Abstract
Oral carcinoma is a common disease that poses challenges in treatment management, especially for advanced cases. Adjuvant therapies, such as radiation and chemoradiation therapy, are typically used for advanced oral cancer patients. However, there is uncertainty regarding the use of adjuvant therapy for early-stage patients with certain soft histological parameters. The UICC manual of clinical oncology suggests that adjuvant therapy for such parameters is desirable but not essential. These parameters include perineural invasion, lymphovascular invasion, single nodal positivity, and patterns of invasion, which complicate the decision-making process for including adjuvant therapy. This review aims to provide evidence-based literature for effectively managing this patient group and developing treatment protocols based on current evidence.

Li X. The Predictive Value of BUB1 in the Prognosis of Oral Squamous Cell Carcinoma. Int Dent J 2024:S0020-6539(24)00201-6. [PMID: 39147662 DOI: 10.1016/j.identj.2024.07.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2024] [Revised: 07/09/2024] [Accepted: 07/12/2024] [Indexed: 08/17/2024] Open
Abstract
BACKGROUND Oral squamous cell carcinoma (OSCC) is the most common type of malignant tumour in the oral cavity, and it is known for its poor prognosis. Budding uninhibited by benzimidazoles 1 (BUB1) may be related to cancer prognosis; however, the specific relationship between BUB1 and OSCC prognosis remains largely unexplored. METHODS The mRNA levels of BUB1 were analysed using data from the TCGA_OSCC and GSE23558 cohorts. OSCC samples from the TCGA_OSCC dataset were divided into low- and high-BUB1 expression groups based on the median BUB1 level. Furthermore, results of survival analysis, tumour mutation burden (TMB), gene set enrichment analysis (GSEA) pathways, and drug-sensitivity analysis were compared between the 2 groups. RESULTS Based on the data from the TCGA_OSCC and GSE23558 cohorts, BUB1 mRNA levels were significantly upregulated in OSCC tissues compared to healthy controls. Moreover, high expression of BUB1 may serve as an independent indicator of poor prognosis in OSCC. Additionally, patients with high BUB1 expression also exhibited increased levels of immune checkpoints and TMB, suggesting that patients with high BUB1 expression may benefit from immunotherapy. Mechanistically, transcription factors ZFP64, TCF3, and ZNF281 were found to potentially bind to the promoter region of BUB1, thereby regulating its gene expression. Furthermore, GSEA results showed that BUB1 expression was closely related to cell cycle and tumour-related pathways in OSCC. Drug-sensitivity analysis showed that patients with high BUB1 expression may be more sensitive to gemcitabine, paclitaxel, or imatinib. CONCLUSIONS Collectively, results demonstrated that high BUB1 levels may be related to a poor prognosis of OSCC, highlighting its potential as a novel prognostic biomarker for OSCC.

Laryngoscope Investig Otolaryngol 2024; 9:e1260. [PMID: 38751691 PMCID: PMC11094775 DOI: 10.1002/lio2.1260] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2023] [Revised: 02/13/2024] [Accepted: 04/28/2024] [Indexed: 05/18/2024] Open
Abstract
Objectives The aim of this meta-analysis is to evaluate the potential benefits of postoperative radiotherapy (PORT) in patients with pN1 oral cavity squamous cell carcinoma. Methods A literature search through major databases was conducted until January 2023. The adjusted hazard ratio (aHR) or risk ratio (RR) with 95% confidence intervals (CIs) of different survival outcomes were extracted and pooled. Results Ten studies published between 2005 and 2022, with a pooled patient population of 2888, were included in this meta-analysis. Due to differences in study design and reported outcomes, the studies were categorized into distinct groups. In pN1 patients without extranodal extension (ENE), PORT was associated with a significant improvement in overall survival (OS) (aHR 0.76, 95% CI: 0.61-0.94). In pN1 patients without ENE and positive margins, PORT improved OS (aHR 0.71, 95% CI: 0.56-0.89) and was associated with a lower regional recurrence rate (RR 0.35, 95% CI: 0.15-0.83). However, in pN1 patients without ENE, positive margins, perineural invasion, and lymphovascular invasion, there were no significant differences observed between the PORT and observation groups in either 5-year OS (RR 0.48, 95% CI: 0.07-3.41) or 5-year disease-free survival (RR 0.37, 95% CI: 0.07-2.06). Conclusions The current study demonstrated that PORT has the potential to improve OS in pN1 disease. However, the decision of whether to administer PORT still hinges on diverse clinical scenarios, and additional research is necessary to furnish a more conclusive resolution. Level of Evidence 2.

Abstract
PURPOSE The study aimed to retrospectively identify the prognostic factors of surgically treated primary tongue squamous cell carcinoma (TSCC) cases and assess the benefits of surgical neck lymph node dissection (LND) in early-stage cancer. METHODS Patients with primary TSCC with pT1-2N0-1M0 stage without distant metastasis who were treated with surgery during 2014-2016 at Xiangya Hospital, Central South University were included. Univariate and multivariate Cox models were constructed to explore prognostic factors of overall survival (OS), disease-free survival (DFS), and local recurrence-free survival (LRFS). Sub-group analysis was used to assess the effect of adjuvant therapy and the prognostic value of LND for the early-stage patients. RESULTS In total, 440 patients met the inclusion criteria. During the follow-up period, the 5-year OS, DFS, were 84.4% and 70.0%, respectively. Univariate analysis showed that TNM stage, lymphovascular invasion (LVI), and/or perineural invasion (PNI), pathological differentiation, etc. were significant predictors of OS and DFS. Multivariate analysis showed that TNM stage and the degree of pathological differentiation were independent prognostic factors for all outcomes. Besides, the number of cervical LND could independently predict both DFS and LRFS while LVI/PNI were associated with DFS. And high-quality neck LND (≥30) significantly improved DFS and LRFS for patients of pT1cN0M0 or stage I as compared to those without LND. CONCLUSIONS TNM stage and pathological differentiation were crucial prognostic factors for postoperative patients with TSCC. Notably, high-quality cervical LND was beneficial for the improvement of DFS and LRFS for patients of pT1cN0M0 or stage I.

Abstract
OBJECTIVES To investigate thresholds for lymph node yield (LNY), lymph node density (LND), and pN in patients with oral squamous cell carcinoma in relation to previous findings in the literature. STUDY DESIGN Retrospective register-based study. SETTING Copenhagen Oral Cavity Squamous Cell Carcinoma database. METHODS Appropriate thresholds for LNY, LND, and pN were determined by areas under the curve and subsequently subjected to multivariate analysis. Five-year overall survival and 3-year recurrence-free survival were determined by Kaplan-Meier survival curves. RESULTS In total, 413 patients diagnosed with oral squamous cell carcinoma were included. In the pN0 cohort, no superior/prognostic LNY cutoff values were detected. In the pN+ cohort, areas under the curve determined thresholds of LNY, LND, and pN to be 21 nodes, 5%, and 3 metastases, respectively. The 5-year overall survival was 52% for patients with LNY ≥21 vs 38% for patients with LNY <21 (hazard ratio [HR], 1.49; 95% CI, 1.05-2.11; P < .05), 60% for patients with LND ≤5% vs 38% for patients with LND >6% (HR, 1.63; 95% CI, 1.03-2.57; P < .05), and 43% for patients with pN <3 vs 26% for patients with pN ≥3 (HR, 1.40; 95% CI, 1.04-2.15; P < .05). CONCLUSIONS Increased nodal yield, decreased LND, and decreasing number of pN were associated with significantly improved survival outcomes. LNY might serve as a prognosticator of survival as well as a surgical quality indicator. LND may have implications as a tool in cancer staging and treatment planning.

Abstract
OBJECTIVE The study aimed to determine the optimal count of examined lymph nodes (ELN) for accurate assessment of lymph node status and favorable long-term survival in patients with oral tongue squamous cell carcinoma (OTSCC) who received radical resection. METHODS Patients with OTSCC who received radical resection between 2004 and 2015 were enrolled from the Surveillance, Epidemiology, and End Results database (SEER) and were randomly divided into two cohorts. The association of ELN count with nodal migration and overall survival (OS) was analyzed using a multivariate regression model with the adjustment of relevant factors. Locally weighted scatterplot smoothing (LOWESS) and 'strucchange' package were adopted to identify the optimal cut points using R. RESULTS A total of 2077 patients were included in this study. The optimal cut points of ELN count for accurate nodal staging and favorable OS were 19 and 15, respectively. The probability of detecting positive lymph nodes (PLN) significantly increased in patients with ELN count ≥ 19 in comparison to those with ELN count < 19 (training set, P < 0.001; validation set, P = 0.012). A better postoperative prognosis was observed in patients with ELN count ≥ 15 than those with fewer ELN (training set, P = 0.001, OR: 0.765; validation set, P = 0.016, OR: 0.678). CONCLUSION The optimal cut point of ELN count to ensure the accuracy of nodal staging and to achieve a favorable postoperative prognosis were 19 and 15, respectively. The ELN count beyond the cutoff values might improve the accuracy of cancer staging and OS.

