title: Clinicopathological characteristics of patients with extrahepatic recurrence following a hepatectomy for hepatocellular carcinoma.
abstract: OBJECTIVE
  None of the previous studies have compared the prognosis or clinicopathological factors between the patients with extrahepatic recurrence and those with intrahepatic recurrence of hepatocellular carcinoma after a hepatic resection.
  
  
  METHODS
  The clinicopathological features and prognoses of patients with extrahepatic recurrence after a curative hepatectomy for hepatocellular carcinoma were investigated.
  
  
  RESULTS
  Twenty-three patients with extrahepatic recurrence had more advanced-stage hepatocellular carcinoma at the primary operation compared to 186 patients with intrahepatic recurrence. After adjusting for tumor size, the prognosis of the 2 groups were comparable. However, among the patients with hepatocellular carcinoma exceeding 5 cm in diameter, the number of patients whose plasma levels of des-gamma-carboxy prothrombin was higher than 2.0 AU/mL in the patients with extrahepatic recurrence (62.5%) was significantly more (P < 0.05) than that in the patients with intrahepatic recurrence (20.0%). On the other hand, the prognosis of the 13 patients with extrahepatic recurrence alone was significantly better than in the 10 patients with both intrahepatic and extrahepatic recurrences. The prognoses of the 3 patients who underwent a surgical resection for isolated extrahepatic recurrence were markedly better than that of the remaining 10 patients only treated palliatively.
  
  
  CONCLUSIONS
  If patients have tumors exceeding 5 cm in diameter and their plasma levels of des-gamma-carboxy prothrombin are higher than 2.0 AU/mL, more careful follow-up examinations than usual may thus be necessary in order to detect extrahepatic recurrence as early as possible. Furthermore, a surgical resection for the isolated extrahepatic recurrence of hepatocellular carcinoma is also recommended to produce long-term survivors.
