Clinicopathological features of malignancy in hepatocellular carcinoma
Abstract
The clinicopathological features showing the malignancy of hepatocellular carcinoma were investigated by retrospectively analyzing the postoperative prognosis after hepatic resection. The long-term prognosis was strongly affected by the existence of portal tumor invasion or intrahepatic metastasis as indicated by the following results. The 3-year cumulative survival rates were 61% and 38% for patients in portal vein tumor invasion groups (Vp0 and Vp1 (P less than 0.05). No patients with Vp2 or Vp3 could survive beyond 3 years after hepatic resection. Similarly, patients with intrahepatic metastasis IM0 showed a better prognosis, compared to those with IM2 or IM3 (P less than 0.05). In addition, the grade of tumor cell anaplasia to some extent affected the prognosis, but not the tumor growth pattern at the tumor/non-tumor boundary. The tumor growth rate, estimated by the alpha-fetoprotein doubling time, was not connected with venous invasion or intrahepatic metastasis, but it became shorter at the time of a recurrence. It is concluded that, from the standpoint of a long-term prognosis, the pathological features showing malignancy appear in venous invasion and intrahepatic metastasis.
