Abstract
OBJECTIVE The aim was to research ACTL6A's role in oral squamous cell carcinoma (OSCC). METHODS OSCC and normal samples were obtained from patients and public databases. GSEA was performed. CIBERSORT was utilized to analyze immune landscape. Kaplan-Meier survival analysis and multivariate Cox regression analysis were conducted. After knocking down ACTL6A, we performed MTT assay, transwell assays, and flow cytometry to detect the impact of knockdown. RESULTS ACTL6A expressed higher in OSCC samples than normal samples. The CNV and mutation rate of TP53 was higher in ACTL6A high-expression group. TFs E2F7 and TP63 and miRNA hsa-mir-381 were significantly related to ACTL6A. ACTL6A could influence immune microenvironment of OSCC. Knockdown of ACTL6A inhibited OSCC cells' proliferation, migration, and invasion. ACTL6A was able to predict OSCC prognosis independently. CONCLUSION ACTL6A expressed higher in OSCC than normal samples and it could be used as an independent prognostic marker in OSCC patients.

[PMID: 39006719 PMCID: PMC11246185 DOI: 10.7759/cureus.62270] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2024] [Accepted: 06/12/2024] [Indexed: 07/16/2024] Open
Abstract
The scientific literature dealing with alcohol and alcoholic beverages revealed that these drinks possess an adverse impact on periodontal tissues. Additionally, other principal risk factors include tobacco, smoking, poor oral hygiene, etc. It has been observed that among chronic alcoholics, there are further issues, such as mental, social, and physical effects, that promote alcoholism. These people may have weak immunity for defense against pathogenic organisms and bacteria. Thus, chances of gingival bleeding, swollen gums, bad breath, and increased bone loss are there. Different alcoholic beverages in the market cause less salivation; these beverages contain sugars that promote acid production in the oral cavity by pathogens that demineralize the enamel and damage gum and teeth. This chronic alcohol consumption can progress into different types of oral disorders, including cancer, halitosis, and caries, and is also associated with tobacco and smoking. Chronic alcohol consumption can cause alteration of the oral microbiome and increase oral pathogens, which lead to periodontal disease and an environment of inflammation created in the body due to malnutrition, diminished immunity, altered liver condition, brain damage, and gut microbiota alteration. Heavily colored alcoholic beverages produce staining on teeth and, due to less saliva, may cause other toxic effects on the periodontium. Over-dependency on alcohol leads to necrotizing lesions such as necrotizing gingivitis, necrotizing periodontitis, and necrotizing stomatitis. These pathological impairments instigate severe damage to oral structures. Therefore, proper counseling by the attending dental surgeon and related health professionals is urgently required for the patient on the basis that the individual case needs to go away from the regular heavy consumption of alcohol.

Abstract
Background and Aims Oral squamous cell carcinoma is the most prevalent malignancy in the oral cavity, with a significant mortality rate. In oral squamous cell carcinoma patients, the survival rate could decrease because of delayed diagnosis. Thus, prevention, early diagnosis, and appropriate treatment can effectively increase the survival rate in patients. In this systematic review, we discussed the role of different genes in oral squamous cell carcinoma metastasis. Herein, we aimed to summarize clinical results, regarding the potential genes that promote oral squamous cell carcinoma metastasis. Methods This systematic review was carried out under the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. An electronic search for all relevant articles published in English between January 2018 and April 2022 was performed using Scopus, PubMed, and Google Scholar search engines. All original studies published in English were included, and we excluded studies that were in a non-English language. Results A total of 4682 articles were found, of which 14 were relevant and detected significant genes in oral squamous cell carcinoma progression. These findings investigated the overexpression of interferon-induced proteins with tetratricopeptide repeats 1 and 3 (IFIT1, IFT3), high-mobility group A2 (HMGA2), transformed growth factor-beta-induced, lectin galactoside-binding soluble 3 binding protein (LGALS3BP), bromodomain containing 4, COP9 signaling complex 6, heterogeneous nuclear ribonucleoproteins A2B1 (HNRNPA2B1), 5'-3' exoribonuclease 2 (XRN2), cystatin-A (CSTA), fibroblast growth factors 8 (FGF8), forkhead box P3, cadherin-3, also known as P-cadherin and Wnt family member 5A, ubiquitin-specific-processing protease 7, and retinoic acid receptor responder protein 2 genes lead to promote metastasis in oral squamous cell carcinoma. Overexpression of some genes (IFIT1, 3, LGALS3BP, HMGA2, HNRNPA2B1, XRN2, CSTA, and FGF8) was proven to be correlated with poor survival rates in oral squamous cell carcinoma patients. Conclusion Studies suggest that metastatic genes indicate a poor prognosis for oral squamous cell carcinoma patients. Detecting these metastatic genes in oral squamous cell carcinoma patients may be of predictive value and can also facilitate assessing oral squamous cell carcinoma development and its response to treatment.

Abstract
There are numerous therapeutic applications for ginsenoside Rb1 (GRb1), the primary saponin derived from ginseng root. According to earlier research, ginsenoside Rb1 causes apoptosis and reduces the cell cycle. Its adverse effects, especially those on the development of the embryo, still need to be thoroughly studied. A host's lifestyle choices, including smoking, drinking too much alcohol, using tobacco products, and having an HPV infection, can increase the risk of oral squamous cell carcinoma (OSCC), one of the most prevalent malignancies of the oral cavity. To address this challenge, this investigation focuses on the design of GRb1 for treating OSCC. In vitro cytotoxicity studies confirmed that GRb1 was more effective in PCI-9A and PCI-13 cells, with reduced toxicity in non-cancerous cells. Further verification of cellular morphology was achieved through various biochemical staining methods. The mechanism of cell death was investigated by Annexin V-FITC and PI methods. Additionally, the antimetastatic attributes of GRb1 have been evaluated using both migration scratch and Transwell migration assays, which have collectively revealed excellent antimetastatic potential. The DNA fragmentation of the PCI-9A and PCI-13 cells was assessed using a comet assay. Ginsenoside Rb1 improved ROS levels and caused mitochondrial membrane potential alterations and DNA damage, which resulted in apoptosis. OSCC administration significantly reduced the levels of SOD, GSH, GPx, and CAT, increasing the levels of PCI-9A and PCI-13 cells, while GRb1 improved this situation. Therefore, we propose that Ginsenoside Rb1 could be an alternative therapeutic strategy for OSCC therapy.

Abstract
Background Tobacco is one of the main etiological factors for oral squamous cell carcinoma (OSCC) and oral potentially malignant disorders (OPMD). CYP1B1 is an enzyme which plays a major role in the phase I detoxification of tobacco, the byproducts of which are subsequently detoxified by phase II enzymes Glutathione S Transferase (GST). We attempted to evaluate the L432V polymorphism and tissue expression of CYP1B1, along with the oxidant-antioxidant status in OSCC progression model. Method ology: Tissue biopsies and blood samples were collected from the subjects; L432V polymorphism was evaluated by TaqMan RT-PCR, immunohistochemistry was performed on the tissue sample using CYP1B1 polyclonal primary antibody and Allred quick scoring system was used to evaluate the stained slides. Malonaldehyde (MDA) and GST activity were measured spectrophotometrically to assess oxidative-antioxidative status. Results When the L432V polymorphism was analyzed, it was observed that in oral epithelial dysplasia (OED) and OSCC, CG was more common than GG genotype. Highest mean Allred score was observed in tobacco users (6.27), highest GST activity was seen in oral epithelial dysplasia (5.006 U/ml) and highest MDA activity was observed in OSCC (1553.94 nm/ml). Conclusion Tobacco users with CG and GG genotypes are at equal risk of developing oral epithelial dysplasia or OSCC and L432V polymorphism does not appear to increase the risk of malignant transformation in oral epithelial dysplasia. Moreover, tobacco users with GG genotype and tissue expression of CYP1B1 may be at a greater risk of oxidative damage.

Abstract
Background There is a lack of health care facilities and poor oral health awareness among the rural adult population of Jharkhand which may significantly influence oral health status and lifestyle scores. Aim To assess the oral hygiene status, lifestyle factors, and various risk factors associated with poor lifestyle scores in the rural adult population of Jharkhand. Materials and Methods This cross-sectional study included 400 rural adults (35-44 years) populations. Face-to-face interviews were used to collect sociodemographic data and data on oral hygiene practices. Lifestyle factors were assessed using Health Practice Index (HPI). Oral health status was assessed using the oral health assessment proforma provided by the World Health Organization (WHO). Results A significantly higher (p value < 0.0001) prevalence of tobacco consumption was reported by males (94.0%) compared to females (4.0%). The males (54.0%) reported significantly higher (p value < 0.0001) poor lifestyle scores compared to females (38.0%). A significantly higher (p value < 0.0001) number of oromucosal lesions (13.0%) was found in males compared to females (1.0%). There was a significant difference (p value < 0.0001) in the oral hygiene status between males and females with majority of males (60.0%) having poor oral hygiene. A bivariate analysis was performed, and unadjusted odds ratio was computed. The factors that became significant were then entered into logistic regression model (enter method). The results of logistic regression analysis showed that education (OR = 0.3, p value = 0.003), systemic diseases/long-term medication (OR = 2.9, p value = 0.004), tobacco consumption (OR = 2.9, p value = 0.006), oral hygiene status (OR = 2.4, p value = 0.007), and dental caries (OR = 2.9, p value = 0.004) were significant predictors of poor lifestyle scores. Conclusion The rural adult population in Jharkhand has poor oral hygiene status and poor lifestyle scores. It is important to raise awareness regarding good oral hygiene and the negative effects of tobacco consumption. The dental visit should be encouraged, and the concept of preventive care needs to be instilled.

