Two patients receiving hepatectomy for a metastatic liver tumor with portal vein tumor thrombus are reported. In case I a 28-year-old woman multiple metastases in the hepatic right lobe after oophorectomy for embryonal carcinoma of the ovary. A tumor thrombus involved the right portal vein down to its first branch. Extended right hepatic lobectomy was carried out, but she died of hepatic insufficiency due to a recurrent tumor in the residual liver two months after the operation. In cases 2 a 61-year-old man had a sigmoid colon carcinoma and a solitary metastatic deposit in the hepatic left lobe. A tumor trombus involved the left portal vein down to its first branch. Left hepatic lobectomy was carried out, but after 11 months he died of hepatic insufficiency due to massive metastases in the residual liver. Thus the prognosis for patients is poor despite hepatectomy including the tumorinvolved portal vein. More intensive therapeutic strategies are required to control cases of metastatic liver tumor with portal vein tumor thrombus.
