[Four cases of successful multidisciplinary treatment for hepatocellular carcinoma with portal venous thrombus].

CASE 1: TAI and radiation therapy were performed for a lateral segment and tumor thrombus extended into the left portal branch. Then, we diagnosed a tumor thrombus that extended into the right portal branch and TAI and operation were performed. The patient died about 9 months after the diagnosis of tumor thrombus. CASE 2: An operation was performed for hepatoma involving the right lobe and the tumor thrombus extended into the right portal branch. TAI and TAE were performed for residual tumor. The patient died about 12 months after diagnosis of tumor thrombus. CASE 3: An operation was performed for hepatoma involving an anterior segment and tumor thrombus extended into the right portal branch. Then, TAI, TAE and PMCT were performed for residual tumor. The patient is alive for 33 months with recurrence after the diagnosis of tumor thrombus. CASE 4: An operation was performed for hepatoma involving a posterior segment and tumor thrombus extended into the right portal branch. For recurrent TAI and TAE, radiation therapy was performed. The patient is alive for 20 months without recurrence after the diagnosis of tumor thrombus.
