Abstract
BACKGROUND Oral squamous cell carcinoma (OSCC) is the most common malignant neoplasms of the oral cavity. Tongue, buccal mucosa, and gingivobuccal sulcus are the most commonly involved sites for the local recurrence of OSCC. The site of the tumor can be a critical parameter in relation to the recurrence of OSCC because of the varied action of tumor cells in different tumor macro and microenvironments. Hence, the current study aims to evaluate the correlation between the site and recurrence of OSCC among patients visiting private oral cancer hospitals. MATERIALS AND METHODS Details of n=300 OSCC cases reported during 2019-2023, which included primary and recurrent OSCC, were collected. The sample population selected includes 261 primary and 39 recurrent oral squamous cell carcinoma cases. The demographic and clinicopathological data were retracted from the institution's common clinical database and transported to IBM-SPSS 23 software for statistical analysis. Chi-square was done to evaluate the association between site and recurrence status, and p<0.05 was considered statistically significant. RESULTS Males have a high predilection for OSCC, and the recurrent cases account for 13% of the sample population. The buccal mucosa was the most commonly affected site in primary and recurrent OSCC cases. However, the association between the site of the lesion and the status of recurrence was found to be statistically significant, with a p-value of 0.001. CONCLUSION Even though buccal mucosa was the most common site for recurrent OSCC(p value-0.001), the present study carries a small sample size and a location-specific sampling. Hence, further studies must be conducted with a large sample size to test the significant correlation between the site and recurrence rate among patients diagnosed with OSCC.

Perineural Invasion Is a Significant Prognostic Factor in Oral Squamous Cell Carcinoma: A Systematic Review and Meta-Analysis. Diagnostics (Basel) 2023; 13:3339. [PMID: 37958235 PMCID: PMC10649820 DOI: 10.3390/diagnostics13213339] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Revised: 10/17/2023] [Accepted: 10/26/2023] [Indexed: 11/15/2023] Open
Abstract
(1) Objectives: This systematic review and meta-analysis aimed to summarize current evidence regarding the prognostic role of perineural invasion (PNI) in patients with oral squamous cell carcinoma (OSCC). (2) Methods: We searched Cochrane Central, ProQuest, PubMed, Scopus, Science Direct, and Web of Science, using relevant keywords to identify eligible articles. Two independent reviewers conducted two-stage screening, data extraction, and quality assessment. The risk of bias was assessed using the Newcastle-Ottawa Scale (NOS) criteria. All analyses were performed using comprehensive meta-analysis (CMA; version 3.3.070) software. (3) Results: The study included 101 published articles encompassing 26,062 patients. The pooled analyses showed that PNI was associated with significantly worse overall survival (OS; HR = 1.45, 95% CI: 1.32-1.58; p < 0.001), worse disease-specific survival (DSS; HR = 1.87, 95% CI: 1.65-2.12; p < 0.001), and worse disease-free survival (DFS; HR = 1.87, 95% CI: 1.65-2.12; p < 0.001). Similarly, both local recurrence-free survival (LRFS) and regional recurrence-free survival (RRFS) were worse in patients with PNI (HR = 2.31, 95% CI: 1.72-3.10, p < 0.001; and HR = 2.04, 95% CI: 1.51-2.74, p < 0.001), respectively. The random-effect estimate of three studies demonstrated that the presence of PNI was associated with worse failure-free survival (FFS; HR = 2.59, 95% CI: 1.12-5.98, p < 0.001). (4) Conclusions: The current evidence suggests that PNI can be used as an independent predictor of the prognosis for patients with OSCC. The presence of PNI was associated with worse OS, DFS, DSS, FFS, and with recurrence. Asian patients and patients with extra-tumoral or peripheral PNI invasion were associated with worse prognosis.

