Abstract
PURPOSE In this study, we systematically investigated and analyzed articles focusing on the prognostic value of E-cadherin (E-cad) in human head and neck squamous cell carcinoma (HNSCC). METHODS Searching through the different databases, the studies examining the associations between E-cad and HNSCC prognosis were identified. Outcomes such as disease-specific survival and overall survival were considered acceptable. Hazard ratio (HR) with 95% confidence interval (CI) was used to demonstrate prognostic value. RESULTS A total of 40 studies were systematically analyzed, and finally, 1939 subjects were included in our meta-analysis. Our findings showed that significant aberrant expression of E-cad was associated with poor survival. However, some studies showed increased expression of E-cad in metastatic lesions was associated with poor prognosis. Alteration in location of E-cad expression also showed significant association with cancer survival, i.e., increased cytoplasmic E-cad. We conducted a meta-analysis on the eligible articles using a random effect model because of moderate heterogeneity. Strong association between aberrant expression of E-cad and poor survival was demonstrated (pooled HR = 2.28; 95% CI 1.78-2.91). CONCLUSIONS Aberrant expression of E-cad may be a promising prognostic signature for HNSCC, especially when it is used with other prognostic markers.

Comparison of Functional Organ Preservation by Concomitant Boost Radiotherapy Versus Concurrent Chemoradiation in Locally Advanced Carcinoma of Larynx or Hypopharynx: A Prospective Randomized Study. Indian J Otolaryngol Head Neck Surg 2019; 71:360-366. [PMID: 31559204 DOI: 10.1007/s12070-019-01604-2] [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: 09/25/2018] [Accepted: 01/22/2019] [Indexed: 10/27/2022] Open
Abstract
Functional organ preservation is a major challenge in management of advanced laryngeal and hypopharyngeal carcinoma. Although ideal approach is a subject of much debate, radiotherapy with or without chemotherapy is most commonly used modality. This randomized study was conducted to compare functional organ preservation by chemoradiation (CRT) versus concomitant boost radiotherapy (CBRT). A total of 40 patients with advanced (stage III/stage IVa) laryngeal and hypopharyngeal cancer were randomized to receive either CRT (n = 20) to a dose of 66 Gy in 33 fractions over 6.5 weeks with concurrent cisplatin (100 mg/m2 on days 1, 22 and 43) or CBRT (n = 20) to a dose of 67.5 Gy in 40 fractions over 5 weeks. Patients were assessed for organ preservation rate, toxicities, voice and swallowing functions utilizing Voice Related Quality of Life (VRQOL) and MD Anderson Dysphagia Inventory (MDADI) scores, respectively, for minimum follow up of 6 months. Organ preservation rate (intact disease free larynx) at 6 months post treatment was observed in 100% in CRT arm and 95% in CBRT arm. There was no significant difference in mucositis and dermatitis in two arms (p = 0.82 and 0.78, respectively). Dysphagia was observed more in CRT arm (n = 12 vs n = 6). Late toxicities grade 3 xerostomia, grade 2 dysguesia, were seen significantly more in CRT arm. There was no statistical difference between the two arms in terms of VRQOL (p = 0.55) and MDADI scores (p = 0.13). In CRT arm 13 patients complete response and in CBRT arm 12 patients had complete response. Accelerated fractionation with concomitant boost schedule is as effective as CRT in anatomical and functional preservation of larynx. The toxicities, voice and dysphagia related quality of life is comparable.

Abstract
S-Adenosyl-l-methionine (AdoMet) is a naturally and widely occurring sulfonium compound that plays a primary role in cell metabolism and acts as the principal methyl donor in many methylation reactions. AdoMet also exhibits antiproliferative and proapoptotic activities in different cancer cells. However, the molecular mechanisms underlying the effects exerted by AdoMet have only been partially studied. In the current study, we evaluated the antiproliferative effect of AdoMet on Cal-33 oral and JHU-SCC-011 laryngeal squamous cancer cells to define the underlying mechanisms. We demonstrated that AdoMet induced apoptosis in Cal-33 and JHU-SCC-011 cells, involving a caspase-dependent mechanism paralleled by an increased Bax/Bcl-2 ratio. Moreover, we showed, for the first time, that AdoMet induced ER-stress in Cal-33 cells and activated the unfolded protein response, which can be responsible for apoptosis induction through the activation of CHOP and JNK. In addition, AdoMet-induced ER-stress was followed by autophagy with a consistent increase in the levels of the autophagic marker LC3B-II, which was indeed potentiated by the autophago-lysosome inhibitor chloroquine. As both escape from apoptosis and decreased activation of JNK are mechanisms of resistance to cisplatin (cDPP), an agent usually used in cancer therapy, we have evaluated the effects of AdoMet in combination with cDPP on Cal-33 cells. Our data showed that the combined treatment resulted in a strong synergism in inhibiting cell proliferation and in enhancing apoptosis via intrinsic mechanism. These results demonstrate that AdoMet has ER-stress-mediated antiproliferative activity and synergizes with cDDP on cell growth inhibition, thus providing the basis for its use in new anticancer strategies.

MicroRNA-Related Genetic Variants Associated with Survival of Head and Neck Squamous Cell Carcinoma. Cancer Epidemiol Biomarkers Prev 2018; 28:127-136. [PMID: 29880533 DOI: 10.1158/1055-9965.epi-18-0002] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2018] [Revised: 03/23/2018] [Accepted: 06/04/2018] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Head and neck squamous cell carcinoma (HNSCC) is commonly diagnosed at an advanced stage, and prognosis for such patients is poor. There remains a gap in our understanding of genetic variants related with HNSCC prognosis. miRNA-related single nucleotide polymorphisms (miR-SNPs) are a class of genetic variants with gene-regulatory potential. METHODS We used a genome-scale approach and independent patient populations in a two-stage approach to test 40,286 common miR-SNPs for association with HNSCC survival in the discovery population (n = 847), and selected the strongest associations for replication in validation phase cases (n = 1,236). Furthermore, we leveraged miRNA interaction databases and miRNA expression data from The Cancer Genome Atlas, to provide functional insight for the identified and replicated associations. RESULTS Joint population analyses identified novel miR-SNPs associated with overall survival in oral and laryngeal cancers. rs1816158, located within long noncoding RNA MIR100HG, was associated with overall survival in oral cavity cancer (HR, 1.56; 95% confidence interval (CI), 1.21-2.00). In addition, expression of MIR100HG-embedded miRNA, miR-100, was significantly associated with overall survival in an independent cohort of HNSCC cases (HR, 1.25; 95% CI, 1.06-1.49). A SNP in the 3'UTR of SH3BP4 (rs56161233) that overlaps predicted miRNA-binding sites and is predicted to disrupt several miRNA-mRNA interactions was associated with overall survival of laryngeal cancer (HR, 2.57; 95% CI, 1.71-3.86). CONCLUSIONS This work reveals novel miR-SNPs associated with HNSCC survival, and utilizes miRNA-mRNA interaction and expression data to provide functional support for these associations. IMPACT These findings extend our understanding of how genetic variation contributes to HNSCC survival, and may contribute to future prognostic models for improved risk stratification.

