N2 - Background: Multifocal intrahepatic cholangiocarcinoma (ICC) has traditionally been treated with surgical resection when amenable. Intra-arterial therapy (IAT) for multifocal ICC has not been directly compared with surgical resection. Methods: A single-center, retrospective review of consecutive patients treated for multifocal ICC was conducted. Patients with distant metastases or treatment with systemic chemotherapy alone were excluded. Patients were divided into two groups: surgical resection versus IAT; IAT included transarterial chemoembolization (TACE), transarterial radioembolization (TARE), and hepatic arterial infusion (HAI) pump therapy. Subjects were also analyzed by surgical resection, TACE, and HAI pump therapy. Results: Overall, 116 patients with multifocal ICC were studied, 57 in the surgical resection group and 59 in the IAT group (TACE = 41, HAI pump = 16, TARE = 2). The IAT group was characterized by a higher incidence of bilobar disease (88.1% vs. 47.4%, p < 0.001), larger tumors (median 10.6 vs. 7.5 cm, p = 0.004), higher incidence of macrovascular invasion (44.1% vs. 24.6%, p = 0.027), and higher rate of nodal metastases (57.6% vs. 28.6%, p = 0.002). Median overall survival for surgical resection was 20 months versus 16 months for IAT (p = 0.627). Multivariate analysis found that macrovascular invasion [hazard ratio (HR) 2.52, 95% confidence interval (CI) 1.56–4.09] and non-receipt of systemic chemotherapy (HR 3.81, 95% CI 2.23–6.52) were independent poor prognostic risk factors. Surgical resection was not associated with a survival advantage over IAT on multivariate analysis (p = 0.242). Conclusion: Despite selection bias for use of surgical resection compared with IAT, no survival advantage was conferred in the treatment of multifocal ICC.
