High Expression of Nuclear Snail, but not Cytoplasmic Staining, Predicts Poor Survival in Nasopharyngeal Carcinoma

Background Transcription factor Snail has been shown to promote tumor progression and metastasis in various cancers. However, its clinical significance in nasopharyngeal carcinoma (NPC) is still scanty. We have explored the clinical significance of Snail expression and its association with patient outcome in NPC.
