ABSTRACT
The patient had elevated plasma PIVKA-II and serum AFP levels. However, no tumor was detected with an ultrasonography, angiography, abdominal computed tomography (CT), and magnetic resonance imaging (MR). Gastric endoscopic examination disclosed gastric cancer and then subtotal gastrectomy was done. Shortly after the surgery, both plasma PIVKA-II and serum AFP levels returned to each normal level. The extirpated tumor revealed histologically immature and mature cancer cells. It was pathologically diagnosed as IIc early cancer. The localization of PIVKA-II and AFP in gastric cancer cells was demonstrated by the immunostaining method using monoclonal antibody. Taken together, these results indicate that cancer cells may produce PIVKA-II or AFP in this patient.
