Study information
Scientific title
A multi-centre, randomised controlled trial assessing the effectiveness of Lugol's Iodine to assist excision of moderate dysplasia, severe dysplasia and carcinoma in situ at mucosal resection margin of oral and oropharyngeal squamous cell carcinoma.
Acronym
LIHNCS
Study hypothesis
Lugol's iodine demonstrates dysplastic cells at the margins of oral cavity and oropharynx Squamous Cell Carcinoma (SCCa). Data from our pilot study have suggested that using this technique allows surgeons resecting these tumours to identify and remove dysplastic tissue at the time of cancer resection. Using Lugol's stain reduced dysplasia at tumour margins from 32% to 2.7%; p=0.001 (95% CI 15.35 - 43.24). This should reduce local recurrence rates for this cancer type and site.
As of 10/12/2010, this record has been updated as funding has been secured to now roll this out as a larger multicentre trial. All updates to this record can be found in the relevant sections under the above update date. At this time, the anticipated start and end dates of the pilot study were extended to incorporate the main study; the initial details of the pilot study are as follows:
Initial anticipated start date: 01/03/2007
Initial anticipated end date: 01/06/2008
Please also note that the previous target number of participants for the pilot study was 164 participants, a further 300 will then be recruited for the main study.
As of 20/01/2011, the scientific title for this trial has been updated. The previous title was: "A prospective, multi-centre, randomised controlled trial looking at the effectiveness of Lugols Iodine to assist excision of marginal dysplasia at resection of oral and oropharyngeal squamous cell carcinoma".

Primary outcome measures
Current information as of 10/12/2010:
Rates of surface dysplasia, carcinoma-in-situ or carcinoma at surface mucosal margins in the Lugols treated group versus gold standard management. Subgroup analysis of T1 and T2 versus T3 and T4 primary tumours.
Initial information at time of registration:
Incidence of moderate to severe dysplasia or carcinoma in situ at resection margins, assessed immediately after resection.
Secondary outcome measures
Current information as of 10/12/2010:
1. Acceptability of the technique to surgeons carrying our surgery for oral cavity and oropharynx cancer
2. Effect of Lugols technique on any further treatment carried out (radiotherapy or further surgery)
3. Estimate of the two year locoregional recurrence rates in each group
4. Mean and range of volume of tissue removed by each method
Initial information at time of registration:
Five year local recurrence rates.
