Abstract
BACKGROUND AND OBJECTIVES Oral squamous cell carcinoma (OSCC) is one of the most common malignancies in the head and neck region. Particularly, high incidence rates are observed in South and Southeast Asia, attributed to the widespread use of the carcinogenic areca nut. This study aimed to investigate the clinical, epidemiological, and histopathological features of OSCC, identify prognostic factors impacting disease-free survival, and determine a post-diagnosis disease-free survival time of OSCC patients. METHODOLOGY Employing a descriptive cross-sectional design, the study conducted a thorough examination of the clinical, epidemiological, and histopathological aspects of OSCC among patients seeking care at a tertiary healthcare facility. Participants were personally interviewed if available, while information for unreachable or deceased individuals was extracted from archival patient records in the Oral and Maxillofacial Surgery Department, Bakhtawar Amin Medical and Dental College, Multan, Pakistan. Data analysis was performed with a significance level set at p ≤ 0.05. RESULTS The mean age of the patients was 54.16 ± 11.1, with a notable concentration in the 41 years and above age group, indicating a significant prevalence of OSCC in this population. The data revealed a gender bias toward males, and a substantial proportion of patients, particularly those aged 41 years and above, had unfortunately passed away. Statistical analysis using the Fisher exact test showed a significant association between age groups and patients' current living status (p-value < 0.05). CONCLUSION Histopathologically, moderately differentiated OSCC was the most frequently encountered grade, and surgery emerged as the predominant treatment modality. The majority of patients studied had a survival period of three years or less, emphasizing the need for further exploration of factors influencing prognosis and treatment outcomes in OSCC.

Head Neck Pathol 2023; 17:697-707. [PMID: 37486536 PMCID: PMC10514008 DOI: 10.1007/s12105-023-01576-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/17/2023] [Accepted: 07/11/2023] [Indexed: 07/25/2023]
Abstract
BACKGROUND Survival rates of head and neck squamous cell carcinoma (HNSCC) have only marginally improved in the last decades. Hence there is a need for predictive biomarkers for long-time survival that can help to guide treatment decisions and might lead to the development of new therapies. The phosphatidylinositol 3-kinase (PI3K)/AKT/mTOR signaling pathway is the most frequently altered pathway in HNSCC, genes are often mutated, amplificated and overexpressed causing aberrant signaling affecting cell growth and differentiation. Numerous genetic alterations of upstream and downstream factors have currently been clarified. However, their predictive value has yet to be established. Therefore we assess the predictive value of p-mTOR, p-ERK and PTEN expression. METHODS Tissue microarrays (TMA's) of HPV-negative patients with oropharyngeal (n = 48), hypopharyngeal (n = 16) or laryngeal (n = 13) SCC, treated with primary chemoradiation (cisplatin/carboplatin/cetuximab and radiotherapy), were histologically stained for p-mTOR, PTEN and p-ERK. Expression was correlated to overall survival (OS), disease free survival (DFS) and locoregional control (LRC). Also p-mTOR was histologically stained in a separate cohort of HNSCC organoids (n = 8) and correlated to mTOR-inhibitor everolimus response. RESULTS High p-mTOR expression correlated significantly with worse OS in multivariate analysis in the whole patient cohort [Hazar Ratio (HR) 1.06, 95%CI 1.01-1.11, p = 0.03] and in the cisplatin/carboplatin group with both worse OS (HR 1.09, 95%CI 1.02-1.16, p = 0.02) and DFS (HR 1.06, 95%CI 1.00-1.12, p = 0,04). p-ERK expression correlated significantly with DFS in univariate analysis in the whole patient cohort (HR 1.03, 95%CI 1.00-1.05, p = 0.04) and cisplatin/carboplatin group (HR 1.03, 95%CI 1.00-1.07, p = 0.04). PTEN-expression did not correlate with OS/DFS/LRC. Better organoid response to everolimus correlated significantly to higher p-mTOR expression (Rs = - 0.731, p = 0.04). CONCLUSIONS High p-mTOR expression predicts and high p-ERK expression tends to predict worse treatment outcome in HPV negative HNSCC patients treated with chemoradiation, providing additional evidence that these markers are candidate prognostic biomarkers for survival in this patient population. Also this study shows that the use of HNSCC organoids for biomarker research has potential. The role of PTEN expression as prognostic biomarker remains unclear, as consistent evidence on its prognostic and predictive value is lacking.

Abstract
Upper aerodigestive tract (UADT) malignancies account for significant proportion of all malignancies. The aim of the study is to know the demography and patterns of tobacco consumption and the proportion of non-tobacco consumers in patients with UADT carcinoma. Patient diagnosed with primary UADT carcinoma visiting outpatient department in a tertiary centre from February 2009 to May 2011 were included in the study. 150 patients were documented with UADT carcinoma and analysed. Among these 133 were males and 17 were female. 40% of them had smoking, 25% had smokeless tobacco, 13% had both smoking and smokeless tobacco and 22% hadn't had any form of tobacco. Carcinoma larynx is the most common site and glottis is the commonest subsite. Most individuals who developed UADT carcinoma have used tobacco in some form. The high proportion of UADT carcinoma in non-tobacco consumer is alarming.

Abstract
This study aimed to explore the clinical and prognostic characteristics of primary salivary gland-type carcinoma (SGC). The entire cohort from the Surveillance, Epidemiology, and End Results database was used to calculate the SGC proportion. In total, 253,096 eligible patients, including 165,715 adenocarcinomas (ADCs), 87,062 squamous cell carcinomas (SCCs), and 319 SGCs, were selected to perform survival analyses. The data of 42 SGC patients from our hospital showed postoperative survival. Overall survival (OS) curves for different histological and surgical types were presented. The proportion of primary SGCs was 0.8 per 1000 patients. Patients with age ≤ 64 years old had a much higher proportion of SGC than those patients with age >64 years old. After adjusting for other confounders, among ADCs, SCCs, and SGC, SGCs had the best prognosis (HR 0.361, p < 0.001). Moreover, the 5-year OS rates of SGC patients were 55% and 7% in the group with surgery or without surgery, respectively (p < 0.001). The data of 42 patients from our hospital also showed a good survival of SGCs. Lobectomy improved the survival of SGCs significantly (adjusted HR 0.439, p = 0.016). In conclusion, pulmonary SGCs had the best prognosis among ADCs, SCCs, and SGCs. In addition, lobectomy could further improve the prognostic outcomes of SGCs.

