title: Hepatocellular carcinoma confined to Couinaud segment VIII: experience with extensive or limited resection.
abstract: OBJECTIVE
  Surgical treatment of hepatocellular carcinoma (HCC) confined to Couinaud segment VIII has been regarded as difficult. This study evaluates surgical and oncological results after extensive or limited resection of the tumor(s).
  
  
  METHODS
  Of the 399 HCC patients that underwent hepatic resection, 36 patients had the tumor(s) confined to segment VIII. These 36 patients were divided into group 1 (extensive resection) (n=15) (three right hepatectomies, 12 anterior segmentectomies) and group 2 (limited resection) (n=21) (11 subsegmentectomies, 10 wedge resections). Data were collected prospectively and analyzed retrospectively.
  
  
  RESULTS
  Hospital mortality and morbidity were 0% and 20% in group 1, 9.5%, and 38% in group 2 (P>0.05). Group 1 patients had larger tumor (4.0cm vs. 2.8cm; P=0.01), heavier resected specimen (380g vs. 118g; P<0.01), and a higher incidence of wide surgical margin (> or =1cm) (67% vs. 29%; P=0.041) than those in group 2. The percentage of patients in whom the a-fetoprotein levels returned to the normal range after resection was higher in group 1 (75.0%, 6 of 8 patients) than in group 2 (26.7%, 4 of 15 patients) (P=0.037). The 1-, 3-, and 5-year disease-free survival in group 1 (93%, 79% and 52%) were significantly better than those of group 2 (67%, 38% and 22%) (P=0.021).
  
  
  CONCLUSIONS
  In selected patients, extensive resection of HCC located in segment VIII correlates with better survival.
