In Vitro and In Vivo Analyses Reveal Tumor-Derived Exosome miR-558 Promotes Angiogenesis in Tongue Squamous Cell Carcinoma by Targeting Heparinase. Technol Cancer Res Treat 2024; 23:15330338241261615. [PMID: 38887096 PMCID: PMC11185026 DOI: 10.1177/15330338241261615] [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: 02/14/2024] [Revised: 05/16/2024] [Accepted: 05/21/2024] [Indexed: 06/20/2024] Open
Abstract
This study aimed to investigate the role of miR-558 in tumor angiogenesis by targeting heparinase (HPSE) in tongue squamous cell carcinoma (TSCC)-derived exosomes. In the present study, the role of exosome miR-558 in angiogenesis in vitro and in vivo was investigated by cell proliferation, migration, tube formation, subcutaneous tumor formation in mice, and in vivo Matrigel plug assay. The target genes of miR-558 were detected by means of dual luciferase assay. It was found that TSCC cells secrete miR-558 into the extracellular environment, with exosome as the carrier. Human umbilical vein endothelial cells (HUVEC) ingested exosomes, which not only increased the expression level of miR-558, but also enhanced their proliferation, migration, and tube formation functions. In vivo Matrigel plug assay demonstrated that TSCC cell-derived exosome miR-558 promoted neovascularization in vivo. Compared with negative control cells, TSCC cells overexpressing miR-558 formed subcutaneous tumors in nude mice, with larger volume, heavier mass, and more vascularization. Dual luciferase assay confirmed that HPSE was the direct target gene regulated by miR-558. HPSE promoted the proliferation, migration, and tube formation of HUVECs, and the knockout of HPSE could downregulate the pro-angiogenic effect of miR-558. In summary, miR-558 in TSCC exosomes promotes the proliferation, migration, and tube formation of HUVECs by targeting HPSE, and enhancing tumor angiogenesis.

Ooms M, Ponke L, Winnand P, Heitzer M, Peters F, Steiner T, Hölzle F, Modabber A. Predictive factors and repetition numbers for intraoperative additional resection of initially involved soft tissue resection margins in oral squamous cell carcinoma: a retrospective study. World J Surg Oncol 2023; 21:308. [PMID: 37752503 PMCID: PMC10523667 DOI: 10.1186/s12957-023-03192-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2023] [Accepted: 09/17/2023] [Indexed: 09/28/2023] Open
Abstract
BACKGROUND Intraoperative additional resection (IAR) of initially microscopically involved soft tissue resection margins negatively impacts tumor recurrence in oral squamous cell carcinoma (OSCC). Increasing the selected initial macroscopic resection margin distance beyond the tumor tissue may help prevent IAR; however, the existence of predictive factors for IAR and IAR repetition numbers remains unclear. This study aimed to identify predictive factors for IAR and to evaluate the IAR repetition numbers in soft tissue for surgically treated OSCC. METHODS A cohort of 197 patients surgically treated for OSCC between 2008 and 2019 was retrospectively reviewed (44 patients with IAR and 153 patients without IAR). Clinical parameters (tumor location, midline involvement, clinical T-status, time between staging imaging and surgery, bone resection, monopolar use, and reconstruction flap size) and histopathological parameters (pathologic T-status [pT-status], grading, vascular invasion, and lymphatic invasion) of the two groups were compared. RESULTS Patients with and without IAR differed in their histopathological parameters, such as pT-status above 2 (47.7% vs. 28.1%, p = 0.014) and lymphatic invasion (13.6% vs. 4.6%, p = 0.033); however, their clinical parameters were similar (all p > 0.05). Only pT-status above 2 was predictive for IAR in a multivariable regression analysis (odds ratio 2.062 [confidence interval 1.008-4.221], p = 0.048). The IAR repetition numbers varied from zero to two (zero = 84.4%, one = 11.4%, and two = 2.3%). CONCLUSIONS Only postoperative available pT-status was identified as a predictive factor for IAR, underscoring the importance of improving preoperative or intraoperative tumor visualization in OSCC before selecting the initial macroscopic resection margin distance to avoid IAR.

Abstract
BACKGROUND The impact of additional soft tissue resection on recurrence of oral squamous cell carcinoma (OSCC) remains controversial. The study aim was to compare recurrence between patients with secondary tumor-free resection margins after intraoperative additional resection (STF-RM) and patients with primary tumor-free resection margins without additional resection (PTF-RM). METHODS Forty-five patients with STF-RM were matched with patients with PTF-RM according to Union for International Cancer Control stage, tumor location, and treatment modality and compared for local, regional, and distant recurrence. RESULTS Patients with STF-RM showed lower local and distant control rates compared to patients with PTF-RM (66.2% vs. 82.8%; p = 0.045 and 86.3% vs. 100.0%; p = 0.021). STF-RM was the only predictor of local recurrence accounting for tumor (T) status, nodal (N) status, tumor grade, margin distance, and extracapsular extension (hazard ratio 4.21 [95% confidence interval 1.26-14.04]; p = 0.019). CONCLUSIONS STF-RM have an adverse impact on local and distant recurrence of OSCC.

Abstract
OBJECTIVE This study aims to systematically review the role of differentially expressed microRNA (miRNA) in saliva as potential biomarkers in oral cancer patients. DESIGN PubMed, Scopus and EBSCO online data bases were used as well as manual searching to extract studies from January 2008 up to October 2020. RESULTS A total of 14 studies that met the eligibility criteria were included. All selected studies were of case-control type. A total of 25 differentially expressed miRNAs were identified. Thirteen of these miRNAs (Let-7a, miR 27, miR 34, miR 92, miR 124, miR 125a, miR 136, miR139 miR 145, miR 146a, miR 200a, miR 205 and miR 375) were downregulated and other twelve (miR 9, miR 21, miR 31, miR 122, miR 134, miR 184, miR 191, miR 196a, miR 196b, miR 412, miR 512 and miR 8392) were upregulated. Four miRNAs were evaluated in more than one study (miR21, miR31, miR125 and miR 200). CONCLUSION According to these results, salivary miRNA can aid in diagnosis and prognosis of oral squamous cell carcinoma (OSCC). However, controlled clinical trials with a large sample size are required to validate the differentially expressed miRNAs of the present review.