Abstract
Background: Head and Neck Squamous Cell Carcinomas (HNSCC) is the sixth most common cancer globally. In India, on an average 25-30% of all cancer cases affect the head and neck. The etiological factors associated with HNSCC are tobacco, alcohol and environmental carcinogens. However there are few cases, where there are no obvious risk factors involved. In western counties, there are many reports of human papilloma virus (HPV) association with HNSCC. Hence, we conducted a study to determine the role of HPV infection and risk factors among patients with HNSCC. Materials and Methods: A prospective, cross-sectional study was conducted in a tertiary referral centre from January 2014 to March 2016. 88 patients were enrolled in the study. Socio- demographic, behavioural data, site and subsite involvement, histopathology, staging and treatment were documented. Polymerase chain reaction (PCR) was performed to detect the presence of HPV DNA using consensus primers MY 09/11 and GP5+/GP6+ and further the samples were subjected to PCR for detecting HPV type 16 and 18. Results: The study included 88 participants with HNSCC. 57 had oral and oropharyngeal squamous cell carcinoma, 11 with laryngeal malignancy and 20 involving hypopharynx. Among the participants buccal mucosa (n=22) was the most common subsite involved, majority (50%) had moderately differentiated squamous cell carcinoma and 53.4% presented in stage IV. 2 (2.6%) cases were positive for HPV consensus and both were positive for HPV 16, one case each in larynx and hypopharynx. There was statistical significance in the association between betel nut chewing, cigarette smoking and alcohol intake as risk factors in the carcinogenesis of HNSCC. Conclusion: In our setting in South India, HPV does not play a major role in the carcinogenesis of HNSCC but betel nut chewing, tobacco exposure and alcohol consumption remain major risk factors for HNSCC.

Abstract
C-reactive protein (CRP) acts as a biomarker reflecting different degrees of inflammation. Accumulating reports have suggested that there is a close relationship between CRP and various cancers. However, the influence of CRP on the development of tongue squamous cell carcinoma (TSCC) remains unclear. The purpose of this study was to investigate the role of CRP in TSCC. The results of immunohistochemical staining and statistical analyses showed that CRP expression was associated with TSCC tumor size, lymph node metastasis and pathological differentiation. Cell Counting Kit-8 (CCK-8) assay revealed that CRP could enhance TSCC cell proliferation in a dose- and time-dependent manner. Moreover, with CRP stimulation, proliferating cell nuclear antigen (PCNA) expression patterns presented a notable time-dependent up-regulation. In addition, CRP could enhance the invasion and migration of TSCC cells, as revealed by transwell and wound-healing assays, respectively. Annexin V-FITC/PI staining showed that CRP could protect TSCC cells from starvation- and drug-induced apoptosis. With CRP stimulation, the protein expression levels of phosphorylated protein kinase B (pAkt), phosphorylated mammalian target of rapamycin (pmTOR) and phosphorylated S6 ribosomal protein (pS6) were significantly increased, as demonstrated by western blot analysis. Our data suggest that CRP may play an important role in the development of TSCC. Moreover, the biological effects of CRP on TSCC cells might be related to Akt, mTOR, and S6.

Abstract
Metformin is a biguanide widely prescribed as an antidiabetic drug for type 2 diabetes mellitus patients. The purpose of the present study was to observe the effects of the new metformin derivative, HL156A, on human oral cancer cell and to investigate its possible mechanisms. It was observed that HL156A significantly decreased FaDu and YD‐10B cell viability and colony formation in a dose‐dependent way. HL156A also markedly reduced wound closure and migration of FaDu and YD‐10B cells. We observed that HL156A decreased mitochondrial membrane potential and induced reactive oxygen species (ROS) levels and apoptotic cells with caspase‐3 and ‐9 activation. HL156A inhibited the expression and activation of insulin‐like growth factor (IGF)‐1 and its downstream proteins, AKT, mammalian target of rapamycin (mTOR), and ERK1/2. In addition, HL156A activated AMP‐activated protein kinase/nuclear factor kappa B (AMPK‐NF‐κB) signaling of FaDu and YD‐10B cells. A xenograft mouse model further showed that HL156A suppressed AT84 mouse oral tumor growth, accompanied by down‐regulated p‐IGF‐1, p‐mTOR, proliferating cell nuclear antigen (PCNA) and promoted p‐AMPK and TUNEL expression. These results suggest the potential value of the new metformin derivative HL156A as a candidate for a therapeutic modality for the treatment of oral cancer.

Abstract
Oral squamous cell carcinoma (OSCC) is the sixth most common type cancer worldwide, with poor prognosis. The present study aimed to identify gene signatures that could classify OSCC and predict prognosis in different stages. A training data set (GSE41613) and two validation data sets (GSE42743 and GSE26549) were acquired from the online Gene Expression Omnibus database. In the training data set, patients were classified based on the tumor‑node‑metastasis staging system, and subsequently grouped into low stage (L) or high stage (H). Signature genes between L and H stages were selected by disparity index analysis, and classification was performed by the expression of these signature genes. The established classification was compared with the L and H classification, and fivefold cross validation was used to evaluate the stability. Enrichment analysis for the signature genes was implemented by the Database for Annotation, Visualization and Integration Discovery. Two validation data sets were used to determine the precise of classification. Survival analysis was conducted followed each classification using the package 'survival' in R software. A set of 24 signature genes was identified based on the classification model with the Fi value of 0.47, which was used to distinguish OSCC samples in two different stages. Overall survival of patients in the H stage was higher than those in the L stage. Signature genes were primarily enriched in 'ether lipid metabolism' pathway and biological processes such as 'positive regulation of adaptive immune response' and 'apoptotic cell clearance'. The results provided a novel 24‑gene set that may be used as biomarkers to predict OSCC prognosis with high accuracy, which may be used to determine an appropriate treatment program for patients with OSCC in addition to the traditional evaluation index.

Abstract
Head and neck squamous cell carcinoma (HNSCC) is often diagnosed at advanced stages, incurring significant high mortality and morbidity. This review explored the risk stratification of miRNAs, and investigated the impact of miRNA networking in HNSCC prognostication. We performed a meta-analysis and a systematic literature search on online databases for papers published prior to December 1, 2016. The list of miRNAs was uploaded to MetacoreTM to construct a protein-protein interaction network, which was used to identify targets of the miRNAs and potential drugs. In addition, a representative network was further validated by immunohistochemistry in a cohort of 100 patients. We found 116 studies that included 8,194 subjects, in which the relationship between miRNA expression and prognosis of HNSCC were analyzed. Significant elevated expressions of 27 miRNAs and decreased expression of 26 miRNAs were associated with poor outcome. After excluding the studies causing heterogeneity, a fixed model was applied, which showed a statistically significant association between increased expression of miR-21 and poor survival (Pooled HR = 1.81,95% CI = 0.66-2.95, P < 0.005). We identified four networks affected by the miRNAs expression and enriched in genes related to metabolic processes and regulation of cell mitogenesis in response to extracellular stimuli. One network point out to 16 miRNAs directly or indirectly involved in the regulation of androgen-receptor (AR). Evaluation of AR protein expression in our cohort revealed that patients with upregulation of AR had poor survival rates (log-rank test, P < 0.005). This study showed that miRNAs have potential prognostic value to serve as screening tool for HNSCC during the follow-up. In addition, the implementation of a network-based analysis may reveal proteins with potential to be used as a biomarker.

