Filter by:The overall aim of the project is to gain knowledge about the expected course of nevoid basal cell carcinomas and the usefulness of dermatoscopy in young individuals with Gorlin syndrome. Clinical experience and some case-reports suggest that nevoid basal cell carcinomas have an indolent course with slow growth and that they can sometimes regress. However, no systematic research has previously been performed. Increased knowledge about nevoid basal cell carcinomas and the use of dermatoscopy could be of great clinical value in the follow-up and treatment of individuals with nevoid basal cell carcinoma syndrome.
Rationale: Keratinocyte skin cancer is known to influence the HRQoL in a specific way. Derived utility values are required for cost-effectiveness analyses of new interventions. However there is no sensitive tool to capture HRQoL that translates into utilities available. Objective: To document the exact HRQoL in patients with in KC using the generic EQ-5D-5L questionnaire, as well as the TTO, 15D and the BaSQoL questionnaire, and to develop health utilities based on these tools. Study design: Longitudinal observational study (at time 0 and time 0 +12 months). Study population: Patients aged ≥18 years consulting a dermatologist or their GP for diagnosis, treatment or follow-up of a (pre)malignant skin lesion(s).
The purpose of the study is to evaluate the ability and efficacy of using a polarization-enhanced reflectance and fluorescence imaging device, PERFIS, (see the Device Brochure) for demarcation of nonmelanoma skin cancer margins prior to surgery. PERFIS is a harmless and non-invasive device that has been used to image biological tissue both in vitro and in vivo. In this study it will be used to image nonmelanoma skin cancer lesions prior to surgery. The use of PERFIS will not affect patient care or treatment decisions in any way. No extra tissue will be used for imaging.
Currently, we conduct a prospective, randomized trial comparing the outcome of surgical excision with the outcome of curettage in nodular and superficial BCCs. Larger BCCs and micronodular or sclerosing BCCs are not included in the randomized study. They are mainly operated using three-dimensional histology (3D-histology, micrographic surgery). In this observational study we measure the cosmetic result and the recurrence rate of all BCCs not included in the randomized trial.