Abstract
Background Oral squamous cell carcinoma (OSCC) and oral leukoplakia (OL) with dysplasia are closely linked conditions in the oral cavity, with the latter often indicating precancerous changes, underscoring the urgency of early detection and intervention. Histopathological confirmation is crucial for accurate diagnosis. The nucleolar organizer region (NOR), specifically analyzed through silver-staining (argyrophilic NORs), provides insights into nuclear changes associated with the lesion. Computer-assisted morphometric analysis enhances precision and objectivity in evaluating AgNOR-related parameters. Aim To conduct a computer-assisted morphometric comparison of AgNORs using various NOR-related parameters in cases of OSCC and leukoplakia with dysplasia and to evaluate their diagnostic significance. Materials and methods A computer-assisted morphometric analysis was conducted using various NOR-related parameters, such as nuclear profile area, single AgNOR profile area per nucleus, total AgNOR profile area per nucleus, and number of AgNOR profiles per nucleus on a total sample of 90 specimens, which includes leukoplakia with dysplasia (30), OSCC (30), and a control group, including 30 samples of normal oral mucosa. A comparison was conducted on the morphometric values between the groups under investigation. Tukey's multiple comparison tests and ANOVA were used to analyze the data and determine the differences between the groups. Results The present investigation revealed a significant difference in all four AgNOR-related parameters between leukoplakia and OSCC in comparison to the control group (normal oral mucosa). Comparing OL (41.78 ± 0.46) and OSCC (62.78 ± 0.47) to the control group (35.93 ± 0.99), the mean value of nuclear profile area (A Nuc) was significantly greater. In comparison to the control group (3.40 ± 0.09), the mean value of a single AgNOR profile area per nucleus (A NOR) was found to be relatively lower in both research groups, OL (2.00 ± 0.02) and OSCC (1.39 ± 0.01). The total AgNOR profile area per nucleus (TA NOR) had a mean value of 10.61 ± 0.69 in OL and 12.05 ± 0.28 in OSCC, respectively, compared to 7.82 ± 0.38 in the control group. The study found that there was more number of profiles of AgNORs per nucleus (n NOR) in the study groups of OL (5.30 ± 0.29) and OSCC (8.69 ± 0.19) than in the control group (2.32 ± 0.11). Conclusion The parameters linked to the NOR are biologically informative and easy to check regularly in a pathology lab. Additionally, AgNORs give us important information that enables us to study the range of nuclear changes in malignant and potentially malignant lesions.

Abstract
BACKGROUND Given the paucity of current safety studies related to e-cigarettes, there are no definitive studies on whether e-cigarettes cause oral mucosal lesions or even oral cancer. Although it is still undetermined whether e-cigarettes are harmless, an increasing number of teenagers choose to smoke e-cigarettes and believe that they are not harmful to the human body. OBJECTIVE This aims to determine whether e-cigarettes cause damage to the oral mucosa. This study also aims to evaluate the association between e-cigarette smoking and oral mucous membrane lesions in young adults. The objectives are to (1) compare the oral mucosal conditions in participants with and without e-cigarette smoking habits, (2) assess the effect of the amount of e-cigarette smoking on oral mucosal conditions, and (3) assess the effect of the duration of e-cigarette smoking on oral mucosal conditions. METHODS In this prospective study, 304 youths aged 15 to 24 years (n=152, 50% who smoke only e-cigarettes and n=152, 50% who do not smoke e-cigarettes or cigarettes) will be divided into 2 groups for a controlled study. Whether e-cigarettes cause oral mucosal lesions will be verified by comparing the odds of oral mucosal lesions in the 2 experimental groups. For this experiment, the predefined power is 80% (P=.04), and the predefined proportions of groups 1 and 2 are 11% and 2.5%, respectively. RESULTS This experiment is at the conceptualization phase and has not yet been carried out. Experimenters have not been recruited and no data have been collected. CONCLUSIONS e-Cigarettes are still an unfamiliar topic to the public, and it is still unknown whether they can cause damage to the oral mucosa. This experiment aims to find out whether there is a link between the 2. There are still many limitations in this study, such as the lack of categorization of e-cigarettes and the lack of testing methods for oral mucosal status. These limitations are expected to be addressed in the future as the experiment is formally conducted and further optimized. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID) PRR1-10.2196/53644.

Abstract
Aim Urine as a biofluid has been rarely used as a diagnostic fluid in oral diseases. The article aims to systematically review the utility of human urinary carcinogen metabolites as an approach for obtaining important information about tobacco and cancer. Materials and Methods The following article reviews the use of urine and its metabolites as biomarkers in various lesions of the oral cavity including oral squamous cell carcinoma and as a screening method in evaluating tobacco and its components. A bibliographic comprehensive search was carried out in the main databases: PUBMED, SciELO, Google Scholar, VHL, and LILACS for articles that were published from 1985 to 2020. The inclusion criteria were "urinary metabolites," "oral cancer/HNSCC," "body fluids," "tobacco," and "metabolomics." A total of 55 articles were collected which included laboratory studies, systematic reviews, and literature of urinary metabolites in tobacco users. Results Most of the studies carried out show accurate results with high sensitivity of urinary metabolite biomarkers in individuals with tobacco-based habits and lesions caused by them. Conclusion The review indicates that urinary metabolite analysis demonstrates its applicability for the diagnosis and prognosis of disease. Urine is a remarkable and useful biofluid for routine testing and provides an excellent resource for the discovery of novel biomarkers, with an advantage over tissue biopsy samples due to the ease and less invasive nature of collection.

Strategies adopted by oral physicians, oral and maxillofacial surgeons, and oral pathologists in patient education on oral cancer: A Nigerian study. Cancer Rep (Hoboken) 2024; 7:e1929. [PMID: 37884691 PMCID: PMC10809197 DOI: 10.1002/cnr2.1929] [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: 06/28/2023] [Revised: 09/25/2023] [Accepted: 10/16/2023] [Indexed: 10/28/2023] Open
Abstract
BACKGROUND The burden of oral cancer in Nigeria is increasing. Different studies have shown how public education on oral cancer have increased knowledge of oral cancer across populations, however, it is not known if these practices are adopted by oral physicians, oral and maxillofacial surgeons, and oral pathologists in Nigeria. AIMS To investigate the patient oral cancer education strategies adopted by oral physicians, oral and maxillofacial surgeons, and oral pathologists in Nigeria. METHODS This study adopted an analytical cross-sectional study design. This study surveyed practicing oral physicians, oral and maxillofacial surgeons, and oral pathologists in Nigeria. An e-questionnaire was used for this study. The data were analyzed using the SPSS Version 20 software, and a p-value of <.05 was used to determine the level of statistical significance. RESULTS The study's response rate was 46.6% (75/161). The 75 participants were from the six geopolitical zones in Nigeria responded to the survey questionnaire. Even though more than half (43/75, 57.3%) of the respondents have never received any training since their post-bachelor's degree qualification on the strategies that can be used in educating patients on oral cancer, majority (54/75, 72.0%) of them knew at least one education strategy; also, the most known (36/54, 66.7%) and utilized (33/54, 61.3%) strategy among those respondents who were aware of patient education strategy was health talk. Only 38.7% (29/75) of the respondents reported that health learning materials (posters, leaflets, fliers, and flipcharts) are available in their clinics, all of which were in insufficient quantities. Also, 93.3% (70/75) of the respondents opined that it is worthwhile that dental clinics/hospitals in Nigeria invest in the provision of oral cancer learning materials for patient use. Inferential statistical analysis did not reveal any significant relationship between the respondents' characteristics and their awareness and practice on patient oral cancer education strategies. CONCLUSION This study identified that many oral physicians, oral and maxillofacial surgeons, and oral pathologists in Nigeria lack the needed capacity to educate their patients on oral cancer. There is a need to strengthen their capacity by giving them training on patient oral cancer education strategies, and by providing them with good quality and enough teaching aids.