A Prospective Comparative Analysis Regarding the Assessment of Oral Mucosal Disease Using a Validated Questionnaire to Improve the Teaching of Dental Students. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:9663. [PMID: 35955017 PMCID: PMC9368512 DOI: 10.3390/ijerph19159663] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Revised: 08/02/2022] [Accepted: 08/03/2022] [Indexed: 06/15/2023]
Abstract
Structured examination and treatment are essential in medicine. For dental students, a structured approach to the assessment of oral mucosal lesions is missing thus far. To validate an approach, a structured questionnaire was compared with the habitually used free description of oral lesions (white lesions, ulcers, hyperplasia). Thirty-three dental students were divided into two groups (Group 1 (n = 17) used the free description; Group 2 (n = 16) used a guided questionnaire) to characterize mucosal lesions in patients and make a tentative diagnosis. Although no difference was found between the groups regarding the suspected diagnosis or the histopathological findings, there was a significant advantage of the structured questionnaire in all aspects of the description compared to the free description (p = 0.000018). Thus, a structured description is an important aspect in the evaluation of oral mucosal changes, and a guided questionnaire should be implemented in the study of dentistry.

Abstract
Objective. The diagnostic value of optical enhanced endoscopy in early cancer of upper digestive tract was studied by comparing the disease accuracy, tumor type, invasion, and various surgical indicators between the two groups. Methods. 188 patients with early upper gastrointestinal cancer treated in our hospital from January 2020 to February 2021 were selected as the research objects. The patients were randomly divided into the observation group and control group with 94 cases in each group. Results. The accuracy of early detection of early carcinoma of upper digestive tract in the observation group was 94.68% and that in the control group was 76.60%. The accuracy of the observation group was significantly higher than that in the control group, with statistical significance (
). In the observation group, 36 cases of early gastric cancer, 28 cases of early esophageal cancer, and 30 cases of early colorectal cancer were detected; 25 cases of early gastric cancer, 19 cases of early esophageal cancer, and 28 cases of early colorectal cancer were detected; 26 cases of early carcinoma of upper digestive tract infiltration were detected; and 68 cases were not detected, and the detection rate was 27.66%, which was higher than 9.57% in the control group, and the difference was statistically significant (
). After different methods of treatment, no death occurred in all patients. Except for the operation time, the surgical indexes of the observation group were better than the control group, the difference was statistically significant (
). Conclusion. Optical enhanced endoscopic technique had obvious effect in the diagnosis of patients with early cancer of upper digestive tract, it was helpful to improve the clinical detection rate of early carcinoma of upper digestive tract and had certain diagnostic ability for the invasion depth of early cancer of high upper gastrointestinal tract, which was conducive to the detection of clinical invasion lesions and had high clinical promotion and application value.

Abstract
Objectives The Gram‐negative anaerobic rod Porphyromonas gingivalis (P. gingivalis) is regarded as a keystone pathogen in periodontitis and expresses a multitude of virulence factors iincluding fimbriae that are enabling adherence to and invasion in cells and tissues. The progression of periodontitis is a consequence of the interaction between the host immune response and periodontal pathogens. The aim of this study was to investigate the genome‐wide impact of recombinant fimbrial protein FimA from P. gingivalis W83 on the gene expression of oral squamous carcinoma cells by transcriptome analysis. Materials and Methods Human squamous cell carcinoma cells (SCC‐25) were stimulated for 4 and 24 h with recombinant FimA. RNA sequencing was performed and differential gene expression and enrichment were analyzed using gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and REACTOME. The results of transcriptome analysis were validated using quantitative real‐time polymerase chain reaction (PCR) with selected genes. Results Differential gene expression after 4 and 24 h revealed upregulation of 464 (4 h) and 179 genes (24 h) and downregulation of 69 (4 h) and 312 (24 h) genes. GO, KEGG, and REACTONE enrichment analysis identified a strong immunologic transcriptomic response signature after 4 h. After 24 h, mainly those genes were regulated, which belonged to cell metabolic pathways and replication. Real‐time PCR of selected genes belonging to immune response and signaling demonstrated strong upregulation of CCL20, TNFAIP6, CXCL8, TNFAIP3, and NFkBIA after both stimulation times. Conclusions These data shed light on the RNA transcriptome of human oral squamous carcinoma epithelial cells following stimulation with P. gingivalis FimA and identify a strong immunological gene expression response to this virulence factor. The data provide a base for future studies of molecular and cellular interactions between P. gingivalis and oral epithelium to elucidate basic mechanisms that may provide new prospects for periodontitis therapy and give new insights into the development and possible treatments of cancer.

Abstract
Overexpression of histone deacetylase 6 (HDAC6) and bromodomain-containing protein 4 (BRD4) is related to aggressiveness of head and neck squamous carcinoma (HNSCC). Based on studies that HDAC6 and BRD4 are potential therapeutic targets of HNSCC, we hypothesized that the combination treatment of BET inhibitor JQ1 and HDAC6-selective inhibitor ACY-241 could exhibit synergistic anticancer effects in human papillomavirus (HPV)-positive and HPV-negative HNSCC cells. In this study, HNSCC cell growth and viability were measured by CCK-8 assay, apoptosis was analyzed by flow cytometry, and metastasis was studied by wound healing and transwell assays. Furthermore, immunoblotting is conducted to investigate proteins that modulate apoptosis or metastasis. Here, we report that the combination of ACY-241 and JQ1 shows synergistic cell growth inhibition, viability reduction, and apoptosis induction in HNSCC cells through inactivation of AKT and NF-κB signaling. Importantly, we demonstrate that combined treatment of ACY-241 and JQ1 synergistically suppresses TNF-α-induced migration and invasion via dysregulating matrix metalloproteinase (MMP)-2, MMP-9, and MT1-MMP. Overall, the combination of ACY-241 and JQ1 significantly suppresses proliferation and metastasis in HPV-positive and HPV-negative HNSCC. Collectively, these findings suggest that the co-inhibition of BET and HDAC6 can be a new therapeutic strategy in HNSCC.

Abstract
Objectives: To evaluate changes in incidence and survival of patients diagnosed with hypopharyngeal cancer (HPC) in Denmark in the period 1980-2014.Methods: All patients registered with HPC in the Danish Cancer Registry (DCR) in the period 1980-2014 were included. Age-adjusted incidence rates (AAIRs), average annual percentage change in incidence, and overall survival were calculated.Results: Two thousand and nine patients were included (79.7% men). The overall AAIR increased significantly from 0.3 per 100,000 to 1.1 per 100,000 during the study period, corresponding to an increase of 4.1% per year. The most frequent histology was squamous cell carcinoma (SCC) comprising 90.3%. The overall five-year survival increased with 13.5 percentage points from 13.4% in the period 1980-1985 to 26.9% in the period 2010-2014. Women demonstrated better survival compared to men with a hazard ratio of 0.83, and patients with SCC had better survival compared to the remaining histology groups.Conclusions: This nation-wide study, covering nearly four decades, showed a significant increase in incidence and survival of HPC in Denmark.

