Abstract

Aim: To define whether the patterns of intrahepatic recurrence after resection for hepatocellular carcinoma differ according to hepatitis viral status.

Methods: One hundred and eleven patients undergoing a curative resection for hepatocellular carcinoma were divided into three groups: the C-viral group (n=55), which tested positive for hepatitis C antibody; the B-viral group (n=32), which tested positive for hepatitis B surface antigen; and the non-B non-C (NBNC) group (n=24), which tested negative for both hepatitis B surface antigen and hepatitis C antibody. The long-term outcomes were analyzed retrospectively.

Results:The pattern of development of intrahepatic recurrence differed between the NBNC group and the other groups: the cumulative probability of intrahepatic recurrence reached a plateau at 2.4 years after resection in the NBNC group, while it continued to increase steadily in the hepatitis viral groups. The C-viral group showed a higher incidence of intrahepatic recurrence than the other groups by univariate (P=0.0306) and multivariate (relative risk=1.69, P=0.0429) analyses. Multiple intrahepatic recurrent lesions were more common in the C-viral group (P=0.0457).

Conclusions: Multicentric carcinogenesis in the remnant liver was less common in the NBNC group than in hepatitis viral groups. Hepatitis C virus infection is a significant risk factor for intrahepatic recurrence after resection and is also associated with multiple intrahepatic recurrent lesions.

      Previous observations21 suggest the possible mechanisms responsible for postresectional intrahepatic recurrence in HCC, such as intrahepatic metastases from the primary tumor and multicentric carcinogenesis in the remnant liver. Some reports21–23 have suggested that early recurrence (within 2 years after resection) can be attributed to both intrahepatic recurrence from the primary tumor and the multicentric lesions, whereas late recurrence (more than 2 years) is predominantly of multicentric origin. Assuming that the incidence of multicentric origin is constant with time, our observation implies that major resection reduces the incidence of intrahepatic metastasis from the primary tumor.

      Sixteen of the papers included a multivariate analysis for overall and/or disease-free survival [20,22,24,26,27,29,33,34,37–41,45,46,48,49]. The results of these multivariate analyses were examined together with data obtained from numerous additional series which did not fit the inclusion criteria of the main analysis but in which a multivariate analysis was performed for survival [50–84]. A number of risk factors have been frequently reported as being of importance in predicting a poor outcome following resection and these can be summarised into: patient-related; tumour/liver-related and procedure-related.