Abstract
Oral cancer is among the most prevalent cancers in the world. Moreover, it is one of the major health problems and causes of death in many regions of the world. The traditional treatment modalities include surgical removal, radiation therapy, systemic chemotherapy, or a combination of these methods. In recent decades, there has been significant interest in intraoral site-specific chemoprevention via local drug delivery using polymeric systems. Because of its easy accessibility and clear visibility, the oral mucosa is amenable for local drug delivery. A variety of polymeric systems-such as gels, tablets, films, patches, injectable systems (e.g., millicylindrical implants, microparticles, and in situ-forming depots), and nanosized carriers (e.g., polymeric nanoparticles, nanofibers, polymer-drug conjugates, polymeric micelles, nanoliposomes, nanoemulsions, and polymersomes)-have been developed and evaluated for the local delivery of natural and synthetic chemopreventive agents. The findings of in vitro, ex vivo, and in vivo studies and the positive outcome of clinical trials demonstrate that intraoral site-specific drug delivery is an attractive, highly effective and patient-friendly strategy for the management of oral cancer. Intraoral site-specific drug delivery provides unique therapeutic advantages when compared to systemic chemotherapy. Moreover, intraoral drug delivery systems are self-administrable and can be removed when needed, increasing patient compliance. This article covers important aspects and advances related to the design, development, and efficacy of polymeric systems for intraoral site-specific drug delivery. © 2017 Wiley Periodicals, Inc.

Abstract
PURPOSE The Australian healthcare system has invested heavily in multidisciplinary cancer care teams. Despite such investments, guidelines that clearly delineate standard of care dysphagia treatment are lacking and services provided to Head and Neck Cancer (HNC) patients are not always consistent. There is little consensus regarding the frequency and intensity of dysphagia therapy. This is largely due to a lack of well-designed clinical trials that establish the efficacy of any dysphagia therapy in this patient population. The aim of this study was to evaluate HNC dysphagia therapy patterns among Australian speech-language pathologists (SLPs). METHOD A 22 question internet-based survey was administered to a web-based professional interest group. Results were analysed by institution type and individual clinical experience. RESULT A response rate of 46% was achieved (67 out of 144 surveyed). This survey identified several aspects of dysphagia management that were provided uniformly in addition to many aspects of care that showed a lack of consensus. CONCLUSION By comparing the results of this survey with existing international best-evidence treatment guidelines, the development of uniform Australian guidelines may be facilitated. However, more authoritative data on dysphagia treatment efficacy is needed to provide uniform evidence-based HNC dysphagia treatment guidelines.

Abstract
BACKGROUND Vascular endothelial growth factor (VEGF) plays an important role in the formation of capillary blood vessels. The purpose of this study was to evaluate the inhibitory effect of VEGF-targeted paclitaxel (PTX)-loaded liposome microbubbles (VTPLLMs) on the proliferation of human epidermoid (Hep-2) laryngeal squamous cell carcinoma (SCC). METHODS Six groups were randomly divided. The inhibitory effects on Hep-2 proliferation were assessed by a methylthiazol tetrazolium (MTT) method. The cell cycle distributions were investigated by flow cytometry. The expression variations of VEGF and caspase-3 were compared by Western blotting. RESULTS Proliferation of Hep-2 in the VTPLLM+ultrasound group was significantly inhibited, and flow cytometry showed that the Hep-2 cells were significantly blocked at stage G2/M compared with other groups. Moreover, Western blotting showed VEGF expression was downregulated and caspase-3 expression was upregulated. CONCLUSION VTPLLMs can efficiently inhibit tumor cell proliferation and outperform nontargeted microbubbles or PTX. © 2017 Wiley Periodicals, Inc. Head Neck 39: 656-661, 2017.

Abstract
Despite advances in therapy, survival among patients with locally advanced squamous cell carcinoma of tongue (TSCC) and cervical lymph node metastasis remains dismal. Here, we estimated the functional effect of AEG-1 on TSCC metastasis and explored the molecular mechanism by which AEG-1 stimulates epithelial-mesenchymal transition (EMT). We initially found that AEG-1 mRNA levels were much higher in metastatic TSCC than in non-metastatic TSCC and that AEG-1 expression strongly correlates with EMT status. Receiver operating characteristic analysis showed that the combined AEG-1 and EMT statuses are predictive of the survival rate among TSCC patients. In addition, AEG-1 knockdown inhibited EMT in cultured TSCC cell lines and in a xenograft-mouse model. Recombinant AEG-1 activated Wnt/PCP-Rho signaling, and its stimulatory effects on TSCC cell invasiveness and EMT were reversed by an anti-Wnt5a neutralizing antibody or by inhibition of Rac1 or ROCK. These results highlight the critical stimulatory effect of AEG-1 on cancer cell invasiveness and EMT and indicate that AEG-1 may be a useful prognostic biomarker for TSCC patients.

Antitumor activity of 7RH, a discoidin domain receptor 1 inhibitor, alone or in combination with dasatinib exhibits antitumor effects in nasopharyngeal carcinoma cells. Oncol Lett 2016; 12:3598-3608. [PMID: 27900042 DOI: 10.3892/ol.2016.5088] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2015] [Accepted: 07/26/2016] [Indexed: 12/28/2022] Open
Abstract
Dysregulation of the discoidin domain receptors (DDRs) has been implicated in the development of numerous types of tumors, including head and neck cancer, and nasopharyngeal, breast, ovarian and esophageal carcinomas. Furthermore, agents that inhibit DDR1 activity are hypothesized to be useful for the treatment of nasopharyngeal carcinoma (NPC). The aim of the present study was to evaluate the effect of the DDR1 inhibitory (3-(2-(pyrazolo(1,5-a)pyrimidin-6-yl)-ethynyl)benzamide compound, 7RH, in NPC cells both in vitro and in vivo, and its effect when used in combination with dasatinib, a SRC family kinase (SFK) inhibitor. The effects of 7RH alone or in combination with dasatinib on cell viability were assessed using MTT assays and apoptosis was detected by flow cytometry. In addition, western blotting was performed to analyze the relative protein expression levels of cell cycle-associated genes in human NPC cell lines (CNE1, CNE2, HONE1 and SUNE1). Cell migration was also assessed using cell adhesion assays. Furthermore, tumor xenografts of CNE2 NPC cells were established in nude mice and the growth inhibitory effects of 7RH treatment alone or in combination with dasatinib were evaluated. Finally, knockdown of DDR1 protein expression was achieved by transfection of CNE2 cells with DDR1-specific small interfering RNA. Treatment with 7RH effectively suppressed the proliferation and induced the apoptosis of NPC cells. In addition, the Janus kinase 1 (JAK1)/signal transducer and activator of transcription (STAT3) signaling pathway was downregulated by 7RH, whereas the activities of the Ras/Raf/mitogen-activated protein kinase kinase (MEK)/extracellular signal-regulated kinase (ERK) and phosphoinositide 3-kinase (PI3K)/AKT signaling pathways were upregulated in response to 7RH treatment. Furthermore, the expression levels of phosphorylated SRC were increased in NPC cells treated with 7RH; thus indicating that SRC exhibits a vital function in the resistance of NPC cells to 7RH via activation of the PI3K/AKT signaling pathway. The results of the present study indicate that DDR1 and SFK inhibition may present a potential therapeutic strategy for patients with NPC.

