Peritoneal implantation from hepatocellular carcinoma (HCC) after hepatic resection is infrequent, and information on risk factors and long-term survival of such patients is lacking. The clinicopathologic features and risk factors of 16 HCC patients after hepatic resection who developed peritoneal implantation from an HCC and the prognosis after surgical resection of these HCC implants were assessed. The clinical features of 16 HCC patients after hepatic resection undergoing resection of peritoneal HCC implants (P-HCC) from 1986 and 2000 were reviewed. The clinical features and outcomes of 195 HCC patients undergoing hepatectomy without recurrence (NR-HCC) were used for comparison. During 1986 and 2000 a total of 749 HCC patients underwent hepatic resection. Of these 749 patients, 465 (62.1%) had HCC recurrence after hepatic resection during the follow-up period (median 26 months). Of the 465 patients, 26 (5.6%) developed peritoneal implants, and 16 of them underwent resection. Multivariate logistic regression analysis revealed that a high α-fetoprotein (AFP) level and capsular invasion by the tumor cells may predispose posthepatectomy patients to peritoneal implantation from their HCCs. The overall survival of the P-HCC patients after peritoneal implant resection was similar to that of the NR-HCC patients. An elevated AFP level might be regarded as a significant prognostic factor for poor overall survival (p = 0.0577) after resection of peritoneal implants from HCCs. Peritoneal implantation occurs infrequently in posthepatectomy patients with an HCC. Elevated AFP values and capsule invasion by tumor cells may predispose posthepatectomy patients to peritoneal implantation from HCCs. Surgical resection of peritoneal implants from HCCs may prolong survival in selected patients. Elevated AFP levels may be regarded as a possibly significant prognostic factor for poor overall survival after resection of peritoneal HCC implants.
