ABSTRACT
The epidermal growth factor receptor (EGFR), proliferating cell nuclear antigen (PCNA) and Ki-67 immunostaining in paraffin sections from 154 cases of laryngeal squamous cell carcinoma, 25 specimens of normal and hyperplastic laryngeal epithelium, and 21 preneoplastic lesions was examined. The difference of EGFR expression and PCNA score between laryngeal cancer and dysplastic lesions vs normal and hyperplastic epithelium was significant. There was significant difference in Ki-67 score between malignant vs premalignant lesions and normal and hyperplastic epithelium. There was significant correlation between PCNA score and histopathological grading of the tumour. The highest PCNA expression was detected in stage G3. Our findings have shown that PCNA and Ki-67 staining can be used as a marker of cell proliferative activity in laryngeal epithelial lesions. EGFR, PCNA and Ki-67 expression correlate with severity of laryngeal lesions. PCNA immunostaining can aid in estimating the histological grade of malignant lesions.
