title: Analysis of ploidy status in progression of head and neck cancers by DNA image cytometry.
abstract: Eight cases of leukoplakia, 25 lingual cancers, 15 cancers of the floor of the oral cavity, 11 pharyngeal cancers and 14 lymph nodes with squamous cell cancer metastases were stained using the Feulgen method to evaluate the ploidy status and ploidy related parameters. All leukoplakias were euploid. Percentage of aneuploid cancers correlated with the grade of tumours. Significant differences between tumours with 3 different locations were not found. Metastatic carcinoma cells in lymph nodes had significantly more cells in S-phase as compared to primary tumours.
