Pyrimidine nucleoside phosphorylase (PyNPase) converts 5'-deoxy-5-fluorouridine to 5'-fluorouracil, which exerts an anticancer effect before being catabolized by dihydropyrimidine dehydrogenase (DPD). Recently, PyNPase has been shown to be identical to a potent angiogenic factor, platelet-derived endothelial cell growth factor. We analyzed the concentration of PyNPase and DPD in 33 patients with esophageal squamous cell carcinoma in fresh-frozen samples by enzyme-linked immunosorbent assay. In addition, we evaluated the clinical significance and prognostic value of PyNPase expression in esophageal carcinoma. The PyNPase concentration of tumor tissue was statistically higher than that of normal tissue of the esophagus (248 +/- 146 U/mg protein vs 73 +/- 63 U/mg protein, P = 0.0001), whereas DPD showed no difference (90 +/- 62 U/mg protein vs 88 +/- 62 U/mg protein, P = 0.825). The ratio of PyNPase to DPD of tumor tissue was statistically higher than that of normal tissue of the esophagus (3.3 vs 0.95, P = 0.0001). There were no significant differences between the group with high tumor to normal tissue ratios of PyNPase concentration and the low-ratio group in terms of the tumor length, depth, lymph node metastasis, lymph vessel invasion, vascular invasion, stage and survival. In conclusion, 5'-deoxy-5-fluorouridine may be effective on esophageal carcinoma and PyNPase concentration in esophageal carcinoma may not be a useful prognostic marker for patients with esophageal squamous cell carcinoma.
