Abstract
Distant metastasis is an important prognostic factor for oral squamous cell carcinoma (OSCC). It involves the direct spread of tumor cells through blood vessels or via lymph nodes; however, there are currently no well-established treatments for its prevention in patients with OSCC. To investigate the impact of metronomic neoadjuvant chemotherapy on OSCC, we conducted a retrospective analysis of the efficacy of neoadjuvant chemotherapy with S-1 alone. Fifty-four patients underwent up-front surgery, while 106 received neoadjuvant chemotherapy with S-1 alone. A serious adverse event occurred in one of patient treated with neoadjuvant chemotherapy (1%); however, all patients underwent resection. The 5-year overall survival rate was higher with S-1 than with up-front surgery (96% vs. 81%, P = 0.002). Moreover, neoadjuvant chemotherapy significantly increased the overall survival rate of patients with poorly or moderately differentiated tumors, but not those with well-differentiated tumors. By analyzing a cohort of 523 head and neck squamous cell carcinoma (HNSCC) patients in the Cancer Genome Atlas, we identified genetic variants associated with histological differentiation. The frequency of pathogenic/likely pathogenic variants or deletions in 5 genes associated with HNSCC correlated with histological differentiation, some of which indicated the activation of the Wnt/β-catenin pathway in well-differentiated HNSCC. The vessel marker CD31 was highly expressed in poorly differentiated OSCC, whereas the anti-angiogenic molecule, LCN2, which is induced by the activation of the Wnt pathway, was highly expressed in well-differentiated OSCC. The present study showed that overall survival rates were higher in patients with poorly or moderately differentiated OSCC who received metronomic neoadjuvant chemotherapy, which was attributed to a difference in angiogenesis based on the characteristic landscape of pathogenic mutations according to histological differentiation.

Abstract
OBJECTIVES To examine trends and age-period-cohort effects (APC) on oral and pharyngeal cancers incidence in Singapore between 1968 and 2017 by human papillomavirus (HPV) status. METHODS All diagnosed oral and pharyngeal cancers and population size were extracted from the Singapore Cancer Registry and the Department of Statistics Singapore, respectively. Anatomical subsites were used as a proxy for HPV infection. Prais-Winsten regression assessed trends of age-standardised incidence rate (ASIR) (per 100,000 person-years); Poisson regression assessed APC effects on HPV-related and HPV-unrelated cancers. RESULTS Over 50 years, 1,618 HPV-related and 2,977 HPV-unrelated oral and pharyngeal cancers were diagnosed, with the highest ASIR in Indians (6.93), followed by Chinese (2.81), and Malays (1.81). Overall, ASIR HPV-related cancers were stable while HPV-unrelated cancers decreased. The male-female ASIR ratio reduced from 5.82 (1968-1977) to 4.0 (2008-2017) for HPV-related cancers, and from 2.58 (1968-1977) to 1.52 (2008-2017) for HPV-unrelated cancers. HPV-unrelated ASIR in males decreased, but in females only among Indians. HPV-related ASIR decreased only among Indian females. The cohort born between 1983 and 1992 had the lowest incidence of HPV-related cancers in males but the highest in HPV-unrelated cancers. Period effect mainly contributed to HPV-related cancer among males with increased incidence after 1997. Overall, the age effect was more pronounced in males. CONCLUSIONS HPV-related cancers accounted for 1/3 of oral and pharyngeal cancers. A significant decline was observed only for HPV-unrelated cancers. The cohort effect was mainly attributed to HPV-unrelated cancer incidence, while the period effect largely contributed to HPV-related cancer incidence, but only among males.

