Testa A, Jackson DB, Gutierrez C, Fahmy C, Maroufy V, Samper-Ternent R, Neumann AC. History of Incarceration and Dental Care Use Among Older Adults in the United States. Am J Prev Med 2024:S0749-3797(24)00223-X. [PMID: 38960292 DOI: 10.1016/j.amepre.2024.06.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2024] [Revised: 06/26/2024] [Accepted: 06/26/2024] [Indexed: 07/05/2024]
Abstract
INTRODUCTION Dental care is a critical component of healthy aging; however, emerging evidence suggests that having been previously incarcerated is a risk factor for not using dental care services. This study investigates the relationship between prior incarceration and dental care among older adults and assesses whether wealth and dental insurance explain this relationship. METHODS Data are from the Health and Retirement Study, a nationally representative sample of community-dwelling older adults in the United States, collected in 2012 and 2014. Multivariable logistic regression is used to assess the relationship between a history of incarceration and dental care. Mediation analyses were conducted using the Karlson-Holm-Breen method of indirect effects in non-linear models. Statistical analyses were conducted from February to April 2024. RESULTS Adjusting for potential confounding variables, a respondent's prior incarceration is associated with a 25% lower odds of dental care use (adjusted odds ratio [aOR] = 0.748, 95% CI = 0.624, 0.896). The relationship between incarceration and dental care use is fully mediated-over 90% is explained by-wealth and having dental care insurance. Prior incarceration decreased the likelihood of dental care only among non-Hispanic White respondents. CONCLUSIONS The findings offer new evidence that prior incarceration is a risk factor for lacking the ability to utilize dental care among older adults and suggest that broader consequences of incarceration for wealth accumulation and access to dental insurance underpin this relationship. These results suggest the urgent need to expand access to affordable dental care services for older adults with a history of incarceration.

[PMID: 38689995 PMCID: PMC11059418 DOI: 10.1016/j.heliyon.2024.e28005] [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: 06/21/2023] [Revised: 03/08/2024] [Accepted: 03/11/2024] [Indexed: 05/02/2024] Open
Abstract
ARPC1B encodes the protein known as actin-related protein 2/3 complex subunit 1 B (ARPC1B), which controls actin polymerization in the human body. Although ARPC1B has been linked to several human malignancies, its function in these cancers remains unclear. TCGA, GTEx, CCLE, Xena, CellMiner, TISIDB, and molecular signature databases were used to analyze ARPC1B expression in cancers. Visualization of data was primarily achieved using R language, version 4.0. Nineteen tumors exhibited high levels of ARPC1B expression, which were associated with different tumor stages and significantly affected the prognosis of various cancers. The level of ARPC1B expression substantially connected the narrative of ARPC1B expression with several TMB cancers and showed significant changes in MSI. Additionally, tolerance to numerous anticancer medications has been linked to high ARPC1B gene expression. Using Gene Set Variation Analysis/Gene Set Enrichment Analysisanalysis and concentrating on Rectum adenocarcinoma (READ), we thoroughly examined the molecular processes of the ARPC1B gene in pan-cancer. Using WGCNA, we examined the co-expression network of READ and ARPC1B. Meanwhile, ten specimens were selected for immunohistochemical examination, which showed high expression of ARPC1B in READ. Human pan-cancer samples show higher ARPC1B expression than healthy tissues. In many malignancies, particularly READ, ARPC1B overexpression is associated with immune cell infiltration and a poor prognosis. These results imply that the molecular biomarker ARPC1B may be used to assess the prognosis and immune infiltration of patients with READ.

Abstract
BACKGROUND Recent studies have indicated that microRNA (miRNA) expression in tumour tissues has prognostic significance in Tongue squamous cell carcinoma (TSCC) patients. This study explored the possible prognostic value of miRNAs for TSCC based on published research. METHODS A comprehensive literature search of multiple databases was conducted according to predefined eligibility criteria. Data were extracted from the included studies by two researchers, and HR results were determined based on Kaplan‒Meier curves according to the Tierney method. The Newcastle‒Ottawa Scale (NOS) and GRADE (Grading of Recommendations Assessment, Development, and Evaluation) pro-GDT were applied to assess the quality of all studies. Publication bias was estimated by funnel plot, Egger's rank correlation test and sensitivity analysis. RESULTS Eleven studies (891patients) were included, of which 6 reported up-regulated miRNAs and 7 mentioned down-regulated miRNAs. The pooled hazard ratio (HR) from the prognostic indicator overall survival (OS) was 1.34 (1.25-1.44), p < 0.00001, indicating a significant difference in miRNA expression between TSCC patients with better or worse prognosis. CONCLUSION MiRNAs may have high prognostic value and could be used as prognostic biomarkers of TSCC.

Abstract
INTRODUCTION The dentist should be able to carry out systematic oral examinations of the mucosa of patients in order to diagnose any alterations at an early stage. MATERIALS AND METHODS An observational, analytical, prospective, and longitudinal study was carried out. 161 students were evaluated at the beginning of their clinical practice in their 4th year of dental school (September 2019), at the beginning and at the end of their 5th year of dental school (June 2021). Thirty oral lesions were projected, and the students were asked to provide an answer; if the lesions were benign, malignant, or potentially malignant, whether they should be biopsied and/or treated and a presumptive diagnosis. RESULTS Significant improvement (p < .001) was obtained between the 2019 and 2021 results, in relation to the classification, need for biopsy and treatment of lesions. For differential diagnosis, no significant difference (p = .985) was obtained between the 2019 and 2021 responses. Malignant lesions and PMD obtained mixed results, with the best results corresponding to OSCC. DISCUSSION In this study, a correct lesion classification by the students was over 50%. As for the OSCC, the results were superior to the rest of the images, reaching more than 95% correct. CONCLUSION Theoretical-practical training from universities and continuing education for graduates in relation to oral mucosal pathologies should be further promoted.

Abstract
OBJECTIVE Gossypetin, isolated from Hibiscus sabdariffa L, has been shown to have various pharmacological effects including anti-inflammatory and antibacterial activity against various diseases. However, since the effect of gossypetin in oral cancer remains to be reported, we aimed to investigate the anticancer activity and mechanisms of gossypetin in oral squamous cell carcinoma (OSCC). METHODOLOGY The proliferation of OSCC cells was evaluated by cell viability and soft agar colony assays. The effects of gossypetin on the migration and invasion of OSCC cells was investigated by wound healing and transwell invasion assays, respectively. Apoptosis and cell cycle arrest were measured by flow cytometry. Moreover, the anticancer mechanism of gossypetin in OSCC cells was analyzed by western blotting. RESULTS Gossypetin inhibited the proliferation, migration, and invasion of OSCC cells and induced apoptosis by upregulating the Bax/Bcl-2 ratio and cell cycle arrest at the G2/M phase. Furthermore, gossypetin regulated the activation of extracellular signal-regulated kinase and nuclear factor-kappa B. CONCLUSION Results showed that gossypetin inhibits the proliferation, migration, and invasion of OSCC cells and triggers apoptosis and cell cycle arrest in OSCC. Therefore, gossypetin has the potential for use as a chemopreventive agent in oral cancer.

Indian J Otolaryngol Head Neck Surg 2023; 75:109-114. [PMID: 37007900 PMCID: PMC10050459 DOI: 10.1007/s12070-022-03200-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2022] [Accepted: 09/23/2022] [Indexed: 11/06/2022] Open
Abstract
Cancer stem cell marker CD44 is a cell-surface glycoprotein which is involved in various cellular functions such as cell-cell interactions, cell adhesion, haematopoiesis and tumour metastasis. The CD44 gene transcription is partly activated by beta-catenin and Wnt signalling pathway, the later pathway being linked to tumour development. However, the role of CD44 in oral squamous cell carcinoma (OSCC) is not well understood. We investigated the expression of CD44 in peripheral circulation, tumour tissues of oral cancer patients and oral squamous cell carcinoma cell lines by ELISA and quantitative (q)-RTPCR. Relative CD44s mRNA expression was significantly higher in peripheral circulation (p = 0.04), tumour tissues (p = 0.049) and in oral cancer cell lines (SCC4, SCC25 p = 0.02, SCC9 p = 0.03). Circulating CD44total protein levels were also significantly (p < 0.001) higher in OSCC patients that positively correlated with increasing tumour load and loco-regional spread of the tumour. The circulating tumour stem cell marker CD44 appears to be a potent indicator of tumour progression and may be useful for developing suitable therapeutics strategies for patients with oral squamous cell carcinoma.

