[Chemoembolization of primary hepatic carcinoma with portal vein tumor thrombus]

Forty cases of primary hepatic carcinoma(PHC) with portal vein tumor thrombus(PTT) underwent chemoembolization twice or more. The total effective rate was 67.5%. The survival rates of half, one, and three years were 75.0%, 12.5%, and 2.5% respectively after the treatment. The mean survival time was 9 months. The effective rate of the cases with the branch PTT was higher than other cases(P < 0.05). The influence caused by the average treatment interval had no significant difference(P > 0.05). It is suggested that (1) in case of controlling the applications, TAI + TAE is an effective therapy of PHC with PTT; (2) no matter where PTT is, an active management must be adopted; (3) the average treatment interval shall be decided according to conditions of the patients.
