Abstract
Introduction: Oral squamous cell carcinoma (OSCC) is the most common malignant tumor occurring in the oral cavity. Aim: The present study was conducted to evaluate the biomarkers such as epidermal growth factor receptor (EGFR), human epidermal growth factor receptor 2 (HER2/neu), p53 and Ki67 expression in OSCC cases, and its correlation with other well-established clinicopathological parameters. Materials and Methods: Seventy cases of OSCC cases diagnosed between 2015 and 2019 were included in the study. A technique of manual tissue microarray was employed for the analysis of expression of IHC markers such as EGFR, HER2/neu, p53, and Ki67 in all cases. Results were subjected to the statistical analysis. Results: A statistically significant positive association was noted between EGFR expression and tumor grade, tumor stage, and p53 immunoexpression in OSCC cases. Increased EGFR expression was noted insignificantly in OSCC cases with lymph node (LN) metastasis and Ki67 positive cases. Statistically significant positive association was noted between HER2/neu expression and tumor grade and stage of oral SCC cases. Increased HER2/neu expression was noted insignificantly in OSCC cases with LN metastasis, p53 and Ki67 positive OSCC cases. A statistically significant positive association was noted between percent of tumor cells expressing EGFR, HER2/neu, p53 and Ki67, and grade of OSCC. Conclusion: This study intends to document prognostic utility of EGFR and HER2/neu expression in OSCC cases in the Indian setting and contribute to the data pool which could aid in formulating individual tailored therapy that includes targeted therapy in oral SCC cases.

Abstract
Autophagy is an intracellular degradation mechanism that allows recycling of organelles and macromolecules. Autophagic function increases metabolite availability modulating metabolic pathways, differentiation and cell survival. The oral environment is composed of several structures, including mineralized and soft tissues, which are formed by complex interactions between epithelial and mesenchymal cells. With aging, increased prevalence of oral diseases such as periodontitis, oral cancer and periapical lesions are observed in humans. These aging-related oral diseases are chronic conditions that alter the epithelial-mesenchymal homeostasis, disrupting the oral tissue architecture affecting the quality of life of the patients. Given that autophagy levels are reduced with age, the purpose of this review is to discuss the link between autophagy and age-related oral diseases.

Abstract
BACKGROUND: Tongue cancer is one of the most common head and neck cancers in the world. Nowadays, natural compounds are important resources of many anti-cancer drugs. Venom from honey bees possesses potent anti-cancer activities. Cisplatin is a chemotherapeutic drug that has been used for decades to treat cancer cells. Recently, combination therapy has been a popular treatment choice for cancer patients.
AIM: This study was conducted to evaluate the synergistic cytotoxic effect of honey bee venom (BV) and cisplatin on tongue squamous cell carcinoma 25 (SCC-25) cell lines.
METHODS: The cytotoxic effect was determined using methyl thiazol tetrazolium assay, microscopic examination, real-time polymerase chain reaction (RT-PCR), and statistical analysis.
RESULTS: The findings revealed that the cytotoxic potential of the tested drugs on SCC-25 cells was dose-dependent. Microscopic examination showed that BV and cisplatin alone and in combination mainly produced apoptotic cell death. Regarding RT-PCR results, P53 and caspase-3 expression levels were significantly increased in SCC-25-treated cells (p = 0.0001).
CONCLUSION: The combined use of BV and cisplatin induced a marked synergistic cytotoxic effect on SCC-25 cell line.

Abstract
Reinforced extracellular matrix (ECM)-based hydrogels recapitulate several mechanical and biochemical features found in the tumor microenvironment (TME) in vivo. While these gels retain several critical structural and bioactive molecules that promote cell-matrix interactivity, their mechanical properties tend toward the viscous regime limiting their ability to retain ordered structural characteristics when considered as architectured scaffolds. To overcome this limitation characteristic of pure ECM hydrogels, we present a composite material containing alginate, a seaweed-derived polysaccharide, and gelatin, denatured collagen, as rheological modifiers which impart mechanical integrity to the biologically active decellularized ECM (dECM). After an optimization process, the reinforced gel proposed is mechanically stable and bioprintable and has a stiffness within the expected physiological values. Our hydrogel's elastic modulus has no significant difference when compared to tumors induced in preclinical xenograft head and neck squamous cell carcinoma (HNSCC) mouse models. The bioprinted cell-laden model is highly reproducible and allows proliferation and reorganization of HNSCC cells while maintaining cell viability above 90% for periods of nearly 3 weeks. Cells encapsulated in our bioink produce spheroids of at least 3000 μm2 of cross-sectional area by day 15 of culture and are positive for cytokeratin in immunofluorescence quantification, a common marker of HNSCC model validation in 2D and 3D models. We use this in vitro model system to evaluate the standard-of-care small molecule therapeutics used to treat HNSCC clinically and report a 4-fold increase in the IC50 of cisplatin and an 80-fold increase for 5-fluorouracil compared to monolayer cultures. Our work suggests that fabricating in vitro models using reinforced dECM provides a physiologically relevant system to evaluate malignant neoplastic phenomena in vitro due to the physical and biological features replicated from the source tissue microenvironment.

Abstract
OBJECTIVE This review aims to systematically examine the effectiveness of photodynamic therapy for the treatment of patients with recurrent oral squamous cell carcinoma. INTRODUCTION Oral squamous cell carcinoma is a significant public health problem, and is the seventh most common cancer. Its incidence is mainly due to tobacco use, alcohol consumption, and HPV infection. The survival rates are poor due to diagnosis at advanced stages, with high recurrence rates. Although current evidence does not point to photodynamic therapy as a first-line option, this treatment might be suitable for treating recurrent stages of the cancer where conventional treatments were ineffective. Despite the potential of photodynamic therapy, there is a need to verify the scientific evidence to support its indication for the treatment of recurrent oral squamous cell carcinoma. INCLUSION CRITERIA This review will consider studies on any stage of recurrent oral squamous cell carcinoma treated with photodynamic therapy after receiving first-line conventional treatments. Patients of any age, gender, and geographic location will be included. The primary outcomes will be to evaluate response to treatment, focusing on remission, recurrence, change in size of the lesion, alleviation of symptoms, and survival. Secondary outcomes will be postoperative complications, presence of necrosis, patient quality of life after treatment, and patient satisfaction. METHODS Studies will be searched using a combination of index terms and keywords in MEDLINE, Cochrane Central, Web of Science, Embase, and ClinicalTrials.gov. No date limits will be applied. Articles written in English, French, Spanish, or Portuguese will be considered. Findings will be provided as a narrative synthesis, structured around the photodynamic therapy protocol used. A meta-analysis is planned and subgroup analysis will be conducted if possible. The certainty of findings will be assessed. SYSTEMATIC REVIEW REGISTRATION NUMBER PROSPERO CRD42020141075.

