Evaluating the risk of cancer in patients with oral lichen planus

Observational Study of an OLP Patients Cohort: Characteristics, Comorbidities, Risk Factors for Malignant Transformation

Catholic University of the Sacred Heart · NCT06934863

This study is looking to see how often oral lichen planus turns into cancer in patients over time and what factors might increase that risk.

What this trial studies

This observational study aims to assess the rate of malignant transformation in patients diagnosed with oral lichen planus (OLP) over a long-term follow-up period. It will also explore the clinical characteristics of these patients to identify potential risk factors associated with malignant transformation. The study will analyze data from a cohort of patients to evaluate therapeutic effects and features related to OLP. By understanding these factors, the research seeks to provide insights into the management of OLP and its potential progression to oral carcinoma.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals with a clinical-histological diagnosis of oral lichen planus who have consented to personal data treatment and have a minimum follow-up of six months.

Not a fit: Patients with oral lichenoid lesions or those who have a history of hematopoietic stem cell transplant may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help identify patients at higher risk for malignant transformation, leading to improved monitoring and treatment strategies.

How similar studies have performed: While there have been studies on oral lichen planus, this specific focus on malignant transformation rates and risk factors is relatively novel.
