Objective:
To examine factors that affect the positive surgical margins of facial basal cell carcinoma (BCC) and investigate whether the surgical margin value can be narrowed in early-stage facial BCCs.
Methods:
Ninety-five patients were divided into the three groups based on prognosis: good (n = 48), mixed (n = 32), and poor (n = 15). The good prognosis group (group 1) included nodular and superficial subtypes; the mixed prognosis group (group 2) included nodular-infiltrative, nodular-micronodular, and nodular-sclerosing subtypes; and the poor prognosis group (group 3) included infiltrative and micronodular subtypes.
Results:
Groups 1 and 2 differed from each other significantly in terms of positive surgical margin (P = .002) and tumor thickness (P = .008), but group 3 did not (P = .851 and P = .804, respectively). With regard to surgical method (primary vs local flap repair), only tumor localization varied significantly (P < .001).
Conclusions:
Groups differed significantly in terms of surgical margin positivity, the distance of the tumor to the surgical margin, and the tumor thickness. The intact surgical margin was 2 mm on average in this study, and the authors suggest that it may be possible to revise the surgical margin values recommended in the literature.
