Ultrasound Examination in Cases of Tongue and Floor of the Mouth Cancer

The extent of locally advanced tongue cancer and the presence of metastases need to be determined for adequate treatment planning. The standard diagnostic process for these patients include CT and MRI. Purpose. The aim of the investigation was to determine the possibilities of ultrasound examination in patients with carcinoma of the tongue and of the floor of the mouth. Material and methods. 128 patients were examined, 92 (71.2%) male and (28.8%) female. Median age was 55 years. All patients in this group had a primary tumor size more than 15 mm in greatest dimension and the tumor was well differentiated on ultrasound examination. All patients underwent ultrasound examination in outpatient clinic in order to determine the primary tumor extent. The results of ultrasound examination were compared with MRI, morphological examination of the tumor. The majority of patients (124 (96.9%) had squamous cell carcinoma of tongueor floor of the mouth at morphology. Results. Ultrasound examination allow effective tumor determination in all patients, evaluate the extent of primary tumor to the lingual artery, sublingual artery, extent over the midline to the counterlateral part of the tongue in case of unilateral lesion. While comparing the US and MRI data of tumor size assessment a correlation was found, the correlation coefficient was 0.68. The information about the tumor extent gives an opportunity to perform more organ preserving surgery. Conclusion. Ultrasound examination assists in visualization of tongue and floor of the mouth tumors, determination of local extent, planning of surgical procedure.
