Kannan B, Pandi C, Pandi A, Jayaseelan VP, Murugan M S, Arumugam P. Altered expression of GLS2 indicates a poor prognosis and correlates with clinicopathological features of oral squamous cell carcinoma. Int J Oral Maxillofac Surg 2024; 53:635-643. [PMID: 38342749 DOI: 10.1016/j.ijom.2024.01.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Revised: 01/24/2024] [Accepted: 01/25/2024] [Indexed: 02/13/2024]
Abstract
Glutamine metabolism, governed by enzymes including glutaminase (GLS1 and GLS2), has a pivotal role in cancer progression. The objective of this study was to determine whether GLS2 transcription levels are associated with oral squamous cell carcinoma (OSCC) when compared to matched adjacent normal tissues. Primary tumour and adjacent normal tissues were collected from 51 OSCC patients, and GLS2 mRNA expression analysis was conducted using real-time qPCR. Additionally, The Cancer Genome Atlas-Head and Neck Squamous Cell Carcinoma (TCGA-HNSCC) dataset was utilized to examine GLS2 expression in relation to clinicopathological features, the prognosis, and tumour immune cell infiltration. A significantly reduced expression of GLS2 mRNA was found in the OSCC tissues when compared to the matched adjacent normal tissue samples (P < 0.001), which aligned with the results from the TCGA-HNSCC dataset and immunohistochemistry. Moreover, GLS2 mRNA expression was associated with clinicopathological features including tumour stage, grade, and human papillomavirus status (all P < 0.05), predicted a poorer prognosis (P = 0.024), and was correlated with tumour immune cell infiltration (all P < 0.05) in head and neck squamous cell carcinoma. Functional pathway analysis indicated its involvement in cell proliferation and metabolic cycles. GLS2 dysregulation is linked to oral cancer, suggesting its potential as a predictive prognostic marker for OSCC. Furthermore, targeting glutaminases via GLS2 may represent a promising therapeutic strategy for OSCC treatment.

Abstract
Introduction Oral cancer is the most persistent, aggressive primary malignant sarcoma that is globally prevalent. Though chemotherapy is the only treatment option, it has not progressed for years to overcome its detrimental side effects. Introducing novel therapeutic techniques to improve effectiveness is the need of the hour. Aim This study aimed to investigate the pro-apoptotic effects of naringin in oral cancer cell lines. Methodology The cell viability of oral cancer cells treated with naringin was measured using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) method. Naringin was given to oral cancer cells (KB-1) in concentrations ranging from 20 to 200 µM/mL for 24 hours. A phase-contrast microscope is used to examine cell morphology changes. Ethidium bromide (EtBr) staining was employed to study nuclear morphological alterations in oral cancer cells. The apoptotic nuclei were viewed under a fluorescent microscope. To determine pro-apoptotic levels, quantitative real-time polymerase chain reaction (PCR) gene expression analysis was performed to evaluate the expression of transforming growth factor-beta (TGF-β), suppressor of mothers against decapentaplegic 2 (SMAD2), tumor necrosis factor alpha (TNFα), and nuclear factor kappa B (NFκB). A scratch wound healing experiment was used to evaluate naringin's anti-migratory properties. Results Our study found that naringin treatment significantly reduced cell viability in oral cancer cells compared to the control group (p < 0.05). In oral cancer cells, we found an inhibitory concentration (IC50) of 125.3 μM/mL. Following treatment, fewer cells were present, and those that were present shrunk and displayed cytoplasmic membrane blebbing. The EtBr staining reveals chromatin condensation and nuclear breakage in treated cells. The study found that naringin downregulates the expression of B-cell leukemia/lymphoma 2 (Bcl-2), TGF-β, SMAD2, TNFα, and NFκB and upregulates the expression of Bcl-2-associated agonist of cell death (BAD), Bcl-2-associated protein X (BAX), and caspase-3. Furthermore, when compared to control cells, naringin significantly reduced cell migration. Naringin treatment significantly promotes apoptosis and inhibits migration by altering the SMAD2 signaling pathway. Conclusion Overall, this study highlights the promising role of naringin as a pro-apoptotic and cytotoxic phytochemical regulating the gene expression of Bcl-2, TGF-β, SMAD2, TNFα, NFκB, BAD, BAX, and caspase-3, thereby treating oral cancer.

Indian J Surg Oncol 2024; 15:218-224. [PMID: 38741652 PMCID: PMC11088589 DOI: 10.1007/s13193-023-01862-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Accepted: 12/06/2023] [Indexed: 05/16/2024] Open
Abstract
Surgical site infections (SSI) following head and neck oncology surgery can lead to significant morbidity and healthcare costs. This cross-sectional study was used to investigate a potential link between pre-operative 25-hydroxy vitamin D deficiency and an increased risk of surgical site infections in patients undergoing oral cavity oncology surgery. This cross-sectional study was conducted at a tertiary center in northwestern India from May 2022 to May 2023. Patients scheduled to undergo oral cavity oncology surgery during this period were eligible for inclusion. Patients with complete pre-operative 25-hydroxy vitamin D levels and documented post-operative wound infection status were included in the analysis. A total of 85 patients who underwent oral cavity oncology surgery were included in the study. Among them, 30.58% (26 patients) had pre-operative vitamin D deficiency, The overall incidence of surgical site infection (SSI) was 36.47% (31 patients). Among the patients with pre-operative vitamin D deficiency, 23 (88.5%) developed surgical site infections. Finally, pre-operative levels of 25-hydroxy vitamin D, pre-operative poor oral hygiene, and low albumin were confirmed as statistically significant independent predictors of SSI. After doing multivariate analysis, vitamin D deficiency was found to be a significant predictor of post-op wound infection [adjusted odds ratio - 0.71 (95% CI 0.61-0.82); p value < 0.001]. This study highlights the significant association between pre-operative 25-hydroxy vitamin D deficiency and an increased risk of surgical site infections in patients. Vitamin D plays a crucial role in modulating the immune response, promoting antimicrobial peptides, and enhancing wound healing. These findings support the importance of assessing and addressing vitamin D deficiency in patients scheduled for oral cavity oncology surgery to potentially reduce the incidence of SSIs.

Abstract
A prospective cross-sectional study was conducted to correlate clinically, radiologically, and pathologically the mandibular invasion in carcinoma bucco-alveolar complex. All biopsy-proven oral cavity cancer cases (64 patients) were assessed clinically and radiologically for involvement of the mandible. Preoperative clinicoradiological findings were compared with postoperative histopathological findings. In our study, oral cancer was 4 times more prevalent in males as compared to females and clinical evaluation was found to be highly sensitive in predicting mandibular invasion. Orthopantomogram showed sensitivity of 66.6% and specificity of 100%. CT scan showed sensitivity of 100% and specificity of 46% whereas MRI showed sensitivity of 54.5% and a specificity of 96%. MRI correlates well with final histopathology in predicting size of tumor. Prevalence of bony invasion in carcinoma oral cavity was 18%. We noted an inverse relation with tumor differentiation and mandibular invasion, and none of the verrucous carcinoma lesions showed mandibular invasion. Association of clinical T and N staging with postoperative histopathology was found to be statistically significant. Despite recent advances in molecular biology, radiological techniques, and newer modalities like visual surgical planning, exact measurement of bone invasion is still challenging. At present, CT scan and MRI along with clinical evaluation are widely used to evaluate mandibular invasion in carcinoma oral cavity, and all these are complementary to each other. The recent progress in tissue engineering technologies and stem cell biology has significantly promoted the development of regenerative reconstruction of jawbone defects.

