Adjunctive radiotherapy in the treatment of cutaneous squamous cell carcinoma with perineural invasion

Perineural invasion is a feature associated with significantly poorer outcomes when present in cutaneous squamous cell carcinoma (CSCC). The incidence of this subset of CSCC continues to rise in the US, as does the confusion surrounding exactly how it should be managed. While management typically involves excision, considerable debate exists as to the appropriate use of adjuvant radiotherapy (ART) in addition to excision. This article reviews the current relevant evidence for the use of ART. J. Surg. Oncol. 2011;104:104–105. © 2011 Wiley-Liss, Inc.
