neoadjuvant therapy and informs postoperative surveillance strategies.
Area of Science:
- Hepatobiliary surgery
- Surgical oncology
- Gastroenterology
Background:
- Intrahepatic cholangiocarcinoma (ICC) prognosis is poor due to high recurrence rates post-surgery.
- Surgery offers the best cure potential for resectable ICC, but predicting recurrence remains challenging.
Purpose of the Study:
- To develop predictive models for very early recurrence (VER) within 6 months after ICC resection.
- To create and validate an online calculator for predicting VER in pre- and postoperative settings.
Main Methods:
- Logistic regression models were built using pre- and postoperative variables from an international multi-institutional database of 880 ICC patients.
- Models were validated internally and externally, and an online calculator was developed.
Main Results:
- 22.3% of patients experienced VER, with significantly lower 5-year survival (8.9% vs. 49.8%).
- Both preoperative and postoperative models effectively stratified patients into low, intermediate, and high risk for VER.
- The online calculator demonstrated good predictive accuracy in validation datasets (C-index: 0.672-0.728).
Conclusions:
- An online calculator can accurately predict VER risk in ICC patients post-resection.
- This tool can assist in preoperative treatment decisions and postoperative surveillance planning.
- The calculator's validated performance supports its clinical utility for managing ICC.
