Abstract

DNA content was measured by flow-cytometric analysis in 30 paraffin embedded sections from patients with laryngeal squamous cell carcinoma. The morphological characteristics and N staging of the tumours as registered in their clinical charts were correlated with their DNA content. Eighty per cent of the tumours were found to have a predominantly aneuploid distribution of DNA values. There was no correlation between the N stage of the tumour or degree of cell differentiation and DNA content. A multiploid pattern correlates with non-metastatic laryngeal tumours and we suggest that this pattern may be a good indicator for biological activity.
