Study information
Scientific title
A randomised controlled trial of the effectiveness of excisional surgery versus imiquimod 5% cream for long-term clinical success rate in patients with nodular and superficial basal cell carcinoma
Acronym
SINS
Study hypothesis
1. Can imiquimod 5% cream applied topically give an acceptable and clinically useful success rate (3 year clinical clearance) and acceptable side effect profile when compared with excision surgery for superficial and nodular basal cell carcinoma (BCC) at low risk sites?
2. Is imiquimod more cost effective than surgery for low-risk BCC?
3. Does imiquimod result in a more aesthetically acceptable result than conventional excision?
4. Do certain phenotypic features and gene polymorphisms predict tumour responsiveness to treatment?
