Indications for Palliative Reduction Surgery for Hepatocellular Carcinoma with Multiple Intrahepatic Metastases

We evaluated the efficacy of and the indications for palliative reduction surgery as a procedure to improve the prognosis of hepatocellular carcinoma (HCC) patients with multiple intrahepatic metastases. From January 1986 to October 1997, 25 HCC patients with multiple intrahepatic metastases who underwent necessary palliative reduction surgery due to advanced disease, were participated in the study. The 1-, 3-, 5-year survival rates of 25 patients with reduction surgery were 54.7%, 29.9%, 22.4%, respectively. Moreover, the 1-, 3-, 5-year survival rates of patients with some postoperative supplemental treatment were 68.8%, 41.2% and 30.9%, respectively. All 6 patients who had been alive for more than 3 years had had primary tumors with diametric sizes of approximately 5 cm and had undergone, at most, one segmentectomy. These patients received postoperative supplemental treatments. The indication for palliative reduction surgery for HCC patients with multiple intrahepatic metastases was patients with a relatively small primary tumor (around 5 cm) which could be removed by one segmentectomy or less.
