Treatment results with 5-mm surgical excision in nonmelanoma skin cancers: Analysis of 234 cases

Background: Basal cell carcinoma and squamous cell carcinoma constitute the majority of nonmelanoma skin cancers. In our study, we analyzed our results of nonmelanoma skin cancer treatment with 5-mm surgical excision and compared them with the literature. Material and Methods: Patients treated at Ankara City Hospital Plastic, Reconstructive, and Aesthetic Surgery Clinic between February 2019 and March 2022 were included in this study. Demographic data, anatomical region, tumor subtype/differentiation, surgical margins, reconstruction method, and recurrence parameters were recorded. IBM SPSS Statistics (version 26.0) was used for the data analysis. Results: Of the 234 cases, 163 were reported as basal cell and 71 as squamous cell cancer. Margin positivity with 5-mm surgical excision was 14.1% and 16.9% in basal and squamous cell cancer, respectively. Nineth-month recurrence rates were 4.2% and 19.7% in basal and squamous cell cancer, respectively. Conclusions: All surgical margin positivity and recurrences were located in the head and neck regions, revealing the importance of developing treatment references according to the anatomical region.