Abstract
(1) Background: To compare oncologic outcomes of South Asian (SA) patients treated for oral squamous cell carcinoma (OSCC) to the general population. (2) Methods: Adult patients who underwent surgical resection of OSCC +/- adjuvant treatment between 2009 and 2022 (N = 697) at a regional cancer centre in Canada were included. SA patients, identified using a validated method, were compared to non-SA patients. Kaplan-Meier methods were used to compare the primary outcomes, disease-specific survival (DSS) and recurrence-free survival (RFS) across baseline univariate characteristics, including betel nut consumption. Median follow-up time was 36.4 months. Cox proportional hazard models were used to identify independent predictors of survival with significance set at p < 0.05. (3) Results: SA patients (9% of cohort, N = 64) were significantly younger and had lower rates of smoking and alcohol consumption compared to non-SA patients (p < 0.05). SA patients had a two-fold higher risk of recurrence and significantly worse disease-specific survival, even after adjusting for stage and high-risk features [RFS: HR 2.01 (1.28-3.14), DSS: HR 1.79 (1.12-2.88)]. The consumption of betel nut was not associated with outcomes. (4) Conclusions: SA patients had significantly worse oncologic outcomes, even after controlling for known predictors of poor prognosis. These findings are novel and can inform personalized treatment decisions and influence public health policies when managing patients with different ethnic backgrounds.

Abstract
Background and Aim Oxidative stress markers have been firmly established as elevated in oral squamous cell carcinomas (OSCCs). These markers play a crucial role in the pathogenic mechanism underlying the accumulation of advanced glycation end products (AGEs) and their respective receptors. The primary objective of this study is to discern and compare the levels of receptors of AGEs (RAGEs) within tissue samples from patients diagnosed with oral submucous fibrosis (OSMF) at varying stages, oral leukoplakia at various stages, and OSCC. Materials and Methods A cross-sectional investigation was conducted, enrolling a total of 49 patients, distributed across three distinct groups. Tissue samples were meticulously collected from the aforementioned patient groups. Subsequently, these samples underwent a process of homogenization and centrifugation. The supernatant obtained was subjected to enzyme-linked immunosorbent assay analysis to precisely determine the concentration of RAGE. Results The concentration of RAGEs was found to be significantly higher at various stages of OSMF when compared to the reference group of OSCC (P < 0.05). This difference was statistically significant, indicating a substantial association. In contrast, the levels of RAGE in patients with hyperkeratosis accompanied by epithelial dysplasia at various stages were observed to be lower than those in the OSCC group, with the difference in concentration being statistically insignificant (P > 0.05). Conclusion This comprehensive study has provided compelling evidence demonstrating the heightened levels of RAGE in OSMF when compared to OSCC. These findings collectively suggest the potential utility of anti-RAGE interventions as a promising avenue for novel therapeutic strategies in potentially malignant disorders such as OSMF.

Abstract
Introduction Tumor necrosis factor α (TNF-α) is known to be associated with chronic inflammation, and its expression has been shown to increase in advanced cancers. Chronic inflammation is a characteristic feature of oral submucous fibrosis (OSMF), which is a potentially malignant disorder (PMD). Squamous cell carcinoma (SCC) is associated with considerable mortality and morbidity and an early detection or monitoring would greatly help in achieving an effective cure. TNF-α was thus evaluated for use as a biomarker in the present study according to the stage of OSMF and histological grade of SCC in the oral cavity and oropharynx. Methods This study included 45 patients divided into 3 groups-OSMF group, SCC group and control group-each comprising 15 participants. Saliva samples were collected from each patient, and salivary TNF-α levels were estimated using an ELISA kit. Results Statistical analysis revealed no significant differences in TNF-α levels among the OSMF, SCC and control groups; however, there was an increase in the salivary TNF-α level in patients with stage 3 disease according to the clinical stage of OSMF, for which the p value was 0.027. Discussion An increase in the TNF-α concentration with increasing clinical stage suggested a role for TNF-α in the spread of OSMF involvement in anatomical structures of the oral cavity and oropharynx. No significant difference in salivary TNF-α levels was noted among the OSMF, SCC and control groups. Conclusion The study showed a positive correlation of TNF-α with increasing stages of OSMF but was not a reliable biomarker in the categorization of the same.

Prevalence of Epstein Barr Virus and Herpes Simplex Virus Among Human Papillomavirus Negative Oral Cancer Patients: A Cross-Sectional Study from South India. Indian J Otolaryngol Head Neck Surg 2024; 76:414-421. [PMID: 38440516 PMCID: PMC10908691 DOI: 10.1007/s12070-023-04174-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Accepted: 08/21/2023] [Indexed: 03/06/2024] Open
Abstract
The high incidence of oral carcinomas is due to its multifactorial etiology and the presence of various risk factors. Human Papillomavirus (HPV) has a proven role in the pathogenesis of oral carcinomas, but in the recent times there has been an increasing incidence of oral cancers who are negative for HPV infection. Also, these patients are non-smokers and non-drinkers so it could be speculated that these oral cancers are due to some other etiological factor probably of other viral infections. Therefore, this study examined the prevalence of Epstein Barr Virus (EBV) and Herpes Simplex Virus (HSV) among oral cancer patients. This cross-sectional study was conducted from January 2019 to June 2020. Biopsy samples from 47 newly diagnosed untreated patients with oral malignancies were collected along with their demographic and clinicopathological information. DNA extracted from the biopsies was processed for nested PCR for the detection of EBV and HSV. All the samples tested negative for HPV and HSV infection. Nested PCR detected 29 cases (70.7%) to be positive for EBV. The non-cancerous adjacent tissues also were negative for HPV, EBV and HSV. The prevalence of EBV was found to be more in males (62.1%) and the highest number of cases was of the left buccal mucosa compromising 34% of the total cases. From the present study it can be concluded that EBV but not HSV infection is associated with an increased risk of developing oral cancers. Although, 70.7% of the patients were found to be positive for EBV whether the viral infection played any role in the driving the malignancy needs to be further elucidated.

Abstract
Background Oral cancer is a significant global health issue, with prevention and early detection being pivotal for improved outcomes. This study investigates the impact of cultural and socioeconomic factors on oral cancer prevention behaviors, screening participation, and treatment outcomes. Materials and Methods A cross-sectional study design was employed, involving a sample size of 1,000 participants. Participants were recruited through stratified sampling to ensure cultural and socioeconomic diversity. Statistical analyses, including logistic regression, were used to explore associations between factors and outcomes. Results The study revealed multifaceted influences of cultural and socioeconomic factors on oral cancer-related aspects. Cultural factors significantly influenced prevention behaviors, with participants from certain cultural backgrounds exhibiting higher rates of tobacco use and lower rates of dietary adherence). Socioeconomic status played a role in screening uptake, with individuals from lower income brackets less likely to undergo regular screenings. Conclusion Cultural and socioeconomic factors have a substantial influence on oral cancer prevention behaviors, screening participation, and treatment outcomes.

Abstract
The use of tobacco products is one of the established contributors toward the development and spread of oral cancer. Additionally, recent research has indicated oral microbiome, infections with Human papilloma virus (HPV), Epstein-Barr virus (EBV), Candida as significant contributing factors to this disease along with lifestyle habits. Deregulation of cellular pathways envisaging metabolism, transcription, translation, and epigenetics caused by these risk factors either individually or in unison is manifold, resulting in the increased risk of oral cancer. Globally, this cancer continues to exist as one of the major causes of cancer-related mortalities; the numbers in the developing South Asian countries clearly indicate yearly escalation. This review encompasses the variety of genetic modifications, including adduct formation, mutation (duplication, deletion, and translocation), and epigenetic changes evident in oral squamous cell carcinoma (OSCC). In addition, it highlights the interference caused by tobacco products in Wnt signaling, PI3K/Akt/mTOR, JAK-STAT, and other important pathways. The information provided also ensures a comprehensive and critical revisit to non-tobacco-induced OSCC. Extensive literature survey and analysis has been conducted to generate the chromosome maps specifically highlighting OSCC-related mutations with the potential to act as spectacles for the early diagnosis and targeted treatment of this disease cancer.