Abstract
Background Nasopharyngeal carcinoma (NPC) is a common malignancy in South-East Asia. NPC is characterized by distant metastasis and poor prognosis. The pathophysiological mechanism of nasopharyngeal carcinoma is unknown. This study aimed to identify the crucial miRNAs in nasopharyngeal carcinoma and their target genes, and to discover the potential mechanism of nasopharyngeal carcinoma development. Material/Methods Microarray expression profiling of miRNA and mRNA from the Gene Expression Omnibus database was downloaded, and we performed a significance analysis of differential expression. An interaction network of miRNAs and target genes was constructed. The underlying function of differentially expressed genes was predicted through Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses. To validate the microarray analysis data, significantly different expression levels of miRNAs and target genes were validated by quantitative real-time polymerase chain reaction. Results We identified 27 differentially expressed miRNAs and 982 differentially expressed mRNAs between NPC and normal control tissues. 12 miRNAs and 547 mRNAs were up-regulated and 15 miRNAs and 435 mRNAs were down-regulated in NPC samples. We found a total of 1185 negative correlation pairs between miRNA and mRNA. Differentially expressed target genes were significantly enriched in pathways in cancer, cell cycle, and cytokine-cytokine receptor interaction signaling pathways. Significantly differentially expressed miRNAs and genes, such as hsa-miR-205, hsa-miR-18b, hsa-miR-632, hsa-miR-130a, hsa-miR-34b, PIGR, SMPD3, CD22, DTX4, and CDC6, may play essential roles in the development of nasopharyngeal carcinoma. Conclusions hsa-miR-205, hsa-miR-18b, hsa-miR-632, hsa-miR-130a, and hsa-miR-34b may be related to the development of nasopharyngeal carcinoma by regulating the genes involved in pathways in cancer and cell cycle signaling pathways.

Abstract
Mitogen-activated protein kinases (MAPKs) are a family of protein kinases that link extracellular stimuli with intracellular responses and participate in numerous cellular processes such as growth, proliferation, differentiation, inflammation and apoptosis. Persistent activation of signal transducer and activator of transcription 3 (STAT3), which is accompanied by increases in STAT3 tyrosine phosphorylation, is associated with cell proliferation, differentiation and apoptosis in oral squamous cell carcinoma (OSCC). The role and significance of the activation of MAPKs, particularly of c-Jun N-terminal kinase (JNK), on STAT3 signaling in OSCC have not been thoroughly investigated. The present study examines the effects of JNK1/2 modulation on STAT3 signaling and cellular activities in OSCC cells. The expression levels of STAT3 [total, tyrosine phosphorylated (p-Tyr) and serine phosphorylated (p-Ser)], JNK, c-Jun and cyclin D1 were assessed in the OSCC cell lines SCC25 and SCC9. Inhibition of JNK1/2 was achieved by pharmacological agents (SP600125) and by small interfering RNA (siRNA) silencing, while JNK1/2 was induced by active MAPK kinase 7. Cell proliferation and viability rates were also evaluated. Inhibition of JNK1/2 with either SP600125 treatment or specific siRNA silencing resulted in decreased levels of p-Ser STAT3 and increased levels of p-Tyr STAT3 and cyclin D1 in both cell lines. Furthermore, JNK1/2 inhibition resulted in a dose-dependent increase in cell growth and viability in both cell lines. Opposite results were observed with JNK1/2 induction in both cell lines. The present results are supportive of a potential tumor suppressive role of JNK1/2 signaling in OSCC, which may be mediated through negative crosstalk with the oncogenic STAT3 signaling pathway. The possible therapeutic implications of JNK1/2 inhibition for patients with OSCC require to be investigated.

Abstract
CD3ζ has emerged as a clinically important immunological marker in head and neck squamous cell carcinoma (HNSCC) with reduced level of expression reported in both tumor infiltrating lymphocytes and peripheral blood lymphocytes. In this prospective study (power = 0.99, α = 0.05), CD3ζ expression was compared in 47 HNSCC patients and 53 controls using standardized flow cytometric method. There was no statistical difference in the percentages of the CD3 ε+ T-cell subset present in the peripheral blood mononuclear cells of the HNSCC patients and the healthy controls; however, T cells from the HNSCC patients produced a significantly weaker IFN-γ response in comparison to the healthy controls, when they were stimulated by the recall viral CEF peptide antigen. All patients were followed up for at least 3 years with a median follow-up of 45 months. Levels of CD3ζ-chain expression were measured at 117 follow-up visits at six-month intervals. Receiver operating characteristic curve identified the optimal cut off as a 12% increase in post treatment CD3ζ-chain expression from the baseline levels to confirm absence of HNSCC with the area under curve of 0.81 (95% CI = 0.68-0.94) for predicting absence of HNSCC. The specificity, sensitivity and positive predictive value were 81.25% 79.21% and 97.56%, respectively. Three-year disease specific survival (DSS) was significantly lower (p = 0.007) at 63.2% for patients who showed <12% increase in CD3ζ-chain level as compared to 96.2% for patients who had ≥12% increase. Our results indicate that the change in CD3ζ-chain expression from the baseline is an independent predictor of residual and recurrent HNSCC.

Abstract
OBJECTIVES The aim of this study is to analyze the survival benefits of surgery and/or radiation therapy over no therapy in patients with metastatic (M1) squamous cell carcinoma of the head and neck region (HN-SCC). STUDY DESIGN Retrospective administrative database analysis. SUBJECTS AND METHODS The Surveillance, Epidemiology, and End Results (SEER) database was queried for M1 HN-SCC cases from 1988 to 2012 (6663 patients). Patient demographics, initial treatment, and survival outcomes were analyzed. Survival was analyzed with the Kaplan-Meier model. RESULTS Of the 6663 patients identified with M1 HN-SCC in the SEER database, 1669 patients received no therapy; 2459 patients, radiotherapy; 570 patients, surgery; and 1100 patients, surgery with adjuvant radiotherapy. The mean survival was 8.44 months for patients who did not undergo any therapy. In comparison, patients who underwent radiotherapy alone, surgery alone, or surgery with radiotherapy had mean survivals of 18.03 (P < .0001), 31.07 (P < .0001), and 39.93 (P < .0001) months, respectively. The 5-year disease-specific survival rates were 6.35% for no therapy, 17.51% for radiotherapy alone, 30.50% for surgery alone, and 33.75% for surgery with radiotherapy (P < .0001). Site-specific analysis revealed that surgery and/or radiation provides disease-specific survival benefit as compared with no therapy at all subsites within the head and neck region. CONCLUSIONS Surgery and/or radiation-which has been shown to improve quality of life in patients with advanced cancer-is associated with an increased survival when utilized in patients with distant metastatic disease.