Abstract
BACKGROUND Oral squamous cell carcinoma (OSCC) is the most common malignant neoplasms of the oral cavity. Tongue, buccal mucosa, and gingivobuccal sulcus are the most commonly involved sites for the local recurrence of OSCC. The site of the tumor can be a critical parameter in relation to the recurrence of OSCC because of the varied action of tumor cells in different tumor macro and microenvironments. Hence, the current study aims to evaluate the correlation between the site and recurrence of OSCC among patients visiting private oral cancer hospitals. MATERIALS AND METHODS Details of n=300 OSCC cases reported during 2019-2023, which included primary and recurrent OSCC, were collected. The sample population selected includes 261 primary and 39 recurrent oral squamous cell carcinoma cases. The demographic and clinicopathological data were retracted from the institution's common clinical database and transported to IBM-SPSS 23 software for statistical analysis. Chi-square was done to evaluate the association between site and recurrence status, and p<0.05 was considered statistically significant. RESULTS Males have a high predilection for OSCC, and the recurrent cases account for 13% of the sample population. The buccal mucosa was the most commonly affected site in primary and recurrent OSCC cases. However, the association between the site of the lesion and the status of recurrence was found to be statistically significant, with a p-value of 0.001. CONCLUSION Even though buccal mucosa was the most common site for recurrent OSCC(p value-0.001), the present study carries a small sample size and a location-specific sampling. Hence, further studies must be conducted with a large sample size to test the significant correlation between the site and recurrence rate among patients diagnosed with OSCC.

Abstract
Despite advances in surgical and oncological treatments, the incidence and five-year survival rates (~50 percent) of oral cancers (OC) have not improved over the last decades and remain a major public health problem. Seventy percent are still diagnosed at a late stage (T3 or T4), with an average delay in diagnosis of two to five months. As the cure and survival of patients are directly related to the development stage of the tumor at the time of diagnosis, the objective of this work was to analyze all the determinants related to oral cancer and to propose new clinical approaches for diagnosis and screening. A proposal for new models of screening, training, and concrete action to improve public awareness of the major global problem of OC is made. The strengths and weaknesses of OC screening studies need to be objectively understood to effectively guide and energize testing in primary care settings, with the prospect of using new and emerging technologies that can help improve the discriminatory accuracy of case detection. Most national organizations have not, to date, recommended population-based mass screening, due to a lack of sufficient scientific evidence of associated mortality reduction. Where health care resources are high, opportunistic individual screening is recommended, although the low diagnostic capacity of front-line clinicians is alarming.

Abstract
Background Sex-related discrepancies in the prognosis of oral cancer patients have not been clarified. This study aimed to assess survival outcomes and potential prognostic factors in female and male patients with oral cancer. Methods A retrospective search of the TriNetX network (TriNetX, Cambridge, Massachusetts, USA) was conducted to identify patients diagnosed with oral cancer (International Classification of Diseases (ICD)-10 codes C02-C06), within the past 20 years from the access date April 21, 2023. Patients were categorized according to sex (female vs. male). Following matching for age and risk factors such as nicotine dependence and alcohol abuse, Kaplan-Meier analysis was performed and risk, odds, and hazard ratios were calculated. Outcome variables were five-year disease-free survival (DFS) and overall survival (OS). Additionally, the female and male patient cohort were compared with regard to the novel diagnosis of depression (depressive episode, major depressive disorder, dysthymic disorder) after the tumor diagnosis. Results A total of 77,348 patients were assessed. After propensity score matching, 26,578 male and 26,578 female patients were included in each group (mean age 63 years). DFS (71.92% in females vs. 68.29% in males; hazard ratio (HR) 0.870; p < 0.001) and OS (77.08% in females vs. 71.74% in males; HR 0.793; p < 0.001) were significantly higher in the female cohort. However, in patients diagnosed with depression after the initial cancer diagnosis (N = 4,824), survival was worse in female patients compared to male patients (82.48% in females vs. 86.10% in males; HR 1.341; p < 0.001). Conclusion This retrospective case-control study showed that females with oral cancer had a better DFS and OS than males. However, survival in females with a newly diagnosed depression after the oral cancer diagnosis was worse compared to those of male oral cancer patients. Depression may be a relevant prognostic factor that contributes to sex disparities in oral cancer patients.

Abstract
Smokeless tobacco (SLT) is consumed by more than 300 million people worldwide. Studies show high use among Indian indigenous women who are also at high risk for oral cancers. Both human papillomavirus infection (HPV) and SLT have been associated with oral cancer, this study examined the presence of high-risk HPV in oral samples collected from tribal smokeless tobacco users in Mysuru, India. Between June and August 2019, 100 tribal females (50 SLT-users and 50 non-users) from rural Mysuru District, Karnataka, were enrolled in a cross-sectional study. Following informed consent, demographic data and oral samples were collected and processed using a digene HC2 High-Risk HPV DNA test (Qiagen, USA). On average participants were 45.5 (SD: ±6.6) years. Chronic SLT users were mostly married (73%), Hindu (100%), illiterate (62%), and employed (90%). One woman was positive for high-risk HPV infection. Oral HPV infection was low in this sample and this is consistent with the literature from other low and middle-income countries. SLT use is high in this group so interventions to reduce tobacco use are warranted.

Abstract
Introduction and Aims Today, smoking is recognized as the biggest cause of preventable premature death. dentists can play a very important role in motivating and providing smoking cessation counseling and play this role of line requires gaining sufficient knowledge and education during the student period. Therefore, the purpose of this study is to determine the knowledge and attitude of dental students in Kerman in the field of smoking cessation counseling. Methods and materials This study was descriptive-analytical and crosssectional. The study population was fourth, fifth and sixth year dental students. A questionnaire was used to assess participants knowledge and attitude towards smoking cessation, using the 5 As of smoking cessation. Data were collected using a questionnaire and analyzed using SPSS 21, t-test and chi-square software. Results This study showed that the mean score of students' knowledge was 2.13 ± 14.12. There was a significant relationship between knowledge score, gender (women more than men) and the presence of a smoker in the family (P = 0.01, 0.001, respectively). Also, the mean attitude score was 36.25 41 5.41. There was a significant relationship between attitude score, gender (women more than men) and the presence of a smoker in the family (P = 0.01, respectively). Conclusion Results of this study showed that the students have good knowledge of the 5As (Ask, Advice, Assess, Assist, Arrange) but that they did not have much information about some parameters under Assess. Also, they have a positive attitude in this regard. Moreover, students believed that time limitations in dental visits and concerns on the effectiveness of smoking cessation consultations are the major obstacle in implementing a smoking cessation plan.

Abstract
Background Recently, the role of biochemical factors in the etiology of oral squamous cell carcinoma (OSCC) has attracted some attention. Serum levels of biochemical factors may change in cancer patients. This study aimed to assess the serum level of folate, Vitamin B12, homocysteine, iron, copper, and selenium in patients with OSCC. Materials and Methods This descriptive analytical study was conducted on 30 primary OSCC patients (15 males and 15 females) presenting to Imam Khomeini Cancer Institute, who had not yet undergone treatment. Blood samples were taken and serum levels of folate, Vitamin B12, homocysteine, iron, copper, and selenium were measured. Serum levels of micronutrients in patients with different tumor sizes were analyzed by one-way ANOVA. Serum levels of micronutrients were compared among groups with and without metastasis and lymph node involvement using Student's t-test (P < 0.05). Results Serum levels of B12, folic acid, homocysteine, copper, iron, and selenium were 232.5 ± 102.68, 8.66 ± 4.06, 18.87 ± 8.81, 96.0 ± 22.64, 55.27 ± 40.58, and 92.47 ± 18.83 ng/mL, respectively. Relatively similar values were measured in patients with different tumor sizes with and without lymph node involvement and presence or absence distant metastasis. However, the serum level of folic acid in OSCC patients without lymph node involvement was significantly higher than that in OSCC patients with lymph node involvement (P < 0.05). Conclusion Despite some variations, serum levels of micronutrients in OSCC patients were within the normal limits. Considering the variations in serum level of copper in OSCC patients, it may be used as a diagnostic marker. However, further studies are warranted in this respect.