Abstract
Oral cancer, a disfiguring and life threatening cancer, significantly affects the day-to-day life of not only the patients but also their family members in terms of life quality and financial burden. India records higher incidence of oral cancer every year and is mainly due to the habituation of tobacco products and alcohol abuse. Delay in diagnosis and treatment influences India's higher incidence of oral cancer, where annually 50,000-60,000 oral carcinoma cases are reported. 7,12-dimethylbenz(a)anthracene (DMBA)-induced cancer in the oral cavity mimics human oral cancer in histopathological, molecular, and morphological aspects, and thus, by using this paradigm, the tumor inhibiting efficacy of medicinal plants or herbs and their components is scientifically validated. Ursolic acid, due to its multiple pharmacological effects, has been attracted, in recent years, for chemoprevention research program. Though, ursolic acid has been shown to have beneficial effects, its poor water solubility and bioavailability hinder to exert its 100% efficacy. Therefore, ursolic acid is encapsulated in either natural or synthetic polymers to enhance its therapeutic efficacy. Chitosan is one of the natural polymers that have been employed in the synthesis of nanoparticles to improve the drug efficacy. The present study has thus chosen ursolic acid-loaded chitosan nanoparticles (UACNP) to assess its anticancer efficacy in the DMBA-induced oral carcinoma. The anticancer efficacy of UACNP in experimental oral carcinogenesis was assessed by employing the status of oxidative markers and detoxification cascade as an end point. DMBA-induced abnormalities in the status of oxidative markers and detoxification cascade were reversed by ursolic acid-loaded chitosan nanoparticles. The tumor inhibiting or suppressing effect of UACNP is thus explored in experimental oral carcinogenesis.

Cancers (Basel) 2023; 15:3077. [PMID: 37370688 DOI: 10.3390/cancers15123077] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2023] [Revised: 05/30/2023] [Accepted: 06/01/2023] [Indexed: 06/29/2023] Open
Abstract
Even if the relationship between immunosuppression and increased incidence of systemic cancers is well known, there is less awareness about the risk of developing oral cancer in immunosuppressed patients. The aim of this review was to evaluate the association between immunosuppression and the development of oral cancer. Two authors independently and, in duplicate, conducted a systematic literature review of international journals and electronic databases (MEDLINE via OVID, Scopus, and Web of Science) from their inception to 28 April 2023. The assessment of risk of bias and overall quality of evidence was performed using the Newcastle-Ottawa Scale and GRADE system. A total of 2843 articles was identified, of which 44 met the inclusion criteria and were included in either the qualitative or quantitative analysis. The methodological quality of the included studies was generally high or moderate. The quantitative analysis of the studies revealed that immunosuppression should be considered a risk factor for the development of oral cancer, with a percentage of increased risk ranging from 0.2% to 1% (95% CI: 0.2% to 1.4%). In conclusion, the results suggest that a constant and accurate follow-up should be reserved for all immunosuppressed patients as a crucial strategy to intercept lesions that have an increased potential to evolve into oral cancer.

Abstract
Background Carcinoma of buccal mucosa forms a sizeable percentage of the diagnosed oral cavity cancers in India. There is limited data on elective treatment of the contralateral neck for well-lateralized carcinoma with no involved nodes in the contralateral neck. We conducted this study to compare locoregional control in patients treated with unilateral vs. bilateral neck irradiation. Materials and methods 48 patients with carcinoma of buccal mucosa were selected. Patients were divided into unilateral and bilateral arms based on radiation treatment of the ipsilateral or bilateral neck. All patients received adjuvant radiation with Cobalt 60 unit. Patient-specific and follow-up data were collected from records and dosimetric data from treatment planning system (TPS). Chi-square and unpaired t-test was used to compare data between arms and Kaplan Meier plot; Cox regression was used for survival analysis. Results After a median follow-up of 23 months, 15 (31.3%) patients had developed disease recurrence, 8 and 7 in the unilateral and bilateral arms, respectively (p = 0.591). There was no contralateral neck failure during the follow-up period. The 2-year disease-free survival was 68.2% and 72.2% in the unilateral and bilateral arms, respectively. Among risk factors for disease recurrence, depth of invasion (DOI), delay in starting radiation and planning target volume (PTV) coverage were significant contributing factors. Cox multivariate regression suggested DOI and delay in starting radiation to be significant prognostic factors for disease-free survival (DFS). Conclusion Bilateral neck radiation does not provide any advantage over ipsilateral neck radiation for properly selected well lateralized buccal mucosal squamous cell carcinoma. Ipsilateral neck radiation facilitates better sparing of organs at risk.

Abstract
BACKGROUND The Objective of this study was estimation of Temporomandibular joint dysfunction in oral cancer survivors. METHODS The hundred patients with oral cancer who had undergone radiotherapy or chemotherapy were randomly selected as per inclusion criteria. Range of motion of temporomandibular joint(TMJ), visual analogue scale (VAS), Manual muscle testing (MMT), Auscultation test, Chvostek test and swelling over orofacial muscles were used as the Outcome measures. RESULTS The findings of this study revealed that the Temporomandibular joint was significantly dysfunctional. The group analysis demonstrated statistically significant impairments in all the Outcome measures. VAS (p<0.0001), ROM for all four motions (p<0.0001), Manual muscle testing (p<0.0001), Provocation test (52%), Auscultation test (92%), Chvostek Test (4%), and swelling (56%) were all shown significant dysfunction of TMJ. CONCLUSION This study showed that pain was increased during activity than at rest based on the findings of VAS pain rating scale. It was found that the range of motion of TMJ was significantly reduced; however muscular strength was minimally affected. Majority of survivors were tested positive for the provocation test and auscultation test and few for Chvostek test which indicated the involvement of facial nerve.

Abstract
Early detection is a major step in the success of cancer therapy. Histopathology report is considered as the gold standard in the formulation of management protocol of any malignancy worldwide. But unfortunately, there is a delay in the detection of oral cancer very often due to inconclusive histopathology reports. The main reason behind it is obtaining a biopsy specimen from the non-representative area of the lesion. A hospital-based evaluation of the role of Toluidine Blue dye, used as an adjunctive method prior to biopsy was conducted in a tertiary care hospital on 200 patients presenting with oral lesions persistent for more than 3 weeks. The participants were divided into two equal groups by alternate sampling. In one group biopsy was taken by clinical judgment and in others, Toluidine Blue was used prior to obtaining a biopsy to decide the area to be biopsied. Data was collected using a predesigned proforma and was analyzed with the help of SPSS version 20. Results in two groups were compared with respect to sensitivity, specificity, positive and negative predictive values, false positive and false negative percentages. The Sensitivity, Specificity, Positive Predictive Value and Negative Predictive Value of wedge biopsy without staining were 73.68, 58.14, 70.00, and 62.50% respectively. These values were 95.08, 82.05, 89.23, and 91.43% respectively when Toluidine Blue staining was done as an adjunctive before the biopsy procedure. These results indicate the promising role of Toluidine blue staining before the biopsy to diagnose oral malignancy more efficiently than obtaining biopsy specimens on clinical assessment only and in avoiding the delay in initiating the treatment in case of oral malignant lesions.

