Objectives: Survival outcomes for advanced non-melanoma skin cancers of the head and neck treated with surgical resection are not well described in the literature. We aimed to describe outcomes for T3 and T4 cutaneoous squamous cell carcinoma of the head or neck treated with surgical resection at 1 tertiary academic medical center. Methods: We analyzed a retrospective cohort of patients diagnosed with T3 or T4 cutaneous squamous cell carcinoma (SCC) of the head or neck from 2005 to 2016 treated with definitive surgical resection. Survival outcomes were examined using Kaplan-Meier analysis, and multivariate analysis was completed with Cox proportional hazard model. Results: Forty-three patients met inclusion criteria. The mean age at diagnosis was 74.7 years (SD = 10.2), and 34 (79.1%) patients were male. Twelve (27.9%) patients were immunosuppressed. Radical resection, defined as temporal bone resection, orbital exenteration, calvarial resection, mandibulectomy, or maxillectomy, was performed in 25 (58.1%) cases. Final surgical margins were positive in 19 (44.2%) cases. Patients with tumors of the scalp/neck had a 1-year survival probability of 85.7%, and the probability of survival 1 year after a neck dissection was greater than 93%. Conclusion: Anatomical subsites, specifically scalp/neck tumors, tended to have worse overall survival. Positive final margins tended to indicate a worse prognosis, and overall survival and recurrence were not significantly different among patients who underwent radical surgical resection compared to soft tissue resection.

Abstract Perineural invasion (PNI) is frequently associated with aggressive clinical behaviour in head and neck cutaneous squamous cell carcinoma (HNcSCC) leading to local recurrence and treatment failure. This study evaluates the gene expression profiles of HNcSCC with PNI using a differential expression analysis approach and constructs a tailored gene panel for sensitivity and specificity analysis. 45 cases of HNcSCC were stratified into three groups (Extensive, Focal and Non PNI) based on predefined clinicopathological criteria. Here we show HNcSCC with extensive PNI demonstrates significant up- and down-regulation of 144 genes associated with extracellular matrix interactions, epithelial to mesenchymal transition, cell adhesion, cellular motility, angiogenesis, and cellular differentiation. Gene expression of focal and non PNI cohorts were indistinguishable and were combined for further analyses. There is clinicopathological correlation between gene expression analysis findings and disease behaviour and a tailored panel of 10 genes was able to identify extensive PNI with 96% sensitivity and 95% specificity.

Nonmelanoma skin cancers (squamous cell and basal cell carcinomas) occur at an epidemic rate in many countries with the worldwide incidence increasing. The sun-exposed head and neck are the most frequent sites for these cancers to arise and in most patients diagnosed with a cutaneous squamous cell carcinoma, local treatment is usually curative. However, a subset is diagnosed with a high-risk cutaneous squamous cell carcinoma. High-risk factors include size (> 2 cm), thickness/depth of invasion (> 4 mm), recurrent lesions, the presence of perineural invasion, location near the parotid gland, and immunosuppression. These patients have a higher risk (> 10–20%) of developing metastases to regional lymph nodes (often parotid nodes), and in some cases also of experiencing local morbidity (perineural invasion), based on unfavourable primary lesion and patient factors. Despite treatment, many patients developing metastatic cutaneous squamous cell carcinoma experience mortality and morbidity usually as a consequence of uncontrolled metastatic nodal disease. It is therefore important that clinicians treating nonmelanoma skin cancers have an understanding and awareness of these high-risk patients. The aim of this article is to discuss the factors that define a high-risk patient and to present some of the issues pertinent to their management.
