Objective To explore the prognostic value of miR-196 a in esophageal carcinoma and its regulatory mechanism of biological behavior. Methods Esophageal carcinoma tissues and paracancerous tissues were collected from 120 patients. miR-196 a expression level was detected by RT-PCR. The relationships between miR-196 a expression and clinical data were analyzed. The esophageal carcinoma patients were followed up. The overall survival(OS) and disease-free survival(DFS) were recorded. Taking OS and DFS as evaluati...