Abstract
OBJECTIVE This systematic review aims to investigate possible connections between the oral microbiome and the onset and carcinogenesis of oral epithelial dysplasia (OED). METHODS A systematic search was performed on PubMed, Embase, Cochrane Database, and SCOPUS by two authors independently, addressing the focused question- "Has oral microbiome dysbiosis been involved in the onset and carcinogenesis of oral epithelial dysplasia?" We used the Newcastle-Ottawa scale to assess the quality of studies included in the review. RESULTS Out of 580 references screened, ten studies were found eligible for inclusion. All studies were case-control studies, and only qualitative analysis was conducted due to heterogeneous characteristics. The overall risk of bias in the eligible studies was considered as high. Microbiome diversity indices showed inconsistent evidence among studies. A significant increase of phylum Bacteroidetes in OED patients was reported in five studies. Five studies reported an increase of genus Fusobacterium in both the OED and oral squamous cell carcinoma (OSCC) patients and six different studies respectively reported a reduction of genus Streptococcus in both the OED and OSCC groups when compared to normal controls. Other predominant bacteria that were specific to different patient groups varied in each study. CONCLUSIONS The results of the included studies showed that the composition of the oral microbiome in patients with OED compared to healthy controls and OSCC patients was inconsistent. However, all ten studies showed non-negligible heterogeneity in the type and size of the sample, and the comparability between groups, which strongly limited the external validity of results. Further studies are strongly recommended.

Abstract
Oral cavity squamous cell carcinoma (OCSCC) is a well-recognized malignancy of the head and neck. Studies on patients with early-stage oral cancer have shown that they develop locally recurring and/or regional lymph node metastasis, which results in disease-associated mortality. Thus, early-stage oral cancer does not always present good prognoses. The present study aimed to determine the efficacy of using worst pattern of invasion (WPOI) and other histopathological features, such as prognostic factors in OCSCC, and analyze the impact of resection margin status and histopathological prognostic indicators on local recurrence (LR) and overall survival (OS) in patients with OCSCC. A retrospective cohort study was conducted by reviewing the charts of 63 patients with OCSCC treated with primary surgery at King Abdulaziz University Hospital between 2012 and 2019. An author and an experienced pathologist reviewed pathology slides. Associations of histopathological factors, including differentiation, stage, lymphovascular invasion, extracapsular extension, perineural invasion (PNI), WPOI and surgical margins, with LR or disease-free survival (DFS) were evaluated. Univariate analysis identified WPOI and PNI, and multivariate analysis identified the WPOI as predictive factors for LR and DFS. Kaplan-Meier analysis identified the WPOI and PNI as predictive factors for OS and WPOI as a predictive factor for DFS. Therefore, it may be concluded that WPOI and PNI are significant independent prognostic factors for local tumor control and DFS in patients with OCSCC.

Abstract
Oral squamous cell carcinoma (OSCC) is one of the most common (90%) types of oral carcinomas in the world. It is the 2nd most common and 3rd deadliest cancer in India. The lack of early detection marker is one of the major causes of worst prognosis. The vimentin belongs to intermediate filament family proteins which plays significant role in maintaining cellular integrity. Over-expression of vimentin has been widely reported in many epithelial cancers however the information regarding its prevalence in the oral cancers still needs further scientific intervention. The expression level of circulating vimentin protein in serum samples (n = 30) of oral submucous fibrosis (OSMF), OSCC patients and healthy controls were measured by performing ELISA. The serum level of vimentin was significantly higher in OSMF (p < 0.01) and OSCC (p < 0.003) patients as compared to healthy subjects. The circulating vimentin levels showed a gradual increase with increasing disease status (normal < OSMF < OSCC). Circulatory levels of vimentin may ba useful indicator of disease progression and as a suitable target for therapeutic intervention of oral submucous fibrosis and oral carcinoma.

Abstract
Curcumin is an active ingredient isolated from Curcuma longa. It has several pharmacological effects, including anticancer, anti-inflammatory, and antioxidant effects. Due to its low bioavailability, chemical structure instability, and easy oxidation, the application of curcumin has been limited. In this study, to overcome these limitations, curcumin-loaded mesoporous silica nanoparticles (Cur-MSN) were prepared, and the anticancerous effect of Cur-MSNs on head and neck cancer cells, HN5, was investigated. Transmission electron microscopy (TEM) revealed rod-shaped mesoporous nanoparticles with average particle size smaller than 100 nm. Higher cytotoxicity of Cur-MSNs was seen in treated cancer cells compared with free curcumin. The expression of Bcl-2 was significantly reduced in the presence of Cur-MSNs compared to the control (untreated HN5 cells) (p < 0.05). A 3.43-fold increase in the Bax/Bcl-2 ratio was seen in Cur-MSNs treated HN5 cells at the IC50. Cur-MSNs increased intracellular reactive oxygen species (ROS) production. Based on these novel results, we suggest that Cur-MSNs offer efficacy for cancer treatment and future studies should further characterize their properties in various experimental cancer models.

Abstract
Advanced-stage oral squamous cell carcinoma (OSCC) patients are treated with combination therapies, such as surgery, radiation, chemotherapy, and immunotherapy. However, OSCC cells acquire resistance to these treatments, resulting in local recurrence and distant metastasis. The identification of genes involved in drug resistance is essential for improving the treatment of this disease. In this study, we applied chromatin immunoprecipitation sequencing (ChIP-Seq) to profile active enhancers. For that purpose, we used OSCC cell lines that had been exposed to cetuximab for a prolonged period. In total, 64 chromosomal loci were identified as active super-enhancers (SE) according to active enhancer marker histone H3 lysine 27 acetylation (H3K27ac) ChIP-Seq. In addition, a total of 131 genes were located in SE regions, and 34 genes were upregulated in OSCC tissues by TCGA-OSCC analysis. Moreover, high expression of four genes (C9orf89; p = 0.035, CENPA; p = 0.020, PISD; p = 0.0051, and TRAF2; p = 0.0075) closely predicted a poorer prognosis for OSCC patients according to log-rank tests. Increased expression of the four genes (mRNA Z-score ≥ 0) frequently co-occurred in TCGA-OSCC analyses. The high and low expression groups of the four genes showed significant differences in prognosis, suggesting that there are clear differences in the pathways based on the underlying gene expression profiles. These data indicate that potential stratified therapeutic strategies could be used to overcome resistance to drugs (including cetuximab) and further improve responses in drug-sensitive patients.

Automatic discrimination of Yamamoto-Kohama classification by machine learning approach for invasive pattern of oral squamous cell carcinoma using digital microscopic images: a retrospective study. Oral Surg Oral Med Oral Pathol Oral Radiol 2022; 133:441-452. [PMID: 35165068 DOI: 10.1016/j.oooo.2021.10.004] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2021] [Revised: 09/02/2021] [Accepted: 10/06/2021] [Indexed: 10/20/2022]
Abstract
OBJECTIVE The Yamamoto-Kohama criteria are clinically useful for determining the mode of tumor invasion, especially in Japan. However, this evaluation method is based on subjective visual findings and has led to significant differences in determinations between evaluators and facilities. In this retrospective study, we aimed to develop an automatic method of determining the mode of invasion based on the processing of digital medical images. STUDY DESIGN Using 101 digitized photographic images of anonymized stained specimen slides, we created a classifier that allowed clinicians to introduce feature values and subjected the cases to machine learning using a random forest approach. We then compared the Yamamoto-Kohama grades (1, 2, 3, 4C, 4D) determined by a human oral and maxillofacial surgeon with those determined using the machine learning approach. RESULTS The input of multiple test images into the newly created classifier yielded an overall F-measure value of 87% (grade 1, 93%; grade 2, 67%; grade 3, 89%; grade 4C, 83%; grade 4D, 94%). These results suggest that the output of the classifier was very similar to the judgments of the clinician. CONCLUSIONS This system may be valuable for diagnostic support to provide an accurate determination of the mode of invasion.

Abstract
Objective (1) To quantify the prevalence of provider recommendation and receipt of oral cavity and pharyngeal cancer (OCPC) screening and (2) to examine the factors associated with OCPC screening recommendation and receipt among adults. Study Design Cross-sectional. Setting Rural counties in central Illinois. Methods This study among adults (N = 145) was conducted between January 1 and June 30, 2017. The outcomes of interest were provider recommendation and receipt of OCPC screening. Multivariable logistic regression models were used to examine the association between (1) sociodemographic, health care access and utilization, and OCPC risk factors and (2) provider recommendation and receipt of OCPC screening. Results The prevalence of provider recommendation and receipt of OCPC screening was 12.4% and 28.3%, respectively. Approximately 15% of current smokers, 13% of participants who consume alcohol, and 10% of participants with ≥5 lifetime sexual partners had received an OCPC screening recommendation. OCPC screening rates were 19% for current smokers, 30% for those who consume alcohol, and 32% for those with ≥5 lifetime sexual partners. In the adjusted analyses, respondents with ≥5 partners (adjusted odds ratio, 3.10 [95% CI, 1.25-7.66]) had a higher odds of receiving OCPC screening than those with <5. There were no significant associations between other OCPC risk factors and provider recommendation and receipt of OCPC screening. Conclusion OCPC screening recommendation and receipt were low; only number of lifetime sexual partners was associated with OCPC screening receipt. Our findings suggest that rural populations may be vulnerable to late-stage diagnosis of OCPC, and interventions to help improve screening rates are warranted.

