Abstract:
Objective To investigate the clinicopathological features of primary hepatocellular carcinoma of the liver(PCCCL)and assess the over-all survival rate of PCCCL after hepatectomy and the association between prognosis and clear cell ratio in PCCCL.Methods The clinicopathological data of 43 patients with PCCCL treated with hepatectomy in our hospital from January 1999 to December 2003 were retrospectively analyzed.Results X2 test showed a positive rate of HCV infection(14.0%)and capsule formation(88.4 0A)in the PCCCL group markedly higher than the positive rate of HCV infection(1.2%)and capsule formation(65.0%)in the CHCC group(P=0.000 and 0.005).Meanwhile,the vascular invasion rate was notably Iower in the PCCCL group(53.4%vs.65.0%),but there were no significant differences between the two groups(P=0.129).Kaplan-Meier method showed that the1-,3-and 5-year survival rates were significantly higher in the PCCCL group than in the CHCC group(81%,53%and 39%vs.76%,46%and 32 0A,P=0.021).The prognosis of patients in the PCCCL group was related to capsule formation.vascular invasion,liver cirrhosis and clear cell ratio.The 1-,3-and 5-year survival rates were markedly higher in the group with higher clear cell ratio (≥75%,subgroup B)than in group with lower clear cell ratio(＜75%,subgroup A)(80 0A,43%and 23%vs.85 0A,77% and 68%,P=0.011).Conclusion The notable clinicopathologicaI features of the patients with PCCCL are higher rates of HCV infection.capsule formation and lower rate of vascular invasion.Their prognosis is better than the patients with CHCC and related with the ratio of clear cell.
