Role of Intraoperative Clean Surgical Margin Determined With Lesion Size and Duration to Obtain Apropriate Histological Clean Surgical Margin in High-Risk Basal Cell Carcinoma Patients, According to National Comprehensive Cancer Network Criteria

We aimed to elucidate the role of intraoperative clean surgical margin (iCSM) determined according to lesion size and duration to obtain appropriate histological clean surgical margin (hCSM) in high-risk basal cell carcinoma (BCC) patients evaluated according to National Comprehensive Cancer Network (NCCN) criteria considering the tumor size and/or location. The contribution of lesion area to determine iCSM was also evaluated. Patients with high-risk BCC requiring surgical management were included. iCSM, hCSM, and clinical variables including sec, age, longest edge, location and area, and follow-up duration were recorded. In total, 96 lesions were evaluated. Lesions were mostly located in the mask area and other face region (93.8%). Lesions located on the nose comprised 50%, 34.1%, and 26.3% in the BCC-5, BCC-7, and BCC-10 lesions, respectively. The hCSMs were positive in 11.5%, 9.1%, and 3.8% of the BCC-5, BCC-7, and BCC-10 lesions, respectively. The deep surgical margin was positive in 15.4%, 4.5%, and 7.7% of the BCC-5, BCC-7, and BCC-10 lesions, respectively. The calculated risk for the positive surgical margin if the BCC-10 lesions were done like the BCC-7 was 15.4%. No recurrence was during follow-up duration. As supported by the findings of the present study, to obtain an adequate hCSM in the high-risk BCC lesions, the iCSM determined according to NCCN recommendations may not be optimal. Nevertheless, after their categorization according to lesion size and disease dura...
