title: Identification and clinical significance of circulating endothelial progenitor cells in gastric cancer.
abstract: BACKGROUND
  There are few reports of endothelial progenitor cells (EPCs) in peripheral blood have been found in patients with gastric cancer.
  
  
  OBJECTIVE
  We quantified EPCs in the peripheral blood of patients with gastric cancer, with the expectation that this approach might lead to a new marker for the diagnosis of gastric cancer.
  
  
  METHODS
  We enumerated CD34+/CD133+ EPCs in the peripheral blood of 145 subjects by use of flow cytometry.
  
  
  CONCLUSIONS
  The quantity of peripheral blood EPCs in patients with gastric cancer are correlated with patient's age. In addition, the number of peripheral blood EPCs in patients with gastric cancer increased with tumor node metastasis stage and histological differentiation of the cancers, and with the operative status of the patients.