Abstract
Simple Summary Radioresistance is one of the major factors contributing to radiotherapy failure in OSCC. By systematically comparing the prognostic values of all genes in TCGA-OSCC patients with and without radiotherapy, radioresistance-associated genes were identified. Higher RPL36A transcript levels were found to be associated with a poor prognosis only in OSCC patients with radiotherapy in the cohort of TCGA and another independent Taiwanese cohort. RPL36A was then shown to be involved in the regulation of DNA damage, cell cycle and apoptosis, leading to radioresistance. Thus, such integrated studies are expected to be greatly beneficial for the development of new therapeutic interventions for radioresistant OSCC in the future. Abstract Radioresistance is one of the major factors that contributes to radiotherapy failure in oral cavity squamous cell carcinoma (OSCC). By comparing the prognostic values of 20,502 genes expressed in patients in The Cancer Genome Atlas (TCGA)-OSCC cohort with (n = 162) and without radiotherapy (n = 118), herein identified 297 genes positively correlated with poor disease-free survival in OSCC patients with radiotherapy as the potential radioresistance-associated genes. Among the potential radioresistance-associated genes, 36 genes were upregulated in cancerous tissues relative to normal tissues. The bioinformatics analysis revealed that 60S ribosomal protein L36a (RPL36A) was the most frequently detected gene involved in radioresistance-associated gene-mediated biological pathways. Then, two independent cohorts (n = 162 and n = 136) were assessed to confirm that higher RPL36A transcript levels were significantly associated with a poor prognosis only in OSCC patients with radiotherapy. Mechanistically, we found that knockdown of RPL36A increased radiosensitivity via sensitizing cells to DNA damage and promoted G2/M cell cycle arrest followed by augmenting the irradiation-induced apoptosis pathway in OSCC cells. Taken together, our study supports the use of large-scale genomic data for identifying specific radioresistance-associated genes and suggests a regulatory role for RPL36A in the development of radioresistance in OSCC.

Abstract
The epithelial‑stromal interaction 1 gene (EPSTI1) is known to play multiple roles in the malignant progression of breast cancer and also in some aspects of the immune responses to the tumor. However, the relevance of the gene in the onset/progression of oral squamous cell carcinoma (OSCC) and lung squamous cell carcinoma (LSCC) is not yet known. The present study was aimed at revealing the roles of EPSTI1 in conferring malignant characteristics to OSCC and LSCC, and the underlying mechanisms. Quantitative real‑time polymerase chain reaction (PCR) and western blot analyses demonstrated significant upregulation of EPSTI1 in all four OSCC cell lines (HSC2, HSC3, HSC3‑M3 and HSC4), and significant downregulation of EPST11 in all three LSCC cell lines (LK‑2, EBC‑1 and H226) used in the present study, as compared to the expression levels in the corresponding control cell lines. Both knockdown of EPST11 in OSCC and overexpression of the gene in LSCC suppressed cell proliferation, and induced cell‑cycle arrest in the G1 phase, with upregulation of p21 and downregulation of CDK2 and cyclin D1. Furthermore, these alterations of EPST11 gene expression in the OSCC and LSCC cell lines suppressed the cell migration ability and reversed the EMT phenotype of the tumor cells. Collectively, while EPSTI1 appears to have oncogenic roles in OSCC, it appears to exert tumor‑suppressive roles in LSCC. PCR array analyses revealed some genes whose expression levels were altered along with the modified EPSTI1 expression in both the OSCC and LSCC cell lines. These findings suggest that EPSTI1 may be a therapeutic target for both OSCC and LSCC.

Abstract
Cancer was first mentioned in medicine texts by Egyptians. Ancient Indians studied oral cancer in great detail under Susruta. Cancer has continued to be a challenge to physicians from ancient times to the present. Over the years, cancer underwent a shift in management from radical surgeries toward a more preventive approach. Early diagnosis is vital in reducing cancer-associated mortality especially with oral cancer. Even though the mainstay of oral cancer diagnosis still continues to be a trained clinician and histopathologic examination of malignant tissues. Translating innovation in technological advancements in diagnostic aids for oral cancer will require both improved decision-making and a commitment toward optimizing cost, skills, turnover time between capturing data and obtaining a useful result. The present review describes the conventional to most advanced diagnostic modalities used as oral cancer diagnostics. It also includes the new technologies available and the future trends in oral cancer diagnostics.

Abstract
BACKGROUND Patients with oral squamous carcinoma (OSCC) present difficulty in precise diagnosis and poor prognosis. OBJECTIVE We aimed to identify the diagnostic and prognostic indicators in OSCC and provide basis for molecular mechanism investigation of OSCC. METHODS We collected sequencing data and clinical data from TCGA database and screened the differentially expressed mRNAs (DEmRNAs) and lncRNAs (DElncRNAs) in OSCC. Machine learning and modeling were performed to identify the optimal diagnostic markers. In order to determine lncRNAs with prognostic value, survival analysis was performed through combing the expression profiles with the clinical data. Finally, co-expressed DEmRNAs of lncRNAs were identified by interacted network construction and functional annotated by GO and KEGG analysis. RESULTS A total of 1114 (345 up- and 769 down-regulated) DEmRNAs and 156 (86 up- and 70 down-regulated) DElncRNAs were obtained in OSCC. Following the machine learning and modeling, 15 lncRNAs were identified to be the optimal diagnostic indicators of OSCC. Among them, FOXD2.AS1 was significantly associated with survival rate of patients with OSCC. In addition, Focal adhesion and ECM-receptor interaction pathways were found to be involved in OSCC. CONCLUSIONS FOXD2.AS1 might be a prognostic marker for OSCC and our study may provide more information to the further study in OSCC.

Abstract
Simple Summary Sleep disorders have been increasingly investigated in several medical illnesses as their presence may affect patients’ quality of life. However, the research examining sleep disorders in oral cancer is relatively weak. Indeed, the majority of the available studies present a cross-sectional or retrospective designs. Moreover, very few of them have evaluated quality of sleep in oral cancer survivors (OC survivors). We aimed to carry out a case-control study with the purpose to investigate sleep disorders and mood impairment in 50 OC survivors. Our research has shown that quality of sleep is significantly affected in OC survivors compared to a healthy population and that OC survivors suffers from higher levels of anxiety and depression. Our results may suggest that an appropriate assessment of quality of sleep and psychological profile should be performed in OC survivors as a prompt treatment for both sleep and mood disorders is crucial for the overall improvement of patients’ quality of life. Abstract Quality of sleep (QoS) and mood may impair oral cancer survivors’ wellbeing, however few evidences are currently available. Therefore, we aimed to assess the prevalence of sleep disorders, anxiety and depression among five-year oral cancer survivors (OC survivors). 50 OC survivors were compared with 50 healthy subjects matched for age and sex. The Pittsburgh Sleep Quality Index (PSQI), the Epworth Sleepiness Scale (ESS), the Hamilton Rating Scales for Depression and Anxiety (HAM-D, HAM-A), the Numeric Rating Scale (NRS), the Total Pain Rating Index (T-PRI) were administered. The global score of the PSQI, ESS, HAM-A, HAM-D, NRS, T-PRI, was statistically higher in the OC survivors than the controls (p-value: <0.001). QoS of OC survivors was significantly impaired, especially with regard to some PSQI sub-items as the subjective sleep quality, sleep latency and daytime dysfunction (p-value: 0.001, 0.029, 0.004). Moreover, poor QoS was negatively correlated with years of education (p-value: 0.042 *) and positively correlated with alcohol consumption (p-value: 0.049 *) and with the use of systemic medications (p-value: 0.044 *). Sleep disorders and mood disorders are common comorbidities in OC survivors; therefore, early assessment and management before, during and after treatment should be performed in order to improve the quality of life of OC survivors.

Abstract
AIM Oral cancer mostly develops from oral mucosa regions with morphological alterations transforming malignant. These visible precancerous mucosa lesions are named potentially malignant disorders (PMD). We aimed to analyze the prevalence of PMD and its risk factors for PMD in a population-based sample in Northern Germany. MATERIAL AND METHODS Data of 6078 individuals from the population-based Study of Health in Pomerania (SHIP) was used. PMD were photographically documented and periodontal health was assessed in a standardized procedure. RESULTS PMD were observed in 54 individuals (0.9%). The most prevalent PMD was homogenous leukoplakia (n = 37) followed by Lichen ruber (n = 9). Smoking (Odds Ratio (OR) 2.70; 95% confidence interval (CI): 1.24-5.87), male sex (OR 3.32; 95%-CI: 1.77-6.21), type 2 diabetes mellitus (OR 2.07; 95%-CI: 1.08-3.98) and body mass index (OR 1.09; CI 1.04-1.14) were significantly associated with PMD, with the corresponding area under the curve (AUC) being 0.696 (CI: 0.655; 0.737). CONCLUSION Our results suggest a clinically relevant prevalence of PMD in the population. We identified male sex, type 2 diabetes mellitus, current smoking, and obesity as risk factors. We recommend photographic documentation and intensified training of medical and dental staff to detect and monitor PMD.

