Filter by:A proactive speech-language pathologist program can be successfully established as part of the multidisciplinary care of patients with head and neck squamous cell carcinoma and improve patient quality of life.
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.
This phase I trial studies the side effects and best dose of cord blood-derived expanded allogeneic natural killer cells (donor natural killer [NK] cells) and how well they work when given together with cyclophosphamide and etoposide in treating children and young adults with solid tumors that have come back (relapsed) or that do not respond to treatment (refractory). NK cells, white blood cells important to the immune system, are donated/collected from cord blood collected at birth from healthy babies and grown in the lab. Drugs used in chemotherapy, such as cyclophosphamide and etoposide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving NK cells together with cyclophosphamide and etoposide may work better in treating children and young adults with solid tumors.
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).
Oral cancer is a major health problem worldwide, accounting for 274,000 new cases and 145,000 deaths annually. On average, half of the patients die within 5 years of an oral cancer diagnosis. Most troubling, however, is the lack of significant change in prognosis for this disease over the last 4 decades, even in developed nations. Even when successful, treatment of oral cancer can be devastating due to diminished quality of life and disfigurement. The key to controlling this disease is early identification of lesions that are at high risk of progression and provide effective treatment. The overall objective of the team is to integrate clinical, pathological, molecular, and imaging data to create a robust oral cancer risk model to predict the risk of progression of OPLs and to develop population-wide cost-effective prevention strategies for high-risk oral premalignancies. The project will involve 4 specific aims as described in detail below. Aim 1. To use molecular data to stratify low-grade OPLs into high- and low-risk groups. Aim 2. To evaluate the cost-effectiveness of various follow-up frequency that use LOH at chromosome 9p21 as a risk marker. Aim 3: To evaluate the specificity and sensitivity of using imaging technologies as a tool for the decision of the high-grade or high-risk biopsy site. Aim 4. To assess the clinical utility of a miRNA expression signature derived from serum collected from patients with oral cancer and OPLs.
Primary Objective: To determine the 2-year distant failure rate of maintenance tegafur-uracil in patients with squamous cell carcinoma of oral cavity with extracapsular spreading of lymph nodes. Secondary Objectives: - To determine the 2-year locoregional failure rate. - To evaluate the 2-year overall survival (OS) rate. - To evaluate the 2-year progression-free survival (PFS) rate. - To assess the safety profiles.
Cervical nodal metastasis is the most certain prognostic factor in oral cancer. Appropriate management of the neck is therefore of paramount importance in the treatment of oral cancer. However, there is still some controversy on the treatment of early maxillofacial malignancies. Currently, investigators have no accurate uniform treatment standards, including the National Comprehensive Cancer Network (NCCN) recommended between surgery and radiotherapy options. Clinical evaluation indicated that lymph node-negative patients eventually 25%-35% had cervical node metastasis. Therefore, for the majority of patients with true node-negative, preventive cervical lymph node dissection is obviously over-treatment, and lower quality of life. Radiotherapy can avoid such surgery.