Abstract
Background Oral squamous cell carcinoma (OSCC) is the most common oral malignancy, representing up to 80-90% of all malignant neoplasms of the oral cavity. It results from the multistep accumulation of heterogeneous genetic changes. Important risk factors for OSCC include the use of tobacco or betel quid chewing, alcohol consumption, human papillomavirus and poor nutrition. E-Cadherin as a tumour suppressor gene sets a threshold for Wnt/β-catenin signalling. When expression of E-Cadherin is lost, potentiation of Wnt signalling pathway occurs leading to loss of cell-cell adhesion. The cyclin D1 gene (CCND1) located on chromosome 11q13 encodes a nuclear protein that is the regulatory subunit of Cdk-4 and Cdk-6. Cyclin D1 plays a major role in cell cycle transition from G1 to S phase by contributing to inactivation of the retinoblastoma gene product, and overexpression of CCND1 has been reported in 35-40% cases of OSCC. Aim Considering this, we decided to evaluate and compare the expression of CE-Cadherin and Cyclin D1 in different grades of OSCC. Materials and Methods A retrospective study was carried out on 60 formalin-fixed paraffin embedded tissue blocks comprising of 20 cases of well-differentiated OSCC, 20 cases of moderately differentiated OSCC and 20 cases of poorly differentiated OSCC. Diagnosed (using H and E), with oral mucosa taken as control. Results There was downregulation of E-Cadherin and overexpression of Cyclin D1 in increasing grades of OSCC and the difference was statistically significant. E-Cadherin was localised to membranous and shifted to cytoplasm as the grade worsened. Cyclin D1 was localised to nuclei of cells and the expression was seen more at the peripheral portions of tumour islands depicting the proliferative activity of tumour front. Conclusion The study revealed a good prognostic role of both E-Cadherin and Cyclin D1 in OSCC. The markers can be used for prognostic as well as therapeutic purposes.

Abstract
In this case report, a 32-year-old female patient from Central India was reported. Her primary complaint was pain and swelling in the lower left back region of her jaw, which had been present for one month. On extraoral examination, asymmetrical facial symmetry was observed, and a 3 cm swelling was present on the left side of her face. An intraoral examination showed a reddish-pink ulceroproliferative growth on the left buccal mucosa. Under local anesthesia, an incisional biopsy was performed. A conclusive diagnosis of well-differentiated squamous cell carcinoma affecting the left buccal mucosa was made based on clinical and histopathological testing. The patient was scheduled for a follow-up appointment after being referred to the Cancer Institute for the required treatment. After three months, the patient reported to the department with extensive swelling on the left side of the face, measuring 6 cm in diameter. On intraoral examination, a more restricted mouth opening compared to the previous examination. The ulceroproliferative growth was firm and tender and exhibited continuous bleeding. As the patient delayed seeking proper care, the condition became more aggressive, and she lost her life. This case of oral squamous cell carcinoma (OSCC) in a 32-year-old female patient is rare, as men are more commonly affected by OSCC in Central India due to their higher prevalence of unhealthy practices. This case highlights the rapid progression of the disease if appropriate treatment is not initiated promptly upon diagnosis.

Singh P, Kaul P, Singhal T, Kumar A, Garg PK, Narayan ML. Role of Sentinel Lymph Node Drainage Mapping for Localization of Contralateral Lymph Node Metastasis in Locally Advanced Oral Squamous Cell Carcinoma - A Prospective Pilot Study. Indian J Nucl Med 2023; 38:125-133. [PMID: 37456189 PMCID: PMC10348499 DOI: 10.4103/ijnm.ijnm_120_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2022] [Revised: 09/13/2022] [Accepted: 09/15/2022] [Indexed: 07/18/2023] Open
Abstract
Aim/Background Sentinel lymph node biopsy (SLNB) has become the standard of care for nodal staging in early-stage oral squamous cell carcinoma (OSCC) as an alternative to elective neck dissection. However, the role of sentinel lymph node (SLN) and lymphatic drainage mapping with image-guided surgery has not been studied in locally advanced OSCC. Therefore, this study was undertaken to evaluate the role of lymphatic drainage mapping in the identification of contralateral cervical lymph node metastasis in locally advanced OSCC (Stage III-IVb). Materials and Methods We have prospectively analyzed treatment-naïve patients of locally advanced, lateralized OSCC (n = 20). All patients underwent SLN imaging using peritumoral injection 0.5-1.0 mCi of 99 mTc-Sulfur colloid (Filtered) and intraoperative identification of contralateral neck nodes using a handheld gamma probe (Crystal Photonics). Results A total of 20 patients (18 males and 2 females) with a median age of 52.5 (33-70 years) were included. Ipsilateral SLN was localized in 18 (90%) patients. Bilateral cervical nodes were visualized only in 7 (35%) patients on lymphoscintigraphy (LSG). Out of the seven patients, 5 patients underwent bilateral neck dissection and 2 patients had unilateral neck dissection with LSG-guided exploration of contralateral cervical node and intraoperative frozen section examination. Six out of these seven patients had one or other risk factor for contralateral metastasis (patients had either primary in the tongue, involvement of floor of mouth, or tumor thickness >3.75 mm). On postoperative HPE, only 1/20 (5%) patient showed metastasis in the contralateral cervical lymph node. Conclusion Correct identification of metastatic disease in contralateral neck directly influences clinical management, as it can reduce contralateral neck failure rate and limit the morbidity associated with unnecessary contralateral neck dissection, and it is also crucial in radiotherapy planning in locally advanced OSCC. In the current study, lymphatic drainage mapping showed a metastatic rate of 5% in the contralateral neck nodes in locally advanced, lateralized OSCC. However, the role of SLNB and lymphatic drainage mapping in this subgroup of OSCC needs to be studied in larger population to validate these findings.

Abstract
Oral squamous cell carcinoma (OSCC) is the most common oral cancer, having high recurrence and metastasis features. In addition to surgery, photodynamic therapy (PDT) is considered as another effective approach for OSCC treatment. The water solubility of currently available PDT photosensitizers (PSs) is poor, lowering their singlet oxygen (1O2) yield and consequent PDT efficiency. Strategies of PS assembly have been reported to increase 1O2 yield, but it is still possible to further enhance PDT efficiency. In this work, we utilized apoptosis to amplify the assembly of porphyrin nanofibers for enhanced PDT of OSCC. A water-soluble porphyrin derivative, Ac-Asp-Glu-Val-Asp-Asp-TPP (Ac-DEVDD-TPP), was designed for this purpose. Upon caspase-3 (Casp3, an activated enzyme during apoptosis) cleavage and laser irradiation, Ac-DEVDD-TPP was converted to D-TPP, which spontaneously self-assembled into porphyrin nanofibers, accompanied by 1.4-fold and 2.1-fold 1O2 generations in vitro and in cells, respectively. The as-formed porphyrin nanofiber induced efficient cell apoptosis and pyroptosis. In vivo experiments demonstrated that, compared with the scrambled control compound Ac-DEDVD-TPP, Ac-DEVDD-TPP led to 6.2-fold and 1.3-fold expressions of Casp3 in subcutaneous and orthotopic oral tumor models, respectively, and significantly suppressed the tumors. We envision that our strategy of apoptosis-amplified porphyrin assembly might be applied for OSCC treatment in the clinic in the near future.

J Robot Surg 2023:10.1007/s11701-023-01572-4. [PMID: 36964850 DOI: 10.1007/s11701-023-01572-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2023] [Accepted: 03/11/2023] [Indexed: 03/26/2023]
Abstract
Transoral robotic surgery (TORS) approach for the treatment of oropharyngeal cancer allows for reduced patient morbidity, amongst other advantages over the traditional lip-splitting mandibulotomy method. Free-flap reconstruction is commonly utilized in head and neck cancer surgeries; however, safety and outcomes of this technique in TORS procedures have not been well studied. The objective of this study was to perform a systematic review to evaluate the efficacy and safety of TORS with free-flap reconstruction (TORS-FFR) for oropharyngeal cancer. A systematic search of Scopus, EMBASE, CINAHL and PubMed databases was completed. Following PRISMA guidelines, case series/reports, retrospective and prospective cohort studies were included. Primary outcomes measured were deaths and complication rates associated with TORS-FFR for oropharyngeal cancers. Secondary outcomes included functional swallowing and airway outcomes, operative time and length of hospital stay. Twenty-one studies met the inclusion criteria comprising a total of 132 patients. The mean patient age was 58.4 years. The most frequent complication was infection (8.9%) followed by flap wound dehiscence (4.2%). The average total operative time was 710 min (n = 48), while average length of hospital stay was 13.5 days (n = 48). Reconstructions were most commonly fashioned from radial forearm free flaps (RFFF), with anterolateral thigh flaps (ALT) representing the second most common free-flap subtype. TORS-FFR procedures for oropharyngeal cancer are safe, with low serious complication rates. This surgical approach may be associated with decreased length of hospital stay; however, further studies are required to better characterize post-operative outcomes.Level of evidence 1a.

Abstract
Tobacco use has detrimental effects on health, including oral health. The emergence and increasing popularity of newer tobacco and nicotine products make tobacco use one of the major public health problems in the world. Tobacco use increases the risk of oral diseases such as oral cancer, oral mucosal lesions, periodontal disease, and dental caries, among many other oral diseases and conditions. The dental office is an excellent venue for providing cessation intervention. However, there is a lack of knowledge and training in tobacco use prevention among dental professionals. More efforts are needed for smoking cessation interventions in the dental office. Smoking cessation interventions provided by oral healthcare providers include brief educational, behavioral, and pharmacological interventions. This review provides an overview of the ill effects of tobacco use on oral health and the role of oral healthcare providers in managing and preventing tobacco dependence.

