Abstract PDF: Surgical resection has been considered to be the best treatment for early-stage hepatocellular carcinoma (HCC). However, radiofrequency ablation (RFA) has been reported to be more effective than other local ablation treatments and transarterial chemoembolization (TACE) in achieving complete tumor necrosis. Recently, combined chemoembolization and RFA may improve both overall and recurrence-free survival rates in patients with early stage HCC. RFA have not been applied in cases of that tumors were non-visualization on ultrasonography, and located near by large vessels, main bile ducts, and major extra-hepatic organs. we found that tumor, which was not shown on ultrasonography before TACE, can be visible for several days just after TACE. We report the clinical course and complete necrosis of tumor in two cases of small HCC by TACE and consecutive RFA within a few days.

Metastatic HCC Developed in the Peritoneal Cavity after Hepatic Resection - A Case Diagnosed by PET: Yeon Seok Seo, Hyung Joon Yim, Jung Woo Choi, Yang Seok Chae, Won Hyeok Choi, So Young Kwin, Chang Hong Lee; Journal of the Korean Liver Cancer Study Group. 2006;6(1):77-82.

Abstract PDF: Positron emission tomography (PET) can detect tumor by estimation of glucose metabolism of tumor cells. We experienced the case of intraperitoneal metastatic hepatocelluar carcinoma (HCC) diagnosed by PET. 36 year-old male patient had undergone hepatic resection for HCC. In the course of postoperative follow up, AFP level had risen gradually. We checked the abdominal sonography, CT, and celiac angiography, but results were unrevealing. To investigate hidden metastatic tumor, PET was performed and small tumor on the side of spleen was detected. The tumor was removed by laparoscopic operation, and revealed as HCC. AFP level gradually returned to normal.