Abstract
Circular RNAs (circRNAs) are a new class of "non-coding RNAs" that originate from non-sequential back-splicing of exons and/or introns of precursor messenger RNAs (pre-mRNAs). These molecules are generally produced at low levels in a cell-type-specific manner in mammalian tissues, but due to their circular conformation they are unaffected by the cell mRNA decay machinery. circRNAs can sponge multiple microRNAs or RNA-binding proteins and play a crucial role in the regulation of gene expression and protein translation. Many circRNAs have been shown to be aberrantly expressed in several cancer types, and to sustain specific oncogenic processes. Particularly, in virus-associated malignancies such as human papillomavirus (HPV)-associated anogenital carcinoma and oropharyngeal and oral cancers, circRNAs have been shown to be involved in tumorigenesis and cancer progression, as well as in drug resistance, and some are useful diagnostic and prognostic markers. HPV-derived circRNAs, encompassing the HPV E7 oncogene, have been shown to be expressed and to serve as transcript for synthesis of the E7 oncoprotein, thus reinforcing the virus oncogenic activity in HPV-associated cancers. In this review, we summarize research advances in the biogenesis of cell and viral circRNAs, their features and functions in the pathophysiology of HPV-associated tumors, and their importance as diagnostic, prognostic, and therapeutic targets in anogenital and oropharyngeal and oral cancers.

Abstract
OBJECTIVE The objective of this study was to determine correlations between magnetic resonance imaging (MRI) features including radiologic depth of invasion (r-DOI) and pathologic DOI (p-DOI) of squamous cell carcinoma of the buccal mucosa. STUDY DESIGN In total, 31 lesions were retrospectively evaluated. MRI findings included detectability, buccinator muscle invasion (positive: BMI+, negative: BMI-), buccal fat pad invasion (positive: BFPI+, negative: BFPI-), and r-DOI measured on T2-weighted images (T2-DOI) and contrast-enhanced T1-weighted images (CET1-DOI). These findings were compared to the p-DOI of the tumors. RESULTS The p-DOI values of undetectable lesions were smaller than those of detectable lesions (P < .001), and the cutoff value was 1 mm. BMI+ and BFPI+ lesions had significantly larger p-DOI values than the corresponding BMI- and BFPI- lesions (P < .001), with cutoff values of 5 and 6 mm, respectively. The correlation coefficient between CET1-DOI and p-DOI was 0.68 (P < .001). CET1-DOI values were larger than p-DOI (P < .001) and the average difference between them was 3.4 mm. T2-DOI was inconclusive in 50% of cases. Interobserver agreements of MRI evaluation were good to very good. CONCLUSION MRI-derived parameters were useful in estimating p-DOI and may be helpful in predicting the depth of invasion of tumors and the risk of lymph node metastasis.

Abstract
In disease diagnostics and health surveillance, the use of saliva has potential because its collection is convenient and noninvasive. Over the past two decades, the development of salivary utilization for the early detection of cancer, especially oral cavity and oropharynx cancer has gained the interest of the researcher and clinician. Until recently, the oral cavity and oropharynx cancers are still having a five-year survival rate of 62%, one of the lowest in all major human cancers. More than 90% of oral cancers are oral squamous cell carcinoma (OSCC). Despite the ease of accessing the oral cavity in clinical examination, most OSCC lesions are not diagnosed in the early stage, which is suggested to be the main cause of the low survival rate. Many studies have been performed and reported more than 100 potential saliva biomarkers for OSCC. However, there are still obstacles in figuring out the reliable OSCC salivary biomarkers and the clinical application of the early diagnosis protocol. The current review article discusses the emerging issues and is hoped to raise awareness of this topic in both researchers and clinicians. We also suggested the potential salivary biomarkers that are reliable, specific, and sensitive for the early detection of OSCC.

Abstract
OBJECTIVES We evaluated the relationships between depth of invasion (DOI) of tongue cancer, as measured with preoperative T1- and T2-weighted magnetic resonance imaging (MRI) and postoperative histopathologic (Path) specimens, with cervical lymph node metastasis (CLNM) and tumor stage. We also calculated the correlation of MRI and Path DOI measurements. STUDY DESIGN This retrospective study included 101 patients who had squamous cell carcinoma of the tongue and were treated surgically. Two observers measured DOI on all 3 modalities. RESULTS DOI thresholds for predicting CLNM with high diagnostic efficacy were 6.99 mm and 8.32 mm for MRI and 5 mm for Path. DOI values from all modalities were significantly different for tumors with and without CLNM (P < .01) and for the 4 TNM stages (P ≤ .05), with increasing values corresponding to advancement in tumor stage. Addition of DOI changed the T level of many tumors based on the new TNM (tumor-node-metastasis) classification. The correlation coefficient between DOI calculated on each MRI sequence and Path was 0.90. CONCLUSIONS MRI-derived DOI accurately reflected the subsequent metastatic status and degree of progression of tumor stages, with a strong positive correlation to Path values, and may be considered a predictor of tumor stage and CLNM.

Abstract
Background Long noncoding RNA taurine upregulated 1 (TUG1) has been reported to play an important role in human cancers. However, little is known about the role of TUG1 in drug resistance and its mechanism in tongue squamous cell carcinoma (TSCC). Methods Twenty-one cisplatin-sensitive or resistant TSCC patients were enrolled in this study. Cisplatin-resistant cells (SCC25/CDDP and CAL27/CDDP) were used for experiments in vitro. Transfection was performed using Lipofectamine 2000 transfection reagent. The levels of TUG1, microRNA-133b (miR-133b) and cysteine-X-cysteine chemokine receptor 4 (CXCR4) were measured by quantitative real-time polymerase chain reaction or western blot. The cisplatin resistance was investigated by cell viability, transwell invasion and apoptosis assays. The interactions among TUG1, miR-133b and CXCR4 were evaluated by luciferase reporter assay and RNA immunoprecipitation. Murine xenograft model was established using the stably transfected CAL27/CDDP cells. Results TUG1 expression was elevated in cisplatin-resistant TSCC tissues and cells compared with that in sensitive group and its knockdown inhibited cisplatin resistance to SCC25/CDDP and CAL27/CDDP cells. miR-133b was targeted via TUG1 and its overexpression suppressed cisplatin resistance. Moreover, CXCR4 was a target of miR-133b. CXCR4 silence repressed cisplatin resistance, which was reversed by miR-133b knockdown. The level of CXCR4 protein was decreased by inhibition of TUG1 and recuperated by miR-133b knockdown. Besides, interference of TUG1 attenuated tumor growth by regulating miR-133b and CXCR4 in vivo. Conclusion Downregulation of TUG1 impeded cisplatin resistance in TSCC-resistant cells by mediating miR-133b and CXCR4, indicating TUG1 as a promising target for TSCC chemotherapy.

