[Evaluation of advanced laryngeal cancer extension in clinical and pathomorphologic examination]

The method of choice in larynx cancer treatment is surgery. The radical surgical procedure must be based on the proper assessment of loco-regional tumor extenstion. The aim of the study was the estimation and comparison of immensity of larynx cancer during clinical, pathological and microscopic examination, as well as the defining of anatomical and functional conditions which impede laryngoscopy. 180 patients with larynx cancer treated surgically in the Department of Otolaryngology of the University School of Medical Sciences in Poznań and in the Otolaryngology Ward in Piła. In group of 123 patients total laryngectomy and in 57 patients partial laryngectomy was performed. To conduct the analysis of discrepancies between cT and pT as well as cT and mT assessment "big" and "small" immensity features were used. The big immensity was thought to be two-grade difference of locoregional advancement, the small one-one-grade. Discrepancies between cT, pT and mT were stated in transglottic tumors the most often and in multifocal-rarely. The biggest differences in cT, pT and mT assessment occurred in supraglottic tumor localisation. The high correlation between pT and mT local tumor extension assessment was observed.
