Filter by:This is a two-staged clinical trial to investigate the feasibility of intraoperative Fluorescence Imaging (FLI) to adequately assess tumor margins in patients with oral cancer using cRGD-ZW800-1.
This study investigates if head and neck squamous cell carcinoma can be tracked with cell-free tumor DNA, RNA or HPV-DNA, in blood samples from patients referred with suspicion of cancer, and if it can be used in detecting recurrence in patients already diagnosed and treated for head and neck squamous cell carcinoma.
The presence of lymph node metastasis is an important factor in determining the appropriate treatment plan in patients with OSCC. However, detection of lymph node metastases by means of current imaging modalities is limited. 20-30% of patients with a clinically negative neck (cN0) harbour lymph node metastasis that were not detected during clinical diagnostic workup, which are referred to as occult lymph node metastasis. Therefore, patients with a risk of lymph node metastasis higher than 20% undergo a sentinel node procedure (SNP) or elective neck dissection (END), which means that a substantial part of patients is overtreated. There is need for an additional non-invasive diagnostic tool that can identify lymph node metastasis and thereby support the decision making for treatment of the neck. The main objective of this study is to evaluate if EGFR-positive cervical lymph node metastasis can be detected non-invasively with multispectral optoacoustic imaging using cetuximab-800CW as contrast agent in patients with oral squamous cell carcinoma.
Control of cell death is frequently disrupted in cancer resulting in overgrowth of tumour cells. Caspase-8 is a key enzyme involved in controlling cell death. This study examines the importance of caspase-8 in oral cancer.
Background: Head and neck cancer is a group of cancers that start in the mouth, nose, throat, larynx and sinuses. The usual treatment is surgery, radiation, chemotherapy, or a combination of those. Approximately 50% of HPV-negative head and neck cancer patients that have been treated with any of these modalities will have a recurrence. For these patients, current treatment options include surgery and re-irradiation with chemotherapy, which can reduce symptoms and may stop the tumor from growing but in the majority of cases, only for a few months. In this trial, researchers want to see if they can cure or significantly lower the chance of head and neck cancer growing back or spreading by adding the new agent birinapant to re-irradiation. Objective: To test the safety of birinapant and re-irradiation at different doses in patients with head and neck cancer. Eligibility: Adults age 18 and older with head and neck cancer who are candidates for re-irradiation. Design: Participants will be screened with a review of their medical record. Participants will have exams and procedures that are part of their usual care. Participants will also have a test of heart activity before treatment. Participants will have urine pregnancy tests, if female. Participants will have blood and tumor samples taken 2 times and stored for research. The study lasts 6 weeks. Participants will get radiation for 5 days a week (Monday Friday) for all 6 weeks. Participant will get the study drug on 4 Tuesdays. They will get it in an arm vein over 30 minutes each time. About 4 weeks after the study ends, participants will have a follow-up visit. They will have a physical exam, health questions, and blood tests. Participants may have scans 4 times over the next 2 years. Participants will get an email or phone call every 6 months. Sponsoring Institute: National Cancer Institute
The study is designed to measure serum and salivary CYFRA21-1 levels using enzyme linked immunosorbent assay (ELISA) in patients with oral malignancy, oral potentially malignant lesions, and control subjects to evaluate the potential of CYFRA21-1 as a diagnostic marker for malignant transformation in potentially malignant oral mucosal lesions.
Oral squamous cell carcinomas (OSCCs) are among the most common types of head and neck cancers and are a major cause of significant morbidity. It was reported that 16- 62% of OSCCs develop from premalignant lesions, which often presents clinically as white or red mucosal patches known as leukoplakia and erythroplakia. The role of miRNA in cancer has been established by many studies that have shown that miRNA signatures (i.e., mRNA expression profiles) can be useful for classifying human cancers. These studies have identified "cancer related miRNAs through investigating expression profiles in matched normal and tumor tissues, as well as in body fluids. Metformin, one of most widely prescribed oral hypoglycemic agents, has recently received increased attention because of its potential anti-tumorigenic effects that are thought to be independent of its hypoglycemic effects. Evans et al. first found an association between metformin use and decreased cancer incidence. The study will reveal whether Systemic Metformin hydrochloride treatment given to patients with oral potentially malignant lesions improve the prognosis and prevent or at least reduce the incidence of malignant transformation?
Evaluation of the metformin drug effect as a drug that found to improve the quality of tissues, decrease signs & symptoms of cancer, and decrease histo-pathological criteria of dysplasia. This will be done by the aid of measuring salivary Micro RNA 31 & 210 in saliva in addition to measure cyclin A2 as an immuno-histochemical analysis.
Trial design: a randomized controlled trial. Eligibility criteria for participants: patients with primary early stage oral squamous cell carcinoma. Exclusion criteria: cancer of the floor of the mouth. Interventions: submandibular gland is preserved during neck dissection for patients of the experimental group; submandibular gland is removed during neck dissection for patients of the control group. Primary Parameters: survival rate, mortality rate
The purpose of this study is to compare any good or bad effects of using pembrolizumab (an experimental drug) and radiation therapy (RT), compared to using cisplatin chemotherapy and radiation therapy (RT) in the treatment of patients with head and neck squamous cell carcinoma (HNSCC).
