Salivary Expression of SOX7 in Oral Squamous Cell Carcinoma: Diagnostic Accuracy Study
Oral CancerOral Squamous Cell CarcinomaThe study will include patients with oral cancer and healthy controls of both sexes. Subjects having any systemic diseases or other types of cancer will be excluded. All subjects will be selected from Oral Medicine Department, Faculty of Dentistry, Al Ahram Canadian University and Fayoum University. Informed consent will be obtained from all subjects enrolled in this study after explanation of the whole procedure.
Do Markers of Systemic Inflammatory Response and Tumor Metabolism Indicate Radioresistance in Head...
Head and Neck Squamous Cell CarcinomaThe aim of the study is to prospectively evaluate whether markers of a patient's systemic inflammatory response in addition to FDG-PET/CT metabolic parameters of the primary tumor or of nodal metastases can predict radioresistance and survival before primary radiochemotherapy in advanced head and neck cancer patients.
Prospective Study for the Prognostic and Predictive Role of Circulating Tumor Cells in Patients...
Circulating Tumor CellOropharyngeal CancerHead and neck cancers (HNSCC) are primarily squamous cell cancers represented by tumors of the upper aerodigestive tract. Locally advanced stages (stages III and IV) account for 50 to 70% of all presentations. The three main risk factors are smoking, alcohol and oropharyngeal infection with human papilloma virus (HPV). Apart from HPV status, there is no biomarker for the prognosis in HSNCC patients. Circulating Tumor Cells (CTCs) can provide "real-time" information on tumor behavior and are already used in various cancers (colon, lung). Their detection has limited sensitivity and biomarkers cannot be used for early diagnosis, but may be useful during follow-up to assess local, regional or metastatic early tumor recurrence. By using blood samples at different times (at diagnosis, after initial treatment and during follow-up), we will be able to measure the variation in quantification and establish a predictive role of these CTCs for the response to treatment. Our hypothesis is that CTCs may have a key role, in addition to clinical and radiological examination, in detecting early tumor relapse. We believe that the joint consideration of clinical parameters, treatment strategy and quantification of CTCs could optimize patient follow-up and management. The CTC extraction system, ClearCell® FX from Biolidics, is an automated microfluidic enrichment system. It has the advantage of recovering fully intact and viable CTCs from a standard blood sample. The gentle sorting principle allows to preserve cell integrity and thus the expression of surface antigens. The CTCs thus isolated can then be re-cultured or analyzed by immunostaining. This high-performance technique, in operation since December 2017 in the Biochemistry Department of Pr Claire Rodriguez-Lafrasse (HCL), has demonstrated its usefulness in lung cancer. Transcriptomic analysis of CTCs can be performed at the scale of a cell after isolation of the CTCs. CTCs can then be sequenced in RNAseq either in bulk (pool of cells) or cell by cell on our Illumina (Nextseq) sequencer, in order to define the heterogeneity of the tumor. Transcriptome analysis then provides information on the state of the cell as to its position in the epithelio-mesenchymal transition thanks to a molecular signature by phenotype. A priori-free characterization is therefore possible thanks to the RNAseq single-cell. This highly sensitive and innovative technique will allow the study of the gene expression profile of CTCs.
Prospective Observational Study to Validate Circulating HPVDNA and Prognostic Genomic Biomarkers...
Oropharyngeal Squamous Cell CarcinomaCarcinoma3 moreThe primary goal of this study is to examine whether recurrence of HPV-associated OPSCC can be predicted by two factors: 1) mutations in genes called TRAF3 and CYLD, and 2) measurements of circulating HPV DNA in blood plasma. The study will also investigate whether HPV integration is associated with TRAF3 and CYLD mutations, and whether recurrence prediction improves when looking at HPV integration along with TRAF3 and CYLD mutations.

HPV InfectionHPV Positive Oropharyngeal Squamous Cell CarcinomaThe purpose of this research is to evaluate a new test for oral HPV DNA in saliva ('oral rinse test').
Decisional Conflicts, Health-related QoL and Satisfaction With Care in High-risk cSCC in the Head-neck...
Cutaneous Squamous Cell CarcinomaCutaneous Squamous Cell Carcinoma of the Head and Neck9 morePatient reported outcomes in patients with high-risk cutaneous squamous cell carcinoma in the head-neck region are an important part of the complex care for these patients. Health-related quality of life, decision conflicts in the choice of treatment and satisfaction with care have not yet been sufficiently studied in this patient group.
Differential Mobility Spectrometry (DMS) Based Oral Tumor Analysis
Oral Squamous Cell CarcinomaThe trial is a single-center, non-randomized feasibility study aiming to evaluate the feasibility of ex-vivo tissue analysis using differential mobility spectrometry (DMS) of tissue smoke generated by the use of an electrosurgical instrument. Patients recruited in the trial receive standard-of-care oral squamous cell carcinoma tumor excision surgery.
Articulatory Adaptation Following Oral Cancer Treatment
Oral Cavity Squamous Cell CarcinomaSpeech DisordersThe goal of this longitudinal study is to learn more about the articulatory consequences of surgical oral cancer treatment. The main aims are to study the coordination and development of speech articulation of patients who will undergo surgical treatment for oral cancer longitudinally and whether individual differences in the reliance on auditory or tactile information can predict the success of speech compensatory strategies. Participants will perform multiple speech tasks while motion tracking sensors track the articulatory gestures.
A Study Using Human Papillomavirus (HPV) DNA Testing to Detect HPV-Related Oropharyngeal Cancer...
Oropharyngeal CancerHPV-Related Carcinoma1 moreThe researchers think that a blood test (NavDx®) may be able to identify cancer early by looking for circulating DNA from Human Papillomavirus/HPV. Circulating DNA are small pieces of genes that are released into the bloodstream. The purpose of this study is to find out whether using this blood test to test for HPV DNA will help detect HPV-related Oropharyngeal Cancer/OPC.
