Condition
Primary or first or second recurrent basal cell carcinoma
Intervention
Arm 1: Mohs micrographic surgery -
Tumours were excised with a margin of 3 mm under an angle of 45 degrees. The complete resection margins of the excised material were investigated histopathologically on horizontal frozen section slides. In case of positive resection margins, the procedure was repeated, until total clearance was obtained. The duration of the procedure was dependent of the number of mohs stages. Primary and secondary outcome measures were measured after 5 years follow-up.
Arm 2: surgical excision -
Tumours were excised with a margin of 3 mm under an angle of 90 degrees. The histolopathological examination was performed on vertical slides. The duration of the procedure was approximately 45 minutes per treatment. Primary and secondary outcome measures were measured after 5 years follow-up.

Drug names
Primary outcome measure
Recurrence of carcinoma after 5 years follow-up
Secondary outcome measures
1. Determinants of failure after 5 years of follow-up, tested with Cox regression analysis
2. Cost-effectiveness after 5 years of follow-up an incremental cost-effectiveness ratio was calculated, all personal and material costs of both treatments that have been made during procedures and follow-up were calculated by multiplying volumes of use with the cost per unit
