Oral Squamous Cell Carcinoma

Background: Head and neck cancers (HNCs) account for about 5% of all cancers worldwide. They grow in the mouth, throat, nasal cavity, or salivary glands. Prostate cancer is the most common cancer in men in the United States. Survival rates for these cancers are lower than 50% if they spread to other parts of the body or return after treatment. Better treatments are needed. Objective: To test a new drug (SX-682), combined with an approved drug (docetaxel, or DTX), in people with HNCs or prostate cancer. Eligibility People aged 18 years and older with an HNC or prostate cancer that has returned after treatment or has spread. Design: Participants will be screened. They will have blood tests, imaging scans, and a test of their heart function. A tissue sample (biopsy) of the tumor may be taken. Participants will take the study drugs in 3-week cycles. SX-682 is a tablet taken by mouth twice a day from Days 1 to 11 of each cycle. Participants will get a supply of the drug to take home. DTX is given on Day 8 of each cycle through a tube attached to a needle inserted into a vein in the arm. Participants will come to the clinic on Days 1 and 8 of every cycle. They will take both drugs for up to 6 cycles. Participants will have follow-up visits 1 week and 1 month after they finish taking the drugs. Follow-ups will continue every 3 months for 2 years. Then they will have phone or email check-ins twice a year until 5 years have passed.

This is an exploratory qualitative study among People Living With HIV (PLWH) of diverse racial/ethnic and sexual and gender minority (SGM) identities to explore individual, interpersonal, and structural oral health equity factors that serve as barriers or facilitators of accessing oral health care, knowledge and perceptions of human papillomavirus (HPV) vaccination and Oral squamous cell carcinoma (OSCC) /Oropharyngeal squamous cell carcinoma (OPSCC), and to collect recommendations on how to increase access to oral health care and engage PLWH in OSCC/OPSCC prevention.

This clinical study aims to evaluate the effectiveness of patient-specific 3D-printed titanium facial implants in the reconstruction and aesthetic correction of facial defects. The study will include patients presenting with congenital, traumatic, or post-surgical facial deformities requiring reconstructive intervention. Eligible participants will undergo preoperative clinical assessment and radiological imaging to design customized implants using computer-aided design (CAD) and 3D printing technology. The implants will be fabricated from medical-grade titanium and surgically placed according to standardized maxillofacial reconstructive protocols. Postoperative follow-up will assess functional outcomes, implant stability, complication rates, and aesthetic improvement over a defined observation period. Outcome evaluation will include clinical examination and patient-reported satisfaction measures. The objective of this study is to determine whether patient-specific 3D-printed titanium implants provide reliable functional restoration and improved aesthetic outcomes in facial reconstruction compared to conventional reconstructive techniques.

The goal of this phase II single arm clinical study is to evaluate the effect of antibiotics (metronidazole) and oral chlorhexidine (CHX) in reducing the bacteria load within tumors of patients undergoing surgery for oral cancer.

Head and neck squamous cell carcinoma (HNSCC) are malignant tumors originating from the epithelial mucosa of the upper aerodigestive tract. The oral cavity is the most frequent location of HNSCC (oral squamous cell carcinoma: OSCC). Tobacco use and alcohol consumption are the greatest risk factors. The Hauts de France region has one of the highest incidence rates of OSCC. The overall survival of patients with OSCC remains low, with a 5-year overall survival rate of around 60%. In addition to the oncological prognosis, OSCCs and their treatment have a significant impact on the quality of life of patients. An early diagnosis of OSCC is recommended, but it remains difficult. It can be for example challenging to diagnose OSCC in a context of oral premalignant lesions. Identifying objective biomarkers of malignancy would be an advantage and would allow better progress in the field of precision medicine and surgery for these tumors. The investigators propose to establish the diagnostic use of an optimized DNA methylation profile detected in the saliva of OSCC patients by comparing these epigenetic marks before and after tumor resection. The investigators will construct a consolidated signature of 4 genes whose DNA is subject to methylation and gene expression is restricted to cancer cells, by crossing TCGA analysis with single-cell analysis (single-cell RNA sequencing). The investigators propose to analyse DNA methylation of the corresponding genes in the saliva of n=30 OSCC patients recruited for primary surgical resection in the Department of Maxillofacial Surgery vs controls. In addition, the investigators will examine the methylation profiles before / after complete excisional surgery of OSCC. This pilot study will aim to validate the analysis of DNA methylation markers in saliva of OSCC, with the aim of improving the diagnostic precision of OSCC and, secondly, to compare these markers before and after treatment by primary surgery.

The primary goal of this study is to see if photodynamic therapy (PDT) is effective for treatment of lesions in the oral cavity which have high risk of becoming oral cancer. PDT treatment uses a drug, called a photosensitizer, which makes the diseased cells become light-sensitive such that they are destroyed when laser light is delivered to the target lesion. In this study a new handheld device, called SITOS (a "Screen, Image and Treat Optical System), is used. The ability of this device to simultaneously visualize the inside of the mouth and deliver laser light to the target site will be evaluated. The main questions this study seeks to answer are: * Can this treatment completely cure oral potentially malignant lesions (OPML) without need for surgery? * Do lesions recur after PDT treatment? * Is the SITOS device easy to use for the doctor and comfortable for the patient, both as an oral imaging device and as a treatment device?