Abstract
BACKGROUND TGFβ1 and Smad3 play an important role in the process of EMT. TGFβ1 regulates the expression of Jagged1 by modulating Notch signaling. Jagged1 is related to tumor invasion, metastasis, chemotherapy resistance, and tumor immune escape. The aims of this study are to examine deregulation of TGFβ1-Smad3-Jagged1-Notch1-Slug signaling in TSCC and to investigate its roles in TSCC progression. MATERIALS AND METHODS Notch1, Smad3, Jagged1 and Slug proteins and mRNA expression were detected in specimens from 89 cases of patients. We analyzed the correlation between their expressions and histological grade, clinical stage and lymph node metastasis. RESULTS Notch1, Smad3, Jagged1 and Slug mRNA expressions in TSCC were higher than normal tissue (P <0.05). The protein expression of Notch1 and Smad3 in TSCC were higher (χ(2) =7.30, P <0.01 and χ(2) = 5.84, P <0.05). Notch1 and Smad3 expressions were correlated with clinical stage (χ(2) =18.81, P<0.01; χ(2) =22.29, P<0.01), but not Jagged1 (χ(2) =0.53, P>0.05). The Slug protein expression was correlated with clinical stage. The positive rate of Notch1 was higher in lymph node metastases positive cases (χ(2) =7.30, P<0.01). Moreover, higher expression of Jagged1 was found in lymph node positive cases (χ(2) =10.82, P<0.01). CONCLUSIONS The key protein expression in TGFβ1-Smad3-Jagged1-Notch1-Slug signaling pathway significantly correlated with the clinicopathological features of TSCC patients. It's potential as a biomarker and a novel therapeutic target for TSCC patients at risk of metastasis. It may play an irreplaceable role in TSCC progression which may attribute to promoting EMT which enhances cell migration, invasion and metastasis.

Abstract
BACKGROUND Tumor-associated macrophages (TAMs) are implicated in the growth, invasion and metastasis of various solid tumors. However, the phenotype of TAMs in premalignant lesions of solid tumors has not been clarified. In the present study, we identify the phenotype of TAMs in leukoplakia, an oral premalignant lesion, by immunohistochemical analysis and investigate the involvement of infiltrated T cells that participate in the polarization of TAMs. METHODS The subjects included 30 patients with oral leukoplakia and 10 individuals with normal mucosa. Hematoxylin and eosin slides were examined for the histological grades, and immunohistochemical analysis was carried out using antibodies against CD68 (pan-MΦ), CD80 (M1 MΦ), CD163 (M2 MΦ), CD4 (helper T cells: Th), CD8 (cytotoxic T cells), CXCR3, CCR5 (Th1), CCR4 (Th2), signal transducer and activator of transcription (STAT1), phosphorylated STAT1 (pSTAT1) and chemokine CXCL9. The differences in the numbers of positively stained cells among the different histological grades were tested for statistical significance using the Kruskal-Wallis test. Correlations between different types of immune cells were determined using Spearman's rank analysis. RESULTS An increase in the rate of CD163(+) TAM infiltration was observed in mild and moderate epithelial dysplasia, which positively correlated with the rate of intraepithelial CD4(+) Th cell infiltration. Although CCR4(+) cells rarely infiltrated, CXCR3(+) and CCR5(+) cells were observed in these lesions. Cells positive for STAT1 and chemokine CXCL9, interferon- (IFN)-induced gene products, and pSTAT1 were also observed in the same lesions. Double immunofluorescence staining demonstrated that the cells that were positive for CD163 were also positive for STAT1. CONCLUSIONS CD163(+) TAMs in oral premalignant lesions coexpress CD163 and STAT1, suggesting that the TAMs in oral premalignant lesions possess an M1 phenotype in a Th1-dominated micromilieu.

Abstract
OBJECTIVES The purpose of this study was to determine whether preoperative (18) F-FDG PET/CT is useful in assessing contralateral lymph node metastasis in the neck. DESIGN A retrospective review of medical records was performed. SETTING Patients treated at a single institute. PARTICIPANTS One hundred and fifty-seven patients whose pathology results were positive for unilateral node metastasis (N1-3) involvement and underwent preoperative (18) F-FDG PET/CT for head and neck squamous cell carcinoma (HNSCC) were reviewed. MAIN OUTCOME MEASURES Prognostic factors and nodal SUVmax were studied to identify the risk of contralateral disease. RESULTS Thirty-six (22.9%) patients had contralateral cervical lymph node metastases. The (18) F-FDG PET/CT had a sensitivity of 80% and a specificity of 96% in identifying the contralateral cervical lymph node metastases on a level-by-level basis. The median SUVmax values of the ipsilateral and contralateral lymph nodes were 3.99 ± 3.36 (range, 0-20.4) and 2.94 ± 2.04 (range, 0-8.7), respectively (P = 0.001). There was a significant difference in the median SUVmax of contralateral nodes between the benign and malignant cervical lymph nodes (2.31 ± 0.62 versus 3.28 ± 2.43, P = 0.014). The cut-off value of contralateral median SUVmax in the context of contralateral cervical metastasis was 2.5 with the sensitivity of 75% and the specificity of 94%. A median contralateral lymph node SUVmax ≥ 2.5 was associated with 5-year disease-specific survival (P = 0.038). CONCLUSION (18) F-FDG PET/CT median SUVmax cut-off values of contralateral lymph nodes ≥2.5 were associated with contralateral cervical lymph node metastases and 5-year disease-specific survival in HNSCC patients with unilateral metastases.

Abstract
Background MicroRNA-23a (miR-23a) has been demonstrated to play an important role in the development of several types of cancer, but its role in tumorigenesis of laryngeal carcinoma is still unclear. The aim of this study was to investigate the expression patterns and clinical implications of miR-23a in laryngeal cancer. Methods Quantitative RT-PCR was performed to evaluate the expression level of miR-23a in 52 pairs of laryngeal cancer. Analysis between miR-23a expression and clinical features of laryngeal carcinomas was performed by appropriate statistical methods. Role of miR-23a in laryngeal cancer cell migration and invasion was detected via transwell and matrigel assays, respectively. Results miR-23a was significantly up-regulated in laryngeal cancer tissues compared to normal adjacent laryngeal tissues (P < 0.01). Tumors with high miR-23a expression had significantly greater extent of lymph node metastasis (P < 0.01), worse clinical stage (P < 0.05) and shorter overall five-year survival (P < 0.01) than those with low miR-23a expression. Both univariate and multivariate Cox hazard regression analysis results showed that clinical stage and miR-23a expression were significantly correlated with patient five-year survival (P < 0.01). miR-23a overexpression also significantly promoted laryngeal cancer cell migration and invasion in vitro. Conclusions miR-23a, an independent prognostic factor for laryngeal cancer, participates in the onset and progression of laryngeal cancer.