Abstract
BACKGROUND AND OBJECTIVES According to the global cancer situation, which is very alarming, with over 10 million new diagnoses and more than 6 million deaths each year globally, cancer is one of the most prominent causes of morbidity and mortality today. One of the cancers is oral cancer. Oral cancer is the irregular development of malignant cells in the oral cavity. The study's objective was to decide the mortality of cross-tabulation among patients treated for oral carcinoma from Hospital Universiti Sains Malaysia (USM), Kelantan, Malaysia. MATERIALS AND METHODS This chapter summarizes the medical history for 7 years from January 2011 to December 2018 of patients who have been treated for oral carcinoma in the Hospital USM, Oral and Maxillofacial Surgery (OMFS) Unit. Each patient's complete medical record was checked, and data gathered were based on age, gender, site lesion, clinical diagnosis, and mortality. Version 26.0 of the SPSS software was used to evaluate the correlation and distribution of patient survival. RESULTS This was a retrospective cross-sectional review of the medical evidence of 117 patients infected for oral carcinoma at OMFS (Hospital USM). Sixty-seven (57.26%) of the patients were male and fifty (42.74%) were female. Patient age ranged from 25 to 93 years. Malay has the highest prevalence (85.5%) in oral carcinoma, followed by a second ethnic group, Chinese (7.7%). The result indicates that the majority of oral carcinoma patients were over 60 years old.Cases of oral squamous cell carcinoma have proved to be the most prevalent malignant tumour in the mouth cavity. The largest number of cases collected is 91% of the data collected. Mucoepidermoid carcinoma (10%) is the second most common small salivary gland tumor. CONCLUSION OSCC is the most prevalent kind of oral cancer. According to the data review, the most popular site for oral cancer is the tongue.

Abstract
Oral squamous cell carcinoma (OSCC) has a high degree of malignancy, which affects the quality of life and prognosis of patients with OSCC. Our study aimed to reveal the function of long non-coding RNA TTN-AS1/microRNA-199a-3p (miR-199a-3p)/runt-related transcription factor 1 (RUNX1) axis in OSCC progression, thereby providing a novel OSCC effective strategy. Real-time quantitative polymerase chain reaction and western blotting were performed to detect the expression of TTN-AS1, miR-199a-3p, and RUNX1 in OSCC. Several cell functional experiments, including Cell Counting Kit-8, flow cytometry, and cell adhesion assays, were used to assess cell proliferation, apoptosis, adhesion, and migration. A luciferase assay was performed to confirm the interaction between TTN-AS1, miR-199a-3p, and RUNX1. Our results revealed that TTN-AS1 and RUNX1 were upregulated in OSCC tissues and cells, whereas miR-199a-3p expression was downregulated. Knockdown of TTN-AS1 or RUNX1 suppressed cell proliferation, adhesion, and migration but induced apoptosis. Additionally, miR-199a-3p inhibitor partly relieved the effects of silencing TTN-AS1 and RUNX1 in OSCC cells due to their targeting relationship. In conclusion, TTN-AS1 and RUNX1 could promote OSCC progression and miR-199a-3p partly relieved the effects of TTN-AS1 and RUNX1.

Abstract
Abstract
Introduction Oral cavity squamous cell carcinomas (OCSCCs) are one of the most common malignancies encountered. They have diverse clinicopathologic profiles. Epidermal growth factor receptor (EGFR) is an important marker of OCSCC for diagnosis, prognosis, and therapy.
Objective The study aimed to evaluate the distribution of clinicopathological parameters in cases of squamous cell carcinoma (SCC) of the oral cavity and adjacent sites and their EGFR expression. An attempt was made to correlate EGFR scores with different parameters.
Materials and Methods An observational retrospective study was undertaken for 1 year. Patients with histologically proven SCC of the oral cavity and adjacent sites were included. Clinicopathologic and immunohistochemical features of each case were analyzed.
Results A total of 59 cases of SCC were included of which 41 (69%) were males. The mean age of the patients was 56.4 ± 10.3 years. The most common location of the tumors was oral cavity (31, 53%) followed by larynx (10, 16%). Most cases were moderately differentiated tumors (31, 53%). Immunohistochemical analysis showed low EGFR score in 7 (11.9%) cases, intermediate in 6 (10.1%), and high in 46 (78%) cases. Association between gender of patients and EGFR score was statistically significant (p = 0.000159). Most lesions of the oral cavity (31 cases, 53%) had a high EGFR score (23 cases, 74.2%). A statistically significant correlation was found between tumor grade and EGFR score (p = 0.03338).
Conclusion This study from eastern region of India reveals unique characteristics of EGFR expression in SCC of the oral cavity and adjacent sites.

Abstract
In this study, a novel, low-cost, and flexible paper-based electrochemical immunosensor was developed for the bioanalysis of Cyfra 21.1 biomarker in human saliva samples by using stabilization of synthesis Ag nano-ink on the surface of paper using pen-on-paper technology. The employed electrochemical techniques for the evaluation of immunoplatform performance were differential pulse voltammetry and chronoamperometry. Also, the prepared immunosensor showed great ability in the determination of Cyfra21.1 in human saliva specimens. Under the optimized conditions, the obtained linear range was from 0.0025 to 10 ng/mL, and the obtained LLOQ was 0.0025 ng/mL. The developed immunosensor is easy to prepare, sensitive, cost-effective, portable, and simple. So proposed immunoplatform can be an accomplished biodevice in clinical laboratories. The proposed paper-based immunosensor could be a hopefully new and cheap tool for the diagnosis of other biomarkers. Also, the prepared immunosensor showed great ability in the determination of Cyfra21.1 biomarker in human saliva specimens.

Abstract
Oral squamous cell carcinoma (OSCC) remains one of the most challenging clinical problems in the field due to its high rate of locoregional and distant metastases. However, studies that assess the association between aspirin use and survival in patients with OSCC are limited. Moreover, patients that recruited from those studies might have tumors that arose from different anatomic regions of the head and neck, including the oral cavity, oropharynx, etc. Since tumors within these distinct anatomic regions are unique in the context of epidemiology and tumor progression, we sought to evaluate the association of aspirin use with squamous cell carcinomas located within the oral cavity only. In this 10-year cohort study, we evaluated aspirin use and survival rates in relation to clinical characteristics as well as duration of aspirin use in patients with OSCC. Our findings suggest that OSCC patients with aspirin use for more than 180 days showed improved overall and disease-specific survival rates. Aspirin also improves survival in patients across various stages of OSCC. Cox regression models indicated that aspirin use was associated with a good prognosis. In conclusion, this evidence indicates that aspirin may be potentially used as an adjuvant therapy for OSCC.

Abstract
Background: Oral cancer is one of the most common type of head and neck cancer, with a 5 year survival rate of < 50%. One of the major problems of oral cancer include the late stage of disease at the time of diagnosis. Mirror image biopsy is a new technique that can be used for detection of early changes in the oral mucosa. Aim of the study: To histologically assess the reflect copy biopsy occupied from clinically usual observing mucosa at consistent contralateral anatomical place to the main lesion in patients identified with tongue squamous cell carcinoma to notice any indication of arena alteration in oral mucosa. Materials and methods: Seven patients diagnosed with squamous cell carcinoma of the tongue underwent reflect copy biopsy from clinically usual observing mucosa at consistent contralateral anatomical place to the main lesion. The reflect copy biopsy example were exposed to histopathological check. Results: of the seven patients included, four were male and three were female, with an age range from 45 years to 64 years (median 54.5 years). One of the biopsies revealed severe dysplasia and six-revealed hyperplasia of the epithelium. Conclusion: Mirror image biopsy is a useful tool to detect the early field changes in oral mucosa in order to prevent further progression to oral cancer.

Differential Angiogenic Potential of 3-Dimension Spheroid of HNSCC Cells in Mouse Xenograft. Int J Mol Sci 2021; 22:ijms22158245.