Abstract
Oral cancer is the seventh most common malignancy worldwide, and lifestyle factors participate in its development. Rodent studies can help identify substances that contribute to its development and provide information on the early stages of carcinogenicity. The National Toxicology Program (NTP) has conducted more than 500 short-term and 2-year toxicology and carcinogenicity studies in rodents, and some of the tested compounds resulted in oral cancer. Our goal was to review the NTP carcinogenic studies to describe those chemicals that have oral carcinogenic outcome in rodents. For this project, we reviewed the results from all NTP carcinogenicity studies and a board-certified veterinary pathologist reviewed the slides from all neoplasms in the oral cavity that were considered treatment related. We have identified 26 chemicals with an adverse effect in the oral cavity. Fourteen chemicals demonstrated clear evidence of carcinogenicity in the oral cavity. We provide information on the carcinogenic findings in rodents together with a detailed description of the morphologic aspects of the oral cancers and speculate that the carcinogenic effects can be induced by different pathological modes of action. The findings reviewed here provide indicators for potential oral carcinogenesis processes in rodent models, which can be further investigated in future mechanistic studies.

The Potential of Raman Spectroscopy in the Diagnosis of Dysplastic and Malignant Oral Lesions. Cancers (Basel) 2021; 13:cancers13040619. [PMID: 33557195 PMCID: PMC7913942 DOI: 10.3390/cancers13040619] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2021] [Accepted: 02/01/2021] [Indexed: 12/12/2022] Open
Abstract
Simple Summary Raman spectroscopy, a light scattering technique that provides the biochemical fingerprint of a sample, was used on samples taken from patients with cancer and precancerous lesions. This information was then used to build a classifier to identify cancer and the precancerous phases. The ability to distinguish cancerous tissue from normal and precancerous tissue is diagnostically crucial as it can alter the patients’ prognosis and management. Moreover, as cellular changes are often present at the tumour margin, the ability to distinguish these changes from cancer can help in preserving more of the tissue and maintaining aesthetics and functionality for the patient. Abstract Early diagnosis, treatment and/or surveillance of oral premalignant lesions are important in preventing progression to oral squamous cell carcinoma (OSCC). The current gold standard is through histopathological diagnosis, which is limited by inter- and intra-observer errors and sampling errors. The objective of this work was to use Raman spectroscopy to discriminate between benign, mild, moderate and severe dysplasia and OSCC in formalin fixed paraffin preserved (FFPP) tissues. The study included 72 different pathologies from which 17 were benign lesions, 20 mildly dysplastic, 20 moderately dysplastic, 10 severely dysplastic and 5 invasive OSCC. The glass substrate and paraffin wax background were digitally removed and PLSDA with LOPO cross-validation was used to differentiate the pathologies. OSCC could be differentiated from the other pathologies with an accuracy of 70%, while the accuracy of the classifier for benign, moderate and severe dysplasia was ~60%. The accuracy of the classifier was lowest for mild dysplasia (~46%). The main discriminating features were increased nucleic acid contributions and decreased protein and lipid contributions in the epithelium and decreased collagen contributions in the connective tissue. Smoking and the presence of inflammation were found to significantly influence the Raman classification with respective accuracies of 76% and 94%.

Comparing the Incidence of Buccal Mucosa Cancer in South Asian, White, and Black Populations Residing in the United States: A Cross-Sectional Analysis. Asian Pac J Cancer Prev 2021; 22:195-199.

Abstract
Background: Recreational use of the betel nut, which is common among the South Asian population, is a known risk factor for developing Head and Neck cancer. As South Asians comprise a significant proportion of the United States population, we seek to determine if those living within the country experience a higher rate of head and neck cancers compared to other races. Methods: Data of patients diagnosed with head & neck cancers from 2010-2016 was collected from the National Cancer Database® and compared to race-matched US census data for each corresponding year to calculate incidence. Pairwise comparisons were performed between the incidence for South Asians versus Whites and South Asians versus Blacks using one sided Chi-square tests. Results: South Asians experienced a significantly higher incidence of buccal mucosa/vestibule cancers when compared to Whites or Blacks for every year between 2010-2016, but a comparatively lower incidence of larynx or oropharynx cancers. Conclusions: South Asians residing within the United States have a higher incidence of buccal mucosa/vestibule cancers, but a lower incidence of more common cancers, such as larynx or oropharynx cancer. This may suggest that the etiology behind the high buccal mucosa/vestibule cancer incidence is due to a social habit, as opposed to an inherent racial susceptibility.

Abstract
Simple Summary While previous studies have suggested that HPV-associated head and neck cancer (HNC) is mostly in the younger population, we found that in the last 40 years, the mean age at diagnosis of oropharyngeal cancer has been 60.3 years. We found that after an initially decrease leading up to the early 2000s, there has been a steady increase in age at diagnosis of oropharyngeal cancer since 2002. For non-oropharyngeal HNC, mean age at diagnosis has steadily increased throughout the last four decades. Finally, we found that age at diagnosis of HNC is higher among females in general, and lowest among blacks. Abstract The emergence of the human papillomavirus (HPV) as the primary etiology of oropharyngeal cancer has changed head and neck cancer (HNC) epidemiology. This study described change in the age at diagnosis of oropharyngeal and non-oropharyngeal HNC in the United States in the last four decades. Using a retrospective cohort analysis, the Surveillance, Epidemiology, and End Results dataset from 1975 to 2016 was queried for eligible adult cases of HNC, grouped as oropharyngeal (n = 31,702) versus non-oropharyngeal (n = 87,108). Age at diagnosis was compared by gender (female, male) using independent t-test, and by race/ethnicity (Hispanic, non-Hispanic black, non-Hispanic white, non-Hispanic other) using analysis of variance. Joinpoint regression estimated yearly increases/decreases in age of diagnosis by sex and race/ethnicity through annual percent changes (APC), which were summarized with average annual percent changes (AAPC). Mean age at diagnosis for oropharyngeal cancer was 60.3 years. While there was initially a decrease in age at diagnosis, a 0.37% annual increase occurred from 2002 to 2016 (APC = 0.37, 95% confidence interval (CI) 0.28, 0.45). For non-oropharyngeal cancer, mean age at diagnosis was 63.2 years, with a continuous increase in age at diagnosis throughout the study period (1975–2016 AAPC = 0.08, 95% CI 0.04, 0.12). Females had higher average age at diagnosis than males for both sites, while blacks (57.4 years for oropharyngeal cancer; 59.0 years for non-oropharyngeal) had the lowest age at diagnosis of all races/ethnicity. Age at diagnosis of oropharyngeal cancer has increased significantly since 2002, while non-oropharyngeal HNC has increased significantly in the last four decades.

Abstract
Despite the introduction of next-generation sequencing in the realm of DNA sequencing technology, it is not often used in the investigation of oral squamous cell carcinoma (OSCC). Oral cancer is one of the most frequently occurring malignancies in some parts of the world and has a high mortality rate. Patients with this malignancy are likely to have a poor prognosis and may suffer from severe facial deformity or mastication problems even after successful treatment. Therefore, a thorough understanding of this malignancy is essential to prevent and treat it. This review sought to highlight the contributions of next-generation sequencing (NGS) in unveiling the genetic alterations and differential expressions of miRNAs involved in OSCC progression. By applying an appropriate eligibility criterion, we selected relevant studies for review. Frequently identified mutations in genes such as TP53, NOTCH1, and PIK3CA are discussed. The findings of existing miRNAs (e.g., miR-21) as well as novel discoveries pertaining to OSCC are also covered. Lastly, we briefly mention the latest findings in targeted gene therapy and the potential use of miRNAs as biomarkers. Our goal is to encourage researchers to further adopt NGS in their studies and give an overview of the latest findings of OSCC treatment.

