Role of surgical treatment for recurrent hepatocellular carcinoma after hepatic resection.

From 1978 to 1989, 164 patients underwent hepatic resection for hepatocellular carcinoma at our institution. The carcinoma was resected completely in 149 patients. Sixteen patients were excluded from this study because it was not known whether they were recurrent or disease free, or because death occurred as a result of surgical complications. Recurrent disease occurred in 48.1% of the remaining 133 patients. Fifty-seven patients had recurrent tumor only in the residual liver. A second hepatic resection was performed in 14 cases, 22 received intraarterial chemotherapy and/or arterial embolization without resection,a nd the remaining 21 received no anticancer therapy. The 5-year survival rate of patients who had a second resection was 92.0%. Recurrences in distant organs occurred in 14 patients, and the recurrent carcinoma was resected in five cases. Four of these 5 patients survived more than 3 years after the second surgery. Aggressive surgical resection of recurrent HCC, even for distant metastasis, is a viable approach, and may produce long-term survivors.

Effect of prostaglandin E1 on hepatic function after hepatectomy in patients with chronic liver disease.

We designed a clinical study to determine the effect of prostaglandin E1 (PGE1) on functional recovery of the liver after hepatectomy. Thirty-five patients with primary hepatic neoplasms accompanied by chronic liver disease were randomly divided into two groups: 13 patients received intravenous PGE1 at 0.06 micro g/kg per minute for 3 postoperative days (PGE1[+] group) and 22 patients did not (PGE1[-] group). All postoperative values of hepatic function tests were calculated as a ratio to each preoperative value. Significantly higher cholinesterase ratios were observed in the PGE1[+] group than in the PGE1[-] group 2 weeks postsurgery (P < 0.05). The alanine aminotransferase (ALT) ratios at 1 and 2 weeks postsurgery were 118% and 123% in the PGE1[+] group and 207% and 175% in the PGE1[-] group, respectively. The ratio of the maximum postoperative ALT level was 503% in the PGE1[+] group and 792% in the PGE1[-] group (P < 0.05). We concluded that PGE1 would have the effect of conditioning the postoperative ALT elevation and cholinesterase deterioration and that the patient's postoperative course might be more favorable with the use of PGE1.
