간문맥종양혈전증을 동반한 간세포암종에서 반복적인 간동맥 내 항암약물주입요법의 효과

Abstract

Background/Aims: The aim of this study is to elucidate the efficacy of repeated hepatic arterial infusion chemotherapy (HAIC) and different chemotherapeutic regimens for treating patients having advanced hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT). Methods: From Jan. 1999 and Dec. 2003, a total of 103 patients diagnosed as having HCC with PVTT, but without extrahepatic spreading, were enrolled in this study. They were stratified into two groups. Group I (67 patients) received intraarterial cisplatin (CDDP, 80㎎/㎡ for 2 hours on Day 1), Group Ⅱ (36 patients) received intraarterial CDDP (6080㎎/㎡ for 2 hours on Day 2) and 5-fluorouracil (5-FU, 50080㎎/㎡ for 5 hours on Day 1-3). They were scheduled to receive at least three consecutive courses of the HAIC at 1 month intervals. Results: Among the 66 patients who completed the protocol, one (2.5%) and seven (17.5%) patients of group Ⅰ, and one (3.8%) and four (15.4%) of group Ⅱ, exhibited complete and partial responses, respectively. The median survival period of all the patients was 6 months. Group Ⅱ showed a tendency to improve the median survival compared to group Ⅰ (8.5 vs 5.0 months, respectively, P=0.45). The most common adverse reaction was nausea (58.2%). However, an elevation of the total bilirubin level was more frequent in Group Ⅰ than in Group Ⅱ (61.3% vs 20.7%, respectively, P<0.05). Conclusions: Repeated HAIC using CDDP achieved favorable results in a few patients with HCC with PVTT, and additional 5-FU may be useful. (Korean J Hepatol 2005;11:268-274)