Abstract
The 8th edition of American Joint Committee on Cancer's (AJCC) Cancer Staging Manual was modified by incorporating depth of invasion (DOI) in the T categorization of oral cavity cancer. This is because DOI is strongly associated with cervical lymph node metastasis, which is the most important negative prognostic factor of oral cavity cancer. This major change in the AJCC Cancer Staging Manual caused re-staging of T category in several cases. Although, the DOI on MRI and CT (radiological DOI; r-DOI) strongly correlated with pathological DOI (p-DOI), it is often 2-3 mm larger than p-DOI. Due to this variance, estimation of p-DOI based on r-DOI may not be accurate. However, when a lesion is undetectable on MRI, p-DOI was often smaller than 4 mm. On the other hand, when MRI depicts lesions with styloglossus and hyoglossus muscle invasion, p-DOI was always larger than 4 mm. These correlations between MRI findings and p-DOI are important when assessing the need for elective neck dissection, as the National Comprehensive Cancer Network (NCCN) recommends elective neck dissection in cases with DOI greater than 4 mm.

Usefulness of contrast-enhanced CT in the evaluation of depth of invasion in oral tongue squamous cell carcinoma: comparison with MRI. Oral Radiol 2020; 37:86-94. [PMID: 32086730 DOI: 10.1007/s11282-020-00429-y] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2019] [Accepted: 02/04/2020] [Indexed: 11/30/2022]
Abstract
OBJECTIVES There is currently no standardized approach for assessing the depth of invasion (DOI) of oral tongue squamous cell carcinoma via diagnostic imaging. We investigated the usefulness of contrast-enhanced computed tomography (CECT) for estimating the pathological DOI of oral tongue squamous cell carcinoma by evaluating the correlation of pathological DOI with the DOIs on CECT and magnetic resonance imaging (MRI). METHODS We retrospectively reviewed 21 of 139 patients who underwent radical surgery for primary oral tongue squamous cell carcinoma between 2009 and 2018. The 21 cases were evaluable, without dental artifacts on CECT. DOIs on CECT and MRI, and pathological DOI were measured. RESULTS The median pathological DOI was 9 mm, that on CECT was 10.9 mm, that on T2-weighted MRI was 14.2 mm, and that on contrast-enhanced T1-weighted MRI was 13.1 mm. The DOIs on CECT and on MRI were larger than the pathological DOI (p = 0.003 to < 0.001). The absolute value of the difference between pathological DOI and DOI on CECT was smaller than that between pathological DOI and DOI on MRI (p = 0.01 and 0.003). DOIs on CECT and on MRI correlated with pathological DOI (r = 0.74-0.66, all p < 0.001). Spearman's correlation coefficient between DOI on CECT and pathological DOI was greater than that between DOI on MRI and pathological DOI. CONCLUSIONS Compared to the DOI determined on an MRI scan, the DOI determined on a CECT scan correlated with and better approximated pathological DOI. Therefore, CECT can be useful for preoperative staging of patients with oral tongue squamous cell carcinoma.

Abstract
Tongue squamous cell carcinoma (TSCC) is the most frequent type of oral cancer associated with high malignancy. Circular RNAs (circRNAs) are a form of non-coding RNA with stable and conserved expression in mammalian cells. The aim of the present study was to investigate circRNAs expression profiles in TSCC, and examine the roles and potential mechanisms of circRNA-081069 (circ_081069). A high-throughput circRNA microarray analysis of tumor samples and adjacent normal tissues from four patients with TSCC was performed. Bioinformatic analysis was conducted to screen the differentially expressed circRNAs. Reverse transcription-quantitative PCR was performed to confirm the microarray results. A migration assay and proliferation assay were performed to detect the migratory and proliferative ability of TSCC cells. A luciferase assay was conducted to investigate the interaction between circ_081069 and microRNA (miRNA/miR)-665. In total, 335 circRNAs were found to be differentially expressed in tumor tissues. Among them, 59 were upregulated and 276 were downregulated (P<0.05; fold change ≥2 or ≤0.5). A total of seven circRNAs, including two upregulated and five downregulated circRNAs, were further confirmed using quantitative PCR analysis in the ten paired TSCC tissues and adjacent normal tissues. The present study showed that circRNA_081069 promoted the migratory and proliferative ability of TSCC cells in vitro. Furthermore, the potential circRNA-miRNA interactions were predicted, and the present results identified miR-665 as a miRNA target of circ_081069. The present results suggested that circRNAs may be involved in TSCC development, and understanding the interaction between circ_081069 and miR-665 may facilitate the development of novel diagnostic and therapeutic targets for TSCC.

Abstract
PURPOSE By comparing styloglossus and hyoglossus muscle invasion (SHMI) of oral tongue squamous cell cancer (OTSCC) on MR imaging to pathological depth of invasion (DOI) and prognosis, we aimed to evaluate the clinical significance of MR imaging findings of SHMI. METHOD Forty-five, early stages and clinically N0 OTSCCs were retrospectively reviewed. Data included pathological DOI, DOI on MR imagings, two-year potential cervical lymph node positive, locoregional control, disease-free survival, and overall survival. Data were statistically compared between the groups with MR evidence of SHMI (SHMI+) and without MR evidence of SHMI (SHMI-). RESULTS There were 17 SHMI + and 28 SHMI-. Elective neck dissections performed on 13 cases revealed five node positive cases, all of which were SHMI + . Pathological DOI in SHMI + was significantly larger than SHMI- (average 9.0 vs 4.6 mm, p < 0.001). All SHMI + revealed pathological DOI larger than 4 mm. The two-year potential cervical lymph node positive rate of SHMI + was significantly higher than SHMI- (p = 0.01). Locoregional control rate and disease-free survival of SHMI+ were significantly lower than in SHMI- (p = 0.02). There was no significant difference in overall survival. Interobserver agreement in evaluation of SHMI on MR imaging was good (kappa value = 0.72, p < 0.001). CONCLUSIONS Pathological DOIs of SHMI + were all larger than 4 mm, which is the cut-off point that National Comprehensive Cancer Network recommends for neck dissection, and SHMI + had a worse prognosis than SHMI-. SHMI + can be used as a criterion for elective neck dissection.

Abstract
INTRODUCTION Tobacco is one of the most important risk factors for premature death globally. More than 60 toxic chemicals in tobacco can invade the body’s various systems. Oral squamous cell carcinoma (OSCC) is a pathological type of oral cancer, accounting for over 90% of oral cancers. A vast quantity of scientific, clinical and epidemiological data shows that tobacco is associated with the development of oral squamous cell carcinoma, and its carcinogenic pathways may be complicated. METHODS We conducted a thorough electronic search by Cochrane, EMBASE and PubMed to identify relevant studies. Studies published up to the end of October 2018 were included. After assessing and selecting articles based on eligibility criteria, studies were classified and elaborated according to the pathogenesis. RESULTS Tobacco as an important risk factor can cause epigenetic alteration of oral epithelial cells, inhibit multiple systemic immune functions of the host, and its toxic metabolites can cause oxidative stress on tissues and induce OSCC. In addition, some specific viruses such as EBV and HPV are thought to play a role in the development of OSCC. CONCLUSIONS Oral cancer ranks eighth among the most common causes of cancer-related deaths worldwide, and tobacco is one the most important carcinogenic factors of OSCC. This review of the literature attempts to provide directions and ideas for future related research, and emphasizes the need for efforts to reduce tobacco consumption.