Abstract
Introduction. The oral cavity is one of the largest reservoirs of microorganisms and many pathogenic bacteria have been shown to be associated with the aetiology of oral cancers.Gap Statement. Owing to the complexity of oral microbial communities and their unclear relationship with oral cancer, identification of specific bacteria which contribute to oral cancer is a key imperative.Aim. To compare and investigate the variations in the composition of the bacterial microbiome and its functions between patients with oral tumorous lesions and healthy subjects.Methodology. Twenty-seven samples from individuals with oral tumours (five oral benign tumours and 22 oral squamous cell carcinomas) and 15 samples from healthy subjects were collected. Genomic DNA was extracted and the V3-V5 region of the 16S rRNA gene was sequenced. Subsequently, bioinformatic assessment was conducted using QIIME2, PICRUSt and linear discriminant analysis effect size analyses (LEfSe).Results. The oral microbiota was composed mainly of the phyla Proteobacteria (31.76 %, 35.00 %), Bacteroidetes (30.13 %, 25.13 %) and Firmicutes (23.92 %, 17.07 %) in tumorous and healthy individuals, respectively. Neisseria, Prevotella, Fusobacterium, Streptococcus, Capnocytophaga, Veillonella, Haemophilus, Prevotella, Porphyromonas and Leptotrichia were the most abundant genera. Alpha diversity in the tumour group was significantly greater than that in the healthy group (P<0.05). Differential analysis of microbes between groups demonstrated a significantly higher number of Neisseria, Veillonella, Streptococcus, Leptotrichia, Lautropia, Sphingopyxis, Sphingobium, Tannerella, Actinomyces and Rothia in healthy controls compared with the tumour group. However, the genera Treponema, Micrococcus, Pseudomonas, Janthinobacterium, Parvimos, Loktanella, Staphylococcus, Acinetobacter, Catonella, Aggregatibacter and Propionibacterium were significantly higher in the tumour group. Pathways related to cancers, cell motility, environmental adaptation, metabolism and signal transduction were enhanced in the tumour group, while functions associated with immune system diseases, replication, repair and translation were significantly enhanced in the healthy group.Conclusion. Variations in the oral microbiota and its functions showed a correlation with oral tumours. The tumour group showed an increased abundance of some multi-drug-resistant and periodontitis-related pathogens. The significantly altered microbiotas may serve as potential biomarkers or inform combination therapy for oral tumours.

Abstract
Background Dietary fiber and vitamin C has been reported to play a possible role in tumorigenesis. However, few studies have estimated their association with oral cancer risk. In this project, we investigated the relationship between dietary fiber and vitamin C and oral cancer risk in adults in Southern China. Methods 382 patients newly diagnosed with oral cancer were matched to 382 hospital derived controls by frequency matching in age and sex. Pre-diagnostic consumption of dietary fiber and vitamin C intake were measured through food frequency questionnaire. Association between nutrients intake and oral cancer risk were evaluated by logistic regression. OR value and 95% confidence interval was calculated. Results Intake of dietary fiber and vitamin C was significantly lower in oral cancer patients (8.15 g/day) than in control participants (8.88 g/day). Increased dietary fiber or vitamin C intake was linked to a decreased incidence of OC after adjustment of age, marital status, residence, BMI, occupation, education, tobacco smoking, alcohol consumption and family history of cancer Ptrend< 0.001). Compared with the lowest tertile, the adjusted OR of the top tertile of dietary fiber was 0.47 (95 % CI 0.32, 0.68). While the adjusted OR of the highest tertile was 0.60 (95 % CI 0.42, 0.87) compared with the lowest tertile of vitamin C. Conclusions Dietary intake of fiber and vitamin C were lower in oral cancer patients than in control participants. Dietary fiber and vitamin C were inversely related to risk of oral cancer risk.

