Background/Aims:
An early diffuse type in the pattern of the postoperative intrahepatic recurrence of hepatocellular carcinoma has been recognized. The purpose of this study was to elucidate risk factors for diffuse recurrence of hepatocellular carcinoma.
Methodology:
The subjects involved in the present study were 114 patients with hepatocellular carcinomas resected in Tenri Hospital during the past 12 years. Univariate analysis was used for retrospective determination of the factors related to diffuse recurrences after surgery in 10 cases among 114 patients.
Results:
The risk factors linked to diffuse recurrence were microscopical portal infiltration (P < 0.01), elevated alpha-fetoprotein (more than 1000 ng/mL) (P < 0.05), the absence of preoperative transcatheter arterial embolization (P < 0.01), and two or more segmentectomies of the liver (P < 0.01). Six of 10 patients with microscopical portal infiltration and elevated alpha-fetoprotein (more than 1000 ng/mL) had diffuse recurrence (P < 0.01). Six of 8 patients with two or more segmentectomies without preoperative TAE had diffuse recurrence (P < 0.01).
Conclusions:
When patients with the diagnosis of operable hepatocellular carcinoma have portal infiltration and elevated alpha-fetoprotein (more than 1000 ng/mL), two or more segmentectomies of the liver without preoperative transcatheter arterial embolization should be avoided.