Abstract
Background Tongue carcinomas account for 25%-40% of intraoral squamous cell carcinomas (OSCCs). Although TNM staging systems is an international standard for cancer reporting, prognosis evaluation, and treatment planning, multiple histopathological risk assessment predictors such as tumor thickness (TT), tumor shape, tumor growth pattern, and invasive malignancy grading scoring systems have been studied and should form a basis for prediction and prognostication of such aggressive carcinomas. Aim To evaluate and characterize the histomorphological prognostic indicators in OSCCs of tongue and compare it with OSCCs of other anatomic sites within the oral cavity. Furthermore, to elucidate the significance of histopathological indicators in predicting prognosis of tongue squamous cell carcinomas (SCCs). Materials and Methods Forty SCC cases with 20 each of tongue and 20 from other intraoral sites were retrieved from department archives. Clinical data and staging were obtained for each case. Histomorphological parameters including pattern of invasion (POI), tumor budding (TB), depth of invasion (DOI), TT, lymphocytic host response, tumor-associated tissue eosinophilia (TATE), vascular invasion, perineural invasion (PNI), and muscular invasion were assessed. The results were statistically evaluated. Results TB, DOI, and sarcolemmal spread were significant histologic predictors in tongue SCC. Upon correlation of histomorphological parameters with clinical staging, TT, POI, and TATE were observed to be significantly correlated (P ≤ 0.05). Conclusion The histomorphological risk assessment model may serve as important addition to the existing prognosticators and may be used as a prognostic index to help plan and individualize treatment protocol in cases with aggressive high-risk disease for whom the use of multimodality treatment seems beneficial.

Prognostic Value of Perineural Invasion on Survival and Recurrence in Oral Squamous Cell Carcinoma. Diagnostics (Basel) 2022; 12:diagnostics12051062. [PMID: 35626218 PMCID: PMC9139854 DOI: 10.3390/diagnostics12051062] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2022] [Revised: 04/20/2022] [Accepted: 04/21/2022] [Indexed: 12/22/2022] Open
Abstract
A diagnosis of perineural invasion (PNI) is widely accepted as an unfavorable prognostic factor in various solid malignancies. Although PNI has been described as a high-risk parameter in oral squamous cell carcinoma (OSCC), its role in the current staging manuals of the American Joint Committee on Cancer (AJCC) is rather subordinate. We analysed the prognostic value of PNI on survival and recurrence in a large, multicenter OSCC cohort and a population-based approach. A total of 493 OSCC patients with primary tumor resection to negative margins and concomitant neck dissection between 2010 and 2017 were enrolled. PNI was evaluated in relation to overall survival (OAS) and recurrence-free survival (RFS) using uni- and multi-variable Cox regression. The median follow-up time was 5.0 years and PNI was diagnosed in 48 patients (9.7%). A pathohistological verification of PNI correlated significantly with a deteriorated OAS in uni- (HR 2.312; 95% CI 2.312–3.493, p = 0.001) and multivariable Cox regression (HR 1.820; 95% CI 1.164–2.847, p = 0.009). Additionally, a diagnosis of PNI correlated with increased cumulative, as well as distant, metastasis 5-year-recurrence rates (p = 0.027 and p = 0.011, respectively). The application of adjuvant radiotherapy (RT) or radiochemotherapy (RCT) in patients with PNI did not alter OAS or RFS in survival analysis when compared to patients without PNI. The results underline the adverse impact of PNI on the survival and recurrence of surgically treated OSCC patients. Based on our findings, we highly recommend an emphasis on PNI in the TNM staging concept.

Abstract
Introduction Numerous studies have evaluated the prognostic significance of perineural invasion (PNI) in oral cancer; however, the results are inconclusive. Purpose To identify the prognostic value of PNI in oral cancer through a metanalysis. Methods A literature review was carried out, searching the MedLine databases via Pubmed, Scielo, Lilacs, Cochrane and Websco. Results A total of 56 studies were included. The results indicate that PNI in oral cancer has an incidence of 28% (95% confidence interval (CI) 24-31%); 5-year survival with relative risk (RR) 0.67 (0.59-0.75); 5-year disease-free survival RR 0.71 (0.68-0.75); locoregional recurrence with RR 2.09 (1.86-2.35). Conclusions PNI is a negative prognostic factor in oral cancer.