Abstract
Cadmium (Cd) is a heavy metal that is extremely toxic to many organisms; however, microbes are highly adaptable to extreme conditions, including heavy metal contamination. Bacteria can evolve in the natural environment, generating resistant strains that can be studied to understand heavy-metal resistance mechanisms, but obtaining such adaptive strains usually takes a long time. In this study, the genome replication engineering assisted continuous evolution (GREACE) method was used to accelerate the evolutionary rate of the Escherichia coli genome to screen for E. coli mutants with high resistance to cadmium. As a result, a mutant (8mM-CRAA) with a minimum inhibitory concentration (MIC) of 8 mM cadmium was generated; this MIC value was approximately eightfold higher than that of the E. coli BL21(DE3) wild-type strain. Sequencing revealed 329 single nucleotide polymorphisms (SNPs) in the genome of the E. coli mutant 8mM-CRAA. These SNPs as well as RNA-Seq data on gene expression induced by cadmium were used to analyze the genes related to cadmium resistance. Overexpression, knockout and mutation of the htpX (which encodes an integral membrane heat shock protein) and gor (which encodes glutathione reductase) genes revealed that these two genes contribute positively to cadmium resistance in E. coli. Therefore, in addition to the previously identified cadmium resistance genes zntA and capB, many other genes are also involved in bacterial cadmium resistance. This study assists us in understanding the mechanism of microbial cadmium resistance and facilitating the application of heavy-metal remediation.

Sumi S, Umemura N, Adachi M, Ohta T, Naganawa K, Kawaki H, Takayama E, Kondoh N, Sumitomo S. The luminance ratio of autofluorescence in a xenograft mouse model is stable through tumor growth stages. Clin Exp Dent Res 2018; 4:174-181. [PMID: 30386639 PMCID: PMC6203828 DOI: 10.1002/cre2.126] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2018] [Revised: 07/11/2018] [Accepted: 07/13/2018] [Indexed: 12/25/2022] Open
Abstract
The aim of this research was to investigate the value of autofluorescence imaging of oral cancer across different stages of tumor growth, to assist in detecting tumors. A xenograft mouse model was created with human oral squamous cell carcinoma cell line HSC-3 being subcutaneously inoculated into nude mice. Tumor imaging was performed with an autofluorescence imaging method (Illumiscan®) using the luminance ratio, which was defined as the luminance of the tumor site over the luminance of normal skin tissue normalized to a value of 1.0. This luminance ratio was continuously observed postinoculation. Tumor and normal skin tissues were harvested, and differences in the concentrations of flavin adenine dinucleotide and nicotinamide adenine dinucleotide were examined. The luminance ratio of the tumor sites was 0.85 ± 0.05, and there was no significant change in the ratio over time, even if the tumor proliferated and expanded. Furthermore, flavin adenine dinucleotide and nicotinamide adenine dinucleotide were significantly lower in tumor tissue than in normal skin tissue. A luminance ratio under 0.90 indicates a high possibility of tumor, irrespective of the tumor growth stage. However, this cutoff value was determined using a xenograft mouse model and therefore requires further validation before being used in clinical diagnosis.

Abstract
PURPOSE The aim of this systematic review and meta-analysis was to investigate the relationship between the Red Cell Distribution Width (RDW) and prognosis in upper aerodigestive tract (UADT) cancer. METHODS PubMed (via the web), Embase, Scopus, and the Cochrane Library were searched. A systematic review and meta-analysis was done to generate the pooled hazard ratios (HR) for overall survival (OS), disease specific survival (DSS), and recurrence free survival (RFS). RESULTS Our analysis included the results of 4200 patients in 8 cohorts. The pooled data demonstrated that an elevated RDW was associated with significantly poorer OS (HR: 1.44, 95% CI: 1.13-1.83), RFS (HR: 1.43, 95%CI: 1.13-1.82). The DSS result had high heterogeneity and 95% CI was not pooled. CONCLUSIONS An elevated RDW may be an indicator of poor prognosis in UADT cancers in certain populations. Further research is needed to confirm this effect.

Abstract
Head and neck squamous cell carcinoma (HNSCC) is a global disease and mortality burden, necessitating the elucidation of its molecular progression for effective disease management. The study aims to understand the molecular profile of three candidate cell cycle regulatory genes, RBSP3, LIMD1 and CDC25A in the basal/ parabasal versus spinous layer of normal oral epithelium and during head and neck tumorigenesis. Immunohistochemical expression and promoter methylation was used to determine the molecular signature in normal oral epithelium. The mechanism of alteration transmission of this profile during tumorigenesis was then explored through additional deletion and mutation in HPV/ tobacco etiological groups, followed byclinico-pathological correlation. In basal/parabasal layer, the molecular signature of the genes was low protein expression/ high promoter methylation of RBSP3, high expression/ low methylation of LIMD1 and high expression of CDC25A. Dysplastic epithelium maintained the signature of RBSP3 through high methylation/ additional deletion with loss of the signatures of LIMD1 and CDC25A via deletion/ additional methylation. Similarly, maintenance and / or loss of signature in invasive tumors was by recurrent deletion/ methylation. Thus, differential patterns of alteration of the genes might be pre-requisite for the development of dysplastic and invasive lesions. Etiological factors played a key role in promoting genetic alterations and determining prognosis. Tobacco negative HNSCC patients had significantly lower alterations of LIMD1 and CDC25A, along with better survival among tobacco negative/ HPV positive patients. Our data suggests the necessity for perturbation of normal molecular profile of RBSP3, LIMD1 and CDC25A in conjunction with etiological factors for head and neck tumorigenesis, implying their diagnostic and prognostic significance.

Abstract
This article illustrates and discusses the applications and value of magnetic resonance imaging (MRI) in the evaluation of sinonasal disease. There are several clinical scenarios where MRI can add value over conventional computed tomography (CT) evaluation of the sinonasal spaces. Specifically, MRI can provide insight through better depiction of the anatomy of certain sinonasal sub-sites including the olfactory structures. It can aid in evaluating anosmia, sinusitis (fungal sinusitis and complications), benign and malignant lesions, CSF leaks and pathology extending into sinonasal spaces.

Abstract
Objectives To determine the levels of carbohydrate antigen 125 (CA125) and tissue polypeptide-specific antigen (TPS) in saliva of patients with oral squamous cell carcinoma (OSCC) and patients with nonneoplastic disease of the oral cavity, and to investigate their diagnostic value and their relationship with pathological grade and clinical stage. Methods A total of 97 hospitalized patients with OSCC, 36 patients with nonneoplastic disease of the oral cavity and 50 healthy individuals were included in this investigation. Mixed saliva was collected from these patients and the healthy controls before treatment. Saliva samples were analyzed by enzyme-linked immunosorbent assay (ELISA). Results The saliva CA125 and TPS concentrations were significantly higher in patients with OSCC than in patients with nonneoplastic disease and healthy controls, but not significantly different between patients with nonneoplastic disease and controls. Neither the saliva CA125 nor the TPS level was correlated with pathological grade and clinical stage. The sensitivity, specificity and accuracy of saliva CA125 and TPS for the diagnosis of OSCC were 80.0%, 66.0%, 75.7%, and 82.1%, 74.0%, 79.3%, respectively. When CA125 and TPS were analyzed independently, there was no significant difference in sensitivity, specificity and accuracy between the two markers. When CA125 and TPS were analyzed in combination, there was no significant difference in sensitivity, specificity and accuracy between independent detection and combined detection. Conclusions The saliva CA125 and TPS concentrations were elevated in patients with OSCC. CA125 and TPS may prove to be useful tumor markers in OSCC.

