Gode M, Faggion CM. Review of patient-reported outcomes (PROs) and non-PROs in randomized controlled trials addressing head/neck cancers. Cancer Med 2024; 13:e7036. [PMID: 38646947 PMCID: PMC11033918 DOI: 10.1002/cam4.7036] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2023] [Revised: 01/06/2024] [Accepted: 02/08/2024] [Indexed: 04/25/2024] Open
Abstract
BACKGROUND To assess the frequency of patient-reported outcomes (PROs) and non-PROs in randomized controlled trials (RCTs) addressing head/neck cancers. METHODS We included RCTs about interventions to treat head/neck cancers. PubMed was searched on September 16, 2022 and included studies published during three periods (2000-2002, 2010-2012, and 2020-2022). Data on types of outcomes and instruments to measure them were extracted and organized into PROs and non-PROs, and temporal trends for reporting outcomes were determined. RESULTS There was a reduction in the frequency of non-PROs (40% to 22%) and an increase in PROs (5% to 19%) over 20 years. The frequency of reporting both non-PROs and PROs seemed to be stable over the same period (55% to 58%). A great variety of instruments to measure PROs and non-PROs was identified. CONCLUSIONS There has been a growth in the types of PROs in more recent years, and they were more frequently reported in RCTs. However, head/neck cancer trials with a combination of PROs and non-PROs were the most prevalent.

Abstract
OBJECTIVE To analyze the epidemiological profile and the specific survival of patients diagnosed with tongue squamous cell carcinoma at the National Cancer Institute (INCA). MATERIALS AND METHODS Hospital Cancer Registry System Data and Mortality Information from 2007 to 2009 were retrieved in a retrospective cohort study of patients diagnosed with tongue squamous cell carcinoma. Specific survival was estimated using the Kaplan-Meier method. The association between independent variables and the risk of death was explored in a Cox proportional hazards regression model. RESULTS A total of 346 patients were eligible, mostly male (77.5%), smokers (87.6%), with alcohol consumption (80.9%), with low education (65.6%), advanced staging at the time of diagnosis (71.1%), and presenting a high mortality rate (72.5%). In total, 44.5% of patients underwent a surgical approach alone or associated with another treatment modality, of which 85.1% of patients underwent neck dissection and 90.1% had free surgical margins. Specific survival was 40.6% in two years and 31.2% in five years. CONCLUSION The 5-year specific survival was considered worse in individuals over 60 years, and who did not undergo surgical treatment or had surgery associated with another treatment, compared to patients undergoing isolated surgery.

Abstract
Oral cancer is a common malignant life-threatening tumor. Despite some advances in traditional therapy, mortality and mobidity rates are high due to delayed diagnosis and ineffective treatment. Additionally, some patients inevitably suffer from various fatal adverse effects during the course of therapy. Therefore, it is imperative to develop novel methods to eradicate oral cancer cells with minimal adverse effects on normal cells. Nanotechnology is a promising and novel vehicle for the diagnosis and treatment of oral cancer with encouraging recent achievements. In this review, we present state-of-the-art nanotechnology-based drug delivery systems employed in the domain of oral cancer, especially for its enhanced diagnosis and therapy. We describe in detail the types of nanotechnology used in the management of oral cancer and summarize administration routes of nanodrugs. Finally, the potential and prospects of nanotechnology-based drug delivery systems as promising modalities of diagnosis and therapy of oral cancer are highlighted.