Abstract
Objective The aim of this study was to review the published literature and investigate whether sex determining region Y-box 2 (SOX2) is a prognostic factor in head and neck squamous cell carcinoma (HNSCC) by conduct a meta-analysis. Materials and Methods Trials were identified from the major electronic databases (MEDLINE, EMBASE, and Cochrane Library) using the key words "HNSCC" and "SOX2." The overall survival (OS), disease-specific survival (DPS), and disease-free survival (DFS) were the primary outcome measures. Results We identified 371 articles, 9 articles 11 studies with a total number of 1334 cases were eligible for inclusion of this meta-analysis. The results showed that OS (DPS) in low-expression group was higher than that in high-expression group. However, the difference between the two groups was not significant (hazard ratio [HR] = 1.30, 95% confidence interval [95% CI] = [0.88, 1.91]; P = 0.18), and there was great statistical heterogeneity (I2 = 66%, P = 0.002). After subgroup analysis, the HR for OS of the patients with reduced expression of SOX2 was 1.34 (95% CI = [1.04, 1.74], P = 0.03), and the heterogeneity became acceptable (I2 = 32%, P = 0.16). The HR for DFS of the patients with reduced expression of SOX2 was 1.39 (95% CI = [1.00, 1.93]; P = 0.05). Conclusion The findings of this meta-analysis are indicative of that high SOX2 expression is a negative prognostic factor of HNSCC and exhibit both worse OS and DFS. However, the small sample size available for this systematic review limited the power of this quantitative meta-analysis. It may therefore be too early to place complete confidence in these results.

Abstract
OBJECTIVE Identify previously unreported factors that predict the need for post-acute care after free flap reconstruction of the oral cavity. STUDY DESIGN Retrospective cohort study. SETTING Single academic medical center. METHODS A total of 134 patients with head and neck disease involving the oral cavity underwent free tissue transfer for reconstruction between August 2012 and October 2015. All patients had a tracheostomy placed at the time of surgery. Data were collected, including demographics, perioperative risk factors, and social variables. Univariate and multivariate logistic regression were used to identify risk factors for needing post-acute care. RESULTS Of 134 patients, 37 (28%) required post-acute care upon discharge, and 97 of 134 (72%) were discharged home with assistance. Multivariate logistic regression revealed that lack of family support (adjusted odds ratio [AOR], 32.12; 95% CI, 13.75-274.90; P = .002), tracheostomy tube at discharge (AOR, 13.70; 95% CI, 3.20-58.44; P < .001), government insurance (AOR, 3.85; 95% CI, 1.13-13.11; P = .031), hospital stay >10 days (AOR, 3.52; 95% CI, 1.25-9.90; P = .017), and increasing age (AOR, 1.11; 95% CI, 1.04-1.18; P = .003) were significantly associated with post-acute care need. CONCLUSION Lack of family support, tracheostomy tube at discharge, government insurance, hospital stay >10 days, and increasing age are independently associated with the need for post-acute care following free flap reconstruction of the oral cavity. Physicians, social workers, and nurse case managers are positioned to identify patients at high risk for needing post-acute care and to reduce the duration of hospitalizations.

Abstract
PURPOSE Although patients aged >70 years are subject to early oral cavity squamous cell carcinoma (E-OCSCC), evidence is currently lacking regarding the probable outcomes of definitive radiotherapy (RT) compared to surgery in this population. METHODS We recruited patients aged ≥70 years with a diagnosis of E-OCSCC from the Taiwan Cancer Registry Database. Propensity score matching was performed, and Cox proportional-hazards model curves were used to analyze all-cause mortality of patients at different age intervals undergoing different treatments. RESULTS The matching process yielded a final cohort of 604 patients in the definitive RT and surgery cohorts who were eligible for further analysis. These patients were classified as old (70-80 years) and very old (>80 years). In the multivariate Cox regression analysis, the adjusted hazard ratio (aHR) (95% confidence interval [CI]) for surgery compared with definitive RT was 0.465 (0.354-0.610, P < 0.001). The aHR (95% CI) for age >80 years compared with age 70-80 years was 2.370 (1.720, 3.265, P < 0.001). The aHR (95% CI) for T2N0M0 compared with T1N0M0 was 1.752 (1.321-2.32, P < 0.001). The aHR (95% CI) for Charlson Comorbidity Index (CCI) ≥ 2 compared with CCI = 0 was 1.264 (1.137-1.738, P = 0.011). After stratified analysis, the aHRs for surgery compared with definitive RT were 0.484 (0.352-0.665, P < 0.001) and 0.411 (0.232-0.728, P = 0.002) among old and very old patients with E-OCSCC, respectively. CONCLUSIONS Surgery may be more beneficial than definitive RT in selected elderly patients with E-OCSCC.

Abstract
This is a national scale study of spatial oral and pharynx cancer mortality and incidence clusters in the contiguous U.S.A. Spatial and space-time analyses of incidence and mortality rates of oral and pharynx cancers in the contiguous U.S.A. were done at the county resolution, using mortality data for the years 2000-2014 and incidence data for 2001-2015. The disease surveillance software SaTScan™ is used to identify significant cancer clusters that are non-random. In addition to a cluster analysis, regression analysis was used to adjust cancer incidence and mortality for several covariates or risk factors. This is the first study of the contiguous U.S.A. for oral and pharynx cancer in which mortality and incidence rates are studied together. The geographic clustering for mortality is somewhat different from the clustering for incidence. There exist several significant clusters in the contiguous U.S.A., both for oral and pharynx cancer incidence and for mortality. Some of the significant clusters persisted even after adjusting for several key risk factors. These clusters areas suggest a need for further investigation to identify some local concerns or needs to further address such cancer types in those specific sites. We identified statistically significant spatial and space-time clusters of oral and pharynx cancer for mortality and also for incidence in the contiguous US at the county resolution. The most important risk factors for oral cancer incidence are diabetes, alcohol drinking, and obesity, while the top risk factors for mortality are race, cervical cancer, diabetes, and alcohol drinking.

Abstract
Background Recent studies have shown a strong relationship between the expression of osteopontin and oral carcinogenesis. Osteopontin (OPN) has been shown to play a major role in regulating the aggressiveness of cancer cells and promote tumor growth. Odontogenic cysts are an essential aspect of oral and maxillofacial pathology. They are relatively frequent lesions with different clinical behavior. Some of them may have a proliferative pattern of growth and neoplastic nature. Evaluation of osteopontin expression with Ki-67 index may help examine clinical behavior and recurrence of oral squamous cell cancer and radicular cyst patients. Methods A total of 44 oral cavity cancer cases and 21 cysts samples were analyzed by immunohistochemical staining. Data used for analysis were derived from medical records. The following information was obtained from all patients’ medical records: survival, age, sex, lymph node status, tumor size, and location, as well as grade and histologic type of tumor. Expression status of OPN and Ki-67 was statistically assessed. Results Our data demonstrated that for summary immunoreactive scores of OPN and Ki-67 expressions in OSCC vs. RC patients statistical significance was found for both markers’ between OSCC and RC groups. Moreover, osteopontin is significantly higher expressed in larger OSCC tumors. Conclusions In conclusion, the role of OPN expression both in oral squamous cancer cells and radicular cyst and possible correlation with demographic and clinicopathological features remain undetermined in some aspects, further high-powered studies to develop a more standardized assessment of Ki-67 and osteopontin expression in OSCC and are needed.

Abstract
Taiwanin E is a bioactive compound extracted from Taiwania cryptomerioides Hayata. In this research endeavor, we studied the anti-cancer effect of Taiwanin E against arecoline and 4-nitroquinoline-1-oxide-induced oral squamous cancer cells (OSCC), and elucidated the underlying intricacies. OSCC were treated with Taiwanin E and analyzed through MTT assay, Flow cytometry, TUNEL assay, and Western blotting for their efficacy against OSCC. Interestingly, it was found that Taiwanin E significantly attenuated the cell viability of oral cancer cells (T28); however, no significant cytotoxic effects were found for normal oral cells (N28). Further, Flow cytometry analysis showed that Taiwanin E induced G1cell cycle arrest in T28 oral cancer cells and Western blot analysis suggested that Taiwanin E considerably downregulated cell cycle regulatory proteins and activated p53, p21, and p27 proteins. Further, TUNEL and Western blot studies instigated that it induced cellular apoptosis and attenuated the p-PI3K/p-Akt survival mechanism in T28 oral cancer cells seemingly through modulation of the ERK signaling cascade. Collectively, the present study highlights the prospective therapeutic efficacy of Taiwanin E against arecoline and 4-nitroquinoline-1-oxide-induced oral cancer.

