Head Neck 2023; 45:2489-2497. [PMID: 37522839 DOI: 10.1002/hed.27459] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Revised: 06/22/2023] [Accepted: 07/04/2023] [Indexed: 08/01/2023] Open
Abstract
BACKGROUND Metastatic lymph node involvement influences therapy decisions and serves as a prognostic indicator in oral squamous cell carcinoma (OSCC). However, many early-stage patients with clinically negative lymph nodes exhibit no metastasis upon surgical staging. This study aimed to identify differentially expressed miRNAs capable of distinguishing pathologically positive (pN+) from negative (pN0) nodes in OSCC patients without clinical evidence of lymph node metastases (cN0). METHODS Expression levels of 798 miRNAs were assessed in tumor samples from 10 pN+ and 10 pN0 patients using the Nanostring nCounter platform. Validation was performed in an independent cohort of 15 pN+ and 24 pN0 patients through RT-qPCR. RESULTS Eight miRNAs exhibited differential expression between pN0 and pN+ patients. Notably, hsa-miR-99a-5p demonstrated high sensitivity and specificity in predicting patients at higher risk of positive lymph nodes. CONCLUSIONS These findings highlight hsa-miR-99a-5p as a potential biomarker for detecting lymph node metastasis in primary OSCC tumors.

Abstract
BACKGROUND Lymph node metastasis (LNM) is considered as an adverse prognostic indicator for cancer patients. Preoperative knowledge of LNM is valuable for pretreatment decision making. Here, we sought to develop and validate an LNM signature for preoperative prediction of LNM in patients with head and neck squamous cell carcinoma (HNSCC). METHODS By studying single cell RNA-sequencing data (scRNA-seq), differentially expressed mRNA were selected and analyzed through univariate logistic regression and least absolute shrinkage and selection operator (LASSO) to identify an LNM signature. Multivariate logistic regression was utilized to establish an LNM nomogram incorporating LNM signature and T-classification. RESULTS The LNM signature was significantly associated with lymph node status and prognosis. The LNM signature and LNM nomogram displayed a robust predictive effect. CONCLUSION Our study reveals that LNM signature is a powerful biomarker for preoperative prediction of LNM in patients with HNSCC, which may be effective to realize individualized outcome prediction.

Abstract
Background The prognostic reliability of the UICC's TNM classification (8th edition) for human papillomavirus (HPV)‐positive tonsillar squamous cell carcinomas (TSCCs) compared to the 7th edition was explored, and its improvement by using additional anatomical and nonanatomical parameters. Methods One hundred and ten HPV‐positive and 225 HPV‐negative TSCCs were retrospectively analyzed. Survival was correlated with patient and tumor characteristics (7th and 8th edition UICC TNM classification). Results In HPV‐positive TSCCs, the 8th edition UICC's TNM classification correlated better with prognosis than the 7th edition. Also, smoking status was a stronger prognosticator of survival than UICC staging. Non‐ or former smokers had a 5‐year overall survival of 95.1% regardless of tumor stage. Furthermore, age (>65 years), cN3, and M1 classification were significant prognostic factors. Conclusion The prognostic value of the 8th edition UICC's TNM classification improved significantly when compared to the 7th edition. Nonetheless, further improvement is possible by adding nonanatomical factors (smoking, age >65 year) and separating N0‐N2 from N3.

Presentation and outcomes of patients with clinically T1-2, N0 supraglottic squamous cell carcinoma: The role of definitive radiotherapy compared to primary partial laryngectomy. Head Neck 2021; 44:735-744. [PMID: 34964526 DOI: 10.1002/hed.26966] [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: 04/25/2021] [Revised: 11/14/2021] [Accepted: 12/10/2021] [Indexed: 11/11/2022] Open
Abstract
BACKGROUND Early-stage supraglottic squamous cell carcinoma (SCC) is usually treated with a single modality. The aim of this study is to examine the role of radiotherapy (RT) versus partial laryngectomy (open, robotic-assisted, or endoscopic) with elective neck dissection (PL + END). METHODS A retrospective analysis of the National Cancer Database, 2010-2016. The study population included adult patients with clinically T1-2, N0 supraglottic SCC. RESULTS 3301 patients were included. RT was performed in 93.52%, open PL + END in 2.64%, robotic-assisted PL + END in 1.33%, and endoscopic surgical resection in 2.51%. In the surgery group, T was upstaged in 23.36% and N was upstage in 16.36%. Five-year survival in the primary surgery group compared to RT group was 61.89% versus 77.46% (HR: 0.56, 95%CI: 0.43, 0.72). CONCLUSIONS T was upstaged in 23% of surgical patients. This accurate staging is likely missed in patients who undergo RT and possibly contributes to lower overall survival of this treatment group.

Abstract
Desmosomes are intercellular adhesion complexes involved in various aspects of epithelial pathophysiology, including tissue homeostasis, morphogenesis, and disease development. Recent studies have reported that the abnormal expression of various desmosomal components correlates with tumor progression and poor survival. In addition, desmosomes have been shown to act as a signaling platform to regulate the proliferation, invasion, migration, morphogenesis, and apoptosis of cancer cells. The occurrence and progression of head and neck cancer (HNC) is accompanied by abnormal expression of desmosomal components and loss of desmosome structure. However, the role of desmosomal components in the progression of HNC remains controversial. This review aims to provide an overview of recent developments showing the paradoxical roles of desmosomal components in tumor suppression and promotion. It offers valuable insights for HNC diagnosis and therapeutics development.

