title: p53, PCNA and Ki67 in laryngeal cancer.
abstract: Immunohistopathological staining for p53, PCNA and Ki67 was performed in 120 specimens from previously untreated laryngeal carcinomas using the avidin-biotin method with peroxidase as a marker enzyme and diaminobenzidine as a chromogen. A 5-grade staining score system was used. Statistically significant correlations (Chi-square) were seen between T- and N-stage and histopathological grading. p53 and Ki67 scoring correlated with T- and N-stage whereas PCNA with T-stage. All staining correlated with histopathological grading. The score of staining for p53, PCNA and Ki67 correlated with each other. The patients with recurrences within 3 years had mainly carcinomas with higher staining scores. Using Chi-square analysis the p53, PCNA and Ki67 staining scores were also independent prognostic indicators.
