Objective: Identification of factors that provoke the recurrence of basal cell carcinoma of the scalp after previous treatment and development of the method for predicting local recurrence of basal cell carcinoma of the scalp.
Materials and methods: 100 patients were studied, including 50 patients with newly diagnosed basal cell carcinoma of the scalp and 50 patients with recurrent basal cell carcinoma of the scalp. To predict recurrence, binary logistic regression models with risk factors for basal cell carcinoma of the scalp were evaluated.
Results: Diagnostically significant criteria for basal cell carcinoma of the scalp recurrence were identified for tumor localization in the nasal skin area (p=0.01), with a deep resection margin of less than 1 mm (p=0.03), and patient age.
Conclusion: A formula for predicting basal cell carcinoma (BCC) recurrence has been developed.
