Detection of the early phase of esophageal cancer progression into lamina propria mucosae by the serum p53 antibody.

Eight years after surgical treatment for breast cancer, serum p53 antibody levels suddenly increased in a 67-year-old woman without recurrent signs of cancer. Early esophageal squamous cell carcinoma was detected by endoscopic screening. After endoscopic submucosal dissection was completed, serum p53 antibody levels decreased to be in the normal range. Serum p53 antibody monitoring can be helpful for early detection of not only recurrence of primary carcinoma but also development of metachronous carcinoma. This case is the first to monitor the changing titers of serum p53 antibody at the early phase of esophageal cancer progression into lamina propria mucosae until the disappearance of tumor cells.
