Abstract

We present a case of multiple colorectal liver metastases with macroscopic portal vein thrombi. A 55-year-old woman presented to us with rectosigmoid cancer and presented with two liver metastases. The tumor in the posterior sector was associated with invasion of first order branches of the portal vein. We performed low anterior resection, hepatic posterior sectorectomy and partial left anterior sectorectomy. Both the colorectal cancer and liver tumors exhibited histological characteristics of moderately differentiated adenocarcinoma with a substantial amount of mucin production. The liver metastases were associated with prominent tumor thrombi in many branches of the portal vein. Stronger staining for endoglin (CD 105) than for Fas ligand (Fas L) and matrix metalloproteinase (MMP-2) was observed in both the colorectal cancer and metastatic liver tumor cells. Expression of the vascular endothelial growth factor within the tumor cells was seen in both the colorectal cancer as well as the metastatic liver tumor cells. Six months after the operation, she was diagnosed to have multiple, more than about 20 liver metastases, and in 9 months after the operation, the patient died. The colorectal cancer with liver metastases associated with portal vein tumor thrombosis was poor prognosis, found neoplastic microvessel formation.
