Perioperative and Long-Term Outcome for Intrahepatic Cholangiocarcinoma: Impact of Major Versus Minor Hepatectomy.

Journal Article (Journal Article)


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.


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.


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.


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.