Abstract
Oral squamous cell carcinoma (OSCC) is one of the most common malignancies worldwide, due to poor diagnosis and treatment. There is increasing evidence that demonstrates the involvement of long non-coding RNAs (lncRNAs) in carcinogenesis and cancer progression. Therefore, the aim of the present study was to explore potential lncRNA-associated features of patients with OSCC as a valuable and independent prognostic biomarker. A total of 268 lncRNA expression profiles and clinical patient information on OSCC were downloaded from The Cancer Genome Atlas database. The clinical information was exploited for prescreening, using Cox regression analysis, and differentially expressed lncRNAs (DElncRNAs) were identified using edgeR software. Using the 'caret' package, the datasets were categorized into test datasets and training datasets, respectively. Through bioinformatics, seven prognostic DElncRNAs were selected. Using the regression coefficients, a risk score based on the seven-DElncRNA signature was developed to assess the prognostic function of key DElncRNAs. According to the median risk score, patients were classified into high-risk and low-risk groups in the training and test datasets. Additionally, receiver operating characteristic (ROC) curve analysis was conducted to evaluate the sensitivity and specificity of the prognostic DElncRNAs, and the optimal cut-off point was obtained from ROC analysis. Based on the optimal cut-off point, the patients were also categorized into high-risk and low-risk groups. Notably, the optimal cut-off point was more sensitive than the median risk score, particularly in the test dataset. The Kaplan-Meier survival and log rank test analysis results indicated that the P-value, based on the optimal cut-off, was less than the median risk cut-off. Additionally, stratified analysis results revealed that the seven-DElncRNAs signature was also independent of OSCC age. Furthermore, the findings of the present study suggested that the seven-DElncRNA signature can be used as a potential prognostic indicator and may have important clinical significance in OSCC.

Diagnostic ability of contrast-enhanced computed tomography for metastatic cervical nodes in head and neck squamous cell carcinomas: significance of additional coronal reconstruction images. Pol J Radiol 2020; 85:e1-e7. [PMID: 32180847 PMCID: PMC7064011 DOI: 10.5114/pjr.2020.92668] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2019] [Accepted: 11/26/2019] [Indexed: 12/25/2022] Open
Abstract
Purpose To evaluate the significance of additional coronal reconstruction images in the diagnostic ability of contrast-enhanced computed tomography (CECT) for metastatic cervical nodes in patients with head and neck squamous cell carcinomas (HNSCC). Material and methods We retrospectively assessed 97 metastatic and 141 reactive histologically proven cervical nodes of 38 patients with HNSCC, who underwent CECT before neck dissection. Observer #1, an expert radiologist in head and neck imaging, and observer #2, a general radiologist, reviewed all CECT images. The observers first assessed the presence of nodal metastasis using axial CECT alone (A-CECT). Three days later, they reassessed its presence using combined axial and coronal CECT (A&C-CECT). Results The sensitivity of A-CECT vs. A&C-CECT was 73.2% vs. 75.3% for observer #1 (p = 0.73) and 69.1% vs. 69.1% for observer #2 (p = 1.00), respectively. The specificity of A-CECT versus A&C-CECT was 92.2% vs. 97.2% for observer #1 (p < 0.05) and 92.9% vs. 95.7% for observer #2 (p = 0.22), respectively. The accuracy of A-CECT versus A&C-CECT was 84.5% vs. 88.2% for observer #1 (p < 0.05) and 83.2% vs. 85.3% for observer #2 (p = 0.30), respectively. The area under the curve (AUC) of A-CECT vs. A&C-CECT was 0.86 vs. 0.91 for observer #1 (p < 0.05) and 0.85 vs. 0.85 for observer #2 (p = 0.80), respectively. Conclusions The specificity, accuracy, and AUC increased with the use of coronal images during the assessment by the expert radiologist. The appropriate use of coronal images allowed proper configuration recognition and improved diagnostic ability.