Abstract
Context Areca nut, used alone or in combination with tobacco, contributes to the high oral cancer burden in India. Used widely by adolescents, who perceive it as a harmless substance, areca nut is addictive and considered a precursor to tobacco use. Given its serious implications for addictiveness and physical health, urgent preventive interventions for areca nut use are required in India and South-East Asia. Studies examining the role of health behavior theory in explaining and predicting areca nut use and for development of its prevention among adolescents are scarce. Aim This study explored the role of the components of Theory of Planned Behavior (TPB) such as attitudes, subjective norms, perceived behavioral control, and intention in predicting areca nut use among adolescents. Settings and Design Observational study with cross-sectional design conducted with 1884 male and female adolescents attending low-income schools in Mumbai, India. Methods and Material Self-administered surveys were used to gather data on age, gender, behavioral factors and areca nut use. Statistical Analysis Used Chi-square and Mann Whitney test for bivariate and logistic regression for multivariate analysis. Results Around 27.2% of 1884 participants were areca nut users. The mean age of users was 13.75 years. Intention-to-use and perceived behavioral control were statistically significant predictors of actual areca nut use (p<0.001). The components of TPB such as attitude, perceived subjective social norms, and perceived behavioral control had a statistically significant effect on the intention-to-use areca nut (p<0.05). Conclusion This exploratory study indicates that constructs from TPB could help us understand and predict areca nut use. However, more rigorous future research is required to generate insights that help craft effective theory-based behavioral interventions for areca nut prevention and cessation in adolescents.

Abstract
DNA methylation is a physiologically epigenetic alteration that happens when a methyl group is introduced to a CpG dinucleotide in the gene-regulating sequence of DNA. However, the majority of oral cancers have a well-defined precancerous stage; there are few clinical and morphological parameters for detecting and signalling the progression of precancerous to malignant tumours. DNA methylation forms are dynamic and reversible, allowing them to adjust to environmental or therapeutic changes. We did an extensive investigation to compile the data supporting aberrant DNA methylation forms as a possible biomarker for prediction. According to two longitudinal studies, p16 hypermethylation was considerably higher in precancerous lesions that progressed to cancer than in lesions that shrank. Most of the studies examined for this study were tiny cross-sectional research with scant validation and inadequately specified control groups. Existing evidence suggests that DNA methylation sequences can be relevant as a diagnostic biomarker for OPS development; however, sample size and research design restrictions make it difficult to draw definitive conclusions. Strong studies, including extensive epigenome-wide methylation scans of OPS with longitudinal monitoring, are necessary in this study in order to corroborate the recently discovered signals and discover new risk loci and disease progression molecular pathways.

Abstract
Tripartite motif (TRIM) protein family proteins contain more than 80 members in humans, and most of these proteins exhibit E3 ubiquitin ligase activity mediated through a RING finger domain. Their biological functions are very complex, and they perform diverse functions in cell evolution processes, such as intracellular signaling, development, apoptosis, protein quality control, innate immunity, autophagy, and carcinogenesis. Tripartite motif-containing protein 2 (TRIM2), a member of the TRIM superfamily, is an 81 kDa multidomain protein, also known as CMT2R or RNF86, located at 4q31.3. TRIM2 functions as an E3 ubiquitin ligase. Current studies have shown that TRIM2 can play roles in neuroprotection, neuronal rapid ischemic tolerance, antiviral responses, neurological diseases, etc. Moreover, based on some studies in tumors, TRIM2 regulates tumor proliferation, migration, invasion, apoptosis, and drug resistance through different mechanisms and plays a critical role in tumor occurrence and development. This review is aimed at providing a systematic and comprehensive summary of research on TRIM2 and at exploring the potential role of TRIM2 as a biomarker and therapeutic target in many kinds of human diseases.

Abstract
Oral cancer is highly prevalent in the Indian subcontinent. With the increasing immigration of Indians to Australia, a potential rise in oral cancer cases can be expected if they continue engaging in oral cancer risk practices. Unfortunately, little is known on this topic in the Australian context. This study aimed to generate new insights into this area by examining Indian immigrants’ knowledge, attitudes and practices regarding oral cancer in Australia and their perceived role of general practitioners in raising oral cancer awareness. Exploring these aspects could determine the oral cancer risk behaviours of Indians in Australia along with any contributing factors which could help identify potential preventative strategies. A cross-sectional survey was undertaken of 164 Indians across Australia. Data were analysed using SPSS software with descriptive statistics. Respondents had varying levels of knowledge about oral cancer (mean total score 61%), particularly around risk factors such as alcohol and areca nut use as well as oral cancer-related signs/symptoms. The majority (87.7%) had not received any information about oral cancer in a health care setting but were receptive (71–90%) to general practitioners playing a more active role in this area. Respondents were engaging in positive preventative oral health care though few were currently (6.7%) or previously (14.7%) chewing tobacco preparations. Further research is needed through larger studies to confirm the study findings and inform the development of culturally tailored strategies particularly involving general practitioners, to raise oral cancer awareness and provide early screening for Indian immigrants.

Abstract
Background Focal tissue overgrowths on the gingiva and edentulous alveolar ridge are occasionally perplexing to periodontists, owing to the wide variety of differential diagnoses that may be responsible. As such, biopsy and microscopy are often required to establish a definitive diagnosis. The present study aimed to retrospectively evaluate focal gingival and alveolar ridge overgrowths at a single institution in Saudi Arabia. Materials and Methods Histopathology reports and slides from patients presenting to King Saud University Hospital between 1984 and 2016, particularly those with focal gingival enlargements other than those due to gingivitis and periodontitis, were collected and analyzed based on age, sex, and location. Results A total of 624 patient records were evaluated, with a mean age of 35 years (range, 1 week–91 years), peak incidence in the third decade of life, male-to-female ratio of 1:1.4, and a slightly higher prevalence of lesions in the mandible. The majority (88%) of the lesions were reactive or hyperplastic, followed by malignant (10%) and benign (2%) tumors. A total of 24 distinct histological entities were diagnosed across the three groups. The most common histologically diagnosed lesions were pyogenic granulomas (38%), fibromas (33%), peripheral ossifying fibromas (9%), squamous cell carcinomas (7%), peripheral giant cell granulomas (6%), neurofibromas (1%), and non-Hodgkin lymphomas (1%). Conclusion Similar to what has been reported by most previous studies, reactive hyperplastic lesions were the most prevalent focal overgrowths found in the gingival and alveolar mucosae. Carcinomas at these sites, however, may be an understated but significant clinical and epidemiological problem in Saudi Arabia. Gingival and alveolar ridge lumps can serve as a nexus for cooperation between periodontologists and oral pathologists to improve diagnosis, disease classification, and patient management.

Abstract
Early detection and complete resection of oral squamous cell carcinoma (OSCC) are crucial to improving patient survival and prognosis. However, specifically targeted imaging probes for OSCC detection are limited. This study aimed to synthesize a novel near-infrared fluorescence (NIRF) probe for precision detection and fluorescence image-guided surgery in OSCC. Bioinformatics data indicated that glucose transporter 1 (GLUT1) is highly expressed in patients with OSCC. We demonstrated high and specific GLUT1 expression upon immunohistochemical staining of samples from 20 patients with OSCC. The specific expression of GLUT1 was further validated in both human OSCC cell lines and OSCC tumor xenografts. Based on these findings, the GLUT1 inhibitor WZB117 was utilized to synthesize a novel NIRF imaging probe, WZB117-IR820. The fluorescence molecular imaging data revealed that WZB117-IR820 could specifically bind to the tumor areas in an orthotopic OSCC mouse model after intravenous injection and could be further applied for precision fluorescence image-guided surgery with no residual tumor in the orthotopic CAL27-fLUC mouse tumor model. For further clinical translational application in patients with OSCC, precise delineation of OSCC tumor areas was achieved following topical application of the WZB117-IR820 imaging probe and was validated by histopathological and immunohistochemical analyses. In conclusion, we synthesized a novel fluorescent imaging probe, WZB117-IR820, which has potential clinical applications for early detection and fluorescence image-guided surgery in OSCC with no observable toxicity.

