Abstract
OBJECTIVE The aim of the present study was to identify the profile of patients diagnosed with oral squamous cell carcinoma (SCC) and factors associated with the clinical stage of the disease. MATERIALS AND METHOD A cross-sectional study was conducted with a sample of 293 medical charts of patients with SCC treated at an oncology reference center in the city of Campina Grande (Brazil) between 2000 and 2006. Descriptive and inferential statistics were performed with robust Poisson regression (α=5%). RESULTS Males (56.6%), non-white individuals (49.0%) and individuals over than 60 years of age (74.1%) were the most affected by SCC. The tongue (35.1%) and palate (21.5%) were the most common sites. A large portion of the patients were smokers (37.6%) and 60.2% were in an advanced stage of the disease. Clinical staging was not associated with sex, age, skin color or drinking and/or smoking habits. CONCLUSION There was a higher incidence of SCC in men, older patients, non-white individuals and smokers. Clinical staging was not associated with the variables analyzed.

Abstract
The aim of this study was to evaluate the demographic and clinical profile of the oral squamous cells carcinoma (OSCC) cases registered in a center of oral diagnosis in southern Brazil. Eight hundred and six individuals with OSCC from 1959 to 2012 were included in this study. The variables recorded were: sex, age, occupation according to workplace, alcohol and tobacco consumption, skin color, tumor location, histological type, clinical appearance, size, evolution time, presence of pain and lymph node metastasis. Descriptive analysis was performed and the associations between variables were assessed using the chi-square and Fisher's exact test, with a confidence level of 5%. OSSC was more common in males (76.6%) aged between 51 to 70 years (53.9%). The most frequent sites were lower lip vermilion (23.3%), tongue (20.2%) and gingiva/alveolar ridge (18.1%). There was a strong association between outdoor occupation and white skin color with lip squamous cell carcinoma (LSCC). OSCC intraoral lesions were commonly more painful, larger than 2 cm and presented lymphatic metastasis. In conclusion, most of the results confirm the data from literature about sex, age, tumor location and occupation. Moreover, the positive correlations between LSCC and occupation, between LSCC and white skin color, and between bigger lesions and presence of pain/cervical metastasis also corroborate the literature data.

Abstract
BACKGROUND Although human papillomavirus (HPV) is considered as a causative factor in oral squamous cell carcinoma (OSCCs), its pathogenetic role is not well established. Moreover, a limited number of studies have compared the techniques of detecting the HPV infection in OSCC. This study aimed at the detection of HPV 16 E6 and E7 DNA in OSCC by quantitative polymerase chain reaction (qPCR) technique. METHODOLOGY This retrospective study included 297 tissue sections obtained from histopathologically confirmed OSCC patients. The classification of tumors as poorly differentiated, moderately differentiated and well differentiated was performed by H&E staining following the WHO criteria for OSCC. The presence of HPV infection was detected by p16INK4A expression, conventional PCR technique, HPV 16 E6, and E7 by qPCR and flow cytometry. All statistical analysis was performed using MedCalc software v.16.4.3. P < 0.05 is considered as statistically significant. RESULTS Of 297 samples, 128 samples were found to be HPV-positive by p16. Of total 128 HPV-positive samples, PCR, E6, and E7 qPCR were positive in 19, 97, and 98 samples, respectively. qPCR techniques were found highly significant in the detection of moderately differentiated (P < 0.0001) and widely differentiated (P < 0.0001) cases. The positivity of E6 qPCR increased as the p16 expression increased. A significant variation in E6 DNA copies was observed in different grades of p16 expression (P < 0.0001). However, overall E7 (5.4 × 105 copies/μL) DNA copies were higher than E6 (7.7 × 103 copies/μL). CONCLUSION qPCR detection of HPV infection is a fast, reliable, and accurate technique gives valuable information about the infection status in terms of viral load.

