Computed tomography and magnetic resonance features of carcinoma of the tongue
La Radiologia medica, 2004
Computed tomography (CT) and magnetic resonance (MR) imaging allow more accurate staging of the carcinoma of the tongue than the clinical examination alone. The complex anatomy and the tumour margins make the interpretation of CT and MR images challenging. The aim of this paper is to review the technique and semiotic criteria for CT and MR evaluation and staging of carcinoma of the tongue.
Imaging in benign and malignant mass lesions of the tongue
International Journal of Advances in Medicine, 2016
Oral cavity imaging and interpretation especially that of the tongue is a complex process due to its anatomy and overlapping pathologies. In this article we discuss a brief outline of the anatomy of tongue, optimum imaging techniques, CT and MRI imaging of benign and malignant pathologies of the tongue are described. METHODS Twenty nine patients with mass lesions in tongue were prospectively examined for a period of seven months ABSTRACT Background: The purpose of this study was to determine the value of CT or MR imaging in demonstrating benign, malignant, congenital and iatrogenic mass lesions of the tongue. Although the vast majority of tongue masses are squamous cell carcinomas, a variety of unusual lesions may affect the tongue. Thus the characteristics and extent of these unusual lesions may be recognized only on cross sectional CT or MR images. In this article we describe the imaging findings of the various lingual masses, provide radio-pathological correlation and discuss the role of CT and MRI in diagnostic work-up of these uncommon lesions in clinical practice. Methods: Twenty nine patients with mass lesions in tongue were prospectively examined for a period of seven months from March to October 2014 with CT or MR imaging after physical examination. The imaging protocol includes contrast enhanced axial, coronal and sagittal images acquired with 64 slice GE VCT. MR imaging protocol includes three plane contrast-enhanced and non-contrast-enhanced T1-weighted turbo spin-echo sequences, T2weighted turbo spin-echo sequences, T1-weighted fat saturated images (T1-FATSAT). Diffusion weighted imaging (DWI) and gradient imaging (GRE) acquired with GE 16 channel 1.5 Tesla MRI. The findings were further compared with surgical and histopathological results. Results: Among the twenty nine patients who were examined with CT or MRI six patients were found normal. The rest of the twenty three patients who had positive findings on imaging include seventeen squamous cell carcinoma (SCC), one thyroglossal duct cyst, two venous malformations, one hemangioma, one case of lipoma and macroglossia. Conclusions: Though MR is the sensitive imaging modality for tongue evaluation, CT is most commonly used in preoperative assessment and post-operative surveillance. CT and MRI provide good anatomic detail, precise delineation of the extent of mass lesions and their relation to surrounding structures. In addition, MR imaging is helpful when flow void is identified, it can further characterize the type of flow present. Angiography is valuable for delineating feeding and draining vessels and in defining the hemodynamic of vascular lesions.

Rispetto al solo esame clinico la tomografia computerizzata (TC) e la risonanza magnetica (RM) permettono una più accurata stadiazione dei carcinomi della lingua. La complessa anatomia e la delimitazione della neoplasia rispetto ai tessuti circostanti possono rendere difficoltosa l'interpretazione degli esami TC e RM. Lo scopo di questo lavoro è di illustrare, mediante una sistematica revisione della letteratura, la tecnica d'esame i criteri semeiologici TC e RM nella valutazione e nella stadiazione del carcinoma della lingua.

Pre-operative staging of carcinoma of tongue using Ultrasonography and Magnetic Resonance imaging

Pre-operative staging of carcinoma of tongue using Ultrasonography and Magnetic Resonance imaging ABSTRACT Purpose. To assess the accuracy of staging tongue cancer using ultrasound (US) and magnetic resonance imaging (MRI) when compared to histopathology (HPE). Method. Biopsy confirmed, 28 cases of carcinoma of tongue were prospectively studied. A TNM stage was assigned to each patient using MRI and US in this double blind study. The gold standard stage on HPE was then correlated with MRI/US stage. Statistical analysis was performed. Results. Most of the patients 75% (21/28) at presentation were stage II or more. MRI staging had an overall accuracy of 82.1%( 23/28) while US had 57.1% (16/28) overall accuracy. The difference in staging was not statistically significant on Fischers exact test. US was more accurate in evaluating larger tumors. For stage 1, II and III MRI was 83.3% accurate. US achieved an accuracy of 16.6% for stage I and an accuracy of 66.6% for stage II and III. For...