Abstract
PURPOSE Several researchers have proposed and investigated the prognostic implications of various parameters, but have failed to provide concrete evidence regarding the inclusion or exclusion of histopathological features while clinically managing an oral squamous cell carcinoma (OSCC) case. The study purpose was to measure the prognostic values of a set of key histologic features and its association with its clinical outcome-5-year survival. MATERIALS AND METHODS This is a prospective cohort study and the sample was composed of patients treated for OSCC (April 2014 - March 2015). The predictor variables included pattern of tumor invasion (POI), stromal inflammation, angiogenesis, and vascular invasion with the outcome being survival of subjects observed over this 5-year period. Sociodemographic data (age, sex, marital status, systemic disease, habits etc), clinical staging and TNM staging were also recorded. We used multivariate regression analysis for predictor analysis; Kaplan-Meier survival curves and Cox hazard modeling was also performed using the data. RESULTS This article includes 50 subjects with a mean age of 54.94 years and 58% were male and their characteristics collected at the baseline and at a 12-, 24-, 36-, 48-, and 60-month follow-up. The overall 5-year survival was 48%. We saw a significant association between N-stage and POI (0.027), T-stage and mean vascular density (0.042), and T-stage and vascular invasion (0.046). POI, angiogenesis, and vascular invasion were found as significant predictors of overall 5-year survival (P < .001). CONCLUSIONS This study shows that histopathological parameters such as POI are important while determining the clinical outcome of OSCC. Histopathological parameters such as angiogenesis and vascular invasion can provide valuable information about the overall survival and prognosis.

Abstract
INTRODUCTION Oral cancer is one of the leading causes of mortality, and its worsening impact on the society has revealed the danger it poses in the coming future. Several researchers proposed and investigated the prognostic implications of various clinicopathologic and histopathologic parameters. AIM AND OBJECTIVES The aim of this study--assessing significance of histopathological features like pattern of tumor invasion, stromal inflammation, angiogenesis and vascular invasion on the clinical outcome of oral squamous cell carcinoma any possible correlations between the parameters, TNM Staging and prognosis were assessed and evaluated for a 5-year period. MATERIALS AND METHODS This study includes description of 50 diagnosed cases (mean age: 61.40, 29 males, and 21 females) of oral squamous cell carcinoma and their characteristics collected at baseline and at a 12-month follow up. The cases were grouped on the basis of their histological grade (well-differentiated, moderately differentiated, and poorly-differentiated). RESULTS All the data collected was tabulated in a baseline descriptive table, and all the parameters were compared between the 3 different histological groups. On cross-tabulations we found statistical significant difference the parameters of stromal inflammation with recurrence, clinical stage with T-stage, T-stage with N-stage, and N-stage with clinical stage. On analysis of the follow up we found 16 patients (32%) with recurrence and 9 patients (18%) succumb to the disease. CONCLUSION This study provides a significant insight on the importance of a combined histopathological analysis and clinical staging process to deliver an accurate prognostic opinion and also subsequently effect the treatment protocol.

Abstract
The study is aimed at establishing the purpose of tumour markers, their application, classification, diagnostic and therapeutic roles in the management of head and neck cancer. A literature review using Medline, Scopus, Google Scholar, the Cochrane Database of Systematic Reviews and the Cochrane central register of controlled trials for articles published between 1993 and 2016 on tumour markers and their role in head and neck cancer was performed. A broader search of prognostic markers in head and neck cancer was also carried out to avoid missing other pertinent markers. Natural history, tumour biology, stage and prognostic factors influence the outcome of management in patients with Head and Neck Squamous cell carcinoma (HNSCC). Evaluation of the cellular lineage and histogenic origin of diverse neoplasms can be done using tumour biomarkers. Identifying predictive tumour markers can lead to improvement in preventive management of HNSCC. There has been remarkable advancement in molecular technology with gene expression and proteomic profiling. Integration of specific tumour markers into routine clinical practice requires substantiation through well designed clinical trials. The investigation of tumour markers is imperative as they influence the prognosis of HNSCC and provide the potential to improve outcomes of treatment through targeted therapy. We have outlined recent tumour biomarkers in this review which have significant role in diagnosis, screening and prognostication in HNSCC. Recent advancement in clinical applications, therapeutic strategies of tumour markers has been highlighted.

Abstract
Angiopoietin-1 (Ang1) is a binding partner of endothelial cell-specific tyrosine-protein kinase receptor (Tie2), which serves important roles in vascular development and angiogenesis. Tie2 is closely associated with the metastasis of oral squamous cell carcinomas (OSCCs) however, little is known about the correlation between Tie2 and Ang1. In the present study, the functional mechanisms of the Tie2/Ang1 interaction were investigated using Tie2 overexpressed (oeTie2) OSCC cells and recombinant Ang1 protein. oeTie2 cells had increased cell-cell and cell-extracellular matrix adhesions compared with the control cells. Additionally, the adhesive activities increased following treatment with exogenous Ang1, indicating that Ang1 directly enhances Tie2 functions. In the clinical OSCC data from 10 cases positive for regional lymph node metastasis, all cases were negative for Tie2 expression and eight cases (80%) were negative for Ang1 expression. These results suggest that Tie2 and Ang1 serve important roles in cancer metastasis and may be potential biomarkers and therapeutic targets for OSCC metastasis.

