Node-positive cutaneous squamous cell carcinoma of the head and neck: Survival, high-risk features, and adjuvant chemoradiotherapy outcomes.

Abstract

Data lacks to guide treatment of regionally metastatic cutaneous head and neck squamous cell carcinoma (HNSCC). We conducted a retrospective review of 80 patients treated for regionally metastatic cutaneous HNSCC. The effect of various clinicopathologic variables on overall survival (OS) was investigated, in addition to outcomes by treatment modality. On multivariate regression, cutaneous primary >2 cm (p = .03) and extracapsular spread (ECS; p = .01) were significantly associated with decreased OS. Location of regional metastasis (neck vs parotid vs both) had no effect on OS (p = .2), nor did the presence of a cutaneous primary at the time of presentation (p = .9). The 3-year survival was 43%, 52%, and 49% for surgery alone, adjuvant radiation, and adjuvant chemoradiation, respectively. Fifty-one percent of patients had a recurrence of their disease. Regionally metastatic cutaneous HNSCC is an aggressive disease associated with high recurrence rates. Patients with tumors >2 cm and ECS have poorer OS despite adjuvant therapy. © 2017 Wiley Periodicals, Inc. Head Neck 39: 881-885, 2017.