Abstract
The worldwide annual incidence of oral squamous cell carcinoma (OSCC) is over 300,000 cases with a mortality rate of 48%. This cancer type accounts for 90% of all oral cancers, with the highest incidence in men over 50 years of age. A significantly increased risk of developing OSCC exists among smokers and people who consume alcohol daily. OSCC is an aggressive cancer that metastasizes rapidly. Despite the development of new therapies in the treatment of OSCC, no significant increase in 5-year survival has been recorded in the past decades. The latest research suggests focus should be put on examining tumor stroma activation within OSCC, as the stroma may contain cells that can produce signal molecules and a microenvironment crucial for the development of metastases. The aim of this review is to provide an insight into the factors that activate OSCC stroma and hence faciliate neoplastic progression. It is based on the currently available data on the role and interaction between metalloproteinases, cytokines, growth factors, hypoxia factor and extracellular adhesion proteins in the stroma of OSCC and neoplastic cells. Their interplay is additionally presented using the Systems Biology Graphical Notation in order to sublimate the collected knowledge and enable the more efficient recognition of possible new biomarkers in the diagnostics and follow-up of OSCC or in finding new therapeutic targets.

Abstract
BACKGROUND Only a few studies have evaluated the clinicopathological features of oral squamous cell carcinoma (SCC) in Brazil, and most were conducted in the most industrialized region of the country, i.e. the southeastern region. The aim of this study was to evaluate the clinicopathological features of this malignant neoplasm in northeastern Brazil. DESIGN AND SETTING Retrospective study performed in an oral pathology laboratory in Recife, Brazil. METHODS All cases of oral SCC that occurred between 2000 and 2015 were studied. Clinical data were recorded and histological slides were reviewed. Statistical analysis was performed using the chi-square test (P ≤ 0.05). RESULTS A total of 194 cases were evaluated. The male-to-female ratio was 1.5:1. The mean age was 65.4 years, and only 6.6% of the cases occurred in patients younger than 41 years. Most tumors consisted of well-differentiated SCC (54.6%). CONCLUSIONS The findings of this study highlight the higher prevalence of oral SCC among women and the increasing number of cases among young patients. Thus there is no specific risk group for oral SCC, as in the past. This fact needs to be taken into consideration in clinical routine care, so that apparently innocuous malignant lesions do not go unnoticed in these individuals.

Abstract
BACKGROUND Survivin is an inhibitor protein of apoptosis and plays a role in oral carcinogenesis mechanism. METHODS The aim of this study was to evaluate the effect of smoking in survivin expression of oral mucosa of chronic smokers with and without oral squamous cell carcinoma (OSCC). The study was composed of three groups: Group 1-26 patients smoking more than 20 cigarettes/day/10 years without either history of oral malignant neoplasia or visible clinical signs in the examined site; Group 2-26 patients with OSCC; Group 3-22 patients surgically treated for OSCC for at least 1 month. The immunohistochemistry was performed with 1 smear for each group and analyzed by microscopy regarding extension, intensity of positive cells for survivin, and intracellular location. RESULTS The survivin expression was observed in 100% of the cases in Group 1, 88.5% in Group 2, and 100% in Group 3. Concerning to Groups 1 and 3, the survivin expression with cytoplasmic location occurred in 100%, while in Group 2 occurred in 87.5%. The cytoplasmic and nuclear expression was observed only in Group 2, with 7.69%. The results were correlated with clinical-pathological data by Fischer's exact test with significant relation between smoking cessation and intensity (P = .015) for Group 2. CONCLUSIONS The extension and intensity of survivin expression in the cytological smears were related to the smoking cessation in the group with OSCC. However, the smoking history (packs/years) did not influence the survivin expression.

Abstract
BACKGROUND Incidence rates for oral tongue squamous cell carcinoma (SCC) are steadily rising worldwide. METHODS All patients diagnosed with primary oral tongue SCC at the 5 university hospitals in Finland from 2005 to 2009 were studied. The mean follow-up time was 43 months (median, 54 months; range, 0-111 months). RESULTS Three hundred sixty patients with primary oral tongue SCC were identified. Treatment with curative intent was provided for 328 patients (91%). The 5-year disease-specific survival (DSS) rates were as follows: stage I 87%; stage II 73%; stage III 69%; and stage IV 51%. The 5-year recurrence-free survival in general has improved from 47% in our previous published series (1995-1999) to 65% in the current series (p < .001). CONCLUSION The outcome of oral tongue SCC has significantly improved in Finland. However, the relatively high number of disease recurrences in patients with stage I and II disease, when compared with patients with stage III and IV disease, calls for an investigation of new treatment approaches. © 2017 Wiley Periodicals, Inc.

