[FCM detection and pathology observation of 5 mm cutting-edge of laryngocarcinoma].

Objective: To explore the safety of 5 mm cutting-edges with the analysis of DNA contend and cell cycle and the pathology observation.

Method: Twenty specimens of laryngocarcinoma and its cutting-edges were analyzed by flow cytometry, contrasting to 5 samples of normal larynx tissue, and their light-microscopy and electra-microscopy were discussed.

Result: The DNA aneuploidy(AN) rate in the laryngocarcinoma, its cutting-edges and the normal tissue is respectively 60% (12/20), 15%(3/20) and 0.