Abstract
BACKGROUND The presence of single-node metastasis (Ns) sometimes could be encountered in patients with oral squamous cell carcinoma (OSCC). The survival outcome for different Ns should be worthy of discussion. METHODS Patients diagnosed with OSCC at the National Taiwan University Hospital between January 2007 and December 2018 were reviewed. All patients with Ns were classified into two groups: with and without extranodal extension (ENE). RESULTS We analyzed 311 OSCC patients with Ns: 77 (24.76%) with and 234 (75.24%) without ENE. Lymph node (LN) >3 cm was the only significant factor associated with ENE (odds ratio 17.21, p < 0.001). The 5-year, disease-free survival of N1/N2A and N3B patients was 60.5% and 49.4%, respectively (p = 0.04), and the 5-year overall survival was 63.1% and 33.6%, respectively (p = 0.0001). Four fifths of Ns patients with LN >3 cm were upgraded to N3B category as ENE+. Postoperative radiotherapy (PORT) could provide significant benefit in regional control for Ns patients with (p = 0.03) and without (p = 0.0004) other adverse features. After multivariant Cox analysis, ENE+ was a modest and significant risk factor for disease-free (p = 0.08) and overall survival (p = 0.001). By contrast, the LN>3cm and N2A category were not significant risk factors for disease-free and overall survival. CONCLUSIONS For OSCC patients with Ns, the survival outcome between N3B category and N1/N2A category was significantly different. After ENE+ upgrades (>80%), there were fewer N2A patients, and these patients became more comparable to N1 patients. PORT could significantly improve regional control for Ns patients.

Abstract
PURPOSE Lymph node density (LND) has been reported to be a significant predictor of survival in oral squamous cell carcinoma (OSCC). The aim of this study was to analyze LND as a prognostic factor in OSCC and create a predictive model that determines the probability of death in these patients. METHODS A retrospective cohort study was carried out with a cohort of patients who underwent cervical dissection and primary resection of OSCC between 1980 and 2020. The primary predictor variable in this study was LND, which is defined as the number of positive lymph nodes divided by the total number of lymph nodes removed. The cutoff values for prediction of disease-specific survival (DSS) were calculated by receiver operating characteristic curve analysis, which determined the best cutoff value was 0.07. Patients were divided into binary subgroups (low and high risk) using the best cutoff value of LND. The outcome variable was DSS, defined as the duration from the date of diagnosis to death due to OSCC and not due to other causes or secondary tumors. Other variables were type of neck dissection, postsurgical treatment, surgical margin, pathological T category stage, pathological N category (pN) stage, extranodal extension, perineural invasion, bone invasion, and presence of recurrence. A predictive model (score) was generated by selecting variables using a log-rank test and by using the Cox proportional-hazards regression (multivariate analysis). RESULTS The sample consisted of 368 patients, 252 (68.5%) male and 116 (31.5%) female patients, with a mean age of 60.3 years. According to the LND cutoff value, there were 289 patients with a low LND (≤0.07) and 79 with a high LND (>0.07). The univariate analysis showed LND as a significant predictor of DSS at 5 years (67.1% in LND ≤ 0.07 vs 32.9% in LND > 0.07; P < .001). The Cox multivariate analysis identified LND (hazard ratio [HR] = 27.2; 95% confidence interval [CI], 3.18-231; P = .002), recurrence (HR = 4.45; 95% CI, 2.3-8.4; P < .001), and type of treatment (HR = 0.52; 95% CI, 0.34-0.81; P < .001) as independent predictive factors for DSS. In the predictive model, the presence of recurrence was the most important factor with 8 points, whereas LND >0.07 contributed only 1 point; however, the 2 categories resulting from this limit were statistically significant. CONCLUSIONS Our study demonstrates that LND is an additional prognostic factor in patients with a pN+ disease. In addition, our predictive model could be useful in the therapeutic algorithm of OSCC patients, as it can predict the probability of death in these patients.

Abstract
BACKGROUND To analyze the influence of the lymph node ratio (LNR) in survival of patients with OSCC METHODS: Clinicopathologic data from patients with OSCC who were treated with curative surgery and neck dissection (ND) with or without adjuvant therapies from 1991 to 2015 was retrospectively assessed. The impact of LNR and other variables on overall survival (OS) and disease-free survival (DFS) was analyzed in univariate and multivariate analyses. RESULTS One hundred nineteen patients were included. In the univariate analysis the LNR had a significant impact on OS (p = 0.01) and DFS (p = 0.01). In the multivariate analysis, the LNR was the only significantly independent factor influencing in the OS (p = 0.03). The adjuvant therapies did not influence on the OS (p = 0.42) and DFS (p = 0.10). CONCLUSIONS The LNR is an independent prognostic factor in patients with OSCC. The LNR alone is not recommended to indicate the performance of adjuvant therapies.

Relationship between lymph nodes examined and survival benefits with postoperative radiotherapy in oral cavity squamous cell carcinoma patients with stage T1-2N1M0. Front Surg 2022; 9:928455. [PMID: 36248371 PMCID: PMC9554262 DOI: 10.3389/fsurg.2022.928455] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2022] [Accepted: 09/05/2022] [Indexed: 11/17/2022] Open
Abstract
Background This study aims to explore the relationship between the lymph nodes examined and survival benefits of postoperative radiotherapy in oral cavity squamous cell carcinoma patients with stage T1-2N1M0. Methods This study retrieved patients who underwent dissection of the primary site and neck lymph nodes for pT1-2N1M0 oral cavity squamous cell carcinoma without adverse nodal features from the Surveillance, Epidemiology, and End Results database from 2004 to 2015. Propensity score matching analysis was conducted, and the best cutoff value of the lymph nodes examined was determined by X-tile. Cancer-specific survival was the primary outcome. Univariable and multivariable analyses were performed to assess the relation between postoperative radiotherapy and cancer-specific survival, adjusting for other prognostic factors. Results A total of 469 patients were finally enrolled according to our exclusion criteria, and then 119 pairs of patients were matched by propensity score matching analysis. The best cutoff value of the lymph nodes examined was determined by X-tile, stratifying patients into lymph nodes examined ≤16 group and lymph nodes examined >16 group. For the whole matched cohort, the choice of postoperative radiotherapy had no correlation with other factors (all p’s > 0.05), and postoperative radiotherapy made no contribution to a better survival outcome for patients (p = 0.289). After stratified by the lymph nodes examined, in the lymph nodes examined ≤16 group, significantly improved CSS was found for those who undertook postoperative radiotherapy compared to those who just received surgery (unadjusted hazard ratio, 0.541; 95% confidence interval, 0.333–0.878; p = 0.013). Conclusions Our study revealed that pT1-2N1M0 oral cavity squamous cell carcinoma patients were more likely to benefit from postoperative radiotherapy when unsatisfactory neck dissection was conducted, indicating that the number of lymph nodes examined might be a factor when clinicians do therapeutic planning for early-stage oral cavity squamous cell carcinoma patients.