Abstract
ASC (Apoptosis-associated Speck-like protein containing a CARD) acts as a platform protein in the inflammasome cascade of some cancer types. However, its potential involvement in OSCC (oral cavity squamous cell carcinoma) has not yet been determined. Here, we investigated the potential role of ASC in OSCC. RT-qPCR analysis of 20 paired tumor and adjacent normal tissue samples revealed that the mRNA levels of ASC, along with IL-1β, CASP1, and NLRP3 in ASC-associated NLRP3 inflammasome were significantly elevated in OSCC tissues. Immunohistochemical staining of these four proteins in 111 clinical specimens revealed that high-level expression of ASC was significantly associated with tumor stage, node stage (p=0.001), overall stage (p<0.001), extracapsular spread (p<0.001), perineural invasion (p=0.004) and tumor depth (p<0.001). Kaplan-Meier survival analysis further revealed that high-level ASC expression was correlated with poorer overall survival (p=0.001), disease-specific survival (p<0.001) and disease-free survival (p<0.001). Studies using OSCC cell lines indicated that high-level ASC expression enhanced cell migration and invasion, and experiments using an orthotropic nude mouse model confirmed that ASC overexpression induced metastasis of OSCC cells. This is the first report to show that ASC contributes to OSCC metastasis, and that high-level ASC expression is a marker for poor prognosis in OSCC patients.

Abstract
Background The purpose of this study was to determine prognostic factors influencing outcomes of surgical treatment in patients with T4a hypopharyngeal cancer. Methods The present study enrolled 93 patients diagnosed with T4a hypopharyngeal cancer who underwent primary surgery between January 2005 and December 2015 at six medical centers in Korea. Primary tumor sites included pyriform sinus in 71 patients, posterior pharyngeal wall in 14 patients, and postcricoid region in 8 patients. Seventy-two patients received postoperative radio(chemo)therapy. Results Five-year disease-free survival (DFS) and disease-specific survival (DSS) rates were 38% and 45%, respectively. In univariate analysis, 5-year DFS was found to have significant and positive correlations with margin involvement (p < 0.001) and extracapsular spread (p = 0.025). Multivariate analysis confirmed that margin involvement (hazard ratio (HR): 2.81; 95% confidence interval (CI): 1.49-5.30; p = 0.001) and extracapsular spread (HR: 2.08; 95% CI: 1.08-3.99; p = 0.028) were significant factors associated with 5-year DFS. In univariate analysis, cervical lymph node metastasis (p = 0.048), lymphovascular invasion (p = 0.041), extracapsular spread (p = 0.015), and esophageal invasion (p = 0.033) were significant factors associated with 5-year DSS. In multivariate analysis, extracapsular spread (HR: 2.98; 95% CI: 1.39-6.42; p = 0.005) and esophageal invasion (HR: 2.87; 95% CI: 1.38-5.98; p = 0.005) remained significant factors associated with 5-year DSS. Conclusion Margin involvement and extracapsular spread are factors influencing recurrence while extracapsular spread and esophageal invasion are factors affecting survival in patients with T4a hypopharyngeal cancer treated by primary surgery.

Abstract
Hypopharyngeal cysts are very uncommon pathology. They are presented in adult people over 60 years. Although oncocytic cysts are benign tumors, an incomplete resection causes recurrence. The symptoms are not specific, but the more frequent are dyspnea and foreign body sensation upon swallowing. Diagnosis usually is under general anesthesia during intubation. A flexible fiberoptic laryngoscopy could be insufficient; the trumpet maneuver during this examination can reveled occult cysts. To perform a total resection, the surgeon must have a complete exposition of the operative field. We present a new case of a patient with a symptomatic hypopharyngeal cyst successfully treated with transoral robotic extirpation; our view was tridimensional magnified and the robotic instruments provided great range of movement that permitted complete and safe removal hypopharyngeal lesion.

Abstract
Head and neck cancers from a diverse group of neoplasms, the occurrence of which can be attributed to habitual tobacco use, race, alcohol consumption, ultraviolet (UV) exposure, occupational exposure, viruses, and diet. The surging incidence rates reflect the prevalence of risk factors such as tobacco use (smoked and smokeless), betel nut chewing, urbanization and issues relating to urban air quality. Urbanization and development have catalyzed a multifold rise in levels of pollution in metropolitan cities. Ever-increasing consumption of fuels to meet demands of the growing population coupled with industrial activity has adversely affected the air quality, especially in developing countries. The cause most neglected in risk assessment of aerodigestive tract cancer research is that from petroleum exposure. The global issue of petroleum carcinogenicity has assumed high proportions. Polycyclic aromatic hydrocarbons and heavy metals are essential constituents of total petroleum hydrocarbons which infiltrate into the environment and are recognized worldwide as priority pollutants because of their toxicity and carcinogenicity. High levels of sulfur dioxide, nitrogen dioxide, ozone, carbon monoxide, ammonia and particulate matter PM10 has skyrocketed aerodigestive tract diseases especially carcinomas. The identification of specific biomarkers and role of metal ions in aerodigestive tract cancers will indicate the molecular basis of disease to provide quality care for patients confronting new threats from climate-sensitive pathologies. There is an urgent need to evaluate existing public health infrastructure so as to take ameliorative and adaptive measures.

Abstract
Background We identified rs17071138 T/C, rs3744941 C/T, and rs8089104 T/C gene polymorphisms of SERPINB5 (mammary serine protease inhibitor) that are specific to patients with oral cancer susceptibility and their clinicopathological status. Methodology/Principal findings In total, 1342 participants, including 601 healthy controls and 741 patients with oral cancer, were recruited for this study. Allelic discrimination of rs17071138 T/C, rs3744941 C/T, and rs8089104 T/C of the SERPINB5 gene was assessed by a real-time PCR with a TaqMan assay. We found that individuals carrying the polymorphic rs17071138 and rs8089104 are more susceptible to oral cancer (OR, 1.57; 95% CI, 1.07~2.31 and OR, 1.58; 95% CI, 1.04~2.39, respectively). Among oral cancer-related risk factor exposures, the individuals carrying the polymorphic rs17071138 had 4.26- (95% CI: 1.65~11.01; p = 0.002), 2.34- (95% CI: 1.19~4.61; p = 0.01), and 2.34-fold (95% CI: 1.38~3.96; p = 0.001) higher risks of developing oral cancer. Conclusions Heterozygous TC of the SERPINB5 rs17071138 polymorphism may be a factor that increases susceptibility to oral cancer. Interactions of gene-to-gene and gene-to-oral cancer-related environmental risk factors have a synergetic effect that can further enhance oral cancer development.

