[Comparative study of histology and flow cytometry results obtained in 2 groups of laryngeal tumors, glottic and supraglottic, in T-1 stage].
We studied histophatological parameters and DNA content in 27 supraglottic and 37 glottic T-1 squamous cell carcinoma of the larynx. The DNA content was determined by the Hedley method in paraffin-embedded sections of formalin-fixed blocks in an EPICS Profile flow cytometer. We studied 14 histopathological parameters and only 3 were statistically different in both groups of tumors: Differentiation, infiltrative degree and mitoses. There weren't statistical differences in DNA content (DNA index and proliferation index).
