Multimodality management of hepatocellular carcinoma larger than 10 cm.
BACKGROUND
Hepatic resection for huge hepatocellular carcinoma (HCC) is challenging. The role of multimodality nonsurgical therapy for HCC larger than 10 cm is unclear.


METHODS
We retrospectively investigated 131 HCC patients with main tumors larger than 10 cm in diameter seen between October 1990 and October 2001. Fifty-six patients (group A) underwent hepatectomy and 75 patients (group B) underwent nonsurgical multidisciplinary therapy including hepatic arterial infusion, transcatheter arterial embolization, and percutaneous acetic acid injection.


RESULTS
Patients in group B were older, had lower serum albumin levels, and there were more patients with liver cirrhosis and great vessel invasion. Median survivals of group A and B patients were 17 months and 7 months, respectively (p < 0.001). But the 1-, 3-, 5-year survival rates in group B using 38 patients undergoing 3 or more sessions of nonsurgical treatment were not significantly worse than those for group A using 53 patients with followup (57.1%, 19.0%, 16.3% versus 60.7%, 24.5%, 24.5%, respectively). Group A patients had 37.7% and 71.7% recurrence rates at 6 and 12 months, respectively, after operation, and they had a significantly higher frequency of overall extrahepatic recurrence compared with group B patients (43.4% versus 18.7%, p = 0.005). In group B, only 3 of 35 patients younger than 60 years had tumor shrinkage after nonsurgical treatment modalities in comparison to 17 of 40 patients in the elderly group (p = 0.003). Younger patients had a significantly higher prevalence of hepatitis B surface antigen positivity (85.7% versus 47.5%) and infiltrating tumor growth pattern (74.3% versus 45.0%) compared with older patients.


CONCLUSIONS
Our study suggests that the advantage of hepatic resection in patients with huge HCC is marginal. An effective adjuvant therapy is needed to improve outcomes after hepatic resection. The experience in using nonsurgical treatment shows that the result is poor in young patients compared with that in elderly patients.