Abstract
INTRODUCTION Upper aero-digestive tract cancer is a multidimensional problem, international trends showing complex rises and falls in incidence and mortality across the globe, with variation across different cultural and socio-economic groups. This paper seeks some explanations and identifies some research and policy needs. METHODOLOGICAL APPROACH The literature illustrates the multifactorial nature of carcinogenesis. At the cellular level, it is viewed as a multistep process involving multiple mutations and selection for cells with progressively increasing capacity for proliferation, survival, invasion, and metastasis. Established and emerging risk factors, in addition to changes in incidence and prevalence of cancers of the upper aero-digestive tract, were identified. RISK FACTORS Exposure to tobacco and alcohol, as well as diets inadequate in fresh fruits and vegetables, remain the major risk factors, with persistent infection by particular so-called "high risk" genotypes of human papillomavirus increasingly recognised as also playing an important role in a subset of cases, particularly for the oropharynx. Chronic trauma to oral mucosa from poor restorations and prostheses, in addition to poor oral hygiene with a consequent heavy microbial load in the mouth, are also emerging as significant risk factors. CONCLUSIONS Understanding and quantifying the impact of individual risk factors for these cancers is vital for health decision-making, planning and prevention. National policies and programmes should be designed and implemented to control exposure to environmental risks, by legislation if necessary, and to raise awareness so that people are provided with the information and support they need to adopt healthy lifestyles.

Impact of Maspin Polymorphism rs2289520 G/C and Its Interaction with Gene to Gene, Alcohol Consumption Increase Susceptibility to Oral Cancer Occurrence. PLoS One 2016; 11:e0160841. [PMID: 27525723 PMCID: PMC4985127 DOI: 10.1371/journal.pone.0160841] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2016] [Accepted: 07/26/2016] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND The purpose of this study was to identify gene polymorphisms of mammary serine protease inhibitor (Maspin) specific to patients with oral cancer susceptibility and clinicopathological status. METHODOLOGY/PRINCIPAL FINDINGS Three single-nucleotide polymorphisms (SNPs) of the Maspin gene from 741 patients with oral cancer and 601 non-cancer controls were analyzed by real-time PCR. The participants with G/G homozygotes or with G/C heterozygotes of Maspin rs2289520 polymorphism had a 2.07-fold (p = 0.01) and a 2.01-fold (p = 0.02) risk of developing oral cancer compared to those with C/C homozygotes. Moreover, gene-gene interaction increased the risk of oral cancer susceptibility among subjects expose to oral cancer related risk factors, including areca, alcohol, and tobacco consumption. CONCLUSION G allele of Maspin rs2289520 polymorphism may be a factor that increases the susceptibility to oral cancer. The interactions of gene to oral cancer-related environmental risk factors have a synergetic effect that can further enhance oral cancer development.

Abstract
Objectives: We performed a prospective study to determine the cutoff value and the prognostic value of Cyfra 21–1, a serum tumor marker, in head and neck squamous cell carcinoma (HNSCC). Methods: The serum concentration of Cyfra 21–1 was measured in a group of 300 patients (group 1) with HNSCC, in a control group of 71 healthy subjects (group 2), and in a group of 73 patients with a nonmalignant tumor or inflammatory disease (group 3). The concentrations were compared between the various groups and subgroups; the cutoff value was calculated with a receiver operating characteristic curve. Furthermore, the serum concentrations of Cyfra 21–1 before treatment in the group of 300 patients were compared with the stage of the disease and with the evolution of the overall survival rate and the disease-free survival rate. Finally, to determine whether Cyfra 21–1 is an independent prognostic factor, we compared the concentrations, by a Cox model, with the classic prognostic factors of HNSCC. Results: At the cutoff value of 1 ng/mL, the specificity was 94% and the sensitivity was 72%. The serum concentrations of Cyfra 21–1 were statistically correlated with the stage of the disease. The overall survival rate and the disease-free survival rate were lower in patients with high serum concentrations, and these differences were statistically significant (p <.001). The Cox model allows us to conclude that Cyfra 21–1 is a prognostic marker that is independent of other classic prognostic factors. Conclusions: Cyfra 21–1 is an interesting tumor marker that could be proposed for the early detection of HNSCC with a cutoff value of 1 ng/mL. Furthermore, Cyfra 21–1 can be considered an independent prognostic marker.

Abstract
BACKGROUND The world wide pattern of oral and maxillofacial surgical conditions has rarely been reported despite its significance in ensuring quality of care. A large number of patients are managed surgically in Oral and Maxillofacial Surgery department of Dhaka Dental College Hospital but there has been no surgical audit to identify the potential problems in patient care. OBJECTIVES The aim of this study was to identify the pattern of oral and maxillofacial conditions in patients of maxillofacial surgery of Dhaka Dental College Hospital, which would provide valuable information to build up the focus of attention, to develop a future strategy plan, to improve its clinical care and extend the academic and research field. PATIENTS AND METHODS A retrospective survey of oral and maxillofacial surgical cases managed at the inpatient Department of Oral and Maxillofacial Surgery, Dhaka Dental College Hospital. All admitted patients from 1st January, 2012 to 31st December, 2012 were included in this study. The patients' data were retrieved from the wards registers and patient records. The data were recorded as age, sex, occupation, geographic distribution, diagnosis, treatment done and operation name. These were studied to assess the prevalence of age, sex, diseases and the name of the treatment offered. Analysis of major groups of diagnosis on the basis of age and sex was also studied. Mortality was also recorded. RESULTS Between 1st January, 2012 and 31st December, 2012 a total of 768 patients were treated. Among them 494 patients were male while 274 were female, male female ratio was 1.80:1. The majority of the patients were from Dhaka division. The mean age of the patients was 33.20 years; peak age group was 15-30 years. The most common diagnosis was maxillofacial injuries (35 %), followed by oral squamous cell carcinoma (22 %) and odontogenic tumours and hamartomas (11 %). Maxillo-mandibular fixation or wiring was the main modality of treatment. The mortality rate was 0.26 % of total patients. CONCLUSIONS The department of Oral and Maxillofacial Surgery, Dhaka Dental College Hospital is a busy centre for specialized maxillofacial services in Bangladesh. A good number of patients with a wide range of oral and maxillofacial surgical conditions are managed here. Maxillofacial injury and oral cancer are the two most common conditions encountered here.