Gartagani Z, Doumas S, Kyriakopoulou A, Economopoulou P, Psaltopoulou T, Kotsantis I, Sergentanis TN, Psyrri A. Lymph Node Ratio as a Prognostic Factor in Neck Dissection in Oral Cancer Patients: A Systematic Review and Meta-Analysis. Cancers (Basel) 2022; 14:cancers14184456. [PMID: 36139617 PMCID: PMC9497248 DOI: 10.3390/cancers14184456] [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: 08/27/2022] [Revised: 09/08/2022] [Accepted: 09/12/2022] [Indexed: 11/16/2022] Open
Abstract
Simple Summary Lymph node ratio (LNR) is a well-studied prognostic factor in colorectal and breast cancer, and it has been recently evaluated as a clinically relevant biomarker in oral squamous cell carcinoma. LNR represents the ratio of positive lymph nodes extracted in a neck dissection to the total number of nodes harvested (lymph node yield, LNY). Many single-center cohort studies and a few multicenter have assessed the significance of LNR as a prognostic factor in oral cancer. In this systematic review and meta-analysis of 32 studies and 20,994 oral cancer patients, we demonstrate that LNR is an independent prognostic indicator in patients with oral squamous cell carcinoma. Abstract Many studies have evaluated the clinical implications of lymph node ratio (LNR) as a prognostic factor in patients with oral squamous cell carcinoma (OSCC). The main purpose of this systematic review and meta-analysis was to address LNR as a prognosticator in patients with OSCC. A systematic search was conducted in the following databases: PubMed, EMBASE, Google Scholar, OpenGrey, Cochrane library, and ClinicalTrials.gov, and studies between 2009 and 2020 were sought. The pooled relative risk was calculated along with 95% confidence intervals for the following endpoints: overall survival (OS), disease-free survival (DFS), disease-specific survival (DSS), distant metastasis-free survival (DMFS), locoregional disease-free survival (LRDFS), local recurrence-free survival (LRFS), and recurrence-free survival (RFS) according to the random-effects model (Der Simonian–Laird approach). Subgroup and meta-regression analyses were performed as well. Finally, 32 cohort studies were eligible, which included 20,994 patients with OSCC. Patients were subdivided into two categories, group YES (studies that included in their analysis only patients with positive lymph nodes) and group NO (studies that did not exclude LNR = 0 patients). In the group YES, patients with high LNR had shorter OS (RR = 1.68, 95% CI: 1.47–1.91), DFS (RR = 1.68, 95% CI: 1.42–1.99), DSS (RR = 1.94, 95% CI: 1.56–2.42), DMFS (RR = 1.83, 95% CI: 1.13–2.96), LRDFS (RR = 1.55, 95% CI: 1.10–2.20), and LRFS (RR = 1.73, 95% CI: 1.41–2.13) compared to patients with low LNR. In the group NO, patients with high LNR in comparison had shorter OS (RR = 2.38, 95% CI: 1.99–2.85), DFS (RR = 2.04, 95% CI: 1.48–2.81), and DSS (RR = 2.90, 95% CI: 2.35–3.57) compared to patients with low LNR. Based on those findings, LNR might be an independent prognostic factor for OS in patients with OSCC and could be incorporated into future classification systems for better risk stratification.

Adding Concomitant Chemotherapy to Postoperative Radiotherapy in Oral Cavity Carcinoma with Minor Risk Factors: Systematic Review of the Literature and Meta-Analysis. Cancers (Basel) 2022; 14:cancers14153704. [PMID: 35954368 PMCID: PMC9367295 DOI: 10.3390/cancers14153704] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2022] [Revised: 07/15/2022] [Accepted: 07/18/2022] [Indexed: 11/17/2022] Open
Abstract
When presenting with major pathological risk factors, adjuvant radio-chemotherapy for oral cavity cancers (OCC) is recommended, but the addition of chemotherapy to radiotherapy (POCRT) when only minor pathological risk factors are present is controversial. A systematic review following the PICO-PRISMA methodology (PROSPERO registration ID: CRD42021267498) was conducted using the PubMed, Embase, and Cochrane libraries. Studies assessing outcomes of POCRT in patients with solely minor risk factors (perineural invasion or lymph vascular invasion; pN1 single; DOI ≥ 5 mm; close margin < 2−5 mm; node-positive level IV or V; pT3 or pT4; multiple lymph nodes without ENE) were evaluated. A meta-analysis technique with a single-arm study was performed. Radiotherapy was combined with chemotherapy in all studies. One study only included patients treated with POCRT. In the other 12 studies, patients were treated with only PORT (12,883 patients) and with POCRT (10,663 patients). Among the patients treated with POCRT, the pooled 3 year OS rate was 72.9% (95%CI: 65.5−79.2%); the pooled 3 year DFS was 70.9% (95%CI: 48.8−86.2%); and the pooled LRFS was 69.8% (95%CI: 46.1−86.1%). Results are in favor of POCRT in terms of OS but not significant for DFS and LRFS, probably due to the heterogeneity of the included studies and a combination of different prognostic factors.

Abstract
Objectives Different parameters have been identified in patients with oral squamous cell carcinomas (OSCC) that have a serious impact on survival, including residual tumour and extracapsular spread. Moreover, other factors, including the lymph node ratio (LNR) and lymph node yield (LNY), have been suggested as prognostic markers. Material and methods This retrospective study included patients diagnosed with OSCC and cervical lymph node metastases during the years 2010–2020. Patients’ records were evaluated regarding lymph node status, final therapy regime, tumour recurrence, time to death, tumour association with death, disease-free survival (DSF), and overall survival (OS). Results In 242 patients with a mean age of 63.57 ± 11.24 years, treated either by selective neck dissection (SND; n = 70) or by modified radical neck dissection (MRND; n = 172), 5772 lymph nodes were detected. The LNR and LNY were identified as independent risk factors in OS and DFS. The optimal cut-off point for the LNY was ≥ 17 lymph nodes in the SND and ≥ 27 lymph nodes in the MRND group. The metastatic lymph node clearance (MLNC) was established as a score to relate the LNR and LNY to the extent of lymph node removal. Survival analysis showed statistically significant differences among score levels. Conclusions As information about the extent of nodal dissection is excluded from LNR and LNY, we propose the use of a new scoring system comprising individual cut-off values for LNY and LNR with regard to the extent of neck dissection. Clinical Relevance MLNC might help to identify high-risk OSCC patients with metastatic lymph nodes.

Abstract
BackgroundTo assess the prognostic significance of different nodal parameters [i.e., number of pathologically positive nodes, log odds of positive lymph nodes, lymph node ratio (LNR), and extra-nodal extension (ENE)] in Taiwanese patients with oral cavity squamous cell carcinoma (OCSCC), and to devise an optimized pN classification system for predicting survival in OCSCC.MethodsA total of 4287 Taiwanese patients with first primary OCSCC and nodal metastases were enrolled. Cox proportional hazards regression analysis with the spline method was applied to identify the optimal cut-off values for LNR, log odds of positive lymph nodes, and number of pathologically positive nodes.ResultsOn multivariable analysis, we identified a LNR ≥0.078/0.079, the presence of at least three pathologically positive nodes, and ENE as independent prognosticators for 5-year disease-specific survival (DSS) and overall survival (OS) rates. We therefore devised a four-point prognostic scoring system according to the presence or absence of each variable. The 5-year DSS and OS rates of patients with scores of 0−3 were 70%/62%/50%/36% (p <0.0001) and 61%/52%/40%25%, respectively (p <0.0001). On analyzing the AJCC 2017 pN classification, patients with pN3a displayed better survival rates than those with pN2 disease. The 5-year DSS and OS rates of patients with pN1/pN2/pN3a/pN3b disease were 72%/60%/67%/43% (p <0.0001) and 63%/51%/67%/33%, respectively (p <0.0001).ConclusionsThree nodal parameters (i.e., a LNR ≥0.078/0.079, the presence of at least three pathologically positive nodes, and ENE) assessed in combination provided a better prognostic stratification than the traditional AJCC pN classification.

Abstract
In this study, we aimed to investigate the prognostic value of the number of pathologically positive nodes (pN+) in p16-negative oropharyngeal (OPSCC) and hypopharyngeal (HPSCC) squamous cell carcinoma cases with pN3b status after surgery. We reviewed the clinical and pathological features of 120 newly diagnosed p16-negative OPSCC and HPSCC patients with pN3b status after radical surgery. The primary endpoints were the 5-year overall survival (OS), cancer-specific survival (CSS), and their prognostic factors. We used the Cox proportional hazards model for survival analysis. We generated predictive nomograms that incorporated the clinicopathological factors of OS and CSS. The 5-year OS and CSS rates were 44.1% and 59.1%, respectively. The optimal number of pN+ to predict the 5-year OS and CSS was pN+ = 3. In the Cox model, we observed that pN+ ≥ 3 was a significantly negative predictor of OS (HR: 1.9, 95% CI: 1.1–3.2, p = 0.021) and CSS (HR: 2.3; 95% CI: 1.2–4.6; p = 0.015). After adding the pN+ variable, the c-index of the predictive nomogram incorporating assorted clinicopathological factors increased from 0.66 to 0.689 for OS and from 0.713 to 0.75 for CSS. The results highlight the prognostic value of the pN+ number in p16-negative OPSCC and HPSCC patients with pN3b status.