Tumor necrosis factor-α induced protein 8 (TNFAIP8/TIPE) family is differentially expressed in oral cancer and regulates tumorigenesis through Akt/mTOR/STAT3 signaling cascade. Life Sci 2021; 287:120118. [PMID: 34740574 DOI: 10.1016/j.lfs.2021.120118] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2021] [Revised: 10/23/2021] [Accepted: 10/29/2021] [Indexed: 11/24/2022]
Abstract
BACKGROUND Highest incidence of oral cancer is reported in India with reduced survival rate in the advanced stages due to lack of effective biomarkers. Therefore, it is essential to develop novel biomarkers for the better management of this disease. In the current study, TNFAIP8/TIPE protein family comprising of four proteins is explored for its role in oral cancer. METHODS IHC analysis of oral cancer TMA and Western blot analysis of tobacco treated oral cancer cells were performed to determine the differential expression of TIPE proteins in oral cancer. Further, CRISPR/Cas9-mediated gene editing was done to generate TIPE proteins' knockouts and MTT, colony formation, wound healing, cell cycle and Western blot analysis were performed to determine the effect of gene knockouts on various cancer hallmarks and the associated molecular targets of TIPE proteins. RESULTS AND DISCUSSION IHC results revealed that expression of TIPE, TIPE2 and TIPE3 were upregulated and TIPE1 was downregulated in oral cancer tissues compared to normal tissues. Similar results were observed upon treating oral cancer cells with tobacco carcinogens. Furthermore, knockout of TIPE or TIPE2 or TIPE3 significantly reduced the survival, proliferation, colony formation and migration of oral cancer cells whereas knockout of TIPE1 had an opposite effect. Further, TIPE, TIPE2 and TIPE3 knockout-mediated inhibition of proliferation was associated with inhibition of cell cycle progression at S or G2/M phases, and downregulation of proteins involved in cancer progression. We found that TIPE, TIPE1 and TIPE2 proteins regulate oral cancer progression through modulation of Akt/mTOR signaling cascade, whereas TIPE3 acts through an Akt-independent mTOR/STAT3 pathway. CONCLUSION Collectively, the TIPE proteins were proved to play significant roles in the progression of oral cancer thus warranting research and clinic attention for their therapeutic and prognostic values and raising the importance of specific targeting of TIPE proteins in cancer treatment.

Abstract
OBJECTIVE Oral cancer is widespread in South Asia, particularly India. In Australia, Indians are one of the fastest-growing communities. This study aimed to explore the oral cancer-related knowledge, attitudes and practices of Indian immigrants in Australia. METHODS Fourteen semi-structured interviews were conducted with Indian immigrants residing across New South Wales and Victoria. Purposive and snowball sampling were used for recruitment. Data were analysed through a directed content analysis approach. RESULTS All participants were knowledgeable of oral cancer risks associated with tobacco and alcohol, but few were familiar with the harmful effects of areca nut preparations. Varied attitudes were evident with most participants acknowledging the importance of oral cancer check-ups, yet very few followed this practice. All participants admitted engaging in oral cancer risk practices including areca nut use at least once or more in their lifetime. CONCLUSION Oral cancer risk practices are common among Indian immigrants in Australia who possess limited knowledge with varying attitudes in this area. Implications for public health: Preventative strategies are needed to limit the use of oral cancer risk products among Indian immigrants. General practitioners and community organisations can play a key role in raising awareness in this area.

Abstract
BACKGROUND In Australia, Indian immigrants are one of the fastest-growing communities. Since oral cancer is widespread in India, the indulgence of Indians in customs of areca (betel) nut use in Australia may be linked to the recent rise in oral cancer cases. Since GPs (general practitioners) are primary healthcare providers, it is pivotal to ensure the oral cancer awareness of GPs. This study aimed to explore oral cancer risk-related knowledge, beliefs, and clinical practices of GPs in Australia. METHODS Fourteen semi-structured interviews were conducted with GPs practicing across New South Wales and Victoria. Purposive and snowball sampling were used for recruitment. Data were analysed through a directed content analysis approach. RESULTS All GPs were knowledgeable of major oral cancer causative factors including tobacco and alcohol, but some had limited understanding about the risks associated with areca nut preparations. Positive attitudes were evident, with all participants acknowledging the importance of oral cancer risk assessment. Most GPs recalled not performing oral cancer routine check-ups. CONCLUSION GPs presented good oral cancer knowledge except for emerging risk factors such as areca nut use. Varied beliefs and inconsistent clinical practices relating to oral cancer screening is concerning. Accessible oral cancer training around emerging risk factors may benefit GPs.

Abstract
PURPOSE Oral cancer (OC) is the leading cancer in 25% of Indian cancer registries, and 80% of OCs are diagnosed in advanced stages. OC screening is a topic of debate. Studies from other countries have used a variety of study designs as OC screening strategies. There are not many studies from India on strategic screening, and there is a need to review the literature to provide insights and knowledge about screening programs. The purpose of this narrative review is to present broad epidemiologic evidence on the OC burden in India, to discuss and summarize the currently available evidence for OC screening strategies, and to highlight a feasible opportunistic screening strategy for addressing OC burden in India. METHODS Medline and EMBASE were used to identify articles. Data from GLOBOCAN and government reports were obtained from websites. As many key concepts and divergent views cannot be addressed with a single research question, a narrative review was considered appropriate, but to ensure a comprehensive literature search, a systematic review search strategy was used. RESULTS OC rates are rising more rapidly in India than projected. Wide variations in OC incidence within India reflect regional diversity of risk factors. Studies abroad have demonstrated the feasibility of opportunistic screening of oral potentially malignant disorders by dentists; however, although recommendations exist in India, no studies of opportunistic screening by dentists have been reported. CONCLUSION The projected major increases in the OC burden necessitate an OC screening program; opportunistic screening of high-risk groups by dentists using oral visual examination is recommended as a cost-effective strategy. As a way forward, a pilot project to assess the feasibility of regional opportunistic screening is in progress.

Abstract
OBJECTIVE The oral and oropharyngeal squamous cell carcinoma (OOSCC) accounts for 90-95% of tumours in the oral cavity. Single nucleotide polymorphism (SNP) in the coding region of PON1, tumour necrosis factor-alpha (TNF-α) and transforming growth factor-beta (TGF-β) have been associated with to development of different cancers. Our aim was to investigate the prognostic value of PON1 (rs854560 and rs662), TNF-α (rs1800629 and rs361525) and TGF-β (rs1800469) SNPs in OOSCC. MATERIALS AND METHODS We genotyped 163 OOSCC patients and 146 patients from group of control for PON1 (rs854560 and rs662), TNF-α (rs1800629 and rs361525) and TGF-β (rs1800469) SNPs by real-time polymerase chain reaction (PCR). RESULTS TNF-α (rs1800629) GG genotype was significantly more frequent in intraoral lesions and clinical stages III and IV, while the polymorphic AA genotype in lip lesion and clinical stages I and II. Moreover, TGF-β (rs1800469) AG and AA genotypes were significantly more frequent in larger tumours (T3 e T4). TNF-α (rs1800629) AG genotype had poor survival and patients carrying the PON1 (rs662) TT genotype tended to poor survival. CONCLUSIONS Results suggest that the rs1800629 and rs1800469 could exert influence in the more aggressive behaviour of OOSCC and the genotypes AG of rs1800629, and TT of rs662 could be markers with prognostic value in OOSCC.

Abstract
Introduction Nodal metastasis reduces the survival by 50% in head-and-neck squamous cell carcinomas. The presence of nodal extension/extracapsular spread (ECS) further reduces survival. Current literature favors a selective level IIb sparing neck dissection in clinically N0 neck. Studies have evaluated the role of primary tumour size, number of lymph nodes, and depth of invasion (DOI) with the occurrence of extranodal extension (ENE). Patients and Methods Patients were retrospectively reviewed who presented with oral cavity carcinomas and clinically N0 neck. Relationship was sought between tumour site, size, histological grading, DOI, and the occurrence of level IIb metastasis and ECS. A P < 0.05 was considered statistically significant. Results The relationship showed insignificant correlation with P values (0.6643, 0.6704, 0.6779, and 0.6779) between site, size, grading, DOI, and level IIb and ENE. Discussion Previous studies have shown DOI >5 mm and lymph node size 15 mm and multiple lymph nodes predict ECS. DOI and primary site with more than 20% for occult metastasis predicts elective neck treatment. However, in our study, no correlation was found between primary tumour characteristics and ECS or level IIb metastasis. Elective neck dissection is the standard surgical protocol from both diagnostic and therapeutic viewpoints. The only criterion for level IIb dissection is concomitant presence of level IIa involvement intraoperatively. Since ENE can occur early in the disease process, elective neck dissection remains the standard of care.