Abstract
Imaging evaluation of sinonasal tumors is most often conducted with computed tomography, which excels at identifying the effects of these masses on adjacent osseous structures, and magnetic resonance imaging that is ideal for distinguishing pathologic masses from mucosal thickening and fluid that are common in the sinonasal spaces and depicting extension into the surrounding soft tissues, orbits, and intracranial compartment. Accordingly, the two studies are complementary exams and both are commonly utilized in the assessment of these masses. Less commonly, positron emission tomography can provide additional metabolic evaluation of potential metastatic disease in patients with malignant disease. While these imaging modalities are excellent for the portrayal of an abnormality, there is considerable overlap in the imaging appearance of these tumors and specific imaging manifestations linked to a particular tumor are frequently lacking. Therefore, while the mass may be readily identified, narrowing the differential diagnosis to a single specific entity is rare. Nevertheless, cross-sectional imaging plays an essential role in patient management and valuable guidance for successful biopsy or surgical resection in virtually all cases. This review emphasizes essential imaging manifestations that correlate with sinonasal tumors in general and highlight certain features that may implicate a specific disease process.

Abstract
Aerodigestive cancers are on an increasing level in both occurrence and mortality. A major cause in many of these cancers is disruption of the inflammatory pathway, leading to increased cell proliferation, and epigenetic silencing of normal regulatory genes. Here we review the research on several natural products: silibinin, silymarin, quercetin, neem & nimbolide, gingerol, epigallatecatechin-3- gallate, curcumin, genistein and resveratrol conducted on aerodigestive cancers. These types of cancers are primarily those from oral cavity, esophagus/windpipe, stomach, small and large intestine, colon/rectum and bile/pancreas tissues. We report on the utilization in vivo and in vitro systems to research these dose effects on the inflammatory and epigenetic pathway components within the aerodigestive cancer. To follow up on the basic research we will discuss remaining research questions and future directions involving these natural products as putative stand alone or in combination with clinical agents.

Abstract
BACKGROUND It is sometimes stated anecdotally that patients with head and neck cancer have poor oral health at the time of oncology diagnosis; however, there is little data in the literature to confirm or refute this claim. AIM To assess, in the first UK study of its type, the oral health status of 100 patients attending for a dental assessment at a single centre before head and neck cancer treatment was commenced. SUBJECTS Sixty-six male patients and 34 female patients were included. RESULTS Of all 100 patients, 2% (2/100) were edentulous. Of the dentate patients, 71% (70/98) were clinically diagnosed with periodontal disease. Fifty-one percent (50/98) had a maximum probing pocket depth in excess of 6 mm. The mean number of carious teeth per dentate subject was 2.4 (95% C.I. 1.6-3.1). Sixty-one percent (60/98) of dentate patients presented with one or more carious teeth. CONCLUSIONS Within this cohort, head and neck cancer patients had poor oral health at the time of oncology diagnosis, with caries and periodontal disease being important clinical issues. The implications for the dental management of these patients are discussed.

Low-molecular-mass secretome profiling identifies HMGA2 and MIF as prognostic biomarkers for oral cavity squamous cell carcinoma. Sci Rep 2015; 5:11689.

Abstract
The profiling of cancer cell secretomes is considered to be a good strategy for identifying cancer-related biomarkers, but few studies have focused on identifying low-molecular-mass (LMr) proteins (<15 kDa) in cancer cell secretomes. Here, we used tricine-SDS-gel-assisted fractionation and LC-MS/MS to systemically identify LMr proteins in the secretomes of five oral cavity squamous cell carcinoma (OSCC) cell lines. Cross-matching of these results with nine OSCC tissue transcriptome datasets allowed us to identify 33 LMr genes/proteins that were highly upregulated in OSCC tissues and secreted/released from OSCC cells. Immunohistochemistry and quantitative real-time PCR were used to verify the overexpression of two candidates, HMGA2 and MIF, in OSCC tissues. The overexpressions of both proteins were associated with cervical metastasis, perineural invasion, deeper tumor invasion, higher overall stage, and a poorer prognosis for post-treatment survival. Functional assays further revealed that both proteins promoted the migration and invasion of OSCC cell lines in vitro. Collectively, our data indicate that the tricine-SDS-gel/LC-MS/MS approach can be used to efficiently identify LMr proteins from OSCC cell secretomes, and suggest that HMGA2 and MIF could be potential tissue biomarkers for OSCC.

Abstract
Upper aero-digestive tract (UADT) cancers are collectively cancers of various human body sites, such as the oral cavity, pharynx, oesophagus and larynx. Worldwide, they are the fourth most frequent cancer type and the fourth most common cause of mortality from cancer. Many studies have shown that several chronic diseases, such as cancer, which occur more commonly in later adulthood, are influenced by social and psychological circumstances during birth, childhood, adolescence and early adult life. It is suggested that the build up of problematic circumstances throughout life is the cause of disease, rather than circumstances that happen at one point in time. UADT cancer is a chronic disease of complex multifactorial origin and most of the underlying exposures/risks cannot be considered as individual factors or in isolation, as they act at different levels, which differ from time to time. Thus, life-course epidemiology, rather than drawing false dichotomies between different risk factors of the underlying disease, attempts to integrate biological and social risk processes that cause the chronic disease. It studies how socially patterned exposures during all stages of life--childhood, adolescence and early adult--influence disease risk in adulthood and socio-economic position and hence may account for social inequalities in adult health and mortality. Furthermore, varying health effects, according to the timing or duration of exposure to socio-economic circumstances, may indicate important traces to the causes of cancer. In this paper, we have attempted to draw a conceptual framework on the relationships between socio-economic inequalities, oral health risk factors along the life-course of an individual and incidence of UADT cancer.

Abstract
Introduction Cyclin-D1, p53 and EGFR are molecular markers that regulate the cell cycle and play an important role in tumor progression and development. The present study evaluates the prognostic significance of these markers with chemoradiation response in patients of locally advanced oral squamous cell carcinoma (OSCC). Material and method A total of 97 OSCC patients (females = 19 and males = 78), aged 20–67 years and stage III/IV were recruited. Treatment response was assessed according to WHO criteria. Cyclin-D1, p53 and EGFR expressions in tumor tissue was estimated by immunohistochemical (IHC) method and quantified as percentage positive nuclei. Results The positive expression rates of molecular markers were 86.6% for Cyclin-D1, 92.8% for EGFR and 85.6% for p53. The strong positive expressions of both Cyclin-D1 and p53 showed significant association with poor response. The Cox multivariate regression analysis showed coexpressions of Cyclin-D1 and p53 a significant and independent predictor of overall survival (OR = 1.90, 95% CI = 1.45–4.82, p = 0.046) after adjusting the demographic, clinicopathological and radiological response. The strong positive expressions of Cyclin-D1 and p53 and coexpressions of Cyclin-D1, EGFR and p53 showed significant (p < 0.05 or p < 0.01 or p < 0.001) and lower survival as compared to negative or moderate positive expressions and coexpressions, respectively. Conclusion Expressions and coexpressions of Cyclin-D1 and p53 may serve as a prognostic marker in OSCC patients. Cyclin-D1, p53 and EGFR are molecular markers that regulate the cell cycle. Coexpressions of Cyclin-D1, EGFR & p53 serve as prognostic marker in advanced OSCC. p53 alone may serve as prognostic marker in patients of locally advanced OSCC.