Abstract
Background IFN-gamma and natural killer (NK) cells have been considered the most effective cells in the combat of cancer, contributing to better prognosis and longer survival. The aim of the study was to analyze and correlate the CD 57 immunopositive NK cell-mediated Interferon-γ pathway in regulating immune mechanisms in Oral Squamous Cell Carcinoma. Materials and Methodology The study sample was composed of a total of 40 cases of histopathologically confirmed cases of Oral Squamous cell carcinoma (OSCC). Clinical data such as age, gender, habit history, signs and symptoms, and TNM staging were obtained for each case. The biopsy specimens of the cases obtained were fixed with 10% neutral buffered formalin and processed and embedded in paraffin wax. 3-4 μ thick sections were taken for hematoxylin and eosin staining and immunohistochemistry procedure. A saliva sample was collected from each patient and stored at 20 degree Celsius for estimation of salivary interferon-gamma levels using the sandwich ELISA technique. Results CD 57 NK cells quantitative assessment was significantly associated with tumor budding, cell nest size, the pattern of invasion, lymphocytic host response, NK cell morphology, Depth of invasion, and Tumor thickness. The ratio of CD 57 immunopositive NK cells to salivary IFN-γ levels showed a significant association with histopathological grades, tumor size, and lymph node status. Conclusion Adoptive cellular transfer therapy with NK cells has been advocated in both experimental models and clinical trials in treating hematopoietic malignancies. The strategy is based on reviving the patient innate immune surveillance and control of tumor invasion by the infusion of activated NK cells. The IFN-gamma and NK cell infiltration in oral squamous cell carcinoma might show a distinctive tumor microenvironment with a favorable local cytotoxic immune response against neoplastic cells.

Abstract
SLC16A1-AS1 is a newly identified lncRNA with different roles in different cancers. MiR-5088-5p is an oncogenic miRNA in breast cancer. However, their participation in oral squamous cell carcinoma (OSCC) is unknown. We predicted the interaction between SLC16A1-AS1 and miR-5088-5p, and this study was carried out to explore the crosstalk between them in OSCC. A total of 56 OSCC patients donated OSCC and paired non-tumor tissues, which were used to detect the differential expression of SLC16A1-AS1 and miR-5088-5p (mature and premature). Analysis of the subcellular location of SLC16A1-AS1 in OSCC cells and its direct interaction with premature miR-5088-5p was performed with cellular fractionation assay and RNA pull-down assay, respectively. The involvement of SLC16A1-AS1 in miR-5088-5p maturation was studied with overexpression assay. BrdU assay was performed to detect cell proliferation after transfection. OSCC tissue samples exhibited decreased expression levels of SLC16A1-AS1 and premature miR-5088-5p, but increased the expression levels of mature miR-5088-5p. SLC16A1-AS1 was detected in both nucleus and cytoplasm samples of OSCC cells and its direct interaction with premature miR-5088-5p was confirmed. Overexpression of SLC16A1-AS1 in OSCC cells resulted in inhibited maturation of miR-5088-5p. SLC16A1-AS1 suppressed the enhancing effects of miR-5088-5p on cell proliferation. SLC16A1-AS1 was downregulated in OSCC and it may inhibit cell proliferation by suppressing maturation of miR-5088-5p.

Abstract
Plasma therapy and the study of the effects of cold atmospheric plasma (CAP) on tissues and living cells have been considered by scientific researchers in recent years. CAP is used in the treatment of cancer, but its anti-cancer mechanism has not been fully studied. Therefore, we studied the toxicity effect of CAP by using argon as feed gas and the synergistic effects of CAP with cisplatin on tumor cells and mitochondria isolated from tumor legions of the rat model of oral squamous cell carcinoma (OSCC). For this reason, we determined the possible toxic alterations of CAP on mitochondrial upstream events and activation of caspase-3 as the key major downstream event of apoptosis. Also, the effects of cisplatin (10 µM) as a positive control and its synergistic effects with CAP (IC50 concentration) were investigated. The results showed that CAP reduced mitochondrial dysfunction by reduction in succinate dehydrogenase (SDH) activity. Also, CAP in concentrations of 1200, 2400, and 4800 a.u. has been able to increase the level of reactive oxygen species (ROS), mitochondrial swelling, damage to the mitochondrial membrane, cytochrome c release, and activation of the final mediator of apoptosis (caspase-3) only in the OSCC group. CAP at 4800 a.u concentration had similar effects to cisplatin (10 µM). Synergistic effects between CAP (2400 a.u) and cisplatin (10 µM) have also been reported. Based on all results CAP showed positive and promising results on mitochondrial upstream parameters leading to activation of caspase-3, the final mediator of apoptosis only on OSCC cells and mitochondria without any significant effect on normal cells and mitochondria.

Abstract
Simple Summary Feline oral squamous cell carcinoma (FOSCC) is the most common oral neoplasia in cats. This malignant tumor is locally invasive, has a high mortality rate, and its etiology is not yet known. A critical review about the potential etiologic factors of FOSCC was performed, considering publications between 2000 and 2022. The initial search resulted in 553 publications, with only 26 of these being included in the review. Sixteen studies were related to viral etiology and nine related to environmental factors such as exposure to tobacco smoke, ectoparasitic products, and the presence of oral comorbidities. When evaluated, feline papillomavirus was detected in 16.2% of samples of FOSCC. In the three studies focused on exposure to tobacco smoke, 35.2% (30/85) of cats with FOSCC had a history of this exposure. Among 485 cats with FOSCC, 6.4% had dental and oral pathology. The present study demonstrates that the available evidence on the etiology of FOSCC is still limited, however, there has been increasing interest in this topic. Abstract Feline oral squamous cell carcinoma (FOSCC) is the most common oral neoplasia in cats. This malignant tumor is locally invasive, has a high mortality rate, and its etiology is not yet known. In humans, head and neck squamous cell carcinoma is associated with tobacco smoke, alcohol consumption, and human papillomavirus infection. Herein, a critical review about the potential etiologic factors of FOSCC was performed, considering publications between 2000 and 2022, aiming to synthesize all available scientific evidence regarding this issue. Recommendations of the PRISMA statement and the Cochrane Collaboration were followed and the PubMed database searched by using the MeSH terms MeSH terms “oral”, “mouth”, “lingual”, “labial”, “gingiva”, “carcinoma”, “squamous”, and “feline”. The selection process for eligible studies was based on specific inclusion and exclusion criteria and the quality of the studies assessed. The initial search resulted in 553 publications, with only 26 of these being included in the review. Sixteen studies were related to viral etiology and nine related to environmental factors such as exposure to tobacco smoke, ectoparasitic products, and the presence of oral comorbidities. When evaluated, feline papillomavirus was detected in 16.2% of samples of FOSCC. In the three studies focused on exposure to tobacco smoke, 35.2% (30/85) of cats with FOSCC had a history of this exposure. The consumption of canned food and the use of deworming collars were associated, in only one publication, with a risk of neoplasia increased by 4.7 and 5.3 times, respectively. Among 485 cats with FOSCC, 6.4% had dental and oral pathology (i.e., periodontal disease or feline chronic gingivostomatitis). The present study demonstrates that the available evidence on the etiology of FOSCC is still limited, however, there has been an increasing interest on this topic. To better understand the role of the possible etiological factors of this aggressive disease, and model for its human counterpart, large, prospective multi-institutional studies are needed.

Abstract
Long non-coding RNA FAM230B and microRNA (miR-1182) have been characterized as critical players in cancer biology, while their roles in colorectal cancer (CRC) are unclear. We predicted that they could interact with each other and therefore explored the interaction between them in CRC. CRC and paired non-tumor tissue samples were collected from 60 CRC patients, and the expression of FAM230B and miR-1182 (premature and mature) in these samples was analyzed with RT-qPCR. The direct interaction between FAM230B and premature miR-1182 was analyzed with RNA-RNA pull-down assay, and the subcellular location of FAM230B was detected with subcellular fractionation assay. The interaction between FAM230B and miR-1182 was explored with overexpression assay, and their roles in regulating CRC cell proliferation, viability, and colony formation were assessed by BrdU assay, MTT assay, and colony formation assay, respectively. We found that FAM230B and premature miR-1182 were highly upregulated in CRC, while mature miR-1182 was downregulated in CRC. FAM230B was detected in both nucleus and cytoplasm, and it directly interacted with miR-1182. FAM230B overexpression increased the expression levels of premature miR-1182 but decreased the expression levels of mature miR-1182 in CRC cells. FAM230B promoted CRC cell proliferation, increased cell viability, accelerated colony formation, and suppressed the role of miR-1182 in inhibiting CRC cell proliferation. In conclusion, FAM230B is upregulated in CRC and it suppresses the maturation of miR-1182 to promote tumor growth.

