Basal Cell Carcinoma
Conditions
Brief summary
The aim of this study is to show that the Nd:YAG laser could be a promising alternative treatment option in the management of low-risk basal cell carcinomas with similar high efficacy rates to surgery, and low recurrence rates evaluated over a time period of one year. Reflectance confocal microscopy, optical coherence tomography and clinical examination are used prior to confirm the clinical diagnosis of the basal cell carcinoma and for premargination of the tumor. The optical coherence tomography will also be used post treatment to confirm clearance of the basal cell carcinoma and to monitor treatment response.
Interventions
DEVICECynosure Cynergy Nd:YAG Laser 1064nm
The Nd:YAG Laser 1064nm is intended to be used as a treatment option in individuals suffering from low-risk basal cell carcinoma(s).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Treatment efficacy of Nd:YAG Laser 1064-nm for low risk basal cell carcinomas | 8 weeks after the treatment | Clearance rate of basal cell carcinomas after 1-3 Nd:YAG laser treatments evaluated by clinical inspectation, dermatosopy and optical coherence tomography. |
| Recurrence Rate after Nd:YAG Laser treatment | 12 months | To assess the recurrence rate after a long-term follow-up of 6 and 12 months |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of Treatment-Emergent Adverse Events (Safety and Tolerability) | 6 and 12 months after treatment | To assess treatment tolerability of the Nd:YAG Laser 1064-nm (e.g. pain according to a Numerical rating scale, scarring, wound healing, secondary infection rate) |
| Cosmetic outcome after laser treatment | 6 and 12 months after treatment | This will be assess according to an assessment scale including following parameters: * Pigmentation: hyperpigmentation, hypopigmentation, normal * Vascularity: pink, red, purple, normal * Pliability: firm, contracture, supple, yielding, ropes, normal * Scarring: yes, no * Overall opinion: Rating on a scale from 1-5 (school note system) Separate evaluation of observer and patient. |
