Double cancer of the stomach, one AFP-producing tumor.

In recent years, many cases of alpha-fetoprotein-producing gastric cancer (AFPGC) characterized by increased serum levels of alpha-fetoprotein (AFP) and AFP positivity of the gastric cancer have been reported. Here we present a case of AFPGC coexistent with a different histological type of gastric cancer: The AFPGC was Borrmann type 1 advanced gastric cancer with multiple liver metastasis and appeared to produce both AFP and des-gamma-carboxy prothrombin (PIVKA-II). The second cancer was IIc type early gastric cancer and did not produce AFP. Despite receiving palliative chemotherapy, the patient died, due to hepatic failure, 45 days after admission.
