Background and Aims: The therapeutic efficacy of transarterial chemoembolization (TACE) has not been evaluated in hepatocellular carcinoma (HCC) patients with extrahepatic metastasis. We investigated the efficacy of TACE with/without systemic chemotherapy (s‐chemo) in these patients.
Methods: We performed a survival analysis of consecutive HCC patients with extrahepatic metastasis, diagnosed at initial presentation according to treatment modality after stratification, using the Child–Pugh classification and intrahepatic HCC T stage, retrospectively.
Results: Between 2005 and 2007, 251 patients were newly diagnosed with HCC involving extrahepatic metastasis at our institution. Among those, 226 were classified as Child–Pugh A–B and the other 25, Child‐Pugh C. Within the Child–Pugh A–B group, repeated TACE or transarterial chemoinfusion (TACI) was performed with/without s‐chemo in 171 patients. Eight of 226 received s‐chemo alone, and 47, conservative management (CM) alone. The median survival time of patients treated with TACE/TACI with s‐chemo, TACE/TACI alone, and CM was 10, 5, and 2.9 months in patients classified as Child–Pugh A and T3‐stage HCC (TACE/TACI with s‐chemo vs CM, P = 0.0354; TACE/TACI alone vs CM, P = 0.0553) and 7.1, 2.6, and 1.6 months in Child–Pugh B and T3‐stage patients, respectively (TACE/TACI with s‐chemo vs CM, P = 0.0097; TACE/TACI alone vs CM, P < 0.0001). Individual treatment with TACE/TACI or sorafenib showed independent prognostic significance in the multivariate analysis.
Conclusion: Repeated TACE could show significant survival benefits in metastatic HCC patients with conserved liver function and intrahepatic HCC T3 stage. The survival data of our study could be used as a historical control for TACE monotherapy in future clinical trials evaluating combination treatments containing TACE in these patients.
