Abstract
The substantial heterogeneity exhibited by head and neck cancer (HNC), encompassing diverse cellular origins, anatomical locations, and etiological contributors, combined with the prevalent late-stage diagnosis, poses significant challenges for clinical management. Genomic sequencing endeavors have revealed extensive alterations in key signaling pathways that regulate cellular proliferation and survival. Initiatives to engineer therapies targeting these dysregulated pathways are underway, with several candidate molecules progressing to clinical evaluation phases, including FDA approval for agents like the EGFR-targeting monoclonal antibody cetuximab for K-RAS wild-type, EGFR-mutant HNSCC treatment. Non-coding RNAs (ncRNAs), owing to their enhanced stability in biological fluids and their important roles in intracellular and intercellular signaling within HNC contexts, are now recognized as potent biomarkers for disease management, catalyzing further refined diagnostic and therapeutic strategies, edging closer to the personalized medicine desideratum. Enhanced comprehension of the genomic and immunological landscapes characteristic of HNC is anticipated to facilitate a more rigorous assessment of targeted therapies benefits and limitations, optimize their clinical deployment, and foster innovative advancements in treatment approaches. This review presents an update on the molecular mechanisms and mutational spectrum of HNC driving the oncogenesis of head and neck malignancies and explores their implications for advancing diagnostic methodologies and precision therapeutics.

Zhao Y, Yu J, Zheng C, Zhou B. Establishment of a prognostic model for hypoxia-associated genes in OPSCC and revelation of intercellular crosstalk. Front Immunol 2024; 15:1371365. [PMID: 38887298 PMCID: PMC11181350 DOI: 10.3389/fimmu.2024.1371365] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Accepted: 05/16/2024] [Indexed: 06/20/2024] Open
Abstract
Hypoxia exerts a profound influence on the tumor microenvironment and immune response, shaping treatment outcomes and prognosis. Utilizing consistency clustering, we discerned two hypoxia subtypes in OPSCC bulk sequencing data from GEO. Key modules within OPSCC were identified through weighted gene correlation network analysis (WGCNA). Core modules underwent CIBERSORT immune infiltration analysis and GSEA functional enrichment. Univariate Cox and LASSO analyses were employed to construct prognostic models for seven hypoxia-related genes. Further investigation into clinical characteristics, the immune microenvironment, and TIDE algorithm prediction for immunotherapy response was conducted in high- and low-risk groups. scRNA-seq data were visually represented through TSNE clustering, employing the scissors algorithm to map hypoxia phenotypes. Interactions among cellular subpopulations were explored using the Cellchat package, with additional assessments of metabolic and transcriptional activities. Integration with clinical data unveiled a prevalence of HPV-positive patients in the low hypoxia and low-risk groups. Immunohistochemical validation demonstrated low TDO2 expression in HPV-positive (P16-positive) patients. Our prediction suggested that HPV16 E7 promotes HIF-1α inhibition, leading to reduced glycolytic activity, ultimately contributing to better prognosis and treatment sensitivity. The scissors algorithm effectively segregated epithelial cells and fibroblasts into distinct clusters based on hypoxia characteristics. Cellular communication analysis illuminated significant crosstalk among hypoxia-associated epithelial, fibroblast, and endothelial cells, potentially fostering tumor proliferation and metastasis.

Abstract
OBJECTIVE To investigate the association of social determinants of health (SDoH) in squamous cell carcinoma of the tongue in the United States and to evaluate the real-world contribution of specific disparities. STUDY DESIGN Retrospective cohort study. SETTING United States. METHODS The Centers for Disease Control and Prevention-Social Vulnerability Index (SVI) and National Cancer Institute-Surveillance, Epidemiology, and End Results Program database were used to study 62,103 adult tongue squamous cell carcinoma patients from 1975 to 2017. Regression analysis assessed trends in months of follow-up and survival across social vulnerability and 4 subcategories of social vulnerability. RESULTS As overall SVI score increases (increased social vulnerability), there is a significant decrease in the average length of follow-up (22.95% decrease from 63.99 to 49.31 months; P < .001) across patients from the lowest and highest social vulnerability groups. As overall SVI score increases, there is a significant decrease in the average months of survival (28.00% decrease from 49.20 to 35.43 months; P < .001). There is also a significantly greater odds ratio (OR = 1.05; P < .001) of advanced cancer staging upon presentation at higher SVI scores. Patients with higher SVI scores have a lower OR (0.93; P < .001) of receiving surgery as their primary treatment when compared to patients with lower SVI scores. Patients with higher SVI scores also have a significantly greater OR (OR = 1.05; P < .001) of receiving chemotherapy as their primary treatment when compared to patients with lower SVI scores. CONCLUSION Increased social vulnerability is shown to have a detrimental impact on the treatment and prognosis of patients with squamous cell carcinoma of the tongue.

