Real-world Evaluation of Diagnostic and Treatment Strategies in Low-Risk Basal Cell Carcinoma

Maastricht University Medical Center142 enrolled

Overview

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.

Outcomes

Primary Outcomes

Effectiveness of imiquimod versus surgical excision

Treatment success, expressed as the proportion of tumor free patients

Time frame: 1 year post-treatment

Secondary Outcomes

Adverse effects

Incidence and severity of adverse effects

Time frame: During imiquimod treatment, reported by the patient

Mean treatment compliance for patients in the imiquimod group

In percentages

Time frame: During treatment, reported by the patient in a treatment checklist

Cosmetic outcome

Patient-reported satisfaction with cosmetic result of treatment area, expressed as mean score on the DASS questionnaire

Time frame: 1 year post-treatment

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.

Time frame: 1 year post-treatment

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)

Time frame: 1 year post-treatment