Abstract
OBJECTIVE The expression of microRNA-125b in tongue squamous cell carcinoma (TSCC) was detected and analyzed for its relationship with the clinicopathological features of TSCC. METHODS Real time fluorescence-quantitative polymerase chain reaction (RT-qPCR) was used to detect the expression of microRNA-125b in 35 TSCC tissues and adjacent normal tissues from 35 TSCC cases. The relationship between the expression of microRNA-125b in TSCC tissues and the clinicopathological features of patients with TSCC was analyzed. In situ hybridization (ISH) was used to detect the expression level of microRNA-125b gene in the TSCC tissues and adjacent normal tissues. RESULTS RT-qPCR results showed that the relative expression levels of microRNA-125b in the TSCC issues was 2.32±0.69, and that of normal tissues was 0.87±0.32. The statistical results showed that the expression level of microRNA-125b was significantly higher in the TSCC tissues than in the normal tissues (P<0.001). The expression level of microRNA-125b in the TSCC tissues was not significantly correlated with age, gender, pathological grade, and lymph node metastasis but was positively correlated with TNM stage. Patients with high TNM stage had high microRNA-125b expression levels (P<0.05). The ISH results showed that the expression levels of microRNA-125b in the TSCC tissues were 0.010±0.003, and that of normal tissues was 0.004±0.001. The expression levels of microRNA-125b in the 35 TSCC tissues were significantly higher than those in the normal tissues (P<0.05). CONCLUSIONS MicroRNA-125b is highly expressed in TSCC and associated with TNM stage, suggesting that high microRNA-125b expression may be involved in the development of TSCC.

Front Pharmacol 2019; 10:940.

Abstract
To provide better therapeutic avenues for treating tongue squamous cell carcinoma (TSCC), a series of experiments about the effects of microRNA (miR)-532-3p on TSCC malignant behaviors were carried out. The result showed that miR-532-3p was down-regulated and C-C chemokine receptor 7 (CCR7) was up-regulated in the tumor tissues compared with those in the paired paratumor tissues. Further, expression of miR-532-3p was detected in four TSCC cell lines, TSCCA, TCA8113, CAL-27, and SCC-25. The miR-532-3p mimics and inhibitor were transfected into the CAL-27 and TCA8113 cell lines which were the relatively lowest and highest miR-532-3p expressions, respectively. It was found that the overexpression of miR-532-3p suppressed TSCC cell proliferation, migration, invasion, and promoted apoptosis in vitro, whilst the knockdown of miR-532-3p reversed these behaviors. The bioinformatics predicted that CCR7 was a downstream gene of miR-532-3p, which was confirmed via luciferase assay. Following, the decline of CCR7 in the miR-532-3p mimics group and the rise of CCR7 in the miR-532-3p inhibitor group were also verified. In addition, enhanced cell proliferation, migration and invasion induced by CCR7 were partly restrained by miR-532-3p in TSCC cell. Meanwhile, miR-532-3p attenuated tumourigenesis in vivo due to the reduction of tumor volume and Ki-67 positive rate and the increase of apoptotic cells. Taken together, these findings reveal a pivotal role for the miR-532-3p/CCR7 axis in regulating TSCC, and this novel axis could be suitable for therapeutic intervention in TSCC disease.

Abstract
OBJECTIVES The study aimed to investigate the ceRNA network in biological development of Tongue Squamous Cell Carcinoma (TSCC) and to identify novel molecular subtypes of TSCC to screen potential biomarkers for target therapy and prognosis by using integrated genomic analysis based on The Cancer Genome Atlas (TCGA) database. MATERIAL AND METHODS Data on gene expressions were downloaded from TCGA and GEO database. Differentially expressed RNAs(DERNAs) were shown by DESeq2 package in R. Functional enrichment analysis of DEmRNAs was performed using clusterprofilers in R. PPI network was established by referring to String website. Survival analysis of DERNAs was carried out by survival package in R. Interactions among mRNAs, miRNAs and lncRNAs were obtained from Starbase v3.0 and used to construct ceRNA network. Consensus Cluster Plus package was applied to identify molecular subtypes. All key genes were validated by comparing them with GEO microarray data. Statistical analyses of clinical features among different subtypes were performed using SPSS 22.0. RESULTS A total of 2907 mRNAs (1366 up-regulated and 1541 down-regulated), 191miRNAs (98 up-regulated and 93 down-regulated) and 1831 lncRNAs (1151 up-regulated and 680 down-regulated) were identified from tumor and normal tissues. A ceRNA network was successfully constructed and 15 DEmRNAs, 1 DEmiRNA, 2 DElncRNAs associated with prognosis were employed. Furthermore, we firstly identified 2 molecular subtypes, basal and differentiated, and found that differentiated subtype consumed less alcohol and was related to a better overall survival. CONCLUSION The study constructed a ceRNA network and identified molecular subtypes of TSCC, and our findings provided a novel insight into this intractable cancer and potential therapeutic targets and prognostic indicators.