A scoping assessment of dental services at designated head and neck cancer centres in Ontario, Canada. BMC Oral Health 2024; 24:232. [PMID: 38350886 PMCID: PMC10865540 DOI: 10.1186/s12903-024-03992-6] [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: 06/13/2023] [Accepted: 02/06/2024] [Indexed: 02/15/2024] Open
Abstract
BACKGROUND Dentists serve a crucial role in managing treatment complications for patients with head and neck cancer, including post-radiation caries and oral infection. To date, dental services for head and neck cancer patients in Ontario, Canada have not been well characterized and considerable disparities in allocation, availability, and funding are thought to exist. The current study aims to describe and assess the provision of dental services for head and neck cancer patients in Ontario. METHODS A mixed methods scoping assessment was conducted. A purposive sample of dentist-in-chiefs at each of Ontario's 9 designated head and neck cancer centres (tertiary centres which meet provincially-set quality and safety standards) was invited to participate. Participants completed a 36-item online survey and 60-minute semi-structured interview which explored perceptions of dental services for head and neck cancer patients at their respective centres, including strengths, gaps, and inequities. If a centre did not have a dentist-in-chief, an alternative stakeholder who was knowledgeable on that centre's dental services participated instead. Thematic analysis of the interview data was completed using a mixed deductive-inductive approach. RESULTS Survey questionnaires were completed at 7 of 9 designated centres. A publicly funded dental clinic was present at 5 centres, but only 2 centres provided automatic dental assessment for all patients. Survey data from 2 centres were not captured due to these centres' lack of active dental services. Qualitative interviews were conducted at 9 of 9 designated centres and elicited 3 themes: (1) lack of financial resources; (2) heterogeneity in dentistry care provision; and (3) gaps in the continuity of care. Participants noted concerning under-resourcing and limitations/restrictions in funding for dental services across Ontario, resulting in worse health outcomes for vulnerable patients. Extensive advocacy efforts by champions of dental services who have sought to mitigate current disparities in dentistry care were also described. CONCLUSIONS Inequities exist in the provision of dental services for head and neck cancer patients in Ontario. Data from the current study will broaden the foundation for evidence-based decision-making on the allocation and funding of dental services by government health care agencies.

Abstract
BACKGROUND Poor oral health has been identified as a prognostic factor potentially affecting the survival of patients with head and neck squamous cell carcinoma. However, evidence to date supporting this association has emanated from studies based on single cohorts with small-to-modest sample sizes. METHODS Pooled analysis of 2449 head and neck squamous cell carcinoma participants from 4 studies of the International Head and Neck Cancer Epidemiology Consortium included data on periodontal disease, tooth brushing frequency, mouthwash use, numbers of natural teeth, and dental visits over the 10 years prior to diagnosis. Multivariable generalized linear regression models were used and adjusted for age, sex, race, geographic region, tumor site, tumor-node-metastasis stage, treatment modality, education, and smoking to estimate risk ratios (RR) of associations between measures of oral health and overall survival. RESULTS Remaining natural teeth (10-19 teeth: RR = 0.81, 95% confidence interval [CI] = 0.69 to 0.95; ≥20 teeth: RR = 0.88, 95% CI = 0.78 to 0.99) and frequent dental visits (>5 visits: RR = 0.77, 95% CI = 0.66 to 0.91) were associated with better overall survival. The inverse association with natural teeth was most pronounced among patients with hypopharyngeal and/or laryngeal, and not otherwise specified head and neck squamous cell carcinoma. The association with dental visits was most pronounced among patients with oropharyngeal head and neck squamous cell carcinoma. Patient-reported gingival bleeding, tooth brushing, and report of ever use of mouthwash were not associated with overall survival. CONCLUSIONS Good oral health as defined by maintenance of the natural dentition and frequent dental visits appears to be associated with improved overall survival among head and neck squamous cell carcinoma patients.

[PMID: 38136676 PMCID: PMC10742159 DOI: 10.3390/biom13121806] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Revised: 11/24/2023] [Accepted: 12/14/2023] [Indexed: 12/24/2023] Open
Abstract
Most current metabolomics studies of oral squamous cell carcinoma (OSCC) are mainly focused on identifying potential biomarkers for early screening and diagnosis, while few studies have investigated the metabolic profiles promoting metastasis. In this study, we aimed to explore the altered metabolic pathways associated with metastasis of OSCC. Here, we identified four OSCC cell models (CAL27, HN6, HSC-3, SAS) that possess different invasive heterogeneity via the transwell invasion assay and divided them into high-invasive (HN6, SAS) and low-invasive (CAL27, HSC-3) cells. Quantitative analysis and stable isotope tracing using [U-13C6] glucose were performed to detect the altered metabolites in high-invasive OSCC cells, low-invasive OSCC cells and normal human oral keratinocytes (HOK). The metabolic changes in the high-invasive and low-invasive cells included elevated glycolysis, increased fatty acid metabolism and an impaired TCA cycle compared with HOK. Moreover, pathway analysis demonstrated significant differences in fatty acid biosynthesis; arachidonic acid (AA) metabolism; and glycine, serine and threonine metabolism between the high-invasive and low-invasive cells. Furthermore, the high-invasive cells displayed a significant increase in the percentages of 13C-glycine, 13C-palmitate, 13C-stearic acid, 13C-oleic acid, 13C-AA and estimated FADS1/2 activities compared with the low-invasive cells. Overall, this exploratory study suggested that the metabolic differences related to the metastatic phenotypes of OSCC cells were concentrated in glycine metabolism, de novo fatty acid synthesis and polyunsaturated fatty acid (PUFA) metabolism, providing a comprehensive understanding of the metabolic alterations and a basis for studying related molecular mechanisms in metastatic OSCC cells.

