Abstract

Basal cell carcinoma (BCC) is the most frequent form of skin cancer and is not a tumor with a lethal outcome if diagnosed and treated adequately. The gold standard for treatment is surgical excision with histologically safe margins. Even so, tumors excised with free margins may recur after a period of time. The identification of predictive factors for the recurrence of BCCs besides the localization, size and aggressive histology may be useful for the clinician. The aim of the present study was to identify clinical and pathological factors associated with recurrence in tumors with histologically free margins and assess via immunohistochemical staining, the expression of glioma‑associated oncogene homolog 1 (GLI1), yes‑associated protein (YAP), connective tissue growth factor (CTGF) and E‑cadherin as they are involved in the development of BCCs, in the hope of identifying markers that are predictive for recurrence. In total, 8 recurrent BCCs and 38 non‑recurrent tumors were analyzed. A Breslow index >2 (Se 100.0%, Sp 67.5%, P=0.008), Clark level >3 (Se 100.0%, Sp 47.5%, P<0.001), and excision margins both lateral (Se 87.5%, Sp 60.0%, P=0.04) and deep (Se 75.0%, Sp 82.5%, P<0.001) free from tumoral cells ≤1 mm proved to be predictive for recurrence in the present study. Recurrence may appear even after more than 3 years since the initial excision (Se 87.50%, Sp 70.0%, P<0.001). The expression levels of GLI1, YAP and E‑cadherin were not different in the recurrent vs. non‑recurrent BCCs. However, the low expression of CTGF may indicate a tumor with a higher aggressiveness. In conclusion, close follow‑up of patients with excised BCCs at least annually is recommended and re‑excision should be taken into consideration for locally advanced tumors especially if they are located in high‑risk areas or those with histologically free margins <1 mm.