Abstract
Tropomodulin1 (TMOD1), which regulates the length and depolymerization of actin filaments by binding to the pointed end of the actin filament, has been reported to be a powerful diagnostic marker for ALK-negative anaplastic large-cell lymphoma; however, little is known about the relevance of TMOD1 in the behavior of oral squamous cell carcinoma (OSCC). We evaluated TMOD1 expression in OSCC-derived cell lines and primary OSCC samples (n=200) using quantitative reverse transcriptase-polymerase chain reaction, immunoblotting and semi-quantitative immunohistochemistry. We also analyzed the clinical correlation between TMOD1 expression status and clinical parameters in patients with OSCC and performed a prospective study using 40 primary OSCC samples. TMOD1 expression was upregulated significantly (p<0.05) in OSCC in vitro and in vivo compared with normal counterparts. TMOD1 expression also was correlated significantly (p=0.0199 and p=0.0064, respectively) with regional lymph node metastasis (RLNM) and 5-year survival rates. This prospective study also showed that high TMOD1 expression was seen in 12 (75%) of 16 cases in RLNM-positive patients and 9 (37.5%) of 24 cases in RLNM-negative patients. The current data provide the first evidence that TMOD1 expression is a critical biomarker for RLNM and prognosis of patients with OSCC.

Abstract
Head and neck squamous cell carcinomas (HNSCC) show diverse clinicopathological features and are mostly linked with poor outcome. In this study, we tested if the expression of tumor growth, cell cycle and basement membrane anchorage related biomarkers allow prognostic and clinicopathological stratification of HNSCC. Archived HNSCC samples from 226 patients included into tissue microarrays (TMA) were tested using immunohistochemistry. Histopathological evaluation and the analysis of immunostaining for EGFR, Ki67, p53, p16(ink4) and Collagen XVII proteins were carried out in digital whole slides. Statistical evaluation was carried out using Pearson's Chi-square test and Kaplan-Meier survival analysis. In the tested cohort, hypopharyngeal cancers had the least favorable, and glottic cancers had the most favorable prognosis. High Ki67 positive tumor cell fractions were associated with significantly worse prognosis and elevated rate of lymph node metastasis. Both Ki67 and EGFR expression correlated significantly with the tumor localization. Ki67 index was the highest in the hypopharyngeal region and it proved to be the lowest in the glottic region. EGFR expression was the highest in the oral cavity and the lowest in the glottic region. The survival rate of patients with p16(ink4)-negative cancer was significantly lower than of those with p16(ink4)-positive disease. A significant inverse correlation was found between histological grade and the prognosis of HNSCC. Our data support that elevated Ki67 positive proliferating cell fractions contribute to the unfavorable prognosis of hypopharyngeal cancers, while glottic cancers have the most favorable prognosis because of the lowest Ki67 expression rate.

Accuracy of microRNAs as markers for the detection of neck lymph node metastases in patients with head and neck squamous cell carcinoma. BMC Med 2015; 13:108. [PMID: 25956054 PMCID: PMC4493814 DOI: 10.1186/s12916-015-0350-3] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/23/2014] [Accepted: 04/20/2015] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND The presence of metastatic disease in cervical lymph nodes of head and neck squamous cell carcinoma (HNSCC) patients is a very important determinant in therapy choice and prognosis, with great impact in overall survival. Frequently, routine lymph node staging cannot detect occult metastases and the post-surgical histologic evaluation of resected lymph nodes is not sensitive in detecting small metastatic deposits. Molecular markers based on tissue-specific microRNA expression are alternative accurate diagnostic markers. Herein, we evaluated the feasibility of using the expression of microRNAs to detect metastatic cells in formalin-fixed paraffin-embedded (FFPE) lymph nodes and in fine-needle aspiration (FNA) biopsies of HNSCC patients. METHODS An initial screening compared the expression of 667 microRNAs in a discovery set comprised by metastatic and non-metastatic lymph nodes from HNSCC patients. The most differentially expressed microRNAs were validated by qRT-PCR in two independent cohorts: i) 48 FFPE lymph node samples, and ii) 113 FNA lymph node biopsies. The accuracy of the markers in identifying metastatic samples was assessed through the analysis of sensitivity, specificity, accuracy, negative predictive value, positive predictive value, and area under the curve values. RESULTS Seven microRNAs highly expressed in metastatic lymph nodes from the discovery set were validated in FFPE lymph node samples. MiR-203 and miR-205 identified all metastatic samples, regardless of the size of the metastatic deposit. Additionally, these markers also showed high accuracy when FNA samples were examined. CONCLUSIONS The high accuracy of miR-203 and miR-205 warrant these microRNAs as diagnostic markers of neck metastases in HNSCC. These can be evaluated in entire lymph nodes and in FNA biopsies collected at different time-points such as pre-treatment samples, intraoperative sentinel node biopsy, and during patient follow-up. These markers can be useful in a clinical setting in the management of HNSCC patients from initial disease staging and therapy planning to patient surveillance.

Abstract
Desmoglein 3 is one of seven desmosomal cadherins that mediate cell-cell adhesion in desmosomes. Desmosomes are the intercellular junctional complexes that anchor the intermediate filaments of adjacent cells and confer strong cell adhesion thus are essential in the maintenance of tissue architecture and structural integrity. Like adherens junctions, desmosomes function as tumour suppressors and are down regulated in the process of epithelial-mesenchymal transition and in tumour cell invasion and metastasis. However, recently several studies have shown that various desmosomal components, including desmoglein 3, are up-regulated in cancer with increased levels of expression correlating with the clinical stage of malignancy, implicating their potentiality to serve as a diagnostic and prognostic marker. Furthermore, in vitro studies have demonstrated that overexpression of desmoglein 3 in cancer cell lines activates several signal pathways that have an impact on cell morphology, adhesion and locomotion. These additional signalling roles of desmoglein 3 may not be associated to its adhesive function in desmosomes but rather function outside of the junctions, acting as a key regulator in the control of actin based cellular processes. This review will discuss recent advances which support the role of desmoglein 3 in cancer progression.