Abstract
Objective.Head and neck (H&N) cancers are prevalent globally, and early and accurate detection is absolutely crucial for timely and effective treatment. However, the segmentation of H&N tumors is challenging due to the similar density of the tumors and surrounding tissues in CT images. While positron emission computed tomography (PET) images provide information about the metabolic activity of the tissue and can distinguish between lesion regions and normal tissue. But they are limited by their low spatial resolution. To fully leverage the complementary information from PET and CT images, we propose a novel and innovative multi-modal tumor segmentation method specifically designed for H&N tumor segmentation.Approach.The proposed novel and innovative multi-modal tumor segmentation network (LSAM) consists of two key learning modules, namely L2-Norm self-attention and latent space feature interaction, which exploit the high sensitivity of PET images and the anatomical information of CT images. These two advanced modules contribute to a powerful 3D segmentation network based on a U-shaped structure. The well-designed segmentation method can integrate complementary features from different modalities at multiple scales, thereby improving the feature interaction between modalities.Main results.We evaluated the proposed method on the public HECKTOR PET-CT dataset, and the experimental results demonstrate that the proposed method convincingly outperforms existing H&N tumor segmentation methods in terms of key evaluation metrics, including DSC (0.8457), Jaccard (0.7756), RVD (0.0938), and HD95 (11.75).Significance.The innovative Self-Attention mechanism based on L2-Norm offers scalability and is effective in reducing the impact of outliers on the performance of the model. And the novel method for multi-scale feature interaction based on Latent Space utilizes the learning process in the encoder phase to achieve the best complementary effects among different modalities.

Abstract
OBJECTIVE Oral hygiene has been suspected to contribute to the aetiology of head and neck cancer (HNC). Based on the meta-analysis, we evaluated the impact of oral hygiene on head and neck cancer (HNC) and its survival. MATERIALS AND METHODS Relevant case-control and cohort studies reporting survival data, oral hygiene data were searched via PubMed, Embase, Cochrane Library, and Web of Science databases. The odds ratios (ORs), hazard ratios (HRs), and 95% confidence intervals (CIs) were used. Subgroup analysis was performed. RESULTS Oral hygiene was associated with HNC. Tooth brushing ≥2 a day, dental floss use, denture wearing, caries ≥3, and dental visit ≥1 reduced the risk of oral cavity cancer while mouth wash use, missing teeth >5, gum bleeding, and periodontal disease increased the risk of oral cavity cancer. For oropharynx cancer, tooth brushing ≥2 and caries ≥3 were associated with reduced risk of it. Tooth brushing ≥2 and dental visits ≥1 decreased the risk of pharynx cancer risk and larynx cancer risk, however, missing teeth >5 increased both of them. CONCLUSION Oral hygiene was associated with HNC and its sub sites. Oral hygiene should be strengthened, a dental floss use and dentist's visits can be recommended.

Abstract
DATA SOURCES PubMed, Web of Science, the Cochrane Library and Embase were utilised as databases from inception till November 2021. STUDY SELECTION The inclusion criteria consisted of cohort and case-control studies published in the English language, which dealt with diagnosed cases of head and neck cancer reporting survival, oral hygiene and comparative data. Studies pertaining to animal experiments along with case reports, conference proceedings, reviews, letters, editorials, errata and protocols were excluded. DATA EXTRACTION AND SYNTHESIS Data such as publication year, authors' names, country, sources, study groups, age, gender, participant number, education, alcohol, tobacco, study quality, cancer site and outcomes were extracted for each included study. A modified Newcastle-Ottawa Scale was utilized to evaluate the quality of these studies. RESULTS A total of forty-four studies were included, of which forty were case-control and four were cohort in nature. These comprised of a total of 52,863 patients of which 33,000 were devoid of head and neck cancer (HNC) while, 19,863 had a confirmed diagnosis of HNC. Oral hygiene and HNC were found to be associated. CONCLUSIONS Poor oral hygiene was concluded to be associated with HNC and the subsites thereof.

A systematic review and meta-analysis. Sci Rep 2023; 13:8523. [PMID: 37237097 DOI: 10.1038/s41598-023-35503-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2023] [Accepted: 05/18/2023] [Indexed: 05/28/2023] Open
Abstract
Head and Neck Cancer (HNC) is a globally rare cancer that includes a variety of tumors affecting the upper aerodigestive tract. It presents with difficulty breathing or swallowing and is mainly treated with radiation therapy, chemotherapy, or surgery for tumors that have spread locally or throughout the body. Alternatively, exercise can be used during cancer treatment to improve function, including pain relief, increase range of motion and muscle strength, and reduce cancer-related fatigue, thereby enhancing quality of life. Although existing evidence suggests the adjunctive use of exercise in other cancer types, no previous studies have examined the effects on HNC survivors. The aim of this meta-analysis was to quantify the effect of exercise-based rehabilitation on functionality and quality of life in HNC survivors who underwent surgery and/or chemoradiotherapy. A systematic review and meta-analysis were carried out following PRISMA statement and registered in PROSPERO (CRD42023390300). The search was performed in MEDLINE (PubMED), Cochrane Library, CINAHL and Web of Science (WOS) databases from inception to 31st December 2022 using the terms "cancer", "head and neck neoplasms", "exercise", "rehabilitation", "complications", "muscle contraction", "muscle stretching exercises" combining with booleans "AND"/"OR". PEDro scale, Cochrane Risk of Bias Tool and GRADE were used to assess methodological quality, risk of bias and grade of recommendation of included studies respectively. 18 studies (n = 1322) were finally included which 1039 (78.6%) were men and 283 (21.4%) were women. In patients who underwent radio-chemotherapy, overall pain [SMD = - 0.62 [- 4.07, 2.83] CI 95%, Z = 0.35, p = 0.72] and OP [SMD = - 0.07 [- 0.62, 0.48] CI 95%, Z = 0.25, p = 0.81] were slightly reduced with exercise in comparison to controls. Besides, lower limb muscle strength [SMD = - 0.10 [- 1.52, 1.32] CI 95%, Z = 0.14, p = 0.89] and fatigue [SMD = - 0.51 [- 0.97, - 0.057] CI 95%, Z = 2.15, p < 0.01] were also improved in those who receive radio-chemoradiation. In HNC survivors treated with neck dissection surgery, exercise was superior to controls in overall pain [SMD = - 1.04 [- 3.31, 1.23] CI 95%, Z = 0.90, p = 0.37] and, in mid-term, on shoulder pain SMD = - 2.81 [- 7.06, 1.43] CI 95%, Z = 1.76, p = 0.08]. No differences in quality of life were found at any of the follow-up periods. There is evidence of fair to good methodological quality, low to moderate risk of bias, and weak recommendations supporting the use of exercise-based rehabilitation to increase functionality. However, no evidence was found in favor of the use of this modality for improving the quality of life of HNC survivors who underwent chemoradiotherapy or surgery.