Abstract
Oral cancer is a common human malignancy that still maintains an elevated mortality rate despite scientific progress. Tumorigenesis is driven by altered gene expression patterns of proto-oncogenes and tumor-suppressor genes. MicroRNAs, a class of short non-coding RNAs involved in gene regulation, seem to play important roles in oral cancer development, progression, and tumor microenvironment modulation. As properties of microRNAs render them stable in diverse liquid biopsies, together with their differential expression signature in cancer cells, these features place microRNAs at the top of promising biomarkers for diagnostic and prognostic values. In this review, we highlight eight expression levels and functions of the most relevant microRNAs involved in oral cancer development, progression, and microenvironment sustainability. Furthermore, we emphasize the potential of using these small RNA species as non-invasive biomarkers for the early detection of oral cancerous lesions. Conclusively, we highlight the perspectives and limitations of microRNAs as novel diagnostic tools, as well as therapeutic models.

Abstract
The comparison of chemical and histopathological data obtained from the analysis of excised tumor fragments oral squamous cell carcinoma (OSCC) with the demographic and clinical evolution data is an effective strategy scarcely explored in OSCC studies. The aim was to analyze OSCC tissues for protein expression of enzymes related to oxidative stress and DNA repair and trace elements as candidates as markers of tumor aggressiveness and prognosis. Tumor fragments from 78 OSCC patients that had undergone ablative surgery were qualitatively analyzed by synchrotron micro-X-ray fluorescence for trace elements. Protein expression of SOD-1, Trx, Ref-1 and OGG1/2 was performed by immunohistochemistry. Sociodemographic, clinical, and histopathological data were obtained from 4-year follow-up records. Disease relapse was highest in patients with the presence of chlorine and chromium and lowest in those with tumors with high OGG1/2 expression. High expression of SOD-1, Trx, and Ref-1 was determinant of the larger tumor. Presence of trace elements can be markers of disease prognosis. High expression of enzymes related to oxidative stress or to DNA repair can be either harmful by stimulating tumor growth or beneficial by diminishing relapse rates. Interference on these players may bring novel strategies for the therapeutic management of OSCC patients.

Abstract
OBJECTIVES A significant number of recently published research has outlined the contribution of perineural invasion (PNI) to clinical outcomes in oral tongue squamous cell carcinoma (OTSCC), but some results remain conflicting. This study aimed to determine whether patients with OTSCC with PNI have a worse prognosis than those without PNI. MATERIALS AND METHODS PubMed, Embase, and the Cochrane Library were queried for potentially eligible articles published up to December 2020. The primary outcomes were the hazard ratio (HR) for locoregional recurrence, overall survival (OS), disease-free survival (DFS), and cancer-specific survival (CSS). The random-effect model was used in all analyses. RESULTS Seventeen studies (4445 patients) were included. Using adjusted HRs, the presence of PNI was associated with a higher risk of locoregional recurrence (HR=1.73, 95%CI: 1.07-2.79, P=0.025, I2 = 33.1%, Pheterogeneity=0.224), worse OS (HR=1.94, 95%CI: 1.39-2.72, P<0.001, I2 = 0.0%, Pheterogeneity=0.838), worse DFS (HR=2.13, 95%CI: 1.53-2.96, P<0.001, I2 = 48.4%, Pheterogeneity=0.071), and worse CSS (HR=1.93, 95%CI: 1.40-2.65, P<0.001, I2 = 25.5%, Pheterogeneity=0.251). PNI had an impact on locoregional recurrence in early-stage OTSCC but not in all stages, and on OS, DFS, and CSS in all-stage and early-stage OTSCC. The sensitivity analyses showed that the results were robust. CONCLUSION The presence of PNI significantly affects the locoregional recurrence and survival outcomes among patients with OTSCC.

Abstract
BACKGROUND Perineural invasion (PNI) and lymphovascular invasion (LVI) may be adverse prognostic indicators in squamous cell carcinoma (SCC) of the tongue. METHODS The percentages of histological PNI and LVI were determined in 335 patients with tongue SCC. Sixty tumours originally reported as negative for these features were tested to determine how many more were positive with "immunohistochemical enhancement." RESULTS PNI was found in 141 (42.1%) and LVI in 51 (15.2%) patients. 79.4% of the 141 patients who had PNI and 72.6% of the 51 with LVI had a T3 or T4 tumour. Lymph node metastasis was identified in 145 (51.2%) of the 280 patients who had undergone neck dissection; 58.2% of the 141 patients with PNI and 80.4% of the 51 patients with LVI had lymph node metastasis. There was a highly statistically significant correlation between PNI with increasing pT (P < .00001) and pN (P < .0001) stage, and a statistically significant correlation between LVI and pT stage (P < .001), the association of LVI with pN status could not be reliably tested statistically. Immunohistochemistry for S100 identified five further cases of PNI, but review of the original H&E showed the feature was present in four and had been missed at original reporting. CD31 identified three further possible cases of LVI and D2-40 none. The endothelium of some vascular channels was positive for both CD31 and D2-40 and cross-reactivity with other cells compromised interpretation. CONCLUSIONS Histological identification of PNI and LVI per se remains of uncertain prognostic significance. "Immunohistochemical enhancement" offered little benefit.