Abstract
Smokeless tobacco use among Indian women is increasing despite prevention efforts. Evolutionary theories suggest that reproductive-aged women should be more concerned about immediate threats to reproduction than threats to survival occurring late in life. This study therefore compared an anti-tobacco intervention that emphasized near-term reproductive harms to one involving general harms occurring later in life. Scheduled Tribal women (N = 92) from Karnataka, India participated in this study. At baseline, women reported tobacco use and knowledge of harms, provided a saliva sample to assess use, and randomly viewed either a general harms presentation (GHP) or reproductive harms presentation (RHP). At followup, women reported their use, knowledge of harms and intentions to quit, and provided another saliva sample. At baseline, participants were aware of general harms but not reproductive harms. Both interventions increased knowledge of harms. Women in the RHP condition did not list more harms than women in the GHP condition, however, and the RHP was not more effective in reducing tobacco use than the GHP. In the RHP condition fetal health was particularly salient. In the GHP condition, oral health was highly salient, aligning with the local disease ecology and research on tobacco use and attractiveness.

[PMID: 30892161 DOI: 10.2174/1389450120666190319125734] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2018] [Revised: 12/31/2018] [Accepted: 03/11/2019] [Indexed: 12/29/2022]
Abstract
Oral Cancer (OC) is a serious and growing problem which constitutes a huge burden on people in more and less economically developed countries alike. The scenario is clearly depicted from the increase in the expected number of new cases in the US diagnosed with OC from 49,670 people in 2016, to 49,750 cases in 2017. The situation is even more alarming in India, with 75,000 to 80,000 new cases being reported every year, thus making it the OC capital of the world. Leukoplakia, erythroplakia, oral lichen planus, oral submucous fibrosis, discoid lupus erythmatosus, hereditary disorders such as dyskeratosis congenital and epidermolisys bullosa are highlighted by WHO expert working group as the predisposing factors increasing the risk of OC. Consumption of tobacco and alcohol, genetic factors, and human papilloma virus are assigned as the factors contributing to the aetiology of OC. On the other hand, pathogenesis of OC involves not only apoptosis but also pain, inflammation and oxidative stress. Inspite of current treatment options (surgery, radiotherapy, and chemotherapy), OC is often associated with recurrence and formation of secondary primary tumours resulting in poor overall survival rates (∼50%). The intervention of nano technology-based drug delivery systems as therapeutics for cancers is often viewed as a cutting edge for technologists. Though ample literature on the usefulness of nano-coutured cancer therapeutics, rarely any product is in pipeline. Yet, despite all the hype about nanotechnology, there are few ongoing trials. This review discusses the current and future trends of nano-based drug delivery for the treatment of OC.

Abstract
This review traces the growing burden of cancer in India from antiquity. We searched PubMed, Internet Archive, the British Library, and several other sources for information on cancer in Indian history. Paleopathology studies from Indus Valley Civilization sites do not reveal any malignancy. Cancer-like diseases and remedies are mentioned in the ancient Ayurveda and Siddha manuscripts from India. Cancer was rarely mentioned in the medieval literature from India. Cancer case reports from India began in the 17th century. Between 1860 and 1910, several audits and cancer case series were published by Indian Medical Service doctors across India. The landmark study by Nath and Grewal used autopsy, pathology, and clinical data between 1917 and 1932 from various medical college hospitals across India to confirm that cancer was a common cause of death in middle-aged and elderly Indians. India’s cancer burden was apparently low as a result of the short life expectancy of the natives in those times. In 1946, a national committee on health reforms recommended the creation of sufficient facilities to diagnose and manage the increasing cancer burden in all Indian states. Trends from the Mumbai population-based cancer registry revealed a four-fold increase in patients with cancer from 1964 to 2012. Depending on the epidemiologic transition level, wide interstate variation in cancer burden is found in India. We conclude that cancer has been recognized in India since antiquity. India’s current burden of a million incident cancers is the result of an epidemiologic transition, improved cancer diagnostics, and improved cancer data capture. The increase in cancer in India with wide interstate variations offers useful insights and important lessons for developing countries in managing their increasing cancer burdens.

Abstract
Oral squamous cell carcinoma (OSCC) represents one of the most common but scarcely known malignancies worldwide. The etiology of OSCC is strongly related to lifestyle habits and behavior, especially tobacco smoking and alcohol abuse. The mean age of individuals who start smoking and drinking alcohol is decreasing; thus, the aim of our campaign was to test the awareness and increase knowledge of oral cancer and its risk factors among young preadolescents. Six schools with 460 students aged 12-14 years were included in the campaign. A lecture about carcinogenesis and oral cancer was provided. Anonymous questionnaires were submitted to the students before and after the lecture, to test their knowledge, awareness, and understanding. Before the lecture, the students showed very little awareness of oral cancer (26.8%), although almost all of them identified tobacco smoking as a risk factor (92.2%). After the lecture, the students showed a significant understanding of the provided information, thus increasing their awareness. On scales of 1-10, the students rated the appropriateness of the campaign at 8.9 and their overall appreciation at 8.7. Social campaigns, especially among young students, seem to be appreciated and may represent a powerful strategy for increasing knowledge about cancer risk factors, especially when they are highly related to lifestyle habits and behavior.

Abstract
Background: Betel nut chewing is a public health concern in the Asia-Pacific region and is an emerging issue in Vanuatu. Despite the significant health risks associated with betel nut chewing, few interventions have been undertaken to reduce its harm. Objectives: To investigate betel nut use in Vanuatu and to identify opportunities to reduce its harm and possible interventions, framing the responses using the World Health Organization's MPOWER tobacco control model. Method: Qualitative research design, in the form of semi-structured interviews with ten participants with expertise in health, agriculture, education or non-communicable disease in Port Vila, Vanuatu during June 2017. Recorded interviews were transcribed verbatim, and a general inductive approach was used to identify key themes. Results: Participants reported a recent increase in betel nut use in Vanuatu due to the influence from Papua New Guinea and the Solomon Islands. To reduce the harm of betel nut use in Vanuatu, participants suggested policies and strategies that aligned with the MPOWER framework that could be adopted for betel nut control, including restricting cultivation and sale of betel nut in Vanuatu and using radio and existing community networks to reach people with messages about the dangers of betel nut use. Conclusion: Betel nut use may be growing in popularity in Vanuatu, where there are potential policy options to minimize harm. The MPOWER model for tobacco control may be a useful framework to help the Vanuatu government to deliver a comprehensive approach to reducing harm from betel nut use.

Abstract
Background: Betel nut use is a public health issue in the Asia-Pacific region that is often neglected. To control betel nut use, understanding of the adverse effects of betel nut use and evidence-based policies and strategies is necessary. Objectives: This narrative review aims to characterize the current situation on betel nut use at a global level regarding the epidemiology, pharmacology and toxicology, health effects, treatment options, policies and strategies. Methods: We found 139 existing literature published between 1970-2019 on the Web of Science database and other technical documents to collate the most relevant information on betel nut use. Data were categorized into appropriate themes. Results: The literature demonstrates that there is a lack of up to date statistics on betel nut use. There is limited research on the effect of policies and strategies to control betel nut use. Conclusion: Betel nut-chewing countries should focus on understanding which populations chew betel nut and implement appropriate policies, educational and cessation programs to help control betel nut use.