Abstract
Lymph node metastasis is a major factor for poor prognosis in oral squamous cell carcinoma (OSCC). However, the molecular mechanisms of lymph node metastasis are unclear. We determined that angiopoietin-like protein 4 (ANGPTL4) mRNA and protein expression were increased in OSCC cells established from the primary site in metastatic cases. In addition, ANGPTL4 expression in biopsy specimens was correlated with the presence of lymph node metastasis. Therefore, our initial findings suggest that OSCC cells expressing ANGPTL4 may possess metastatic ability. Furthermore, cell culture supernatants from OSCC cells that metastasized to the lymph node contain ANGPTL4 and promote invasive ability. These findings suggest that secreted ANGPTL4 may affect the invasive ability of OSCC. Moreover, the rates of positive ANGPTL4 expression at the primary site were significantly higher in the lymph node metastasis group. These results demonstrate that ANGPTL4 contributes to OSCC metastasis by stimulating cell invasion. Therefore, ANGPTL4 is a potential therapeutic target for preventing cancer metastasis.

Abstract
BACKGROUND An increasing proportion of oropharyngeal squamous cell carcinomas (OPSCCs) is associated with human papillomavirus (HPV) type 16 infection. Several authors have suggested that HR-HPV DNA could be used as a marker of metastases in cervical cancers. Although HPV16 DNA has been detected in neck lymph node (LN) metastases of HPV16-positive OPSCC, its significance remains controversial. Does this presence correlate to metastatic involvement or is it just the consequence of LN filter function? OBJECTIVES This study aims to analyse the relationship between HPV16 detection in neck LNs of HPV16-positive OPSCC and their pathological status. STUDY DESIGN HP16-viral load (VL) was quantified by real-time-polymerase-chain reaction in primary tumours and neck LNs, in 11 patients with HPV16-positive OPSCC and in three patients with HPV16-negative OPSCC. HPV16 in situ hybridisation and p16 immunohistochemistry were performed in all LNs. RESULTS A total of 45 LN levels were assessed. HPV16 DNA was not identified in HPV16-negative OPSCC LNs. All metastatic LNs from HPV16-positive OPSCC had a high VL and the viral DNA was located within tumoural cells. Among 27 pathologically tumour-free LN (PTFLN) levels 16/27 had no detectable VL, whereas the VL was low or medium (<10(5)copies/million cells) in 8/27 and high (>10(5)copies/million cells) in 3/27 PTFLN. In the latter group, no metastatic cell was identified and the viral DNA was located in immune cells. CONCLUSION HPV16 detection in LN is explained by its presence within either metastatic cells or immune cells. HPV16 detection in PTFLN is not necessarily correlated to occult LN metastases.

Abstract
Metastasis to regional lymph nodes constitutes the main route toward progression and dissemination of head and neck carcinoma; at the same time it is the most significant adverse prognostic indicator for this disease. In recent years, significant focus has been given on the molecular mechanisms behind lymph node metastasis of head and neck cancer. The aim of this study is to assess the role of growth factor expression and function in association with lymph node metastasis and overall prognosis of head and neck cancer. Current literature, searching for experimental data regarding the molecular pathways of lymph node dissemination of head and neck cancer, is reviewed giving special emphasis on the expression and prognostic significance of specific growth factors. Members of the vascular endothelial growth factor (VEGF), mostly VEGF-C and VEGF-D, with their action through the receptors VEGFR-3 and VEGFR-2, constitute the most extensively studied growth factors associated with lymphangiogenesis so far. High expression of these as well as other molecules, including angiopoietins, insulin-like growth factor, and fibroblast growth factor, has been associated with lymph node metastasis and poor prognosis in head and neck squamous cell carcinoma. Numerous growth factors seem to play an important role regarding the lymph node metastatic potential of head and neck cancer. Further research is necessary in order to further clarify the molecular pathways and introduce novel therapeutic options.

Detection of metastatic head and neck squamous cell carcinoma using the relative expression of tissue-specific mir-205. Transl Oncol 2011; 1:202-8.

Abstract
The presence of cervical lymph node metastases in head and neck squamous cell carcinoma (HNSCC) is the strongest determinant of patient prognosis. Owing to the impact of nodal metastases on patient survival, a system for sensitive and accurate detection is required. Clinical staging of lymph nodes is far less accurate than pathological staging. Pathological staging also suffers limitations because it fails to detect micrometastasis in a subset of nodal specimens. To improve the sensitivity of existing means of diagnosing metastatic disease, many advocate the use of molecular markers specific for HNSCC cells. MicroRNA (miRNA) are short noncoding segments of RNA that posttranscriptionally regulate gene expression. Approximately one third of all miRNA will exhibit substantial tissue specificity. Using a quantitative reverse transcription-polymerase chain reaction-based assay, we examined the expression of microRNA-205 (mir-205) across tissues and demonstrated that its expression is highly specific for squamous epithelium. We applied this assay to tissue samples, and we could detect metastatic HNSCC in each positive lymph node specimen, whereas benign specimens did not express this marker. When compared to metastases from other primary tumors, HNSCC-positive lymph nodes were distinguishable by the high expression of this marker. Using an in vitro lymphoid tissue model, we were able to detect as little as one squamous cell in a background of 1 million lymphocytes. By combining the sensitivity of quantitative reverse transcription-polymerase chain reaction with the specificity of mir-205 for squamous epithelium, we demonstrate a novel molecular marker for the detection of metastatic HNSCC.

