Multislice Computed Tomography in the Diagnosis of the Oral Cavity and Tongue Cancer
Abstract
The aim: to determine if the multislice computed tomography is effective in detecting the oral cavity and tongue cancer.
Materials and methods. A data set from MSCT research study containing records from 243 patients aged between 19 and 89 has been analyzed. The data included personal records of two groups: 124 (51.0%) patients of the main group with the diagnosis “tongue and oral cavity cancer” and 119 (49.0%) patients the control group, receiving assessment and treatment at Oncology in-patient specialized clinic №1, during a period from 2012 to 2016 years. The findings were compared to information received from clinical, instrumental examination and morphological results.
Results. Some typical CT signs of tongue and oral cavity cancer are identified as following: the asymmetry of anatomical structures; tissue densities ranging +39 HU...+43 HU (min/max −13…+86 HU); obliteration of fatty layers; the postcontrast densities increasing on 36–47 HU (min/max +26…+68 HU); the presence of a hypodense contrast agent-avoiding area; signs of additional tissue; signs of local tissue defect. Similar calculations are made for the four signs of the greatest figures in complex resulting in 97.6% sensitivity, 99.2% specificity and 98.4% accuracy. The analysis of parametric data showed a direct dependency between the degree of lymph nodes involvement and the thickness and width of the tongue tumor.
Conclusion. The results of this study indicate a high diagnostic efficacy of MSCT in detecting cancer of different localization in the mouth and on the tongue, determining the area affected and the identification of local metastasis.
