Dermoscopy vs Standard Marking for the Completeness of Excision of Keratinocyte Skin Cancers: The ClearMark Trial

What is the study about? This study aims to improve the success rate of removal surgery for a common type of skin cancer. We will compare two different methods of marking (drawing where to remove) the skin before removing the lump: the normal method using magnifying glasses and theatre lights, and our proposed method using a handheld magnifying device called a dermatoscope. Why is this study important? Skin cancer is the most common cancer in the UK. Currently, up to 10-11% of surgeries do not remove all of the cancer, which means patients may need more treatment. We do not know whether using a dermatoscope can help surgeons remove all of the cancer more often or not. If it does, it could prevent patients needing more surgery or time in hospital. What will happen during the study? A computer will randomly allocate each participant to marking using the normal method, or using a dermatoscope. The surgery will then proceed as usual. After the surgery, patients will be asked to fill in a simple questionnaire about their thoughts. We will collect data from patients' notes to monitor the success of the surgery and any more treatments needed. What will we measure? We will check participants records to see if the cancer was entirely removed. This is reported by a pathologist whenever a skin lump or bump is removed. In time, we will also look at 5-year recurrence of cancer, the need for additional treatments, any problems from the marking process, how happy patients are with the pr…