Abstract
INTRODUCTION In squamous cell carcinomas of the oral cavity, factors that can predict prognosis are being studied. However, new prognostic factors are needed to provide information on the biological properties of tumors. Galectin-3 is known to be involved in many biological events such as cell adhesion and differentiation, angiogenesis, apoptosis, tumorigenesis, and metastasis. In our study, the prognostic role of galectin-3 expression in squamous cell carcinomas of the oral cavity was investigated. MATERIALS AND METHODS The study included 60 patients with a diagnosis of squamous cell carcinoma of the oral cavity. The demographic characteristics of the patients were compiled from the patient files. Galectin-3 expression was studied immunohistochemically. Cytoplasmic and nuclear expressions of galectin-3 were evaluated separately. In addition, the total expression score was calculated by multiplying the percentage and intensity scores for each cases. The critical expression score was determined according to the median value of the total scores. RESULTS Among 60 cases, 28 tumors were located on the lip, 21 on the tongue, 4 on the floor of the mouth, 3 on the orobuccal mucosa, 3 on the retromolar trigone, and 1 on the gingivobuccal junction. There was no statistically significant relationship between prognosis and nuclear or cytoplasmic galectin-3 expression. Tumor grade and invasion pattern were found to be associated with the galectin-3 total expression score. CONCLUSION Although galectin-3 total expression score was correlated with the tumor grade and invasion pattern, it is not associated with overall survival or recurrence rates. However, there is a need for a large series of cases in which methods are standardized in order to clarify the prognostic role of galectin-3 expression in oral squamous cell carcinomas.

[PMID: 32102765 DOI: 10.1016/j.oooo.2019.11.011] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2018] [Revised: 11/14/2019] [Accepted: 11/21/2019] [Indexed: 01/25/2023]
Abstract
OBJECTIVE The aim of this retrospective, single-center study was to analyze long-term results after marginal and segmental mandibulectomies in patients with oral squamous cell carcinoma (OSCC). STUDY DESIGN The study included 259 patients treated for OSCC with mandibulectomy between 1996 and 2010. Data acquisition consisted of analysis of operation reports, re-evaluation of histologic bone specimens, and collection of clinical follow-up data. RESULTS Of the included patients, 86.5% had received segmental and 13.5% marginal mandibulectomies. Patients who received segmental mandibulectomy generally displayed a higher TNM (tumor-node-metastasis) stage; 47% of patients who received segmental mandibulectomy and 14% of those receiving marginal mandibulectomy showed bone infiltration (pT4 a). Of all patients with bone infiltration, 49% showed an invasive histologic infiltration pattern, and 35% showed an erosive histologic infiltration pattern. We found healthy residual crestal bone height in 43% of all segmental mandibulectomies. Only 8% of all patients were prosthodontically rehabilitated. With regard to prognostic parameters, there was no significant difference between patients receiving marginal mandibulectomy and those receiving segmental mandibulectomy. CONCLUSIONS Because healthy residual crestal bone height was found in 43% of all patients who had received segmental mandibulectomies, it is conceivable that a significant number of patients would profit from marginal mandibulectomy, at least in cases of absent or erosive bone infiltration pattern, because the residual crestal bone is functionally stable.

Abstract
Traditional cancer models including cell lines and animal models have limited applications in both basic and clinical cancer research. Genomics-based precision oncology only help 2-20% patients with solid cancer. Functional diagnostics and patient-derived cancer models are needed for precision cancer biology. In this review, we will summarize applications of conditional cell reprogramming (CR) in cancer research and next generation living biobanks (NGLB). Together with organoids, CR has been cited in two NCI (National Cancer Institute, USA) programs (PDMR: patient-derived cancer model repository; HCMI: human cancer model initiatives. HCMI will be distributed through ATCC). Briefly, the CR method is a simple co-culture technology with a Rho kinase inhibitor, Y-27632, in combination with fibroblast feeder cells, which allows us to rapidly expand both normal and malignant epithelial cells from diverse anatomic sites and mammalian species and does not require transfection with exogenous viral or cellular genes. Establishment of CR cells from both normal and tumor tissue is highly efficient. The robust nature of the technique is exemplified by the ability to produce 2 × 106 cells in five days from a core biopsy of tumor tissue. Normal CR cell cultures retain a normal karyotype and differentiation potential and CR cells derived from tumors retain their tumorigenic phenotype. CR also allows us to enrich cancer cells from urine (for bladder cancer), blood (for prostate cancer), and pleural effusion (for non-small cell lung carcinoma). The ability to produce inexhaustible cell populations using CR technology from small biopsies and cryopreserved specimens has the potential to transform biobanking repositories (NGLB: next-generation living biobank) and current pathology practice by enabling genetic, biochemical, metabolomic, proteomic, and biological assays, including chemosensitivity testing as a functional diagnostics tool for precision cancer medicine. We discussed analyses of patient-derived matched normal and tumor models using a case with tongue squamous cell carcinoma as an example. Last, we summarized applications in cancer research, disease modeling, drug discovery, and regenerative medicine of CR-based NGLB.

Abstract
Importance Second primary malignant neoplasms (SPMNs) are the leading cause of death in survivors of head and neck squamous cell carcinoma (HNSCC). Recently, human papillomavirus (HPV) has emerged as a risk factor for oropharyngeal squamous cell carcinoma and has different prognosis from classic tobacco/alcohol-associated HNSCC. This suggests that there also may be different risks and burden of SPMNs among patients who's HNSCC were from HPV or tobacco and/or alcohol. Objective To assess SPMN risks and burden in a large US cohort of patients with a first potentially HPV-associated HNSCC vs non-HPV-associated HNSCC. Design, Setting, and Participants In this population-based retrospective cohort study, 109 512 adult patients diagnosed with HNSCC between 2000 and 2014 were identified from the Surveillance, Epidemiology, and End Results registry. Exposures HPV-relatedness based on whether patients' first HNSCC was potentially associated with HPV. Patients were grouped into 2 cohorts: potentially HPV-associated HNSCC, and non-HPV-associated HNSCC. Main Outcomes and Measures The primary outcome was incidence of SPMN (defined as the first subsequent primary cancer occurring at least 2 months after first cancer diagnosis). Excess SPMN risk was calculated using relative (standardized incidence ratios [SIRs]) and absolute (excess absolute risk [EAR] per 10 000 person-years at risk [PYR]). Results A total of 109 512 patients with HNSCC (mean [SD] age, 61.9 [12.1] years; 83 305 [76.1%] men) were identified. The overall SIR was 2.18 (95% CI, 2.14-2.22) corresponding to 160 excess cases per 10 000 PYR. The risk among patients with first potentially HPV-associated HNSCC (SIR, 1.98; EAR, 114 excess cases per 10 000 PYR) was lower than those with first non-HPV-associated HNSCC (SIR, 2.28; EAR, 188 excess cases per 10 000 PYR). Overall, the largest SIRs and EARs were observed for cancers of the head and neck, lung, and esophagus. However, the risks of SPMN were lower among potentially HPV-associated HNSCC patients. Conclusions and Relevance Patients diagnosed with HNSCC experience excess risk of SPMN, which was higher among those with non-HPV-associated HNSCC than from potentially HPV-associated HNSCC. Clinicians should implement strategies that prevent or detect SPMN early in patients with HNSCC.

Egg Consumption and Risk of Upper Aero-Digestive Tract Cancers: A Systematic Review and Meta-Analysis of Observational Studies. Adv Nutr 2019; 10:660-672.

Abstract
Limited data are available that summarize the relation between egg intake and the risk of upper aero-digestive tract (UADT) cancers. This systematic review and meta-analysis was conducted to investigate the association between egg intake and the risk of UADT cancers. Medline/PubMed, ISI web of knowledge, EMBASE, Scopus, and Google Scholar were searched using relevant keywords. Observational studies conducted on humans investigating the association between egg consumption and the risk of UADT cancers were included. Overall, 38 studies with a total of 164,241 subjects (27, 025 cases) were included. Based on 40 effect sizes from 32 case-control studies, we found a 42% increased risk of UADT cancers among those with the highest egg consumption (ranging from ≥1 meal/d to ≥1 time/mo among studies) compared to those with the lowest intake (ranging from 0-20 g/d to never consumed among studies) (overall OR: 1.42; 95% CI: 1.19, 1.68; P < 0.001). However, this association was only evident in hospital-based case-control (HCC) studies (OR = 1.50; 95% CI: 1.34, 1.68; P < 0.001 for 'oropharyngeal and laryngeal cancer' and OR: 1.27; 95% CI: 1.08, 1.50; P = 0.004 for esophageal cancer) and not in population-based case-control (PCC) studies (OR = 1.25; 95% CI: 0.59, 2.67; P = 0.56 for 'oropharyngeal and laryngeal cancer' and OR: 1.29; 95% CI: 0.92, 1.81; P = 0.13 for esophageal cancer). In addition, the association was not significant in prospective cohort studies (overall OR: 0.86; 95% CI: 0.71, 1.04; P = 0.11). Considering individual cancers, a positive association was observed between the highest egg consumption, compared with the lowest, and risk of oropharyngeal (OR: 1.88; 95% CI: 1.61, 2.20; P < 0.001), laryngeal (OR: 1.83; 95% CI: 1.45, 2.32; P < 0.001), oral & pharyngeal & laryngeal (OR: 1.37; 95% CI: 1.12, 1.67; P < 0.001), and esophageal cancers (OR: 1.28; 95% CI: 1.10,1.48; P = 0.001). We also found an inverse association between egg intake and the risk of oral cancer (OR: 0.78; 95% CI: 0.62, 0.99; P = 0.04). In conclusion, high egg consumption (ranging from ≥1 meal/d to ≥1 time/mo among studies) was associated with increased risk of UADT cancers only in HCC studies but not in PCC or prospective cohort studies. PROSPERO registration number: CRD42018102619.

