BACKGROUND: The objective of the current study was to investigate both short- and long-term outcomes of patients undergoing curative-intent resection for intrahepatic cholangiocarcinoma (ICC) stratified by extent of hepatic resection relative to overall final pathological margin status. METHODS: One thousand twenty-three patients with ICC who underwent curative-intent resection were identified from a multi-institutional database. Demographic, clinicopathological, and operative data, as well as overall (OS) and recurrence-free survival (RFS) were compared among patients undergoing major and minor resection before and after propensity score matching. RESULTS: Overall, 608 (59.4%) patients underwent major hepatectomy, while 415 (40.6%) had a minor resection. Major hepatectomy was more frequently performed among patients who had large, multiple, and bilobar tumors. Roughly half of patients (n = 294, 48.4%) developed a postoperative complication following major hepatectomy versus only one fourth of patients (n = 113, 27.2%) after minor resection (p < 0.001). In the propensity model, patients who underwent major hepatectomy had an equivalent OS and RFS versus patients who had a minor hepatectomy (median OS, 38 vs. 37 months, p = 0.556; and median RFS, 20 vs. 18 months, p = 0.635). Patients undergoing major resection had comparable OS and RFS with wide surgical margin (≥10 and 5-9 mm), but improved RFS when surgical margin was narrow (1-4 mm) versus minor resection in the propensity model. In the Cox regression model, tumor characteristics and surgical margin were independently associated with long-term outcome. CONCLUSIONS: Major hepatectomy for ICC was not associated with an overall survival benefit, yet was associated with increased perioperative morbidity. Margin width, rather than the extent of resection, affected long-term outcomes. Radical parenchymal-sparing resection should be advocated if a margin clearance of ≥5 mm can be achieved.
