Squamous cell carcinoma initially occurring on the tongue dorsum: a case series report with molecular analysis. Diagn Pathol 2024; 19:63. [PMID: 38650013 PMCID: PMC11034101 DOI: 10.1186/s13000-024-01487-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Accepted: 04/13/2024] [Indexed: 04/25/2024] Open
Abstract
BACKGROUND Squamous cell carcinoma (SCC) of the dorsum of the tongue is extremely rare, and it clinically resembles various benign lesions. Somatic mutations in TP53 and some driver genes were implicated in the development of SCC; however, the somatic genetic characteristics of dorsal tongue SCC remain unknown. With a detailed analysis of gene mutations in dorsal tongue SCC, we aimed to better understand its biology. METHODS Four cases of SCC initially occurring on the tongue dorsum were evaluated for clinical and histological findings and immunohistochemical expression of p53 and p16. Gene mutations were analyzed using next-generation sequencing with a custom panel of driver genes. RESULTS We retrospectively investigated 557 cases of tongue SCC, and only four cases of SCC initially occurred on the tongue dorsum. The four patients (cases 1-4) were one woman and three men with a mean age of 53.75 years (range: 15-74 years). Histological analysis revealed well-differentiated SCC. Through molecular analysis, we identified pathogenic somatic mutations, namely, TP53 p.C176F (c.527G > T) in case 3 and TP53 p.R282W (c.844 C > T) in case 4. No pathogenic variants were identified in the PI3K/AKT or RAS/RAF pathways. The p53 immunohistochemical examination revealed a wild-type expression pattern in cases 1-3 and strong expression in case 4. The results of p16 immunostaining were negative in all cases. CONCLUSIONS We described four previously unreported genetic characteristics of dorsal tongue SCC. Somatic TP53 mutations may contribute to the development of a subset of dorsal tongue SCC; however, more cases with genetic analysis need to be accumulated.

An anatomical perspective on clinicopathological characteristics and treatment outcomes of dorsal and ventrolateral tongue leukoplakia after carbon dioxide laser surgery. BMC Oral Health 2021; 21:45. [PMID: 33509189 PMCID: PMC7844937 DOI: 10.1186/s12903-021-01403-8] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2020] [Accepted: 01/08/2021] [Indexed: 12/18/2022] Open
Abstract
Background The tongue has been identified as a high-risk site for malignant transformation of oral leukoplakia. The purpose of this study was to investigate the clinicopathological characteristics and treatment outcomes of the dorsal and ventrolateral tongue leukoplakia. Methods Demographic data and pathological results of patients who underwent carbon dioxide laser surgery for tongue leukoplakia from 2002 to 2019 were retrospectively reviewed and analyzed statistically. Results Of the 111 patients enrolled, 80 were males and 31 females, with a mean age of 51.86 ± 11.84 years. The follow-up time was 3.74 ± 4.19 years. Fifteen patients had a postoperative recurrence (13.51%). Four (3.6%) patients developed malignant transformation. Annual transformation rate was 4.03%. There were no differences in the time to develop carcinoma (3.19 ± 1.94 vs. 3.51 ± 2.12 years, P = 0.83), overall cumulative malignant transformation rates (7.41% vs. 2.25%, P = 0.12), and annual transformation rates (2.32% vs. 0.64%, P = 0.099). The prevalence of the ventrolateral tongue leukoplakia was higher than that of the dorsal tongue leukoplakia (P < 0.001). The results of multivariate logistic regression analysis showed that the degree of pathology was the only independent prognostic factor related to postoperative malignant transformation (P = 0.045). Conclusions Dorsal tongue leukoplakia is not as frequently encountered clinically as ventrolateral tongue leukoplakia. The response of the dorsal tongue and ventrolateral tongue leukoplakia to laser therapy of are comparable in postoperative recurrence and postoperative malignant transformation. Clinicians should take a more aggressive attitude toward oral tongue leukoplakia with higher grade of dysplasia.

Ravikanth R. MR evaluation of tongue carcinoma in the assessment of depth of invasion with histopathological correlation: A single center experience. Indian J Radiol Imaging 2020; 30:126-138.