Abstract
The experimental animal model is still essential in the development of new anticancer drugs. We characterized mouse tumors derived from two-dimensional (2D) monolayer cells or three-dimensional (3D) spheroids to establish an in vivo model with highly standardized conditions. Primary cancer-associated fibroblasts (CAFs) were cultured from head and neck squamous cell carcinoma (HNSCC) tumor tissues and co-injected with monolayer cancer cells or spheroids into the oral mucosa of mice. Mice tumor blood vessels were stained, followed by tissue clearing and 3D Lightsheet fluorescent imaging. We compared the effect of exosomes secreted from 2D or 3D culture conditions on the angiogenesis-related genes in HNSCC cells. Our results showed that both the cells and spheroids co-injected with primary CAFs formed tumors. Interestingly, vasculature was abundantly distributed inside the spheroid-derived but not the monolayer-derived mice tumors. In addition, cisplatin injection more significantly decreased spheroid-derived but not monolayer-derived tumor size in mice. Additionally, exosomes isolated from co-culture media of FaDu spheroid and CAF upregulated angiogenesis-related genes in HNSCC cells as compared to exosomes from FaDu cell and CAF co-culture media under in vitro conditions. The mouse tumor xenograft model derived from 3D spheroids of HNSCC cells with primary CAFs is expected to produce reliable chemotherapy drug screening results given the robust angiogenesis and lack of necrosis inside tumor tissues.

Abstract
BACKGROUND Oral cancer progression is a multi-step process in which adhesion molecules play a pivotal role in the development of recurrent, invasive, and distant metastasis. The aim of this study was to adopt prognostic biomarkers to assess the lymph node metastasis of OSCC that will facilitate in deciding the treatment modality by the surgeons. OBJECTIVES The objectives of the study were to assess the biological behaviour of OSCC by correlating the expression levels of P-Cadherin and WNT5A immunohistochemically. METHODS A total of 60 selected OSCCs cases (lymph node metastasis n = 30, non-metastatic n = 30) and 10 normal healthy controls were quantitatively and qualitatively analysed by immunohistochemistry for P-Cadherin and WNT5A. A survival analysis was also performed. RESULTS The expression levels of P-Cadherin and WNT5A in OSCC groups were statistically significant between metastatic and non-metastatic groups (p < 0.001). P-Cadherin and WNT5A expression in metastatic (lymph node metastasis) and non-metastatic cases showed a significant correlation coefficient of 0.753 at (p < 0.01). The present study also found that the aberrant expression (high) of P-Cadherin was associated with diminished survival of patients with metastatic OSCC. CONCLUSION The present study demonstrated the aberrant expression of P-Cadherin and WNT5A could serve as important prognosticator in OSCC. CLINICAL RELEVANCE P-Cadherin and WNT5A could be used as significant predictors of disease outcome.

Abstract
Metastases derived from primary tumours distant to the oral and maxillofacial region account for only 1% of all malignancies at that location, usually with a poor prognosis. In women, the primary tumours that most frequently metastasise to the oral cavity are breast adenocarcinomas affecting the jawbones and soft tissues (41% and 24%, respectively), followed by adrenal glands and female genital organs to the jawbones (8%), and female genital organs to the soft tissues (15%). Metastatic tumours of the mouth are a challenging diagnosis because of their exceptional occurrence. We report on the case of an 83-year-old woman who consulted for a bleeding ulcerated tumour on the floor of the mouth. A biopsy-confirmed metastasis of an adenocarcinoma of Müllerian origin. The oral lesion was the first sign of undetected cancer. The patient agreed to surgical resection and was further referred to palliative care for her symptoms.

Abstract
Oral squamous cell carcinoma patients are exhausted against the powerful chemotherapies, radiotherapies after the surgery, and their immune system is devastated during the process and antibiotic usage become inescapable. Although prescribing an antibiotic might be fraught for such as drug interaction and undesirable proliferation danger, studies still look for the new ideas such as antibiotic combinations that might be safe to use. The antiproliferative and apoptotic outcomes of levofloxacin with cisplatin combination as well as their single usage were examined with WST-1, Caspase-3/BCA and Annexin V methods on SCC-15 cells and a healthy cell line (MRC-5). 24 h treatment of 50 mM single levofloxacin, 50 mM single cisplatin and 50 mM levofloxacin-cisplatin combination resulted in viability rates of SCC-15 cells as 90%, 67% and 80.8%, respectively. Caspase-3 enzyme activity was enhanced 0.92-fold for single levofloxacin, 13.05-fold for single cisplatin and 9.73-fold for the combination of levofloxacin-cisplatin, the total apoptotic activity of single levofloxacin, single cisplatin and levofloxacin-cisplatin combination were observed as 4.88%, 21.14%, 16.21%, respectively on SCC-15. The apoptotic effect of cisplatin on MRC-5 has been shown to be suppressed when combined with levofloxacin. Considering the cell viability, caspase-3, and apoptotic activity results, it's conclude that the levofloxacin-cisplatin combination was also effective compared to the only cisplatin treatment on OSCC cells. The combination has shown less toxicity for healthy cells than single cisplatin treatment. Therefore, our apoptotic findings suggest that the different dosage combinations are necessary to understand the interaction for the treatment of tongue squamous cell carcinoma.

Abstract
A 74-year-old male with a history of mild cognitive impairment presented to the emergency department with failure to thrive and generalized weakness. He was having difficulty swallowing leading to 30 pounds of unintentional weight loss in the last three months. His social history was significant for 12.5 pack-year smoking and drinking (two to three glasses of wine/day). The oral cavity examination revealed a large (3 × 2 cm2) defect with the erythematous border that encompassed the mid-palatal structures and emanated from the hard palate into his nasal cavity. Auto-immune work-up was negative. Palatal biopsy showed squamous cell carcinoma (SCC; well-differentiated). A diagnosis of locally advanced (stage IVa) oral cavity squamous cell carcinoma (OSCC) was made based on PET scan findings. A palatal obturator (prosthesis) was placed to improve his eating, prevent regurgitation. The patient opted for palliative care and did not want to pursue further treatment. He was discharged home with a regular follow-up visit.

Abstract
Background Oral squamous cell carcinoma (OSCC) has increased in incidence from 1990 to 2017, especially in South and Southeast Asia. It is often diagnosed at an advanced stage with a poor prognosis. Therefore, early detection of OSCC is essential to improve the prognosis of OSCC. This study aims to identify the differentially expressed serum proteins as potential biomarkers for oral squamous cell carcinoma (OSCC). Methods Comparative proteomics profiling of serum samples from OSCC patients, oral potentially malignant disorder (OPMD) patients, and healthy individuals were performed using two-dimensional gel electrophoresis (2-DE) coupled with mass spectrometry (MS) (n = 60) and bioinformatics analysis. The enzyme-linked immunosorbent assay (ELISA) (n = 120) and immunohistochemistry (IHC) (n = 70) were used to confirm our findings. Results The 2-DE analysis revealed that 20 differentially expressed proteins were detected in OPMD and OSCC (p < 0.05). Bioinformatics analysis indicated that the activation of classical complement, liver X receptor/retinoid X receptor (LXR/RXR) activation, and acute phase response signaling pathway are associated with the development and progression of OSCC. Most of the detected proteins are acute-phase proteins and were related to inflammation and immune responses, including apolipoprotein A-I (APOA1), complement C3 (C3), clusterin (CLU), and haptoglobin (HP). The expression levels of CLU and HP in ELISA are consistent with the findings from the 2-DE analysis, except for the mean serum level of HP in OPMD, whereby it was slightly higher than that in control. IHC results demonstrated that CLU and HP are significantly decreased in OSCC tissues. Conclusion Decreased expression of CLU and HP could serve as complementary biomarkers of OSCC. These proteins may assist in predicting the outcomes of OSCC patients. However, a larger cohort is needed for further investigation.