Histopathologic prognostic indices in tongue squamous cell carcinoma. Eur Arch Otorhinolaryngol 2020; 278:2461-2471. [PMID: 32897441 DOI: 10.1007/s00405-020-06329-5] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2020] [Accepted: 08/28/2020] [Indexed: 10/23/2022]
Abstract
PURPOSE Consistent prognosticators are needed to guide adjuvant treatment in tongue squamous cell carcinoma (SCC). We validate the prognostic significance of histopathologic parameters in surgically treated tongue SCC. METHODS Archival specimens of 88 consecutive patients who were treated surgically for tongue SCC from 2003 to 2016 were re-analyzed by one pathologist. Patient records were retrospectively reviewed. Prognosticators of recurrence-free survival (RFS), overall survival (OS), and disease-specific survival (DSS) were identified using multivariate analysis. RESULTS Tumor depth of invasion (DOI) > 6 mm (OR 4.76; 95%CI 1.22-18.5; p = 0.024) and lymphovascular invasion (OR 5.61; 95%CI 1.00-31.5; p = 0.05) were independent predictors of nodal metastases. The overall 5-year RFS, OS and DSS were 70%, 82% and 84% respectively. Positive margins predicted poor RFS (HR 3.91; 95%CI 1.58-9.65; p = 0.003) and local recurrence-free survival (HR 4.96; 95%CI 1.36-18; p = 0.015). Presence of nodal metastases (HR 5.03; 95%CI 1.73-14.6; p = 0.003), tumor DOI > 6 mm (HR 9.91; 95%CI 1.26-78.0; p = 0.029) and positive margins (HR 8.26; 95%CI 2.75-24.8; p < 0.001) were independent predictors of poor OS. Presence of nodal metastases (HR 3.87; 95%CI 1.17-12.8; p = 0.027) and positive margins (HR 12.3; 95%CI 3.54-42.9; p < 0.001) also independently predicted poor DSS. CONCLUSION Margins' status was the only independent predictor of local recurrence. Tumor DOI, nodal and margin status were key prognosticators of survival and may determine the necessity for adjuvant therapy.

A Proposal to Revise the Histopathologic Grading System of Early Oral Tongue Cancer Incorporating Tumor Budding. Am J Surg Pathol 2020; 43:703-709.

Abstract
The World Health Organization (WHO) grading system has a low prognostic value for early-stage oral tongue squamous cell carcinoma; greater prognostic power has been shown with tumor budding analysis. In this study, we combined tumor budding analysis with histopathologic grading according to WHO 2017. In our proposal, a revised grade I tumor is defined as a "well differentiated cohesive tumor"; revised grade II as a "moderately differentiated and/or slightly dissociated tumor"; and revised grade III as a "poorly differentiated and/or dissociated tumor." We evaluated the prognostic value of this proposed grading system in a multicenter cohort of 311 cases of early oral tongue squamous cell carcinoma. The proposed grading system showed significant prognostic value in multivariable analysis for disease-specific survival with a hazard ratio of 3.86 and a 95% confidence interval of 1.36-10.9 (P=0.001). For disease-free survival, the proposed grading system showed good predictive power in multivariable analysis (hazard ratio, 2.07; 95% confidence interval, 1.00-4.27; P=0.009). The conventional WHO grading system showed a low prognostic value for disease-specific survival and disease-free survival (P>0.05). In conclusion, the prognostic power of the WHO histopathologic grading improved significantly with incorporation of tumor budding. Our proposed grading system can be easily included in pathology reports.

