title: [Ki67, p53 and cyclin D1 in the squamous cell carcinoma of head and neck].
abstract: The difficult cancer development and the insufficient knowledge of the biology of the existing cancers lead for the constant search for the new techniques of diagnosis. The aim of this study was to analyze the selected prognostic factors such as p53, Ki67 and cyclin D1 in patients with head and neck cancer in connection with histological differentiation (G), TNM classification and the clinical advancement of the disease (S). The material comprised of the tissue specimens from 32 patients with squamous cell carcinomas of head and neck, who underwent the primary surgery. The immunohistochemical study was performed with avidin-biothin method. A 5-point grading system was adopted to assess the level of the immunohistochemical staining of the carcinoma cells. Through our study we found a statistically significant correlation between the staining intensity of carcinoma cells for p53, Ki67, cyclin D1 and the TNM classification and the clinical advancement of the disease (S). Such correlation for the histological differentiation (G) has not been observed. We think that the immunohistochemical techniques may constitute an important supplement of evaluation of the malignancy in the squamous cell carcinomas of head and neck.
