Filter by:Cancer of the oral mucosa, also known as oral squamous cell carcinoma (OSCC), occurs as an ulceroproliferative lesion that can develop at any site in the mouth, from the lips to oropharynx. OSCC (Oral squamous cell carcinoma) is a biologically aggressive tumor and this has piqued interest in research into several prognostic histopathological indicators during the past few decades. The AJCC 8th edition TNM staging system incorporates histopathological factors including depth of invasion (DOI) that affect patient outcomes. Numerous studies have linked a poor prognosis and increased locoregional failure with certain "patterns of invasion" (POI) in OSCC. However, this factor is not utilized for treatment decision making and for outcome assessment. The management and prognosis of oral squamous cell carcinoma (OSCC) depends on tumor stage, differentiation, perineural and lymphovascular invasion, depth of invasion, margin status, lymph node (LN) metastasis and extranodal extension. We will evaluate the relationship of these histopathological parameters with cohesive and non cohesive worst patterns of invasion (WPOI) in OSCC. The purpose of this cross-sectional study is to determine that presence of non-cohesive WPOI is associated with advanced T stage, poor differentiation, PNI, greater depth of invasion, and higher chances of nodal metastasis. WPOI is associated with poor DFS (disease free survival), treatment intensification in early stage disease with non-cohesive WPOI may improve survival. Therefore, it should also be included in routine reporting protocol for OSCC to aid in describing the aggressive behaviour of disease.
The 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.
PRV211 is a sterilized nano engineered delivery system intended for intraoperative chemotherapy treatment for all solid tumor surgeries immediately following surgical excision. The goal is to treat the tumor bed locally, eliminating any remaining micro metastases or close margins that are unable to be fully resected while avoiding system circulation. This study will enroll up to 40 subjects. In this study both safety and efficacy will be evaluated. All subjects will be monitored for possible DLTs.
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.
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.
This study was designed to verify the role of salivary LINC00657 as a diagnostic marker in oral squamous cell carcinoma (OSCC) patients as compared to oral lichen planus (OLP) (as an example of oral potentially malignant lesions) and normal individuals, and to show its relation to miR-106a. A total of 36 participants were included.
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.
This study aims to investigate the efficacy and safety of neoadjuvant Toripalimab combined with Nimotuzumab in primary limited stage oral squamous cell carcinoma prior to radical therapy.
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.
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.