Abstract
Objective Oral cavity squamous cell carcinoma (SCC) may present with early invasion of mandibular bone. Preoperative planning of surgery is essential considering patient's postoperative quality of life. Our purpose was to evaluate the efficacy of computer tomography scan (CT) and magnetic resonance imaging (MRI) in detecting mandibular bone involvement in oral SCC. Methods A retrospective study was conducted on 98 patients with SCC of floor of mouth, lower alveolus and retromolar trigone operated on with curative intent. Preoperative CT and MRI scans were re-reviewed by a consultant radiologist and original histology slides were re-reviewed by 3 pathologists. Results Forty-five patients were included in the final study. Combined CT and MRI had a sensitivity of 100% and a specificity of 72%. Conclusion The results suggest that combined CT and MRI have diagnostic utility in detecting mandibular invasion by oral cancer, but with a significant false positive rate.

Abstract
METHODS: We retrospectively reviewed early stage oral tongue cancer patients treated with radical surgery with clinically N0, between May 2009 and February 2016. Collected data include age, sex, pathological DOI, DOI on MRI, locoregional control rate, disease-free survival rate, and overall survival rate. These data were statistically compared between the detectable lesion (DL) group and undetectable lesion (UL) group on MRI. Interobserver agreement in evaluation of detectability of the oral tongue cancer was assessed by k statistics. RESULTS: Total of 53 patients were studied, and 28 were DLs and 25 ULs. Pathological DOI in UL was significantly smaller than that of DL (average 1.7 vs 4.6 mm, p < 0.001). Cut-off value between UL group and DL group was 3.5 mm (sensitivity 96 %, specificity 75 %). 96 % of ULs had pathological DOI smaller than 4 mm, the recommended cut-off value for neck dissection. There was no significant difference in locoregional control rate (p = 0.24), disease-free survival rate (p = 0.24) or overall survival rate (p = 0.92). Interobserver agreement in evaluation of detectability on MRI was very good ( k-value = 0.89, p < 0.001). CONCLUSIONS: When oral tongue cancer is not detected on MRI, it indicates pathological DOI being smaller than 4 mm, which may imply that elective neck dissection is unnecessary.

Abstract
The long noncoding RNA (lncRNA) H19 has been described to participate in the metastasis of various tumors. Nevertheless, whether H19 promotes or impedes tongue squamous cell carcinoma (TSCC) cell migration and invasion remains controversial. Here we found that the expression of H19 was elevated in TSCC tissues compared with adjacent normal tissues. Moreover, we demonstrated that the expression of H19 was higher in metastasized tumors compared with unmetastasized tumors. Consistently, TSCC cells express higher levels of H19 than human squamous cells. Subsequently, depletion of H19 impaired the migration and invasion abilities of TSCC cells. Mechanistically, we demonstrated that H19 functions as a competing endogenous RNA (ceRNA) to sponge miRNA let-7a, leading to an increase in a let-7a target, the key regulator of tumor metastasis HMGA2, which is enriched in TSCC tissues and cell lines. Intriguingly, inhibition of let-7a significantly rescued the short hairpin H19 (shH19)-induced decrease in TSCC migration and invasion. These findings revealed that the H19/let-7a/HMGA2/EMT axis plays a critical role in the regulation of TSCC migration and invasion, which may provide a new therapeutic target for TSCC.

Abstract
Head and neck cancers (HNC) are one of the ten leading cancers worldwide, including a range of malignant tumors arising from the upper neck. Due to the complex mechanisms of HNC and lack of effective biomarkers, the 5-year survival rate of HNC has been low and the mortality rate has been high in recent decades. Long noncoding RNAs (lncRNAs), noncoding RNAs longer than 200 bps, are a focus of current cancer research, closely related to tumor biology. LncRNAs have been revealed to be aberrantly expressed in various types of HNC, and the dysregulated lncRNAs participate in HNC progression and induce malignant behavior by modulating gene expression at diverse levels. This review will focus on the functions and molecular mechanisms of dysregulated lncRNAs in HNC tumorigenesis and progression, as well as their diagnostic, therapeutic or prognostic implications in HNC.

Abstract
The occurrence of tongue squamous cell carcinoma (TSCC) is closely correlated with serum components; however, the detailed mechanism remains to be fully elucidated. Proteomic analysis contributed to the discovery of potential biomarkers and provided an insight into TSCC at a molecular level. The present study investigated the effect of serum deprivation on the Tca‑8113 TSCC cell line through protein profiling using two‑dimensional gel electrophoresis and mass spectrometry, with the aim of improving TSCC diagnosis. The results showed that the Tca‑8113 cells maintained proliferative capacity and resisted apoptosis following serum deprivation. A total of 43 proteins were upregulated and 45 were downregulated following serum deprivation for 24 h, compared with untreated controls (0 h). The upregulated caspase-7, heat shock protein 27 and Annexin A1, and the downregulated peroxiredoxin‑6 and heat shock protein 70, were selected for verification using reverse transcription‑polymerase chain reaction analysis following serum deprivation for 16 h. The results indicated that reactive oxygen species may be important in serum deprivation‑induced oxidative stress.

Abstract
OBJECTIVES/HYPOTHESIS Locoregional recurrences of oral cavity squamous cell carcinoma (SCC) may be diagnosed during follow-up of surgically treated patients. Nevertheless, few studies have investigated factors that impact salvage surgery failure and the mortality rates of these patients. The objectives were to identify predictive factors of salvage surgery failure and mortality in patients who undergo surgical treatment for recurrent oral cavity SCC and to compare the overall survival rates of these patients with those of patients who undergo only one surgical treatment. STUDY DESIGN Retrospective cohort study. METHODS Forty-six patients submitted to salvage surgery for local or locoregional recurrence. RESULTS The presence of lymph node metastasis and positive surgical margins at the salvage surgery time were the only independent factors associated with both recurrence rates (hazard ratio [HR]: 5.04 and 2.82, respectively) and mortality (HR: 3.51 and 3.24, respectively). When the overall survival rates of the 199 patients who only underwent one surgical treatment were compared to those of the 46 patients subjected to salvage surgery, a similarity was evident when patients who underwent salvage surgery did not have a new disease recurrence (70.7% vs. 54.7%, respectively; P = .158). Likewise, patients with new recurrences after salvage surgery and patients who received palliative treatment for relapsed disease had similar overall survival rates (0.6% vs. 0.0%, respectively; P = .475). CONCLUSIONS The presence of lymph node metastasis at the time of recurrence and positive surgical margins after the salvage surgery were associated with a worse overall survival rate in patients with oral cavity SCC relapse.

