Serum tumor markers in patients with cancer assist with establishing diagnosis, estimating prognosis, monitoring treatment, and detecting tumor recurrence. Changes in the p53 tumor suppressor gene are the most common genetic abnormalities in many different human malignancies. Several studies have demonstrated that serum p53 antibodies (S-p53Ab) comprise an early marker of malignant disease, a marker for treatment effects and a prognostic factor for patients with several types of tumors. We recently reported that S-p53Ab is useful for patients with gastric cancer. We describe a rare situation in which unusually high serum p53 antibodies helped to detect recurrent gastric cancer in the small intestine after gastrectomy. Further studies are required to gain a more precise understanding of the clinical impact of S-p53Ab titer monitoring in gastric cancer.