Abstract
Human tongue cancer (TC) is an aggressive malignancy with a very poor prognosis. There is an urgent need to elucidate the underlying molecular mechanisms involved in TC progression. mRNA expression profiles play a vital role in the exploration of cancer-related genes. Therefore, the purpose of our study was to identify the progression associated candidate genes of TC by bioinformatics analysis. Five microarray datasets of TC samples were downloaded from the Gene Expression Omnibus (GEO) database and the data of 133 TC patients were screened from The Cancer Genome Atlas (TCGA) head and neck squamous cell carcinoma (HNSC) database. The integrated analysis of five microarray datasets and the RNA sequencing data of TC samples in TCGA-HNSC was performed to obtain 1023 overlapping differentially expressed genes (DEGs) in TC and adjacent normal tissue (ANT) samples. Next, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis was conducted to enrich the significant pathways of the 1023 DEGs and PI3KAkt signaling pathway (P=0.011) was selected to be the candidate pathway. A total of 23 DEGs with |log2 fold change (FC)| ≥1.0 in phosphatidylinositol 3-kinase-serine/threonine kinase (PI3K-Akt) signaling pathway were subjected to survival analysis of 125 eligible TC samples in TCGA database, indicating increased integrin-α3 gene (ITGA3) expression was significantly associated with poorer prognosis. Taken together, our study suggested ITGA3 may facilitate the development of TC via activating PI3K-Akt signaling pathway.

Abstract
The aim of the present study was to provide insight into various demographic, clinical, and management profile of Indian patients with oral tongue squamous cell cancer (OTSCC). All the OTSCC patients who had undergone surgical treatment during 1995 to 2010 at a tertiary care center in North India were considered for the present study. The details of the patients were retrieved from a prospectively maintained computerized database. A total of 124 patients were included in the present study. Mean age of the patients was 50.4 ± 12.0 years. Lateral border of the tongue was the most common sub-site involved in 110 (88.7%) patients. Neck nodes were clinically palpable in 56.4% patients. Hemiglossectomy and anterior partial glossectomy were common surgical procedure undertaken in 57.2 and 25.8% patients. Negative resection margin was achieved in 97.5% patients. Pathological neck metastasis was seen in 40.3% patients. Occult neck metastasis was present in 25.9% patients among clinical N0 neck. At a mean follow-up of 29.8 months (SD 3.1), 20.1% developed disease relapse and 4.0% patients developed second primaries. Kaplan-Meier analysis estimated a 5-year disease-free survival of 81.5% and a 5 years overall survival of 78.6%. Cox proportional regression analysis predicted tumor size and number of positive nodes to be independent predictive variables for disease recurrence. Quality controlled surgery, coupled with adjuvant treatment when required, provides a safe and effective treatment of OTSCC with a good disease-free survival and loco-regional control.