Abstract
The promise of speech disorders as biomarkers in clinical examination has been identified in a broad spectrum of neurodegenerative diseases. However, to the best of our knowledge, a validated acoustic marker with established discriminative and evaluative properties has not yet been developed for oral tongue cancers. Here we cross-sectionally collected a screening dataset that included acoustic parameters extracted from 3 sustained vowels /ɑ/, /i/, /u/ and binary perceptual outcomes from 12 consonant-vowel syllables. We used a support vector machine with linear kernel function within this dataset to identify the formant centralization ratio (FCR) as a dominant predictor of different perceptual outcomes across gender and syllable. The Acoustic analysis, Perceptual evaluation and Quality of Life assessment (APeQoL) was used to validate the FCR in 33 patients with primary resectable oral tongue cancers. Measurements were taken before (pre-op) and four to six weeks after (post-op) surgery. The speech handicap index (SHI), a speech-specific questionnaire, was also administrated at these time points. Pre-op correlation analysis within the APeQoL revealed overall consistency and a strong correlation between FCR and SHI scores. FCRs also increased significantly with increasing T classification pre-operatively, especially for women. Longitudinally, the main effects of T classification, the extent of resection, and their interaction effects with time (pre-op vs. post-op) on FCRs were all significant. For pre-operative FCR, after merging the two datasets, a cut-off value of 0.970 produced an AUC of 0.861 (95% confidence interval: 0.785-0.938) for T3-4 patients. In sum, this study determined that FCR is an acoustic marker with the potential to detect disease and related speech function in oral tongue cancers. These are preliminary findings that need to be replicated in longitudinal studies and/or larger cohorts.

Abstract
Oral tongue squamous cell carcinomas (OTSCCs) have an increasing incidence in young patients, and many have an aggressive course of disease. The objective of this study was to identify candidate prognostic protein markers associated with early-onset OTSCC. We performed an exploratory screening for differential protein expression in younger (≤45 years) versus older (>45 years) OTSCC patients in The Cancer Genome Atlas (TCGA) cohort (n = 97). Expression of candidate markers was then validated in an independent Austrian OTSCC patient group (n = 34) by immunohistochemistry. Kaplan-Meier survival estimates were computed, and genomic and mRNA enrichment in silico analyses were performed. Overexpression of protein kinase C alpha (PRKCA) was significantly more frequent among young patients of both the TCGA (p = 0.0001) and the Austrian cohort (p = 0.02), associated with a negative anamnesis for alcohol consumption (p = 0.009) and tobacco smoking (p = 0.02) and poorer overall survival (univariate p = 0.02, multivariate p< 0.01). Within the young subgroup, both overall and disease-free survival were significantly decreased in patients with PRKCA overexpression (both p < 0.001). TCGA mRNA enrichment analysis revealed 332 mRNAs with significant differential expression in PRKCA-upregulated versus PRKCA-downregulated OTSCC (all FDR ≤ 0.01). Our findings suggest that PRKCA overexpression may be a hallmark of a novel molecular subtype of early-onset alcohol- and tobacco-negative high-risk OTSCC. Further analysis of the molecular PRKCA interactome may decipher the underlying mechanisms of carcinogenesis and clinicopathological behavior of PRKCA-overexpressing OTSCC.

Abstract
Prodrug-activating suicide gene therapy (PA suicide gene therapy for short) for cancer is to introduce cancer cells with suicide genes. The enzyme encoded by suicide gene is not toxic but is able to kill cancer cells by converting a non-toxic prodrug into a toxic compound. This approach is a promising cancer gene therapy that could reduce non-specific toxicity to normal tissue. However, there is no quantitative method to evaluate efficacy of suicide gene therapy in preclinical study. The aim of this study is to develop a new method to quantitatively evaluate and compare prodrug-activating suicide gene therapies. This study was carried out on an oral squamous cell carcinoma (OSCC) cell line CAL-27. Suicide genes were integrated into ROSA26 locus of CAL-27 by CRISPR-Cas9. CAL-27 cell lines stably expressing herpes simplex virus-thymidine kinase (TK) or yeast cytosine deaminase (CD) were used to evaluate and compare PA suicide gene therapies. The efficacies of PA suicide gene therapies were quantitatively evaluated from three aspects: effective prodrug concentration, prodrug treatment time, and bystander effect. This method also could be used for different types of suicide gene therapies and different types of cancer. When the prodrug concentration, treatment time, and rate of suicide gene-positive cells (related to bystander effect) are fixed, anti-cancer effects could be quantitatively measured. This information is important for suicide gene therapy preclinical development.

Abstract
An oral defect after oncologic resection, especially in the upper jaw, is an extremely complex problem in terms of reconstructive surgery. Herein, we report 2 patients who were diagnosed with oral mucosal squamous cell carcinoma. In one patient, the lesion was present on the right side of the hard palate, invading the maxillary bone. In the other patient, the lesion was present in the left retromolar trigone region. Reconstruction of the postsurgical defects was successfully done using a temporalis muscle flap. Both patients were discharged after ensuring the absence of any postsurgical complications. Furthermore, the postoperative functional and esthetic outcomes were adequate. These case reports highlight the usefulness and reliability of a temporalis muscle flap for the immediate reconstruction of oral and maxillary defects after oncologic resection.

Modulation of the triggered apoptosis by nano emodin transfersome-mediated sonodynamic therapy on head and neck squamous cell carcinoma cell lines. Photodiagnosis Photodyn Ther 2021; 34:102253. [PMID: 33711532 DOI: 10.1016/j.pdpdt.2021.102253] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2020] [Revised: 02/14/2021] [Accepted: 03/05/2021] [Indexed: 12/19/2022]
Abstract
BACKGROUND Non-invasive sonodynamic therapy (SDT) is a new treatment modality that uses low-intensity ultrasound to activate a non-toxic sensitizing chemical agent for cancer therapy in a site-directed manner. This study aimed to investigate the anti-cancer effects of ultrasound combined with nano emodin transfersome (NET) on head and neck squamous cell carcinoma (HNSCC) cell lines. MATERIALS AND METHODS A transfersome form of nano emodin as a novel sono-responsive nanomaterial was synthesized to enhance the accumulation and penetration of nanoparticles. iIn vitro experiments including hemolytic activity, cell proliferation, intracellular reactive oxygen species (ROS) generation, apoptosis induction, DNA fragmentation, and mRNA expressions of caspase 3 and 9 were conducted to explore the anti-cancer effects of NET-SDT on FaDu and CAL-27 cell lines. RESULTS Characterization tests showed the round and uniform morphology of NET with transfersome structure, resulting in a high drug-loading content and encapsulation efficiency. No significant hemolytic activity was observed (P > 0.05). Cytotoxicity gradually increased with increasing concentrations of NET, so that 10 × 10-4 g/L of NET plus 5 min ultrasound irradiation at a frequency of 1 MHz and ultrasonic intensity of 2 W/cm2 effectively killed 98.2 % and 97.3 % of FaDu and CAL-27 cell lines, respectively (P < 0.05). We found that ROS generation in NET-SDT was dose-dependent and the triggered apoptosis and caspase-3/9 gene expression levels were significantly enhanced as the concentration of NET increased (P < 0.05). No significant difference was found in the rate of apoptosis induction and gene expression between two cell lines. CONCLUSIONS Our data demonstrated that SDT with NET as a sonosensitizer can induce apoptosis and significantly decrease cell viability of HNSCC cell lines, which represents the role of NET-SDT as a potent anti-cancer modality.