Abstract
INTRODUCTION the variable lymph node ratio has recently been studied as a possible influencer in the survival of patients diagnosed with head and neck cancer. OBJECTIVE to analyze the correlation between lymph node density and survival of recurred disease patients previously submitted to cervical dissection surgery due to head and neck squamous cell carcinoma. METHOD we retrospectively analyzed 71 medical records of patients treated at the Head and Neck Surgery Service of the Pontifícia Universidade Católica de Campinas who had undergone cervical dissection surgery and presented tumor recurrence between 2006 and 2019. Patient and tumor data such as age, gender, skin color, smoking, alcohol consumption, location of the primary tumor, anatomopathological characteristics and lymph node status were correlated with the survival time. RESULTS we found a predominance of males and the mean age was 59.5 years. The most frequent primary site was the oral cavity followed by the larynx and oropharynx. The mortality rate was 53.52% and the mean lymph node ratio 0.28. We found influence on survival with statistical significance for the parameters: lymph node ratio, number of dissected and affected lymph nodes, T and N staging, type of treatment proposed (palliative or surgical), presence of compromited margins in the primary tumor and lymph node extravasation. CONCLUSION the calculation of lymph node density in patients with recurred disease after cervical dissection surgery by head and neck squamous cell carcinoma should be taken into account during therapeutic planning and prognostic evaluation due to its direct influence on the survival.

Abstract
Background Lymph node ratio (LNR) has been reported to reliably predict cancer-specific survival (CSS) in parotid gland cancer (PGC). Our study was designed to validate the significance of LNR in patients with PGC. Methods Patients diagnosed with stage I–IV PGC were enrolled from Surveillance Epidemiology and End Results database (SEER, N = 3529), which is the training group, and Sun Yat-sen University Cancer Center database (SYSUCC, N = 99), the validation group. We used X-tile software to choose the optimal cutoff value of LNR; then, univariable and multivariable analyses were performed, assessing the association between LNR and CSS. Results The optimal cutoff value of LNR was 0.32 by X-tile based on 3529 patients from SEER. Cox proportional hazard regression analysis revealed better CSS for patients with LNR ≤ 0.32 (adjusted hazard ratio [HR] 1.612, 95% confidence interval [95% CI] 1.286–2.019; p < 0.001) compared with patients with LNR > 0.32 in SEER. In the SYSUCC cohort, patients with LNR ≤ 0.32 also had better CSS over patients with LNR > 0.32 (p < 0.001). In N2 and N3 stage groups, patients with LNR ≤ 0.32 had superior CSS outcomes over those with the LNR > 0.32 group, but this benefit was absent in the N1 stage group. Conclusions In conclusion, the lymph node ratio turned out to be an independent prognostic factor for cancer-specific survival of PGC in this study. This valuable information could help clinicians to evaluate the prognosis of PGC and suggest that adequate lymph node dissection is necessary.

J Otolaryngol Head Neck Surg 2022; 51:18. [PMID: 35484627 PMCID: PMC9052608 DOI: 10.1186/s40463-022-00573-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2021] [Accepted: 03/31/2022] [Indexed: 11/25/2022] Open
Abstract
Background Oral cancer with pT1-3N1 without extracapsular extension of the lymph node is classified as stage III according to the eighth edition of the AJCC staging system. Outcomes of a subgroup of patients classified as having stage III oral cancer with single nodal metastasis are observed to be various clinically. Therefore, such clinical outcomes for subgroup analyses in this cohort are necessary.
Methods Patients with pT1-3N1 (based on the eighth edition of the AJCC staging system) oral cancer who underwent surgery between 2007 and 2016 were enrolled retrospectively for survival analyses. Results A total of 105 patients—including 28 patients with pT1N1 disease and 77 patients with pT2-3N1 disease—participated in the study. Pathological T classification was the only statistically significant prognosticator according to univariate analysis. The patients with pT1N1 disease showed better 5-year overall survival (OS), disease specific survival (DSS), and disease free survival (DFS) than those with pT2-3N1 disease (pT1N1 vs pT2-3N1, OS: 96.4% vs 72.2%, p = 0.004; DSS: 96.4% vs 77.3%, p = 0.021; DFS: 84.6% vs 62.3%, p = 0.023). Besides, there was no potential clinicopathological confounder which is significant associated with different pathological T classifications in this unique cohort. Conclusions Patients in the pT1N1 subgroup have significantly favorable prognosis than those with pT2-3N1 disease. Down-staging and reclassifying pT1N1 subgroup patients with oral cancer may be considered in tumor staging. Graphical Abstract ![]()

Lymph node ratio-based nomogram for prognosis evaluation and treatment optimization of non-metastatic oral cavity squamous cell carcinoma. Transl Oncol 2022; 20:101401. [PMID: 35339030 PMCID: PMC8957048 DOI: 10.1016/j.tranon.2022.101401] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2021] [Revised: 02/19/2022] [Accepted: 03/15/2022] [Indexed: 12/09/2022] Open
Abstract
LNR is an independent prognostic factor over N stage in OCSCC. LNR-based nomogram surpasses AJCC TNM staging in predicting outcome of OCSCC. LNR-based nomogram is valid in guiding post-operative radiotherapy in OCSCC.
Background Lymph node ratio (LNR) has been increasingly reported as a prognostic factor in oral cavity squamous cell carcinoma (OCSCC). This study aimed to develop and validate a prognostic nomogram integrating LNR and to further assess its role in guiding adjuvant therapy for OCSCC. Methods A total of 8703 OCSCC patients treated primarily with surgery in the Surveillance, Epidemiology and End Results (SEER) database were retrieved and randomly divided into training and validation cohorts. The nomogram was created based on the factors identified by Cox model. The value of PORT and chemotherapy was respectively evaluated in each prognostic group according to nomogram-deduced individualized score. Results The final nomogram included tumor site, grade, T stage, number of positive lymph nodes and LNR. Calibration plots demonstrated a good match between predicted and observed rates of overall survival (OS). The concordance indexes for training and validation cohorts were 0.720 (95% confidence interval (CI): 0.708, 0.732) and 0.711 (95% CI: 0.687, 0.735), both significantly higher than did TNM stage (p< 0.001). According to individualized nomogram score, patients were stratified into three subgroups with significantly distinct outcome. PORT presented survival benefit among medium- and high-risk groups whereas a near-detrimental effect in low-risk group. Chemotherapy was found to be beneficial only in high-risk group. Conclusion This LNR-incorporated nomogram surpassed the conventional TNM stage in predicting prognosis of patients with non-metastatic OCSCC and identified sub-settings that could gain survival benefit from adjuvant thearpy.

Abstract
RESUMO Introdução: recentemente tem-se estudado a variável densidade linfonodal como possível influenciador na sobrevida de pacientes com diagnóstico de câncer de cabeça e pescoço. Objetivo: analisar a relação entre a densidade linfonodal e a sobrevida de pacientes recidivados previamente submetidos a cirurgia de esvaziamento cervical por carcinoma espinocelular de cabeça e pescoço. Método: foram analisados retrospectivamente 71 prontuários pacientes atendidos no Serviço de Cirurgia de Cabeça e Pescoço da Pontifícia Universidade Católica de Campinas que tinham sido submetidos a cirurgia de esvaziamento cervical e apresentaram recidiva tumoral entre os anos de 2006 e 2019. Dados relativos ao paciente e ao tumor tais como: idade, sexo, cor da pele, tabagismo, etilismo, localização do tumor primário, características anatomopatológicas e status linfonodal foram correlacionados ao tempo de sobrevida dos indivíduos. Resultados: encontramos predominância do sexo masculino e a média de idade foi de 59,5 anos. O sítio primário mais frequente foi a cavidade oral seguido da laringe e orofaringe. A taxa de mortalidade foi de 53,52% e a densidade linfonodal média 0,28. Encontramos influência na sobrevida com significância estatística para os parâmetros: densidade linfonodal, número de linfonodos dissecados e acometidos, estadiamento T e N, tipo de tratamento proposto (paliativo ou cirúrgico), presença de margens comprometidas no tumor primário e extravasamento linfonodal. Conclusão: o cálculo da densidade linfonodal em pacientes recidivados após cirurgia de esvaziamento cervical por carcinoma espinocelular de cabeça e pescoço deve ser levado em consideração durante o planejamento terapêutico e na avaliação prognóstica devido à sua direta influencia na sobrevida dos indivíduos.