Abstract
Recent studies have demonstrated that mesenchymal stem cells (MSC) exhibit a tropism to tumors and form the tumor stroma. In addition, we found that MSC can secrete different types of factors. However, the involvement of MSC‐derived factors in human tongue squamous cell carcinoma (TSCC) growth has not been clearly addressed. The CCN family includes multifunctional signaling molecules that affect the initiation and development events of various tumors. In our study, we report that CCN2/connective tissue growth factor (CTGF) was the most highly induced among the CCN family members in MSC that were co‐cultured with TSCC cells. To evaluate the relationship between CCN2 and TSCC growth, we downregulated MSC‐derived CCN2 expression with shRNA targeting CCN2 and found that MSC‐secreted CCN2 promotes TSCC cell proliferation, migration and invasion. We also confirmed that MSC‐derived CCN2 partially accelerated tumor growth in vitro. Taken together, these results suggest that MSC‐derived CCN2 contributes to the promotion of proliferation, migration and invasion of TSCC cells and may be a possible therapy target in the future.

Abstract
BACKGROUND AKT1, also known as PKBα, is abnormally expressed in various malignancies. In this study, we aimed to evaluate the role of AKT1 in the tongue squamous cell carcinoma (TSCC) and further clarify the mechanisms of AKT1 in the migration and invasion of TSCC. METHODS At first, immunohistochemistry (IHC) was conducted to detect the expression of AKT1 in TSCC. Then, we determined the role of AKT1 in the migration and invasion of TSCC and further investigated whether AKT1 was the target gene of miR-138 using dual luciferase reporter assays and Western blot. RESULTS Immunohistochemistry results suggested that AKT1 dysregulation was a frequent event in TSCC, and upregulation of AKT1 was correlated with lymph node metastasis and associated with reduced overall survival. UM1 cells with higher migratory and invasive abilities had more robust AKT1 protein expression than UM2 cells with lower migratory and invasive abilities. The migration and invasion abilities were inhibited in UM1 cells upon AKT1 knockdown, meanwhile resulted in a decline of metastasis-related proteins (vimentin, slug, and pERK1/2), and upregulation of E-cadherin. Luciferase assays revealed that AKT1 was directly targeted by miR-138, and ectopic transfection of miR-138 reduced the expression of AKT1 protein. CONCLUSIONS Our results confirm that upregulation of AKT1, a miR-138 target gene, is a frequent event in TSCC and contributes to the aggressive behaviors and poor prognosis of TSCC.

Abstract
BACKGROUND AND PURPOSE The increasing impact of diagnosing extracapsular spread by using imaging, especially in patients with oropharyngeal squamous cell carcinoma, highlights the need to rigorously evaluate the diagnostic accuracy of imaging. Previous analysis suggested 62.5%-80.9% sensitivity and 60%-72.7% specificity. Our goals were to evaluate the accuracy of imaging in diagnosing extracapsular spread in a cohort of patients with oral cavity squamous cell carcinoma (pathologic confirmation of extracapsular spread routinely available), as a proxy for oropharyngeal squamous cell carcinoma, and to independently assess the reliability of imaging features (radiographic lymph node necrosis, irregular borders/stranding, gross invasion, and/or node size) in predicting pathologically proven extracapsular spread. MATERIALS AND METHODS One hundred eleven consecutive patients with untreated oral cavity squamous cell carcinoma and available preoperative imaging and subsequent lymph node dissection were studied. Two neuroradiologists blinded to pathologically proven extracapsular spread status and previous radiology reports independently reviewed all images to evaluate the largest suspicious lymph node along the expected drainage pathway. Radiologic results were correlated with pathologic results from the neck dissections. RESULTS Of 111 patients, 29 had radiographically determined extracapsular spread. Pathologic examination revealed that 28 of 111 (25%) had pathologically proven extracapsular spread. Imaging sensitivity and specificity for extracapsular spread were 68% and 88%, respectively. Radiographs were positive for lymph node necrosis in 84% of the patients in the pathology-proven extracapsular spread group and negative in only 7% of those in the pathologically proven extracapsular spread-negative group. On logistic regression analysis, necrosis (P = .001), irregular borders (P = .055), and gross invasion (P = .068) were independently correlated with pathologically proven extracapsular spread. CONCLUSIONS Although the specificity of cross-sectional imaging for extracapsular spread was high, the sensitivity was low. Combined logistic regression analysis found that the presence of necrosis was the best radiologic predictor of pathologically proven extracapsular spread, and irregular borders and gross invasion were nearly independently significant.