A panel of Transcription factors identified by data mining can predict the prognosis of head and neck squamous cell carcinoma. Cancer Cell Int 2019; 19:297. [PMID: 31787845 PMCID: PMC6858662 DOI: 10.1186/s12935-019-1024-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2019] [Accepted: 11/11/2019] [Indexed: 11/13/2022] Open
Abstract
Background Transcription factors (TFs) are responsible for the regulation of various activities related to cancer like cell proliferation, invasion, and migration. It is thought that, the measurement of TFs levels could assist in developing strategies for diagnosis and prognosis of cancer detection. However, due to lack of effective genome-wide tests, this cannot be carried out in clinical settings. Methods A complete assessment of RNA-seq data in samples of a head and neck squamous cell carcinoma (HNSCC) cohort in The Cancer Genome Atlas (TCGA) database was carried out. From the expression data of six TFs, a risk score model was developed and further validated in the GSE41613 and GSE65858 series. Potential functional roles were identified for the six TFs via gene set enrichment analysis. Results Based on our multi-TF signature, patients are stratified into high- and low-risk groups with significant variations in overall survival (OS) (median survival 2.416 vs. 5.934 years, log-rank test P < 0.001). The sensitivity and specificity evaluation of our multi-TF for 3-year OS in TCGA, GSE41613 and GSE65858 was 0.707, 0.679 and 0.605, respectively, demonstrating good reproducibility and robustness for predicting overall survival of HNSCC patients. Through multivariate Cox regression analyses (MCRA) and stratified analyses, we confirmed that the predictive capability of this risk score (RS) was not dependent on any of other factors like clinicopathological parameters. Conclusions With the help of a RS obtained from a panel of TFs expression signatures, effective OS prediction and stratification of HNSCC patients can be carried out.

Abstract
OBJECTIVES This study aimed to evaluate the adverse clinicopathologic features of oral squamous cell carcinoma (OSCC), including margin status, depth of invasion, lymphovascular invasion, perineural invasion, and extranodal extension that significantly affect survival outcomes. MATERIALS AND METHODS This retrospective cross-sectional study included 341 patients with OSCC who underwent therapeutic surgical treatment in Taiwan. The Kaplan-Meier method was used to estimate survival outcomes. A multivariable Cox regression model was used to evaluate the associations of various clinicopathologic features with 5-year overall survival (OS) outcomes in patients with pN0 and pN+ tumors. RESULTS Overall, the patients had 5-year OS and progression-free survival rates of 60.0 and 47.9%, respectively. In the pN0 group, the multivariate analysis identified a positive margin (odds ratio [OR] = 16.3, 95% confidence interval [95% CI]: 3.7-72.3; P = 0.001), depth of invasion >5 mm (OR = 2.1, 95% CI: 1.2-3.7; P = 0.012), presence of lymphovascular space invasion (OR = 5.4, 95% CI: 1.3-22.0; P = 0.018), and presence of perineural invasion (OR = 4.3, 95% CI: 1.7-11.1; P = 0.002) as independent and significant prognosticators of OS. In the pN+ group, only the presence of extranodal extension independently predicted OS (OR = 1.7, 95% CI: 1.1-2.7; P = 0.0026). CONCLUSIONS When determining survival prognosis for patients with a pN0 status, we recommended including all adverse features. In contrast, extranodal extension was the most important prognostic factor for patients with a pN+ status.

[PMID: 30927266 DOI: 10.1002/jcp.28517] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2018] [Revised: 02/21/2019] [Accepted: 03/06/2019] [Indexed: 12/19/2022]
Abstract
Recent evidence suggests that long noncoding RNAs (lncRNAs) are essential regulators of many cancer-related processes, including cancer cell proliferation, invasion, and migration. There is thus a reason to believe that the detection of lncRNAs may be useful as a diagnostic and prognostic strategy for cancer detection, however, at present no effective genome-wide tests are available for clinical use, constraining the use of such a strategy. In this study, we performed a comprehensive assessment of lncRNAs expressed in samples in the head and neck squamous cell carcinoma (HNSCC) cohort available in The Cancer Genome Atlas database. A risk score (RS) model was constructed based on the expression data of these 15 lncRNAs in the validation data set of HNSCC patients and was subsequently validated in validation data set and the entire data set. We were able to stratify patients into high- and low-risk categories, using our lncRNA expression panel to determine an RS, with significant differences in overall survival (OS) between these two groups in our test set (median survival, 1.863 vs. 5.484 years; log-rank test, p < 0.001). We were able to confirm the predictive value of our 15-lncRNA signature using both a validation data set and a full data set, finding our signature to be reproducible and effective as a means of predicting HNSCC patient OS. Through the multivariate Cox regression and stratified analyses, we were further able to confirm that the predictive value of this RS was independent of other predictive factors such as clinicopathological parameters. The Gene set enrichment analysis revealed potential functional roles for these 15 lncRNAs in tumor progression. Our findings indicate that an RS established based on a panel of lncRNA expression signatures can effectively predict OS and facilitate patient stratification in HNSCC.

