Abstract This research aimed to investigate the prognostic factors of oral squamous cell carcinoma (OSCC), especially the role of age. A total of 33619 cases of OSCC were received from the Surveillance, Epidemiology, and End Results database during 2005–2015. Kaplan-Meier curves of 5-year overall survival rates and 5-year cancer specific survival rates were performed, and univariate and multivariate Cox regression analysis as well as competing risk model were used to help understand the relationship between various factors and mortality of OSCC. Compared to 18–39 years old group, the older age was an important predictor of worse prognosis. The multivariate analysis of overall survival (OS) were 50–59 years old (HR, 1.32; 95% CI, 1.17–1.48; p ≤ .001), 60–69 years old (HR, 1.66; 95% CI, 1.42–1.87; p ≤ .001) and 70 + years old (HR, 3.21; 95% CI, 2.86–3.62; p ≤ .001) respectively, while the specific value of competing risk model were 60–69 years old (HR, 1.21; 95% CI, 1.07–1.38; p = .002) and 70 + years old (HR, 1.85; 95% CI, 1.63–2.10; p ≤ .001). In addition, female gender, unmarried, Blacks, tumor in floor of mouth, size and higher TNM classification were also other predictors that signify significant clinically deterioration of OS / CSS. Our research revealed that age was an important factor in explaining the difference of survival in the whole process of OSCC. It’s suggested that we should pay attention to the influence of age on diagnosis, treatment and prognosis in the clinical process.

Prognostic Signature

Objectives. Oral squamous cell carcinoma (OSCC) is the most common oral cancer and has a poor prognosis. We aimed to identify new biomarkers or potential therapeutic targets for OSCC. Materials and Methods. Four pairs of tumor and adjacent normal tissues were collected from OSCC patients, and differentially expressed genes (DEGs) were screened via high-throughput RNA sequencing (RNA-seq). Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were used to analyze the DEGs. A protein-protein interaction (PPI) network was established with the Search Tool for the Retrieval of Interacting Genes/Proteins (STRING) database and Cytoscape, and two significant clusters were found. Candidate genes were screened by analyzing head and neck squamous cell carcinoma (HNSCC) data from The Cancer Genome Atlas (TCGA). A DEG-based risk model was established to predict the overall survival (OS) of OSCC patients via Kaplan-Meier analysis and the log-rank test. Furthermore, univariate Cox regression analysis was applied to assess associations between potential biomarkers and the overall survival rate. Results. Of 720 total DEGs, fifty-two DEGs in the two subclusters of the PPI network analysis were selected. A risk model was established, and five candidate genes (SPRR2E, ICOS, CTLA4, HTR1D, and CCR4) were identified as biomarkers of OS in OSCC patients. Conclusions. We successfully constructed a prognostic signature to predict prognosis and identified five candidate genes associated with the OS of OSCC patients that are potential tumor biomarkers and targets in OSCC.

Under aerobic conditions, some cancers switch to glycolysis to cover their energy requirements. Taking advantage of this process, functional imaging techniques such as PET-CT can be used to detect and assess tumorous tissues. The aim of this study was to investigate standardized uptake values and mitochondrial DNA mutations in oral squamous cell carcinoma. A cohort of 57 patients underwent 18[F]FDG-PET-CT and standardized uptake values were collected. In 15 patients, data on mitochondrial DNA mutations of the tumor were available. Kaplan–Meier curves were calculated, and correlation analyses as well as univariate Cox proportional hazard models were performed. Using ROC analysis to determine a statistical threshold for SUVmax in PET investigations, a cut-off value was determined at 9.765 MB/mL. Survival analysis for SUVmax in these groups showed a Hazard Ratio of 4 (95% CI 1.7–9) in the high SUVmax group with 5-year survival rates of 23.5% (p = 0.00042). For SUVmax and clinicopathological tumor features, significant correlations were found. A tendency towards higher mtDNA heteroplasmy levels in high SUVmax groups could be observed. We were able to confirm the prognostic value of SUVmax in OSCC, showing higher survival rates at lower SUVmax levels. Correlations between SUVmax and distinct tumor characteristics were highly significant, providing evidence that SUVmax may act as a reliable diagnostic parameter. Correlation analysis of mtDNA mutations suggests an influence on metabolic activity in OSCC.

Free Survival

Oral squamous cell carcinoma (OSCC) is a fatal disease caused by complex interactions between environmental, genomic, and epigenetic alterations. In the current study, we aimed to identify clusters of genes whose promoter methylation status correlated with various tested clinical features. Molecular datasets of genetic and methylation analysis based on whole-genome sequencing of 159 OSCC patients were obtained from the The Cancer Genome Atlas (TCGA) data portal. Genes were clustered based on their methylation status and were tested for their association with demographic, pathological, and clinical features of the patients. Overall, seven clusters of genes were revealed that showed a significant association with the overall survival/recurrence free survival of patients. The top ranked genes within cluster 4, which showed the worst prognosis, primarily acted as paraneoplastic genes, while the genes within cluster 6 primarily acted as anti-tumor genes. A significant difference was found regarding the mean age in the different clusters. No significant correlation was found between the tumor staging and the different clusters. In conclusion, our result provided a proof-of-principle for the existence of phenotypic diversity among the epigenetic clusters of OSCC and demonstrated the utility of the use epigenetics alterations in devolving new prognostic and therapeutics tools for OSCC patients.