Abstract
OBJECTIVE Head and neck squamous cell carcinoma (HNSCC) is a debilitating and deadly disease. We evaluated an easy-to-administer and innovative rinse that assays soluble CD44 and total protein as HNSCC early detection markers. We examined whether the rinse was acceptable and whether the results would promote screening behavior. STUDY DESIGN This is a prospective observational study. METHODS Participants (N = 150) from underserved, low-income Black American backgrounds completed assessments of satisfaction, intention to repeat test, and likely screening behavior after receiving results. Descriptive statistics, t tests, and analysis of variance (ANOVA) were conducted. RESULTS The rinse was highly acceptable to participants and perceived to be acceptable among peers. Participants strongly agreed that they would perform the rinse as prescribed, engage in preventative behaviors if results indicated risk of cancer, and initiate treatment if they had a positive cancer finding. Employed participants slightly disliked the taste of the rinse but were more likely to schedule a follow-up appointment and engage in preventative behaviors based on the results. Those with health-care coverage (including public health insurance) reported that the test was harder to perform than those who were uninsured. CONCLUSION An easy-to-use rinse technique is acceptable and likely to promote screening behavior among Black Americans at risk for HNSCC. Given that many cancer screening modalities are considered unpleasant to undergo, this rinse holds promise for promoting screening behaviors and, thereby, may result in early detection of this potentially fatal disease.

Abstract
Objective This study aimed to investigate the impact of demographic and socioeconomic factors on survival in patients with major salivary gland malignancies. Study Design Population-based study using the Surveillance, Epidemiology, and End Results (SEER) cancer database. Subject and Methods The study cohort consisted of 10,735 men and women ages 20 and older who were diagnosed with major salivary gland carcinoma from 1973 to 2009. Results Kaplan–Meier analysis revealed that the overall and disease-specific survival was higher for women than for men ( P < .001). Overall and disease-specific survival decreased with increasing age ( P < .001) and differed by race ( P < .001) and marital status ( P < .001). Patients residing in counties with higher rates of high school completion had higher overall and disease-specific survival ( P < .001). Patients residing in counties with higher median household incomes had better overall and disease-specific survival than patients from lower income counties ( P < .001). On multivariable analysis, male sex (hazard ratio [HR] = 1.41; 95% confidence interval [CI], 1.32-1.50), increasing age, and single status (HR = 1.36; 95% CI, 1.27-1.44) had poor prognostic impact on overall survival. Male sex (HR = 1.38; 95% CI, 1.27-1.49), increasing age, and single status (HR = 1.29; 95% CI, 1.19-1.39) had poor prognostic impact on disease-specific survival. Conclusion For patients with salivary gland malignancies, there is a survival benefit for younger patients, female patients, and married patients. This highlights the significance of demographic factors on survival outcomes for patients with salivary gland malignancies and highlights areas for further research on health disparities.

Abstract
While high risk human papillomavirus (HPV) is well established as causative and clinically important for squamous cell carcinoma (SCC) of the oropharynx, its role in non-oropharyngeal head and neck SCC is much less clearly elucidated. In the sinonasal region, in particular, although it is a relatively uncommon site for SCC, as many as 20 % of SCC harbor transcriptionally-active high risk HPV. These tumors almost always have a nonkeratinizing morphology and may have a better prognosis. In addition, specific variants of SCC as well as other rare carcinoma types, when arising in the sinonasal tract, can harbor transcriptionally-active HPV. This article reviews the current literature on HPV in sinonasal carcinomas, attempts to more clearly demonstrate what tumors have it and how this relates to possible precursor lesions like inverted papilloma, and discusses the possible clinical ramifications of the presence of the virus.

Abstract
BACKGROUND The purpose of this study was to identify gene polymorphisms of interleukin-18 (IL-18) -607A/C and -137G/C specific to patients with oral cancer susceptibility and clinicopathological status. METHODOLOGY AND PRINCIPAL FINDINGS A total of 1,126 participants, including 559 healthy people and 567 patients with oral cancer, were recruited for this study. Allelic discrimination of -607A/C (rs1946518) and -137G/C (rs187238) polymorphisms of the IL-18 gene was assessed by a real-time PCR with the TaqMan assay. There was no significant association between IL-18 -607A/C polymorphism and oral cancer risk. However, among alcohol consumers, people with A/A homozygotes of IL-18 -607A/C polymorphism had a 2.38-fold (95% CI=1.17-4.86; p=0.01) increased risk of developing oral cancer compared with those with C/C homozygotes. The participants with G/C heterozygotes of IL-18 -137 polymorphism had a 1.64-fold (95% CI: 1.08-2.48; p=0.02) increased risk of developing oral cancer compared with those with G/G wild type homozygotes. Both sets of statistics were determined after adjusting for confounding factors. Among people who had exposure to oral cancer-related environmental risk factors such as areca, alcohol, and tobacco consumption, the adjusted odd ratios and 95% confidence intervals were increased to a 2.02-fold (95% CI=1.01-4.04; p=0.04), 4.04 (95% CI=1.65-9.87; p=0.002) and a 1.66-fold (95% CI=1.00-2.84; p=0.05) risk of developing oral cancer. However, patients with G/C alleles of IL-18 -137 were correlated with a lower clinical stage (AOR=0.59; 95% CI=0.39-0.89; p=0.01), smaller tumor size (AOR=0.56; 95% CI=0.35-0.87; p=0.01), and non-lymph node metastasis (AOR=0.51; 95% CI=0.32-0.80; p=0.003). CONCLUSION IL-18 -137 G/C gene polymorphism may be a factor that increases the susceptibility to oral cancer, as well as a protective factor for oral cancer progression. The interactions of gene to oral cancer-related environmental risk factors have a synergetic effect that can further enhance oral cancer development.

Abstract
INTRODUCTION: The incidence of oral cancer varies widely in the world, with two thirds of cases diagnosed in developing countries. OBJECTIVE: To investigate the epidemiology of deaths from oral cancer and the spatial distribution in the city of Aracaju in the state of Sergipe between 2000 and 2009. MATERIAL AND METHOD: Data were collected using the Mortality Information System (MIS) of Aracaju/SE at the DATASUS website and were tabulated using the software TABWIN 3.4. The geographic distribution of deaths by neighborhoods of that city was visualized. RESULT: Of the 78 deaths, 61 (78.2%) were male. The mean age was 64.23 years. Individuals of mixed ethnicity had a higher death frequency (34.6%). Regarding education, the majority of death certificates recorded the option ignored, followed by individuals with 1 to 3 years of study. The anatomical sites most affected were unspecified parts of the mouth (43.6%). The spatial distribution analysis indicated that neighborhoods such as Santos Dumont, Luzia, Atalaia, Santa Maria, Cidade Nova and Industrial had the highest death frequencies. CONCLUSION: Males between the fifth and sixth decades of life of mixed ethnicity, low education and in neighborhoods with low and very low standards of living constitute the epidemiological profile for deaths from oral cancer.