Abstract
Chordomas are rare bone tumors that arise from notochord remnants. They most commonly occur in the sacrum, but they also can be seen in the skull base, cervical spine, and thoracolumbar vertebrae. Chordomas account for 1 to 4% of all primary skeletal tumors. They are usually indolent, locally growing tumors. Distant metastasis has been reported in 3 to 48% of cases. When metastasis occurs, it is usually observed in the lung, bone, and liver. To the best of our knowledge, no case of a chordoma metastasis to the tongue has been previously reported in the literature. We report such a case in a 61-year-old man.

Abstract
BACKGROUND/AIM This study aimed to examine the demographics and histopathological features of oral cavity cancers (OCCs) managed in our clinic. MATERIALS AND METHODS Patients who were diagnosed with OCCs in the Gazi University Otorhinolaryngology Department between the years 1993 and 2013 were retrospectively enrolled in the study. Surgical archive charts and pathology records were reviewed in detail regarding the anatomical and histopathological profiles of the tumors, as well as the demographic data of the patients. RESULTS Out of 230 patients with OCCs, the most common anatomic location and histopathological diagnosis were found to be the oral tongue (41.4%) and squamous cell carcinoma (SCC) (84.3%), respectively. A marked predominance of SCC was observed in all subsites of the oral cavity except the hard palate location. The mean age at presentation was 55.5 ± 13.4 years (±SD). The male:female ratio was found to be 2.2:1. A male predominance was also present in all subsites except the retromolar trigon. CONCLUSION OCCs particularly concern the elderly population with a male predominance. The most common location and histopathological type are the oral tongue and SCC, respectively.

Abstract
INTRODUCTION The most common etiology for Oral Squamous Cell Carcinoma (OSCC) is tobacco and tobacco related products which cause nuclear damage to the keratinocytes. The chemical carcinogens not only affect the lining of oral epithelium but also affect the lining epithelium of the excretory ducts of the salivary glands. Thus, there is a possibility of epithelial dysplasia of the salivary duct epithelium which may lead to potential malignant transformation. AIM The study was performed to see the changes in the minor salivary glands and excretory ducts in cases of oral epithelial dysplasia and OSCC. MATERIALS AND METHODS A total of 278 archival cases of mild, moderate and severe epithelial dysplasia, carcinoma in situ, OSCC including verrucous carcinoma were histopathologically evaluated to observe changes in the excretory ducts and the minor salivary glands. RESULTS In the study there were 56.5% males and 43.5% females. The age group that was most commonly affected in both the sexes was 50-60 yr old. Buccal mucosa was the most common site of involvement. Ductal changes observed in the excretory duct include simple hyperplasia, metaplastic changes such as mucous, oncocytic & squamous, and infiltration of inflammatory cells and malignant cells. Acinar changes observed were degeneration, squamous metaplasia, myoepithelial cell proliferation and inflammatory cell infiltration. Both the excretory ducts and ducts within the gland showed dysplasia. CONCLUSION According to observations in our study it is suggested that histopathological interpretation for oral mucosal lesions especially oral epithelial dysplasias and OSCC should also include changes related to salivary gland tissue to provide a better treatment plan and prevent recurrence of the malignant tumours.

Abstract
Background Oral squamous cell carcinoma (OSCC) is the most common form of oral cancer, in this study, the association between OSCC and oral yeast carriage was investigated. Findings 20 patients having OSCC as well as 40 healthy controls were tested for the presence of yeasts in the oral cavity. Fungal burdens were examined by colony forming unit determinations, while the different yeast genera in patient samples were identified by matrix-associated laser desorption/ionization-time of flight-mass spectrometry. We found that the level of oral yeast carriage was significantly higher in patients with OSCC that was accompanied by a higher diversity of yeasts in the oral cavity of these patients. We also examined the extracellular enzyme production of isolated Candida spp.; however, we found that there was no association between the lipase/protease producing capacity of Candida strains and the higher colonisation rate of neoplastic epithelium. Conclusions In conclusion, our results corroborate the findings of previous studies regarding the association between oral yeast carriage and epithelial carcinoma.