Objective. Oral cancer is primarily a disease of epithelial origin. The tongue is the most common site of oral cancer. Oropharyngeal cancer accounts for approximately 2% of all cancer deaths. The purpose of this study was to analyze a case series of patients with tongue cancer. Study design. The medical records of 322 consecutive patients diagnosed with squamous cell carcinoma (SCC) of the tongue treated from 1979-1994 were reviewed. Results. Patients had a mean age of 61.1 years and a 1.5:1 male to female ratio. Approximately, half of the cancers were diagnosed at an advanced stage and most involved the base of the tongue. The majority of oral tongue tumors were diagnosed at an early stage and had more well-differentiated cell types than those of the base of the tongue. Localized discomfort was the most common complaint (66.5%), present for up to 6 months in patients prior to diagnosis and were related to the oral tongue in 90% of cases. Symptoms associated with base of tongue lesions included neck masses, dysphagia, ear pain, and weight loss. Seventy-nine percent of the patients smoked, 58% consumed alcohol on a daily basis, and 43% consumed more than 4 alcoholic drinks daily.Primary radiotherapy was the treatment of 49.6% lesions, of which 57% were at an early stage at diagnosis. The mean overall survival was 3 years and 5 months, with a 5-year overall survival of 40%. Patients with stage 1 tumors had a disease-specific survival of over 80%. The 5-year survival of patients with cancer of the oral tongue was 43% and cancer of the base of the tongue was 27%. Conclusion. The prognosis is poorer for patients presenting with advanced stage and with tumors involving the base of the tongue. Symptoms were more common in tumors of the oral tongue, which likely results in earlier diagnosis. Patients with SCC of the base of the tongue presented with advanced stage of disease and were typically poorly differentiated lesions.
Evaluation of Tongue Cancer Using High-Resolution Sonography
Journal of Ultrasound in Medicine, 2015
Comparison With Magnetic Resonance Imaging agnetic resonance imaging (MRI) is the preferred modality for evaluation of tongue cancer. 1 Abnormalities detected on MRI are well correlated pathologically. 2 Magnetic resonance imaging provides in-depth knowledge of tumor extension both inside and outside the tongue. However, it is generally expensive and sometimes unavailable. In addition, claustrophobia, incompatibility with metallic implants, and the length of the procedure are additional considerations. Although the risk of contrast agent reactions in MRI is less than that in computed tomography, they are known to occur. 3 Magnetic resonance imaging contrast agents are to be avoided in patients with renal insufficiency. 4,5
Carcinoma base of tongue: Single institution 15 year experiences
Indian Journal of Cancer, 2012
AIMS: To report the outcome with radiotherapy and concomitant chemoradiotherapy in patients with locally advanced squamous cell carcinoma base of tongue treated and followed up at single institution over a period of 15 years. MATERIALS AND METHODS: This study was carried out by auditing the medical records of 103 patients treated at our institution between 1991 and 2006. Mean age with standard deviation of patients in the Radiotherapy only (group I) and chemoradiotherapy (group II) was 55.26 ± 14.16 and 49.81 ± 12.16 years. 46 patients were treated with radiotherapy alone and 57 patients were treated with concurrent chemo radiotherapy using infusion cisplatinum 3 weekly and 5 fluorouracil twice weekly. Mean follow up was 13.35 months. All the patients characteristic and treatment characteristics were recorded. RESULTS: There were 81 men and 22 women in the study. Group I contains 15 and 31 cases of stage III and IV tumors while group II contains 19 and 38 cases of stage III and IV respectively. Group II has shown improved loco regional control rate for the T3 and T4 tumors as compared to group I. Disease free survival and overall survival in the group II is 25.51 months and 22.53 months while group I has 8.67 months and 6.74 months respectively. Grade III mucosal toxicity incidence was higher in group II as compared to group I. CONCLUSIONS: In locally advanced squamous cell carcinoma of base of tongue tumors concomitant chemoradiotherapy with infusional cisplatinum and 5 fluorouracil results in higher disease free and overall survival as compared to radiotherapy as single modality. This better tumor response with chemoradiotherapy comes at cost of higher incidence of mucosal toxicity.