Abstract
OBJECTIVE This systematic review investigated the dosimetric parameters used in preclinical studies. STUDY DESIGN Searches were performed in 3 databases (PubMed, Scopus, and Embase) and gray literature to identify studies for review. In vitro and ex vivo studies that examined the effect of radiation on human permanent teeth were included. The modified Consolidated Standards Of Reporting Trials checklist of items for reporting preclinical in vitro studies was used to assess the risk of bias. RESULTS In total, 32 studies met the inclusion criteria. The average radiation dose of in vitro studies was 53 (±22) Gy and in ex vivo studies was 69 (±1) Gy. Twenty-two studies used 5 different fractionation schemes. Twenty-two of the included studies did not report the radiotherapy modality of those reporting. Twenty studies used linear accelerators, and 7 used Cobalt-60 with the source-surface-distance of radiation ranging from 1.5 to 100 cm. Distilled water was the storage solution for the dental structure used most commonly. Biases were observed, including small sample sizes, lack of randomization, and blinding processes. CONCLUSION The dosimetric parameters used in the preclinical studies, including radiation dose, radiotherapy modality, fractionation regime, and the storage solutions used did not support the hypothesis of direct effects of radiation on the dental structure.

Impact of the absence of dental support on cancer patients during COVID-19 pandemic: a cross-sectional study. Support Care Cancer 2022; 30:9403-9410. [PMID: 36180754 PMCID: PMC9525222 DOI: 10.1007/s00520-022-07375-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2021] [Accepted: 09/19/2022] [Indexed: 11/13/2022]
Abstract
Purpose This study identifies the impact of the absence of dental support for patients with cancer whose clinical dental care was interrupted by the coronavirus disease 2019 (COVID-19) pandemic. Methods Individuals with oncologic diseases were selected from a telephone list of a Clinical Research Center (CRC) that specialized in the care of patients with cancer at the Bauru School of Dentistry, University of São Paulo (FOB/USP). The convenience sample comprised 280 patients (aged > 18 years) with a history of cancer that underwent dental treatment at the FOB/USP CRC in 2019 and did not receive care in 2020 owing to the pandemic. The participants completed a questionnaire sent via email or a text messaging application. Individuals receiving treatment or who were already treated for cancer were divided into two groups for data tabulation. Statistical analyses were performed using Fisher’s and chi-square tests. Results Of the 280 patients, 104 answered the questionnaire, and 75 (72.1%) were women. Among the women, 45 (60.0%) were receiving antineoplastic treatment, and 30 (40.0%) had already been treated. Among the men, 15 (51.7%) were receiving antineoplastic treatment, and 14 (48.3%) had already been treated. Regarding oral problems that arose during the pandemic, dental pain when eating hot or cold food or drinks (57.0%), muscle pain (53.8%), and difficulties when chewing (51.0%) were the most common reported among patients. Furthermore, most individuals reported not having received any type of remote dental follow-up, before being contacted by our team, which could contribute to reducing these oral problems. Conclusion It is impossible to say whether the absence of dental support in cancer patients during the coronavirus disease 2019 (COVID-19) pandemic had a negative impact on oral issue rates.

Relationship between oral hygiene and function and activities of daily living at discharge in convalescent patients with stroke. Jpn J Compr Rehabil Sci 2022; 13: 17-25. Objective This study was designed to examine the relationship between improvement in oral hygiene and function and activities of daily living (ADLs) at discharge in patients admitted to convalescent rehabilitation wards. Methods Eligible criteria were patients with stroke with a score of 13 or higher (i.e., severe oral problems) on the Revised Oral Assessment Guide (ROAG) at admission. Age, gender, primary diseases, rehabilitation dose, dentist visits and denture status, Eichner classification, eating status at admission and discharge, and body mass index at admission were collected. The patients were classified into two groups: those with ROAG scores of less than 9 points at discharge (good ROAG group) and those with scores of 9 points or more (poor ROAG group), and Functional Independence Measure (FIM) gain and total FIM discharge scores were compared using univariate and multivariate analyses. Results The good and poor ROAG groups comprised 126 and 366 patients, respectively. The good ROAG group had significantly higher total FIM score, FIM efficiency, and FIM gain at discharge than the poor ROAG group (112 vs. 82; P < 0.001). The ROAG scores at discharge were independently associated with FIM gain (partial regression coefficient = -9.889, 95% confidence interval = -13.499 to -6.279) and total FIM score at discharge. Conclusion Improvement in oral hygiene and function in convalescent patients with stroke was associated with ADLs at hospital discharge.