Abstract
PURPOSE Sentinel node biopsy (SNB) has been shown to accurately stage the regional lymphatics in oral carcinoma. However, intraoperative pathology is only moderately sensitive and final pathology takes several days to complete. The purpose of this study was to develop a rapid, automated, and quantitative real-time PCR (qRT-PCR) assay that can match final pathology in an intraoperative time frame. EXPERIMENTAL DESIGN Four hundred forty-eight grossly tumor-negative lymph nodes were evaluated for expression of 3 markers [PVA (pemphigus vulgaris antigen), PTHrP (parathyroid hormone-related protein), and TACSTD1 (tumor-associated calcium signal transducer 1)]. Conformity of metastasis detection by qRT-PCR was determined using hematoxylin and eosin and immunohistochemistry staining as the gold standard. PVA and TACSTD1 were then multiplexed with β-glucuronidase to develop a rapid, automated single-tube qRT-PCR assay using the Cepheid GeneXpert system. This assay was used to analyze 103 lymph nodes in an intraoperative time frame. RESULTS Four hundred forty-two nodes produced an informative result for both qRT-PCR and pathologic examination. Concordance of qRT-PCR for individual markers with final pathology ranged from 93% to 98%. The best marker combination was TACSTD1 and PVA. A rapid, multiplex assay for TACSTD1 and PVA was developed on the Cepheid GeneXpert and demonstrated an excellent reproducibility and linearity. Analysis of 103 lymph nodes demonstrated 94.2% accuracy of this assay for identifying positive and negative nodes. The average time for each assay to yield results was 35 minutes. CONCLUSIONS A rapid, automated qRT-PCR assay can detect lymph node metastasis in head and neck cancer with high accuracy compared to pathologic analysis and may be more accurate than intraoperative pathology. Combined, SNB and rapid qRT-PCR could more appropriately guide surgical treatment of patients with head and neck cancer.

Abstract
The authors compared N0 with N+ cases in neoadjuvant chemotherapy regression and recurrence. During a 12-year period, 180 consecutive oral squamous cell cancer patients were observed. Of these patients, 78 were N0 and 102 N+ stages. The drugs used were as follows: bleomycin, vincristine, methotrexate, and mitolactol. After three courses of chemotherapy, the regression (complete response (CR), partial response (PR), and no response (NR)) and side effect rate were determined. All patients were operated on and observed for the number and localization of recurrences during 3 year follow-up time. The N0 cases came from T2-3, while N+ was from T2-4a (AJCC 2002). The regression in the N0 group was CR 46%, PR 53%, and NR 1%; but in the N+ group, it was CR 12%, PR 72%, and NR 16%. The regression rate was significantly higher (p = 0.00025) for N0 group than N+ group. The regression rate for T3 N0 was significantly higher (p = 0.055) than for T3 N+ cases. In the N0 stage, the regression rate was significantly higher (p = 0.0174) for T2 than T3. In N+ stage, there was no significant difference (p = 0.183) for T2-4a. The side effects were slight. The recurrence rate for the N0 group was significantly lower (15%, p = 0.000069), while for N+ group, it was 59%. The dependence in the T3 cases was also significant (p = 0.009) in the 3-year tumor-free survival. The N stage seems a more important prognostic factor for chemotherapy response and recurrence rate than the T stage. Stage III can be divided into subgroups without metastasis (III.a) and with metastasis (III.b.), based on significant difference in regression and recurrence rate.

Abstract
CONCLUSION Duffy antigen receptor for chemokines (DARC), as a negative regulator, could attenuate the potential growth and metastasis of laryngeal squamous cell carcinoma (LSCC); hence it could be considered as a basis for a new prognostic aid and molecular therapeutic target in treating LSCC. OBJECTIVES To analyze the role of DARC in LSCC progression using LSCC clinical samples. METHODS A total of 65 LSCC tissues were examined immunohistochemically for DARC protein expression. The microvessel density (MVD) was determined by the endothelial cells immunostained using anti-CD34 antibody. RESULTS It was found that DARC was expressed in the LSCC samples, with a high expression in 32 of our cases (49.2%), and in lymph node-negative and -positive groups of 24 (72.7%) and 8 cases (25%), respectively (p < 0.01). MVD was (24.75 ± 5.45)/High power field (HP) and (32.58 ± 5.23)/HP in the cases with high and low expression of DARC, respectively (p < 0.01). More importantly, the DARC expression presented a strong negative correlation with nodal metastasis, with pTNM stage, and with recurrence, and the cases with a high DARC expression indicated a higher survival rate. In addition, the multivariate analysis showed that the DARC expression was an independent prognostic factor (p = 0.032; hazard ratio, 21.476; 95% confidence interval, 1.297-355.68).

Abstract
BACKGROUND The overall 5-year survival rate of approximately 60% for head and neck cancer patients has remained essentially unchanged over the past 30 years. MicroRNA-137 (miR-137) plays an essential role in cell-cycle control at the G1/S-phase checkpoint. However, the aberrant miR-137 promoter methylation observed in squamous cell carcinoma of the head and neck (SCCHN) suggests a tumor-specific molecular defect that may contribute to disease progression. METHODS The goal of this study was to assess, in formalin-fixed, paraffin-embedded tumor tissue, the association between miR-137 promoter methylation and survival (both overall and disease free) and with prognostic factors including stage, tumor size, lymph node positivity, tumor grade, and surgical tumor margin positivity. RESULTS The promoter methylation status of miR-137 was ascertained by methylation-specific polymerase chain reaction and detected in 11 of 67 SCCHN patients (16.4%), with no significant differences according to site (oral cavity, pharynx, larynx). Methylation of the miR-137 promoter was significantly associated with overall survival (hazard ratio, 3.68; 95% confidence interval, 1.01-13.38) but not with disease-free survival or any of the prognostic factors evaluated. CONCLUSIONS The results of this study indicate that miR-137 is methylated in tumor tissue from pharyngeal and laryngeal squamous cancers, in addition to oral squamous cell carcinoma, and that miR-137 promoter methylation has potential utility as a prognostic marker for SCCHN.

