Feasibility Study to Estimate Number of Patients With Precancerous Areas in Their Airways and the Response to Gefitinib

Study Overview
=================
Brief Summary
-----------------
We are going to use a special type of bronchoscopy test to examine patients who have had previous surgical treatment for lung cancer or head and neck cancer. The aim is to determine a) whether we can identify precancerous changes in their airways b) whether this type of testing is acceptable and c) get an initial idea of whether a new drug called gefitinib has any effect on precancerous areas in the airway.

Official Title

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Incidence of high grade dysplasia of the bronchial epithelium in patients at high risk of lung dysplasia | Patients will have white/blue light bronchoscopy with biopsy of identified lesions. The incidence of high grade lung epithelial dysplasia will be recorded. | during the screening broncoscopy - carried out within the first month post consent | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Acceptability of screening patients as measured by success of trial recruitment |  | 12 months | 
| Response of high grade dysplasia to treatment (complete / partial / stable / progression) | To be estimated by photography & biopsy of the lesions & comparison with previous findings: Complete response: Complete resolution of a dysplastic lesion Partial response: Reduction of a dysplastic lesion by >=50% OR Reduction in grade of a high grade dysplastic lesion Progressive disease: Development of a new area of high grade dysplasia or invasive malignancy in an area of previous low grade dysplasia or normal epithelium OR Development of a higher grade lesion in an area of previous high grade dysplasia OR Increase in surface area of >=50%. Stable disease: None of the above. | 6 & 12 months | 
| Toxicity and acceptability of treatment (proportion of patients refusing study entry). |  | 2 weeks, 4 weeks, 3 & 6 months | 
| Successful biobanking of samples |  | 12 months |