Oral diseases are currently diagnosed by means of clinical examination and supported by surgical biopsy procedures. In particular, daily oral medicine practice is lacking the use of a routine diagnostic support to the visualization of anatomical structures located beyond the mucosal surface. Considering the growing interest in minimally invasive diagnosis, the possibility of having an imaging technique dedicated to the investigation of oral soft tissues and their alterations may be instrumental to support the clinical diagnosis. Therefore, attempts to introduce conventional ultrasonography (US) to the diagnostic work-up of pathological conditions of the head and neck have been done, exploiting the unique features of this technique in terms of limited invasive- ness, repeatability, and cost efficiency. In the literature, both extraoral and intraoral applications of US have been reported. Extraoral applications mainly focus on the characterization of oral and maxillofacial swellings of various origin, while intraoral applications mostly involve the study of malignant lesions in terms of tumor thickness and depth of invasion. The aim of the present protocol is to evaluate the role of intraoral ultra-high frequency ultrasonography in the study of oral mucosal lesions.

The purpose of this study to find out whether sacituzumab govitecan in combination with cetuximab is an effective and safe treatment approach for people with recurrent and/or metastatic head and neck squamous cell cancer (HNSCC).

The diagnostic and pre-therapeutic assessment of squamous cell carcinomas requires a neck and chest CT scan and a neck and facial MRI, which is the most effective examination, to establish the TNM stage of the tumor. However, obtaining this complete assessment can delay treatment. Confirmation of the non-inferiority of 40keV dual-energy CT in BOLT compared to MRI would spare the patient an additional MRI examination, speed up the pre-treatment assessment, reduce the loss of opportunity due to delayed treatment, and free up MRI imaging slots, which are still insufficient in the region.

This clinical trial aims to assess the efficacy of Optical Coherence Tomography (OCT) in the early diagnosis of oral cancer. It focuses on Oral Potentially Malignant Disorders (OPMDs) as precursors to Oral Squamous Cell Carcinoma (OSCC). Despite the availability of oral screening, diagnostic delays persist, underscoring the importance of exploring non-invasive methodologies. The OCT technology provides cross-sectional analysis of biological tissues, enabling a detailed evaluation of ultrastructural oral mucosal features. The trial aims to compare OCT preliminary evaluation with traditional histology, considered the gold standard in oral lesion diagnosing. It seeks to create a database of pathological OCT data, facilitating the non invasive identification of carcinogenic processes. The goal is to develop a diagnostic algorithm based on OCT, enhancing its ability to detect characteristic patterns such as the keratinized layer, squamous epithelium, basement membrane, and lamina propria in oral tissues affected by OPMDs and OSCC. Furthermore, the trial aims to implement Artificial Intelligence (AI) in OCT image analysis. The use of machine learning algorithms could contribute to a faster and more accurate assessment of images, aiding in early diagnosis. The trial aims to standardize the comparison between in vivo OCT images and histological analysis, adopting a site-specific approach in biopsies to improve correspondence between data collected by both methods. In summary, the trial not only evaluates OCT as a diagnostic tool but also aims to integrate AI to develop a standardized approach that enhances the accuracy of oral cancer diagnosis, providing a significant contribution to clinical practice.

To evaluate the prognostic efficacy of neoadjuvant immunochemotherapy with tislelizumab, albumin paclitaxel and cisplatin followed by radical surgery and adjuvant therapy compared with standard therapy for patients with locally advanced and resectable oral squamous cell carcinoma.

A total of at least 1,000 participants with suspicion of cancer including at least 107 subjects who will be diagnosed with OSCC or OPSCC will be enrolled from either primary or secondary care centers in the U.S. Clinicians will use Viome collection kits to collect saliva samples from eligible patients.

To evaluate the design, safety and efficacy of OralViome Cancer Testing system in the early detection of Oral and Throat Cancers using saliva metatranscriptomic analysis. This study will recruit only at existing clinical sites and will NOT use any additional clinical sites.

Evaluation of the Tolerance and Benefits of Mandibular Advanced Device (MAD) for Snoring and Sleep Apnea in Patients with Oropharyngeal Cancer (OPC): Mixed Design Study.

Early detection - possibly at its pre-malignant stages (Oral Potentially Malignant Disorders, OPMD) - with periodic surveillance is thus fundamental for limiting disease burden, hopefully reducing the incidence of advanced stages OSCC and increasing survival. Narrow Band Imaging (NBI) has proved itself as promising tool for helping clinician both for diagnosis and therapy. Yet, there is no definitive scientific evidence that NBI is superior to common oral examination with white light (WLOE) for diagnosing OSCC/OPMD. We thus propose a randomised clinical trial understand its role in this field.