An observational study to assess changes in social inequality in smoking-attributable upper aero digestive tract cancer mortality among Canadian males between 1986 and 2001. BMC Public Health 2013; 13:328. [PMID: 23575270 PMCID: PMC3626878 DOI: 10.1186/1471-2458-13-328] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2012] [Accepted: 04/02/2013] [Indexed: 11/16/2022] Open
Abstract
Background Tobacco and low socioeconomic status have been acknowledged as potential risk factors for upper aero-digestive tract (UADT) cancers in North America. In context of reducing adult male smoking prevalence (by over 50%), in the past few decades in Canada, this study tried to document changes in smoking-attributable UADT cancer mortality rates, among Canadian males of different social strata, between 1986 and 2001. Methods The contribution of smoking to UADT cancer mortality was estimated indirectly by using lung cancer mortality as an indicator of the accumulated mortality from smoking in a population. This method was applied to UADT cancer death rates of 35–69 year old socially stratified males. Data, stratified by neighborhood income quintile, could be obtained from Statistics Canada, for four census years, 1986, 1991, 1996, and 2001. Results A total of 2704 male deaths were analyzed. Between 1986 and 2001, UADT cancer deaths reduced by 30% (32 to 22 per 100,000) but the proportion of these deaths attributable to smoking reduced much more, by 41% (22 to 13 per 100,000). In the span of fifteen years, absolute social inequality (measured by rate difference between the highest and the lowest stratum) in smoking-attributable male UADT cancer mortality in Canada reduced by 47% and relative social inequality (measured by rate ratios) reduced by 9%. Conclusion The present analyses reveal that between 1986 and 2001, smoking-attributable UADT cancer mortality rates among adult males (35–69 years) in Canada reduced in all social strata and the social inequalities in these rates have narrowed. Analysis of more current data will be of interest to confirm these trends.

Abstract
BACKGROUND Mucins are high molecular mass glycoproteins whose role in diagnosis, prognosis and therapy is being increasingly recognized owing to their altered expression in a variety of carcinomas. MUC4, a membrane-bound mucin encoded by a gene located on chromosome locus 3q29, is aberrantly expressed in several cancers including those of the bile duct, breast, colon, esophagus, ovary, lung, prostate, stomach and pancreas. OBJECTIVE This review considers the potential use of the MUC4 expression pattern in the diagnosis and prognosis of various cancers. RESULTS/CONCLUSION MUC4 expression is a specific marker of epithelial tumors and its expression correlates positively with the degree of differentiation in several cancers. Importantly, MUC4 has emerged as a specific marker of dysplasia, being expressed in the earliest dysplastic lesions preceding several malignancies, including lethal pancreatic cancer. The presence of MUC4-specific antibodies in the serum and of the transcript in peripheral blood mononuclear cells of cancer patients raises the possibility of it emerging as a new diagnostic biomarker for bedside application in high-risk individuals and those with established cancer.

Abstract
PURPOSE Despite continuous improvement of treatment regimes, the mortality rates for non-small cell lung cancer (NSCLC) and head and neck squamous cell carcinoma (HNSCC) remain disappointingly high and novel anticancer agents are urgently awaited. EXPERIMENTAL DESIGN We combined the data from genome-wide siRNA screens on tumor cell lethality in a lung and a head and neck cancer cell line. RESULTS We identified 71 target genes that seem essential for the survival of both cancer types. We identified a cluster of 20 genes that play an important role during G2-M phase transition, underlining the importance of this cell-cycle checkpoint for tumor cell survival. Five genes from this cluster (CKAP5, KPNB1, RAN, TPX2, and KIF11) were evaluated in more detail and have been shown to be essential for tumor cell survival in both tumor types, but most particularly in HNSCC. Phenotypes that were observed following siRNA-mediated knockdown of KIF11 (kinesin family member 11) were reproduced by inhibition of KIF11 using the small-molecule inhibitor ispinesib (SB-715992). We showed that ispinesib induces a G2 arrest, causes aberrant chromosome segregation, and induces cell death in HNSCC in vitro, whereas primary keratinocytes are less sensitive. Furthermore, growth of HNSCC cells engrafted in immunodeficient mice was significantly inhibited after ispinesib treatment. CONCLUSION This study identified a wide array of druggable genes for both lung and head and neck cancer. In particular, multiple genes involved in the G2-M checkpoint were shown to be essential for tumor cell survival, indicating their potential as anticancer targets.

Abstract
CONCLUSION Partial laryngopharyngectomy (PLP) provides acceptable oncologic results and laryngeal preservation rate in selected patients with squamous cell carcinoma of the hypopharynx. Even when local recurrence develops, the chance of successful salvage is still high. OBJECTIVES To evaluate the oncologic results and laryngeal preservation rate in patients with squamous cell carcinoma of the hypopharynx who underwent PLP. METHODS The results of 39 patients who underwent PLP were compared with those of 91 patients who underwent total laryngectomy (TL). RESULTS The distribution of the primary T stages were 23 (59%) pT2, 9 (23%) pT3, and 7 (18%) pT4; the pathologic stages were 8 patients (21%) stage II, 9 (23%) stage III, and 22 (56%) stage IV. All of the patients also had ipsilateral or bilateral neck dissections. Eighteen patients (46%) received postoperative adjuvant therapy. After a median follow-up of 39 months, 17 patients (44%) had recurrence, including 12 local, 2 regional, and 3 distant lesions. The 5-year overall and disease-specific survival were 44% and 56%, respectively; functional preservation was 62%. The recurrence rate was similar in patients treated with PLP and TL (44% vs 36%, p = 0.431); the local recurrence rate was higher after PLP than after TL (31% vs 8%, p = 0.001). The salvage surgery was successful in four of the six patients (67%). After salvage treatment, the 5-year overall survival (44% vs 47%) and disease-specific survival (56% vs 62%) were similar in the two groups.

Abstract
Primary adenocarcinoma of the oropharynx most often arises from the minor salivary glands, and primary squamous cell carcinoma is more commonly seen arising from the tongue. Few cases of adenocarcinoma not otherwise specified of the tongue have been reported in the literature, and none found on the dorsum of the tongue. Successful treatment strategies have therefore not been defined.We report a case of adenocarcinoma located on the dorsum of the posterior one third of the tongue adjacent to the circumvallate papillae in a woman presenting with globus sensation and mild dysphagia. Treatment consisted of transoral laser excision and postoperative external-beam radiotherapy, resulting in disease-free survival at her 5-year follow-up. The goals of this report are to present a case of adenocarcinoma arising from the minor salivary gland located on the dorsum of the tongue, to discuss previous reports of similar cases, and to suggest that surgery with or without radiotherapy be used as the mainstay of treatment.
