Overview
This research protocol is comparing the effectiveness of surgical excision to the "wait and see" approach for the management of oral leukoplakia and erythroleukoplakia in prevention of oral squamous cell carcinoma onset.
Description
Different treatments have been proposed for the management of oral leukoplakia (OL) in order to prevent oral squamous cell carcinoma onset. However, there is still no consensus on the most effective approach for the patients affected by such oral potentially malignant disorders. Surgery is often performed, but there is no randomized clinical trial which demonstrates its real effectiveness in preventing oral cancer onset.
A recent RCT compared surgical treatment with "wait and see approach" care in patients with nondysplastic OL, assuming that regular clinical follow-up could be considered a reliable standard of care among patients with nondysplastic oral leukoplakias.
The purpose of this study is to evaluate effectiveness of surgical excision in treating OL and or reducing the onset of potential oral squamous cell carcinoma, with a follow-up of 5 years. This study will be the first RCT comparing the effectiveness of surgery to "wait and see approach" in the management of both dysplastic and nondysplastic oral leukoplakias.