Objective: Programmed cell death ligand 1 (PD-L1) and mammalian target of rapamycin (mTOR) are key players in host immune evasion and oncogenic activation, respectively. Evidence of the prognostic role in oral squamous cell carcinoma (OSCC) is conflicting. This study examined the associations of PD-L1 and mTOR expression with 5-year overall survival in OSCC patients. Material and Methods: The expressions of PD-L1 and mTOR proteins were immunohistochemically evaluated on tissue microarrays of 191 patients with OSCC who were treated by surgery at Songklanagarind Hospital, Thailand from 2008 to 2011. Cox regression analysis was used to determine independent prognostic factors. Results: PD-L1 expression was observed in 14.1% of cases while mTOR expression was present in 74.3% of cases. Females were more likely to have tumors with PD-L1 (p-value=0.007) and mTOR expressions (p-value=0.003) than males. In addition, lower clinical stage and well differentiated tumor are more likely to have mTOR expression (p-value= 0.038 and p-value<0.001, respectively). Cox regression analysis showed that age, tumor stage, nodal stage, combined surgical treatment with radiation or chemoradiation therapy, surgical margin status, PD-L1 expression and mTOR expression are independent prognostic factors. High PD-L1 expression (hazard ratio (HR) 3.14, 95% confidence interval (CI), 1.26–7.79) and high mTOR expression (HR 1.69, 95% CI, 1.00–2.84) are strong predictors of poor outcome. Conclusion: A proportion of OSCC expressed PD-L1 and mTOR proteins. Expression of PD-L1 and mTOR proteins are strong prognostic factors of OSCC.

AbstractOral squamous cell carcinoma (OSCC) remains one of the most challenging clinical problems in the field due to its high rate of locoregional and distant metastases. However, studies that assess the association between aspirin use and survival in patients with OSCC are limited. Moreover, patients that recruited from those studies might have tumors that arose from different anatomic regions of the head and neck, including the oral cavity, oropharynx, etc. Since tumors within these distinct anatomic regions are unique in the context of epidemiology and tumor progression, we sought to evaluate the association of aspirin use with squamous cell carcinomas located within the oral cavity only. In this 10-year cohort study, we evaluated aspirin use and survival rates in relation to clinical characteristics as well as duration of aspirin use in patients with OSCC. Our findings suggest that OSCC patients with aspirin use for more than 180 days showed improved overall and disease-specific survival rates. Aspirin also improves survival in patients across various stages of OSCC. Cox regression models indicated that aspirin use was associated with a good prognosis. In conclusion, this evidence indicates that aspirin may be potentially used as an adjuvant therapy for OSCC.

e15548 Background: Around 90% of cancer-related mortalities are caused by tumor metastasis. CTC clusters, which constitute an intermediate stage of metastasis, have not been studied extensively in head & neck cancers. The mortality rate of oral cancers remains alarmingly high, despite multimodality treatment. The aim of the study is to identify the presence of CTC clusters in patients with Oral Squamous Cell Carcinoma (OSCC) and to correlate their presence with clinical and pathological factors. Methods: Fifty patients diagnosed with histologically proven OSCC, treatment naïve, and underwent surgery at HCG Cancer Centre, Bangalore, were consented and enrolled in the study. An IRB-approved protocol allowed for the collection of 10 ml of blood from central (jugular) and peripheral veins intra-operatively, prior to tumor removal. The culturing of CTC clusters was done using ellipsoidal microwell plates maintained at hypoxic conditions, at the Institute of Bioinformatics, Bangalore. After fourteen days of culturing, the cells were fixed and stained for DAPI, Pan-CK and CD45. The CTC clusters were classified into Loose, Tight and very Tight based on the median gray values obtained from DAPI staining on ImageJ software. Clinical data was collected from patient records and subjected to analysis using Descriptive statistics. Results: From the 50 patients included in the study, 22 (44%) patients exhibited tight clusters in central blood, while only 13 (26%) patients exhibited tight clusters in peripheral blood. A higher clinical stage was observed in a greater percentage of patients with tight clusters in central blood (early: 45.5% versus late: 54.5%), but the same findings could not be inferred with pathological staging (early stage: 59.1% versus late stage: 40.1%). No significant correlation with adverse pathological features was noted. Conclusions: This observational study provides an insight into the varying biological behaviours of similarly grouped cancers, which is based on the standard TNM staging. The study forms the basis for the hypothesis of tight clusters in the central and peripheral circulation, correlating with loco-regional and distant metastasis respectively, thus leading to poorer disease-free and overall survival rates.