Abstract
PURPOSE Recent reports indicate that histamine and its novel, high-affinity histamine H4 receptor (H4R) play a role in carcinogenesis, and thus H4R signalling has become a focus of increasing interest in the pathogenesis of many cancers. The roles of H4R in oral epithelial dysplasia (OED) and oral tongue squamous cell carcinoma (OTSCC) are unknown. The purpose of this study was to assess H4R expression in OTSCC patients and in OTSCC-derived cell lines. METHODS Biopsies taken from OED, OTSCC and healthy oral mucosa were studied by immunostaining. Primary human oral keratinocytes (HOKs) and two OTSCC-derived cell lines (HSC-3 and SCC-25) were used for the in vitro studies. Quantitative real-time PCR was used to measure oncogene expression in the stimulated HOKs. RESULTS We found that H4R-immunoreactivity was significantly reduced in the OED and OTSCC samples, especially in the samples with higher histopathological grades and noticeably increased mast cell counts. The presence of H4R in HSC-3 cells had clearly waned, in contrast to the HOKs. Gene expression data indicated that histamine-relevant inflammatory and environmental elements may participate in the regulation of oncogenes. CONCLUSIONS Our results suggest an association between H4R and oral carcinogenesis. Furthermore, our findings raise a potential implication of histamine-mediated factors in the regulation of oncogenes, possibly via mast cells, as crucial components of the tumor microenvironment. The identification of new elements that govern oral cancer development is highly relevant for the development of novel therapeutic approaches in OTSCC.

Abstract
Interleukin-17A (IL-17A), a proinflammatory cytokine mainly produced by T helper 17 cells, exerts protumor or antitumor effects in different cancer entities. However, the exact role of IL-17A in carcinogenesis and progression of tongue squamous cell carcinoma (TSCC) remains unclear. Here, we found that the levels of IL-17A in serum and tumor samples were significantly increased in TSCC patients and positively correlated with tumor metastasis and clinical stage. Besides, IL-17A enhanced cell migration and invasion in SCC15, a TSCC cell line. Furthermore, IL-17A inversely correlated with miR-23b expression in TSCC specimens. In vitro, NF-κB inhibited miR-23b transcription by directly binding to its promoter region. IL-17A downregulated miR-23b expression via activating NF-κB signaling pathway characterized by increasing p65 expression in the nuclear and elevating the levels of p-IKKα and p-IκBα. Overexpression of miR-23b inhibited, whereas knockdown of miR-23b promoted migration and invasion abilities of SCC15 cells. Moreover, extracellular matrix protein versican was proved to be the direct target of miR-23b through luciferase assay. IL-17A increased versican levels in vitro and knockdown of versican by siRNA inhibited SCC15 cell migration and invasion. Taken together, these results reveal a novel mechanism that IL-17A in TSCC microenvironment promotes the migration and invasion of TSCC cells through targeting miR-23b/versican pathway.

Correlation between clinical and MRI assessment of depth of invasion in oral tongue squamous cell carcinoma. J Otolaryngol Head Neck Surg 2016; 45:61. [PMID: 27876067 PMCID: PMC5120480 DOI: 10.1186/s40463-016-0172-0] [Citation(s) in RCA: 64] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2016] [Accepted: 11/01/2016] [Indexed: 01/26/2023] Open
Abstract
Background Neck metastasis is the most important prognostic factor in oral cavity squamous cell carcinomas (SCC). Apart from the T- stage, depth of invasion has been used as a highly predictable factor for microscopic neck metastasis, despite the controversy on the exact depth cut off point. Depth of invasion can be determined clinically and radio logically. However, there is no standard tool to determine depth of invasion preoperatively. Although MRI is used widely to stage the head and neck disease, its utility in depth evaluation has not formally been assessed. Objective To compare preoperative clinical and radiological depth evaluation in oral tongue SCC using the standard pathological depth. To compare clinical and radiological accuracy between superficial (<5 mm) vs. deep invaded tumor (≥5 mm)
Methods This prospective study used consecutive biopsy-proven oral tongue invasive SCC that presented to the University health network (UHN), Toronto. Clinical examination, radiological scan and appropriate staging were determined preoperatively. Standard pathology reports postoperatively were reviewed to determine the depth of invasion from the tumor specimen. Results 72 tumour samples were available for analysis and 53 patients were included. For all tumors, both clinical depth (r = 0.779; p < 0.001) and radiographic depth (r =0.907; p <0.001) correlated well with pathological depth, with radiographic depth correlating slightly better. Clinical depth also correlated well with radiographic depth (r = 0.731; p < 0.001). By contrast, for superficial tumors (less than 5 mm on pathological measurement) neither clinical (r = 0.333, p = 0.34) nor radiographic examination (r = − 0.211; p = 0.56) correlated with pathological depth of invasion. Conclusion This is the first study evaluating the clinical assessment of tumor thickness in comparison to radiographic interpretation in oral cavity cancer. There are strong correlations between pathological, radiological, and clinical measurements in deep tumors (≥5 mm). In superficial tumors (<5 mm), clinical and radiological examination had low correlation with pathological thickness.

Abstract
BACKGROUND The purpose of this study was to evaluate the efficacy and toxicities of proton beam therapy combined with intra-arterial infusion chemotherapy via superficial temporal and occipital arteries for recurrent oral cavity squamous cell carcinoma (SCC). METHODS Between October 2009 and June 2013, 46 patients with recurrent oral cavity SCC were treated by proton beam therapy combined with intra-arterial infusion chemotherapy of cisplatin (CDDP) and docetaxel. Treatment consisted of proton beam therapy (28.6-74.8 GyE in 13-34 fractions) and intra-arterial infusion chemotherapy (CDDP, 30-50 mg/body/week; docetaxel, 5-25 mg/body/week). RESULTS One-year and 2-year overall survival (OS) rates were 65% and 46%, respectively. One-year and 2-year local control rates were 81% and 70%, respectively. CONCLUSION These findings suggest that proton beam therapy combined with intra-arterial infusion chemotherapy could be applied effectively and safely for patients with recurrent oral cavity SCC. © 2016 Wiley Periodicals, Inc.