Abstract
OBJECTIVES It has been reported that in many cancer types, the evaluation of complications and side effects of treatment differs between subjective and objective evaluations. The purpose of this study is to verify whether the evaluation of postoperative oral dysfunction following oral cancer treatment was consistent subjective and objective evaluations. MATERIALS AND METHODS This cross-sectional study collected background data and evaluated the oral function (microorganisms, oral dryness, occlusal force, tongue pressure, masticatory function and eating assessment tool [EAT-10]) of 75 patients from September 2019 to December 2021. The postoperative oral dysfunction-10 (POD-10) was used for the subjective assessment of dysfunction in oral cancer patients. Also, Matsuda-Kanno classification was used for the objective assessment. The kappa coefficient between POD-10 and oral dysfunction was calculated for the degree of agreement. The relationship between oral function measurements and POD-10 was examined by multiple regression analysis. RESULTS The patients' median age was 72.0 (25-75 percentile: 64.0-78.0) and 69.3% were male. The kappa coefficients indicating the degree of agreement with POD-10 were 0.41 (P < 0.01) for occlusal force, 0.27 (P = 0.01) for masticatory function, and 0.59 (P < 0.01) for EAT-10. Multiple regression analysis showed a significant association of occlusal force (β = -0.33, P = 0.03) and EAT-10 (β = 0.80, P < 0.01) with POD-10. CONCLUSIONS For postoperative oral dysfunction type III (occlusal type), the evaluations of subjective and objective evaluations tended to be consistent. However, for type I (transport type) and II (oral hygiene type), these evaluations may be prone to overestimation or underestimation by either the medical professional or the patient.

Abstract
BACKGROUND Little is known about how factors combine to influence progression of squamous cell carcinoma of the head and neck (HNSCC). We aimed to evaluate multidimensional influences of factors associated with HNSCC stage by race. METHODS Using retrospective data, patients with similar socioeconomic status (SES), access to care (travel time/distance), and behavioral risk factors (tobacco/alcohol use and dental care) were grouped by latent class analysis. Relative frequency differences (RFD) were calculated to evaluate latent classes by stage, race, and p16 status. RESULTS We identified three latent classes. Advanced T-stage was higher for black (RFD = +20.2%; 95% CI: -4.6 to 44.9) than white patients (RFD = +10.7%; 95% CI: 2.1-19.3) in the low-SES/high-access/high-behavioral risk class and higher for both black (RFD = +29.6%; 95% CI: 4.7-54.5) and white patients (RFD = +23.9%; 95% CI: 15.2-32.6) in the low-SES/low-access/high-behavioral risk class. CONCLUSION Results suggest that SES, access to care, and behavioral risk factors combine to underly the association with advanced T-stage. Additionally, differences by race warrant further investigation.

Abstract
Objectives To assess oral hygiene indices, dental status, and oral health practices among head and neck cancer patients at King Faisal Specialist Hospital and Research Center (KFSHRC)-Jeddah. Materials and Methods The charts of 117 patients with head and neck cancer were reviewed to identify the decayed/missing/filled teeth (DMFT) index, calculus index (CI), gingival index (MGI), and oral hygiene index. The type of cancer, other systemic diseases, and sex data were extracted from the records and analyzed using SPSS statistical software for descriptive statistics, Student’s t-test, analysis of variance (ANOVA), and Spearman correlation statistical analyses. Results The total mean DMFT index was 14.33. The significant caries index (SiC) for the studied sample was 25.87. Men had a mean DMFT of 14.11 (SD 9.8). The mean DMFT index for women was 14.63 (SD 9.7). The DMFT score for patients with systemic disease was 17.47 (SD 9.9). Patients with no other diseases had a mean DMFT score of 12.82 (SD 9.3). The DMFT index was not significantly different between men and women (p = 0.925). One-way ANOVA (F = 1.729) revealed no significant difference (p = 0.110) between DMFT scores according to the location of the cancer. DMFT with systemic disease showed no significant difference (p = 0.6) in comparison to patients without systemic disease. The Spearman rho statistic revealed no correlation between the DMFT score and CI (p = 0.383). Conclusions The total DMFT score was 14.33. The total SiC was 25.87. The DMFT scores of men and women were not significantly different. Cancer location and presence or absence of systemic diseases did not affect the DMFT score. The DMFT score and CI were not correlated, but a correlation was found between the DMFT score and MGI and the oral hygiene index.