Abstract
Oral squamous cell carcinoma (OSCC) is a common cancer in Taiwan and worldwide. To provide some clues for clinical management of OSCC, 72 advanced-stage OSCCs were analyzed using two microarray platforms (26 cases with Affymetrix 500 K and 46 cases with Affymetrix SNP 6.0). Genomic identification of significant targets in cancer analyses were used to identify significant copy number alterations (CNAs) using a q-value cutoff of 0.25. Among the several significant regions, 12 CNAs were common between these two platforms. Two gain regions contained the well-known oncogenes EGFR (7p11.2) and CCND1 (11q13.3) and several known cancer suppressor genes, such as FHIT (3p14.2-p12.1), FAT1 (4q35.1), CDKN2A (9p21.3), and ATM (11q22.3-q24.3), reside within the 10 deletion regions. Copy number gains of EGFR and CCND1 were further confirmed by fluorescence in situ hybridization and TaqMan CN assay, respectively, in 257 OSCC cases. Our results indicate that EGFR and CCND1 CNAs are significantly associated with clinical stage, tumor differentiation, and lymph node metastasis. Furthermore, EGFR and CCND1 CNAs have an additive effect on OSCC tumor progression. Thus, current genome-wide CNA analysis provides clues for future characterization of important oncogenes and tumor suppressor genes associated with the behaviors of the disease.

Abstract
Cytoplasmic high mobility group box 1 (HMGB1) is an autophagy regulator, and autophagy is important in the radioresistance of various solid cancers. We evaluated the degree of autophagy and cytoplasmic HMGB1 in radioresistant oral squamous cell carcinoma (SCC) by culturing the SCC15 and quasiliquid layer 1 (QLL1) SCC cell lines that originate from cancer of the oral tongue and a metastatic lymph node, respectively, and then delivered radiation to induce radioresistance to cells. We then compared the degree of autophagy between non-irradiated control and radioresistant cancer cells using a western blot assay. We also compared the total and cytoplasmic concentrations of HMGB1 between the non-irradiated control and radioresistant cancer cells by western blot assay, and extracellular concentrations of HMGB1 with an enzyme-linked immunosorbent assay (ELISA). Formation of an HMGB1-Beclin1 complex was evaluated by immunofluorescence and co-immunoprecipitation assays. Autophagy increased in the radioresistant SCC15 cells (compared with non-irradiated control SCC15 cells) but not in the radioresistant QLL1 cells. The total amount of HMGB1 expression within cells did not differ; however, the degree of cytoplasmic HMGB1 expression was higher in radioresistant SCC15 cells than in non-irradiated control SCC15 cells. The HMGB1-Beclin1 complex, which is a main regulator of autophagy, was also increased in radioresistant SCC15 cells compared with non-irradiated control SCC15 cells. Autophagy flux and cytoplasmic HMGB1-Beclin1 increased after the acquisition of radioresistance in oral SCC.

Int J Mol Med 2019; 43:1585-1596. [PMID: 30720059 PMCID: PMC6414152 DOI: 10.3892/ijmm.2019.4083] [Citation(s) in RCA: 22] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2018] [Accepted: 01/16/2019] [Indexed: 12/19/2022] Open
Abstract
MicroRNAs (miRNAs) have been shown to have a significant role in the progression of several types of cancer, including oral squamous cell carcinoma (OSCC). However, the biological function and regulatory mechanisms of miRNAs in OSCC remain to be fully elucidated. The aim of the present study was to investigate the role of miRNAs in OSCC and the relevant mechanism. Using a microarray, it was found that miRNA (miR)-199a-5p was one of the most downregulated miRNAs in OSCC tissues. A low expression of miR-199a-5p was closely associated with tumor differentiation, lymph node metastasis, tumor-node-metastasis stage, and overall survival rate. Functionally, the overexpression of miR-199a-5p suppressed cell proliferation, induced G0/G1 cell cycle arrest, and promoted the apoptosis of Tca8113 and SCC-4 cells. Subsequently, inhibitor of nuclear factor-κB (NF-κB) kinase β (IKKβ), an important regulator of NF-κB activation, was identified as a direct target of miR-199-5p. An inverse correlation was found between miR-199a-5p and IKKβ in tumor tissues. Further investigations revealed that the overexpression of IKKβ efficiently abrogated the influences caused by the overexpression of miR-199a-5p. It was also found that the miR-199a-5p-mediated anticancer effects were dependent on the inhibition of NF-κB activation. These findings indicate that miR-199a-5p functions as a tumor suppressor through regulation of the NF-κB pathway by targeting IKKβ in OSCC.

Abstract
Aims and Objectives: The aim of visual systematic screening is early identification of oral cancer (OC) precursor lesion. OC mortality improves when cancer is identified at early stages. This is important in patients whose lifestyle choices render them at higher risk of developing OC. This study described the prevalence of OC screening among smokers and nonsmokers in Kuwait and ascertained demographic predictors. Materials and Methods: This cross-sectional study utilized a self-administered online survey in English and Arabic through Survey Monkey® and disseminated using the social networking app “WhatsApp.” The survey included 21 questions on demographics, smoking status, and knowledge of OC. Screening questions were adopted from the Maryland Cancer Screening and Risk Behavior Survey. Data were analyzed using the computer software “Statistical Package for Social Sciences, SPSS version 24.0” (IBM Corp, Armonk, NY, USA). Results: The study included 404 Kuwaiti respondents, 311 (77%) nonsmokers and 93 (23%) smokers. Prevalence of OC screening was 7.2, 7.7% among nonsmokers and 5.4% in smokers. Only 36.6% were aware of OC, with more nonsmokers (38.9%) than smokers (29%). Logistic regression revealed twice more males likely to go for screening than females and with the likelihood of those being in the age group of 25–44 years four times more (P < 0.012) than other age groups. Conclusion: There was low prevalence of screening and poor awareness of OC among sampled. Increased efforts are needed by health professionals to spread awareness and improve knowledge on OC and demand the inclusion of screening during their routine and opportunistic oral examinations.

Int J Oncol 2018; 53:2423-2432. [PMID: 30320380 PMCID: PMC6203152 DOI: 10.3892/ijo.2018.4590] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2018] [Accepted: 09/19/2018] [Indexed: 12/15/2022] Open
Abstract
The expression of proinflammatory cytokines in various malignant neoplasms is widely considered to represent the host immune response to tumor development. The role of interferon (IFN)γ in head and neck squamous cell carcinoma, and its association with endoplasmic reticulum (ER) stress pathways, remains a subject of ongoing investigation. Dentin sialophosphoprotein (DSPP), which is a member of the small integrin-binding N-linked glycoproteins family, has been implicated in malignant transformation and invasion of oral squamous cell carcinoma (OSCC). Recent studies have established matrix metalloproteinase (MMP)20 as the cognate MMP partner of DSPP. The present study examined the effects of IFNγ treatment on DSPP and MMP20 expression, ER stress, the unfolded protein response (UPR), and calcium (Ca) homeostasis regulatory mechanisms in OSCC cells. The OSC2 OSCC cell line was treated with IFNγ at specific time-points. At each time-point, the mRNA expression levels of DSPP and MMP20, and those of ER-stress-, UPR- and Ca homeostasis-associated proteins [78-kDa glucose-regulated protein (GRP78), sarco/endoplasmic reticulum Ca2+-ATPase (SERCA2b), inositol 1,4,5-trisphosphate receptor (IP3r), protein kinase R-like ER kinase (PERK) and inositol-requiring enzyme 1 (IRE1)], were assessed by reverse transcription-quantitative polymerase chain reaction. The protein expression levels of B-cell lymphoma 2 (Bcl-2), Bcl-2-associated X protein (Bax), proliferating cell nuclear antigen (PCNA) and cytochrome c were analyzed by western blotting. Cell viability, apoptosis and migration were evaluated by MTT, Annexin V-fluorescein isothiocyanate flow cytometry and wound-healing assays, respectively. IFNγ treatment significantly downregulated the mRNA expression levels of the major ER stress regulator GRP78 and, to a lesser extent, the UPR-associated molecule IRE1; however, IFNγ had no significant effect on PERK. With regards to ER Ca homeostasis molecules, treatment with IFNγ downregulated the mRNA expression levels of SERCA2b and upregulated those of IP3r. Furthermore, DSPP and MMP20 mRNA expression levels were significantly reduced following IFNγ treatment. Notably, treatment with IFNγ hampered OSC2 migration, reduced cell viability and PCNA protein expression, enhanced apoptosis, downregulated Bcl-2, and upregulated Bax and cytochrome c. Overall, IFNγ inhibited OSCC cell viability and migration, and increased apoptosis, possibly by regulating ER stress and UPR mechanisms. In addition, IFNγ-induced DSPP and MMP20 downregulation may correspond with alteration in ER Ca homeostasis.

