Preoperative Chemolipiodolization of the Whole Liver for Hepatocellular Carcinoma

Abstract

Background: Preoperative transarterial chemo-embolization is not routinely recommended before hepatectomy for resectable hepatocellular carcinoma. This study evaluated the effect of preoperative whole-liver chemolipiodolization. Patients and Methods: A retrospective comparison of background characteristics, operative results and long-term outcome was performed between 36 patients with chemolipiodolization confined to the tumor (selective group) and 23 patients with chemolipiodolization also involving the noncancerous liver (whole-liver group). Results: There were no serious side-effects in either group and the operative outcome did not differ between the two groups. Tumor diameter was significantly greater in the selective group, but other pathological characteristics were comparable. The 5-year disease-free and overall survival rates for the selective and whole-liver groups were 11.9% and 33.0% (p=0.0191) and 44.9% and 73.2% (p=0.0121), respectively. Conclusion: These results indicate that preoperative whole-liver chemolipiodolization reduces postoperative recurrence and prolongs survival in patients undergoing resection of hepatocellular carcinoma.