Abstract
Oral squamous cell carcinoma (OSCC) is the most common type of head and neck squamous cell carcinoma (HNSCC), and the effect of zymosan (ZYM), a component of the yeast cell wall, on oral cancer remains unclear. The CCK-8 proliferation assay was performed to evaluate the effect of ZYM on the proliferation of the OSCC cell lines WSU-HN4, WSU-HN6 and CAL27, and the potential mechanism was explored by quantitative real-time PCR, immunofluorescence assay and western blot. A cell adhesion assay was conducted to determine the adhesion of Candida albicans to OSCC cells, and the expression of related genes, including TLR2, MyD88, NLRP3, ASC, Caspase-1 and IL-1β, and proteins, including TLR2, MyD88, NF-κB p65, p-NF-κB p65 and E-cadherin was determined. Additionally, the pro-inflammatory cytokines including IL-6, IL-8, TNF-α and IL-1β produced by OSCC cells were detected using a chemiluminescence immunoassay (CLIA). In the current study, the CCK-8 assay showed that ZYM promoted the proliferation of WSU-HN4, WSU-HN6 and CAL27 cells via the TLR2/MyD88 pathway. The cell adhesion assay showed that the number of C. albicans cells per field significantly increased in ZYM-treated OSCC cells compared to controls. When treated with ZYM, OSCC cells secreted significantly more pro-inflammatory cytokine IL-1β, which could enhance inflammation in oral cancer microenvironment. In conclusion, ZYM from the fungal cell wall promotes the proliferation, C. albicans adhesion and IL-1β production in OSCC, as demonstrated by in vitro experiments.

Abstract
Background This study aimed to describe some of the characteristics of the inhabitants of Beijing with oral and oropharyngeal squamous cell carcinoma (OSCC) who had received treatment at the Stomatology Hospital of Peking University and to analyze the survival rate and the prognostic factors of patients following surgical treatment. Methods Data for 603 consecutive cases with primary OSCC between 2004 and 2013 were obtained from the Stomatology Hospital of Peking University. Clinical data including age, sex, living district, primary tumor site, TNM stage, history of drinking and smoking, pathological differentiation, treatment, and survival were retrospectively analyzed. Results The male:female ratio was 1.1:1. The frequency of site involvement in descending order was tongue (34.3%), gingiva (25.0%), buccal mucosa (13.8%), oral floor (9.0%), oropharynx (8.5%), lip (6.3%) and palate (3.2%). Female OSCC patients tended to be significantly older than men with OSCC (P < 0.05). The percentage of patients with TNM stage III–IV OSCC was 52.4%. The results revealed that 65.3% of male patients and only 6.3% of female patients smoked or drank. The overall 5-year survival rate was 64%. Female patients had a worse prognosis than male patients. Among the patients who received surgery, tumor size and lymph node involvement were independent prognostic factors. Smoking and drinking were not prognostic factors. Conclusion Among the Beijing inhabitants who were diagnosed with OSCC and treated in our hospital in the past 10 years, more than half were in the advanced stage, and the cancer stage was the main prognostic factor of oral cancer. Therefore, the recognition of oral cancer should be strengthened, and early detection and treatment of OSCC should be achieved to improve the survival rate.

Abstract
This survey was conducted to determine the head and neck cancer (HNC) treatment strategies followed by oncologists in Chinese hospitals. It was a questionnaire-based survey, conducted from October 2017 to January 2018 in 100 random tertiary hospitals in 21 cities of China to elicit information from oncologists on the management practices for treating HNC in China. A validated, structured questionnaire was used for formal investigation with oncologists. The questions regarding HNC types, treatment strategies used for locally advanced head and neck cancer (LA HNC) and recurrent/metastatic head and neck cancer (r/m HNC), diagnosis and prognostic factors were included. The results were presented as percentages. Among the 272 oncologists, 93.4% were from tertiary care hospitals, with 35.3% and 36.4% patients from radiotherapy (RT) and oncology department, respectively. Nasopharyngeal carcinoma was the most commonly treated type of HNC according to 65.1% oncologists. Patients aged >75 years have worse prognosis and 65% oncologists corroborated that age of the patients influences treatment decision. Most of the oncologists (77.6%) preferred chemotherapy (CT) + anti-epidermal growth factor receptor targeted therapy as the first-line therapy for r/m HNC. Approximately 95% of oncologists considered induction chemotherapy (ICT) to retain organ functions and tumor shrinkage and 43.4% preferred ICT followed by chemoradiotherapy or ICT combined with RT followed by targeted therapy for LA HNC. For the management of HNC, Chinese oncologists recommended ICT with RT and targeted therapy for LA HNC and CT regimen combined with targeted therapy for r/m HNC.
