Abstract
This review is part three of a series assessing the evidence for Mohs micrographic surgery (MMS) for treatment of cutaneous malignancies. The evidence for using MMS to treat cutaneous squamous cell carcinoma (cSCC) is presented and discussed. Medline, Embase and Cochrane databases were searched and 39 papers were identified. We included all clinical trials and observational studies including retrospective reports. We excluded editorials and systematic reviews or meta-analyses. We categorised the evidence under the following headings: tumour recurrence, specific site outcomes (ear, lip, scalp and periocular), cSCC with PNI, and cost effectiveness. Whilst there are many observational studies indicating the potential benefits of MMS in the management of certain cSCCs, no randomised controlled trials (RCT) were identified. This evidence suggests that MMS has a lower recurrence rate than other treatments for cSCC, including standard excision. Many studies were single-armed, having no comparator but do demonstrate a low to very low recurrence rate of cSCC following MMS. Further methodologically robust studies with comparator arms are needed, including RCT evidence, given the overall quality of included studies was low and highly heterogeneous.