Abstract
IFIT1 and IFIT3 are abundant products of interferon-stimulating genes. While the importance of IFIT1 and IFIT3 in the prognosis of cancer has been reported, the molecular basis of IFIT1 and IFIT3 in cancer progression remains unexplored. In the present study, we investigated the modes of action and the clinical significance of IFIT1 and IFIT3 in oral squamous cell carcinoma (OSCC). Ectopic expression of IFIT1 or IFIT3 induced OSCC cell invasion by promoting the epithelial-mesenchymal transition, whereas IFIT1 or IFIT3 knockdown exhibited opposite effects. Overexpression of IFIT1 or IFIT3 promoted tumor growth, regional and distant metastasis in xenograft and orthotopic nude mice models. Most importantly, IFIT1 or IFIT3 overexpression increased the levels of p-EGFRY1068 and p-AKTS473 in OSCC cells and also enhanced tumor inhibitory effect of gefitinib. By immunoprecipitation and LC-MS/MS analysis, we found that IFIT1 and IFIT3 interacted with ANXA2 that enhanced p-EGFRY1068 endosomal recycling. Depletion of ANXA2 using siRNA therefore abolished p-EGFRY1068 and p-AKTS473 expression in IFIT1- or IFIT3-overexpressed cells. Furthermore, a significant positive association of increased IFIT1 and IFIT3 expression with advanced T-stage, lymph node metastasis, perineural invasion, lymphovascular invasion, extranodal extension, and poor overall survival rate was confirmed in OSCC patients. We also found a statistically positive correlation of p-EGFRY1068 expression with IFIT1 and IFIT3 in OSCC tumors and poor clinical outcome in patients. Collectively, we demonstrated a novel role of IFIT1 and IFIT3 in driving OSCC progression and metastasis by interacting with ANXA2 and hence enhancing p-EGFR recycling and its downstream signaling.

Abstract
Objectives of the Review The decision whether to include postoperative radiotherapy on patients with oral squamous cell carcinoma depends on the risk of local recurrence. The objectives of this study were to systematically review literature on whether perineural invasion in oral squamous cell carcinoma patients is associated with higher local recurrence rates and whether local recurrence is influenced by the administration of postoperative radiotherapy in patients presenting with perineural invasion. Type of Review Systematic review. Search Strategy Embase, PubMed, Web Of Science. Evaluation Method The databases above were searched for studies that analysed: the treatment of oral squamous cell carcinoma patients with perineural invasion, local recurrence and postoperative radiotherapy. The data of seven studies were analysed qualitatively. Results The overall quality of the studies was moderate to low. There was no evidence of the effect of postoperative radiotherapy on local recurrence rates in patients presenting with perineural invasion. Some evidence suggests that local recurrence rates may increase in cases of multifocal perineural invasion, especially if nerves >1 mm are involved but these data should be interpreted with caution due to the low‐quality evidence. Conclusions High‐quality evidence regarding the prognostic value of perineural invasion and the impact of postoperative radiotherapy in patients presenting with perineural invasion is lacking in the literature, making it difficult to select a postoperative strategy for early‐stage tumours.