Abstract
Introduction Magnetic resonance imaging (MRI) has become the cornerstone for pretreatment evaluation of carcinoma tongue and provides accurate information regarding the extent of the lesion and depth of invasion that helps the clinician to optimize treatment strategy. Aim of the study is to correlate MRI and histopathological findings, to evaluate the role of MRI in loco-regional tumor node metastasis (TNM) staging, and to assess the depth of invasion of tongue carcinoma. Materials and Methods This study was undertaken on 30 patients with clinical diagnosis of tongue carcinoma referred for MR imaging at a tertiary care hospital over the 2-year period between July 2017 and June 2019. MRI was performed with GE 1.5 Tesla scanner, neurovascular (NV) array coil. Clinical and MRI staging of tongue carcinoma was done preoperatively and correlated. Post-surgery, histopathological TNM staging was done and correlated with clinical and MRI TNM staging. The cutoff value of histopathological (HP) depth that could determine the existence of nodal metastasis was 5 mm. Results In 30 patients diagnosed with tongue carcinoma, the incidence was higher in males (92%). Moderate agreement (k = 0.512) was noted for T staging between clinical and MRI staging assessments. Fair agreement (k = 0.218) was noted for N stage between clinical and MRI staging assessments. There was good agreement (k = 0.871) for M stage between the clinical and MRI staging assessments. Good agreement (k = 0.822 and k = 0.767, respectively) was noted for both T staging and Nstaging between MRI and histopathology staging assessments. The agreement for the T stage was poor (k = 0.012) between the clinical and histopathology staging assessments. Agreement for the N stage was also poor (k = 0.091) between the clinical and histopathology staging assessments. Mean depth of invasion by histology and MRI was 14.22 mm and 16.12 mm, respectively. Moderate agreement (k = 0.541) was noted between clinical and pathological tumor depth and good agreement (k = 0.844) was noted between radiological and pathological tumor depth. As for the T1WGd MRI depth with a cutoff value of 5 mm, the nodal metastasis rate in the group with values >5 mm was 52%, and for those <5 mm was 24%, both of which were significantly different (P = 0.040). Pearson's correlation coefficient of HP depth and T1WGd MRI depth was 0.851 (P < 0.001) suggesting that HP depth shows a strong correlation with T1WGd MRI depth. Conclusion MRI is the imaging modality of choice for evaluation of tongue carcinoma as MRI helps in accurate staging of the tumor using TNM classification which is crucial for optimizing treatment options. The current study shows a high correlation between MRI and histopathological findings regarding thickness of tumor and depth of invasion. MRI and histopathology assessments of tumor spread were equivalent to within 0.5 mm DOI. Estimation of invasion depth using MRI as a preoperative study in oral tongue carcinoma is essential in planning surgical treatment strategies such as the extent of elective neck dissection. Invasion depth, which greatly affects occult node metastases, must be included in the TNM staging of oral tongue carcinoma.

Abstract
The aim of this study is to evaluate the efficacy and long-term outcome of a modification of the anterior-posterior tongue rotation flap used for reconstruction of tongue following cancer ablation. From April 2016 to September 2017, 21 consecutive patients with tumor classification (T2), lymph node classification (N0) tongue cancer on the anterior and middle one-third portion were selected for this study. A modification of the anterior-posterior tongue rotation flap was selected for tongue reconstruction after the cancer resection. Patient's scorings of swallowing, chewing, speech and taste were recorded. Patient after tongue flap reconstruction acquired satisfied tongue movement that allows normal functional outcomes for swallowing, chewing, speech and taste. Local tumor recurrence was not observed during the follow-up examination (range, 12-24 months). The modification of the anterior-posterior tongue rotation flap was a safe and reliable treatment for medium-size tongue cancer (T2N0), especially suitable to patients who cannot endure prolonged surgery.

Abstract
Adenosquamous carcinoma (ASC) is a rare malignant tumor of the oral and maxillofacial region that displays histologic features of both adenocarcinoma and squamous cell carcinoma. ASC in the midline dorsum of the tongue is exceedingly rare. We report the case of a 48-year-old man who presented with a painless mass in the midline dorsum of the tongue. Although the case was diagnosed as adenocarcinoma by biopsy, a final diagnosis of ASC was established after surgery. Ten months after the patient's initial visit, no recurrence or metastasis has been noted. ASC in the middle dorsum of the tongue is exceedingly rare, and no examples have been reported hitherto.