[PMID: 34838889 DOI: 10.1016/j.radonc.2021.11.011] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2021] [Revised: 11/14/2021] [Accepted: 11/17/2021] [Indexed: 12/28/2022]
Abstract
PURPOSE To analyze the impact of quality of life (QoL), nutritional and clinical indicators on overall survival in patients with head and neck squamous cell cancer (HNSCC) undergoing (chemo)radiotherapy. MATERIALS AND METHODS At the beginning, at the end of (chemo)radiotherapy and during follow-up, QoL was prospectively assessed using the EORTC-QLQ-C30 and -QLQ-H&N35 questionnaires. Data were analyzed in 58 out of 220 screened patients, who were randomized into a control and intervention group. All patients received a nutritional assessment including bioelectrical impedance analysis (BIA), laboratory testing, and a screening for malnutrition based on the questionnaires MUST, NRS-2002 and Nutriscore at baseline and at the end of therapy. The intervention consisted of an individualized nutritional counseling every 2 weeks. RESULTS Except for emotional functioning, dyspnea, financial difficulties, dental problems and weight gain, all other scales from the EORTC-QLQ-C30 and -H&N35 deteriorated during (chemo)radiotherapy. At first follow-up, patients of the control group experienced more nausea and vomiting compared to those of the intervention group (p = 0.02). After performing a multivariable model, dental problems at the end of therapy (HR: 1.03; 95% CI: 1-1.06; p = 0.03), HPV negativity (HR: 18.19, 95% CI: 1.61-204.17; p = 0.02), and baseline phase angle (HR: 0.09; 95% CI: 0.01-0.82; p = 0.03) were identified as predictors for overall survival. CONCLUSIONS Factors influencing overall survival in patients with HNSCC undergoing (chemo)radiotherapy are complex and multifactorial. We were able to identify QoL-related (dental problems), clinical (HPV status) and nutritional (phase angle) factors as negative predictors for survival. This study was registered within the German Clinical Trials Register (DRKS00016862).

Gugnacki P, Sierko E. Is There an Interplay between Oral Microbiome, Head and Neck Carcinoma and Radiation-Induced Oral Mucositis? Cancers (Basel) 2021; 13:5902. [PMID: 34885015 PMCID: PMC8656742 DOI: 10.3390/cancers13235902] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2021] [Revised: 11/22/2021] [Accepted: 11/22/2021] [Indexed: 02/07/2023] Open
Abstract
Head and neck carcinoma is one of the most common human malignancy types and it ranks as the sixth most common cancer worldwide. Nowadays, a great potential of microbiome research is observed in oncology-investigating the effect of oral microbiome in oncogenesis, occurrence of treatment side effects and response to anticancer therapies. The microbiome is a unique collection of microorganisms and their genetic material, interactions and products residing within the mucous membranes. The aim of this paper is to summarize current research on the oral microbiome and its impact on the development of head and neck cancer and radiation-induced oral mucositis. Human microbiome might determine an oncogenic effect by, among other things, inducing chronic inflammatory response, instigating cellular antiapoptotic signals, modulation of anticancer immunity or influencing xenobiotic metabolism. Influence of oral microbiome on radiation-induced oral mucositis is expressed by the production of additional inflammatory cytokines and facilitates progression and aggravation of mucositis. Exacerbated acute radiation reaction and bacterial superinfections lead to the deterioration of the patient's condition and worsening of the quality of life. Simultaneously, positive effects of probiotics on the course of radiation-induced oral mucositis have been observed. Understanding the impact on the emerging acute radiation reaction on the composition of the microflora can be helpful in developing a multifactorial model to forecast the course of radiation-induced oral mucositis. Investigating these processes will allow us to create optimized and personalized preventive measures and treatment aimed at their formation mechanism. Further studies are needed to better establish the structure of the oral microbiome as well as the dynamics of its changes before and after therapy. It will help to expand the understanding of the biological function of commensal and pathogenic oral microbiota in HNC carcinogenesis and the development of radiation-induced oral mucositis.

Abstract
There is increasing evidence showing positive association between changes in oral microbiome and the occurrence of oral squamous cell carcinoma (OSCC). Alcohol- and nicotine-related products can induce microbial changes but are still unknown if these changes are related to cancerous lesion sites. In an attempt to understand how these changes can influence the OSCC development and maintenance, the aim of this study was to investigate the oral microbiome linked with OSCC as well as to identify functional signatures and associate them with healthy or precancerous and cancerous sites. Our group used data of oral microbiomes available in public repositories. The analysis included data of oral microbiomes from electronic cigarette users, alcohol consumers, and precancerous and OSCC samples. An R-based pipeline was used for taxonomic and functional prediction analysis. The Streptococcus spp. genus was the main class identified in the healthy group. Haemophilus spp. predominated in precancerous lesions. OSCC samples revealed a higher relative abundance compared with the other groups, represented by an increased proportion of Fusobacterium spp., Prevotella spp., Haemophilus spp., and Campylobacter spp. Venn diagram analysis showed 52 genera exclusive of OSCC samples. Both precancerous and OSCC samples seemed to present a specific associated functional pattern. They were menaquinone-dependent protoporphyrinogen oxidase pattern enhanced in the former and both 3',5'-cyclic-nucleotide phosphodiesterase (purine metabolism) and iron(III) transport system ATP-binding protein enhanced in the latter. We conclude that although precancerous and OSCC samples present some differences on microbial profile, both microbiomes act as "iron chelators-like" potentially contributing to tumor growth.