Abstract
The cancer microenvironment (CME) promotes malignant progression of cancer cells by stimulating cell growth, migration and invasion. Cancer-associated fibroblasts (CAFs), prominent features of the CME, interact directly with cancer cells and facilitate epithelial-mesenchymal transition (EMT). The present study examined the spatial distribution of CAFs and EMT on cancer cells in patients with early-stage tongue squamous cell carcinoma (TSCC) and their association with local recurrence. The present study included 14 patients with early-stage TSCC who had undergone glossectomy between 2006 and 2015, of which 7 experienced local recurrence (LR group) and 7 did not (control group). Multiple immunofluorescent analysis (MIA) of PCNA, αSMA, vimentin, E-cadherin and cytokeratin 14 (CK14) was performed on slides obtained from surgical specimens to identify the expression of various cell-specific markers. The number of CAFs in the CME was significantly increased in the LR group (P=0.001). Furthermore, the neighbouring cancer cells were positive for vimentin expression, indicating EMT. However, the present study also identified concurrent expression of CK14 in all vimentin-positive cancer cells, whilst epithelial markers, including E-cadherin, were expressed in certain vimentin-positive cancer cells. Concurrent expression of CK14 and vimentin is not defined as EMT or partial EMT. Therefore, the present study proposed a novel mechanism of anaplastic transition (APT), in which epithelial cancer cells concurrently develop mesenchymal features, which is achieved by pathways other than EMT. APT is characterized such that epithelial cancer cells differentiate into more primitive states, which is different from EMT or partial EMT, and it may be associated with LR. The concept aids in improving knowledge regarding tumor recurrence in patients with early-stage TSCC.

Abstract
BACKGROUND Although perineural invasion (PNI) has been recognized as a poor prognostic factor for oral cancer, few studies have focused on tongue squamous cell carcinoma (TSCC). Using a prospective randomized trial, this study investigated the role of PNI in the regional control and survival of the patients with cT1-2N0 TSCC, and clarified the benefit of neck management based on PNI status. METHODS PNI status was reviewed under H&E staining in tumors of 221 patients with cT1-2N0 TSCC, who were randomly assigned into elective neck dissection (END) group (n = 111) and observation group (n = 110). Oncologic and survival outcomes were analyzed by multivariate regression and Kaplan-Meier analyses. RESULTS PNI was identified in 34 patients and multivariate analyses revealed that PNI remained an independent predictor for cervical lymph node metastasis (CLNM), local relapse, neck relapse and disease-specific survival (DSS) after controlling for T stage and pathologic differentiation. END could not improve the benefit for patients. Stratified analysis revealed that END also could not improve neck control or DSS among patients with PNI. CONCLUSIONS This study demonstrated that PNI was an invaluable pathological parameter to independently predict cervical metastasis, local relapse, neck relapse and poor survival outcomes, but END could not improve benefits compared to observation for the PNI-positive patients.

Abstract
Cancer remains as one of the leading cause of death worldwide. The development of cancer involves an intricate process, wherein many identified and unidentified factors play a role. Although most studies have focused on the genetic abnormalities which initiate and promote cancer, there is overwhelming evidence that tumors interact within their environment by direct cell-to-cell contact and with signaling molecules, suggesting that cancer cells can influence their microenvironment and bidirectionally communicate with other systems. However, only in recent years the role of the nervous system has been recognized as a major contributor to cancer development and metastasis. The nervous system governs functional activities of many organs, and, as tumors are not independent organs within an organism, this system is integrally involved in tumor growth and progression.

Clinical Outcomes in pT4 Tongue Carcinoma are Worse than in pT3 Disease: How Extrinsic Muscle Invasion Should be Considered? Ann Surg Oncol 2017; 24:2570-2579. [PMID: 28577181 DOI: 10.1245/s10434-017-5906-3] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2017] [Indexed: 11/18/2022]
Abstract
BACKGROUND The identification of extrinsic tongue muscle invasion in oral cavity cancer remains challenging. Notably, the most recent American Joint Committee on Cancer (AJCC 2017, 8th edition) staging manual indicates that extrinsic muscle invasion does not lead to the diagnosis of a T4 tumor. Because this approach carries the risk of tumor downstaging, we compared the clinical outcomes of patients with oral tongue squamous cell carcinoma (SCC) staged as pT3 vs. pT4 according to the AJCC 2010, 7th edition criteria. METHODS We retrospectively examined the records of consecutive patients with pT3 (n = 135) and pT4 (n = 68) tongue SCC who underwent radical surgery. Of the 68 pT4 tongue SCC, 63 (93%) had extrinsic muscle involvement alone. The 5-year locoregional control (LRC), distant metastasis (DM), and disease-free survival (DFS) rates served as outcome measures. RESULTS Compared with pT3 tongue SCC, pT4 patients presented significantly more frequently with pN2 disease, extranodal extension, poor tumor differentiation, tumor depth >15 and >20 mm, margin status ≤4 mm, perineural invasion, vascular invasion, and were more frequently treated with surgery plus concurrent chemoradiotherapy. Less favorable 5-year outcomes were observed in patients with pT4 than pT3 tumors (LRC 50 vs. 75%, p < 0.001; DM 27 vs. 14%, p = 0.013; DFS 43 vs. 69%, respectively, p < 0.001). We identified pT4 disease (vs. pT3) as an independent adverse prognostic factor for LRC and DFS. CONCLUSIONS We suggest classifying patients with tongue SCC and extrinsic muscle invasion as having pT4 disease.