The effect of prophylactic percutaneous endoscopic gastrostomy (PEG) tube placement on swallowing and swallow-related outcomes in patients undergoing radiotherapy for head and neck cancer: a systematic review. Dysphagia 2015; 30:152-75. [PMID: 25737196 DOI: 10.1007/s00455-014-9592-z] [Citation(s) in RCA: 52] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2014] [Accepted: 08/11/2014] [Indexed: 11/29/2022]
Abstract
Patients undergoing radiotherapy for head and neck cancer (HNC) often experience malnutrition and dehydration during treatment. As a result, some centres place PEG tubes prophylactically (pPEG) to prevent these negative consequences. However, recent research has suggested that pPEG use may negatively affect swallowing physiology, function and/or quality of life, especially in the long term. The purpose of this study was to systematically review the literature on pPEG use in HNC patients undergoing radiotherapy and to determine its impact on swallowing-related outcomes. The following electronic databases were searched for all relevant primary research published through February 24, 2014: AMED, CINAHL, the Cochrane Library, Embase, Healthstar, Medline, and PsycINFO. Main search terms included HNC, radiotherapy, deglutition disorders, feeding tube(s), and prophylactic or elective. References for all accepted papers were hand searched to identify additional relevant research. Methodological quality was assessed using Cochrane's Risk of Bias. At all levels, two blinded raters provided judgments. Discrepancies were resolved by consensus. The search retrieved 181 unique citations. Twenty studies met our inclusion criteria. Quality assessment revealed that all studies were at risk for bias due to non-randomized sampling and unreported or inadequate blinding. Ten studies demonstrated selection bias with significant baseline differences between pPEG patients and controls. Results regarding the frequency and severity of dysphagia and swallowing-related outcomes were varied and inconclusive. The impact of pPEG use on swallowing and swallowing-related outcomes remains unclear. Well-controlled, randomized trials are needed to determine if pPEG places patients at greater risk for developing long-term dysphagia.

Abstract
The aim of this study was to systematically review the articles investigating the prognostic value of different microRNAs (miRs) in human head and neck squamous cell carcinoma (HNSCC). Following the guidelines of the Meta-analysis of Observational Studies in Epidemiology group (MOOSE), we performed a broad and sensitive search on online databases to identify the studies that examined associations between different miRs expression and HNSCC prognosis. In this study, we considered clinical endpoints such as overall survival (OS) and disease specific survival (DFS) as acceptable outcomes. The prognostic value was demonstrated using hazard ratio (HR) with 95% confidence interval (CI). A total of 21 studies involving 1685 subjects analyzed the relationship between miRNA and prognosis of HNSCC. Our findings showed that significant elevated expressions of miR-21, miR-18a, miR-134a, miR-210, miR-181a, miR-19a, and miR-155 were associated with poor survival in human HNSCC. Conversely, decreased expressions of miR-153, miR-200c, miR-363, miR-203, miR-17, miR-205, miR-Let-7d, Let-7g, miR-34a, miR-126a, miR-375, miR-491-p5, miR 218, miR-451 and miR-125b were associated with poor prognosis. Alteration in miR-193b expression level does not show any significant association with cancer survival. We performed meta-analysis on the articles choosing miR-21 as prognostic marker. After excluding the study causing heterogeneity, a fixed model was applied, which showed an association between increased expression of miR-21 and poor survival (Pooled HR=1.57-95% CI: 1.22-2.02, P<0.05). Based on the results, it can be concluded that miRs specifically miR-21 may be promising markers for prognosis prediction in HNSCC.

Abstract
microRNAs(miRNAs) can regulate epithelial-mesenchymal transition (EMT) through transcription factors, however, little is known whether EMT transcription factors can modulate miRNAs and further induce EMT and cancer metastasis. Here we show that overexpression of Snail and Slug leads to a mesenchymal phenotype and morphology and enhances cell invasion along with stem cell properties in squamous cell carcinoma of oral tongue (OTSCC) cells. Repression of miR-101 expression by Snail and Slug is essential for Snail/Slug-induced malignant phenotypes. The suppression of miR-101 subsequently activates EZH2, the sole histone methyltransferase, inducing EMT, migration and invasion of OTSCC cells. Importantly, co-overexpression of Slug and Snail correlates with poor survival and elevated EZH2 expression in two independent patient cohorts of OTSCC specimens. These findings defined a Snail and Slug/miR-101/EZH2 pathway as a novel regulatory axis of EMT-mediated-microRNA signaling.

Abstract
INTRODUCTION: Oral cancer is a multifactorial disease of high incidence worldwide and considered a public health problem, in which prevention and early diagnosis are the best ways to reverse this situation. PURPOSE: To evaluate the level of knowledge on oral cancer in a population of dentistry students. METHOD: A questionnaire on oral cancer was applied to 150 students from six classes, divided into three groups according to their semesters. The variables studied were statistically analyzed by applying the chi-square test with confidence interval of 95% and significance level of 5%. RESULT: Eighty-eight students (60.61%) considered their level of knowledge on oral cancer good and regular, while 37.93% rated their knowledge as insufficient. Squamous cell carcinoma was listed as the most common cancer by only 38.25% of students, with the highest percentage of correct answers being observed for groups 2 (55.56%) and 3 (67.39%). The level of knowledge on the risk factors increased over the semesters; however, 77.85% considered their level of confidence to perform diagnostic procedures low. CONCLUSION: The level of knowledge on oral cancer was considered good or regular among dentistry students, and although they showed good level of knowledge on the risk factors and to specific issues of the disease, there is a clear need to implement continued educational measures throughout the course to consolidate learning on this disease.

BACKGROUND MicroRNAs (miRNAs) are known to play an important role in cancer development by post-transcriptionally affecting the expression of critical genes. The aims of this study were two-fold: (i) to develop a robust method to isolate miRNAs from small volumes of saliva and (ii) to develop a panel of saliva-based diagnostic biomarkers for the detection of head and neck squamous cell carcinoma (HNSCC). METHODS Five differentially expressed miRNAs were selected from miScript™ miRNA microarray data generated using saliva from five HNSCC patients and five healthy controls. Their differential expression was subsequently confirmed by RT-qPCR using saliva samples from healthy controls (n = 56) and HNSCC patients (n = 56). These samples were divided into two different cohorts, i.e., a first confirmatory cohort (n = 21) and a second independent validation cohort (n = 35), to narrow down the miRNA diagnostic panel to three miRNAs: miR-9, miR-134 and miR-191. This diagnostic panel was independently validated using HNSCC miRNA expression data from The Cancer Genome Atlas (TCGA), encompassing 334 tumours and 39 adjacent normal tissues. Receiver operating characteristic (ROC) curve analysis was performed to assess the diagnostic capacity of the panel. RESULTS On average 60 ng/μL miRNA was isolated from 200 μL of saliva. Overall a good correlation was observed between the microarray data and the RT-qPCR data. We found that miR-9 (P <0.0001), miR-134 (P <0.0001) and miR-191 (P <0.001) were differentially expressed between saliva from HNSCC patients and healthy controls, and that these miRNAs provided a good discriminative capacity with area under the curve (AUC) values of 0.85 (P <0.0001), 0.74 (P < 0.001) and 0.98 (P < 0.0001), respectively. In addition, we found that the salivary miRNA data showed a good correlation with the TCGA miRNA data, thereby providing an independent validation. CONCLUSIONS We show that we have developed a reliable method to isolate miRNAs from small volumes of saliva, and that the saliva-derived miRNAs miR-9, miR-134 and miR-191 may serve as novel biomarkers to reliably detect HNSCC.