Abstract
BACKGROUND Of all human oral carcinomas, 41 % are localized to the tongue. Despite considerable improvements in both diagnosis and treatment, tongue squamous cell carcinoma (TSCC) has remained one of the most lethal types of cancer. Here, we aimed at identifying a salivary microRNA (miRNA) expression signature specific for TSCC patients. METHODS To identify putative diagnostic biomarkers, we compared the miRNA expression profiles of saliva samples from three TSCC patients and four healthy control individuals using an Agilent miRNA microarray platform (V19). Three of the differentially expressed miRNAs identified were selected for further validation using quantitative reverse-transcription PCR (qRT-PCR) in saliva samples from 25 TSCC patients and 25 healthy control individuals. RESULTS Through microarray-based expression profiling, we found that 419 miRNAs were deregulated in the saliva samples from the TSCC patients compared to those from the healthy control individuals tested. Subsequent qRT-PCR analysis revealed that the expression level of miR-139-5p was significantly reduced in the TSCC validation samples compared to the controls. Further analysis of post-operative saliva samples derived from TSCC patients revealed that the miR-139-5p expression levels had turned back to normal again. In addition, we found that miR-139-5p exhibited enough power to discriminate pre-operative TSCC patients from both normal individuals (AUC: 0.805) and post-operative TSCC patients (AUC: 0.713), thereby underscoring its diagnostic potential. CONCLUSIONS From our results we conclude that saliva can be used as a feasible source for routine TSCC diagnostics and that miR-139-5p may serve as a potential biomarker for early TSCC detection.

Abstract
OBJECTIVES/HYPOTHESIS The American Joint Committee on Cancer (AJCC) substantially changed the staging of cutaneous squamous cell carcinoma (cSCC) in the seventh edition of its staging manual. Given that oral mucosal squamous cell carcinoma (mSCC) and cSCC behave differently and affect different patient populations, the aim of this study was to provide a side-by-side comparison and to evaluate the current nodal (N) grouping for cSCC alongside oral mSCC to determine whether the same system is justified. STUDY DESIGN Retrospective analysis of prospectively collected data. METHODS Multivariable analysis of 672 patients with metastatic cSCC and of 225 patients with metastatic mSCC from two prospective cancer-center databases. RESULTS While, as expected, the N grouping functioned well in mSCC in terms of distribution and stratification of patients, it performed much less favorably in cSCC. In contrast to mSCC, the different N groups demonstrate much less prognostic importance in cSCC. CONCLUSION Although the introduction of a unified N system for mSCC and cSCC has definite advantages, it does not translate into optimal distribution and stratification for metastatic cSCC. LEVEL OF EVIDENCE 4.

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
PURPOSE The aim of this study was to review the efficacy and toxicity of radiation therapy with concurrent retrograde superselective intra-arterial chemotherapy in the treatment of gingival carcinoma. METHODS AND MATERIALS In all, 34 patients (21 men and 13 women) with squamous cell carcinoma of the gingiva underwent radiation therapy with concurrent retrograde superselective intra-arterial chemotherapy. Treatment consisted of daily external irradiation and concurrent retrograde superselective intra-arterial infusion with cisplatin and docetaxel. A median total dose of 60 Gy in 30 fractions was delivered to tumors. RESULTS Of the 34 patients, 29 (85 %) achieved a complete response (CR) and 5 had residual tumors. Of the 29 patients with a CR, 2 had local recurrences and 1 had distant metastasis 1-15 months after treatment. Twenty-six of the 36 patients had survived at a median follow-up time of 36 months (range 12-79 months); 4 died of cancer and 4 died of non-cancer-related causes. At both 3 and 5 years after treatment, the overall survival rates were 79 % and the cause-specific survival rates were 85 %. Osteoradionecrosis of the mandibular bone only developed in 1 patient after treatment. CONCLUSION Radiation therapy with concurrent retrograde superselective intra-arterial chemotherapy was effective and safe in the treatment of gingival carcinoma. This treatment may be a promising curative and organ-preserving treatment option for gingival carcinoma.

Tumor thickness as an independent risk factor of early recurrence in oral cavity squamous cell carcinoma. Eur Arch Otorhinolaryngol 2013; 271:1747-54.

Abstract
The aim is to determine if tumor thickness is a risk factor related to the development of early recurrences in surgically treated oral cavity squamous cell carcinoma (SCC). Retrospective cohort study conducted at Instituto do Câncer do Estado de São Paulo (ICESP). Fifty-seven patients with oral cavity SCC (excluding lip tumors and patients previously submitted to any treatment) were analyzed regarding the occurrence of an early disease progression (locoregional or distant metastasis) within the first 12 months after initial treatment. Tumor thickness and other histological characteristics related to the development of recurrence up to 1 year after treatment were tested. Results demonstrated that tumor thickness greater than 10 mm (P = 0.034), as well as angiolymphatic invasion (P = 0.001), perineural invasion (P = 0.041) and lymph-node metastasis (P = 0.021) was associated with a worse 12-month disease-free survival (Log-Rank test). In multivariate analysis, tumor thickness greater than 10 mm emerged as an independent risk factor for early recurrence in oral cavity tumors (HR = 3.4, 95% CI: 1.005-11.690; P = 0.049--Cox regression). Post-operative radiotherapy seems to be a protective factor for early recurrences in patients with tumor thickness greater than 10 mm (P = 0.017--Log-Rank test; HR = 0.32, 95% CI: 0.12-0.87, P = 0.026--Cox regression). The results of the present research suggest that tumor thickness greater than 10 mm may be an independent adverse factor for early progression of surgically treated oral cavity SCC. Adjuvant therapies, in particular post-operative radiotherapy, should be advocated in this group of patients, regardless of the co-existence of other well-described histological risk factors.

Abstract
Astrocyte elevated gene-1 (AEG-1) expression is increased in diverse human cancers and plays a vital role in tumorigenesis and progression. The aim of this study was to investigate the clinicopathologic features and prognostic significance of AEG-1 in squamous cell carcinoma of the tongue (TSCC). Immunohistochemistry (IHC) was performed to examine AEG-1 protein expression in paraffin-embedded tissues from 93 patients with TSCC. Real-time PCR and western blot analyses were employed to examine AEG-1 expression in 4 pairs of primary TSCC and adjacent non-cancerous tissues from the same patient. Immunohistochemical results revealed that the positive rate for AEG-1 in TSCC tissues (48.39%, 45/93) was higher than that in the normal tongue tissues (10.00%, 3/30) (P < 0.001). These results were further confirmed between TSCC tissues and matched adjacent non-cancerous tissues by Western blot and RT-PCR. Simultaneously, AEG-1 protein level was positively correlated with differentiation degree (P < 0.001), clinical stage (P < 0.001), T classification (P = 0.007) and N classification (P = 0.012). Furthermore, patients with higher AEG-1 expression had shorter overall survival time. Multivariate analysis (Cox regression) also suggested that AEG-1 expression was an independent prognostic indicator for TSCC (P = 0.043). Our results indicate that AEG-1 expression is closely associated with carcinogenesis and progression of TSCC, and may represent a novel and valuable predictor for prognostic evaluation of TSCC patients.

