Intracell Heat Shock Protein 70 Expression and Nasopharyngeal Carcinoma Stage.

Tumor growth and metastasis in nasopharyngeal carcinoma (NPC) patients recent research stated that intracellular Hsp70 is a stress protein as the main factor for the growth, invasion and metastasis of NPC. To analyze intracellular Hsp70 protein expression of NPC patients which correlate with staging of NPC as clinical manifestation. Formalin-fixed paraffin-embedded biopsy specimens from 20 NPCs histopathology and clinically.