Abstract
Cancer-associated fibroblasts (CAFs) demonstrate the characteristics of myofibroblast differentiation by often expressing the ultrastructure of alpha-smooth muscle actin (αSMA). However, heterogeneity among cancer-associated fibroblasts (CAFs), with respect to αSMA expression, has been demonstrated in several clinical studies of oral cancer. Like normal stem cells, stem-like cancer cells (SLCCs) are also regulated extrinsically by its microenvironment; therefore, we postulated that the heterogeneous oral-CAFs would differently regulate oral-SLCCs. Using transcriptomics, we clearly demonstrated that the gene expression differences between oral tumor-derived CAFs were indeed the molecular basis of heterogeneity. This also grouped these CAFs in two distinct clusters, which were named as C1 and C2. Interestingly, the oral-CAFs belonging to C1 or C2 clusters showed low or high αSMA-score, respectively. Our data with tumor tissues and in vitro co-culture experiments interestingly demonstrated a negative correlation between αSMA-score and cell proliferation, whereas, the frequency of oral-SLCCs was significantly positively correlated with αSMA-score. The oral-CAF-subtype with lower score for αSMA (C1-type CAFs) was more supportive for cell proliferation but suppressive for the self-renewal growth of oral-SLCCs. Further, we found the determining role of BMP4 in C1-type CAFs-mediated suppression of self-renewal of oral-SLCCs. Overall, we have discovered an unexplored interaction between CAFs with lower-αSMA expression and SLCCs in oral tumors and provided the first evidence about the involvement of CAF-expressed BMP4 in regulation of self-renewal of oral-SLCCs.

Abstract
Synthetic corticosteroids are routinely administered during the treatment of several diseases, including malignancies. However, recent evidence suggests that corticosteroids may have tumor-promoting effects, particularly in epithelial neoplasms. Our aim was to assess the role of the recently characterized cancer-associated glucocorticoid (GC) system in the resistance to chemotherapy of oral malignant keratinocytes. Human malignant oral keratinocyte cell lines H314/H357/H400/BICR16/BICR56 were tested with: two chemotherapeutic agents, doxorubicin (DOXO) and 5-fluorouracil (5-FU), as well as hydrocortisone (HC), adrenocorticotropic hormone (ACTH), 5-pregnen-3-beta-ol-20-one-16-alfa-carbonitrile (PCN), and two glucose uptake inhibitors, Fasentin and WZB. Both DOXO and 5-FU induced apoptosis in a dose-dependent and time-dependent manner. HC administration (100 nM) reduced the effectiveness of both chemotherapeutic agents to a variable extent in all 5 oral squamous cell carcinoma cell lines. ACTH also reduced the effectiveness of DOXO on 2 cell lines tested (H357 and BICR56). The glucose uptake inhibitors Fasentin and WZB were able to partially block the increased resistance to the cytotoxic drugs induced by HC. In summary, we have demonstrated, for the first time, the importance of cortisol on oral cancer cells ability to proliferate and combat the effectiveness of chemotherapeutic agents. This effect appears to be glucose dependent.

Abstract
INTRODUCTION Oral leukoplakia is defined as a mucous membrane disorder characterized by white patches that cannot be scraped off. Leukoplakia is the most frequent, potentially premalignant oral mucosa disorder and a good candidate for chemopreventive therapies. Pioglitazone activates peroxisome proliferator-activated receptor gamma (PPARγ), which forms a complex with nuclear cofactors and regulates gene expression of a variety of cell-cycle proteins and is currently being tested preclinically and clinically in aerodigestive cancer prevention. METHODS In the present study, we hypothesized that pioglitazone would decrease proliferation of human leukoplakia cells (MSK Leuk1) and transformed bronchial epithelial cells (BEAS-2B) through regulatory changes of G1 checkpoint protein regulators, p21 and cyclin-D1. MSK Leuk1 and BEAS-2B cells were treated with pioglitazone and assayed for cell proliferation and p21 transcriptional activity. RESULTS We discovered pioglitazone significantly inhibited cell proliferation in a dose-dependent fashion. We also observed p21 protein induction after treatment with pioglitazone, which was preceded by measurable increases in p21 mRNA induction. CONCLUSIONS We conclude the PPARγ activator, pioglitazone, can activate p21, which is associated with decreased proliferation in 2 aerodigestive preneoplastic cell lines. In addition, the p21 gene may be a potential hypothesis-driven biomarker in translational studies of pioglitazone as a chemoprevention agent for aerodigestive cancer.

Abstract
Exfoliative cytology has been widely used for early diagnosis of oral squamous cell carcinoma. We have developed an oral cancer risk index using DNA index value to quantitatively assess cancer risk in patients with oral leukoplakia, but with limited success. In order to improve the performance of the risk index, we collected exfoliative cytology, histopathology, and clinical follow-up data from two independent cohorts of normal, leukoplakia and cancer subjects (training set and validation set). Peaks were defined on the basis of first derivatives with positives, and modern machine learning techniques were utilized to build statistical prediction models on the reconstructed data. Random forest was found to be the best model with high sensitivity (100%) and specificity (99.2%). Using the Peaks-Random Forest model, we constructed an index (OCRI2) as a quantitative measurement of cancer risk. Among 11 leukoplakia patients with an OCRI2 over 0.5, 4 (36.4%) developed cancer during follow-up (23 ± 20 months), whereas 3 (5.3%) of 57 leukoplakia patients with an OCRI2 less than 0.5 developed cancer (32 ± 31 months). OCRI2 is better than other methods in predicting oral squamous cell carcinoma during follow-up. In conclusion, we have developed an exfoliative cytology-based method for quantitative prediction of cancer risk in patients with oral leukoplakia.

Abstract
It has been shown that the peripheral blood mononuclear cells (PBMCs) from oral squamous cell carcinoma (OSCC) patients presented cytotoxic CD8 T cell response against Streptococcus salivarius (S. salivarius), of which the frequency was positively associated with recurrence-free survival in OSCC patients. To identify the conditions required for regulating S. salivarius-specific CD8 T cell-mediated cytotoxicity, we selectively depleted individual components of the PBMCs, and observed that the depletion of monocytes/macrophages, but not other immune cell subsets, significantly downregulated the S. salivarius-specific CD8 T cell cytotoxicity. Monocyte/macrophage alone was sufficient to reconstitute optimal granzyme B expression from S. salivarius-specific CD8 T cells. Also, both the memory and the naive CD8 T cells reacted to S. salivarius-stimulation, with the memory CD8 T cells presenting significantly higher S. salivarius-reactivity. Using M1- and M2-polarized macrophages from circulating monocytes, we found that M1-polarized macrophages, with significantly higher IL-12 expression and significantly lower IL-10 and MHC class II molecule expression, was more effective at promoting granzyme B responses in CD8 T cells, and required CD80/CD86 costimulating molecules for optimal responses. Interestingly, the tumor-associated macrophages (TAMs) from resected tumors presented characteristics of M2-polarized macrophages with high MHC class II expression and low IL-12 secretion. The frequency of tumor-infiltrating S. salivarius-specific cytotoxic CD8 T cell was inversely correlated with the level of IL-10 secretion and the MHC class II molecule expression in autologous TAMs. Together, we demonstrated that monocyte/macrophages presented essential antigen-presentation and costimulatory roles in CD8 T cell-mediated S. salivarius-specific granzyme B responses, and the polarization of macrophages could influence the potency of CD8 T cell responses.

Abstract
In view of the recently found contribution of factors associated with thrombosis and inflammation to carcinogenesis, we investigated the possible association of interleukin-6 (IL-6) with an increased risk of oral cancer. In DNA samples of 162 patients with oral squamous cell carcinoma and 156 healthy controls of comparable ethnicity, age and sex, we studied the -174 G>C polymorphism in the IL-6 gene, which affects its transcription. C allele frequencies were significantly increased in patients compared to controls, 42.6% versus 23.1% (p<0.001). The CC homozygotes had a 7-fold greater risk of developing oral cancer (odds ratio 7.39, 95% CI 2.61–20.92), while the GC heterozygotes had a 4-fold greater risk (odds ratio 3.74, 95% CI 2.29–6.11). A significant increase in C alleles was observed in patients regardless of their smoking or alcohol consumption habits, early or advanced stage of cancer, and presence or absence of a family history for cancer or thrombophilia (p<0.001; Fisher's exact test). These findings suggest that the –174 G>C polymorphism, by affecting IL-6 gene expression, is strongly associated with oral oncogenesis.