Abstract
Traditional diagnostic methods such as clinical assessment, histopathological examination and imaging techniques are limited in their capacity to provide information on prognosis and treatment choice of head and neck cancer. In recent years, molecular techniques have been developed that enabled us to get more insight into the molecular biological cellular pathways underlying tumor progression and metastasis. Correlation of these molecular changes with clinical events has been explored. However, consistently useful markers have not been identified yet, although many promising developments are in progress. It may be expected that in the near future, molecular markers will be useful for clinical purposes. In this paper, an overview will be given of the several molecular techniques that may have potential to be introduced in clinical practice in the management of head and neck squamous cell carcinoma.

Abstract
OBJECTIVE This study aimed to elucidate the differences in antitumor immune responses between primary tumors and metastatic regional lymph nodes in head and neck squamous cell carcinoma (HNSCC). STUDY DESIGN The clonality of tumor-infiltrating lymphocytes in tissue specimens from 17 HNSCC patients was examined regarding their T-cell receptor (TCR) repertoires and their complementary determining region 3 (CDR3) size spectratyping. Cytokine expression profiles and T-cell phenotypes also were measured by using real-time quantitative polymerase chain reaction. RESULTS The host immune responses to HNSCC cells, reflected by the TCR repertoire, differed between primary tumors and metastatic lymph nodes. CD8+-T cells and T helper type 1 (TH1)/T cytotoxic 1 (TC1) cell cytokine production in metastatic and nonmetastatic lymph nodes were similar. CONCLUSIONS The antitumor immune response to HNSCC cells changes during lymph node metastasis, and HNSCC cells can escape the cytotoxic immune responses mediated by CD8+-T cells and TH1/TC1 cells. These results suggest that lymph node metastasis might be associated with changes in the nature of the primary tumor antigens.

Abstract
Despite recent advances, the prognosis of oral squamous cell carcinoma is still poor. Therapeutic options such as radiotherapy, chemotherapy, surgery and the novel treatment option gene therapy are being investigated in animal models. Diverse models have been studied to induce oral squamous cell carcinomas. The carcinogenic 4-nitroquinoline-1-oxide (4NQO) model has proven to be successful although until now it is unknown at what time point the established tumor is a representative squamous cell carcinoma and has a suitable volume for scientific treatment. For this end we applied 4NQO 3 times a week during 16 weeks and measured the volume of tumor tissue each week until the end of the experiment at 40 weeks. Concurrent histopathology at different time points up to the end of the experiment revealed that all mice bearing oral tumors were diagnosed with squamous cell carcinoma. Immunohistochemistry with markers cyclin D1 and E-cadherin revealed that the generated mouse oral tumors showed strong similarities with the described immunopathology in human oral tumors. The 4NQO model is a suitable alternative for preclinical gene therapy experiments with primary oral tumors. Future survey of therapeutic options in the carcinogenic 4NQO model should be conducted around 40 weeks after the start of the treatment.

Abstract
Tumor-associated tissue eosinophilia (TATE) has been described in many sites, including head and neck. The aim of this study was to investigate the prevalence and possible role of TATE as a prognostic factor in oral squamous cell carcinoma (OSCC). Seventy-six consecutive patients with a diagnosis of OSCC were evaluated, and the number of eosinophils was obtained in 3 different areas in the tumor. The possible role of TATE as a prognostic factor in OSCC was investigated with respect to tumor differentiation; perineural, vascular, and muscular invasion (histopathologic parameters); and locoregional metastasis (clinical parameter). Tumor-associated tissue eosinophilia was low in most cases in 3 different areas. The mean eosinophil count was higher in the invasive front of tumor than intratumoral stroma and stroma subjacent the surface epithelium. The relations between TATE and tumor differentiation; perineural, vascular, and muscular invasion; and locoregional metastasis were not statistically significant (P > 0.05). Tumor-associated tissue eosinophilia has no correlation with prognostic parameters in OSCC.

Abstract
OBJECTIVE The aim was to study the utility of color Doppler ultrasound (CDUS) in diagnosis of cervical lymphadenopathy in oral cancer patients. STUDY DESIGN In a prospective study, 70 cervical lymph nodes in 30 known primary oral cancer patients were evaluated with CDUS during a period of 8 months. The intranodal perfusion sites and vascular resistance were the key CDUS features used to differentiate between reactive and metastatic cervical lymph nodes. Histopathologic confirmations were obtained by excisional biopsy of the lymph nodes. The results of preoperative clinical palpation of cervical lymph nodes and CDUS evaluation were compared with histopathologic outcome. RESULTS Clinical evaluation suspected 61 cervical lymph nodes to be malignant. According to the CDUS, out of 70 nodes, 49 lymph nodes showed features of benign lymphadenopathy and 21 lymph nodes showed features of malignant lymphadenopathy, whereas histopathologic evaluations were in favor of reactive for 57 (81.42%) and for malignant lymphadenopathy in 13 (18.57%). CONCLUSION The CDUS evaluation was found to be highly significant with a sensitivity of 92.90% and a specificity of 84.21%, after comparing the CDUS findings with histopathologic findings.

