Peritoneal seeding of hepatocellular carcinoma after ethanol injection therapy.
The tumor seeding due to percutaneous ethanol injection therapy has been considered to be a very rare complication. Four cases of peritoneal seeding of hepatocellular carcinoma following percutaneous ethanol injection therapy are presented here. All patients had been initially treated for hepatocellular carcinomas with percutaneous ethanol injection therapy. Between 5 and 20 months after the percutaneous ethanol injection therapy, peritoneal seeding tumors were detected and resected surgically. Three patients recurred in the liver and one patient recurred in the abdominal cavity. Two died of cancer and 2 are still alive. The incidence of seeding following percutaneous ethanol injection therapy should not be so rare as considered referring to that due to fine needle biopsy, therefore careful attentions should be paid during the follow-up of those patients after percutaneous ethanol injection therapy.