Abstract
Background Oral and oropharyngeal cancer are significant health problems. They are both life‐threatening conditions usually diagnosed at an advanced stage causing survival rates to decline. Aim To assess and compare practices, knowledge and attitude regarding oral and oropharyngeal cancer between dental and medical practitioners. Methods A cross‐sectional study was conducted to assess knowledge, attitude and practices of oral and oropharyngeal cancer among dental and medical practitioners at King Abdulaziz Medical City, Riyadh, Saudi Arabia. 360 participants were included in the study using a convenient sampling technique. Participants were approached in their clinics and printed self‐administered questionnaire were handed over to them after signing a written consent form. Frequency distribution and Chi‐Square test were used for the statistical analysis and the level of significance was set at P value of .05 or less. Results A total of 174 participants responded. Assessment of oral and oropharyngeal cancer knowledge between dental practitioners and medical practitioners showed comparable results. Regarding practices, a significant difference was seen between medical practitioners and dental practitioners in determining the duration of intra‐oral ulcer to consider urgent referral (P = .006) and in number of referrals made in relation to suspicious oral lesions (P = .002). Moreover, a significant difference (P = .006) was seen between medical practitioners and dental practitioners in determining the duration of intra‐oral ulcer to consider urgent referral. Conclusion Medical and dental practitioners showed areas of differences in practice, attitude and knowledge of oral and oropharyngeal cancer that when addressed would lead to improved survival rates.

Biomedicines 2021; 9:biomedicines9030228.

Abstract
Venous thrombo-embolism (VTE) disease is the second most common cause of mortality in cancer patients, and evaluation and prevention of thrombosis risk is essential. VTE-associated risk varies according to the type of tumor disease. Oral cancer is the most frequent type of head and neck cancer, and it represents approximately 2.1% of all cancers worldwide. Most tumors are squamous cell carcinomas and are mainly due to tobacco and alcohol abuse. VTE risk associated with oral squamous cell carcinoma (OSCC) is low. However, many studies have shown that OSCC has the following biological features of cancers associated with a high thrombosis risk: modified thrombosis and fibrinolysis mechanisms; strong expression of procoagulant proteins; secretion of procoagulant microparticles; and production of procoagulant cytokines. Using an original mouse model of tongue squamous cell carcinoma, our study aimed to clarify this paradoxical situation. First, we showed that OSCC tumors have a pro-aggregatory phenotype and a high local thrombosis risk. Second, we found that tongue tumor mice do not have an elevated systemic thrombosis risk (the risk of an "at distance" thrombosis event such as lower extremity deep venous thrombosis or pulmonary embolism) and even show a reduction in risk. Third, we demonstrated that tongue tumor mice show a reduction in platelet reactivity, which explains the low systemic thrombosis risk. Finally, we found that tongue tumor mice present granule pool deficiency, thereby explaining the reduction in platelet reactivity and systemic thrombosis risk.

Abstract
OBJECTIVE This systematic review aimed to evaluate the epidemiologic profile, screen for possible risk factors, and evaluate the spectrum of clinical characteristics of oral squamous cell carcinoma (OSCC) around dental implants (DIs). METHODS The systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta- Analyses statement. RESULTS Thirty-three articles met the eligibility criteria. In total, the sample consisted of 63 patients, and women comprised the majority (55.5%). The mean age of patients was 66.7 years. Oral potentially malignant disorders were reported in 46% of patients, of which 65.5% occurred in women. The most common lesion found in women was oral lichen planus (52.6%). In 88.8% of patients OSCC around DIs occurred in the mandible, and the most common clinical appearance of the lesions was an exophytic mass (46%). Most of these lesions were initially treated as peri-implantitis. CONCLUSIONS Most patients with OSCC around DIs were women without known risk factors. It is important to emphasize that these lesions may present clinical and radiographic features that could resemble peri-implantitis, which can lead to delay in the diagnosis and subsequent treatment.

MicroRNA-Based Cancer Mortality Risk Scoring System and hTERT Expression in Early-Stage Oral Squamous Cell Carcinoma. JOURNAL OF ONCOLOGY 2021; 2021:8292453.

Abstract
We have previously constructed a novel microRNA (miRNA)-based prognostic model and cancer-specific mortality risk score formula to predict survival outcome in oral squamous cell carcinoma (OSCC) patients who are already categorized into “early-stage” by the TNM staging system. A total of 836 early-stage OSCC patients were assigned the mortality risk scores. We evaluated the efficacy of various treatment regimens in terms of survival benefit compared to surgery only in patients stratified into high (risk score ≥0) versus low (risk score <0) mortality risk categories. For the high-risk group, surgery with neck dissection significantly improved the 5-year survival to 75% from 46% with surgery only (p < 0.001); a Cox proportional hazard model on time-to-death demonstrated a hazard ratio of 0.37 for surgery with neck dissection (95% CI: 0.2–0.6; p=0.0005). For the low-risk group, surgery only was the treatment of choice associated with 5-year survival benefit. Regardless of treatment selected, those with risk score ≥2 may benefit from additional therapy to prevent cancer relapse. We also identified hTERT (human telomerase reverse transcriptase) as a gene target common to the prognostic miRNAs. There was 22-fold increase in the hTERT expression level in patients with risk score ≥2 compared to healthy controls (p < 0.0005). Overexpression of hTERT was also observed in the patient-derived OSCC organoid compared to that of normal organoid. The DNA cancer vaccine that targets hTERT-expressing cells currently undergoing rigorous clinical evaluation for other tumors can be repurposed to prevent cancer recurrence in these high-risk early-stage oral cancer patients.

Abstract
INTRODUCTION The association between uterine cervix and anogenital carcinomas and human papillomavirus, HPV, is well established, however the involvement of this virus in the development of oral squamous cell carcinomas remains controversial. OBJECTIVES To evaluate the relationship between HPV infection and oral squamous cell carcinomas, and to estimate the incidence of this infection in these patients. METHODS Four electronic databases were searched to find studies that met the following inclusion criteria: i) performed in humans; ii) were cohort, case-control or cross-sectional; iii) assessed the HPV oncogenic activity by the E6 and E7 mRNA; iv) included primary oral squamous cell carcinomas which; v) diagnosis had been confirmed by biopsy. Information about the country; study period; sample obtainment; sites of oral squamous cell carcinomas; number, gender and age range of the population; the prevalence of HPV infection and subtypes detected; use of tobacco or alcohol and oral sex practice were extracted. The methodological quality of included articles was assessed using 14 criteria. RESULTS The search strategy retrieved 2129 articles. Assessment of the full text was done for 626 articles, but five were included. The total of participants included was 383, most of them male with mean age between 51.0 and 63.5 years old. Seventeen patients were HPV/mRNA-positive, being the subtypes 16 and 18 detected more frequently. Nine of the HPV/mRNA-positive oral squamous cell carcinomas occurred on the tongue. The quality score average of included articles was five points. CONCLUSIONS Among the 383 oral squamous cell carcinoma patients included, 17 (4.4%) were HPV/mRNA-positive, nevertheless it was not possible to assess if HPV infection was associated with oral squamous cell carcinomas because none of the studies included was longitudinal and cross-sectional investigations do not have control group.

Abstract
BACKGROUND The prediction of overall survival in tongue cancer is important for planning of personalized care and patient counselling. OBJECTIVES This study compares the performance of a nomogram with a machine learning model to predict overall survival in tongue cancer. The nomogram and machine learning model were built using a large data set from the Surveillance, Epidemiology, and End Results (SEER) program database. The comparison is necessary to provide the clinicians with a comprehensive, practical, and most accurate assistive system to predict overall survival of this patient population. METHODS The data set used included the records of 7596 tongue cancer patients. The considered machine learning algorithms were logistic regression, support vector machine, Bayes point machine, boosted decision tree, decision forest, and decision jungle. These algorithms were mainly evaluated in terms of the areas under the receiver-operating characteristic (ROC) curve (AUC) and accuracy values. The performance of the algorithm that produced the best result was compared with a nomogram to predict overall survival in tongue cancer patients. RESULTS The boosted decision-tree algorithm outperformed other algorithms. When compared with a nomogram using external validation data, the boosted decision tree produced an accuracy of 88.7% while the nomogram showed an accuracy of 60.4%. In addition, it was found that age of patient, T stage, radiotherapy, and the surgical resection were the most prominent features with significant influence on the machine learning model's performance to predict overall survival. CONCLUSION The machine learning model provides more personalized and reliable prognostic information of tongue cancer than the nomogram. However, the level of transparency offered by the nomogram in estimating patients' outcomes seems more confident and strengthened the principle of shared decision making between the patient and clinician. Therefore, a combination of a nomogram - machine learning (NomoML) predictive model may help to improve care, provides information to patients, and facilitates the clinicians in making tongue cancer management-related decisions.

