Clinical Trial Summary

Basal cell carcinoma (BCC) is the most prevalent form of cancer among the Caucasian population. There are several subtypes of BCC with different clinical characteristics and treatment strategies. Superficial and nodular BCCs are low-risk BCC subtypes. The diagnosis and subtype of BCC can be confirmed by means of punch biopsy, but non-invasive diagnosis by means of Optical Coherence Tomography (OCT) is proven to be a non-inferior alternative diagnostic instrument. Besides, non-invasive topical treatment is recommended as valuable treatment alternative to surgical excision for low-risk BCC.

Since non-invasive diagnosis and treatment for low-risk BCC is being implemented into daily practice, we want to evaluate the real-world effectiveness of different invasive and non-invasive diagnostic and treatment strategies in the management of low-risk BCC. This real-world evidence will enhance our understanding of these management strategies for low-risk BCC in daily practice.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Effectiveness of imiquimod versus surgical excision	Treatment success, expressed as the proportion of tumor free patients	1 year post-treatment
Secondary	Adverse effects	Incidence and severity of adverse effects	During imiquimod treatment, reported by the patient
Secondary	Mean treatment compliance for patients in the imiquimod group	In percentages	During treatment, reported by the patient in a treatment checklist
Secondary	Cosmetic outcome	Patient-reported satisfaction with cosmetic result of treatment area, expressed as mean score on the DASS questionnaire	1 year post-treatment
Secondary	Patient treatment satisfaction	Patient-reported satisfaction with treatment, expressed as the proportion of patients reporting to be satisfied with their treatment on a 4-point Likert-scale.	1 year post-treatment
Secondary	Cost-effectiveness analysis	Cost-effectiveness will be analysed from a health-care perspective: pre-, during and post-treatment costs will be recorded and analysed and compared in both treatment groups using a cost-effectiveness analysis (CEA)	1 year post-treatment
