64 patients with tonsillar tumour entered the study. Endoral ultrasonography was performed by probe UST-937 Convex 5 MHz. Endoral ultrasonography is very efficient in exact tumour localisation and correlation between endoral ultrasonography and intraoperative assessment of T tumor is statistically significant. Ultrasonography is sensitive in recognition of satellite lesions. In the case of planoepithelial cancer, malignant lymphoma and inflammatory process very characteristic features of tumor can be described.
Endoral ultrasonography is better then transcutaneous in tonsillar tumours diagnosis.
The study subjects were 40 oral and pharyngeal cancer patients with primary tumours diagnosed as squamous cell carcinoma. Aromatic DNA adducts were found in all studied tissues. The average levels of DNA adducts in tumour and non-tumour tissues were found higher than in leucocytes. Biopsies from pharynx contained higher levels of DNA adducts than from oral cavities. Confounding effect of tobacco smoking and alcohol consumption on DNA adducts level was observed but it has not reached statistical significance.