Abstract
Background Oral cancer (OC) is a neoplastic process of the oral cavity that has high mortality and significant effects on patients' aesthetics. The majority of OC is oral squamous cell carcinoma (OSCC) and resection remains the most frequent treatment. Recurrence is the main cause of tumor-related mortality. Material and methods A retrospective review of patients' charts at Hamad Medical Corporation examined 154 adults who were diagnosed as OSCC and referred to the national head and neck cancer multi-disciplinary team meetings between 2012 and 2018. The data extracted was demographic, pathologic and clinical. All patients with oral cavity tumors other than squamous cell carcinoma were excluded. Results Males comprised the majority of the sample, mean age was 46.93 years. Tongue was the most common location. The majority of the patients were diagnosed at early stages, and a small subset of patients had histologically-proven local recurrence. Conclusion The young male predominance of OSCC patients in Qatar is unprecedented worldwide. Most patients were non-Qataris, mainly from South Asia. Loss of follow-up was a challenge in assessing the long-term outcomes of OSCC. Our findings suggest the need for a more vigilant surveillance approach to oral lesions particularly in male South-Asian patients, as well as improving the follow-up strategies.

Abstract
Background Nodal metastasis is a critical factor in predicting the prognosis of oral squamous cell carcinoma (OSCC). When patients present with a clinically positive neck, the treatment of choice is radical neck dissection. However, management of a clinically negative neck is still a subject of significant controversy. Aim This study was carried out in order to propose a model to predict regional lymph node metastasis of OSCC using histological parameters such as tumour stage, tumour size, pattern of invasion (POI), differentiation of tumour, and host immune response, together with the expression levels of six biomarkers (periostin, HIF-1α, MMP-9, β-catenin, VEGF-C, and EGFR), and, furthermore, to compare the impact of all these parameters on recurrence and 3 yr and 5 yr survival rates. Materials and Method. Histological materials collected from the archives were used to evaluate histological parameters and immunohistochemical profiles. Standard methods were used for immunohistochemistry and for evaluation of results. Data related to recurrence and survival (3 and 5 years) was also recorded. Clinical data was collected from patients' records. Results Male to female ratio was 3 : 1. The commonest site of OSCC was the buccal mucosa, and majority of them were T3 or T4 tumours presented at stage 4. 62.5% of the tumours were well differentiated. Three-year and 5-year survival rates were significantly associated with lymph node metastasis and recurrence. POI was significantly correlated with tumour size, stage, 3-year survival, EGFR, HIF-1α, periostin, and MMP-9 (p < 0.05). Expression of EGFR showed a direct association with metastasis (p < 0.05). Conclusion POI, level of differentiation, and expression of EGFR are independent prognostic markers for lymph node metastasis. Therefore, these parameters may help in treatment planning of a clinically negative neck.

Abstract
Despite the long-term survival rates of osseointegrated dental implants, several biological complications are known to affect the peri-implant tissues, such as peri-implant mucositis and peri-implantitis. Occasionally, the clinical features of these more common benign lesions, or others nonrelated to implants, might be similar to oral malignancies, leading to misdiagnosis. The objective of this study was to present a case series of oral cancer located adjacent to dental implants, aimed to identify the reasons for initial misinterpretation of diagnosis. Thirteen patients, 10 females and 3 males, aged 59 to 90, were assessed. Among the differential diagnoses established, a malignant or premalignant lesion was not considered in 10 out of the 13 patients. Peri-implantitis was the most common preliminary diagnosis, followed by fungal infection, viral infections, and traumatic ulcers. The meantime for the diagnosis of oral cancer was 21.5 months. The clinical presentation of peri-implant malignancy, such as ulceration, white and red plaques, and exophytic lesions, might mimic benign diseases that are more common in the oral cavity. Suspicious lesions with treatment failure that persist for more than 2 weeks require biopsy and histopathological analysis to establish an early definitive diagnosis to improve the prognosis and quality of life of the patients.

The interplay of the oral microbiome and alcohol consumption in oral squamous cell carcinomas. Oral Oncol 2020; 110:105011. [PMID: 32980528 DOI: 10.1016/j.oraloncology.2020.105011] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2020] [Revised: 08/11/2020] [Accepted: 09/11/2020] [Indexed: 12/24/2022]
Abstract
Oral cancer (OC) is among the top twenty occurring cancers in the world, with a mortality rate of 50%. A shift to a functionally inflammatory or a 'disease state' oral microbiome composition has been observed amongst patients with premalignant disorders and OC, with evidence suggesting alcohol could be exacerbating the inflammatory influence of the oral microorganisms. Alcohol dehydrogenase (ADH, EC 1.1.1.1) converts alcohol into a known carcinogenic metabolite, acetaldehyde and while ADH levels in oral mucosa are low, several oral commensal species possess ADH and could produce genotoxic levels of acetaldehyde. With a direct association between oral microbiome status, alcohol and poor oral health status combining to induce chronic inflammation with increased acetaldehyde levels - this leads to a tumour promoting environment. This new disease state increases the production of reactive oxygen species (ROS), while impairing anti-oxidant systems thus activating the redox signalling required for the promotion and survival of tumours. This review aims to highlight the evidence linking these processes in the progression of oral cancer.

Abstract
The etiological factors of oral cancer are complex including drinking alcohol, smoking tobacco, betel quid chewing, human papillomavirus infection, and nutritional deficiencies. Understanding the molecular mechanism of oral cancer is vital. The traditional treatment for patients with oral squamous cell carcinoma (e.g., surgery, radiotherapy, and chemotherapy) and targeted molecular therapy still have numerous shortcomings. In recent years, the use of phytochemical factors to prevent or treat cancer has received increasing attention. These phytochemicals have little or no toxicity against healthy tissues and are thus ideal chemopreventive agents. However, phytochemicals usually have low water solubility, low bioavailability, and insufficient targeting which limit therapeutic use. Numerous studies have investigated the development of phytochemical delivery systems to address these problems. The present article provides an overview of oral cancer including the etiological factors, diagnosis, and traditional therapy. Furthermore, the classification, dietary sources, anticancer bioactivity, delivery system improvements, and molecular mechanisms against oral cancer of phytochemicals are also discussed in this review.