Abstract
OBJECTIVES Several factors have been associated with hyperglycemia after kidney transplantation (KTx), including systemic inflammation. This study aimed to investigate the relationship between periodontal status and hyperglycemia in KTx patients. MATERIALS AND METHODS Forty-four KTx patients were included in this cross-sectional study. Periodontitis severity was categorized into stage I to IV. Fasting blood glucose (FBG) was measured, and hyperglycemia was analyzed at different FBG cutoff points (100 mg/dL, 110 mg/dL, 120 mg/dL, 126 mg/dL, 140 mg/dL). Age, history of smoking, prior type 2 diabetes (T2D), and prior cardiovascular disease (CVD) were considered cofounders. Multivariable logistic regression modelling was performed with periodontitis as the exposure and hyperglycemia as the outcome. Pathway analysis was performed with FBG as a continuous outcome. RESULTS Periodontitis had increased odds of hyperglycemia from 120 mg/dL FBG cutoff, even after adjustment. In addition, periodontitis severity was positively associated with FBG level (β = 0.323, SE = 0.127, P = 0.011). CONCLUSION The findings suggest that periodontitis may be related to increase of hyperglycemia and FBG levels in KTx patients. CLINICAL RELEVANCE Periodontitis severity and cardiovascular disease were positively associated with FBG levels in KTx patients. Clinicians and patients should be aware of the potential benefit of periodontal care for better glycemic control management.

Abstract
OBJECTIVE Results of epidemiological studies evaluating the association between toothbrushing and gastric and upper aerodigestive tract (UADT) cancer risk showed inconsistent results. The purpose of this study was to evaluate the association between toothbrushing and gastric and UADT cancer risk and quantify the dose-response association between them. METHODS We searched the PubMed, EMBASE and Cochrane Library databases to identify relevant studies on toothbrushing and gastric and UADT cancer risk. Statistical analyses were performed using STATA 12.0 software. RESULTS A total of 30 studies of involving 1 194 017 participants met eligibility criteria and were included in the meta-analysis. Meta-analysis using a random-effect model showed that the high frequency of toothbrushing was associated with significantly reduced risk of gastric and UADT cancers (OR: 0.55, 95% CI 0.46-0.64, P < .05). Our dose-response analysis presented that every increased toothbrushing per day might reduce oral cavity cancer risk by 6%, pharyngeal cancer risk by 11%, laryngeal cancer risk by 3%, oesophageal cancer risk by 6% and gastric cancer risk by 4%. CONCLUSIONS This meta-analysis suggested the negative relationship between frequency of toothbrushing and risk of gastric and UADT cancers. Toothbrushing may be a protective factor for gastric and UADT cancers. However, this association must be further validated through large prospective studies.

Abstract
OBJECTIVE/HYPOTHESIS The objective of this study was to perform a systematic review and meta-analysis to determine the impact of dental care on head and neck (H&N) cancer survival. METHODS A comprehensive literature search was performed using PubMed, MEDLINE, and CINAHL to find all relevant studies from the date of inception to March 2020. Systematic review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and meta-analysis was performed using the random effects logistic regression model. Primary outcomes of interest were 5-year survival and hazard ratios comparing survival between dental care subgroups. RESULTS H&N cancer survival rates strongly correlate with dental care adherence. Patients with good dental care had significantly better survival than patients with poor dental care (HR = 0.67, 95% CI: 0.55-0.83), with similar improved survival among patients with moderate versus poor dental care (HR = 0.67, 95% CI: 0.57-0.80). In addition, patients with good dental care had significantly decreased mortality than those with moderate dental care (HR = 0.81, 95% CI: 0.69-0.96), indicating an exposure-response gradient. CONCLUSIONS For patients with H&N cancer, survival is significantly higher in those who receive recommended dental care compared with those who do not. LEVEL OF EVIDENCE N/A Laryngoscope, 2021.

Abstract
This study explored the association between oral microbes and head and neck cancer (HNC) as well as symptoms related to patients with HNC before surgical treatment. Fifty-six patients with HNC and 64 matched healthy controls were recruited from West China hospital in Southwest China. The demographic, clinical, and symptom data were collected. Salivary samples were collected to determine the microbial characteristics using 16S rRNA gene sequencing. Patients with HNC presented increased Capnocytophaga abundances. The oral microbial markers as Capnocytophaga (area under the curve=0.81) achieved a high classification power between the HNC patients and healthy controls. Moreover, using Capnocytophaga in conjunction with symptom of voice/speech difficulty achieved an overall predicting accuracy of 92.5% comparing with using Capnocytophaga alone (79.2% accuracy) in distinguishing the HNC patients from healthy controls. Salivary microbial profiles and HNC symptoms may be potential biomarkers for HNC screening.

Validation of genome-wide association study-identified single nucleotide polymorphisms in a case-control study of pancreatic cancer from Taiwan. J Biomed Sci 2020; 27:69. [PMID: 32456644 PMCID: PMC7251895 DOI: 10.1186/s12929-020-00664-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2019] [Accepted: 05/22/2020] [Indexed: 02/07/2023] Open
Abstract
Background Due to differences in genetic background, it is unclear whether the genetic loci identified by the previous genome-wide association studies (GWAS) of pancreatic cancer also play significant roles in the development of pancreatic cancer among the Taiwanese population. Methods This study aimed to validate the 25 pancreatic cancer GWAS-identified single nucleotide polymorphisms (SNPs) in a case-control study (278 cases and 658 controls) of pancreatic cancer conducted in Taiwan. Statistical analyses were conducted to determine the associations between the GWAS-identified SNPs and pancreatic cancer risk. Gene-environment interaction analysis was conducted to evaluate the interactions between SNPs and environmental factors on pancreatic cancer risk. Results Among the 25 GWAS-identified SNPs, 7 (rs2816938 (~ 11 kb upstream of NR5A2), rs10094872 (~ 28 kb upstream of MYC), rs9581943 (200 bp upstream of PDX1) and 4 chromosome 13q22.1 SNPs: rs4885093, rs9573163, rs9543325, rs9573166) showed a statistically significant association with pancreatic cancer risk in the current study. Additional analyses showed two significant gene-environment interactions (between poor oral hygiene and NR5A2 rs2816938 and between obesity and PDX1 rs9581943) on the risk of pancreatic cancer. Conclusions The current study confirmed the associations between 7 of the 25 GWAS-identified SNPs and pancreatic risk among the Taiwanese population. Furthermore, pancreatic cancer was jointly influenced by lifestyle and medical factors, genetic polymorphisms, and gene-environment interaction. Additional GWAS is needed to determine the genetic polymorphisms that are more relevant to the pancreatic cancer cases occurring in Taiwan.