Abstract
Background: Head and neck cancer patients often suffer from dysphagia after surgery and
radiotherapy. A singing-enhanced swallowing protocol was established to
improve their swallowing function. This study aimed to evaluate the
beneficial effects of therapeutic singing on dysphagia in head and neck
cancer (HNC) patients. Methods: Patients who participated in this study were allocated to the intervention
group (15 patients) and the control group (13 patients). Patients assigned
to the intervention group received therapeutic singing 3 times per week for
4 weeks. Each group was divided into 2 subgroups, including the oral cavity
cancer group and the pharyngeal cancer group. The patients’ vocal functions
were evaluated in maximum phonation time, pitch, intensity, jitter, shimmer,
harmonics to noise ratio, and laryngeal diadochokinesis (L-DDK). To evaluate
swallowing function, videofluoroscopic swallowing study was done, and the
results were analyzed by videofluoroscopic dysphagia scale (VDS) and dynamic
imaging grade of swallowing toxicity (DIGEST). Results: Among the voice parameters, L-DDK of the intervention group significantly
increased compared to that of the control group. Swallowing functions of the
intervention group were significantly improved in VDS and DIGEST after the
intervention. Detailed items of VDS and DIGEST showed improvements
especially in the pharyngeal phase score of VDS, such as laryngeal
elevation, pharyngeal transit time, and aspiration. In addition, the
pharyngeal cancer group showed significant improvements in VDS and DIGEST
scores after the intervention. Conclusions: Our outcomes highlight the beneficial effects of singing for HNC patients
with dysphagia. The notable improvements in the pharyngeal phase suggest
that therapeutic singing would be more appropriate for HNC patients who need
to improve their intrinsic muscle movements of vocal fold and laryngeal
elevation.

Abstract
Background We compared the clinical outcomes of patients with oral cavity squamous cell carcinoma (OCSCC) with cN+pN0 versus cN0pN0 disease. Methods A total of 1309 OCSCC patients with pN0 disease were included. Of them, 1019 and 290 cases had cN0pN0 and cN+pN0 disease, respectively. For comparison purposes, we also examined 799 patients with pN+disease (cN0pN+/cN+pN+, n = 239/560). Subgroup analysis was performed in a propensity score‐matched cohort with cN0pN0 and cN+pN0 disease (n = 284 each). Results Compared with cN0pN0, patients with cN+pN0 had a higher prevalence of the following variables: betel chewing, pT3−4, depth ≥10 mm, perineural invasion, and treatment with surgery and adjuvant therapy. The prognosis of patients with cN+pN0 (mean: 52 nodes) and cN0pN0 (mean: 39 nodes) disease was similar both in the original cohort and after propensity score matching. However, the 5‐year outcomes were more favorable for cN+pN0/cN0pN0 compared with cN0pN+/cN+pN+ (local control, 88%/88%/83%/81%; neck control, 94%/93%/82%/76%; distant metastases, 4%/3%/13%/31%; disease‐free survival, 84%/83%/68%/52%; disease‐specific survival, 92%/92%/77%/57%; overall survival, 81%/82%/59%/42%; all p values <0.001; cN+pN0 versus cN0pN0, all p values >0.05). cN+pN0 disease (vs. cN0pN0) was not significantly associated with local control, neck control, distant metastases, and survivals either in univariable or multivariable analyses. Conclusions Despite a higher risk factor burden, the prognosis of patients with cN+pN0 disease did not differ from that of cases with cN0pN0. The higher nodal yield and the more frequent use of adjuvant therapy in cN+pN0 disease may explain the lack of significant differences in terms of neck control compared with cN0pN0 disease.

Poor tumor differentiation is an independent adverse prognostic variable in patients with locally advanced oral cavity cancer--Comparison with pathological risk factors according to the NCCN guidelines. Cancer Med 2021; 10:6627-6641.

Abstract
Methods We sought to compare the prognostic impact of tumor differentiation with respect to adverse risk factors (RFs) identified by the National Comprehensive Cancer Network (NCCN) guidelines––including extranodal extension (ENE), positive/close margins, perineural invasion, lymphatic invasion, and vascular invasion––in patients with locally advanced oral cavity squamous cell carcinoma (OCSCC). Results Between 1996 and 2018, 1179 consecutive patients with first primary pT3–4 OCSCC were included. A three‐level grading system was adopted––in which the final classification was assigned according to the most prevalent tumor grade. We identified 382/669/128 patients with well/moderately/poorly differentiated tumors, respectively. Compared with well/moderately differentiated tumors, poorly differentiated OCSCC had a higher prevalence of the following variables: female sex (4%/6%/11%), ENE, (14%/36%/61%), positive margins (0.5%/2%/4%), close margins (10%/14%/22%), perineural invasion (22%/50%/63%), lymphatic invasion (2%/9%/17%), vascular invasion (1%/4%/10%), and adjuvant therapy (64%/80%/87%). The 5‐year rates of patients with well/moderately/poorly differentiated OCSCC were as follows: local control (LC, 85%/82%/84%, p = 0.439), neck control (NC, 91%/83%/70%, p < 0.001), distant metastases (DM, 6%/18%/40%, p < 0.001), disease‐free survival (DFS, 78%/63%/46%, p < 0.001), disease‐specific survival (DSS, 85%/71%/49%, p < 0.001), and overall survival (OS, 68%/55%/39%, p < 0.001). Multivariable analysis identified the following variables as independent prognosticators for 5‐year outcomes: ENE (LC/NC/DM/DFS/DSS/OS), poorly differentiated tumors (NC/DM/DFS/DSS/OS), positive margins (LC/DFS), lymphatic invasion (DFS/DSS/OS), perineural invasion (DM), and age ≥65 years (OS). Conclusions In addition to ENE, poor tumor differentiation was identified as the second most relevant adverse RF for patients with pT3–4 OCSCC. We suggest that the NCCN guidelines should include poor tumor differentiation as an adverse RF to refine and tailor clinical management.

Objective: The main aim of this study was to establish a scoring model to predict risk of progression and survival in patients with regionally recurrent nasopharyngeal carcinoma (NPC). Methods: Three hundred and forty-eight patients subjected to neck dissection from 2003 to 2017 were included for study. Clinicopathologic information for each patient was analyzed. Independent prognostic factors were selected using the Cox proportional hazards model and incorporated into the scoring model. Concordance index (C-index) and calibration curves were used to verify discrimination and calibration, respectively and the results validated using bootstrap resampling. Results: Microscopic positive lymph node > 2 [hazard ratio (HR), 2.19; 95% confidence interval (CI), 1.30–3.68; P = 0.003], extranodal extension (HR, 2.75; 95% CI, 1.69–4.47; P < 0.001), and lower neck involvement (HR, 1.78; 95% CI, 1.04–3.04; P = 0.034) were identified from multivariate analysis as independent factors for overall survival (OS). A qualitative 4-point scale was generated to stratify patients into 4 risk groups for predicting OS and progression-free survival (PFS). The novel scoring model demonstrated enhanced discrimination (C-index = 0.69; 95% CI, 0.62–0.76) relative to the original recurrent tumor-node-metastasis (rTNM) staging system (C-index = 0.56; 95% CI, 0.50–0.62), and was internally validated with a bootstrap-adjusted C-index of 0.70. The calibration curve showed good agreement between predicted probabilities and actual observations. Conclusions: The scoring system established in this study based on a large regionally recurrent NPC cohort fills a gap regarding assessment of risk and prediction of survival outcomes after neck dissection in this population and could be further applied to identify high-risk patients who may benefit from more aggressive intervention.

Lymph Node Yield and Ratio in Selective and Modified Radical Neck Dissection in Head and Neck Cancer-Impact on Oncological Outcome. Cancers (Basel) 2021; 13:cancers13092205. [PMID: 34064344 PMCID: PMC8125696 DOI: 10.3390/cancers13092205] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2021] [Revised: 04/25/2021] [Accepted: 05/02/2021] [Indexed: 01/16/2023] Open
Abstract
Background: Lymph node metastases are associated with poor prognosis in head and neck squamous cell carcinoma (HNSCC). Neck dissection (ND) is often performed prior to or after (chemo)radiation (CRT) and is an integral part of HNSCC treatment strategies. The impact of CRT delivered prior to ND on lymph node yield (LNY) and lymph node ratio (LNR) has not been comprehensively investigated. Material and methods: A retrospective cohort study was conducted from January 2014 to 30 June 2019 at the University Hospital of Bern, Switzerland. We included 252 patients with primary HNSCC who underwent NDs either before or after CRT. LNY and LNR were compared in patients undergoing ND prior to or after CRT. A total of 137 and 115 patients underwent modified radical ND (levels I to V) and selective ND, respectively. The impact of several features on survival and disease control was assessed. Results: Of the included patients, 170 were male and 82 were females. There were 141 primaries from the oral cavity, 55 from the oropharynx, and 28 from the larynx. ND specimens showed a pN0 stage in 105 patients and pN+ in 147. LNY, but LNR was not significantly higher in patients undergoing upfront ND than in those after CRT (median: 38 vs. 22, p < 0.0001). Cox hazard ratio regression showed that an LNR ≥ 6.5% correlated with poor overall (HR 2.42, CI 1.12-4.89, p = 0.014) and disease-free survival (HR 3.416, CI 1.54-754, p = 0.003) in MRND. Conclusion: ND after CRT leads to significantly reduced LNY. An LNR ≥6.5% is an independent risk factor for decreased overall, disease-free, and distant metastasis-free survival for MRND.