Abstract
Background According to GLOBOCAN 2018, oral cancer was reported as the second highest cancer prevalent in India. Despite the several therapies available for oral cancer treatment, tumor recurrence and distant metastasis persist. This study investigates the anticancer potential of Persicaria odorata, commonly known as Vietnamese coriander, used widely in traditional systems of medicine for the treatment of inflammation, stomach ailments, tumors, etc. Methods The crude methanolic extract of P. odorata (MPo) was prepared. The anticancer properties of MPo on SAS cells and other human oral squamous cell carcinoma cell line were evaluated using in vitro experimental conditions. The phytochemical constituents present in the MPo were also determined. Results Persicaria odorata possesses antiproliferative, antisurvival, antimetastatic activities, and induced cell cycle arrest in the G2 phase. It inhibited Akt-mammalian target of rapamycin (mTOR) signaling pathway and also downregulated the expression of essential proteins that are involved in tumorigenesis such as cyclin D1, cyclooxygenase 2 (COX2), survivin, matrix metalloproteinase-9 (MMP-9), and vascular endothelial growth factor-A (VEGF-A). Moreover, the presence of flavonoids and quinones also revealed the anticancer activity of the plant. Conclusion Overall, our study concludes that P. odorata exhibits its anticancer properties through the downregulation of Akt/mTOR signaling pathway in a dose-dependent manner.

Abstract
Background Oral cancer is one of the most common types of cancers in India. Radiotherapy is one of the treatment options frequently resulting in complications. These complications affect the patient's quality of life, nutritional intake, and consequently undermine the treatment outcomes. Patients' verbal accounts of experiences regarding their overall oral health during radiotherapy have not been described sufficiently. Aim The aim of the current study was to identify and analyze the issues experienced by patients while undergoing radiotherapy for oral cancer treatment. Materials and Methods A phenomenology study design was chosen, with in-depth interviews as the selected strategy for data collection. A literature search was conducted based on which an interview guide in English was prepared and modified according to inputs from subject matter experts. The interview guide comprised nine questions, including opening, key, and closing questions, and was also translated into Telugu and Kannada - the two languages predominantly spoken by the patients visiting the hospital. Interviews were conducted with each patient separately, with each interview lasting for 60 min each. The interviews were audio-recorded, transcribed, coded, and categorized, following which themes were derived from the analysis. Results The key theme that emerged from the study was the "Multifaceted experience of patients undergoing radiotherapy." Conclusion Understanding the specific issues faced by oral cancer patients undergoing radiotherapy drew our attention to the dire need for interprofessional collaboration, which could enable health professionals to share their expertise and perspectives toward achieving the common goal of restoring patients' health and improving health outcomes.

Abstract
Background Oral leukoplakia (OL) is a potentially malignant disorder with increased risk for the development of oral squamous cell carcinoma (OSCC). Many cases of OSCC arise from the malignant transformation of preexisting OL. However, the risk of progression into OSCC and the possible prediction of malignant potential of OL remain inconclusive. Recent studies have shown that podoplanin, a mucin-like transmembrane glycoprotein specifically expressed in lymphatic endothelial cells, is expressed in various neoplasms including OSCC, indicating its possible biologic role in tumor cells. In this study, an evaluation of podoplanin expression in OL and OSCC has been carried out to assess its potential role as a biomarker to predict the possibility of malignant transformation in OL cases. Aims and Objectives To assess the usefulness of podoplanin as a potential biomarker for predicting the risk of malignant transformation in OL, by comparing its immunohistochemical expression in OL and OSCC. Materials and Methods Archival paraffin-embedded blocks of 25 OL cases with varying grades of dysplasia and 30 OSCC cases showing its varying grades were selected. Sections were subjected to immunohistochemical staining for podoplanin and compared with the control group for evaluation of results in the three groups. Results A statistically significant increase in podoplanin expression was observed from normal mucosa through OL to OSCC. In the OL cases, the podoplanin staining score progressively increased from mild dysplasia to carcinoma in situ, whereas in OSCC, well-differentiated group showed the maximum expression of podoplanin. Conclusion The progressive increase in podoplanin expression through the increasing grades of dysplasia in OL is suggestive of an increased risk for malignant transformation with increased expression of podoplanin in OL cases. A high podoplanin expression in the well-differentiated OSCC may indicate a vital role for podoplanin in the early stages of tumorigenesis.

Abstract
Oral cancer is causally associated with environmental carcinogens, and the susceptibility to carcinogen-mediated tumorigenesis is proposed to be genotype-dependent. Leptin (LEP) and leptin receptor (LEPR) both play a crucial role in the mediation of physiological reactions and carcinogenesis and may serve as a candidate biomarker of oral cancer. The current case-control study aimed to examine the effects of LEP -2548 G/A (rs7799039), LEPR K109R (rs1137100), and LEPR Q223R (rs1137101) single-nucleotide polymorphisms (SNPs) with or without interacting to environmental carcinogens on the risk for oral squamous cell carcinoma. The SNPs of three genetic allele, from 567 patients with oral cancer and 560 healthy controls in Taiwan were analyzed. The results shown that the patients with polymorphic allele of LEP -2548 have a significant low risk for the development of clinical stage (A/G: adjusted odds ratio [AOR] = 0.670, 95% confidence interval [CI] = 0.454-0.988, P < 0.05; A/G + G/G: AOR = 0.676, 95% CI = 0.467-0.978, P < 0.05) compared to patients with ancestral homozygous A/A genotype. In addition, an interesting result was found that the impact of LEP -2548 G/A SNP on oral carcinogenesis in subjects without tobacco consumption is higher than subjects with tobacco consumption. These results suggest that the genetic polymorphism of LEP -2548 G/A (rs7799039), LEPR K109R (rs1137100), and LEPR Q223R (rs1137101) were not associated to the susceptibility of oral cancer; SNP in LEP -2548 G/A showed a poor clinicopathological development of oral cancer; population without tobacco consumption and with polymorphic LEP -2548 G/A gene may significantly increase the risk to have oral cancer.

Results of a randomized controlled trial of level IIb preserving neck dissection in clinically node-negative squamous carcinoma of the oral cavity. World J Surg Oncol 2018; 16:219. [PMID: 30409212 PMCID: PMC6225726 DOI: 10.1186/s12957-018-1518-z] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2018] [Accepted: 10/24/2018] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The lymphatic spread from the cancers of the oral cavity follows an orderly progression and involvement of lower nodes without involvement of upper nodes and skip metastasis is rare. Selective neck dissections are increasingly being performed for node-positive patients; however, in node-negative patients the options of wait and watch, prophylactic radiotherapy, and prophylactic elective node dissections are debated. Quality of life and shoulder functions are important to choose the appropriate therapeutic modality. PATIENTS AND METHODS Patients with oral squamous carcinoma with clinically and radiologically negative neck were randomized to IIb preserving superselective neck dissection or conventional supraomohyoid neck dissection. The primary end point of the study was recurrence of disease (clinical or radiological) and shoulder function as demonstrated by the clinical examination and electromyography. The secondary end point was quality of life as measured by the FACT-HN version 4 questionnaire at the end of 1 year follow-up. RESULTS The mean number of lymph node harvested per patient was 25.6 (range 8-85). Of the 32 patients, 3 had histologically positive node in level Ib, one of these patients had single positive node while the remaining two had three positive nodes in level Ib. At median follow-up of 36 months disease-free survival in IIb, sparing group was 83% compared to 91% in control arm, the difference in survival between two groups was statistically not significant (p = 0.694). EMG of the shoulder showed denervation pattern in 45% patients undergoing IIb preserving surgery at 1 month follow-up compared to 95% in conventional surgery group, this recovered in all patients but one at 3 months and 100% recovery was seen at 6 months. CONCLUSIONS The results of the present study indicate that superselective IIb preserving neck dissections are technically feasible and appear to be oncologically safe procedures when performed as elective prophylactic procedures in highly select group of patients. A significant number of occult metastasis seen in the present study suggests prophylactic dissection to be better than wait and watch policy. Results also show initial higher shoulder morbidity at 1 month in patients undergoing IIb preserving dissections; however, at the end of 1 year recovery is complete and both procedures are comparable. TRIAL REGISTRATION The trial is registered at clinicaltrials.gov with registration no NCT00847717 ; registered on February 19, 2009.