Abstract
BACKGROUND Tobacco use is the leading preventable cause of cancer and cancer deaths. Tobacco use is not only related to lung cancer, but has an impact on a wide range of different cancer entities in almost every organ system. OBJECTIVES The aim of this review article is to shed light on the different organ systems involved in tobacco-associated carcinogenesis. MATERIALS AND METHODS For this purpose, first a brief introduction into the topic is given, followed by a detailed description of the different tumor entities associated with tobacco use. RESULTS Tobacco consumption has been clearly implicated in the causation of many types of cancer, affecting multiple organ systems. Based on current evidence, tobacco use can cause cancer of the mouth and throat, larynx, esophagus, stomach, kidney, pancreas, liver, bladder, cervix, colon and rectum, and acute myeloid leukemia. CONCLUSION Tobacco use is not only main cause in the development of lung cancer, but has a major impact in the development of cancer in other organ systems. Therefore, special attention must be given to possible concomitant malignancies when evaluating images of smokers.

Immunotherapy for the Treatment of Squamous Cell Carcinoma: Potential Benefits and Challenges. Int J Mol Sci 2022; 23:ijms23158530. [PMID: 35955666 PMCID: PMC9368833 DOI: 10.3390/ijms23158530] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2022] [Revised: 07/26/2022] [Accepted: 07/29/2022] [Indexed: 02/01/2023] Open
Abstract
Melanoma and nonmelanoma skin cancers (NMSCs) are recognized as among the most common neoplasms, mostly in white people, with an increasing incidence rate. Among the NMSCs, squamous cell carcinoma (SCC) is the most prevalent malignancy known to affect people with a fair complexion who are exposed to extreme ultraviolet radiation (UVR), have a hereditary predisposition, or are immunosuppressed. There are several extrinsic and intrinsic determinants that contribute to the pathophysiology of the SCC. The therapeutic modalities depend on the SCC stages, from actinic keratosis to late-stage multiple metastases. Standard treatments include surgical excision, radiotherapy, and chemotherapy. As SCC represents a favorable tumor microenvironment with high tumor mutational burden, infiltration of immune cells, and expression of immune checkpoints, the SCC tumors are highly responsive to immunotherapies. Until now, there are three checkpoint inhibitors, cemiplimab, pembrolizumab, and nivolumab, that are approved for the treatment of advanced, recurrent, or metastatic SCC patients in the United States. Immunotherapy possesses significant therapeutic benefits for patients with metastatic or locally advanced tumors not eligible for surgery or radiotherapy to avoid the potential toxicity caused by the chemotherapies. Despite the high tolerability and efficiency, the existence of some challenges has been revealed such as, resistance to immunotherapy, less availability of the biomarkers, and difficulty in appropriate patient selection. This review aims to accumulate evidence regarding the genetic alterations related to SCC, the factors that contribute to the potential benefits of immunotherapy, and the challenges to follow this treatment regime.

Abstract
BACKGROUND Impact and efficiency of oral cancer and oral potentially malignant disorders screening are most realized in "at-risk" individuals. However, tools that can provide essential knowledge on individuals' risks are not applied in risk-based screening. This study aims to optimize a simplified risk scoring system for risk stratification in organized oral cancer and oral potentially malignant disorders screening. METHODS Participants were invited to attend a community-based oral cancer and oral potentially malignant disorders screening program in Hong Kong. Visual oral examination was performed for all attendees and information on sociodemographic characteristics as well as habitual, lifestyle, familial, and comorbidity risk factors were obtained. Individuals' status of those found to have suspicious lesions following biopsy and histopathology were classified as positive/negative and this outcome was used in a multiple logistic regression analysis with variables collected during screening. Odds ratio weightings were then used to develop a simplified risk scoring system which was validated in an external cohort. RESULTS Of 979 participants, 4.5% had positive status following confirmatory diagnosis. A 12-variable simplified risk scoring system with weightings was generated with an AUC, sensitivity, and specificity of 0.82, 0.71, and 0.78 for delineating high-risk cases. Further optimization on the validation cohort of 491 participants yielded a sensitivity and specificity of 0.75 and 0.87 respectively. CONCLUSIONS The simplified risk scoring system was able to stratify oral cancer and oral potentially malignant disorders risk with satisfactory sensitivity and specificity and can be applied in risk-based disease screening.

Abstract
Carcinomas of the oral cavity and oropharynx belong among the ten most common malignancies in the human population. The prognosis of head and neck squamous cell carcinoma (HNSCC) is determined by the degree of invasiveness of the primary tumor and by the extent of metastatic spread into regional and distant lymph nodes. Moreover, the level of the perineural invasion itself associates with tumor localization, invasion's extent, and the presence of nodal metastases. Here, we summarize the current knowledge about different aspects of epigenetic changes, which can be associated with HNSCC while focusing on perineural invasion (PNI). We review epigenetic modifications of the genes involved in the PNI process in HNSCC from the omics perspective and specific epigenetic modifications in OSCC or other neurotropic cancers associated with perineural invasion. Moreover, we summarize DNA methylation status of tumor-suppressor genes, methylation and demethylation enzymes and histone post-translational modifications associated with PNI. The influence of other epigenetic factors on the HNSCC incidence and perineural invasion such as tobacco, alcohol and oral microbiome is overviewed and HPV infection is discussed as an epigenetic factor associated with OSCC and related perineural invasion. Understanding epigenetic regulations of axon growth that lead to tumorous spread or uncovering the molecular control of axon interaction with cancer tissue can help to discover new therapeutic targets for these tumors.

Abstract
Oral cancer is a globally widespread cancer that features among the three most prevalent cancers in India. The risk of oral cancer is elevated by factors such as tobacco consumption, betel-quid chewing, excessive alcohol consumption, unhygienic oral condition, sustained viral infections, and also due to dysbiosis in microbiome composition of the oral cavity. Here, we performed an oral microbiome study of healthy and oral cancer patients to decipher the microbial dysbiosis due to the consumption of smokeless-tobacco-based products and also revealed the tobacco-associated microbiome. The analysis of 196 oral microbiome samples from three different oral sites of 32 healthy and 34 oral squamous cell carcinoma (OSCC) patients indicated health status, site of sampling, and smokeless tobacco consumption as significant covariates associated with oral microbiome composition. Significant similarity in oral microbiome composition of smokeless-tobacco-consuming healthy samples and OSCC samples inferred the possible role of smokeless tobacco consumption in increasing inflammation-associated species in oral microbiome. Significantly higher abundance of Streptococcus was found to adequately discriminate smokeless-tobacco-non-consuming healthy samples from smokeless-tobacco-consuming healthy samples and contralateral healthy site of OSCC samples from the tumor site of OSCC samples. Comparative analysis of oral microbiome from another OSCC cohort also confirmed Streptococcus as a potential marker for healthy oral microbiome. Gram-negative microbial genera such as Prevotella, Capnocytophaga, and Fusobacterium were found to be differentially abundant in OSCC-associated microbiomes and can be considered as potential microbiome marker genera for oral cancer. Association with lipopolysaccharide (LPS) biosynthesis pathway further confirms the differential abundance of Gram-negative marker genera in OSCC microbiomes.

Abstract
Oral cancer is a common site of cancer worldwide with oral squamous cell carcinoma (OSCC) comprising the major segment. The risk factors include tobacco and alcohol abuse, betel quid, and areca nut consumption. Warthin tumour (WT), also known as papillary cystadenoma lymphomatosum is a benign tumour of the salivary gland. It is one of the most common benign parotid neoplasms with cigarette smoking and radiation exposure as possible cited etiologic factors. Rarely, two or more histologically distinct neoplasms may occur synchronously. The synchronous occurrence of OSCC and WT is infrequent. The aim of this case series is to report the incidence rate of synchronous OSCC and WT in our centre between 2010 and 2019 and their socio-demographic, clinical, histopathological features, management, and prognosis and discuss the relevant literature. Out of 143 OSCC cases reported in our centre from the year 2010 to 2019, two had synchronous OSCC and WT with an incidence rate of 1.4%. These two cases occurred in a 63-year-old female and a 68-year-old male both with smoking habits. One OSCC was present in the left buccal mucosa and the other in the right ventral surface of the tongue, whereas the WT in both cases occurred in the tail of the parotid. One patient had a recurrence and died while the other is under follow-up without any recurrence. These unusual findings of synchronous occurrence of WT at a distant site from the primary tumour may mimic a malignant disease, more likely a metastasis from the primary OSCC, which could further complicate the management of these patients. Therefore, radiologists, head and neck surgeons, and pathologists should be aware of the occurrence of these unusual presentations to avoid overtreatment in such cases.

