The significance of DNA-RNA double parameter quantitative analysis in the early diagnosis of laryngeal squamous cell carcinoma / 第三军医大学学报

The relative content of DNA-RNA and the nuclear area/nucleolar area ratio of the hyperplastic tissue,glottic polypus,dysplastic tissue of grade I to I laryngeal squamous cell carcinoma were measured in 33 cases with image analysis technique.It was found that the changes of DNA-RNA content and the ratio of nuclear/nucleolar area were parallel to those of the severity of the carcinoma,and RNA was markedly increased in grade 11 and I dysplastic tissue.On the basis of the current grading of laryngeal pathology,the combined determination of DNA-RNA can provide more sensitive indicators to the stages of malignant degeneration of the laryngeal squamous cell carcinoma.