[PMID: 32488959 PMCID: PMC7301398 DOI: 10.1002/cre2.278] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2019] [Revised: 12/12/2019] [Accepted: 12/13/2019] [Indexed: 01/05/2023] Open
Abstract
OBJECTIVE Reliable data describing the trends and clinicopathological characteristics of oral squamous cell carcinoma (OSCC) in the Nepalese population are very limited. The current study aimed to examine the demographics, trend, and clinicopathological characteristics of OSCC reported to the main referral/tertiary cancer hospital, the B.P. Koirala Memorial Cancer Hospital (BPKMCH) in Nepal for a period of 11 years (1999-2009). MATERIAL AND METHODS This is a cross-sectional study. Data were retrieved retrospectively from hospital register maintained in the Department of Ear, Nose, Throat at BPKMCH, categorized into demographic and clinicopathological variables and SPSS (V25) was used for the analysis. RESULTS In a period of 11 years, 3,452 cases of head and neck cancer were registered at the Department of Ear, Nose, Throat, BPKMCH. Out of 1,111 oral cancer cases, 1,081 (97.3%) were OSCC. A trend for increasing number of OSCCs presenting to BPKMCH was observed during that period. OSCC was found to be more common among males (73.0%), Brahmin/Chhetri ethnic groups (33.0%), in age group of 51-60 years (31.9%), and in Terai region (62.0%). Tongue (42.8%) was the most common site, followed by buccal mucosa (27.2%). Nevertheless, when stratified with respect to the geographical location and ethnicity, buccal mucosa was the most common site for OSCC in Terai region (63.9%, p = .002) and in Madhesi ethnic group (34.2%, p < .001). Majority of OSCC cases were diagnosed at advanced stage (49.7%, Stage IV) and received a combination therapy (42.0%). CONCLUSIONS Hospital-based records can provide valuable information on disease characteristics in countries like Nepal. This study revealed that the clinicopathological characteristics of OSCC in Nepal follow the global trend. Nevertheless, relationship between specific intraoral sites for OSCC with geographic location and ethnic groups is an interesting observation and requires further population-based studies to clarify these findings.

Abstract
Background & Objective: Cell population and turnover are controlled by a balance between cell proliferation and apoptosis. Detection of apoptosis in oral cancer contributes to its better prognosis and improved management. This study aimed to quantify apoptotic cells in leukoplakia and oral squamous cell carcinoma (OSCC) using methyl green-pyronin (MGP) and hematoxylin and eosin (H & E) staining. Methods: The sample included a total of 130 subjects (comprising 108 males and 22 females). Formalin fixed and paraffin embedded tissues were used and categorized into three groups of normal oral mucosa (n=10), leukoplakia with dysplasia (n=60), and OSCC (n=60). The number of apoptotic cells and apoptotic index (AI) were calculated after staining with MGP and routine H & E stained slides. Results: MGP stained the condensed chromatin of apoptotic cells. Statistically significant difference (P≤0.001) was observed among various study groups in terms of numbers of AI and apoptotic cells. Also, AI increased with increasing grades of dysplasia, and it was the highest in well differentiated OSCC. Results were statistically significant in both H & E and MGP stained sections (P≤0.001). A good correlation was found between MGP and H & E staining results. Conclusion: MGP is more specific and can lead to intense staining for chromatin in apoptotic cells. Accordingly, it can provide a good alternative to H&E in identifying apoptotic cells.

Abstract
Abstract
Past decade has seen the advent of several prognosticators for oral squamous cell carcinoma (OSCC). Although TNM staging is still considered as the prognostic gold standard, it is not possible to obtain all the necessary information for a pathological TNM staging until excisional biopsy. Thus, it is necessary to identify features from the initial biopsy, which could aid in early prognostication.
Aim
To compare neutrophil elastase immuno-expression in oral squamous cell carcinoma patients with and without lymph node metastasis.
Materials and Methods
Archival specimens of 50 oral squamous cell carcinoma consisting of 25 cases with and 25 cases without lymph node metastasis were immuno-stained for neutrophil elastase.
Results
Statistically, a significant difference was noted in the neutrophil elastase staining between the 2 groups. 18 of the 25-oral squamous cell carcinoma cases with lymph node metastasis were positive and only 5 of the 25-oral squamous cell carcinoma cases without nodal involvement were positive.
Conclusion
Presence of neutrophil elastase in the lesional tissue is strongly associated with a lymph node involvement, and thus could serve as a prognostic factor for oral squamous cell carcinoma.

Abstract
Objectives Incidence of oral cavity squamous cell carcinomas is rising worldwide, and population characterization is important to follow for future trends. The aim of this retrospective study was to present a large cohort of primary oral cavity squamous cell carcinoma from all four health regions of Norway, with descriptive clinicopathological characteristics and five-year survival outcomes. Materials and methods Patients diagnosed with primary treatment-naïve oral cavity squamous cell carcinomas at all four university hospitals in Norway between 2005–2009 were retrospectively included in this study. Clinicopathological data from the electronic health records were compared to survival data. Results A total of 535 patients with primary treatment-naïve oral cavity squamous cell carcinomas were identified. The median survival follow-up time was 48 months (range 0–125 months) after treatment. The median five-year overall survival was found to be 47%. Median five-year disease-specific survival was 52%, ranging from 80% for stage I to 33% for stage IV patients. For patients given treatment with curative intent, the overall survival was found to be 56% and disease-specific survival 62%. Median age at diagnosis was 67 years (range 24–101 years), 64 years for men and 72 years for women. The male: female ratio was 1.2. No gender difference was found in neither tumor status (p = 0.180) nor node status (p = 0.266), but both factors influenced significantly on survival (p<0.001 for both). Conclusions We present a large cohort of primary treatment-naïve oral cavity squamous cell carcinomas in Norway. Five-year disease-specific survival was 52%, and patients eligible for curative treatment had a five-year disease-specific survival up to 62%.

Abstract
Objective: The aim of current study was to investigate the expression of Cyclin D1 and Ki-67 in primary and metastatic oral squamous cell carcinoma (OSCC) and their different histological grades. Methods: Paraffin embedded 30 oral squamous cell carcinoma (15 each of primary and cervical lymph node metastatic OSCC) were included in the study. Cyclin D1 and Ki 67 expressions were evaluated by immunohistochemistry and compared in primary and lymph node metastasis of OSCC and their histological grades. The data was analyzed using SPSS software. Results: The mean age of patients with primary OSCC was 53.47 ±16.67 years and 61.47 ±11.94 years in patients with metastasis. Males were comparatively affected more than females with tongue as the most common site involved in both primary and metastatic tumours. The mean size of primary and metastatic tumour biopsies were 1.16 mm and 3.93 mm respectively. Comparison of the expression of Cyclin D1 in these primary and metastatic OSCC revealed a statistically significant difference (p = 0.003) whereas it was insignificant for Ki-67 (p = 0.715). Conclusion: Cyclin D1 can be a useful marker in predicting aggressive or metastatic behaviour of OSCC on premier biopsies.

Abstract
BACKGROUND The frequency and distribution of oral potentially malignant disorders (OPMD) may vary among different populations. The aim of the present study was to evaluate the clinical-pathological characteristics of OPMD diagnosed in a Brazilian oral pathology laboratory over a period of 11 years. MATERIAL AND METHODS All cases diagnosed as leukoplakia, speckled leukoplakia, erythroplakia, and actinic cheilitis from 2005 to 2015 were analyzed. Clinical information was obtained from laboratory forms and histological information was obtained from histological slides stained with hematoxylin and eosin. RESULTS the final sample was comprised of 684 cases, of which 292 were males and 392 were females. The mean age was 58 years. The anatomical site most often involved was the lateral border of the tongue (23%), followed by the lower lip (20%), and by the buccal mucosa/vestibule (18%). Leukoplakia accounted for 82% of the sample (564 cases). The mean size of the leukoplakia and speckled leukoplakia lesions was 13 mm (ranging from 1 to 100 mm) and 15 mm (ranging from 5 to 30 mm), respectively (p=0.460). Males reported smoking and drinking alcohol more frequently than females (p=0.001 and p<0.0001, respectively). In half of the cases, dysplasia was not histologically detected, while slight dysplasia was detected in 28% of the cases. The lesions from patients aged from 41 to 80 years presented moderate and severe dysplasia more often than lesions from patients in other age groups. CONCLUSIONS OPMD were more common in females in their sixties. Females were more frequently affected in all anatomical sites, except for the lips. Leukoplakia lesions were the most common OPMD, followed by actinic cheilitis. The lateral border of the tongue was the most affected anatomical site. OPMD located in the floor of the mouth/sublingual mucosa and lesions from older patients presented severe epithelial dysplasia with greater frequency.

