Condition
Topic: National Cancer Research Network, Ear; Subtopic: Head and Neck Cancer, Ear (all Subtopics); Disease: Head and Neck, Ear, nose & throat
Intervention
Group 1: Standard dispersible tablets of aspirin 75 mg (BNF) and be instructed to disperse one tablet thoroughly in one glass of 250 ml of water and use as mouthwash for 60 seconds twice a day.
Group 2: Two standard dispersible tablets of aspirin 75 mg (BNF) and will be instructed to dissolve the two tablets thoroughly in one glass of 250 ml of water and use as mouthwash for 60 seconds twice a day.
Group 3: Standard dispersible tablets of aspirin 300 mg (BNF) and be instructed to disperse one tablet thoroughly in one glass of 250 ml of water and use as mouthwash for 60 seconds twice a day.
Group 4: Standard dispersible tablets of aspirin 300 mg (BNF) and be instructed to dissolve the one tablet thoroughly in one glass of 250 ml of water and use as mouthwash for 60 seconds three times a day.
Patients will use the mouthwash for 6 weeks until they return for their second biopsy. Follow up is then whatever is required by the clinical team.

Drug names
Aspirin
Primary outcome measure
Level of COX expression, prostaglandin level and change in histological grade measured pre- and post-treatment. Measurement of the primary outcome measures will only occur once all patients have been recruited to the study. Pre and post treatment biopsy samples (6 weeks apart) are snap frozen and stored at -80°C.
Secondary outcome measures
All biochemical measures for the secondary outcomes will be measured at the same time. The histological grade of the tissue will be made within 7 - 10 days of each biopsy being taken as is normal clinical practive for these lesions. The tolerability and side effects will be ascertained on the patients return for their second biopsy (6 weeks after commencing the Aspirin).
