[Indications for function-preserving surgery in locally disseminated squamous cell cancer of the oral mucosa and oropharynx].

Analysis of 113 typical (within the same anatomical area) surgeries has helped define the indications for such interventions in stage-III squamous cell carcinoma, of the moving part of the tongue and cheek first of all. Clinical indications are dissemination of the tumor within one anatomical area, exophytic or ulcerous form of its growth, a higher than 50 percent realization of the effect of previous conservative therapy, no regional metastases; morphologic indications include the presence of a clear-cut borderline, manifest lymphoplasmacytic reaction of the adjacent tissues.