Abstract
Around half of all patients with oral squamous cell carcinoma (OSCC) present with lymphatic metastasis, a strong predictor of poor survival. Improving survival rates depends on preventing the first step in the “invasion-metastasis cascade,” epithelial-to-mesenchymal transition (EMT), and developing antilymphangiogenesis therapies that antagonize lymphatic metastasis. The extracellular matrix-related protein WISP-1 (WNT1-inducible signaling pathway protein-1) stimulates bone remodeling and tumor progression. We have previously reported that WISP-1 promotes OSCC cell migration and lymphangiogenesis induced by vascular endothelial growth factor C (VEGF-C). This investigation sought to determine the role of WISP-1 in regulating EMT in OSCC. Our analysis of oral cancer data from The Cancer Genome Atlas (TCGA) database revealed significant and positive associations between levels of WISP-1 expression and clinical disease stage, as well as regional lymph node metastasis. We also found higher levels of WISP-1 expression in serum samples obtained from patients with OSCC compared with samples from healthy controls. In a series of in vitro investigations, WISP-1 activated EMT signaling via the FAK/ILK/Akt and Snail signaling transduction pathways and downregulated miR-153-3p expression in OSCC cells. Our findings detail how WISP-1 promotes EMT via the miR-153-3p/Snail axis in OSCC cells.

Abstract
Benign and malignant neoplasm of oral cavity is usually presented as swellings or ulcerations of affected tissue. The lesions are broadly categorized as potentially malignant disorders, benign and malignant neoplasm of epithelial and connective tissue origin for the convenience of learning. Neoplasm of oral cavity has a significantly lower incidence. Because of uncommon occurrence of oral neoplasm, retention of diagnostic skills is a challenging task. However, comprehensive understanding on clinical and pathologic details will help in correlating and presenting complaint and assisting in formulation of possible diagnosis. The key for successful therapeutic management depends on achieving right and timely diagnosis.

Abstract
Background: Oral squamous cell carcinoma (OSCC) is one of the most predominant cancers in India. With advances in the field of oncology, a number of therapies have emerged; however, they are minimally effective. Consequently, there is a need to develop safe and effective regimens for the treatment of OSCC. Butein, a tetrahydroxychalcone has been found to exhibit potent antioxidant, anti-inflammatory, and also anti-tumor effects against several cancer types. However, its effect on OSCC is not studied yet. Methods: The effect of butein on the viability, apoptosis, migration and invasion of OSCC cells was evaluated using MTT, colony formation, PI/FACS, live and dead, scratch wound healing, and matrigel invasion assays. Further Western blot analysis was done to evaluate the expression of different proteins involved in the regulation of cancer hallmarks. Results: This is the first report exemplifying the anti-cancer effect of butein against OSCC. Our results showed that butein exhibited potent anti-proliferative, cytotoxic, anti-migratory, and anti-invasive effects in OSCC cells. It suppressed the expression of NF-κB and NF-κB-regulated gene products such as COX-2, survivin and MMP-9 which are involved in the regulation of different processes like proliferation, survival, invasion, and metastasis of OSCC cells. Conclusion Collectively, these results suggest that butein has immense potential in the management of OSCC. Nonetheless, in vivo validation is critical before moving to clinical trials.

Abstract
Objective
Tongue is regarded as one of the common sites of oral squamous cell carcinoma (OSCC). This study aimed to determine the prevalence and clinicopathological profile of OSCC and oral potentially malignant disorders (OPMDs) at the tongue.
Materials and Methods
We retrospectively analyzed clinicopathological characteristics of 208 Thai patients diagnosed with SCC and OPMDs at the tongue in the period from 1996 to 2015. Chi-squared test was used to compare differences between patient’s clinical and histopathological features.
Results
Seventy-eight tongue SCC and 130 tongue OPMD cases were present over the study period. Slight male predominance was found for tongue SCC, while a slight female predominance was present for tongue OPMDs. Both tongue SCC and tongue OPMDs were mostly diagnosed in the old age patients (>40 years old). The majority of tongue SCC and OPMDs occurred at the tip and lateral of the tongue. The most common histologic grading of tongue SCC was well differentiated and no poor differentiation was found in this study. More than a half of tongue OPMDs showed epithelial dysplasia. Both tongue SCC and OPMDs demonstrated no significant correlation between clinical feature and histopathologic diagnosis.
Conclusions
Tongue SCC and OPMDs were particularly found in the elderly population and frequently developed at the tip and lateral of the tongue. Most of tongue OPMDs, particularly all of tongue erythroplakia, exhibited epithelial dysplasia. For dental practitioners, awareness in the early detection and diagnosis of these tongue lesions should be raised.

Abstract
Abstract
Background: Head and neck squamous cell carcinoma (HNSCC) constitutes one of the most common malignancies in the world. The geographic location influences the etiologic factors and site of tumor. Aims and Objectives: The present study was carried out to illustrate the clinicopathologic profiles of HNSCC patients since data regarding these tumors from eastern region of India are scarce. Materials and Methods: A prospective study was undertaken for 2 years in which patients with histologically proven HNSCC were included. The clinicopathologic features of each case were analyzed. Results: A total of 108 cases were included in the study, among which 79 (73.15%) were male and 29 (26.85%) were female. Mean age of the patients was 53.21 (±12.17) years. The most common risk factor was smoking (63 cases, 58.33%) followed by tobacco or betel nut chewing (41 cases, 37.96%). The common patterns of presentation included ulcerated lesion (51 cases, 47.22%), whitish lesion (28 cases, 25.93%), and hoarseness of voice (11 cases, 10.19%). The most common sites involved were buccal mucosa (36 cases, 33.33%) and dorsal surface of the tongue (26 cases, 24.07%). The most common site for exophytic tumors was buccal mucosa (9 out of 23, 39.13%) and that for ulceroproliferative lesions was tongue (9 out of 17, 52.04%). Microscopically, well-differentiated (Grade I) tumors were most common (67 cases, 62.04%) followed by moderately differentiated (Grade II) tumors (38 cases, 35.19%). A statistically significant correlation was obtained between anatomic site and grade of the tumor. Conclusion: Patients of HNSCC from the eastern region of India have distinctive features with regard to macroscopic appearance and microscopic grade of their tumors.

Abstract
Background: Despite the available data on demographic information of oral squamous cell carcinoma (OSCC), the changing trend of histopathologic pattern of OSCC has not conducted yet, in Iran. The aim was to investigate the pattern of histopathologic features of OSCC in Iran by analyzing the patients referred to Cancer Institute, Imam Khomeini Hospital, Tehran University of Medical Sciences, Tehran, Iran, during 2006-2015. Materials and Methods: The study was a retrospective institutional study. The pathology records with the diagnosis of OSCC were retrieved from Iran National Tumor Bank, Cancer Biology Research Center, Cancer Institute of Iran, Tehran University of Medical Sciences, Tehran, Iran, during 2006-2015. The demographic characteristics and histopathologic features were recorded and analyzed for possible trend. Descriptive analysis was used for statistical interpretation. Results: The data showed an increasing number of moderately and poorly differentiated OSCC. Accordingly, higher increasing rate in tumor size and vascular, perineural invasion was detected. Conclusion: On the basis of histopathologic features, moderately differentiated OSCC with increasing rate of tumor size and vascular, perineural invasion was indicated in recent decade. Based on the findings, lower differentiation potentially is compatible with worsen prognosis.