Abstract
BACKGROUND Lymph node yield is an important prognostic factor in head and neck squamous cell carcinoma. Variability in neck dissection sampling techniques has not been studied as a determinant of lymph node yield. METHODS This retrospective study used lymph node yield and average nodes per level to compare level-by-level and en bloc neck dissection sampling methods, in primary head and neck squamous cell carcinoma cases operated between March 2017 and February 2020. RESULTS From 123 patients, 182 neck dissections were analysed, of which 133 were selective and the rest were comprehensive: 55 had level-by-level sampling and 127 had undergone en bloc dissection. The level-by-level method yielded more nodes in all neck dissections combined (20 vs 17; p = 0.097), but the difference was significant only for the subcohort of selective neck dissection (18.5 vs 15; p = 0.011). However, the gain in average nodes per level achieved by level-by-level sampling was significant in both groups (4.2 vs 3.33 and 4.4 vs 3, respectively; both p < 0.001). CONCLUSION Sampling of cervical lymph nodes level-by-level yields more nodes than the en bloc technique. Further studies could verify whether neck dissection sampling technique has any impact on survival rates.

Abstract
Metastasis, a powerful prognostic indicator of oral squamous cell carcinoma (OSCC), is chiefly responsible for poor cancer outcomes. Despite an increasing number of studies examining the mechanisms underlying poor outcomes, the development of potent strategies is hindered by insufficient characterization of the crucial regulators. Long noncoding RNAs (lncRNAs) have recently been gaining interest as significant modulators of OSCC metastasis; however, the detailed mechanisms underlying lncRNA-mediated OSCC metastasis remain relatively uncharacterized. Here, we identified a novel alternative splice variant of oral cancer overexpressed 1 (ORAOV1), named as ORAOV1-B, which was subsequently validated as an lncRNA and correlated with OSCC lymph node metastasis; significantly increased invasion and migration were observed in ORAOV1-B-overexpressing OSCC cells. RNA pulldown and mass spectrometry identified Hsp90 as a direct target of ORAOV1-B, and cDNA microarrays suggested TNFα as a potential downstream target of ORAOV1-B. ORAOV1-B was shown to directly bind to and stabilize Hsp90, which maintains the function of client proteins, receptor-interaction protein, and IκB kinase beta, thus activating the NF-κB pathway and inducing TNFα. Additionally, TNFα reciprocally enhanced p-NF-κB-p65 and the downstream epithelial-mesenchymal transition. ORAOV1-B effects were reversed by a TNFα inhibitor, demonstrating that TNFα is essential for ORAOV1-B-regulated metastatic ability. Consistent epithelial-mesenchymal transition in the ORAOV1-B group was demonstrated via an orthotopic model. In the metastatic model, ORAOV1-B significantly contributed to OSCC-related lung metastasis. In summary, the novel splice variant ORAOV1-B is an lncRNA, which significantly potentiates OSCC invasion and metastasis by binding to Hsp90 and activating the NF-κB-TNFα loop. These findings demonstrate the versatile role of ORAOV1 family members and the significance of genes located within 11q13 in promoting OSCC. ORAOV1-B might serve as an attractive OSCC metastasis intervention target.

Abstract
Context: Log odds of positive lymph nodes (LODDS) have been recently demonstrated as a very promising staging model and have outperformed AJCC pN, lymph node ratio (LNR) category in major cancers. Literature is scarce concerning the prognostic ability of LODDS in oral squamous cell carcinoma (OSCC) patients. Aims: The present study was aimed to evaluate the importance of LODDS in predicting locoregional recurrence and overall survival (OS) in patients with OSCC compared to LNR. Settings and Design: The retrospective study was carried out on 194 patients with OSCC cases treated by surgery ± adjuvant therapy from 2008 to 2014 at our institution. Subjects and Methods: Demographical and clinicopathological details of study cases were recorded. LNR and LODDS were calculated and expressed as a percentage and mean ± standard deviation. Statistical Analysis Used: The OS analysis was done by the Kaplan–Meier curve followed by log-rank (mantel-cox) test. Univariate and multivariate survival analysis was done to analyze the prognostic ability of LNR% and LODDS after adjusting the clinicopathological parameters by the Cox proportional hazards model. Results: Patients with cut off values of LODDS >−1.2 and LNR% >4 had significantly lower mean OS (P ≤ 0.001). Multivariate analysis indicated that only mean LODDS >−1.2 was significantly associated with poor OS. Although there was a correlation with locoregional recurrence, LODDS and LNR failed to be the independent predictors of locoregional recurrence. Conclusions: LODDS was an independent reliable prognostic indicator for patients with OSCCs than conventional staging systems and LNR.

Abstract
The presence of Lymph node metastasis with extranodal extension (ENE) is considered to be an important adverse prognostic factor for survival in patients with head and neck cancer. The aim of this study was to determine the prognostic significance of ENE in patients with laryngeal squamous cell carcinoma (LSCC). Three hundred and fifty-five patients with LSCC who underwent surgical resection and neck dissection were included. The status of cervical lymph node was classified into three groups: pathological negative nodal (pN-), pathological positive nodal without ENE (ENE-), and pathological positive nodal with ENE (ENE+). A total of 85 of 355 (23.9%) LSCC were pathological nodal positive, and ENE was detected in 22/355 (6.2%) patients. ENE was associated with drinking (p=0.005), T stage (p=0.000), tumor location (p=0.000), and differentiation degree (p=0.000). The number of lymph node metastasis in ENE+ group was associated with almost twice compared to ENE- group (p=0.005). The 5-year overall survival rates for patients in the pN-, ENE-, and ENE+ groups were 86.4±2.6%, 75.9±6.3%, and 53.7±12.7%, respectively (p=0.000). After adjusting for confounding variables, ENE+ was associated with more than five times the hazard of death than pN- cases (p=0.000), and more than twice the hazard of death than ENE- cases (p=0.036). Compared to N2-3/ENE- cases, N2-3/ENE+ cases had the poorest survival rate (p=0.013). ENE+ was associated with worse outcomes compared to pN - or ENE- status. ENE is an independent prognostic factor in LSCC, and could be an indicator of the need for adjuvant treatment.

Abstract
Circular RNAs (circRNA) are a new member of endogenously produced noncoding RNAs that have been characterized as key regulators of gene expression in a variety of malignances. However, the role of circRNA in oral squamous cell carcinoma (OSCC) remains largely unknown. In this study, we identified unique circRNA that regulate OSCC progression and metastasis and pave roads for future research in early diagnosis, prevention, and treatment of OSCC. Transcriptomic analyses identified a circRNA derived from IGHG locus (circIGHG) as significantly upregulated in OSCC and positively associated with poor prognosis of OSCC. circIGHG directly bound miR-142-5p and consequently elevated IGF2BP3 activity. Knockdown of circIGHG led to impaired expression of IGF2BP3 and attenuated aggressiveness of OSCC cells. Epithelial-mesenchymal transition was the main mechanism through which circIGHG/IGF2BP3 promotes metastasis of OSCC. Overall, these results demonstrate that circIGHG plays a pivotal role in OSCC development and metastasis and has potential to serve as a biomarker and therapeutic target for early-stage diagnosis and treatment of OSCC. SIGNIFICANCE: These findings broaden our insights regarding regulation of OSCC progression by circular RNA and serve as a reference for future clinical research in OSCC diagnosis and treatment.

Abstract
INTRODUCTION Lymph node metastasis is a poor prognostic indicator and is well established in tongue squamous cell carcinoma. Based on the current staging system, accurate risk stratification is difficult. There is thus a need to evaluate an alternate method for predicting recurrence and survival. The objective of the study was to evaluate lymph node ratio as a prognostic marker as compared with N-staging for tongue squamous cell carcinoma. MATERIALS AND METHODS We conducted a retrospective cohort study with 56 patients with a lymph node ratio greater than 0.012 (exposed) and 74 patients with a lymph node ratio less than 0.012 (unexposed). Overall five-year survival and disease-free survival were assessed. The Cox proportional hazard model was used to analyse lymph node ratio as a predictor of outcome, together with other covariates. RESULTS A total of 130 patients were included in the study. Patients with lymph node ratio greater than 0.012 had a poor overall five-year (mean survival time 52.1 months vs 38.1 months) and disease-free survival (mean survival time 53.6 months vs 39.2 months). The hazard of death among patients with a lymph node ratio greater than 0.012 was 3.24 times higher than the hazard of death among patients with a lymph node ratio less than 0.012 (95% confidence interval 1.82-5.77). DISCUSSION Lymph node ratio is a superior prognostic marker compared with the currently used American Joint Committee on Cancer N-staging. Our findings also suggest that the margin status (involved) of the primary tumour resection adversely affects prognosis.

