Des-gamma carboxy prothrombin (PIVKA-II) and alpha-fetoprotein producing gastric cancer with multiple liver metastases.

| Abstract |
We describe the case of an 87-year-old woman who presented to Tokyo Kousei Nenkin Hospital because of appetite loss and general fatigue. Multiple liver masses and Borrmann type 2 gastric tumor were detected. A clinical diagnosis of hepatocellular carcinoma and gastric cancer was made based on the patient's high levels of serum alpha-fetoprotein (AFP; 490 200 ng/mL) and protein induced by vitamin K absence or antagonist-II (PIVKA-II, 2284 mAU/mL). The patient's general condition worsened gradually and she died 42 days after admission. Autopsy revealed that the predominant histological structure of the gastric tumor was trabecular or sheet-like, although a tubular structure was also found. Venous invasion was prominent. Immunohistochemically, the tumor tissue was positive for AFP and a few tumor cells were positive for PIVKA-II. The histological appearance and immunohistochemical features of the hepatic tumors resembled that of the gastric tumor. This case was pathologically diagnosed as AFP- and PIVKA-II-producing gastric carcinoma with multiple liver metastases. When tumors are found in the stomach and liver and serum PIVKA-II level is abnormally high, the possibility of PIVKA-II-producing gastric cancer with liver metastasis should be considered, especially when hepatitis virus markers are negative and liver cirrhosis is not present.
