Cancer Chemoprevention by Metformin Hydrochloride in Oral Potentially Malignant Lesions
Oral CancerOral 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?
EHR-embedded OCDT in Breast or GI Cancer
Oral Cancer Directed TherapyBreast Cancer2 moreThis is research study is for participants with advanced breast or gastrointestinal cancer who have been taking oral chemotherapy medication (Oral Cancer Directed Therapy). This study is to help researchers better understand gaps in assessing oral chemotherapy patient toxicity at home, adherence to treatment and integrate toxicity/adherence reporting.
Low-Cost, Portable Flexible Nasopharyngoscope in Head & Neck Cancers in Low Resource Settings -...
Head and Neck CancerOral CancerThis study aims to develop and evaluate a low-cost, portable, flexible nasopharyngeal scope (FNS) used to assess head and neck cancers (HNC) in low resource settings. The FNS will be compared to an endoscope that is used as standard of care (SOC) in terms of ease of use, image quality, and perceived pain. The ultimate goal is to compare the ease of use between the FNS to what is used in SOC.

Salivary and Serum Levels of Chemerin and MMP-9 in Oral Premalignant and Malignant Lesions
Precancerous ConditionsOral Cancer45 individuals were subdivided into 3 groups, 15 patients with oral premalignant lesions, 15 patients with oral malignant lesions and 15 control individuals. Levels of chemerin and MMP-9 were evaluated in serum and saliva of these subjects utilizing the ELISA technique.
Assessment of Mandibular Bone Invasion With MRI Using SWIFT
Oral CancerThe primary objective of this study is to improve the diagnostic accuracy and specificity of MRI in detecting the degree of bone involvement and invasion in oral cancer. The presence and degree of bone invasion determines the extent of surgery and has great effect on the morbidity of patients with oral cancer and bone/soft tissue tumors. MRI scanning in 3 Tesla (3T) and 4Tesla (4T) MR magnet will be performed on up to 10 patients with possible maxillofacial and/or mandibular bone invasion. We will then compare the conventional imaging results of the patients with 3T and 4T MRI results and post operative pathology results.
Collaborative Seamless Care in Oncology : Measure and Reinforce Safety and Adherence to Oral Cancer...
CancerThe purpose of this study is to implement a support interdisciplinary program(oncologists, pharmacists, physicians, nurses, leagues against cancer) of medication adherence to oral oncology treatments. The aim is to ensure continuity of care between professionals,effectiveness of treatment and patient safety.
Oral Cancer Screening Among Nursing Home Dentists in Ohio
Head and Neck CancerRATIONALE: Learning about oral cancer screening practices, knowledge, and opinions of Ohio nursing home dentists may help the study of oral cancer in the future. PURPOSE: This clinical trial is studying oral cancer screening among nursing home dentists in Ohio.
Rehabilitation Outcomes in Head and Neck Survivors
Head and Neck CancerOral CancerHead and neck cancer is prevalent in Taiwan, and oral cancer is the most common location. Patients with advanced stage of the disease need extensive tumor excision with neck dissection. Secondary reconstructive surgeries using free flap could improve the postoperative function or appearance of cancer survivors. Advanced treatments make survival rates increased. Effects of treatment for oral cancer develop shoulder dysfunction, speech, mastication, donor site morbidity and psychological issues. Physical therapy may have benefits for temporomandibular joint function, shoulder pain relief, muscle performance, and oral structures coordination. Return to work in the number of cancer survivors is a realistic outcome. Rehabilitation effects on functional restorations and quality of life for head and neck survivors are needed for further studied. The purpose of this project is to explore the rehabilitation effects following head and neck reconstructive survivors. The investigators measure temporomandibular joint function, shoulder function, pain monthly. Physical functions, self-reported quality of life, and the status of return to work are measured 3 and 6 months after surgery. This prospective study could help to predict the rehabilitation outcomes and benefits.
Verification of Saliva MMP-1 as a Diagnostic Marker of Oral Cavity Cancer
Oral Squamous Cell CarcinomaThe study is designed to measure salivary matrix metalloproteinase-1 (MMP-1) using the enzyme-linked immunosorbent assay (ELISA) we developed previously in patients with oral potentially malignant disorders (OPMD), oral squamous cell carcinoma (OSCC), and healthy participants. The purpose of this study is to evaluate the potential of the newly developed salivary MMP-1 ELISA as an adjunctive tool to aid in diagnosis of OSCC.