Targeting the sheddase activity of ADAM17 by an anti-ADAM17 antibody D1(A12) inhibits head and neck squamous cell carcinoma cell proliferation and motility via blockage of bradykinin induced HERs transactivation. Int J Biol Sci 2014; 10:702-14.

Abstract
A disintegrin and metalloproteinase 17 (ADAM17) regulates key cellular processes including proliferation and migration through the shedding of a diverse array of substrates such as epidermal growth factor receptor (EGFR) ligands. ADAM17 is implicated in the pathogenesis of many diseases including rheumatoid arthritis and cancers such as head and neck squamous cell carcinoma (HNSCC). As a central mediator of cellular events, overexpressed EGFR is a validated molecular target in HNSCC. However, EGFR inhibition constantly leads to tumour resistance. One possible mechanism of resistance is the activation of alternative EGFR family receptors and downstream pathways via the release of their ligands. Here, we report that treating human HNSCC cells in vitro with a human anti-ADAM17 inhibitory antibody, D1(A12), suppresses proliferation and motility in the absence or presence of the EGFR tyrosine kinase inhibitor (TKI) gefitinib. Treatment with D1(A12) decreases both the endogenous and the bradykinin (BK)-stimulated shedding of HER ligands, accompanied by a reduction in the phosphorylation of HER receptors and downstream signalling pathways including STAT3, AKT and ERK. Knockdown of ADAM17, but not ADAM10, also suppresses HNSCC cell proliferation and migration. Furthermore, we show that heregulin (HRG) and heparin-binding epidermal growth factor like growth factor (HB-EGF) predominantly participate in proliferation and migration, respectively. Taken together, these results demonstrate that D1(A12)-mediated inhibition of cell proliferation, motility, phosphorylation of HER receptors and downstream signalling is achieved via reduced shedding of ADAM17 ligands. These findings underscore the importance of ADAM17 and suggest that D1(A12) might be an effective targeted agent for treating EGFR TKI-resistant HNSCC.

Abstract
BACKGROUND Membrane-bound complement restriction proteins (mCRPs) CD46, CD55 and CD59 enable tumour cells to evade complement dependent cytotoxicity and antibody-dependent killing mechanisms. But less is known about the role of these mCRPs in head and neck cancer. METHODS In this study we determined the expression of the mCRPs on head and neck squamous cell carcinoma (HNSCC) cell lines, on tumour tissue and TDLNs (tumour-draining lymph nodes) as well as on lymphocytes from HNSCC patients. The influence of the HNSCC microenvironment on the mCRP regulation was analysed using Flow Cytometry, Western blotting and small interfering RNAs (siRNA) transfection studies. RESULTS We examined the effects of the HNSCC tumour milieu on the expression levels of CD46, CD55 and CD59. We investigated the susceptibility of HNSCC cells to CDC (complement-dependent cytotoxicity) while silencing the mCRPs. Our results demonstrate a huge influence of the HNSCC tumour microenvironment on the regulation of mCRP expression and show a reciprocal regulation between the different mCRPs themselves. CONCLUSIONS In summary, our data indicate that HNSCC has evolved different strategies to evade complement attacks and that the tumour microenvironment leads to the enhancement of complement resistance of the surrounding tissue.

Abstract
Purpose. Vasculogenic mimicry (VM) was related to invasion and metastasis of head and neck squamous cell carcinoma (HNSCC) patients. This study was designed to investigate the role of EphA2 in VM formation of HNSCC. Methods. The SiRNA technique was used to knock down the expression of EphA2 in vitro. The ability of cell migration and invasion were measured by transwell and wound healing assays; three-dimensional culture was used to detect the ability of channel-like structure formation; Western blot was used to detect the expression of epithelial-mesenchymal transition- (EMT-) related molecules in vitro. Further semiquantitative real-time RT-PCR assays and immunohistochemistry were used to demonstrate expression of EphA2 and EMT-related molecules according to VM presence or not in human tissue. Results. Knocking down EphA2 in vitro leads to disabled channel-like structure formation, reduction of invasion and migration ability, and reverse of EMT-related markers. Both semiquantitative real-time RT-PCR and immunohistochemistry showed that expressions of EphA2, Twist, and Vimentin were higher in the VM-positive group than in the VM-negative group significantly, while expressions of E-cadherin, claudin4, and DSG-3 were reverse. Conclusions. EphA2 played a key role in VM formation of HNSCC through regulation of EMT.

Abstract
Oral cancer is a common malignancy associated with high morbidity and mortality. While p38 MAPK is reported to be involved in different cellular activities such as proliferation and differentiation, reports rarely define the roles of the individual members of the p38 MAPK family in cancer. We used two unique cell lines developed by our lab representing chemically induced oral cancer cells (T28) and non-tumor cells (N28) obtained from tissues surrounding the induced cancer as a model to screen out whether p38 MAPK is involved in the malignant transformation processes. The results suggest an association between p38β not p38α and oral cancer development. Additionally, the anti-cancer activity of thymoquinone (TQ) was screened out and we found evidences suggesting that the anti-tumor activity of TQ may be attributed to the downregulation of p38β MAPK.

Abstract
The retinoblastoma gene product (pRb) controls proliferation and differentiation processes in stratified epithelia. Importantly, and in contrast to other tissues, Rb deficiency does not lead to spontaneous skin tumor formation. As the cyclin-dependent kinase inhibitor p21 regulates proliferation and differentiation in the absence of pRb, we analyzed the consequences of deleting p21 in pRb-ablated stratified epithelia (hereafter pRb(ΔEpi);p21-/-). These mice display an enhancement of the phenotypic abnormalities observed in pRb(ΔEpi) animals, indicating that p21 partially compensates pRb absence. Remarkably, pRb(ΔEpi);p21-/- mice show an acute skin inflammatory phenotype and develop spontaneous epithelial tumors, particularly affecting tongue and oral tissues. Biochemical analyses and transcriptome studies reveal changes affecting multiple pathways, including DNA damage and p53-dependent signaling responses. Comparative metagenomic analyses, together with the histopathological profiles, indicate that these mice constitute a faithful model for human head and neck squamous cell carcinomas. Collectively, our findings demonstrate that p21, in conjunction with pRb, has a central role in regulating multiple epithelial processes and orchestrating specific tumor suppressor functions.

