Study of Clinical and Molecular Features in Oral Premalignant and Malignant Tumors to Understand Tumor Behavior, Treatment Response, and Patient Outcomes

What this Trial Is About

Researchers are studying oral premalignant and malignant tumors to understand the clinical, environmental, and genetic factors that increase the risk of developing oral cancers and their aggressive behaviors. The study aims to identify molecular and clinical markers that predict diagnosis, treatment response, toxicity, and overall outcomes. This observational study also seeks to understand how treatment and clinical factors affect patients quality of life and functional outcomes over time. Participants will be observed without receiving experimental treatments standard care such as radiation may be involved as part of usual treatment. Biological samples including tissue biopsies and other biomarkers will be collected before, during, and after treatment. These samples will help researchers develop and validate biomarkers related to disease burden and treatment response. The study includes patients undergoing various treatments like targeted therapy, immunotherapy, surgery, chemotherapy, and radiotherapy. Participants will provide biological samples and complete assessments of functional outcomes and quality of life using validated questionnaires such as the MD Anderson Symptom Inventory for Head and Neck Cancer. Data will be collected over up to five years to monitor symptoms, swallowing difficulties, and other long-term effects. This information helps researchers understand prognosis and treatment impact. Participants clinical and molecular data will be linked with previously collected specimens where applicable.
