Hepatoid carcinoma of the stomach is a rare neoplasm (especially in western countries) characterized by high levels of serum alpha-fetoprotein (AFP), the presence of "hepatoid foci" inside the gastric tumor and poor prognosis, due to the earlier onset of liver metastases. We treated six patients for hepatoid carcinoma of the stomach between 1990 and 1997. The female to male ratio was 1:1, the average age was 71 (54-81) and the average AFP-level was 1160 ng/ml (603-1531). We performed 2 total gastrectomies, 2 subtotal gastrectomies and 2 gastro-jejunostomies (due to presence of liver metastases): in one case, the patient underwent a splenectomy as well. All the tumors showed the presence of "hepatoid foci" (the morphological feature is close to the hepatocellular carcinoma) and a positive immunoreactivity to AFP. The mean survival was 3 months: only one patient is still alive and disease-free (with a 52 months follow-up). After radical surgery, she underwent a chemotherapic treatment with cisplatin, epirubicin, 5-fluorouracil and l-leucovorin. We conclude that our series (the widest in Italy and one of most impressive in Europe) confirm the poor prognosis of this neoplasm, but we also want to underline that this tumor is not so "unusual" any more and it requires new types of treatment, like postoperative chemotherapy, besides surgery, to be fighted properly.