Abstract
The incidence of tongue carcinoma in Trinidad and Tobago and the greater West Indies is unknown; therefore, the present study examines the frequency of tongue carcinoma cases, drawing comparisons to worldwide and regional data. A retrospective analysis of all confirmed cases of tongue carcinoma was conducted using eight years of data from the pathology records at the Port of Spain General Hospital (Port of Spain, Trinidad and Tobago). A total of 26 cases were confirmed, of which 21 were male (81%) and five were female (19%). The age range was 29-86 years, with a mean age of 57 years, and the most common group affected was the 61-70 years age group. In addition, the number of newly diagnosed cases per year ranged between one and seven, with an average of 3.25 new cases per year and a peak incidence of seven new cases in the year of 2009. In the 19 cases where the degree of differentiation was recorded, histological analysis revealed the extent of differentiation as follows: Five cases (26%) were poorly-differentiated squamous cell carcinoma (SCC); eight cases (42%) were moderately-differentiated SCC; and six cases (32%) were well-differentiated SCC. In addition, one case of chronic inflammatory process and one case of mucoepidermoid adenocarcinoma of the tongue in a 57-year-old female were identified. Overall, the incidence of tongue carcinoma in Trinidad and Tobago appears to be low, estimated at 0.46/100,000 individuals/year. The male:female ratio is 4:1 and SCC is the dominant cancer type (96% of cases). The peak age of occurrence is at 61-70 years. These findings are in agreement with previously determined global data, however, additional research of the risk factors and outcomes of surgery as a treatment strategy for tongue carcinoma is required.

Abstract
This study investigated the metastatic potential of tongue squamous cell carcinoma (TSCC) cells after X-ray irradiation as well as radiation-induced changes in the biomechanical properties and cytoskeletal structure that are relevant to metastasis. Tca-8113 TSCC cells were X-ray-irradiated at increasing doses (0, 1, 2, or 4 Gy), and 24 h later, migration was evaluated with the wound healing and transwell migration assays, while invasion was assessed with the Matrigel invasion assay. Confocal and atomic force microscopy were used to examine changes in the structure of the actin cytoskeleton and Young's modulus (cell stiffness), respectively. X-ray radiation induced dose-dependent increases in invasive and migratory potentials of cells relative to unirradiated control cells (p < 0.05). The Young's modulus of irradiated cells was decreased by radiation exposure (p < 0.05), which was accompanied by alterations in the integrity and organization of the cytoskeletal network, as evidenced by a decrease in the signal intensity of actin fibers (p < 0.05). X-ray irradiation enhanced migration and invasiveness in Tca-8113 TSCC cells by altering their biomechanical properties and the organization of the actin cytoskeleton. A biomechanics-based analysis can provide an additional platform for assessing tumor response to radiation and optimization of cancer therapies.

SOD2 is a C-myc target gene that promotes the migration and invasion of tongue squamous cell carcinoma involving cancer stem-like cells. Int J Biochem Cell Biol 2015; 60:139-46.