Abstract
The tongue's deformation during speech can be measured using tagged magnetic resonance imaging, but there is no current method to directly measure the pattern of muscles that activate to produce a given motion. In this paper, the activation pattern of the tongue's muscles is estimated by solving an inverse problem using a random forest. Examples describing different activation patterns and the resulting deformations are generated using a finite-element model of the tongue. These examples form training data for a random forest comprising 30 decision trees to estimate contractions in 262 contractile elements. The method was evaluated on data from tagged magnetic resonance data from actual speech and on simulated data mimicking flaps that might have resulted from glossectomy surgery. The estimation accuracy was modest (5.6% error), but it surpassed a semi-manual approach (8.1% error). The results suggest that a machine learning approach to contraction pattern estimation in the tongue is feasible, even in the presence of flaps.

Abstract
Squamous cell carcinoma (SCC) of the tongue is the most common oral cancer. Most cases occur on the lateral border of the tongue and only very rarely on the dorsum. We retrospectively investigated the incidence of SCC of the tongue dorsum in our department between April 2006 and March 2015. Of the 368 patients with tongue cancer, only 3 had SCC of the tongue dorsum (incidence, 0.8 %). All patients with advanced cancer of the tongue dorsum underwent superselective intra-arterial chemoradiotherapy for organ preservation. We discuss the present findings in relation to past case reports and series in the English language literature as well as discuss treatments for SCC of the tongue dorsum.

Abstract
PURPOSE The object of this study was to evaluate the usefulness of preoperative transbuccal ultrasound (US) for the evaluation of tongue tumors. Thus, we evaluated the correlation between preoperative US measurements and postoperative pathologic measurements of tongue tumor size. METHODS From January 2003 to March 2011, 29 patients with tongue tumors were evaluated. All patients underwent preoperative transbuccal US at 1 day before surgery. Preoperative US was compared with pathology findings, including specimen size. The maximum anterior-posterior (AP) diameter of the long axis of the tumor, the maximum width (WD), and the maximum thickness (TH) of the tumor were measured with US along with a pathologic evaluation of the specimens. RESULTS The mean AP was 22 ± 1 mm; WD was 13 ± 6 mm, and TH was 10 ± 5 mm using US. The pathologic mean AP was 21 ± 12 mm; WD was 12 ± 6 mm, and TH was 9 ± 4 mm. The Spearman's correlation coefficients of the AP, WD, and TH were 0.905 (p < 0.001), 0.918 (p < 0.001), and 0.971 (p < 0.001), respectively. CONCLUSIONS Transbuccal US is a useful tool for predicting tongue tumor extent.

Abstract
A hypothesis that OSCCs originating from different types of oral epithelia may have different patient and tumor characteristics was evaluated in this retrospective analysis of 188 patients with primary OSCC treated at Turku University Central Hospital, Turku, Finland in 1988-1997. The tumors were categorized according to the type of oral epithelium from which they have originated: (1) specialized epithelium (dorsal tongue) (2) keratinized (masticatory) epithelium, (3) non-keratinized (lining) epithelium, and (4) tongue epithelium (epithelium on the lateral border of the tongue). The relevant clinical data, including age, sex, social status, and risk behavior of the patients and clinical presentation, histopathological grading, and treatment of the tumors, as well as the follow-up information, were collected from the patient charts of the hospital. In general, tumor and patient characteristics of OSCCs and survival rates were found to be in line with those of recent analyses reported from other industrialized countries. However, OSCCs in young patients (4.8%) seemed to be clinically at a lower stage and histologically more highly differentiated than those of the other patients. Eight out of 9 (89%) OSCCs in the young patients were located on the lateral tongue. The 5-year recurrence-free rates of the patients according to the epithelial origin of the tumors were as follows: masticatory epithelium 42%, lining epithelium 57%, and epithelium of the lateral border of the tongue 61%. In conclusion, the tumors originating from different types of oral epithelia may have distinct properties with regard to their clinical behavior and responsiveness to the different treatment modalities. It would seem to be meaningful to investigate the molecular characteristics of the different types of oral epithelium in order to elucidate possible differences in their susceptibility to malignant transformation.
