Soluble interleukin-2 receptor in serum of patients with esophageal carcinoma.
We measured serum levels of sIL-2R in 28 patients with squamous cell esophageal carcinoma and in 12 controls. Sera for presence of sIL-2R were examined using DAKO Interleukin-2-receptor (CD25) ELISA. The samples were analyzed for CEA and SCC by using IMx System (Abbot). The mean values of sIL-2R in esophageal carcinoma group were significantly increased in comparison with control group. Our results suggest that sIL-2R may be useful in monitoring and prognosis estimation of disease in esophageal carcinoma and could be a valuable addition to the current spectrum of cancer markers.