Abstract
PURPOSE Focal adhesion kinase (FAK) and Src are protein tyrosine kinases, localized in the focal adhesions, which, upon activation interacts each other, regulate several cellular signaling pathways implicated in malignant transformation and disease progression. The present study aimed to evaluate the clinical significance of FAK and Src protein expression in mobile tongue squamous cell carcinoma (SCC). METHODS FAK and Src protein expression was assessed immunohistochemically on 48 mobile tongue SCC tissue samples and was analyzed in relation with clinicopathological characteristics, overall and disease-free patients' survival. RESULTS FAK positivity was noted in 32 (66.67 %) and Src positivity in 45 (93.75 %) out of 48 mobile tongue SCC cases. FAK and Src protein expression was significantly increased in well-differentiated tumors compared to poorly differentiated ones (p = 0.0455 and p = 0.0301, respectively). Mobile tongue SCC patients presenting elevated Src expression showed longer overall and disease-free survival (log-rank test, p = 0.0145 and p = 0.0388, respectively). In multivariate analysis, the depth of invasion proved to be an independent prognostic factor of both overall and disease-free patients' survival (Cox regression, p = 0.0313 and p = 0.0481, respectively), whereas Src expression did not remain significant. CONCLUSIONS The present study supported evidence for a potential role of FAK and Src signaling in mobile tongue SCC, rendering their small-molecule tyrosine kinase inhibitors as possible treatment strategy in tongue cancer chemoprevention.

Abstract
AIMS Metallothionein (MT) has been implicated in several aspects of cancer pathobiology, such as differentiation, proliferation, apoptosis and invasion. The aim of the present study was to evaluate the clinical significance of MT expression in mobile tongue squamous cell carcinoma (SCC). METHODS AND RESULTS MT protein expression was assessed immunohistochemically on 49 mobile tongue SCC specimens, and was analysed in relation to clinicopathological characteristics, and overall and disease-free patient survival. All of the examined mobile tongue SCC cases showed MT positivity in tumour cells; however, neither MT overexpression nor staining intensity was significantly associated with clinicopathological parameters. MT cellular distribution was significantly associated with histopathological grade of differentiation and depth of invasion (P = 0.0188 and P = 0.0484, respectively). MT staining intensity was identified as a significant predictor of overall patient survival at both univariate (P = 0.0377) and multivariate (P = 0.0472) levels. Twenty-seven (55.10%) of the examined SCC cases showed MT positivity in squamous tongue epithelium adjacent to the tumour, the MT positivity being correlated with depth of invasion (P = 0.0281), vascular invasion (P = 0.0194), and the existence of lymph node metastases (P = 0.0194). CONCLUSIONS MT may be implicated in the development and progression of mobile tongue SCC and could be considered as a useful clinical marker for patient management and prognosis.

Abstract
Background The receptor-binding cancer antigen expressed on SiSo cells (RCAS1) is a human tumor-associated antigen that has been considered to play a crucial role in tumor progression by enabling cancer cells to evade immune surveillance. The present study aimed to evaluate the clinical significance of RCAS1 expression in mobile tongue squamous cell carcinoma (SCC). Material/Methods RCAS1 protein expression was assessed immunohistochemically on 49 mobile tongue SCC tissue samples obtained from an equal number of patients and was statistically analyzed with clinicopathological characteristics and overall and disease-free patients’ survival. Results Enhanced RCAS1 expression was significantly associated with reduced depth of invasion (p=0.0069), low mitotic index (p=0.0251) and no evidence of muscular invasion (p=0.0098). A borderline association between RCAS1 expression and stromal inflammatory reaction was also noted (p=0.0660). RCAS1 expression was not associated with overall and disease-free survival. Conclusions Our data support evidence for possible implication of RCAS1 at the early stage of tumor progression in mobile tongue SCC, whereas the survival prediction using RCAS1 expression as a clinical marker seems uncertain for this type of malignancy.

Abstract
UNLABELLED Squamous cell carcinoma of the tongue (TSCC) has one of the poorest prognoses of head and neck cancers. This study aims to improve early detection of the disease by identifying salivary biomarkers that can identify a spectrum of patients progressing from high-risk to TSCC. We also examine the mortality of exophytic and endophytic TSCC, expecting the elevated cytokine levels in endophytic patients to be associated with a shorter survival. Saliva was collected from patients with TSCC and controls and cytokine protein levels were measured. Specimens were collected from the Los Angeles County (LAC) + University of Southern California (USC) and USC University Hospital clinics. A convenience sample of patients with TSCC was divided into endophytic (n=10) and exophytic (n=8) cancer by physician diagnosis. Controls were divided into 4 groups of 14 based on their high-risk smoking and drinking behaviors. MAIN OUTCOME MEASURES The levels of IL-1α, IL-6, IL-8, VEGF-a and TNF-α in saliva were measured using quantitative ELISA and compared using two-way ANOVA. All five cytokines were elevated in the endophytic TSCC group compared to other groups, which correlated with the decreased survival rate (10.4 months) in this group compared to exophytic TSCC (24 months). IL-1α, IL-6, TNF-α and VEGF were also elevated in the exophytic TSCC group compared to smoking-drinking controls. Salivary levels of IL-1α, IL-6, IL-8, VEGF-a and TNF-α can identify the progression of TSCC from high-risk to neoplasm, serving as potential biomarkers for cancer screening and early detection. The correlation with survival implies a prognostic benefit and could serve as a tool for management decisions and future treatment targets.

Abstract
PURPOSE Peroxisome proliferator-activated receptor-γ (PPAR-γ) is a ligand-activated transcription factor, implicated in various aspects of cancer biology, such as differentiation, proliferation, invasion and angiogenesis. The present study aimed to evaluate the clinical significance of PPAR-γ in mobile tongue squamous cell carcinoma (SCC). METHODS PPAR-γ protein expression was assessed immunohistochemically on 49 mobile tongue SCC tissue samples obtained from an equal number of patients. PPAR-γ expression and intensity of immunostaining were statistically analyzed in relation with clinicopathological characteristics, mitotic index and patients' survival. RESULTS Elevated PPAR-γ expression was more frequently observed in patients with reduced depth of invasion (P = 0.0111). Moderate/intense PPAR-γ staining intensity was more frequently observed in patients with no evidence of muscular infiltration (P = 0.0229) and reduced depth of invasion (P = 0.0176). Mobile tongue SCC patients presenting enhanced PPAR-γ expression had significantly longer overall and disease-free survival times compared to those with low PPAR-γ expression (log-rank test, P = 0.0162 and P = 0.0114, respectively). CONCLUSIONS PPAR-γ immunoreactivity in mobile tongue SCC was correlated with clinicopathological characteristics crucial for patients' management and prognosis. PPAR-γ may be considered as a useful prognostic marker in mobile tongue SCC and a potential therapeutic target for tongue cancer chemoprevention and treatment.

