Background: The aim of this study was to develop a predictive model to identify individuals most likely to derive overall survival (OS) benefit from adjuvant chemotherapy (AC) after hepatic resection of intrahepatic cholangiocarcinoma (ICC). Methods: Patients who underwent hepatic resection of ICC between 1990 and 2020 were identified from a multi-institutional database. Factors associated with worse OS were identified and incorporated into an online predictive model to identify patients most likely to benefit from AC. Results: Among 726 patients, 189 (26.0%) individuals received AC. Factors associated with OS on multivariable analysis included CA19-9 (Hazard Ratio [HR]1.17, 95%CI 1.04–1.31), tumor burden score (HR1.09, 95%CI 1.04–1.15), T-category (T2/3/4, HR1.73, 95%CI 1.73–2.64), nodal disease (N1, HR3.80, 95%CI 2.02–7.15), tumor grade (HR1.88, 95%CI 1.00–3.55), and morphological subtype (HR2.19, 95%CI 1.08–4.46). A weighted predictive score was devised and made available online ( Receipt of AC was associated with a survival benefit among patients at high/medium-risk (high: no AC, 0% vs. AC, 20.6%; medium: no AC, 36.4% vs. 40.8%; both p < 0.05) but not low-risk (low: no AC, 65.1% vs. AC, 65.1%; p = 0.73) tumors. Conclusion: An online predictive model based on tumor characteristics may help identify which patients may benefit the most from AC following resection of ICC.