Evaluation of Mucociliary Activity in Maxillary Antra in Patients with Squamous Cell Carcinoma of Buccal Mucosa Undergoing Post Operative Radiotherapy. Indian J Otolaryngol Head Neck Surg 2018; 71:2082-2086.

Abstract
A prospective longitudinal observational study was conducted on 24 patients of histopathologically confirmed squamous cell carcinoma of buccal mucosa upon whom bilateral 'middle meatal antrostomy was performed during the same sitting as the tumour resection with the main aim to assess the maxillary mucociliary clearance, pre-, during and post-irradiation; and compare the findings with the non-irradiated side in the same patient to avoid any confounding factors. All patients underwent methylene blue dye clearance and saccharine clearance tests before the commencement of radiation therapy, weekly during irradiation and again at first and sixth month of completion of irradiation. Pre-radiation there was statistically no difference (P > 0.05) in clearance times between both sides. But, there was a significant (P < 0.001) increase in saccharin and methylene blue clearance times on the irradiated side in comparison to contralateral non-irradiated side, during and post-radiation. It is concluded that external beam radiotherapy for oral cancers significantly affect ciliary activity in the adjacent maxillary antrum and has no effect on the opposite side. Recovery in mucociliary activity was not seen even after 6 months after radiation therapy.

Abstract
Southeast Asia, especially India, is well known for the highest use of smokeless tobacco. These products are known to induce oral squamous cell carcinoma. However, not all long-term tobacco-chewers develop oral squamous cell carcinoma. In addition, germline variants play a crucial role in susceptibility, prognosis, development, and progression of the disease. These prompted us to study the genetic susceptibility to oral squamous cell carcinoma among the long-term tobacco-chewers. Here, we presented a retrospective study on prolonged tobacco-chewers of Northeast India to identify the potential protective or risk-associated germline variants in tobacco-related oral squamous cell carcinoma along with HPV infection. Targeted re-sequencing (n = 60) of 170 genetic regions from 75 genes was carried out in Ion-PGM™ and validation (n = 116) of the observed variants was done using Sequenom iPLEX MassARRAY™ platform followed by polymerase chain reaction-based HPV genotyping and p16-immunohistochemistry study. Subsequently, estimation of population structure, different statistical and in silico approaches were undertaken. We identified one nonsense-mediated mRNA decay transcript variant in the DFNA5 region (rs2237306), associated with Benzo(a)pyrene, as a protective factor (odds ratio = 0.33; p = 0.009) and four harmful (odds ratio > 2.5; p < 0.05) intronic variants, rs182361, rs290974, and rs169724 in SYK and rs1670661 in NELL1 region, involved in genetic susceptibility to tobacco- and HPV-mediated oral oncogenesis. Among the oral squamous cell carcinoma patients, 12.6% (11/87) were HPV positive, out of which 45.5% (5/11) were HPV16-infected, 27.3% (3/11) were HPV18-infected, and 27.3% (3/11) had an infection of both subtypes. Multifactor dimensionality reduction analysis showed that the interactions among HPV and NELL1 variant rs1670661 with age and gender augmented the risk of both non-tobacco- and tobacco-related oral squamous cell carcinoma, respectively. These suggest that HPV infection may be one of the important risk factors for oral squamous cell carcinoma in this population. Finally, we newly report a DFNA5 variant probably conferring protection via nonsense-mediated mRNA decay pathway against tobacco-related oral squamous cell carcinoma. Thus, the analytical approach used here can be useful in predicting the population-specific significant variants associated with oral squamous cell carcinoma in any heterogeneous population.

Abstract
Oral cancers are one of the most common cancers in India. These patients have pain during the course of the disease. Various drugs including opioid and nonsteroidal anti-inflammatory drug have been used to manage pain. However, these are associated with side effects such as constipation and vomiting. An early interventional block may decrease the requirement for analgesics and improve the overall quality of life. We describe a case of oral carcinoma successfully managed with ultrasound-guided pterygopalatine block.

Abstract
Abstract Introduction The incidence of lip, oral cavity and oropharynx cancer in Brazil is one of the highest worldwide. Objective This study aimed to identify predictors for oral cancer in Brazil between 2010 and 2013. Method Through a time series study in which 14,959 primary head and neck cancer diagnoses were evaluated. The variables of interest were gender, age, race, education level, family history of cancer, alcohol consumption, smoking, and previous cancer diagnosis. The outcome variable was divided into “oral cancer” and “cancer of other head and neck regions.” The data were analysed by multiple binary logistic regression; α=5%. Result The protective factor was: approximately 12 years of education (OR = 0.85). The risk factors were: being an ex-consumer (OR=1.19) or consumer (OR=1.11) of alcohol, tobacco use (OR=1.35) and a prior diagnosis of cancer that went untreated (OR=1.21). Conclusion Was concluded that the oral cancer had the following predictors compared to other types of head and neck cancer during the same period: approximately 12 years of education (protective factor) and ex-consumer or consumer of alcohol, smoking and previous diagnosis of cancer that went untreated (risk factors).

Abstract
OBJECTIVES To examine the political priority of oral health in India and to understand the underlying reasons for the political support oral health receives. METHODS The analysis is based on the political power framework developed by Shiffman and Smith and modified by Benzian et al. to examine the factors that contribute to the political priority of oral health in India. The framework comprises four main analysis categories, further subdivided into 11 dimensions. Based on the set of criteria, each dimension was analyzed and rated by assigning a score to assess to what extend the criteria were met. RESULTS There is a good understanding on what defines an oral health problem, however, there is no consolidated and comprehensive approach to address oral diseases. Despite India's efforts to improve oral health-related research, its poor utilization in terms of public health and population-based approaches is apparent. The absence of a national surveillance system for oral health masks the severity and extent of the oral disease burden and limits the basis for advocacy on improving oral health to health decision makers. The fragmentation of actors and institutions and the absence of leaders uniting various actors in oral public health impede changes toward improving the oral health status of the population. CONCLUSIONS Limited accessibility to oral health care, poor portrayals of the severity and extent of the burden, and inertia to address-related challenges are important factors contributing to the low political priority of oral health.

Abstract
Background: The ARID2 gene, encoding a sub unit of the chromatin remodelling complex, has a possible tumour
suppressor function and has been found to be frequently mutated in various tumours, including gingivo buccal oral
squamous cell carcinomas. The present study was designed to analyse the presence of ARID2 gene mutations in the
distinct genetic South Indian (Dravidian) population. Materials and Methods: Genomic DNA from thirty biopsy
tissue samples of histopathologically confirmed cases of oral squamous cell carcinoma (OSCC) were subjected to PCR
amplification with intronic primers encompassing exons 19 and 20 of ARID2. Subsequently, the PCR amplicons were
purified and subjected to Sanger sequencing using forward primers for analysis of mutational status. Results: Our
study yielded a 6% occurrence of mutations in the ARID2 gene among the thirty OSCC samples. Two samples showed
a C(5174)A nonsense mutation whereby the “C” nucleotide was substituted with an “A” nucleotide at position 5174,
resulting in the conversion of serine amino acid at codon 1725 to a premature STOP codon. Conclusion: Identification
of ARID2 gene mutations in OSCCs in this distinct ethnic population reaffirms that aberrations in the chromatin
remodelling complex could indeed also contribute to tumorigenesis, thus providing new insights for future research.