Abstract
Our previous studies revealed that manganese superoxide dismutase (SOD2) contributes to the migration and invasion of tongue squamous cell carcinoma (TSCC). The purpose of the current study was to further clarify the mechanisms of SOD2 in the migration and invasion of TSCC. Side population (SP) cells were used as cancer stem-like cells and further assessed by sphere and colony formation assays, and the expression of stem cell markers (Bmi1, Nanog and ABCG2). We found that UM1 cells (TSCC cells with increased SOD2 expression, migration and invasion abilities) possessed a higher proportion of SP cells, sphere and colony formation, and expressed a higher level of stem cell markers compared to UM2 cells (reduced SOD2 expression, migration and invasion abilities). SOD2 expression as well as migration and invasion abilities were enhanced in SP cells compared to non-SP cells. Knockdown of SOD2 in UM1 cells or SP cells inhibited the migration and invasion abilities, reduced sphere and colony formation, and the expression of stem cell markers. Direct binding of the C-myc protein to the SOD2 promoter was demonstrated by chromatin immunoprecipitation and luciferase assays. Knockdown of C-myc in UM1 cells inhibited SOD2 expression as well as migration and invasion abilities. Our results indicate that cancer stem-like cells play an important role in the migration and invasion of TSCC. SOD2 is a direct target gene of C-myc and C-myc-SOD2-mediated migration and invasion of TSCC involve cancer stem-like cells.

Abstract
Background Humans and dogs are affected by squamous cell carcinomas of the oral cavity (OSCC) in a considerably high frequency. The high mobility group A2 (HMGA2) protein was found to be highly expressed in human OSCC and its expression was suggested to act as a useful predictive and prognostic tool in clinical management of oral carcinomas. Herein the expression of HMGA2 and its sister gene HMGA1 were analysed within human and canine OSCC samples. Additionally, the HMGA negatively regulating miRNAs of the let-7 family as well as the let-7 regulating gene Lin28 were also comparatively analysed. Deregulations of either one of these members could affect the progression of human and canine OSCC. Methods Expression levels of HMGA1, HMGA2, Lin28, let-7a and mir-98 were analysed via relative qPCR in primary human and canine OSCC, thereof derived cell lines and non-neoplastic samples. Additionally, comparative HMGA2 protein expression was analysed by immunohistochemistry. Results In both species, a significant up-regulation of the HMGA2 gene was found within the neoplastic samples while HMGA1 expression did not show significant deregulations. Comparative analyses showed down-regulation of mir-98 in human samples and up-regulation of let-7a and mir-98 in canine neoplastic samples. HMGA2 immunostainings showed higher intensities within the invasive front of the tumours than in the centre of the tumour in both species. Conclusions HMGA2 could potentially serve as tumour marker in both species while HMGA1 might play a minor role in OSCC progression. Comparative studies indicate an inverse correlation of HMGA2 and mir-98 expression in human samples whereas in dogs no such characteristic could be found.

Abstract
BACKGROUND The purpose of this study was to investigate the prognostic impact of comorbidity and of demographic and pathological factors on oral tongue squamous cell carcinoma (SCC) survival, and to compare the prognostic performance of a new clinicopathological model against the routinely used TNM staging. METHODS We conducted a retrospective study of demographic, clinical, and pathological information of 166 patients with oral tongue SCC. Cox regression was used for multivariate analysis, model building, and model discriminatory analysis. RESULTS Comorbidity had the most significant impact on overall survival (OS; log-rank test, chi-square = 36.34; p < .0001). Comorbidity, tumor dimension >2 cm, and presence of extracapsular spread (ECS) or vascular invasion were independent predictors of survival. A clinicopathological model based on these 4 variables (chi-square = 60.23; p < .0001) was better (c-statistic = 0.736) at predicting survival compared to pathological TNM staging (c-statistic = 0.645). CONCLUSION Comorbidity combined with tumor dimension, ECS, and vascular invasion provide a better prediction of oral tongue SCC survival than TNM staging alone.