The purpose of this study is to investigate the survival benefit of neoadjuvant anti-PD-1 immunotherapy plus TP chemotherapy compared with TP chemotherapy or up-front surgery in resectable locally advanced oral squamous cell carcinoma.

The study is being conducted to evaluate the efficacy and safety of sintilimab in combination with reduction of cycles of chemotherapy (carboplatin and nab-paclitaxel) in patients with oral cavity or oropharyngeal squamous cell carcinoma who are about to undergo surgery. Data obtained in this trial will provide valuable information for planning further prospective clinical trials of anti-PD-1 and other immunotherapies in oral cavity or oropharyngeal squamous cell carcinoma.

To compare the pathological efficacy of neoadjuvant Toripalimab and Albumin paclitaxel /Cisplatin (TTP) with Docetaxel/ Cisplatin/ 5-flurouracil (TPF) for patients with locally advanced resectable oral squamous cell carcinoma (OSCC), and to determine the safety of neoadjuvant TTP. In order to explore a better protocol of neoadjuvant therapy to improve the efficacy in patients with locally advanced OSCC.

To evaluate the efficacy of neoadjuvant anti-PD-1 plus anti-VEGFR therapy for patients with locally advanced and resectable oral squamous cell carcinoma, and the CPS\>10 in the biopsy samples.

TPF is still recommended as the preferred induction chemotherapy regimen for nonsurgical treatment of patients with LA HNSCC. Based on the KEYNOTE-048 study, all major guidelines recommend PD-1 monotherapy or PD-1 combined with chemotherapy as the new first-line standard treatment for patients with advanced HNSCC. The immunotherapy in operable LA HNSCC was also explored as neoadjuvant therapy due to the excellent data in advanced HNSCC. These explorations have also achieved good results. Therefore, this study aims to explore the pathological remission rate, the long-term benefit and safety of Tislelizumab combined with albumin paclitaxel, cisplatin and fluorouracil for locally advanced oral squamous cell carcinoma.

Research shows that most oral cancer patients are already locally advanced when first diagnosed. Even after surgery and radiation, nearly half of patients develop recurrence or metastasis. Even in patients who survive, there is a serious decline in quality of life due to the after-effects of surgery and radiation. Many patients therefore refuse surgery and lose the treatment opportunity. Many studies at home and abroad have found that preoperative induction chemotherapy for locally advanced tumors can reduce tumor load, reduce tumor scope, eliminate distant micro metastases, reduce the risk of recurrence and metastasis, and improve organ preservation rate. It has been confirmed in many clinical studies and our clinical practice of oral cancer MDT(Multi-Disciplinary Treatment) that induction chemotherapy with TPExtreme protocol (cetuximab + albumin-paclitaxel + cisplatin) for patients with locally advanced oral cancer can significantly reduce the tumor with a good objective response, which can create good conditions for surgery. Therefore, for patients sensitive to induction chemotherapy, there are no authoritative guidelines and clinical studies to say what is the scope of surgery. One option is for the thoroughness of the tumor resection, which is still the same as the scope of the tumor before induction therapy, but the scope of the surgery is still large, and the damage to the patient's quality of life is also serious. The other option is to perform modified radical surgery according to the scope of residual tumor lesions after induction therapy, with less trauma and less damage to the quality of life. Postoperative radiotherapy (chemical) therapy is to reduce the risk of recurrence. Our preliminary clinical practice also shows that Patients sensitive to induction chemotherapy can obtain better survival rate and quality of life after comprehensive treatment including modified radical surgery. This treatment mode is feasible, but the overall efficacy evaluation needs further study. Therefore, in this real world prospective clinical study, patients with oral cancer sensitive to induction chemotherapy will be treated with modified radical surgery or traditional radical surgery in full compliance with the patient's wishes. Through clinical observation and follow-up statistics. To explore the effects of two treatment regimens on survival rate and quality of life in order to find the best treatment mode.

Cervical lymph node metastasis is the most important prognostic factor of oral squamous cell carcinoma (OSCC). Therapeutic neck dissection (I-V region) has always been regarded as the standard scheme of neck surgery for patients with cN+ OSCC and however, it has brought obvious side effects, which seriously affects the postoperative quality of life of patients. In addition, excessive neck lymph node dissection will also affect the local immune function of patients to some extent and reduce the body's response to immunotherapy. Lymph node metastasis of primary oral squamous cell carcinoma follows certain rules. Most of the metastatic areas are I-II, and low-level metastasis is very rare. Therefore, more than 90% of patients with cN+ oral squamous cell carcinoma who have undergone Therapeutic neck dissection may have suffered from "excessive dissection of area of IV and V". Both the long-term clinical experience of surgeons and a large number of recent retrospective studies show that elective neck dissection (I-III region) is safe enough for patients with oral squamous cell carcinoma of cN1 and part of cN2.There is clearly a need therefore for a large randomized trial that will resolve the issue either way once and for all.