Silverman DA, Lin C, Tamaki A, Puram SV, Carrau RL, Seim NB, Eskander A, Rocco JW, Old MO, Kang SY. Respiratory and pulmonary complications in head and neck cancer patients: Evidence-based review for the COVID-19 era. Head Neck 2020; 42:1218-1226. [PMID: 32343013 PMCID: PMC7267530 DOI: 10.1002/hed.26217] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2020] [Accepted: 04/14/2020] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Pulmonary complications and infections frequently affect patients with head and neck squamous cell carcinoma (HNSCC). Common characteristics can predispose these patients to the development of severe respiratory illness, which may be particularly relevant during the 2019 coronavirus disease (COVID-19) pandemic. METHODS A scoping review was performed to assess the impact of pulmonary comorbidities and adverse respiratory outcomes in HNSCC patients. RESULTS Advanced age, history of tobacco and alcohol abuse, and cardiopulmonary comorbidities are significant risk factors for the development of adverse respiratory outcomes. Treatment toxicities from radiation or chemoradiation therapy significantly increase these risks. CONCLUSION Respiratory complications are a frequent cause of morbidity and mortality among HNSCC patients, and the COVID-19 pandemic may disproportionately affect this population. Interventions designed to decrease smoking and alcohol use, improve oral hygiene, and aggressively manage medical comorbidities are important to the long-term management and health of these patients.

Nuclear Magnetic Resonance Metabolomics Biomarkers for Identifying High Risk Patients with Extranodal Extension in Oral Squamous Cell Carcinoma. J Clin Med 2020; 9:jcm9040951. [PMID: 32235493 PMCID: PMC7230778 DOI: 10.3390/jcm9040951] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2020] [Revised: 03/24/2020] [Accepted: 03/25/2020] [Indexed: 12/16/2022] Open
Abstract
Extranodal extension (ENE) is an independent adverse prognostic factor in oral squamous cell carcinoma (OSCC), and is difficult to identify preoperatively. We aimed to discover biomarkers for high risk patients with ENE. Tandem tissue, plasma, and urine samples of 110 patients with OSCC were investigated through 600-MHz nuclear magnetic resonance (NMR) metabolomics analysis. We found that the levels of creatine, creatine phosphate, glycine, and tyramine in plasma significantly decreased in stage IV ENE positive OSCC compared with stage IV ENE negative OSCC. To understand the underlying mechanism behind the alteration of plasma metabolites, our tissue analysis revealed that the carnitine level significantly increased in tumors but significantly decreased in the adjacent normal tissue in advanced stage OSCC, in addition to decreased levels of alanine and pyruvate in tumor tissues. The global metabolomics analysis on tumor tissues also showed that stage IV tumors with an ENE positive status demonstrated higher levels of aspartate, butyrate, carnitine, glutamate, glutathione, glycine, glycolate, guanosine, and sucrose but lower levels of alanine, choline, glucose, isoleucine, lactate, leucine, myo-inositol, O-acetylcholine, oxypurinol, phenylalanine, pyruvate, succinate, tyrosine, valine, and xanthine than tumors with an ENE negative status. We concluded that metabolomics alterations in tumor tissues correspond to an increase in the tumor stage and are detectable in plasma samples. Metabolomic alterations of OSCC can serve as potential diagnostic markers and predictors of ENE in patients with stage IV OSCC.

Oral hygiene and the overall survival of head and neck cancer patients. Cancer Med 2019; 8:1854-1864.

Abstract
Poor oral hygiene is an established risk factor of head and neck cancer (HNC); however, its role in the survival of HNC patients is unclear. This study evaluated the association between oral hygiene habits, including regular dental visits, frequency of tooth brushing, and use of dental floss, and the overall survival (OS) of HNC patients using interview data collected from 740 HNC patients. In addition, the interactions between oral hygiene and the polymorphisms of TLR2 and TLR4 on the OS of HNC patients were assessed. The analysis indicated that poor oral hygiene was significantly associated with poorer OS of HNC patients (hazard ratio (HR) = 1.38, 95% confidence interval (CI): 1.03‐1.86). This association was modified by a single nucleotide polymorphism, rs11536889, of TLR4. A significant association between poor oral hygiene and worse survival of HNC was observed among those with the CG or CC genotype (HR = 2.32, 95% CI: 1.41‐3.82) but not among those with the GG genotype (HR = 0.95, 95% CI: 0.65‐1.40). Our results suggested that poor oral hygiene is not only a risk factor but may also be a prognostic factor of HNC. Poor oral hygiene was associated with a worse survival of head and neck cancer. TLR4 affected the survival of head and neck cancer due to poor oral hygiene. Poor oral hygiene is both a risk and a prognostic factor of head and neck cancer