Abstract
BACKGROUND Histone deacetylases (HDACs) have been associated with tumor development and progression in several types of human malignancy and HDAC inhibitors are currently being explored as anti-cancer agents in clinical trials. The aim of the present study was to evaluate the clinical significance of HDAC-1 and -2 protein expression in mobile tongue squamous cell carcinoma (SCC). METHODS HDAC-1 and -2 protein expression was assessed immunohistochemically on 49 mobile tongue SCC tissue samples and was analyzed in relation with clinicopathological characteristics, overall and disease-free patients' survival. RESULTS HDAC-1 overexpression was significantly associated with younger patients' age (P = 0.0381) and male gender (P = 0.0345), poor histopathological grade of differentiation (P = 0.0236) and the presence of lymph node metastases (P = 0.0104). Intense HDAC-1 staining intensity was significantly associated with male gender (P = 0.0127), increased stromal infiltration reaction (P = 0.0125) and well-defined shape of tumor invasion (P = 0.0396). HDAC-2 overexpression did not show significant correlations with any clinicopathological parameters, whereas intense HDAC-2 staining intensity was significantly associated with the presence of muscular invasion (P = 0.0466) and advanced depth of invasion (P = 0.0251). Mobile tongue SCC patients with HDAC-1 overexpression presented shorter overall and disease-free survival compared to those with no evidence of HDAC-1 overexpression (log-rank test, P = 0.0651 and 0.0247, respectively). CONCLUSIONS The present study supported evidence that HDACs may participate in the formation and progression of mobile tongue SCC, reinforcing their possible use as biomarkers as also the therapeutic utility of HDAC inhibitors in mobile tongue SCC chemoprevention and treatment.

Abstract
BACKGROUND AND PURPOSE Small oral cavity tumors are an imaging challenge. Intimate apposition of vestibular oral mucosa to the alveolar mucosa makes tumor assessment difficult. In CT imaging, the "puffed cheek" method has been used to separate surfaces, though this is not feasible with long MR imaging sequences. We implemented placement of 2 × 2 inch (6.45 cm) gauze into the oral vestibule before the MR imaging examination, to determine whether this might improve tumor visualization. MATERIALS AND METHODS MR imaging examinations of all T1 oral malignant tumors treated at University of California, San Francisco, by the Oral and Maxillofacial Department were reviewed by 2 neuroradiologists. Nine patients were included in the final analysis. Six patients were imaged by using a standard protocol. Three patients were imaged with gauze placement. The radiologists evaluated the MR images, assessing whether they could see the tumor and then fully delineate it and its thickness. RESULTS Fisher exact analysis was performed on questions 1, 2, and 4 with the following results: P value = .048, Can you see the tumor? P value = .012, Can you fully delineate? P value of .012, How confident are you? MR imaging examinations with gauze clearly delineated the tumor with the tumor thickness measurable. MR imaging examinations without gauze did not clearly show the tumor or its thickness. Confidence of interpretation of the findings was also increased when gauze was used. CONCLUSIONS A 2 × 2 inch (6.45 cm) rolled gauze in the oral vestibule significantly improved tumor localization and delineation at MR imaging. This technique is simple and provides superior preoperative imaging evaluation and treatment planning of small oral cavity tumors.

Abstract
BACKGROUND DNA repair is a major defense mechanism, which contributes to the maintenance of genetic sequence, minimizing cell death, mutation rates, replication errors, DNA damage persistence and genomic instability. Alterations of proteins participating in DNA repair mechanisms have been associated with several aspects of cancer biology. The present study aimed to evaluate the clinical significance of DNA repair proteins, MSH2, MLH1 and MGMT in mobile tongue squamous cell carcinoma (SCC). METHODS MSH2, MLH1 and MGMT protein expression was assessed immunohistochemically on 49 mobile tongue SCC tissue samples and was analyzed in relation with clinicopathological characteristics, overall and disease-free patients' survival. RESULTS MSH2 expression was significantly associated with depth of invasion (P=0.0335), tumor shape (P=0.0396) and muscular invasion (P=0.0098). MLH1 expression was significantly associated with lymph node metastases (P=0.0484) and borderline with perineural invasion (P=0.0699). MGMT expression was significantly associated with depth of invasion (P=0.0472), tumor shape (P=0.0187), perineural invasion (P=0.0115) and lymph node metastases (P=0.0032) and borderline with vascular invasion (P=0.0755). MSH2 expression was significantly associated with disease-free patients' survival in univariate analysis (P=0.0441), being also identified as an independent prognostic factor in multivariate analysis (P=0.0451). CONCLUSIONS The present study supported evidence for possible implication of MSH2, MLH1 and MGMT proteins in the formation and progression of mobile tongue SCC.

Abstract
BACKGROUND Squamous cell carcinoma (SCC) of the oral tongue is well known to be an aggressive disease with early metastatic spread in early stage tumors. It is also established that locoregional recurrences are the main causes of treatment failure. Thus, the identification of histopathological factors possessing a predictive value remains important for the management of the disease. The aim of the present study was to define histopathological parameters of the tumor and to compare with the follow-up and status in primary SCCs of the mobile tongue. METHODS Histopathological parameters such as mitotic index, the presence of vascular emboli or perineural invasion, the thickness of the tumor, the histological grade, the tumor shape as well as chronic stromal inflammatory infiltration were assessed in 52 patients with SCC of the mobile tongue and compared with the follow-up and status in patients treated initially by surgery. RESULTS Tumor shape was significantly associated with the presence of perineural invasion. Well-defined shaped tumors displayed almost half the incidence of perineural invasion when compared with ill-defined shaped tumors. In addition, the high density of the chronic inflammatory infiltration of the stroma exhibited significant correlation with the survival of the patients. Finally, the intense chronic inflammatory infiltration of the stroma was associated with well-defined shaped tumors. CONCLUSION Tumor shape and stromal chronic inflammatory infiltration should be considered in the planning of the management of patients with SCC of the mobile tongue.

Abstract
Oral cancer represents a common entity comprising a third of all head and neck malignant tumors. The options for curative treatment of oral cavity cancer have not changed significantly in the last three decades; however, the work up, the approach to surveillance, and the options for reconstruction have evolved significantly. Because of the profound functional and cosmetic importance of the oral cavity, management of oral cavity cancers requires a thorough understanding of disease progression, approaches to management and options for reconstruction. The purpose of this review is to discuss the most current management options for oral cavity cancers.