Abstract
Oral cancer is the eighth greatest generally diagnosed cancer amongst males worldwide and the fourth most generally malignancy amongst Taiwanese males. The pro-inflammatory adipocytokine visfatin promotes tumor growth. Elevated plasma visfatin levels have been identified in patients with oral squamous cell carcinoma (OSCC), although the biological mechanisms underlying the involvement of visfatin in the pathogenesis of OSCC are not well understood. Moreover, no information is available regarding associations between visfatin polymorphisms and carcinogenic lifestyle factors with OSCC. This study, therefore, investigated the effects of four visfatin gene polymorphisms (rs11977021, rs61330082, rs2110385, and rs4730153) and carcinogenic lifestyle factors (betel nut chewing, alcohol consumption and cigarette smoking) on the risk of developing OSCC in 1,275 Taiwanese males with OSCC, and 1,195 healthy males (controls). We also examined the associations between these visfatin genotypes and OSCC histopathological prognostic factors (pathological stage, tumor status, lymph node status, and metastasis). We found that compared with subjects with the CC genotype of SNP rs11977021, those with the CT+TT genotype were less likely to progress OSCC. In addition, an association was found between the rs4730153 variant and lymph node metastasis in the OSCC cohort.

Abstract
BACKGROUND Human papillomavirus (HPV) is one of the most common sexually transmitted infection in the United States and can lead to cervical, vulvovaginal, anal, penile, and oropharyngeal cancers. Compared with the general population, US military members are at a higher risk of HPV-related conditions, yet vaccination rates are relatively low in this population. As many service members may not be diagnosed with HPV-related cancers until after they leave active service, the objective of this study was to determine the incidence, prevalence, and economic burden of HPV-related cancers among US veterans. METHODS The study used the 2014-2018 Veterans Health Administration (VHA) database to identify newly diagnosed adult patients (cases) with HPV-related cancers, including cervical, vulvovaginal, anal, penile, and oropharyngeal cancers. Cases were matched by age, race, and sex to patients without HPV related cancer (controls). Outcome measures included annual incidence, prevalence, health care resource utilization (HCRU), and costs. These outcomes were calculated from the index date (first cancer diagnosis) through the earliest of 24 months, death, or end of study period. Adjusted results were examined using generalized linear models. RESULTS The annual prevalence and incidence rates of HPV-related cancers ranged from 43 (anal) to 790 (oropharyngeal) cases per million (CPM), and four (anal) to 131 (cervical) CPM, respectively. Compared with controls, cases had significantly higher annual HCRU. Mean numbers of annual inpatient hospitalizations were several times higher compared to controls (cervical: 6.7-times (×); vulvovaginal: 2.7×; penile: 6.6×; oropharyngeal: 10.2×; and anal: 14.9×; all p < 0.01). Similarly, cases had significantly higher all-cause healthcare costs vs. matched controls across all cancer types: cervical ($24,252 vs. $10,402), vulvovaginal ($34,801 vs. $10,913), penile ($42,772 vs. $9,139), oropharyngeal ($82,763 vs. $10,017), and anal ($98,146 vs. $8,339); (all p < 0.01). CONCLUSIONS HPV-related cancers may cause significant clinical and economic burden within the VHA system. Given the consequences of HPV-related cancers among veterans who did not have access to the vaccine, HPV vaccination of active military and eligible veterans should be considered a healthcare priority.

Abstract
Oral squamous cell carcinoma (OSCC) predominantly consists of squamous cells and is the tumor with the highest incidence of the head and neck. Carnosic acid (CA), a natural monomer drug obtained from rosemary and salvia, shows various pharmacological effects, including of tumor development. This study aimed to assess for an effect of CA on the development of OSCC and the underlying mechanisms. In CAL27 and SCC9 cells, CA inhibited cell proliferation and migration, increased intracellular levels of reactive oxygen species (ROS) and Ca2+, decreased the mitochondrial membrane potential (MMP), and promoted apoptosis. In CAL27- and SCC9-xenotransplanted BALB/c nude mice, CA inhibited the tumor growth without affecting the body weight and tissue morphology. CA upregulated Bax, Bad, cleaved Caspase-3 and -9 levels, and the cleaved PARP1/PARP1 ratio but downregulated Bcl-2 in CA-treated OSCC cells and OSCC cells-xenotransplanted BALB/c nude mice. These results indicate that CA suppresses OSCC at least via the mitochondrial apoptotic pathway and offers this natural compound as a potential therapeutic against OSCC.

Oral cancer among Khat users: finding evidence from DNA analysis of nine cancer-related gene mutations. BMC Oral Health 2021; 21:626. [PMID: 34876124 PMCID: PMC8650367 DOI: 10.1186/s12903-021-01981-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2021] [Accepted: 11/22/2021] [Indexed: 01/18/2023] Open
Abstract
BACKGROUND Khat leaves contain the alkaloid cathinone. Research shows that khat might provoke toxicity, mutagenicity, as well as carcinogenicity. METHODS Two groups were identified as khat abusers and were categorized by abuse time and diagnosis of oral squamous cell carcinoma (OSCC). Here, 41 participants from Group 2 were short-term khat users, and 42 participants were long-term khat users. The control group included 30 healthy individuals. The coding exons included nine cancer-related genes and were analysed. The histopathological research was conducted with H&E staining along with the TP53 protein expression by implementing immunohistochemical analyses. RESULTS Here, 41 short-term khat users carried seven somatic mutations in four out of nine cancer-related genes: 29/41(70.73%) ARID1A, 24/41(58.53%) MLH1, 34/41(82.92%) PIK3CA and 36/41(87.80%) TP53. The 42 long-term khat users incorporated nine somatic mutations in five out of nin ecancer-related genes: 40/42(95.23%) ARID1A, 36/42(85.71%) ARID2, 29/42(69.04%) PIK3CA, 27/42(64.28%) MLH1, and 35/42(83.33%) TP53. Every khat user had somatic mutations related to OSCC affecting the gingiva and the lower lip. TP53 protein expression was confirmed in all immunohistochemical oral tests. Carcinoma was also positive in the histopathological analysis. CONCLUSIONS Khat is a mutagenic and carcinogenic plant that provoked OSCC among short-term khat users (<15 years of use) and long-term users (>15 years of use).

Development and Validation of Prognostic Models for Oral Squamous Cell Carcinoma: A Systematic Review and Appraisal of the Literature. Cancers (Basel) 2021; 13:cancers13225755. [PMID: 34830913 PMCID: PMC8616042 DOI: 10.3390/cancers13225755] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2021] [Revised: 11/08/2021] [Accepted: 11/13/2021] [Indexed: 12/23/2022] Open
Abstract
(1) Background: An accurate prediction of cancer survival is very important for counseling, treatment planning, follow-up, and postoperative risk assessment in patients with Oral Squamous Cell Carcinoma (OSCC). There has been an increased interest in the development of clinical prognostic models and nomograms which are their graphic representation. The study aimed to revise the prognostic performance of clinical-pathological prognostic models with internal validation for OSCC. (2) Methods: This systematic review was performed according to the Cochrane Handbook for Diagnostic Test Accuracy Reviews chapter on searching, the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines, and the Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modelling Studies (CHARMS). (3) Results: Six studies evaluating overall survival in patients with OSCC were identified. All studies performed internal validation, while only four models were externally validated. (4) Conclusions: Based on the results of this systematic review, it is possible to state that it is necessary to carry out internal validation and shrinkage to correct overfitting and provide an adequate performance for optimism. Moreover, calibration, discrimination and nonlinearity of continuous predictors should always be examined. To reduce the risk of bias the study design used should be prospective and imputation techniques should always be applied to handle missing data. In addition, the complete equation of the prognostic model must be reported to allow updating, external validation in a new context and the subsequent evaluation of the impact on health outcomes and on the cost-effectiveness of care.

Abstract
BACKGROUND Squamous cell carcinoma (SCC) describes the carcinomatous growth in the oral cavity. Recently, various authors have described increased SCC incidence in the young population. The distribution of SCC shows varied geographic spread, with the highest distribution in Asian countries. AIMS The present trial was carried out to assess the associated factors that could lead to increased risk of developing oral cancer. MATERIALS AND METHODS Oral examination was carried out for 21 participants by a dentist and any significant oral lesion or deleterious habit if present, was recorded. The data collected were analyzed. RESULTS Areca nut was chewed by 47.61% participants (n = 10), smoking tobacco by 76.19% (n = 16), chewing tobacco by 38.09% (n = 8), and consuming alcohol in 9 participants (42.85%). No significant difference was seen concerning age for any factor except alcohol which showed higher intake in the older group where six participants depicted alcohol intake as compared to three participants in the younger group. In participants who chewed areca nuts, 6 participants also smoked tobacco and 1 consumed alcohol. For tobacco chewing, 5 consumed alcohol and 6 also took tobacco as smoke. CONCLUSION The present study showed that areca nut and tobacco chewing along with alcohol consumption and tobacco smoking increase the risk of developing SCC in the Indian population.

