A comparison was performed of staining intensity of immunohistochemical proliferating antigens (p53, PCNA, Ki67), DNA flow cytometry and ultrastructure of the carcinoma cells in 120 cases of laryngeal cancer. Clinically very advanced tumors were in majority (T3 - 43%, T4 - 18%). A 5 graded scale was adapted to evaluate the level of immunohistochemical staining of the carcinoma cell nuclei. A positive staining was obtained in 70% for p53, 57% for Ki67 and in 80(2/3) for PCNA. 62% of the cases were DNA diploid and 38% DNA aneuploid. The DNA diploid carcinomas were accompanied by the enlargement of the cell nuclei, preserving of the nuclei's wide margins of heterochromatine, enlargement of the nuclear area and increase of the number of nuclei. In the aneuploid-polyploid cancer the nuclei had a substantial polymorphism with large cleaved nuclei and with significant variation in size, and with nuclear envelope. A frequent finding was euchromatization of chromatine. Dense chromatine appeared in the form of small clumps spread over the whole area of these irregular nuclei. Enlargement and activation of nucleoli occurred. There was a positive correlation (Chi-square) between T- and N-stage and immunohistochemical staining. There was also a positive correlation in staining intensity between p53, Ki67 and PCNA. There is also strong correlation between these markers of proliferative activity and the degree of aggressiveness of the tumour.
