Risk factors associated with relapse of eyelid basal cell carcinoma: results from a retrospective study of 142 patients
- 20 Downloads
Of skin cancers, 9% arise at the periocular level, constituting a significant threat due to the proximity to intracranial structures, such as the eyes, nerve endings and proximal tissues. Tumour recurrence can be frequent and represents a primary clinical challenge for the surgeon.
To present a retrospective study on the treatment of eyelid tumours at a tertiary care centre in Italy over an eight-year period and, in particular, to underline the risk factors associated with tumour relapse.
Materials & methods
Among a cohort of 205 patients, a retrospective study was conducted on 142 basal cell carcinoma (BCC) patients with eyelid tumours treated with surgical excision. Relapse-free survival was assessed using univariate Kaplan-Meier and multivariate Cox regression analysis.
Over an eight-year study period, we detected 23 cases of BCC recurrence, with tumour localization associating with tumour relapse, representing an independent risk factor. The extent of the area of excision was significantly associated with relapse, but not margin positivity whichwas associated with reduced relapse-free survival.
To minimize relapse of basal cell carcinoma during patient management, relevant factors to consider before and after tumour excision include tumour localization, margin invasion, and extension of the excision, but not the surgical technique used.