Abstract
Advanced glycation endproducts (AGEs) and their receptors, receptor for advanced glycation endproducts (RAGE), are novel groups of molecules with roles in inflammation, cytokine activation, and promotion of cell growth. Recently, RAGE has been implicated in the progression and metastasis of several epithelial tumors. The expression of RAGE was examined in 38 oral squamous cell carcinoma (OSCC) cases by immunohistochemistry. In the OSCCs, RAGE positivity, interpreted as more than 25% positive cells, was detected in 10 of 10 well-differentiated, 3 of 4 well-to-moderately differentiated, 3 of 9 moderately differentiated, 1 of 7 moderate-to-poorly differentiated, and 0 of 8 poorly differentiated tumors. The staining percentage was significantly higher in well-differentiated tumors compared to moderately (P < .05) and poorly differentiated (P < .05) tumors. All normal mucosa samples were RAGE-positive. Western blot analysis for RAGE was performed on 2 OSCCs and 2 normal oral mucosa samples. Higher expression was observed in the normal tissues compared to the OSCCs. Our results show that RAGE immunoreactivity correlates with histologic differentiation in OSCC.

Abstract
The formation and progression of head and neck squamous cell carcinoma (HNSCC) is multisystemic and involves the immune system, vascularization, and dissemination. Immune involvement includes the subversion of anti-tumor defenses. Vascularization involves both angiogenesis and vasculogenesis. Dissemination involves local tumor invasion as well as distant metastasis through processes including angiogenesis and lymphangiogenesis. Current studies in the dysregulation of various processes, including genetic stability, angiogenesis, lymphangiogenesis, immune regulation, and immune function, are opening opportunities for the development of targeted tumor therapies. The interrelationship of these processes in HNSCC development will be explored in this review.

Abstract
Squamous cell carcinomas of the upper aerodigestive tract are a global health-political challenge. Accordingly, current research efforts are aimed towards the opportunities for early recognition of risk patients, and at the recognition of risk factors related to carcinogenesis. We determined the revertant number of the variety Salmonella typhimurium TA 98 and TA 100 after incubation, with saliva samples from 100 probands as a measure of a genotoxic environment within the oral cavity, depending on the dental status as measure of oral health. Beside chronic alcohol (p=0.032) and tobacco consumption (p<0.001), the dental status displayed in partial aspects (high plaque index, high number of decayed teeth, prosthetically not rehabilitated status, p <or= 0.050) a significant connection with the genotoxic salivary activity. The periodontal status and the type of restorative filling material, as well as dental prostheses, however, had no important influence on the revertant number (p >or= 0.104). Therefore, it can be concluded that the polymicrobial supragingival plaque, as a possible independent factor, possesses a relevant mutagenic interaction with saliva, and that individual oral health is a co-factor in the development of carcinomas in the oral cavity.

Abstract
The significance of metastatic disease in the lymph nodes of the neck as a critical independent prognostic factor in head and neck cancer has long been appreciated. Although 19th century surgeons attempted to remove involved cervical lymph nodes at the time of resection of the primary cancer, a systematic approach to en bloc removal of cervical lymph node disease, described in detail by Jawdyński in 1888 and popularized and illustrated by Crile in the early 20th century, provided consistent and more effective treatment, and forms the basis of our current techniques. During the first half of the 20th century, developments included preservation of the accessory nerve in selected cases, elective neck dissection performed in association with resection of various primary tumors, bilateral neck dissection and limited neck dissection. The greatest impetus to the status of radical neck dissection came from Martin, whose technique consisted of resection of all lymph nodes from level I-V together with the accessory nerve, internal jugular vein, sternocleidomastoid muscle and various other structures in a single block of resected tissue. Martin's technical precepts were followed until the latter part of the 20th century when modifications in technique began to find general acceptance. The first description of an effective technique of modified radical neck dissection was published in Spanish by Suárez, in 1963. This technique, which preserves important structures, such as the internal jugular vein, sternocleidomastoid muscle and accessory nerve, was refined and popularized by various authors who published their results in the English language literature during the period from 1964 through 1990 and beyond. Modified or "functional" neck dissection avoids much of the morbidity of radical neck dissection while achieving equivalent degrees of control of regional disease in properly selected cases. By the late 20th century, the concept of selective neck dissection, consisting of resection of only the nodal groups at greatest risk for metastasis from a given primary site, was studied and developed. These limited dissections are now widely employed for elective, and in properly selected cases, therapeutic treatment and staging of the neck, and have been proposed for limited cervical recurrences after various chemoradiation protocols. Prospective studies have demonstrated similar rates of neck recurrence and survival after elective selective neck dissection compared to elective modified radical neck dissection. Other modifications and factors applied to treatment of cervical lymph node disease include the use of adjuvant and neo-adjuvant radiation and chemotherapy, a revised system for classification of neck dissections, the identification of various adverse prognostic factors such as extracapsular spread and extranodal soft tissue deposits, application of sentinel lymph node biopsy to staging of the neck, the use of immunohistochemical and molecular techniques for identification of lymph node metastases not detectable by light microscopy, and the possibility of endoscopic neck dissection. The authors conclude that neck dissection, as evolved over the past century, is a fundamental tool in management of patients with head and neck cancer, but is still a work in progress.

