Abstract

To compare the efficacy of ultrasound-guided percutaneous acetic acid injection and segmental transcatheter arterial embolization for hypervascular small hepatocellular carcinoma. The prognosis of 40 patients with one to three angiographically hypervascular hepatocellular carcinoma smaller than 3 cm in diameter treated with either percutaneous acetic acid injection (25 patients) or transcatheter arterial embolization (15 patients) during the past 4.5 yr were analyzed retrospectively. After initial therapy, none of 25 patients treated with percutaneous acetic acid injection developed ascites, whereas 5 of 15 (33%) patients treated with transcatheter arterial embolization developed it (p < 0.01). All tumors became smaller once after each therapy. However, local recurrence (reenlargement of the original tumor) occurred in 1 of 29 (3%) tumors treated with percutaneous acetic acid injection and 11 of 22 (50%) tumors treated with transcatheter arterial embolization (p < 0.005). During the follow-up, 4 of 25 (16%) patients treated with percutaneous acetic acid injection and 10 of 15 (67%) patients treated with transcatheter arterial embolization died. The 1-, 2-, and 3-yr survival rate was 100, 94, and 83%, respectively, in patients t...Continue Reading
