[Attempt at the evaluation of stromal reactions in orofacial tumors]. / Pokus o hodnocení stromální reakce v nádorech orofaciální oblasti.

A group of 130 patients with malignant tumours of the orofacial region were examined. Each patient was investigated for tumour tissue stromal reaction in terms of topography, quantity and quality of the infiltrate, and with a view to the presence of necrosis. A comprehensive analysis found no direct correlation between stromal reaction and the patients' survival times.

Cellular reaction to autologous tumor tissue followed by "skin window" technique in orofacial tumors.

In a sample of patients with pseudotumors and benign and malignant tumors of the orofacial region there has repeatedly been investigated, after radical surgery, the cell reaction to autologous tumor tissue applied at indicated time intervals on a small skin lesion. The prognostically favorable picture of a cellular-type hypersensitivity reaction with massive participation of lymphoid cells and basophil granulocytes was only found in some basaliomas and leukoplakias. Conversely, spinocellular carcinomas are, irrespective of localization, characterized by areactivity.