Abstract
Oral squamous cell carcinoma has a remarkable incidence worldwide and a fairly onerous prognosis, encouraging further research on factors that might modify disease outcome. In this review article, the authors approach the factors that may exert influence on the prognosis and eventually guide the selection of patients for more aggressive therapies. Published scientific data was collected, selected, and grouped into 3 main clusters: patient-, tumor-, and treatment-related factors. Well established aspects are discussed, but also those less common or with only supposed usefulness. Disease staging, extracapsular dissemination, resection margin free of disease, and tumor thickness are factors with high influence on the prognosis. There has been an increasing interest in the study of tumor molecular factors, and some have been strongly correlated with the outcome, showing promising pathways for the future development of more effective prognosis systems and anticancer therapies.

Abstract
Selective neck dissection is a modification of the more comprehensive modified radical or radical neck dissection that is designed to remove only those nodal levels considered to be at risk for harboring nodal metastases. The role of selective neck dissection continues to evolve: while initially designed as a staging and diagnostic procedure for patients without clinical evidence of nodal disease, a growing body of literature suggests that selective neck dissection has a therapeutic role in patients with clinical and histologic evidence of nodal metastases. The rationale behind selective neck dissection, its application in the clinically negative but histologically node-positive neck and the extended application of selective neck dissection in patients with clinical evidence of nodal disease are discussed.

Abstract
The aim was to evaluate E-cadherin expression in oral squamous cell carcinoma, and its possible relationships with tumour histology and with clinical course and survival. Surgical biopsies from 47 cases of oral squamous cell carcinoma were analysed for expression of E-cadherin using immunohistochemistry. Statistical analyses were performed to identify possible associations with tumour clinic-histological features and with clinical course and survival. Weak or absent E-cadherin expression was associated with a more invasive histological pattern and with metastasis to the cervical lymph nodes. Uni- and multivariate analyses indicated that weak or undetectable E-cadherin expression is an indicator of shorter disease-free period and shorter survival time. Reduced E-cadherin expression in oral squamous cell carcinoma is associated with more aggressive tumour behaviour and worse prognosis.

Abstract
Clinical staging of cervical lymph nodes from patients with squamous cell carcinoma of the head and neck (SCCHN) has only 50% accuracy compared with definitive pathologic assessment. Consequently, both clinically positive and clinically negative patients frequently undergo neck dissections that may not be necessary. To address this potential overtreatment, sentinel lymph node (SLN) biopsy is currently being evaluated to provide better staging of the neck. However, to fully realize the potential improvement in patient care afforded by the SLN procedure, a rapid and accurate SLN analysis is necessary. We used quantitative reverse transcription-PCR (QRT-PCR) to screen 40 potential markers for their ability to detect SCCHN metastases to cervical lymph nodes. Seven markers were identified with good characteristics for identifying metastatic disease, and these were validated using a set of 26 primary tumors, 19 histologically positive lymph nodes, and 21 benign nodes from patients without cancer. Four markers discriminated between positive and benign nodes with accuracy >97% but only one marker, pemphigus vulgaris antigen (PVA), discriminated with 100% accuracy in both the observed data and a statistical bootstrap analysis. A rapid QRT-PCR assay for PVA was then developed and incorporated into a prototype instrument capable of performing fully automated RNA isolation and QRT-PCR. The automated analysis with PVA provided perfect discrimination between histologically positive and benign lymph nodes and correctly identified two lymph nodes with micrometastatic tumor deposits. These assays were completed (from tissue to result) in approximately 30 minutes, thus demonstrating the feasibility of intraoperative staging of SCCHN SLNs by QRT-PCR.

Abstract
Angiogenesis is essential for the development and progression of malignant tumours, and there is increasing evidence that microvessel density (MVD) can be considered an indirect marker of neo-angiogenesis. However, there is still disagreement concerning the clinical relevance and prognostic significance of MVD in head and neck squamous cell carcinomas (HNSCCs). MVD was evaluated in 127 HNSCC patients by means of immunohistochemistry using monoclonal antibodies (mAbs) against CD34 and CD105 (endoglin), which has recently been described as a potent marker of neo-vascularisation in various malignancies. MVD was expressed as the mean number of vessels/mm2. The mean CD34+ and CD105+ MVD values were significantly higher in T3-T4 tumours and those in an advanced clinical stage; furthermore, CD105+ MVD was significantly higher in N+ tumours. The patients with a high CD105+ MVD had a significantly shorter disease-free and overall survival; CD34+ MVD was not associated with survival. Similarly, in the subset of lymph-node negative patients, higher CD105+ MVD values were significantly associated with either OS and DFS. Multivariate analysis showed that a high CD105+ MVD was the only independent marker of tumour recurrence or death. Our data suggest that CD105+ MVD may represent an additional prognostic factor in HNSCC patients providing more accurate data for the determination of prognosis and management in the subset of lymph node negative patients.

Abstract
Initial cancer evaluation includes assessment of histologic appearance, tumor grading, assessment of lymph node status, and presence of metastasis. However, traditional diagnostic methods such as histopathology and radiology are not sensitive enough to detect small numbers of cancer cells and are limited in their ability to predict response to treatment. Recently, there has been considerable progress in molecular diagnostics in these areas. Using molecular-based technologies, it is now possible to detect cancer early in asymptomatic individuals, identify minimal residual disease at histopathologic normal surgical margins, more precisely assess tumor burden in cancer patients, and more accurately assess the prognosis of the patients. Examples of these applications in the evaluation of head and neck cancer are reviewed here. However, despite the great promise of these new molecular approaches for cancer detection, much of the current technology limits their implementation into routine clinical use.