Abstract
PURPOSE To estimate whether the immunohistochemical (IHC) expression patterns of the tumor suppressor gene signal transducer and activator of transcription-1 (STAT1) and its active phosphorylated form (PSTAT1) serve as potential prognostic and predictive markers in patients with oral squamous cell carcinoma (OSCC). MATERIALS AND METHODS STAT1 and PSTAT1 protein expressions were examined immunohistochemically in OSCC tumor tissues and adjacent normal mucosa from 49 patients who underwent primary surgery. The IHC scores were correlated with all available clinicopathologic parameters that were obtained from a maximum of 7 years of follow-up, including survival and response to adjuvant therapy treatment. RESULTS There was a shift toward lower percentages of cells with STAT1 (P < .014) and PSTAT1 (P < .001) detected in OSCC tumors compared with adjacent normal tissue sites. No association with patients' clinicopathologic characteristics was shown. However, for the group of patients who received adjuvant chemotherapy, increased PSTAT1 intensity of staining in OSCC tumors was strongly associated with better overall survival (P = .008). CONCLUSIONS This is the first study to concurrently evaluate STAT1 and PSTAT1 IHC expression patterns and their prognostic significance in patients with OSCC, highlighting the potential role of PSTAT1 as a biomarker in therapeutic decision making. Large prospective studies are needed to verify these findings.

Abstract
BACKGROUND AND PURPOSE Patients treated for squamous cell carcinoma of the head and neck (HNSCC) carry a high risk of second primary malignancies (SPM). Recently, computed tomography (CT) of the chest was shown to significantly decrease the risk of death due to bronchial carcinoma (BC) in a cohort of smokers whose risk of BC is increased but might be lower than that of patients previously treated for HNSCC. Thus, the present study evaluated the potential benefit of CT and other examinations in the detection of SPM in HNSCC patients. PATIENTS AND METHODS Between July 2008 and November 2011, 118 participants underwent a prospective, systematic examination for SPM (13 women, 105 men, median age 62 years). All patients had been previously treated for HNSCC and showed no recurrence or distant metastases at the time of the study start. CT scans, ear-nose-throat endoscopy, and endoscopy of the esophagus and stomach were performed. RESULTS Overall, 33 suspicious findings were clarified by additional investigations. In all, 26 SPM were confirmed in 21 of 118 patients (18%; 10 lung, 7 HNSCC, 3 gastrointestinal, 1 renal). Eighteen of these 21 patients (86%) underwent therapy with curative intent. CONCLUSION The examinations revealed a high prevalence of curable stage SPM in HNSCC patients. Adapting a surveillance scheme including a chest CT is recommended.

Abstract
The presence of the EMT (epithelial-mesenchymal transition), EndMT (endothelial-mesenchymal transition) and VM (vasculogenic mimicry) demonstrates the multidirectional extent of phenotypic plasticity in cancers. Previous findings demonstrating the crosstalk between head and neck squamous cell carcinoma (HNSCC) and vascular endothelial growth factor (VEGF) imply that HNSCC cells share some functional commonalities with endothelial cells. Our current results reveal that cultured HNSCC cells not only possess endothelial-specific markers, but also display endotheliod functional features including low density lipoprotein uptake, formation of tube-like structures on Matrigel and growth state responsiveness to VEGF and endostatin. HNSCC cell subpopulations are also highly responsive to transforming growth factor-β1 and express its auxiliary receptor, endoglin. Furthermore, the endotheliod characteristics observed in vitro recapitulate phenotypic features observed in human HNSCC tumors. Conversely, cultured normal human oral keratinocytes and intact or ulcerated human oral epithelia do not express comparable endotheliod characteristics, which imply that assumption of endotheliod features is restricted to transformed keratinocytes. In addition, this phenotypic state reciprocity facilitates HNSCC progression by increasing production of factors that are concurrently pro-proliferative and pro-angiogenic, conserving cell energy stores by LDL internalization and enhancing cell mobility. Finally, recognition of this endotheliod phenotypic transition provides a solid rationale to evaluate the antitumorigenic potential of therapeutic agents formerly regarded as exclusively angiostatic in scope.

Abstract
PURPOSE Multidisciplinary team (MDT) care is widely accepted as best practice for patients with head and neck cancer, although there is little evidence that MDT care improves head and neck cancer related outcomes. This study aims to determine the impact of MDT care on measurable clinical quality indicators (CQIs) associated with improved patient outcomes. MATERIALS AND METHODS Patients treated for head and neck cancer at Ipswich Hospital from 2001 to 2008 were identified. Comparisons were made in adherence to CQIs between patients treated before (pre MDT) and after (post MDT) the introduction of the MDT. Associations were tested using the Chi-square and Whitney U-test. RESULTS Treatment post MDT was associated with greater adherence to CQIs than pre MDT. Post MDT had higher rates of: dental assessment (59% versus 22%, p<.0001), nutritional assessment (57% versus 39%, p=.015), PET staging (41% versus 2%, p<.0001), chemo-radiotherapy (CRT) for locally advanced disease (66% versus 16%, p<.0001) and use of adjuvant CRT for high risk disease (49% versus 16%, p<.0001). The interval between surgery and radiotherapy was shorter in the post MDT group (p=.009) as was the mean length of hospitalization (p=.002). CONCLUSIONS This study highlights the measurable advantages of MDT care over the standard, less formalized, referral process.

Abstract
The biology and clinical behavior of Head and Neck Squamous Cell Carcinomas (HNSCCs) is very distinct within different subgroups due to the distinct molecular profiles for the HPV positive versus HPV negative tumors. HPV status is the most important independent prognostic variable in multivariate analysis taking into account all other prognostic factors like tumour stage, smoking status, age and performance status. The debate today is whether the intense therapy is too aggressive in this group of patients since they show a superior survival regardless of treatment strategies. A highly divergent prognosis and distinct biology of HPV positive and HPV negative HNSCCs underlines the fact that treating them as distinct diseases is the need of the hour. Infection with HPV is associated with less aggressive disease, better loco regional control and lower rates of second primary cancers. An important caveat that remains is the emergence of intermediate prognosis of HPV positive smokers and HPV negative non smokers. Though molecular biology has provided important data on the interaction of the HPV onco proteins with genes important in cell cycle control, also speculated to be involved in pathogenesis of HNSCC, more basic research is needed to describe the differential mechanisms of tumorigenesis among the HNSCCs that show presence and absence of HPV. This is clinically relevant to reduce morbidity without compromising tumour control in HPV positive patients and improving tumour control and co-morbid illness that could be pre-existing or treatment related in HPV negative patients. There may be a need for treatment intensification and incorporation of newer agents into induction chemotherapy protocols for the HPV negative patients and so HPV detection is important to aid in this selection. HPV tumour status is therefore more important than just providing the prognostic information in these classes of tumours. This article discusses the role and clinical relevance of HPV in HNSCCs.