Abstract
OBJECTIVE Human papillomavirus-associated (HPV) oropharyngeal cancer is a unique clinical entity whose incidence is increasing. It is controversial whether traditional pathologic markers of aggressive head and neck cancer also apply in surgically treated HPV-associated disease. STUDY DESIGN Retrospective study, systematic review, and meta-analysis Data Sources: PubMed and Cochrane review. REVIEW METHODS PubMed and Cochrane review were searched for published articles on surgically treated HPV-associated oropharyngeal cancer. Eligible studies were included in a meta-analysis of survival using several clinicopathologic markers as predictors. Surgically treated HPV-positive oropharyngeal cancer patients at our institution were studied retrospectively and added to the meta-analysis. RESULTS Eight published reports, plus our retrospective series, were included in the meta-analysis. This showed significant impact on event-free survival for T stage, nodal number, perineural invasion, and lymphovascular invasion (all P < .05) but not for N stage extracapsular extension ( P = ns). CONCLUSIONS While many traditional clinico-pathologic markers of aggressive disease in head and neck cancer also impact survival in surgically treated HPV-associated oropharyngeal cancer, extracapsular extension may be less important.

Abstract
BACKGROUND The purpose of this study was to identify clinicopathological and immunohistochemical factors predicting delayed lymph node metastases and survival in early oral squamous cell carcinoma (OSCC). METHODS The study included 85 consecutive patients with clinically T1 to T2N0 OSCC who were primarily surgically treated between 2000 and 2004. RESULTS There were 68 men and 17 women (median age, 61 years; range, 34-82 years). Of all the patients, 25 (29.4%) developed delayed lymph node metastases within 3 to 42 months after treatment of the primary tumor. Multivariate logistic regression analysis identified poorly differentiated tumors, low laminin, and high fibronectin expression as prognosticators of delayed lymph node metastases. Cox's proportional hazards regression analysis demonstrated that moderately differentiated tumors and delayed lymph node metastases had predictive value regarding survival. CONCLUSION Large prospective investigations with reproducibility and the clinical translatability of immunohistochemical methods are needed in order to provide new and effective therapeutic strategies in the future. © 2016 Wiley Periodicals, Inc.

Abstract
Introduction Oral carcinoma can cause significant defects that would necessitate a challenging reconstructive surgery. These techniques include biological or synthetic dressings, grafts, regional flaps, and free-vascularized flaps. Among these, the dural graft has demonstrated promising results in repairing the skull-base defects. Our aim is to report a new, innovative technique for partial glossectomy and floor of mouth defect repair using a biological dural graft dressing when primary repair was not feasible and the patient did not consent to dermal graft or flap interventions. Presentation of case This article reports the outcomes from a novel intervention of partial glossectomy repair using a biological dural dressing derived from bovine type-I collagen in a 57-year-old female patient with recurrent T1N1M0 squamous cell carcinoma of the left-sided tongue during the 12 month period of follow-up. Discussion The best option for large tongue defects is a free flap, while for a moderate defect is a regional oral flap. The biological graft, as an acellular dermal graft has been well known to facilitate secondary healing in the tongue as an alternative to the split-thickness skin graft. In the current study, the dural dressing in tongue reconstruction was likewise shown to be an effective biological dressing; hence, the collagen membrane is biologically acceptable to the oral mucosa and an excellent wound graft material. However, it is absolutely contraindicated in bovine hypersensitive patients. Conclusion The biological dural graft dressing appears to be an effective method for tongue reconstruction, as it promotes adequate wound healing and it preserves function.