Abstract
CONCLUSIONS The findings of this study demonstrated that the wait-and-watch strategy for neck metastasis from squamous cell carcinoma (SCC) of oral tongue is a reliable option and that salvage by surgical treatment is effective. However, younger patients should be closely monitored for recurrence. Adjuvant therapy may be recommended for patients with pathologically advanced disease. OBJECTIVES Metastatic involvement of cervical lymph nodes is the most important prognostic indicator in patients with oral tongue SCC. With the objective of determining the most appropriate treatment strategy for regional recurrence, we conducted a retrospective review of clinicopathologic factors. METHODS The clinicopathologic features of 103 patients with oral tongue SCC, in whom the local lesions were treated successfully by low-dose interstitial brachytherapy (LD-IBT), but who subsequently developed cervical lymph node metastases and were treated by salvage surgery, were reviewed. RESULTS In the patients who underwent surgical treatment at our hospital, 5-year disease-free survival and regional control rates were 69.3% and 85.3%, respectively. The clinicopathologic factors significantly associated with unfavorable disease-free survival were the presence of extracapsular spread (hazard ratio (HR) = 3.005, p = 0.045), multiple and large lymph nodes (HR = 2.850, p = 0.010 and HR = 3.112, p = 0.007, respectively), younger age (HR = 2.429, p = 0.048), and shorter interval from the LD-IBT to detection of neck metastasis (HR = 1.749, p = 0.013).

Abstract
Our previous studies had revealed that the dysregulation of manganese superoxide dismutase (SOD2) expression was a frequent event in tongue squamous cell carcinoma (TSCC) and may be associated with enhanced metastatic potential. To further evaluate the mechanism of SOD2-mediated metastasis in TSCC, TSCC cell lines with different metastatic potentials (i.e., the highly metastatic UM1 line and the UM2 line, which displays fewer metastases) were used. Compared to UM2 cells, UM1 cells exhibited significantly higher SOD2 activity and intracellular H(2)O(2); higher protein levels of Snail, MMP1, and pERK1/2; lower protein levels of E-cadherin; and no difference in catalase activity. Upon knockdown of SOD2 by RNA interference, UM1 cells displayed significantly reduced migration and invasion abilities; reduced activities of SOD2; lower intracellular H(2)O(2); decreased protein levels of Snail, MMP1, and pERK1/2; and increased protein levels of E-cadherin. The migration and invasion abilities of UM2 and SOD2 shRNA-transfected UM1 cells were enhanced by H(2)O(2) treatment and accompanied by increased protein levels of Snail, MMP1, and pERK1/2 and decreased protein levels of E-cadherin. Moreover the migration and invasion abilities of UM1 cells were decreased after catalase treatment. Thus, we conclude that the SOD2-dependent production of H(2)O(2) contributes to both the migration and the invasion of TSCC via the Snail signaling pathway, through increased Snail, MMP1, and pERK1/2 protein levels and the repression of the E-cadherin protein.

Abstract
PURPOSE Except for early stages (T1/2 N0), the prognosis for patients with oral cavity cancer (OCC) is known to be worse than for those with pharyngeal carcinoma. While definitive intensity modulated radiation therapy (IMRT)-chemotherapy affords loco-regional control rates (LRC) of approximately 80% in advanced pharyngeal cancer, corresponding rates are reported to be much lower for OCC. The aim of this work was to evaluate loco-regional disease control and overall survival (OAS) in a relatively large OCC patient cohort treated in the IMRT era. METHODS AND MATERIALS Between October 2002 and June 2011, 160 OCC patients were treated with curative intention IMRT at our department. 122 patients (76%) were referred with primary disease and 38 patients (24%) with a recurrent OCC at least 3 months after surgery alone. Definitive IMRT was performed in 44/160 patients (28%), whilst 116 patients underwent previous surgery. Simultaneous systemic therapy was administered in 72%. RESULTS Patients with postoperative IMRT (+/-systemic therapy) with R0-1 status (n = 99) reached significantly higher LRC/OAS rates than patients following IMRT for macroscopic disease (n = 61), with 84%/80% versus 38%/33% at 3 years, respectively (p < 0.0001). This was found in patients treated for initial, as well as recurrent, disease. Less than 2% persisting grade 3/4 late effects were observed. CONCLUSIONS IMRT for R0-1 situations translated into a highly significant superior LRC and OAS compared to the IMRT cohort treated for macroscopic disease. Treatment was well tolerated.
