title: [The expression of nuclear proliferation antigen in oropharyngeal carcinoma].
abstract: Proliferating cell nuclear antigen (PCNA) is a nuclear protein synthesized in the late G1 and S phase of the cell cycle. Immunohistochemical detection of the protein is a useful marker of the proliferating cell fraction in tissue specimens. A series of 106 oropharyngeal carcinomas were evaluated using the streptavidin biotin immunoperoxidase method for detection of this protein. PCNA positivity ranged from 9 to 90.2% (mean: 54.86%; SD: 22.05). PCNA results did not correlate with clinical or histological parameters. Cox regression analysis confirmed the absence of statistical significance of the PCNA index in relation to overall survival.