Abstract
Background/purpose The status of neck lymph nodes (LNs) plays an important role in survival of oral cavity cancer. Early stage oral cancer patients are still at a risk for locoregional metastasis. We aimed to determine the number of LNs that needs to be retrieved for adequate diagnosis and treatment of the neck tumor. Materials and methods We conducted a retrospective study of 126 oral cavity cancer patients who underwent wide excision and 3 types of neck dissection at MacKay Memorial Hospital, Taiwan. Data from the operative and pathology reports were collected and analyzed. The significant difference was defined as p < 0.05 by SPSS 21.0 and Prizm 5 software. Results There was a significant difference between the total retrieved LNs and tumor differentiation and nerve invasion on multivariate analysis. Receiveroperating characteristic (ROC) curve showed significant difference in the total number of neck LNs between the survival and expired groups. The cut-off point was 36.5 nodes. However, there was no difference in survival between supraomohyoid and modified radical neck dissection. Conclusion Retrieval of adequate LNs can improve oral cancer survival rates. If total number of neck nodes examined is <37 with poor differentiation and/or nerve invasion, early oral cancer patients with neck dissection have a lower survival rate and are candidates for adjuvant therapy.

Abstract
INTRODUCTION AND OBJECTIVES Lymph node density or lymph node ratio (LNR), defined as the quotient between the total number of positive lymph nodes and the total number of dissected lymph nodes, has demonstrated a prognostic capacity in several tumour models, including patients with head and neck squamous cell carcinomas (HNSCC). The aim of the present study is to analyse the prognostic value of LNR in a wide cohort of patients with HNSCC. METHODS We carried out a retrospective study of a cohort of 1,311 patients with HNSCC treated with unilateral or bilateral neck dissections. Of the patients included in the study, 55.0% had lymph node metastases (pN+). We proceeded to calculate the value of the LNR, and its categorization through a recursive partition analysis considering specific survival as the dependent variable. RESULTS Three categories were defined according to the value of the LNR with a cut-off point at the values < of .025 and .118. The 5-year specific survival for patients with an LNR less than .025 (n=654, 49.8%) was 87.2%, for patients with a LNR .025-.118 (n=394, 30.1%) it was 51.6%, and for patients with a LNR greater than .188 (n=263, 20.1%) it was 27.3% (P=.0001). According to the results of a multivariate analysis, the LNR significantly related to specific survival. CONCLUSION The LNR can be a prognostic variable to be considered in the pathological staging of the lymph nodes.

Abstract
Background Oral cancer is the most common cancer among Indian men, and has strong tendency of metastatic spread to neck lymph node which strongly influences prognosis especially 5 year survival-rate and also guides the related managements more effectively. Therefore, a reliable and accurate means of preoperative evaluation of extent of nodal involvement becomes crucial. However, earlier researchers have preferred to address mainly its dichotomous form (involved/not-involved) instead of ordinal form while dealing with epidemiology of nodal involvement. As a matter of fact, consideration of ordinal form appropriately may increase not only the efficiency of the developed model but also accuracy in the results and related implications. Hence, to develop a model describing factors associated with ordinal form of nodal involvement was major focus of this study. Methods The data for model building were taken from the Department of Surgical Oncology, Dr.BRA-IRCH, AIIMS, New Delhi, India. All the OSCC patients (duly operated including neck dissection) and confirmed histopathologically from 1995 to 2013 were included. Further, another data of 204 patients collected prospectively from 2014 to 2015 was considered for the validation of the developed model. To assess the factors associated with extent of nodal involvement, as a first attempt in the field of OSCC, stepwise multivariable regression procedure was used and results are presented as odds-ratio and corresponding 95% confidence interval (CI). For appropriate accounting of ordinal form, the ordinal models were assessed and compared. Also, performance of the developed model was validated on a prospectively collected another data. Results Under multivariable proportional odds model, pain at the time of presentation, sub mucous fibrosis, palpable neck node, oral site and degree of differentiation were found to be significantly associated factors with extent of nodal involvement. In addition, tumor size also emerged to be significant under partial-proportional odds model. Conclusions The analytical results under the present study reveal that in case of ordinal form of the outcome, appropriate ordinal regression may be a preferred choice. Present data suggest that, pain, sub mucous fibrosis, palpable neck node, oral site, degree of differentiation and tumor size are the most probable associated factors with extent of nodal involvement.

Abstract
Importance Oral cavity squamous cell carcinoma (OCSCC) is associated with often-delayed clinical diagnosis, poor prognosis, and expensive therapeutic approaches. Prognostic accuracy is important in improving treatment outcomes of patients with this disease. Objectives To assess lymph node ratio (LNR) and other factors in estimating response to treatment and provide prognostic information helpful for clinical decision making. Design, Setting, and Participants A retrospective cohort study was conducted from January 1, 2000, to December 31, 2015, at an academic hospital in Denver, Colorado. Participants included 149 patients with primary OCSCC who received curative-intent surgery and/or postoperative adjuvant therapies. Analysis was performed from December 8, 2017, to August 15, 2018. Main Outcomes and Measures Overall survival (OS), disease-free survival (DFS), locoregional disease-free survival (LRDFS), and distant metastasis-free survival (DMDFS) adjusted for known prognostic risk factors, as well as correlation of LNR with other histopathologic prognostic factors. Results Of the 149 patients included in analysis, 105 were men (70.5%); the median age at diagnosis was 59 years (range, 28-88 years). Using the Kaplan-Meier method, the 5-year survival estimates for OS rate was 40.4% (95% CI, 31.3%-49.3%); DFS, 48.6% (95% CI, 38.6%-58.0%); LRDFS, 57.7% (95% CI, 46.6%-67.2%); and DMDFS, 74.7% (95% CI, 65.1%-82.0%). The median follow-up was 20 months for all patients and 34.5 months (range, 0-137 months) for surviving patients. Nonwhite race (hazard ratio [HR], 2.15; 95% CI, 1.22-3.81), T3-T4 category (HR, 1.99; 95% CI, 1.18-3.35), and LNR greater than 10% (HR, 2.71; 95% CI, 1.39-5.27) were associated with poorer OS. Nonwhite patients also had higher risk of locoregional failures (HR, 2.47; 95% CI, 1.28-4.79), whereas women were more likely to have distant metastasis (HR, 2.55; 95% CI, 1.14-5.71). Floor-of-mouth subsite had fewer locoregional recurrences than did other subsites (HR, 0.45, 95% CI, 0.21-0.99). An LNR greater than 10% independently was associated with worse OS (HR, 2.71; 95% CI, 1.39-5.27), DFS (HR, 2.48; 95% CI, 1.18-5.22), and DMDFS (HR, 6.05; 95% CI, 1.54-23.71). The LNR was associated with N-stage (Cramer V, 0.69; 95% CI, 0.58-0.78), extracapsular extension (Cramer V, 0.55; 95% CI, 0.44-0.66), lymphovascular invasion (Cramer V, 0.46; 95% CI, 0.27-0.61); number of excised lymph nodes (Cramer V, 0.24; 95% CI, 0.06-0.37), margin (Cramer V, 0.22; 95% CI, 0.05-0.38), and tumor thickness combined with depth of invasion (Cramer V, 0.25; 95% CI, 0.05-0.38). Conclusions and Relevance Locoregional treatment failure remained the predominant pattern of failure. An advanced pathologic stage and nonwhite race were found to be associated with worse outcomes. The findings from this study suggest that LNR is the most robust prognostic factor and appears to have implications for risk stratification in this disease.