Abstract
OBJECTIVE To investigate disease recurrence among patients with oral squamous cell carcinoma (OSCC) and positive lymph node lesions receiving different therapy for different stages of the disease. STUDY DESIGN One hundred sixty-one patients with biopsy-proven pN1 and pN2+ carcinomas were reviewed retrospectively. We investigated postoperative disease recurrence when using surgery alone (SA), adjuvant radiotherapy (RT), or adjuvant radiochemotherapy (RCT) and compared our results with the 2012 German guidelines. RESULTS Among the study population, 60 (37%) experienced postoperative disease recurrence, 38% with SA, 42% with adjuvant RT, and 39% with adjuvant RCT (P = .420). In the case of pN1, the recurrence rate was 14% with SA, 32% with RT, and 33% with RCT (P = .156); and in pN2+, 60%, 49%, and 29%, respectively (P = .012). CONCLUSIONS Surgery plus adjuvant therapy has benefits with respect to postoperative disease recurrence in pN2+ OSCC. In pN1, surgery alone might be as effective as adjuvant RT or RCT.

Abstract
Background Matrix metalloproteinases (MMPs) are endopeptidases that can degrade extracellular matrix components and affect invasiveness and aggressiveness of oral squamous cell carcinoma (OSCC). The aim of this study was to examine the immunohistochemical expression of MMP-2 and MMP-8 in OSCCs in patients presenting at the Tertiary Health facility in Nigeria. Material and Methods Formalin-fixed, paraffin-embedded (FFPE) OSCC samples diagnosed between the years 2010 and 2012 were used for his study. The FFPE were processed for MMP-2 and MMP-8 using the specifications of the manufacturer. Two investigators reviewed the slides scoring the pattern and intensity of staining as negative (0), weakly positive (+1), moderately positive (+2) and strongly positive (+3). The data were analysed using version 20 of the SPSS. The level of significance was set at P < 0.05. Results Twenty-five OSCC consisting of 14 (56%) males and 11 females (44%) were used. The mean age was 54.6 ± 17.9 years. A higher proportion (100%) of poorly differentiated OSCC strongly expressed MMP-2 compared with the well differentiated and moderately differentiated OSSC. There was no significant difference in the expression of MMP-2 amongst the three grades of OSCC (X2 = 2.87; p= 0.17). Only 5 (20%) OSCC cases positively expressed MMP-8. Moderate expression of MMP-8 was only seen in well-differentiated OSCCs. Conclusions This study showed that a higher proportion of poorly differentiated OSSC strongly expressed MMP-2. Eighty percent of cases that express MMP-8 were females and moderate expression of MMP-8 was seen only in well differentiated OSCC. Key words:Oral squamous cell carcinoma, MMP-2, MMP-8, immunohistochemistry.

Abstract
ABSTRACT
Background
To describe oral lesions diagnosed during oral cancer prevention campaign performed in Fernandópolis, Brazil, in 2015.
Materials and methods
Patients who attended for the Basic Health Units of the city of Fernandópolis on the day of the campaign were examined by dental surgeons who searched for oral lesions clinically suggestive for oral squamous cell carcinoma (SCC) or potentially malignant lesions. Final diagnosis was obtained by a re-evaluation of patients with suspicious lesions performed by an expert in oral diseases.
Results
Seven hundred and sixty-two patients were examined during the campaign; although 96 (12.59%) presented with oral suspicious lesions and forwarded for re-evaluation, only 72 (9.44%) attended for re-evaluation and got the final diagnosis. Among re-evaluated patients, only 1 (1.38%) was diagnosed with oral SCC, whereas 56 (77.77%) were diagnosed with oral benign lesions, and 19 (26.38%) were diagnosed with oral normality variations.
Conclusion
Oral cancer low diagnosis rate detected during this campaign might be attributed to lacks on oral cancer prevention campaign methodologies, which clearly needs to be improved aiming to reach patients in real risk for oral cancer development. Furthermore, oral benign lesions diagnosis among patients forwarded with suspicious lesions rates suggests a lack on dental surgeons’ knowledge regarding oral cancer.