Cancer Cell Int 2021; 21:578. [PMID: 34717640 PMCID: PMC8557586 DOI: 10.1186/s12935-021-02276-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2021] [Accepted: 10/18/2021] [Indexed: 12/02/2022] Open
Abstract
Background Cigarette smoking is the most significant cause of oral cancer progression. Cigarette smoke condensate (CSC) has been shown to induce endoplasmic reticulum (ER) stress. Binding immunoglobulin protein (BiP) being as an ER stress regulator, has been reported to be implicated in malignant behaviors. Therefore, the aim of this study was to investigate the role of the ER stress-responsive protein, BiP, in CSC-induced oral squamous cell carcinoma (OSCC) malignancy. Methods The biological role of BiP in CSC-induced tumor progression was investigated in OSCC cells (YD38 and SCC25) and in a tumor xenograft mouse model. The expressions of related genes were investigated using quantitative RT-PCR and Western blot analysis. Cell migration and invasion were assessed using scratch wound healing and Transwell invasion assays. The effects of conditioned media from OSCC cells on the angiogenic activities of endothelial cells were analyzed using a tube formation assay. The interaction between miR-30a and BiP mRNA was detected using a luciferase reporter assay. Results Our results demonstrated that CSC increased the expression of BiP in time- and dose-dependent manners in YD38 and SCC25 cells, and that silencing BiP abrogated CSC-induced cell invasion and tumor-associated angiogenesis. Notably, the putative miR-30a binding site was observed in the 3′untranslated region (UTR) of BiP mRNA, and miR-30a suppressed BiP expression by targeting 3′UTR of BiP transcript. In addition, CSC increased the expression of BiP in OSCC cells by downregulating miR-30a. We also showed that BiP promoted invasion and tumor-associated angiogenesis by increasing the production and secretion of vascular endothelial growth factor in CSC-exposed OSCC cells. Moreover, BiP inhibition suppressed OSCC growth and reduced tumor vessel density in tumor-bearing mice administered with CSC. Conclusions These observations suggest that epigenetic regulation of BiP via miR-30a downregulation is involved in CSC-induced OSCC progression.

Abstract
Aberrant protein glycosylation is known to be associated with the development of various cancers. Although fucosylation is essential for normal biological functions, alterations in fucosylation are strongly implicated in cancer and increasing metastatic potential. Altered fucosyltarnsferases (FUTs) and fucosidases are found to be involved in many types of malignancies. In this study, we examined the mRNA expressions of fucosidase (FUCA1) and FUTs (FUTs (FUT3, FUT4, FUT5, FUT6, FUT8) in human oral cancer tissues. All FUTs and FUCA1 were significantly (P ≤0.05) down-regulated in malignant tissues in comparison with their adjacent normal tissues. The relationship between the clinicopathological parameters and the expression of FUTs and FUCA1 revealed that higher mRNA levels of FUT4, FUT5, and FUT8 and lower levels of FUT3 were associated with progression of disease and lymph node metastasis in oral carcinoma indicating their role in oral cancer progression. Collectively, results suggest that elevated mRNA levels of FUT4, FUT5 and FUT8 may be used as worst prognostic indicators for oral carcinoma.

Ann Med Surg (Lond) 2021; 69:102820. [PMID: 34527241 PMCID: PMC8429914 DOI: 10.1016/j.amsu.2021.102820] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2021] [Revised: 08/27/2021] [Accepted: 09/03/2021] [Indexed: 11/23/2022] Open
Abstract
Introduction importance: Gingival squamous cell carcinoma (GSCC) is a rare neoplasm. GSCC has nonspecific features which commonly misdiagnosed with a simple toothache. Case presentation These are two cases; the first one describes a 62-year-old female who presented with pain in her right posterior mandibular teeth, and she was misdiagnosed with periodontal disease, but later histopathological tests confirmed gingival squamous cell carcinoma (GSCC). Consequently, the patient underwent surgery, and the gingival tumor was totally resected. Afterward, the patient was receiving chemotherapy, and the radiotherapy was postponed until the chemotherapy completion. The second case is of a 58-year-old female who presented with pain in her mandibular incisors, and she developed a dermal fistula on her chin and therefore underwent several gingival curettages. The following histopathologic tests confirmed GSCC so she underwent surgery, after the surgery it was planned to give her chemotherapy. Clinical discussion GSCC is a rare neoplasm with a 6% incidence of all oral malignancies. GSCC is a very challenging cancer for a physician or a pathologist to diagnose because GSCC usually mimics the characteristics of a large variety of diseases and abnormalities. Unlike oral neoplasms, GSCC has the least association with smoking. This may lead to make mistakes in the treatment or misdiagnose it until the late-stage of GSCC. Conclusion Despite the rare incidence of Gingival squamous cell carcinoma (GSCC), clinicians should consider GSCC while investigating any localized lesion with nonspecific oral symptoms. GSCC usually presents with non-specific symptoms. Doctors should think of GSCC as a probable diagnosis of oral lesions with vague presentation. Suspicious oral lesions should be biopsied as soon as possible. The primary or metastatic malignancy must be surgically removed.

Abstract
Cigarette smoking is a significant risk factor for the development and progression of oral cancer. Previous studies have reported an association between nicotine and malignancy in oral cancer. Recent studies have also demonstrated that nicotine can induce endoplasmic reticulum (ER) stress in tumor cells. Binding immunoglobulin protein (BiP) acts as a master regulator of ER stress and is frequently overexpressed in oral cancer cell lines and tissues. However, the effect of nicotine on BiP in oral cancer is unknown. Therefore, this study aimed to evaluate the role of BiP and its underlying regulatory mechanisms in nicotine-induced oral cancer progression. Our results showed that nicotine significantly induced the expression of BiP in time- and dose-dependent manners in oral squamous cell carcinoma (OSCC) cells. In addition, BiP was involved in nicotine-mediated OSCC malignancy, and depletion of BiP expression remarkably suppressed nicotine-induced malignant behaviors, including epithelial-mesenchymal transition (EMT) change, migration, and invasion. In vivo, BiP silencing abrogated nicotine-induced tumor growth and EMT switch in nude mice. Moreover, nicotine stimulated BiP expression through the activation of the YAP-TEAD transcriptional complex. Mechanistically, we observed that nicotine regulated YAP nuclear translocation and its interaction with TEAD through α7-nAChR-Akt signaling, subsequently resulting in increased TEAD occupancy on the HSPA5 promoter and elevated promoter activity. These observations suggest that BiP is involved in nicotine-induced oral cancer malignancy and may have therapeutic potential in tobacco-related oral cancer.

BMC Public Health 2021; 21:1419. [PMID: 34275456 PMCID: PMC8286564 DOI: 10.1186/s12889-021-11477-2] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2021] [Accepted: 06/28/2021] [Indexed: 11/10/2022] Open
Abstract
INTRODUCTION Only one-quarter of smokers in Pakistan attempt to quit smoking, and less than 3% are successful. In the absence of any literature from the country, this study aimed to explore factors motivating and strategies employed in successful smoking cessation attempts in Pakistan, a lower-middle-income country. METHODS A survey was carried out in Karachi, Pakistan, amongst adult (≥ 18 years) former smokers (individuals who had smoked ≥100 cigarettes in their lifetime but who had successfully quit smoking for > 1 month at the time of survey). Multivariable logistic regression, with number of quit attempts (single vs. multiple) as the dependent variable, was performed while adjusting for age, sex, monthly family income, years smoked, cigarettes/day before quitting, and having suffered from a smoking-related health problem. RESULTS Out of 330 former smokers, 50.3% quit successfully on their first attempt with 62.1% quitting "cold turkey". Only 10.9% used a cessation aid (most commonly nicotine replacement therapy: 8.2%). Motivations for quitting included self-health (74.5%), promptings by one's family (43%), and family's health (14.8%). Other social pressures included peer-pressure to quit smoking (31.2%) and social avoidance by non-smokers (22.7%). Successful smoking cessation on one's first attempt was associated with being married (OR: 4.47 [95% CI: 2.32-8.61]), employing an abrupt cessation mode of quitting (4.12 [2.48-6.84]), and telling oneself that one has the willpower to quit (1.68 [1.04-2.71]). CONCLUSION In Pakistan, smoking cessation is motivated by concern for self-health and family's health, family's support, and social pressures. Our results lay a comprehensive foundation for the development of smoking-cessation interventions tailored to the population of the country. IMPLICATIONS Little is known about the patterns and strategies employed by smokers who are attempting to quit smoking, especially in lower-middle-income countries like Pakistan. Likewise, there are very few smoking cessation programs designed to assist in quitting. Our study will allow for a better understanding of the culture-specific motivating factors and strategies that most contributed to successful quit attempts. Based on these results, evidence based smoking cessation interventions can be developed tailored to the socioeconomic demographic of our country and region, including smoking cessation clinics and public outreach and media campaigns highlighting key elements of successful smoking cessation.
