Study type Participant information sheet
Scientific titleA multi-centre, randomised controlled trial assessing the effectiveness of Lugol's Iodine in Surgical managemenT of Epithelial dysplasia in the oRal cavity and oropharynx
Study acronymLISTER
Study objectivesDoes intraoperative visualisation of dysplastic mucosa with Lugol’s Iodine assist in improving accuracy of excision of epithelial dysplasia of oral cavity and oropharynx?
Ethics approval(s)London-Harrow Research Ethics Committee, 13/10/2016, ref: 16/LO/0857
Health condition(s) or problem(s) studiedEpithelial dysplasia in the oral cavity and oropharynx
Intervention1. Standard Treatment Group: Surgical excision of epithelial dysplasia as per usual practice
2. Intervention Treatment Group: Surgical excision of epithelial dysplasia assisted by visualisation with Lugol’s iodine
Intervention typeProcedure/Surgery
Primary outcome measure(s)

Rates of surface dysplasia or carcinoma-in-situ at surface mucosal margins

Key secondary outcome measure(s)

1. Two-year incidence of histologically confirmed transformation to SCC in the oral/cavity/oropharynx
2. Occult SCC diagnosed histopathologically in excised mucosa
3. Surface area of mucosa excised
4. Extent of margin clearance in mm
5. Surgeon decision to re-excise at the same site following positive margins
6. Estimate of the two year recurrence rates of oral dysplasia
7. Acceptability of the technique to surgeons (intervention treatment group)
8. Safety of the technique (intervention treatment group)
9. Assessment of Quality of Life changes