Abstract
Background: Routine changes in cell metabolism can drive tumor development, as the cellular program develops to promote glycolysis and redox homeostasis during tumor progression; however, the associated mechanisms in tongue squamous cell carcinoma (TSCC) remain unclear. Methods: We investigated methylenetetrahydrofolate dehydrogenase 1-like (MTHFD1L) expression, its clinical relevance, redox modification, and molecular mechanisms using TSCC cells and tissues. The anti-tumor effects of MTHFD1L knockdown on TSCC tumorigenesis were evaluated in vitro and in vivo. Kaplan-Meier curves and the log-rank test were used to analyze disease-free survival and overall survival. Results: TSCC patients with high expression levels of MTHFD1L had shorter overall survival (P < 0.05) and disease-free survival (P < 0.05). Knockdown of MTHFD1L reduced nicotinamide adenine dinucleotide phosphate (NADPH) levels and increased reactive oxygen species (ROS), which accelerated cell death under oxidative stress, such as hypoxia or glucose deprivation. Additionally, inhibition of MTHFD1L suppressed TSCC cell growth and delayed the cell cycle, including in xenograft experiments. Conclusions: MTHFD1L confers redox homeostasis and promotes TSCC cell growth, which provides a great opportunity to study tumor metabolism in head and neck cancer. The mTORC1-4EBP1-eIF4E axis may affect the expression of MTHFD1L in TSCC. Inhibition of the expression of MTHFD1L may be an actionable and effective therapeutic target in TSCC.

Abstract
Carcinoma ex-pleomorphic adenoma (CEPA), an extremely aggressive malignant tumor, bears a significant potential for locoregional recurrence and distant metastases. Management of the disease usually involves definitive surgery with postoperative radiotherapy administered for identified nodal metastases. Two cases of CEPA with many (>50) cervical lymph node metastases and other histopathological features were managed by tri-modality treatment scheme. No evidence of disease occurred during follow-up of at least 2 years. These cases may eventually establish the value of surgery with adjuvant radiochemotherapy in patients with CEPA and supernumerary nodal metastases.

Abstract
It is known that lymph node metastasis lowers the survival rates in laryngeal carcinoma. This study aimed to investigate the effect of extranodal extension in lymph node metastasis on survival. The demographic characteristics and histopathologic results of 81 patients who underwent total laryngectomy and neck dissection due to advanced larynx squamous cell carcinoma between 2011 and 2018 were reviewed retrospectively. The patients were divided into 3 groups by lymph node metastasis status as reactive lymph node (group 1), lymph node metastasis without detected extranodal extension (group 2), and lymph node metastasis with detected extranodal extension (group 3). Survival analysis was performed between these 3 groups. In the patient population with a mean age of 61.56 years consisting of 6 females and 75 males, demographic characteristics between groups were comparable. Overall survival (OS) rates were detected to be 81% in group 1, 69.2% in group 2, and 61.5% in group 3. Two-year OS rates were detected to be 66.7% in group 1, 46.2% in group 2, and 38.5% in group 3. Statistical difference was detected between group 1 and group 3 both for OS and 2-year OS (P = .014, P = .008, respectively). No statistical difference was detected between group 2 and group 1, and between group 2 and group 3. In this study, we found a negative effect of detecting neck lymphadenopathy metastasis and extranodal extension on survival in patients who underwent total laryngectomy and neck dissection due to advanced laryngeal carcinoma.

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.

Abstract
PURPOSE The aim of the current work is to provide evidence-based recommendations to practicing physicians and others on the management of the neck in patients with squamous cell carcinoma of the oral cavity and oropharynx. METHODS ASCO convened an Expert Panel of medical oncology, surgery, radiation oncology, and advocacy experts to conduct a literature search, which included systematic reviews, meta-analyses, randomized controlled trials, and prospective and retrospective comparative observational studies published from 1990 through 2018. Outcomes of interest included survival, regional disease control, neck recurrence, and quality of life. Expert Panel members used available evidence and informal consensus to develop evidence-based guideline recommendations. RESULTS The literature search identified 124 relevant studies to inform the evidence base for this guideline. Six clinical scenarios were devised; three for oral cavity cancer and three for oropharynx cancer, and recommendations were generated for each one. RECOMMENDATIONS For oral cavity cancers, clinical scenarios focused on the indications for and the hallmarks of a high-quality neck dissection, indications for postoperative radiotherapy or chemoradiotherapy, and whether radiotherapy alone is sufficient elective treatment of an undissected neck compared with high-quality neck dissection. For oropharynx cancers, clinical scenarios focused on hallmarks of a high-quality neck dissection, factors that would favor operative versus nonoperative primary management, and clarifying criteria for an incomplete response to definitive chemoradiation for which salvage neck dissection would be recommended. Consensus was reached and recommendations were made for all six clinical scenarios. Additional information is available at www.asco.org/head-neck-cancer-guidelines .

Abstract
Korean Society of Thyroid-Head and Neck Surgery appointed a Task Force to provide guidance on the implementation of a surgical treatment of oral cancer. MEDLINE databases were searched for articles on subjects related to “surgical management of oral cancer” published in English. Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. The quality of evidence was rated with use RoBANS (Risk of Bias Assessment Tool for Nonrandomized Studies) and AMSTAR (A Measurement Tool to Assess the Methodological Quality of Systematic Reviews). Evidence-based recommendations for practice were ranked according to the American College of Physicians grading system. Additional directives are provided as expert opinions and Delphi questionnaire when insufficient evidence existed. The Committee developed 68 evidence-based recommendations in 34 categories intended to assist clinicians and patients and counselors, and health policy-makers. Proper surgical treatment selection for oral cancer, which is directed by patient- and subsite-specific factors, remains the greatest predictor of successful treatment outcomes. These guidelines are intended for use in conjunction with the individual patient’s treatment goals.

Multicenter retrospective study of the prognosis and treatment outcomes of Japanese oral squamous cell carcinoma patients with level IV/V metastasis. Head Neck 2019; 41:2256-2263. [PMID: 30708395 DOI: 10.1002/hed.25672] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2018] [Revised: 12/04/2018] [Accepted: 01/15/2019] [Indexed: 11/08/2022] Open
Abstract
BACKGROUND The purpose of this study was to retrospectively describe the characteristics and outcomes of patients with oral squamous cell carcinoma and level IV/V metastasis and to compare patients who underwent no postoperative therapy with those who underwent postoperative radiotherapy (RT) and concomitant chemoradiotherapy (CCRT). METHODS We evaluated 669 patients. Clinicopathological data, postoperative therapy, and clinical course were investigated. RESULTS Sixty-one patients (9.1%) developed level IV/V metastasis. The 3-year cumulative overall survival rates of patients with and without level IV/V metastasis were 47.3% and 64.3%, respectively. Tongue tumors, pN2 or N3 classification, and moderate or poor differentiation were significantly associated with the development of level IV/V metastasis. The surgery+RT/CCRT group was associated with better 3-year cumulative disease-specific survival and overall survival rates than the surgery only group. CONCLUSION Adjuvant therapy (RT alone or CCRT) after surgery is recommended for patients with level IV/V metastasis.

CCR4 Expression Is Associated With Poor Prognosis in Patients With Early Stage (pN0) Oral Tongue Cancer. J Oral Maxillofac Surg 2018; 77:426-432. [PMID: 30395826 DOI: 10.1016/j.joms.2018.09.035] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2018] [Revised: 09/02/2018] [Accepted: 09/24/2018] [Indexed: 12/18/2022]
Abstract
PURPOSE Chemokine receptors are involved in tumor metastasis and can predict poor prognosis; however, the expression and clinicopathologic relevance of chemokine receptors in early-stage cancer remain largely unknown. This study measured the association between chemokine (C-C motif) receptor-4 (CCR4) expression and prognosis in patients with histologically node-negative (pN0) oral tongue cancer. MATERIALS AND METHODS A retrospective analysis of CCR4 expression data from a consecutive case series of patients with pN0 oral cancer tongue was conducted. The expression of CCR4 by immunohistochemistry was investigated and the association between CCR4 expression and clinicopathologic variables and overall and disease-free survivals was evaluated using Kaplan-Meier analysis and a Cox regression model. RESULTS CCR4 expression was examined in 128 human tongue cancerous samples (109 tongue squamous cell carcinomas [TSCCs] and 19 other types) and 10 normal tongue samples and was found to be highly expressed in tumor tissues compared with normal tissues. CCR4 expression was observed in 64.2% of patients with TSCC and showed a significant association with tumor stage (P = .037). Patients with CCR4-positive expression exhibited poorer overall and disease-free survivals compared with those with CCR4-negative expression (P < .001 and P = .001), and CCR4-positive expression was an independent factor of unfavorable overall and disease-free survivals (P = .002 and P = .007). CONCLUSIONS This study identified CCR4 as a potential prognostic biomarker for recurrence and survival of patients with pN0 oral tongue cancer. Thus, CCR4 might be a possible therapeutic target for patients with early-stage cancer.
